Abstract: BACKGROUND: Evidence suggests that truth telling and honest disclosure of cancer diagnosis could lead to improved outcomes in cancer patients. To examine such findings in Iran, this trial aimed to study the various dimensions of quality of life in patients with gastrointestinal cancer and to compare these variables among those who knew their diagnosis and those who did not. METHODS: A consecutive sample of patients with gastrointestinal cancer being treated in Cancer Institute in Tehran, Iran was prospectively evaluated. A psychologist interviewed patients using the Iranian version of the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire (EORTC QLQ-C30). Patients were categorized into two groups: those who knew their diagnosis and those who did not. Independent sample t-test was used for group comparisons. RESULTS: In all 142 patients were interviewed. A significant proportion (52%) of patients did not know their cancer diagnosis and 48% of patients were aware that they had cancer. They were quite similar in most characteristics. The comparison of quality of life between two groups indicated that those knew their diagnosis showed a significant lower degree of physical (P = 0.001), emotional (P = 0.01) and social functioning (P < 0.001), whereas the global quality of life and other functional scales including role functioning and cognitive functioning did not show significant result. There were no statistically significant differences between symptoms scores between two groups, except for fatigue suggesting a higher score in patients who knew their diagnosis (P = 0.01). The financial difficulties were also significantly higher in patients who knew their cancer diagnosis (P = 0.005). Performing analysis of variance while controlling for age, educational status, cancer site, and knowledge of cancer diagnosis, the results showed that the knowledge of cancer diagnosis independently still contributed to the significant differences observed between two groups. CONCLUSION: Contrary to expectation the findings indicated that patients who did not know their cancer diagnosis had a better physical, social and emotional quality of life. It seems that due to cultural differences between countries cancer disclosure guidelines perhaps should be differing.

Abstract: BACKGROUND: Female sexual dysfunctions (FSD) are prevalent multifactor problems that in general remain misdiagnosed in primary health care. This population-based study investigated help-seeking behaviors among women with FSD in Iran. METHODS: This was a cross sectional study carried out in Kohgilouyeh-Boyer-Ahmad province in Iran. Using quota sampling all sexually active women aged 15 and over registered in primary health care delivery centers were studied. Experience of sexual problems was assessed using an ad-hoc questionnaire (Female sexual dysfunction: help-seeking behaviors survey) containing 14 items. Trained female nurses interviewed all participants after a verbal informed consent. Data were analyzed in a descriptive manner. RESULTS: In all 1540 women were studied. Of these, 786 (51%) cases had experienced at least one of the FSD problems. Results showed that 35.8% of women with FSD had sought no professional help and the most reasons for not seeking help were identified as: 'time constraints' and believing that it 'did not occur to me' (39.1 and 28.5% respectively). Sixty one percent of women who sought help for FSD reported that 'doctor gave me a definite diagnosis' and 'a definite treatment plan was given' in 57% of cases. CONCLUSION: The study findings indicated that FSD problems were prevalent and many women did not seek help for their problem. Finding 'time constraints' and believing that the problem 'did not occur to me' as the most cited reasons for not seeking help might facilitate to understand potential barriers that exist in recognition and treatment of the female sexual dysfunctions. Since FSD might have a negative impact on interpersonal relationships and women's quality of life, it seems that there is need to address the problem both at local and national primary health care services.

Abstract: BACKGROUND: The objectives of this study were to test the factor structure and internal consistency of the 12-item General Health Questionnaire (GHQ-12) and the Subjective Vitality Scale (VS) in elderly French people, and to test the relationship between these two questionnaires. METHODS: Using a standard 'forward-backward' translation procedure, the English language versions of the two instruments (i.e. the 12-item General Health Questionnaire and the Subjective Vitality Scale) were translated into French. A sample of adults aged 58-72 years then completed both questionnaires. Internal consistency was assessed by Cronbach's alpha coefficient. The factor structures of the two instruments were extracted by confirmatory factor analysis (CFA). Finally, the relationship between the two instruments was assessed by correlation analysis. RESULTS: In all, 217 elderly adults participated in the study. The mean age of the respondents was 61.7 (SD = 6.2) years. The mean GHQ-12 score was 17.4 (SD = 8.0), and analysis showed satisfactory internal consistency (Cronbach's alpha coefficient = 0.78). The mean VS score was 22.4 (SD = 7.4) and its internal consistency was found to be good (Cronbach's alpha coefficient = 0.83). While CFA showed that the VS was uni-dimensional, analysis for the GHQ-12 demonstrated a good fit not only to the two-factor model (positive vs. negative items) but also to a three-factor model. As expected, there was a strong and significant negative correlation between the GHQ-12 and the VS (r = -0.71, P < 0.001). CONCLUSION: The results showed that the French versions of the 12-item General Health Questionnaire (GHQ-12) and the Subjective Vitality Scale (VS) are reliable measures of psychological distress and vitality. They also confirm a significant negative correlation between these two instruments, lending support to their convergent validity in an elderly French population. The findings indicate that both measures have good structural characteristics.

Abstract: BACKGROUND: Iraq used chemical weapons extensively against the Iranians during the Iran-Iraq war (1980-1988). The aim of this study was to assess the health related quality of life (HRQOL) in people who had ophthalmologic complications due to the sulfur mustard gas exposure during the war. METHODS: The Veterans and Martyrs Affair Foundation (VMAF) database indicated that there were 196 patients with severe ophthalmologic complications due to chemical weapons exposure. Of these, those who gave consent (n = 147) entered into the study. Quality of life was measured using the 36-item Short Form Health Survey (SF-36) and scores were compared to those of the general public. In addition logistic regression analysis was performed to indicate variables that contribute to physical and mental health related quality of life. RESULTS: The mean age of the patients was 44.8 (SD = 8.7) ranging from 21 to 75 years. About one-third of the cases (n= 50) reported exposure to chemical weapons more than once. The mean exposure duration to sulfur mustard gas was 21.6 years (SD = 1.2). The lowest scores on the SF-36 subscales were found to be: the role physical and the general health. Quality of life in chemical warfare victims who had ophthalmologic problems was significantly lower than the general public (P < 0.001). The results obtained from logistic regression analysis indicated that those who did not participate in sport activities suffer from a poorer physical health (OR = 2.93, 95% CI = 1.36 to 6.30, P = 0.006). The analysis also showed that poor mental health was associated with longer time since exposure (OR = 1.58, 95% CI = 1.04 to 2.39, P = 0.03) and lower education (OR = 3.03, 95% CI = 1.21 to 7.56, P = 0.01). CONCLUSION: The study findings suggest that chemical warfare victims with ophthalmologic complications suffer from poor health related quality of life. It seems that the need for provision of health and support for this population is urgent. In addition, further research is necessary to measure health related quality of life in victims with different types of disabilities in order to support and enhance quality of life among this population.

Abstract: Cultural adaptation and validation of the Persian version of the Arthritis Measurement Scales 2-Short Form (AIMS2-SF). The translation and cultural adaptation of the original questionnaire was carried out in accordance with published guidelines. Three hundred and fifty consecutive Persian-speaking patients with rheumatoid arthritis (RA) were asked to complete the AIMS2-SF, the Short Form Health Survey (SF-36), and four visual analog scales (VAS) for pain, joint stiffness, and patient's and physician's global assessment to test convergent validity. In addition, 90 randomly selected patients were asked to complete the questionnaire 48 h later for the second time. Moderate to high correlation were found between the AIMS2-SF and subscales of the SF-36 and VAS for pain, morning stiffness, and patient's and physician's global assessment. Cronbach's alpha coefficient for the Persian AIMS2-SF scales ranged from 0.74 to 0.89. The Persian AIMS2-SF scales showed excellent test-retest reliability with Intraclass Correlation Coefficient ranging from 0.83-0.93 (p < 0.01). The results of the present study showed that the Persian AIMS2-SF has reasonably good convergent validity, internal consistency, and test-retest reliability in patients with RA. It can now be applied in clinical settings and future outcome studies in Iran.

Abstract: INTRODUCTION: Differential item functioning (DIF) analyses can be used to explore translation, cultural, gender or other differences in the performance of quality of life (QoL) instruments. These analyses are commonly performed using "baseline" or pretreatment data. We previously reported DIF analyses to examine the pattern of item responses for translations of the European Organisation for Research and Treatment of Cancer (EORTC) QLQ-C30 QoL instrument, using only data collected prior to cancer treatment. We now compare the consistency of these results with similar analyses of on-treatment and off-treatment assessments and explore whether item relationships differ from those at baseline. METHODS: Logistic regression DIF analyses were used to examine the translation of each item in each multi-item scale at the three time points, after controlling for the overall scale score and other covariates. The consistency of results at the three time points was explored. RESULTS: For most EORTC QLQ-C30 subscales, the DIF results were very consistent across the three time points. Results for the Nausea and Vomiting scale varied the most across assessments. DISCUSSION: The results indicated that DIF analyses were stable across each time point and that the same DIF effects were usually found regardless of the treatment status of the respondent.

Abstract: The translation, cultural adaptation and validation of the Persian version of the Western Ontario Rotator Cuff Index (WORC) were carried out in accordance with published guidelines. One hundred fifty consecutive patients with rotator cuff disorders completed the Persian WORC, the Disabilities of the Arm, Shoulder and Hand (DASH) outcome measure, the Short Form Health Survey (SF-36) and visual analog scale (VAS) to test convergent validity. Forty-five randomly selected patients completed the WORC 48 h later for the second time. High internal validity and discriminatory power of the WORC scales were found. Cronbach's alpha coefficient for the Persian WORC ranged from 0.85 to 0.92. The Persian WORC showed excellent test-retest reliability, with intraclass correlation coefficient ranging from 0.88 to 0.94 (P < 0.01). The Pearson's correlation coefficient between the Persian WORC total score and the DASH, the VAS and the SF-36 subscales was -0.76, -0.62 and 0.43 to 0.69, respectively (P < 0.001), indicating a good convergent validity. The results show that the Persian WORC is a reliable and valid instrument to measure health-related quality of life in Persian-speaking patients with rotator cuff disorders in Iran.

Abstract: BACKGROUND: The 12-item Short Form Health Survey (SF-12) as a shorter alternative of the SF-36 is largely used in health outcomes surveys. The aim of this study was to validate the SF-12 in Iran. METHODS: A random sample of the general population aged 15 years and over living in Tehran, Iran completed the SF-12. Reliability was estimated using internal consistency and validity was assessed using known groups comparison and convergent validity. In addition, the factor structure of the questionnaire was extracted by performing both exploratory factor analysis (EFA) and confirmatory factor analysis (CFA). RESULTS: In all, 5587 individuals were studied (2721 male and 2866 female). The mean age and formal education of the respondents were 35.1 (SD = 15.4) and 10.2 (SD = 4.4) years respectively. The results showed satisfactory internal consistency for both summary measures, that are the Physical Component Summary (PCS) and the Mental Component Summary (MCS); Cronbach's alpha for PCS-12 and MCS-12 was 0.73 and 0.72, respectively. Known-groups comparison showed that the SF-12 discriminated well between men and women and those who differed in age and educational status (P < 0.001). In addition, correlations between the SF-12 scales and single items showed that the physical functioning, role physical, bodily pain and general health subscales correlated higher with the PCS-12 score, while the vitality, social functioning, role emotional and mental health subscales more correlated with the MCS-12 score lending support to its good convergent validity. Finally the principal component analysis indicated a two-factor structure (physical and mental health) that jointly accounted for 57.8% of the variance. The confirmatory factory analysis also indicated a good fit to the data for the two-latent structure (physical and mental health). CONCLUSION: In general the findings suggest that the SF-12 is a reliable and valid measure of health related quality of life among Iranian population. However, further studies are needed to establish stronger psychometric properties for this alternative form of the SF-36 Health Survey in Iran.

Abstract: OBJECTIVE: Several factors can influence the quality of life in patients with coronary artery disease (CAD). The goal of this research was to measure quality of life in opium-addicted patients with CAD in order to assess the effect of CAD risk factors on their quality of life. METHOD: The WHOQOL-BREF questionnaire was completed through interviews with 275 patients who underwent isolated coronary artery bypass surgery in Tehran Heart Centre between May and September 2006. RESULTS: No significant differences were found in the mean scores of the four domains of quality of life between the addicted and non-addicted patients. Furthermore, the evaluation of QOL in the groups with CAD risk factors showed that the mean QOL domains were statistically similar between opium addicted and non-opium addicted patients. In the addicted group, men had a higher psychological health score than women. A previous history of myocardial infarction reduced the psychological score in this group. Also, in the addicted patients with a history of diabetes mellitus, social functioning was better than that of the non-diabetics. CONCLUSIONS: The different domains of quality of life in our opium-addicted and non-addicted patients with CAD were similar; and among all the major risk factors for coronary artery disease, only female gender and a previous history of myocardial infarction could influence quality of life in the opium-addicted patients.

Abstract: BACKGROUND: Caesarean section might increase the incidence of surgical interventions and problems resulting from hospitalization and thus affecting quality of life in women after delivery. This study aimed to compare quality of life in women after normal delivery and caesarean section. METHODS: This was a prospective study. A sample of women with normal delivery and caesarean section from 5 health care centers in Isfahan, Iran were entered into the study. Quality of life was measured using the SF-36 at two points in time (time 1: 6 to 8 weeks after delivery; time 2: 12 to 14 weeks after delivery). Data were analyzed to compare quality of life in the two study groups. RESULTS: In all 100 women were interviewed (50 with normal delivery and 50 with caesarean section). Postnatal quality of life in both groups was improved from time 1 to time 2. However, comparing the mean scores between the normal and caesarean delivery groups the results showed that in general the normal vaginal delivery group had a better quality of life for almost all subscales in both assessment times. The differences were significant for vitality (mean score 62.9 vs. 54.4 P = 0.03) and mental health (mean score 75.1 vs. 66.7, P = 0.03) at first assessment and for physical functioning (mean score 88.4 vs. 81.5, P = 0.03) at second evaluation. However, comparing the findings within each group the analysis showed that the normal vaginal delivery group improved more on physical health related quality of life while the caesarean section group improved more on mental health related quality of life. CONCLUSION: Although the study did not show a clear cut benefit in favor of either methods of delivery that are normal vaginal delivery or caesarean section, the findings suggest that normal vaginal delivery might lead to a better quality of life especially resulting in a superior physical health. Indeed in the absence of medical indications normal vaginal delivery might be better to be considered as the first priority in term pregnancy.

Abstract: BACKGROUND: The Brief Fear of Negative Evaluation Scale (BFNE) is a commonly used instrument to measure social anxiety. This study aimed to translate and to test the reliability and validity of the BFNE in Iran. METHODS: The English language version of the BFNE was translated into Persian (Iranian language) and was used in this study. The questionnaire was administered to a consecutive sample of 235 students with (n = 33, clinical group) and without social phobia (n = 202, non-clinical group). In addition to the BFNE, two standard instruments were used to measure social phobia severity: the Social Phobia Inventory (SPIN), and the Social Interaction Anxiety Scale (SIAS). All participants completed a brief background information questionnaire, the SPIN, the SIAS and the BFNE scales. Statistical analysis was performed to test the reliability and validity of the BFNE. RESULTS: In all 235 students were studied (111 male and 124 female). The mean age for non-clinical group was 22.2 (SD = 2.1) years and for clinical sample it was 22.4 (SD = 1.8) years. Cronbach's alpha coefficient (to test reliability) was acceptable for both non-clinical and clinical samples (alpha = 0.90 and 0.82 respectively). In addition, 3-week test-retest reliability was performed in non-clinical sample and the intraclass correlation coefficient (ICC) was quite high (ICC = 0.71). Validity as performed using convergent and discriminant validity showed satisfactory results. The questionnaire correlated well with established measures of social phobia such as the SPIN (r = 0.43, p < 0.001) and the SIAS (r = 0.54, p < 0.001). Also the BFNE discriminated well between men and women with and without social phobia in the expected direction. Factor analysis supported a two-factor solution corresponding to positive and reverse-worded items. CONCLUSION: This validation study of the Iranian version of BFNE proved that it is an acceptable, reliable and valid measure of social phobia. However, since the scale showed a two-factor structure and this does not confirm to the theoretical basis for the BFNE, thus we suggest the use of the BFNE-II when it becomes available in Iran. The validation study of the BFNE-II is in progress.

Abstract: OBJECTIVE: The objective of this study was to ascertain the reliability and predictive power of the World Health Organization's Quality of Life Questionnaire (WHOQOL-BREF) and Short Form 36 Health Survey questionnaire (SF-36) in coronary artery disease patients. METHODS: Between May and September 2006, patients with coronary artery disease hospitalized in Tehran Heart Center were divided randomly into two groups of 268 patients (for assessment of QOL with the SF-36 questionnaire) and 275 patients (for assessment of QOL with the WHOQOL-BREF questionnaire). Cronbach's alpha coefficient was used to test reliability of the two questionnaires and a value of 0.7 or higher was considered satisfactory. RESULTS: For the SF-36 and the WHOQOL-BREF questionnaires, Cronbach's alpha was 0.825 and 0.701, respectively, both of which exceeded 0.7. In SF-36 questionnaire, with the deletion of four items in the scales of mental health (1), role limitation - physical (16), and bodily pain (19), Cronbach's alpha was significantly increased. Also, in the BREF questionnaire, deletion of each of items 3, 4, 8, 9, 22, and/or 26 led to an increase in Cronbach's alpha. CONCLUSION: Although the WHOQOL-BREF questionnaire is a reliable tool for the evaluation of QOL in coronary artery disease patients, its reliability was significantly lower than that of the SF-36 questionnaire and thus it can be less applicable than SF-36 for this purpose.

Abstract: BACKGROUND: The purpose of this study was to examine the effect of a 10-week exercise therapy regimen on activities of daily living (ADL) and perceived health status in patients with Parkinson disease. METHODS: Twenty-four Parkinson's disease patients entered into the study. Participants were allocated into the experimental (n = 12) or control group (n = 12). ADL was assessed using the Short Parkinson Evaluation Scale/Scale for Outcomes in Parkinson Disease (SPES/SCOPA) and perceived health status was measured using the Parkinson's Disease Quality of Life (PDQL) questionnaire. Patients in the experimental group received pharmacological therapy plus a 1-hour exercise therapy session 4 times a week, while patients in the control group received pharmacological therapy only. The Mann-Whitney U test was used for comparison. RESULTS: The mean age of participants was 59.8 (SD = 3.0) and 58.2 (SD = 3.4) years in the experimental and control groups, respectively. The median Hoehn and Yahr stage was 3.0 for both groups. There were no significant differences in all subscales and overall scores between two groups at baseline. However, after the intervention, except for the emotional functioning (P = 0.27), there were significant differences between the two groups for Parkinson symptoms, systemic symptoms, social functioning, and overall scores of the PDQL (all P values < 0.05), and the ADL (P = 0.01) indicating that quality of life was improved in the experimental group. CONCLUSION: The findings from this small scale quasi-randomised trial showed that exercise therapy was effective in improving activities of daily living and perceived health status in patients with Parkinson's disease. Indeed, exercise therapy could be offered to patients with Parkinson disease, considering that it is low in cost and usually has no negative side effects. TRIAL REGISTRATION: Current Controlled Trials ISRCTN98825027.

Abstract: BACKGROUND: Disease and treatment related events, can adversely affect the quality of life of patients with cancer. The purpose of this study was to translate and validate a gastric cancer specific health related quality of life questionnaire (EORTC QLQ-STO22) for Iranian patients suffering from gastric cancer. METHODS: Forward-backward procedure was applied to translate the English language version of the EORTC QLQ-STO22 into Persian (Iranian language). Then, the questionnaire and the EORTC core quality of life instrument (QLQ-C30) were administered to a sample of patients with confirmed diagnosis of gastric cancer. All patients filled in questionnaires before and after one month of treatment. Patients were divided into two groups based on intension of treatment (curative vs. palliative). Reliability and validity of the module was tested by internal consistency and known group comparisons, respectively. RESULTS: In all, 105 patients were entered into the study. Cronbach's alpha for multi-item scales (to test reliability) ranged from 0.54 to 0.87. The questionnaire discriminated well between clinically distinct subgroups of patients both before and after treatment lending support to its convergent and clinical validity. CONCLUSION: Overall, the Iranian version of the EORTC QLQ-STO22 demonstrated a good reliability and clinical validity to support its use in combination with core questionnaire in outcome studies of gastric cancer in Iran. However, using the QLQ-STO22 in a wide range of Iranian patients with gastric cancer should allow further confirmation for its psychometric properties.

Abstract: Purpose. To translate and validate the Persian version of the Arthritis Measurement Scales 2-Short Form (AIMS2-SF) in patients with osteoarthritis (OA) of the knee. Method. The translation and cultural adaptation of the original questionnaire was carried out in accordance with published guidelines. One hundred and fourteen consecutive Persian-speaking patients with OA of the knee were participated in this study. The Short Form Health Survey (SF-36) and visual analogue scales (VAS) for pain and joint stiffness were used to test convergent validity of the Persian AIMS2-SF. In addition, 35 randomly selected patients were asked to complete the questionnaire 3 days later for the second time. Results. The Persian AIMS2-SF showed statistically significant good convergent validity, as assessed with the relevant subscales of the Persian SF-36 and VAS for pain and joint stiffness. Cronbach's alpha coefficient for the Persian AIMS2-SF components ranged from 0.68 to 0.80. The Persian AIMS2-SF components showed good to excellent test-retest reliability with intraclass correlation coefficient ranged from 0.72 to 0.83 (p < 0.01). Conclusions. The Persian version of the AIMS2-SF is a reliable and valid instrument to measure functional disability and health-related quality of life in patients with OA of the knee in Iran. It is simple and easy to use and now can be applied in clinical settings and future outcome studies in Iran.

Abstract: BACKGROUND: The Arthritis Impact Measurement Scales 2 (AIMS2) has not been translated and validated for Persian-speaking patients with osteoarthritis of the knee. This was to provide a validated instrument to measure functional disability and health-related quality of life in patients with osteoarthritis of the knee in Iran. The aim of this study was to culturally adapt and validate the AIMS2 for Persian-speaking patients with osteoarthritis of the knee in Iran. METHODS: A consecutive sample of patients with knee osteoarthritis were asked to complete the AIMS2, the Short Form Health Survey (SF-36) and four visual analog scales for pain, joint stiffness, patient's and physician's global assessment. Internal consistency and convergent validity were applied to examine psychometric properties of the AIMS2. In addition, 30 randomly selected patients were asked to complete the questionnaire two days later for the second time for test-retest reliability. Finally factor structure of the Persian AIMS2 was performed using the principal component factor analysis. RESULTS: In all 230 patients were entered into the study. The mean (SD) age of the participants was 56.9 (8.7) years and the mean (SD) duration of disease was 7.2 (3.5) years. Cronbach's alpha coefficient and intraclass correlation coefficient (ICC) for the Persian AIMS2 scales ranged from 0.74 to 0.92 and 0.85 to 0.96, respectively. The correlation between most of the Persian AIMS2 scales and the physical and mental summary scores of the SF-36 and the visual analogue scales for pain, joint stiffness, patient's and physician's global assessment were statistically significant indicating a good convergent validity (p < 0.05). The results obtained from factor analysis indicated three latent factors that jointly accounted for 67.5% of the total variance. CONCLUSION: The results showed that the Persian AIMS2 had reasonably good internal consistency, test-retest reliability, and convergent validity in patients with osteoarthritis of the knee. It is simple and easy to use and now can be applied in the future studies in Iran. However, its sensitivity to change needs still to be studied.

Abstract: BACKGROUND: Injuries caused by motor vehicle accidents in Middle East countries are among the highest in the world. Several successful interventions preventing road traffic injuries in developed countries have been practiced; however, these interventions have not been tailored to the cultural, behavioral, and environmental milieu of low- and middle-income countries. Scientifically based efforts to understand risk factors for traffic injury in these countries are needed and they must be translated into prevention programs that are well designed and assessed. This qualitative study is designed to delineate motorcycle use among Iranian motorcyclists and identify motivational correlates for risk behaviors that may result in accidental injury and death. METHODS: Focus groups and in-depth interviews were conducted among motorcyclists, motorcycle passengers, and police officers. RESULTS: Seven accident-related risk behaviors were identified: (1) performing stunts, (2) disobeying traffic rules, (3) driving while under the influence of drugs or alcohol, (4) riding without proper skills or qualifications, (5) illegally transporting passengers, (6) illegally transporting cargo, and (7) not wearing a helmet. These behaviors correspond with four main motivational themes for motorcycle-riding that emerged from our data: (1) convenient commuting, (2) occupational transportation, (3) recreation and sensation seeking, and (4) criminal activity. CONCLUSION: This study indicates that Iranian motorcyclists can be categorized into distinct groups according to motivation for motorcycle use. The results of this study indicate that motorcyclist risky behaviors are related to motivational factors. Furthermore, regardless of the motivational factors, disobedience of traffic rules was a common risk behavior among all four motivational groups. The relationship between motivation to ride and associated risk behaviors is important because it begins to build a general framework that will help researchers target specific groups that are most in need of interventions to reduce motorcycle accidents in Iran.

Abstract: INTRODUCTION: Psychological adjustment following cancer occurrence remains a key issue among the survivors. This study aimed to investigate psychological distress in patients with breast cancer following completion of breast cancer treatments and to determine its associated factors. MATERIALS AND METHODS: This was a prospective study of anxiety and depression in breast cancer patients. Anxiety and depression were measured using the Hospital Anxiety and Depression Scale at three points in time: baseline (pre-diagnosis), 3 months after initial treatment and 1 year after completion of treatment (in all 18 months follow-up). At baseline, the questionnaires were administered to all the suspected patients while both patients and the interviewer were blind to the final diagnosis. Socio-demographic and clinical data included age, education, marital status, disease stage and initial treatment. Repeated measure analysis was performed to compare anxiety and depression over the study period. Logistic regression analysis was performed to determine variables that predict anxiety and depression. RESULTS: Altogether 167 patients were diagnosed with breast cancer. The mean age of breast cancer patients was 47.2 (SD = 13.5) years, and the vast majority underwent mastectomy (82.6%). At 18 months follow-up, data for 99 patients were available. The results showed that anxiety and depression improved over the time (P < 0.001) although at 18-month follow-up, 38.4% and 22.2% of the patients presented with severe anxiety and depression, respectively. 'Fatigue' was found to be a risk factor for developing anxiety and depression at 3 months follow-up [odds ratio (OR) = 1.04, 95% Confidence interval (CI) = 1.01-1.07 and OR = 1.04, 95% CI = 1.02-1.07 respectively]. At 18 months follow-up, anxiety was predicted by 'pain' (OR = 1.02, 95% CI = 1.00-1.05), whereas depression was predicted by both 'fatigue' (OR = 1.06, 95% CI = 1.02-1.09) and 'pain' (OR = 1.05, 95% CI = 1.01-1.08). CONCLUSION: Although the findings indicated that the levels of anxiety and depression decreased over time, a significant number of women had elevated anxiety and depression at the 18 months follow-up. This suggests that all women should be routinely screened for psychological distress and that quality cancer care include processes to treat that 30% of women who have elevated psychological distress. In addition, if breast cancer patients indicated that they are suffering from fatigue or pain, these women who are at particular risk should be especially screened.

Abstract: Chronic low back pain (CLBP) often proves resistant to treatment because there are different biological, psychological, and social factors that can affect its treatment. In this study, we explored Iranian women's beliefs regarding the cause of their LBP. Findings are based on four focus groups (N = 24 participants) with LBP patients. Participants articulated their causation beliefs (Explanatory Models) about low back pain through three themes: idioms of distress: stress in women's lives; lack of knowledge resulted in high-risk behaviors; and organic/biomedical. Given the difficultly regarding diagnosis and treatment of CLBP, understanding patients' health beliefs, causation beliefs, and experiences are warranted.

Abstract: BACKGROUND: Pain is said to be one of the most feared and distressing symptoms of cancer and one that disrupts all aspects of life. The purposes of this study were: 1) to compare depression and quality of life among Iranian cancer patients with and without pain; and 2) to determine the relationships between pain beliefs and depression and quality of life. METHOD: A consecutive sample of gastrointestinal cancer patients attending to Tehran Cancer Institute were entered into the study. Three standard instruments were used to measure quality of life (the EORTC QLQ-C30), depression (the HADS) and pain beliefs (the PBPI). RESULTS: A total of 142 hospitalized gastrointestinal cancer patients, 98 with pain and 44 without pain were studied. The main findings of this study were that cancer patients with pain reported significantly lower levels of role functioning, emotional functioning and global quality of life. They also showed higher levels of depression than cancer patients who did not experience pain. Among patients with pain, higher scores on pain permanence and pain consistency were positively and significantly associated with higher depression. Also, higher scores on pain consistency were negatively and significantly associated with global quality of life. CONCLUSION: This study has demonstrated the effect of cancer pain on patients' quality of life and emotional status and has supported the multidimensional notion of the cancer pain experience in cancer patients. Although these data are correlational, they provide additional support for a biopsychosocial model of chronic pain.

Abstract: BACKGROUND: Low birth weight (LBW) is considered as a major multifaceted public health concern. Seventy-two percent of LBW infants are born in Asia. An estimation of 8% LBW infants has been reported for Eastern Mediterranean region including Iran. This study investigated contributory factors of LBW in singleton term births in Tehran, Iran. Tehran is a multicultural metropolitan area and a sample from the general population in Tehran could be regarded as a representative sample of urban population in Iran. METHODS: This was a retrospective study using data from 15 university maternity hospitals in Tehran, Iran. Data on all singleton term births in these hospitals were extracted from case records during a one calendar year. Study variables included: maternal age, maternal educational level, history of LBW deliveries, history of preterm labor, cigarette smoking during pregnancy, number of parities, chronic diseases and residential area (Tehran versus suburbs of Tehran). In order to examine the relationship between LBW and demographic and reproductive variables the adjusted logistic regression analysis was performed. RESULTS: In all, data for 3734 term pregnancies were extracted. The mean age of women was 25.7 (SD = 5.3) years and 5.2% of term births were LBW. In addition to association between LBW and maternal age, significant risk factors for LBW were: history of LBW deliveries [adjusted odds ratio (OR) = 2.53, 95% confidence interval (CI) = 1.06-6.03], smoking during pregnancy (OR = 4.64, 95% CI = 1.97-10.95) and chronic diseases (OR for hypertension = 3.70, 95% CI = 2.25-6.06, OR for others = 2.04, 95% CI = 1.09-3.83). CONCLUSION: The findings indicate that in addition to maternal age, history of LBW deliveries; smoking during pregnancy and chronic diseases are significant determinants of LBW in this population. This is consistent with national and international findings indicating that maternal variables and risk behaviors during pregnancy play important roles on LBW.

Abstract: BACKGROUND: The objective of the current study was to translate and validate the Iranian version of the WHOQOL-BREF. METHODS: A forward-backward translation procedure was followed to develop the Iranian version of the questionnaire. A stratified random sample of individuals aged 18 and over completed the questionnaire in Tehran, Iran. Psychometric properties of the instrument including reliability (internal consistency, and test-retest analysis), validity (known groups' comparison and convergent validity), and items' correlation with their hypothesized domains were assessed. RESULTS: In all 1164 individuals entered into the study. The mean age of the participants was 36.6 (SD = 13.2) years, and the mean years of their formal education was 10.7 (SD = 4.4). In general the questionnaire received well and all domains met the minimum reliability standards (Cronbach's alpha and intra-class correlation > 0.7), except for social relationships (alpha = 0.55). Performing known groups' comparison analysis, the results indicated that the questionnaire discriminated well between subgroups of the study samples differing in their health status. Since the WHOQOL-BREF demonstrated statistically significant correlation with the Iranian version of the SF-36 as expected, the convergent validity of the questionnaire was found to be desirable. Correlation matrix also showed satisfactory results in all domains except for social relationships. CONCLUSION: This study has provided some preliminary evidence of the reliability and validity of the WHOQOL-BREF to be used in Iran, though further research is required to challenge the problems of reliability in one of the dimensions and the instrument's factor structure.

Abstract: STUDY DESIGN: A randomized controlled trial. OBJECTIVE: To examine the effects of the back school program on quality of life in women with chronic low back pain. SUMMARY OF BACKGROUND DATA: There is a controversial debate whether back school program might improve quality of life in back pain patients. This study aimed to address this issue. METHODS: One hundred and two eligible women were randomly allocated into 2 groups. The 2 groups including back school group who received the back school program plus medication (n = 50) and clinic group who received just medication (n = 52) were compared at 4 points in time. Data were collected at baseline and at 3, 6, and 12 months follow-up using the SF-36 questionnaire. Repeated measures analysis was performed to compare quality of life scores in 2 groups. RESULTS: Quality of life scores were significantly different between 2 groups throughout the study (P < 0.0001) indicating a better quality of life among intervention group. CONCLUSION: The back school program might improve the quality of life score in women with chronic low back pain.

Abstract: The purpose of this study was to establish test-retest reliability of measurement procedures for quantifying isokinetic concentric peak torque (PT) at the knee using normalization methods post-stroke. A second aim was to estimate the change required to show clinically significant improvements in knee muscles strength. The isokinetic normalized PT (NPT) values for the knee extensors and flexors were measured in each participant at two different angular velocities during two sessions 1 day apart. Thirty participants with mild to moderate hemiparesis after stroke who were able to walk were tested. The normalized PT measures for the knee muscles of the affected lower extremity were highly reliable (intraclass correlation coefficients ranged from 0.85 to 0.98; p<0.05). Size of relative changes (the percent smallest real difference, SRD%) for extensors NPT (ranged from 22.35% to 25.68%) were lower than flexors NPT (ranged from 74.01% to 76.31%), indicating that the affected isokinetic knee flexors had more random variation than the knee extensors. This study supports the use of isokinetic dynamometers for the assessment of knee muscle strength in participants with chronic mild to moderate post-stroke hemiparesis and to measure clinical improvements. Established measurement error and smallest real differences in normalized PT will aid interpretation of real changes in muscle strength in this clinical population.

Abstract: OBJECTIVE: To investigate whether geographic and cultural factors influence the relationship between the global health status quality of life (QL) scale score of the European Organisation for Research and Treatment of Cancer QLQ-C30 questionnaire and seven other subscales representing fatigue, pain, physical, role, emotional, cognitive, and social functioning. STUDY DESIGN AND SETTING: A large international database of QLQ-C30 responses was assembled. A linear regression model was developed predicting the QL scale score and including interactions between geographical/cultural groupings and the seven other scale scores. RESULTS: The pain subscale appeared to have relatively greater influence and fatigue relatively lower influence for those from other European regions compared with respondents from the UK when predicting overall quality of life (QoL). For Scandinavia physical functioning appeared to contribute relatively less. There was evidence of greater emphasis on cognitive functioning for those from South Asia and Latin America compared with the UK, whereas for those from Islamic countries, the role functioning scale appeared to have less influence and physical and social functioning more influence. CONCLUSION: These results provide evidence that different cultural groups may emphasize different aspects of their QoL. This has implications for studies using QoL questionnaires in international comparisons.

Abstract: BACKGROUND: Many women in Iran have a relatively high body mass index. To investigate whether the condition contributes to excess breast cancer cases, a case-control study was conducted to assess the relationships between anthropometric variables and breast cancer risk in Tehran, Iran. METHODS: All incident cases of breast cancer in the Iranian Centre for Breast Cancer (ICBC) were identified through the case records. Eligible cases were all postmenopausal women with histological confirmed diagnosis of breast cancer during 1996 to year 2000. Controls were randomly selected postmenopausal women attending the ICBC for clinical breast examination during the same period. The body mass index (BMI) was calculated based on weights and heights as measured by the ICBC nursing staff. Both tests for trend and logistic regression analysis were performed to calculate odds ratios and 95% confidence intervals as measures of relative risk. RESULTS: In all, 116 breast cancer cases and 116 controls were studied. There were no significant differences between cases and control with regard to most independent variables studied. However, a significant difference was observed between cases and controls indicating that the mean BMI was higher in cases as compared to controls (P = 0.004). Performing logistic regression analysis while controlling for age, age at menopause, family history of breast cancer and parity, the results showed that women with a BMI in the obese range had a three fold increased risk of breast cancer [odds ratio (OR) = 3.21, 95% confidence interval (CI): 1.15-8.47]. CONCLUSION: The results suggest that obesity in postmenopausal women could increase risk of breast cancer and it merits further investigation in populations such as Iran where it seems that many women are short in height, and have a relatively high body mass index.

Abstract: ABSTRACT: BACKGROUND: The aim of this study was to investigate the relationship between educational level and self-reported health in an Iranian population, in order to provide evidence on social inequalities in health from a country in which such data need to be collected. METHODS: This population-based study was carried out in Tehran, Iran. Individuals aged 15 years and over were interviewed. Self-reported health was measured by asking each individual to respond to the question: "In general how would you describe your health at present?" We used years of formal education as a measure of socioeconomic status and categorized the answers in five levels. Logistic regression analysis was used to estimate odds ratios and 95% confidence intervals indicating the contribution of educational level to self-reported health, adjusting for age, gender, marital status, and chronic diseases. RESULTS: In all, 4163 individuals were interviewed. The mean age of the respondents was 35.1 years (SD = 16.0); 52% were female; the mean duration of formal education was 10.0 years (SD = 4.5); and 31% rated their health 'less than good'. Overall, women rated their health more poorly than men (P < 0.0001), and the findings showed that those with higher education rated their health significantly better than those with lower educational levels after adjusting for the age, gender, marital status and chronic diseases. The odds ratio for having 'less than good' self-rated health in those at the lowest educational level compared with those at the highest was 2.65 (95% CI = 1.88-3.73). CONCLUSION: The findings indicated an inverse relationship between educational level and self-rated health, and that age, gender, and chronic conditions had independent effects on self-reported health status. The findings of this first study from Iran suggest that health inequalities in developing countries such as Iran need to be addressed and policies for tackling the problem should be considered. In this respect, less well-educated people and women should be seen as the first target populations. It seems that although expanding the educational system might help the state to provide people with more educational options, it is also necessary to ensure that equal opportunities and access to quality education are provided for those from lower socioeconomic backgrounds; otherwise the current situation might cost the government more in the long term because of poor health among disadvantaged groups.

Abstract: ABSTRACT: BACKGROUND: Breast cancer remains an important public health problem. This study aimed to investigate about female knowledge of breast cancer and self-reported practice of breast self-examination in Iran. METHODS: This was a population-based survey carried out in Tehran, Iran. Data were collected via a structured questionnaire containing 15 questions on demographic status, history of personal and family breast problems, subjective knowledge about breast cancer covering its symptoms, the screening methods and practice of breast self-examination (BSE). A trained female nurse interviewed each respondent. Analysis included descriptive statistics and the Chi-squared test where necessary. RESULTS: A total of 1402 women were interviewed. The mean age of respondents was 43.4 (SD = 14.4) years; most were married (85%), and without any personal (94%) and family history (90%) of breast problems. It was found that 64% of the respondents were familiar with breast cancer and 61% (n = 851) believed that 'the disease is relatively common among women in Iran'. Most women (44%) perceived a painless mass as a breast cancer symptom. Overall, 61% of the respondents stated that they knew about breast cancer screening programs and most indicated that electronic media (television 34% and radio 14%) were their source of information. Only 17% of women said that 'they were conducting regular breast self-examination'. The main reason for women not doing breast self-examination was due to the fact that they did not know how to do it (64%). The findings indicated that performing breast self-examination is significantly related to: age, marital status, education, knowledge of breast cancer and knowledge about breast cancer screening programs (p < 0.05), but not to personal (P = 0.2) and family (P = 0.7) history of breast problems. CONCLUSION: This descriptive study provides useful information that could be utilized by both researchers and those involved in public health programmes. The findings indicated that the women awareness of breast cancer warning signs (painless lump, retraction of nipple, and bloody discharge) and effective screening methods i.e. clinical examination, and mammography were very inadequate. Thus, health education programmes to rectify the lack of women awareness is urgently needed. Indeed the focus of primary health care providers should be to raise awareness about breast care among women and to encourage them to report any unusual changes in their breasts to their family or care physicians.

Abstract: OBJECTIVE: Improving the quality of life (QoL) in patients with coronary artery disease (CAD) requires the determination of the risk factors that have an impact on physical functioning and mental health.The present study sought to determine the risk factors influencing QoL in patients with CAD and to assess the relationship between preoperative QoL and early outcome of CABG. METHODS AND RESULTS: The SF-36 questionnaire was completed through interviews with 275 consecutive patients who underwent isolated CABG in the Tehran Heart Centre between May and September 2006.The present study measured the two scores of physical and psychological component summary scores and assessed their relationships with preoperative characteristics and postoperative complications.The mean scores of physical and psychological components were 65.78 +/- 24.13 and 67.72 +/- 20.55, respectively. Diabetes mellitus (P = 0.007), family history of CAD (P = 0.032), low education level (P = 0.015), high Euroscore (P = 0.022), and high functional class (P <0.001) were the main predictors for the low physical score of QoL. In addition, female gender was associated with a low QoL psychological score (P <0.001). However, the elderly patients had a higher psychological score in comparison with the younger ones (P = 0.032). No relationship between the studied postoperative complications and preoperative psychological and physical scores was found. CONCLUSIONS: Female gender and lower age show specific influences on the patients' mental health. Our findings also indicate a major direct influence of general risk factors for CAD and education level on CAD patients' physical functioning before CABG. Nonetheless, preoperative QoL does not influence the postoperative complications.

Abstract: BACKGROUND: Measuring quality of life in breast cancer patients is of importance in assessing treatment outcomes. This study examined the impact of breast cancer diagnosis and its treatment on quality of life of women with breast cancer. METHODS: This was a prospective study of quality of life in breast cancer patients. Quality of life was measured using the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire (EORTC QLQ-C30) and its breast cancer supplementary measure (QLQ-BR23) at three points in time: baseline (pre diagnosis), three months after initial treatment and one year after completion of treatment (in all 18 months follow-up). At baseline the questionnaires were administered to all suspected identified patients while both patients and the interviewer were blind to the final diagnosis. Socio-demographic and clinical data included: age, education, marital status, disease stage and initial treatment. Repeated measure analysis was performed to compare quality of life differences over the time. RESULTS: In all, 167 patients diagnosed with breast cancer. The mean age of breast cancer patients was 47.2 (SD = 13.5) years and the vast majority (82.6%) underwent mastectomy. At eighteen months follow-up data for 99 patients were available for analysis. The results showed there were significant differences in patients' functioning and global quality of life at three points in time (P < 0.001). Although there were deteriorations in patients' scores for body image and sexual functioning, there were significant improvements for breast symptoms, systematic therapy side effects and patients' future perspective (P < 0.05). CONCLUSION: The findings suggest that overall breast cancer patients perceived benefit from their cancer treatment in long-term. However, patients reported problems with global quality of life, pain, arm symptoms and body image even after 18 months following their treatments. In addition, most of the functional scores did not improve.

Abstract: BACKGROUND: Infertile couples might experience psychological distress and suffer from impaired health-related quality of life. This study aimed to examine health-related quality of life in infertile couples receiving either in-vitro fertilization (IVF) or intracytoplasmic sperm injection (ICSI) treatment. METHODS: This was a cross-sectional study of quality of life in infertile couples attending to Vali-e-Asr Reproductive Health Research Center or Royan Institute for either IVF or ICSI treatment in Tehran, Iran. Health-related quality of life was assessed using the Short Form Health Survey (SF-36). Patients' demographic and clinical characteristics were also recorded. Data were analyzed to compare quality of life in infertile women and men and to indicate what variables predict quality of life in infertile couples. RESULTS: In all 514 women and 514 men (n = 1028) were studied. There were significant differences between women and men indicating that male patients had a better health-related quality of life. Also health-related quality of life was found to be better in infertility due to male factor. Performing logistic regression analysis it was found that female gender, and lower educational level were significant predictors of poorer physical health-related quality of life. For mental health-related quality of life in addition to female gender and lower educational level, younger age also was found to be a significant predictor of poorer condition. No significant results were observed for infertility duration or causes of infertility either for physical or mental health-related quality of life. CONCLUSION: The findings suggest that infertility duration or causes of infertility do not have significant effects on health-related quality of life in infertile couples. However, infertile couples, especially less educated younger women, are at risk of a sub-optimal health-related quality of life and they should be provided help and support in order to improve their health-related quality of life.

Abstract: BACKGROUND: As Iran started to experience population ageing, it is important to consider and address the elderly people's needs and concerns, which might have direct impacts on their well-being and quality of life. There have been only a few researches into different aspects of life of the elderly population in Iran including their health-related quality of life. The purpose of this study was to measure health-related quality of life (HRQoL) of elderly Iranians and to identify its some determinant factors. METHODS: This was a cross-sectional survey of a random sample of community residents of Tehran aged 65 years old and over. HRQoL was measured using the Short From Health Survey (SF-36). The study participants were interviewed at their homes. Uni-variate analysis was performed for group comparison and logistic regression analysis conducted to predict quality of life determinants. RESULTS: In all, 400 elderly Iranian were interviewed. The majority of the participants were men (56.5%) and almost half of the participants were illiterate (n = 199, 49.8%). Eighty-five percent of the elderly were living with their family or relatives and about 70% were married. Only 12% of participants evaluated their economic status as being good and most of people had moderate or poor economic status. The mean scores for the SF-36 subscales ranged from 70.0 (SD = 25.9) for physical functioning to 53.5 (SD = 29.1) for bodily pain and in general, the respondents significantly showed better condition on mental component of the SF-36 than its physical component (mean scores 63.8 versus 55.0). Performing uni-variate analysis we found that women reported significantly poorer HRQoL. Multiple logistic regression analysis showed that for the physical component summary score of the SF-36, age, gender, education and economic status were significant determinants of poorer physical health-related quality of life; while for the mental component summary score only gender and economic status were significant determinants of poorer mental health-related quality of life. The analysis suggested that the elderly people's economic status was the most significant predictor of their HRQoL. CONCLUSION: The study findings, although with a small number of participants, indicate that elderly people living in Tehran, Iran suffer from relatively poor HRQoL; particularly elderly women and those with lower education. Indeed to improve quality of life among elderly Iranians much more attention should be paid to all aspects of their life including their health, and economic status.

Abstract: BACKGROUND: Quality of life in patients with breast cancer is an important outcome. This paper presents an extensive overview on the topic ranging from descriptive findings to clinical trials. METHODS: This was a bibliographic review of the literature covering all full publications that appeared in English language biomedical journals between 1974 and 2007. The search strategy included a combination of key words 'quality of life' and 'breast cancer' or 'breast carcinoma' in titles. A total of 971 citations were identified and after exclusion of duplicates, the abstracts of 606 citations were reviewed. Of these, meetings abstracts, editorials, brief commentaries, letters, errata and dissertation abstracts and papers that appeared online and were indexed ahead of publication were also excluded. The remaining 477 papers were examined. The major findings are summarized and presented under several headings: instruments used, validation studies, measurement issues, surgical treatment, systemic therapies, quality of life as predictor of survival, psychological distress, supportive care, symptoms and sexual functioning. RESULTS: Instruments-Several valid instruments were used to measure quality of life in breast cancer patients. The European Organization for Research and Treatment of Cancer Core Cancer Quality of Life Questionnaire (EORTC QLQ-C30) and its breast cancer specific complementary measure (EORTC QLQ-BR23) and the Functional Assessment Chronic Illness Therapy General questionnaire (FACIT-G) and its breast cancer module (FACIT-B) were found to be the most common and well developed instruments to measure quality of life in breast cancer patients. Surgery-different surgical procedures led to relatively similar results in terms of quality of life assessments, although mastectomy patients compared to conserving surgery patients usually reported a lower body image and sexual functioning. Systemic therapies-almost all studies indicated that breast cancer patients receiving chemotherapy might experience several side-effects and symptoms that negatively affect their quality of life. Adjuvant hormonal therapies also were found to have similar negative impact on quality of life, although in general they were associated with improved survival. Quality of life as predictor of survival-similar to known medical factors, quality of life data in metastatic breast cancer patients was found to be prognostic and predictive of survival time. Psychological distress-anxiety and depression were found to be common among breast cancer patients even years after the disease diagnosis and treatment. Psychological factors also were found to predict subsequent quality of life or even overall survival in breast cancer patients. Supportive care-clinical treatments to control emesis, or interventions such as counseling, providing social support and exercise could improve quality of life. Symptoms-Pain, fatigue, arm morbidity and postmenopausal symptoms were among the most common symptoms reported by breast cancer patients. As recommended, recognition and management of these symptoms is an important issue since such symptoms impair health-related quality of life. Sexual functioning-breast cancer patients especially younger patients suffer from poor sexual functioning that negatively affect quality of life. CONCLUSION: There was quite an extensive body of the literature on quality of life in breast cancer patients. These papers have made a considerable contribution to improving breast cancer care, although their exact benefit was hard to define. However, quality of life data provided scientific evidence for clinical decision-making and conveyed helpful information concerning breast cancer patients' experiences during the course of the disease diagnosis, treatment, disease-free survival time, and recurrences; otherwise finding patient-centered solutions for evidence-based selection of optimal treatments, psychosocial interventions, patient-physician communications, allocation of resources, and indicating research priorities were impossible. It seems that more qualitative research is needed for a better understanding of the topic. In addition, issues related to the disease, its treatment side effects and symptoms, and sexual functioning should receive more attention when studying quality of life in breast cancer patients.

Abstract: BACKGROUND: The Edinburgh Postnatal Depression Scale (EPDS) is a widely used instrument to measure postnatal depression. This study aimed to translate and to test the reliability and validity of the EPDS in Iran. METHODS: The English language version of the EPDS was translated into Persian (Iranian language) and was used in this study. The questionnaire was administered to a consecutive sample of 100 women with normal (n = 50) and caesarean section (n = 50) deliveries at two points in time: 6 to 8 weeks and 12 to 14 weeks after delivery. Statistical analysis was performed to test the reliability and validity of the EPDS. RESULTS: Overall 22% of women at time 1 and 18% at time 2 reported experiencing postpartum depression. In general, the Iranian version of the EPDS was found to be acceptable to almost all women. Cronbach's alpha coefficient (to test reliability) was found to be 0.77 at time 1 and 0.86 at time 2. In addition, test-rest reliability was performed and the intraclass correlation coefficient was found to be 0.80. Validity as performed using known groups comparison showed satisfactory results. The questionnaire discriminated well between sub-groups of women differing in mode of delivery in the expected direction. The factor analysis indicated a three-factor structure that jointly accounted for 58% of the variance. CONCLUSION: This preliminary validation study of the Iranian version of the EPDS proved that it is an acceptable, reliable and valid measure of postnatal depression. It seems that the EPDS not only measures postpartum depression but also may be measuring something more.

Abstract: This study was carried out to examine the factors that predicting the use of complementary and alternative medicine (CAM) among cancer patients in Tehran, Iran. Predicting factors included were patients' demographic characteristics, type of cancer, the knowledge of diagnosis, time since diagnosis, satisfaction with their care physician, fear of recurrence and measures of anxiety, depression and global quality of life. In total, 625 cancer patients were studied, and 35% (n=219) reported that they used or were using CAM. The most commonly used CAM was prayer and spiritual healing (n=178, 75.7% of responses). The results of logistic regression analysis indicated that the use of CAM among cancer patients was associated with the fear of cancer recurrence (OR=2.03, 95% CI=1.45-2.85, P<0.0001) and dissatisfaction with their care physician (OR=1.98, 95% CI=1.36-2.89, P<0.0001). The results indicate that apart from the prayer and spiritual healing, the use of the other common methods of CAM among Iranian cancer patients is unpopular. However, the findings suggest that the use of CAM is more common among cancer patients who suffer from fears, uncertainties and dissatisfaction, and these might be a marker of greater psychological distress in users as compared with non-users.

Abstract: BACKGROUND: Different interventions can reduce the burden of the chronic low back pain. One example is the use of a 'Back School Programme'. This is a brief therapy that uses a health education method to empower participants through a procedure of assessment, education and skill development. This study aimed to evaluate to what extent the programme could improve quality of life in those who suffer from the condition. METHODS: This was a randomized controlled trial. One-hundred and two female patients with low back pain (n = 102) were randomly allocated into two groups, matched in terms of age, weight, education, socioeconomic status, occupation and some aspects of risk behavior. Group 1 (back school group, n = 50) but not group 2 (clinic group, n = 52) received the 'Back School Programme'. Then quality of life using the Short Form Health Survey (SF-36) was assessed at two time points: at baseline and at three months follow-up. The findings were compared both within and between two groups. RESULTS: The 'Back School Programme' was effective in improving patients' quality of life; significant differences were found on all eight subscales of the SF-36 for group 1. In the clinic group (group 2), improvement was observed on three scales (bodily pain, vitality and mental health) but these improvements were less than in group 1. The mean improvement over all eight subscales of the SF-36 was significantly better for the 'Back School Programme' group. CONCLUSION: The 'Back School Programme' is an effective intervention and might improve the quality of life over a period of 3 months in patients who experience chronic low back pain.

Abstract: OBJECTIVE: This study compares telephone consultations with the results of clinical examinations to assess the value and accuracy of telephone consultations for the future planning in a breast cancer clinic in Tehran, Iran. METHODS: In 2500 telephone calls, 800 Symptomatic patients were identified and asked to visit the center for the further investigations by the specialists. The agreement between two observers data were compared by the kappa statistic. RESULTS: Totally 174 patients complied with the recommendation and included in the study. The most common chief complaints of visitors were: breast mass (42%) and breast pain (35%). Kappa statistic showed a very good agreement (K=0.62, P<0.001) between consultants' diagnosis and the specialists findings. This agreement for breast cancer diagnosis, although lower, was also good (K=0.55, P<0.001). CONCLUSION: The study findings indicate that consultants may diagnose and manage some common conditions via telephone, usually following the established protocols. More studies are needed to determine the economic and logistic advantages of telephone consultations. PRACTICE IMPLICATIONS: By assessment of strength and weakness of this service, it is possible to develop an easy to use information system for women who need breast care.

Abstract: Breast cancer is one of the most frequent malignancies among Iranian women, however; the epidemiological aspects of breast cancer among Iranian patients are uncertain. A literature review of the published articles from January 1998 to December 2005 was conducted using different search engines: MEDLINE, Scientific information data base of Academic Center for Education, Culture and Research, and over 2000 issues of 94 Persian medical journals. The headings "Breast Cancer,""Breast Tumor,""Breast Malignancy," and "Breast Carcinoma" were combined with the word "Iran" to execute the search. In all, 85 full papers were reviewed. These findings showed that participants ranged from 15 to 84 years old, with those 40-49 being the most prevalent. The incidence of breast cancer in women was 22 per 100,000. The prevalence in this same population was 120 per 100,000. Stage I was diagnosed in 18%, stage II in 57% and stage III in 25% of the cases. About 72% of the patients were diagnosed with a tumor over 2 cm. Sixty-three percent of the patients had lymph node involvement at the diagnostic time. Infiltrative ductal carcinoma was found to be the most common at 77% and lobular carcinoma the least at 5%. This review indicates that the epidemiological aspects of breast cancer in Iran are relatively well-studied. Shortcomings in study of its clinical aspects are evident and need to be a central part of upcoming investigations.

Abstract: STUDY DESIGN: Cultural translation and psychometric testing. OBJECTIVE: To translate and validate the Iranian versions of the Neck Disability Index (NDI-IR) and the Neck Pain and Disability Scale (NPDS-IR). SUMMARY OF BACKGROUND DATA: The widely used the NDI and the NPDS scales have not been translated and validated for Persian-speaking patients with neck pain. This was to provide a validated instrument to measure functional status in patients with neck pain in Iran. METHODS: The translation and cultural adaptation of the original questionnaires were carried out in accordance with the published guidelines. One hundred and eighty-five patients with neck pain were participated in the study. Patients were asked to complete a questionnaire booklet including the NDI-IR, the NPDS-IR, the Iranian SF-36, and a visual analog scale (VAS) of pain. To carry out the test-retest reliability, 30 randomly selected patients with neck pain were asked to complete the questionnaire booklet 48 hours later for the second time. RESULTS: Cronbach alpha coefficient for the NDI-IR was 0.88 and for the 4 subscales of the NPDS-IR was found to be satisfactory (ranging from 0.74 to 0.94). The NDI-IR and the NPDS-IR subscales showed excellent test-retest reliability (intraclass correlation coefficient ranged from 0.90 to 0.97; P < 0.01). The correlation between the NDI-IR and the NPDS-IR subscales and functional scales of the SF-36 showed desirable results, indicating a good convergent validity (Pearson correlation coefficients ranged from -0.31 to -0.70). The correlation between the NDI-IR and the VAS was 0.71 and between the NPDS-IR subscales and the VAS ranged from 0.63 to 0.79 (P < 0.01). CONCLUSION: The Iranian versions of the NDI and NPDS are reliable and valid instruments to measure functional status in Persian-speaking patients with neck pain in Iran. They are simple and easy to use and now can be applied in clinical settings and future outcome studies in Iran and other Persian speaking communities.

Abstract: BACKGROUND: Although elderly Iranian immigrants in Sweden are the largest elderly group born outside Europe, little is known about their health-related quality of life (HRQL). The aim of this study was to examine the association between migration status and HRQL in a comparison of elderly Iranians in Iran, elderly Iranian immigrants in Sweden, and elderly Swedes in Sweden. METHODS: The Short Form Health Survey (SF-36) was administered to a total of 625 men and women aged 60-84 years to collect HRQL information on elderly Iranians in Sweden (n = 176) and elderly Iranians in Iran (n = 298). A Swedish control group (n = 151) was also randomly selected from the general population. Multiple linear regression procedures were applied to analyze data while adjusting for age, which was categorized into 60-69, and 70-84 years, and education. RESULTS: Iranian women in Sweden with shorter times of residence scored lower on vitality (beta-coefficient = -7.9, 95% CI = -14.3 to -1.5) compared with other women in this study. The lower vitality dimension score remained nearly unchanged in the main model (beta-coefficient = -7.3, 95% CI = -13.7 to -0.9). A longer period of residence in Sweden had a positive association with social functioning (beta-coefficient = 14.1, 95% CI = 3.1-25.1) and role limitation due to emotional problems (beta-coefficient = 18.3, 95% CI = 1.4-35.2) among elderly Iranian women. In general, the Swedish subsample scores higher on all dimensions of the SF-36 among women and in six out of eight among men in relation to the rest of the subsamples. CONCLUSION: The HRQL of elderly Iranians in Sweden was more like that of their countrymen in Iran than that of Swedes, who reported a better HRQL than Iranians in this study. However, length of time since migration to Sweden is not associated with poorer HRQL among elderly Iranians. The association varied, however, with sex. Elderly Iranian women showed an increase in two of eight dimensions of the SF-36 with additional years in Sweden, whereas, among elderly Iranian men, additional years in Sweden were not associated with HRQL.

Abstract: BACKGROUND: Gastrointestinal cancer is the first leading cause of cancer related deaths in men and the second among women in Iran. An investigation was carried out to examine anxiety and depression in this group of patients and to investigate whether the knowledge of cancer diagnosis affect their psychological distress. METHODS: This was a cross sectional study of anxiety and depression in patients with gastrointestinal cancer attending to the Tehran Cancer Institute. Anxiety and depression was measured using the Hospital Anxiety and Depression Scale (HADS). This is a widely used valid questionnaire to measure psychological distress in cancer patients. Demographic and clinical data also were collected to examine anxiety and depression in sub-group of patients especially in those who knew their cancer diagnosis and those who did not. RESULTS: In all 142 patients were studied. The mean age of patients was 54.1 (SD = 14.8), 56% were male, 52% did not know their cancer diagnosis, and their diagnosis was related to esophagus (29%), stomach (30%), small intestine (3%), colon (22%) and rectum (16%). The mean anxiety score was 7.6 (SD = 4.5) and for the depression this was 8.4 (SD = 3.8). Overall 47.2% and 57% of patients scored high on both anxiety and depression. There were no significant differences between gender, educational level, marital status, cancer site and anxiety and depression scores whereas those who knew their diagnosis showed a significant higher degree of psychological distress [mean (SD) anxiety score: knew diagnosis 9.1 (4.2) vs. 6.3 (4.4) did not know diagnosis, P < 0.001; mean (SD) depression score: knew diagnosis 9.1 (4.1) vs. 7.9 (3.6) did not know diagnosis, P = 0.05]. Performing logistic regression analysis while controlling for demographic and clinical variables studied the results indicated that those who knew their cancer diagnosis showed a significant higher risk of anxiety [OR: 2.7, 95% CI: 1.1-6.8] and depression [OR: 2.8, 95% CI: 1.1-7.2]. CONCLUSION: Psychological distress was higher in those who knew their cancer diagnosis. It seems that the cultural issues and the way we provide information for cancer patients play important role in their improved or decreased psychological well-being.

Abstract: Bisphosphonate therapy has been shown to significantly reduce the incidence of skeletal complications in patients with myeloma. Several recent reports have described osteonecrosis of the jaw (ONJ) associated with bisphosphonates. These reports mainly demonstrate an association between ONJ and potent i.v. bisphosphonates. We report a case of ONJ in a patient with myeloma, who had only been treated with oral sodium clodronate. While the degree of risk for osteonecrosis in patients taking oral bisphosphonates, such as clodronate, remains uncertain it would be prudent to consider carefully the indications for the use of these agents to minimise the risk of ONJ.

Abstract: OBJECTIVE: A descriptive study for evaluating the variables which influence the quality of life was performed in women with gynecologic cancer undergoing various kinds of treatment. METHODS: The study was based on a chart review of 104 women with gynecologic cancer and analyses of their compiled FACT-G (V4); (Functional Assessment of Cancer Therapy-General) questionnaires. Patients were assessed before and 3 months after treatment.The relationship of a number of biomedical variables with quality of life outcomes was tested. RESULTS: The mean age of patients was 50.13 years. The most involved organ was ovary (42.3%).The mean of socio-familial, emotional, functional well-being and overall quality of life 3 months after the treatment were greater than previously. The mean of physical well-being after 3 months of treatment was lower than before that (p<0.05). There were no statistical difference between the mean of overall quality of life before treatment and that 3 months after treatment for variables such as marital status, qualification, job, parity, co-morbidity diseases, organ involved, and stage of cancer (p>0.05). CONCLUSIONS: More studies must utilize quality of life as a primary endpoint. As gynecologic cancers are usually discovered in late stages, strategies for supportive care need to focus on symptom management.

Abstract: PURPOSE: To translate and test the reliability and validity of a Persian translation of the Refractive Status and Vision Profile (RSVP), a vision-related quality of life questionnaire, in Iran. METHODS: Forward & backward translation, committee review and pilot testing were performed to develop a final Iranian version of the RSVP. Seventy-three consecutive patients with refractive error before or after refractive surgery at the LASIK ward of Farabi Eye Hospital completed the questionnaire. A convenience sample of 14 patients completed the questionnaire twice within one week. Reliability was measured by internal consistency (Cronbach's alpha) and the intraclass correlation coefficient for test-retest reliability. Validity was evaluated by correlation between the different RSVP subscales, known groups comparison analysis, and correlation between the subscales versus global items and traditional clinical measures. RESULTS: Internal consistency was high (Cronbach's alpha : 0.71-0.92; except for the subscale expectations, alpha : 0.6). Test-retest reliability of subscales and the overall RSVP scale, as estimated by the intraclass correlation coefficient, was high except for optical problems and glare. Comparisons between pre- and post-operative groups of patients showed significantly higher (worse) scores for concern, physical/social functioning, and the overall score in the pre-operative group. Almost all subscales showed desirable inter-scale correlations. CONCLUSION: The Iranian version of the RSVP is a reliable and valid measure of vision-related quality of life in patients with refractive error.

Abstract: BACKGROUND: Health related quality of life (HRQOL) is an important outcome after treatment for upper gastrointestinal carcinoma. This study aimed to compare HRQOL in patients with advanced gastric cancer (GC) receiving either a standard or an experimental treatment. METHODS: Seventy-one patients have been treated in Cancer Institute (Tehran, Iran) with docetaxel, cisplatin, 5 FU (TCF) or epirubicin, cisplatin, 5-FU (ECF) and were followed from Jan 2002 to Jan 2005. End points were response rate, HRQOL and survival. HRQOL was assessed using the EORCT QLQ-C30 at baseline and after the third cycle of chemotherapy. RESULTS: The baseline HRQOL scores were comparable between two groups. After treatment improvement was seen in a number of items and domains except for cognitive functioning, and diarrhoea. Pain decreased and physical functioning improved in both groups. However, only the TCF group showed statistically and clinically meaningful improvement in global QOL (P = 0.001). Surgical and pathologic response was better with TCF but there was no difference in survival rate between two groups. CONCLUSION: Docetaxel based treatment (TCF) showed better palliation and improvement of global QOL as compared with epirubicin based treatment (ECF). However, it seems that regardless of treatment offered, effective chemotherapy was the most important factor affecting QOL in these patients.

Abstract: STUDY DESIGN: Cross-cultural translation and psychometric testing were performed. OBJECTIVES: To cross-culturally translate the Oswestry Disability Index (ODI), Roland-Morris Disability Questionnaire (RDQ), and Quebec Back Pain Disability Scale (QDS) into Persian, and then investigate the psychometric properties of the Persian versions produced. SUMMARY OF BACKGROUND DATA: To the authors' knowledge, there is no validated instrument to measure functional status in Persian-speaking patients with low back pain (LBP) in Iran. To our knowledge, the widely used back-specific measures, the ODI, RDQ, and QDS, have not been translated and validated for Persian-speaking patients with LBP. METHODS: The translation and cross-cultural adaptation of the original questionnaires were performed in accordance with published guidelines. A total of 100 patients with chronic LBP were asked to complete a questionnaire booklet (the Persian versions of the ODI, RDQ, QDS, Short Form Health Survey (SF-36), and visual analog scale measure of pain). There were 31 randomly select patients with chronic LBP asked to complete the second questionnaire booklet 24 hours later. RESULTS: The Cronbach-alpha for the ODI, RDQ, and QDS was 0.75, 0.83, and 0.92, respectively. The ODI, RDQ, and QDS showed excellent test-retest reliability (intraclass correlation coefficient = 0.91, 0.86, and 0.86, respectively) (P < 0.01). The correlation among the ODI, RDQ, QDS and physical functioning scales of the SF-36 was -0.66, -0.62, and -0.69, respectively (P < 0.001). The correlation among the ODI, RDQ, and QDS and visual analog scale was 0.54, 0.36, and 0.46, respectively (P < 0.001). CONCLUSIONS: The Persian versions of the ODI, RDQ, and QDS are reliable and valid instruments to measure functional status in Persian-speaking patients with LBP.They are simple and fast scales, and the use of them can be recommended in a clinical setting and future outcome studies in Iran.

Abstract: This was a cross-sectional study to examine the association between anxiety, depression and quality of life and the use of complementary and alternative medicine. Anxiety and depression was measured using the Hospital Anxiety and Depression Scale (HADS), and quality of life was measured using the global quality of life subscale selected from the European Organization for Treatment and Research of Cancer (EORTC) quality of life core questionnaire (QLQ-C30). In all, 177 breast cancer patients were studied, and 32% (n=57) reported that they used or were using complementary medicine. Users and nonusers did not differ significantly in almost all variables studied, with the exception of duration of their diagnosis. The most commonly used complementary medicine was prayer and spiritual healing (n=45, 73.8% of responses). Performing the logistic regression analysis controlling for age, marital status, educational level, knowledge of diagnosis, time since diagnosis, global quality of life, depression, and anxiety scores, the results indicated that the use of complementary medicine among breast cancer patients was associated with sever depression (odds ratio 2.49, 95% CI 1.06-5.89, P 0.04). The other variables studied did not show any significant results. The study findings confirm that the use of complementary medicine is more common among depressed breast cancer patients and might be a marker of greater psychological distress in this group of patients.

Abstract: A population-based study was conducted to investigate about AIDS knowledge and attitudes among the general public in Tehran, Iran. Using a short questionnaire a random sample of 1172 individuals aged between 15 and 65 years were interviewed. The mean age of the respondents was 34.8 (S.D. = 12.9) years, 52% were male and mostly married (70%), and had received secondary education or above (84%). The findings indicated that the respondents had a fairly good to excellent knowledge about AIDS. The correct answers ranged from 53% to about 99%. Also the results showed that the majority of the respondents were strongly agree or agree with the statement that people with AIDS should have social right to study or work (84%) or with the statement that AIDS is a public health problem (98.7%). The majority of the respondents (87%) said that the mass media including radio, television and newspapers were the main source of their information about HIV/AIDS. The findings from this study indicate that although misconception exist among Iranian about AIDS, in general they have fairly good knowledge and have positive attitudes towards AIDS and people with AIDS. Such findings suggest that prevention programs should be encouraged and these might have the potential role to limit the emergence of Iran's HIV/AIDS epidemic.

Abstract: BACKGROUND: There appear to be geographical differences in decisions to perform mastectomy or breast conserving surgery for early-stage breast cancer. This study was carried out to evaluate general surgeons' preferences in breast cancer surgery and to assess the factors predicting cancer practice in Iran. METHODS: A structured questionnaire was mailed to 235 general surgeons chosen from the address list of the Iranian Medical Council. The questionnaire elicited information about the general surgeons' characteristics and about their work experience, posts they have held, number of breast cancer operations performed per year, preferences for mastectomy or breast conserving surgery, and the reasons for these preferences. RESULTS: In all, 83 surgeons returned the completed questionnaire. The results indicated that only 19% of the surgeons routinely performed breast conserving surgery (BCS) and this was significantly associated with their breast cancer case load (P < 0.01). There were no associations between BCS practice and the other variables studied. The most frequent reasons for not performing BCS were uncertainty about conservative therapy results (46%), uncertainty about the quality of available radiotherapy services (32%), and the probability of patients' non-compliance in radiotherapy (32%). CONCLUSION: The findings indicate that Iranian surgeons do not routinely perform BCS as the first and the best treatment modality. Further research is recommended to evaluate patients' outcomes after BCS treatment in Iran, with regard to available radiotherapy facilities and cultural factors (patients' compliance).

Abstract: This was a large population-based study to develop and validate the Iranian version of the Short Form Health Survey (SF-36) for use in health related quality of life assessment in Iran. A culturally comparable questionnaire was developed and pilot tested. Then, the Iranian version of the SF-36 was administered to a random sample of 4163 healthy individuals aged 15 years and over in Tehran. The mean age of the respondents was 35.1 (SD = 16.0) years, 52% were female, mostly married (58%) and the mean years of their formal education was 10.0 (SD = 4.5). Reliability was estimated using the internal consistency and validity was assessed using known groups comparison and convergent validity. In addition factor analysis was performed. The internal consistency (to test reliability) showed that all eight SF-36 scales met the minimum reliability standard, the Cronbach's alpha coefficients ranging from 0.77 to 0.90 with the exception of the vitality scale (alpha = 0.65). Known groups comparison showed that in all scales the SF-36 discriminated between men and women, and old and the young respondents as anticipated (all p values less than 0.05). Convergent validity (to test scaling assumptions) using each item correlation with its hypothesized scale showed satisfactory results (all correlation above 0.40 ranging from 0.58 to 0.95). Factor analysis identified two principal components that jointly accounted for 65.9% of the variance. In general, the Iranian version of the SF-36 performed well and the findings suggest that it is a reliable and valid measure of health related quality of life among the general population.

Abstract: BACKGROUND: An earthquake measuring 6.3 on the Richter scale struck the city of Bam in Iran on the 26th of December 2003 at 5.26 A.M. It was devastating, and left over 40,000 dead and around 30,000 injured. The profound tragedy of thousands killed has caused emotional and psychological trauma for tens of thousands of people who have survived. A study was carried out to assess psychological distress among Bam earthquake survivors and factors associated with severe mental health in those who survived the tragedy. METHODS: This was a population-based study measuring psychological distress among the survivors of Bam earthquake in Iran. Using a multi-stage stratified sampling method a random sample of individuals aged 15 years and over living in Bam were interviewed. Psychological distress was measured using the 12-item General Health Questionnaire (GHQ-12). RESULTS: In all 916 survivors were interviewed. The mean age of the respondents was 32.9 years (SD = 12.4), mostly were males (53%), married (66%) and had secondary school education (50%). Forty-one percent reported they lost 3 to 5 members of their family in the earthquake. In addition the findings showed that 58% of the respondents suffered from severe mental health as measured by the GHQ-12 and this was three times higher than reported psychological distress among the general population. There were significant differences between sub-groups of the study sample with regard to their psychological distress. The results of the logistic regression analysis also indicated that female gender; lower education, unemployment, and loss of family members were associated with severe psychological distress among earthquake victims. CONCLUSION: The study findings indicated that the amount of psychological distress among earthquake survivors was high and there is an urgent need to deliver mental health care to disaster victims in local medical settings and to reduce negative health impacts of the earthquake adequate psychological counseling is needed for those who survived the tragedy.

Abstract: Road traffic accidents are considered to be the second highest cause of mortality in Iran. A study was conducted to describe road-traffic-related mortality data in Iran in a given period. All Iranian mortality data on road traffic accidents between March 1999 and 2000 (one complete Iranian calendar year) were obtained. The main variables studied were deceased's gender, age, education level, status (i.e. driver, car occupant, etc.), cause and place of death. A total of 15?482 individuals died from road traffic accidents in Iran in the study period. A disproportionate number of deceased individuals were male (79%), mostly aged 40 years or less (65%), and who were pedestrians or car occupants (62%). Head injury was the most common cause of road-traffic-related mortality (66%) in males and females of all ages. Following road traffic accidents, 57% of deaths occurred pre-hospital. Head injury is the most common single cause of mortality attributable to road traffic accidents in Iran, and since most deaths occur pre-hospital, it seems many are preventable. To overcome this major public health problem, there is an urgent need to develop a comprehensive injury control policy and strategy in Iran.

Abstract: BACKGROUND: As part of an assessment of quality of life in lung cancer patients an investigation was carried out to examine whether the knowledge of their diagnosis affected their quality of life. METHODS: Every patient in a defined geographical area with a potential diagnosis of lung cancer was interviewed at first consultation and after a definitive treatment has been given. Quality of life was assessed using three standard measures: the Nottingham Health Profile (NHP), the EORTC quality of life questionnaire (QLQ-C30) and its lung cancer supplementary questionnaire (QLQ-LC13). Comparison was made in quality of life scores between patients who knew their cancer diagnosis and those who did not. RESULTS: In all, 129 lung cancer patients were interviewed. Of these, 30 patients (23%) knew and 99 (78%) did not know their cancer diagnosis at the time of baseline assessment. The patient groups were similar in their characteristics except for age (P = 0.04) and cell type (P < 0.0001). Overall, there were no significant differences between these two groups with regard to their scores on the three instruments used. A major finding was that both group scored almost the same on emotional reactions (P = 0.8) and social isolation (P = 1.0) as measured by the NHP, and emotional (P = 0.7) and social functioning (P = 1.0) as measured by the EORTC QLQ-C30. In addition there were no significant differences in patients' symptom scores between those who knew their diagnosis and those who did not, nor did any consistent pattern emerge. The only significant difference was for sleep difficulties (P = 0.02). CONCLUSION: The findings suggest that the knowledge of cancer diagnosis does not affect the way in which patients respond to quality of life questionnaires.

Abstract: A descriptive study was carried out to examine patient satisfaction among women attending the Iranian Centre for Breast Cancer. A specially designed patient satisfaction questionnaire was distributed to all attendees and they were asked to complete the questionnaire. The questionnaire contained items on satisfaction with care organization, physical environment, personnel communication skills, clinical care, and overall satisfaction. In all, 425 women participated in the study. The mean age of women was 40.4 years (SD = 11.6), most were married (81%) and housewives (69%). A vast majority of women were very satisfied or satisfied with physical environment, personnel communication skills, and clinical care received. Eighty-two per cent of respondents were very satisfied or satisfied with the clinic's overall performance. There was a significant agreement between patients' overall satisfaction and satisfaction with physical environment, personnel communication skills, and clinical care. There was greatest agreement between patients' overall satisfaction and satisfaction with examination room (Kappa = 0.21, P < 0.0001) and with physicians' consultation (Kappa = 0.20, P < 0.0001). None of the demographic variables showed any significant association with patients' overall satisfaction. The findings suggest that the physical environment and physicians' style of consultation contribute most to the patients' overall satisfaction.

Abstract: Although controversial, the belief that developing breast cancer may be associated with psychological distress is not uncommon. The present study examined the role of psychological variables in the development of breast cancer in women attending a breast clinic for medical examination in Tehran, Iran. During a three-year period (1997-1999) a trained female nurse interviewed all women attending the Iranian Center for Breast Cancer (ICBC) before a confirmed diagnosis was made (N = 3000). Data were collected on demographic variables (age, education and marital status), known risk factors (age at menarche, age at first time full term pregnancy, family history of breast cancer, menopausal status, and oral contraceptive use), psychological variables, including history of psychiatric medications, depression (depressed mood, hopelessness, and loss of interests and pleasures), anxiety (mental and somatic signs) and two single measures of overall health and quality of life. In all, 243 patients were diagnosed as having breast cancer. A total of 486 patients with benign disease were randomly selected from the original cohort as controls. Univariate and multivariate logistic regression analyses were performed to determine the predictive effect of each factor on the risk of breast cancer. There were no significant differences between cases and controls except for age at menarche (P = 0.007) and family history of breast cancer (P<0.001). With regard to psychological variables studied, the results showed that there were significant differences between cases and controls regarding depression (depressed mood P<0.0001, hopelessness P = 0.001, and loss of interest and pleasures P = 0.001), and anxiety (mental signs P = 0.006). Finally, after performing multiple logistic regression analysis in addition to family history and age at menarche, depressed mood and hopelessness showed significant results (odds ratios of 1.90, and 1.63 respectively). The findings of the present study suggest that in addition to the known risk factors, psychological determinants such as depressed mood may play an important role in etiology of breast cancer and deserve further investigation, especially in different populations.

Abstract: BACKGROUND: Seroma formation is the most frequent postoperative complication after breast cancer surgery. We carried out a study to investigate the effect of various demographic, clinical and therapeutic variables on seroma formation. PATIENTS AND METHODS: A retrospective cross sectional study of patients who underwent surgical therapy for breast cancer with either modified radical mastectomy (MRM) or breast preservation (BP) was carried out. The demographic data and clinical information were extracted from case records. Seroma formation was studied in relation to age, type of surgery, tumor size, nodal involvement, preoperative chemotherapy, surgical instrument (electrocautery or scalpel), use of pressure garment, and duration of drainage. The multiple logistic regression analysis was performed to estimate odds ratios. RESULTS: A total of 158 patients with breast cancer were studied. The mean age of the patients was 46.3 years (SD +/- 11.9). Seventy-three percent underwent modified radical mastectomy and the remaining 27% received breast preservation surgery. Seroma occurred in 35% of patients. In multivariate logistic regression analysis an association of postoperative seroma formation was noted with modified radical mastectomy (OR = 2.83, 95% CI 1.01-7.90, P = 0.04). No other factor studied was found to significantly effect the seroma formation after breast cancer surgery. CONCLUSION: The findings suggest that the type of surgery is a predicting factor for seroma formation in breast cancer patients.

Abstract: BACKGROUND: This study reports data from a survey carried out in the Iranian Center for Breast Cancer (ICBC) to examine whether women read poster displays in waiting rooms and whether they would have any suggestions to improve posters and thus meet their informational needs. METHODS: Five specially designed posters were displayed in waiting rooms in the ICBC. The content of posters was related to risk factors, early detection, signs and symptoms, and prevention of breast cancer. During a 3 month period a self-administered questionnaire was distributed to all attendees and they were asked to complete the questionnaire. RESULTS: Overall, 850 women were given the questionnaire and 777 completed questionnaires (91 per cent) were returned. The mean age of the women was 37.0 years (SD = 10.7) and they mostly had secondary education (47 per cent). In all, 691 women (86 per cent) reported that they had seen the posters and 620 (80 per cent) said that they had read the displays. The vast majority of the women reported that posters were readable (89 per cent) and understandable (80 per cent). However, 25 per cent of the respondents indicated that materials on the displays created more questions rather than answering their questions and some reported that they became upset (26 per cent) or felt anxiety (42 per cent) while reading the posters. Finally, 218 women (28 per cent) had suggestions to improve posters, of whom 110 (50 per cent) believed that the posters should be simpler. CONCLUSION: The study findings suggest that despite the limitations of posters as a means of health communication, their use in public places may be useful but consideration should be given to the content of the poster displays to prevent anxiety.

Abstract: A prospective study was undertaken to examine survival in Iranian breast cancer patients. One hundred and sixty-seven breast cancer patients diagnosed in 1997 were entered into the study and followed up for five years. The mean age of the patients at diagnosis was 47.2 (SD = 13.5), ranging from 24 to 81 years. A total of 39 patients were lost in the follow-up period, leaving 128 for analysis of data. Of these, 79 were alive and 49 were dead after five years. Most patients (61%) presented with advanced disease. Using life table analysis, the overall relative 5-year survival rate was found to be 62% (SE = 0.04). In addition, after adjustment for age at diagnosis, initial treatment (mastectomy, breast conserving surgery, and neo-adjuvant therapy), and disease stage, using Cox's regression model, it was found that receiving neo-adjuvant therapy as the initial treatment was an independent predictor of poorer survival (Hazard ratio = 4.56, 95% CI 2.20-9.44, P<0.0001). The other variables (older age and late stage disease), although associated with high hazards rates, were not significant. The study findings suggest that overall relative survival rate in Iranian breast cancer patients stands between western and eastern European countries and needs to be improved. It seems that early detection and better management using standard guidelines might contribute considerably to improvement of survival in women experiencing breast cancer.

Abstract: A prospective study was conducted to measure quality of life in newly diagnosed lung cancer patients attending a chest clinic in a large teaching and district general hospital in a geographically defined area (northern sector of Glasgow, Scotland). Quality of life was assessed at two points in time, pre-diagnosis (baseline) and 3 months after diagnosis (follow-up) using three standard measures; the Nottingham Health Profile (NHP); the European Organisation for Research and Treatment of Cancer Quality of Life Questionnaire (EORTC QLQ-C30), and its lung cancer supplement (QLQ-LC13). Out of 133 lung cancer patients diagnosed during the study period, 129 patients (97%) were interviewed pre-diagnosis. Of these, only 63% of the patients had an active treatment. Ninety-six patients were alive at follow-up, of whom 82 patients were re-interviewed. Thus, only 82 patients who had complete data were used in the analysis. Comparing patients' pre-diagnosis and follow-up scores on the NHP, only sleep difficulties improved slightly. Patients reported increased perceived health problems of all other characteristics studied (energy, p = 0.0004; physical mobility, p = 0.0008). Similar results were observed on the EORTC questionnaires indicating that patients' functioning and global quality of life had decreased. The only significant improvement after 3 months was seen in patients' cough (p = 0.006). There were marked increases in hair loss (p < 0.0001), constipation (p = 0.007), and sore mouth (p = 0.0004). The findings suggest that patient-centred variables should receive sufficient consideration in the treatment of lung cancer. The study results clearly indicate that information on quality of life contributes to our understanding of patients' experiences of their cancer treatment.

Abstract: A prospective study was designed to investigate the factors predicting fatigue in breast cancer patients using the Cancer Fatigue Scale (CFS) in addition to the Hospital Anxiety and Depression Scale (HADS) and a questionnaire containing items on demographic and clinical data, and measures of patients' physical symptoms. The CFS measures total fatigue score ranging from 0 (lowest level) to 60 (highest level) and contains three subscales namely: physical, affective and cognitive fatigue. The questionnaires were administered to a consecutive sample of breast cancer patients attending the Iranian Center for Breast Cancer either for their treatment or follow-up examination. In all, 112 patients were studied. The mean age of the respondents was 45.7 years (SD11.0). Most had stage II breast cancer (67%) and had completed their initial treatment (45%). The mean total fatigue score of the patients was 18.7 (SD 13.5) and overall 49% reported experiencing fatigue to some degree (from quite a bit to very much). Severe anxiety and depression was reported by 16% and 32%, respectively. The regression analysis revealed that fatigue was predicted by depression ( P=0.003), pain ( P=0.005), current tamoxifen use ( P=0.001), undergoing mastectomy ( P=0.03) and anxiety ( P=0.04). The other variables studied did not emerge as significant predictors of fatigue in the regression analysis. The study findings suggest that in comparison to treatment factors, physical and psychological symptoms have a more important role in cancer-related fatigue and that fatigue should be recognized and managed even before commencing breast cancer treatment.

Abstract: BACKGROUND: As part of a prospective study on quality of life in newly diagnosed lung cancer patients an investigation was carried out to examine whether there were differences among patients' quality of life scores and their socioeconomic status. METHODS: Quality of life was measured at two points in time (baseline and three months after initial treatment) using three standard instruments; the Nottingham Health Profile (NHP), the European Organization for Research and Cancer Treatment Quality of Life Questionnaire (EORTC QLQ-C30) and its lung cancer supplement (QLQ-LC13). Socioeconomic status for each individual patient was derived using Carstairs and Morris Deprivation Category ranging from 1 (least deprived) to 7 (most deprived) on the basis of the postcode sector of their address. RESULTS: In all, 129 lung cancer patients entered into the study. Of these data for 82 patients were complete (at baseline and follow-up). 57% of patients were of lower socioeconomic status and they had more health problems, less functioning, and more symptoms as compared to affluent patients. Of these, physical mobility (P = 0.05), energy (P = 0.01), role functioning (P = 0.04), physical functioning (P = 0.03), and breathlessness (P = 0.02) were significant at baseline. However, at follow-up assessment there was no significant difference between patient groups nor did any consistent pattern emerge. CONCLUSION: At baseline assessment patients of lower socioeconomic status showed lower health related quality of life. Since there was no clear trend at follow-up assessment this suggests that patients from different socioeconomic status responded to treatment similarly. In general, the findings suggest that quality of life is not only the outcome of the disease and its treatment, but is also highly dependent on each patients' socioeconomic characteristics.

Abstract: BACKGROUND: The objective of this study was to translate and to test the reliability and validity of the 12-item General Health Questionnaire (GHQ-12) in Iran. METHODS: Using a standard 'forward-backward' translation procedure, the English language version of the questionnaire was translated into Persian (Iranian language). Then a sample of young people aged 18 to 25 years old completed the questionnaire. In addition, a short questionnaire containing demographic questions and a single measure of global quality of life was administered. To test reliability the internal consistency was assessed by Cronbach's alpha coefficient. Validity was performed using convergent validity. Finally, the factor structure of the questionnaire was extracted by performing principal component analysis using oblique factor solution. RESULTS: In all 748 young people entered into the study. The mean age of respondents was 21.1 (SD = 2.1) years. Employing the recommended method of scoring (ranging from 0 to 12), the mean GHQ score was 3.7 (SD = 3.5). Reliability analysis showed satisfactory result (Cronbach's alpha coefficient = 0.87). Convergent validity indicated a significant negative correlation between the GHQ-12 and global quality of life scores as expected (r = -0.56, P < 0.0001). The principal component analysis with oblique rotation solution showed that the GHQ-12 was a measure of psychological morbidity with two-factor structure that jointly accounted for 51% of the variance. CONCLUSION: The study findings showed that the Iranian version of the GHQ-12 has a good structural characteristic and is a reliable and valid instrument that can be used for measuring psychological well being in Iran.

Abstract: BACKGROUND: A descriptive study was conducted in Tehran, Iran, to investigate the beliefs of Muslim women and their practices regarding screening modalities of breast cancer. METHODS: A questionnaire was specially designed and validated to collect data and was completed by 410 Muslim women. RESULTS: A vast majority of women (90 per cent) said that breast self-examination is not against their religious beliefs. With regard to clinical breast examination, although 58 per cent preferred to be examined by a female physician, 47 per cent said that clinical breast examination by a male physician is not against their Islamic beliefs. However, only 6 per cent of respondents performed breast self-examination on a regular basis (monthly). CONCLUSIONS: The study findings suggest that most Muslim women do not perceive breast self-examination as being against their Islamic beliefs and that they believe clinical breast examination by a male physician does not interfere with their religious beliefs.

Abstract: BACKGROUND: A cross sectional study was conducted in Tehran Iran to examine the extent of patient delay and associated factors in the presentation of breast cancer. METHODS: A group of newly diagnosed breast cancer patients were interviewed and were asked about the period from first onset of symptoms to first medical consultation to indicate patient delay. This was studied in relation to patients' age, educational level, marital status, family history of breast cancer, history of benign breast disease, number of children and the nature of the first symptom seen. RESULTS: In all, 190 breast cancer patients were interviewed. Of these, 75% presented to physician within 3 months. Forty-two patients (25%) delayed more than 3 months. In multivariate regression analysis it was found that there was a risk for longer delay in widowed or divorced women (OR 3.7, 95% CI 1.5-9.7), women with a positive family history of breast cancer (OR 2.8, 95% CI 1.1-7.7), and less educated patients (illiterate: OR 5.2, 95% CI 1.5-17.7; primary schooling: OR 4.6, 95% CI 1.4-14.7). Significant associations also were found between delay presentation and the late stage disease (P = 0.01) and bigger tumor size (P = 0.004). CONCLUSION: The findings suggest that one in four women with breast cancer present late and this has significant effect on their disease prognosis. To reduce patient delay health education programs regarding breast cancer should be implemented and target women who are at higher risk of delay.

Abstract: BACKGROUND: The Hospital Anxiety and Depression Scale (HADS) is a widely used instrument to measure psychological morbidity in cancer patients. This study aimed to translate and test the reliability and validity of the Iranian version of the HADS. METHODS: The English language version of the HADS was translated into Persian (Iranian language) and was used in this study. The questionnaire was administered to a consecutive sample of 167 breast cancer patients and statistical analysis was performed to test the reliability and validity of the HADS. RESULTS: In general the Iranian version of the HADS was found to be acceptable to almost all patients (99%). Cronbach's alpha coefficient (to test reliability) has been found to be 0.78 for the HADS anxiety sub-scale and 0.86 for the HADS depression sub-scale. Validity as performed using known groups comparison analysis showed satisfactory results. Both anxiety and depression sub-scales discriminated well between sub-groups of patients differing in clinical status as defined by their disease stage. CONCLUSION: This preliminary validation study of the Iranian version of the HADS proved that it is an acceptable, a reliable and valid measure of psychological distress among cancer patients.

Abstract: Abstract. This study was carried out to examine the status of cancer patient education in Iran. Using the Multinational Association of Supportive Care in Cancer's (MASCC) patient education questionnaire, 310 individuals - a sample of heterogeneous cancer patients ( n=167) and their relatives ( n=143) - were enrolled in the study. The pooled results indicated that only 15% of respondents believed more than 80% of cancer patients were told of their diagnosis. In contrast, 30% of respondents thought less than 20% of patients knew their cancer diagnosis. When asked, "Were you given written materials about (i) cancer, (ii) treatment, and (iii) symptom management", the vast majority of respondents said "No" (91%, 87%, and 87%, respectively). When respondents were asked, "Would you like to learn more about cancer and treatments", 97% said "Yes". Most respondents indicated the need for information on the treatments available (27%) and general information about cancer (20%); most had sought information from health professionals (31%), other cancer patients and friends (29%), and television (22%). Finally, it was found that concern about patients' depression (17%), lack of printed materials (13%), the idea that it was better for patients not to know (12%), and families' requests not to tell the patient (11%) were the most frequently stated barriers to or reasons for restricted cancer patient education. The findings of the study suggest that cancer patient education in Iran is very poor and there is an urgent need to develop policy guidelines on disclosure of cancer diagnoses and patient education.

Abstract: A cross-sectional study was conducted to examine the knowledge of breast cancer, attitudes toward breast self-examination (BSE), and practice of BSE among a sample of female health care workers in Tehran, Iran. Using a purposed questionnaire, a total of 410 women from seven health centers completed the questionnaire. The mean age of the respondents was 32.9 years (SD = 9.5), most (58%) were married, and family history of breast cancer was reported by 11%. Seventy-five percent of the women knew about breast cancer prevalence, but only 27% knew that breast pain is not a symptom of breast cancer. Although 73% of women did know that contact with a relative with breast cancer could not lead to development of breast cancer, the respondents' knowledge of risk factors of breast cancer was not satisfactory. With regard to women's attitudes toward BSE, the majority believed that it is not difficult and time consuming or troublesome (63% and 72%, respectively). Sixty-three percent of the respondents claimed that they know how to examine their breasts, but only 6% performed BSE monthly. The practice of BSE was significantly associated with age (p = 0.01), the level of education (p < 0.0001), personal history of breast problems (p < 0.0001), and knowledge of how to examine the breasts (p < 0.0001). The study findings suggest that the knowledge and behaviors of female health care workers concerning breast cancer is relatively poor and it needs to be improved. Considering the role that health care workers may play in communicating health behaviors to the general public, planning health education interventions for this group of females is essential.

Abstract: A descriptive study was carried out to explore the beliefs and behaviours of Iranian teachers toward breast cancer and breast self-examination (BSE). A 10% random sample of 8000 teachers working in four central regions of Tehran was selected. Data on beliefs and behaviours regarding breast cancer and BSE were collected by means of a structured questionnaire. In all, 578 women participated in the study. The mean age of the respondents was 37.3 y (s.d.=8.8), and most were married (83%). The majority of the respondents believed that 'Like every other woman I am at risk of breast cancer' (67%) and that 'Family history of breast cancer is a risk factor for breast cancer' (59%). However, only 6% of them reported that they are performing BSE on a regular basis. The most common reasons for not doing BSE and not going for clinical examination were lack of knowledge and the belief that it was not necessary (34 and 36%, respectively). Doing BSE was more frequent in married (P<0.00001), and older (P<0.00001) women. Except for those with a positive family history of breast cancer, there was no association between breast cancer beliefs and almost all other variables studied. The findings suggest that although the majority of Iranian teachers seem to be quite knowledgeable about breast cancer, they need more education on breast cancer and BSE. Since teachers' beliefs and behaviours may have an impact on young females, planning training courses for this group of women is essential.

Abstract: BACKGROUND: Iranian breast cancer patients are relatively younger than their Western counterparts. The objective of the present study was to investigate risk factors for breast cancer in Iranian women. METHOD: A case-control study was conducted from April 1997 to April 1998 in Tehran, Iran. Demographical data and risk factor related information were collected using a short structured questionnaire. Odds ratios (ORs) and 95% confidence intervals (CIs) were derived from logistic regression analysis. RESULTS: In all, 286 women with breast cancer and 249 control women were interviewed. In multivariate analysis, only marital status (never married: OR 4.24, 95% CI 1.70-10.57 [P = 0.002]; widowed/divorced: OR 1.71, 95% CI 1.05-2.68 [P = 0.03]) and family history (positive family history of breast cancer: OR 2.95, 95% CI 1.15-7.59 [P = 0.02]) were associated with significantly increased risk for breast cancer. CONCLUSION: The findings of the present study suggest that family history and marital status may have an impact on the incidence of breast cancer in Iranian women.

Abstract: Given that lung cancer is one of the common cancers world-wide, the implications of focusing on quality of life as well as survival require to be understood. We have carried out a study of the relationship between survival and quality of life in patients with lung cancer comparing patients those who lived with those who died within 3 months. The design of the study allowed every patient in a defined geographical area with a potential diagnosis of lung cancer to be studied from first outpatient consultation till after a definitive treatment has been given. Quality of life was measured using three standard questionnaires: the Nottingham Health Profile (NHP), the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire (EORTC QLQ-C30) and its lung cancer supplementary questionnaire (QLQ-LC13) in addition to a study specific questionnaire collecting data on demographic, social, clinical and performance status. The contribution of quality of life in relation to survival adjusted for known prognostic factors was determined using Cox's proportional hazard model. In all 129 lung cancer patients were interviewed, and 96 patients were alive at 3-months follow-up. Only 90 of 96 patients alive at 3-months follow-up were assessable. Descriptive analyses showed that those who were dead had more perceived health problems, greater level of symptoms and significant lower physical and role functioning and global quality of life at presentation. On the other hand, univariate analyses showed that patients' aggregate scores on the NHP, the functioning scores, and global quality of life scores alone were significant predictors of survival (P<0.03, P<0.04, P<0.04, respectively ). The multivariate analyses showed that pre-diagnosis global quality of life was the most significant predictor of the length of survival even after adjusting for known prognostic factors (age, P<0.04; extent of disease, P<0.03; global quality of life, P<0.02), while performance status, sex and weight loss were not. This study confirmed that pre-diagnosis quality of life was a significant predictor of survival. Indeed, pre-diagnosis quality of life should be considered as a clinical status which has to be established by physicians before treatment starts as it is such an important predictor of survival.

Abstract: A prospective study was conducted to assess the long-term impact of attending a support group on the prevalence of psychological morbidity in patients with breast cancer before and after 1-year participation in the Iranian breast cancer support group. Psychological morbidity was measured using the hospital anxiety and depression scale (HADS). In addition, qualitative data were collected to throw some lights on the topic. All current members of the three Iranian breast cancer support groups (n=56) were interviewed. The mean age of patients was 45.4 (S.D.=9.2) years, most were married (n=46, 82%), and 54% of patients (n=30) were diagnosed as having breast cancer from 1 to 5 years ago. While at baseline 16 patients (29%) scored high on the anxiety sub-scale and eight patients (14%) scored high on the depression sub-scale, at follow-up only two patients (2%) were likely experiencing severe anxiety symptoms and there were no patients with probable severely depressed mood. Comparing anxiety and depression at baseline and follow-up, there was a statistically significant difference between baseline and follow-up anxiety (P=0.03) and depression (P=0.008) scores. Analysis of the qualitative data indicated that the group involvement was the most important factor that contributed to the patients' improved psychological well-being. The findings of this prospective study suggest that participation in cancer support groups could have a long-term effect in reducing anxiety and depression in breast cancer survivors.

Abstract: A prospective study was conducted to measure anxiety and depression in Iranian breast cancer patients before and after diagnosis using the Hospital Anxiety and Depression Scale (HADS). The HADS was administered at two points in time: before diagnosis and 3 months after. In all, 168 breast cancer patients were interviewed. While 48% of patients had severe symptoms of anxiety at both baseline and follow-up, more than 60% of patients had no symptoms of depressive illness at pre-and post-diagnosis assessments. Comparing anxiety and depression before diagnosis and after 3 months, there were no significant differences between patients' scores on anxiety (P = 0.42) and depression (P = 0.98) subscales. The results showed that patients with advanced disease and a lower performance status were more anxious and experienced more depression. The study findings suggest that severe symptoms of anxiety are the most frequent symptoms in Iranian breast cancer patients. It seems that during the process of diagnosis and 3 months after psychological morbidity persists in patients who suffer from breast cancer.

Abstract: A retrospective study was carried out in five main General District and Teaching Hospitals in Tehran (18 general surgical wards) to investigate breast cancer in Tehran, Iran. All patients who have had breast pathology during 1985-95 were reviewed. For each patient the following data were extracted from case records sex, age, type of disease (based on ICD-10 and ICD-O), breast cancer pathology, tumor size, lymph node involvement, pathological staging (based on TNM system), type of surgery, mass location and the affected side of breast. In all 3085 records were reviewed. Of these, in 903 cases the final diagnosis was breast cancer. The mean age of breast cancer patients was 47.1 (SD=12.3) y and the age-adjusted analysis showed that the observed number of breast cancer cases in the age group 40-49 was higher than expected (P<0.001). The majority of patients (71%) were patients with infiltrating ductal carcinoma, 70% had advanced disease (Stage III), and in 51% of cases the tumour was more than 5 cm in size. Finally it was found that two-third of patients (76%) underwent modified radical mastectomy. Although this study does not address true incidence, but rather frequency, the findings suggest that the Iranian breast cancer patients are relatively younger than their western counterparts and mostly have locally advanced disease. In terms of breast cancer screening programs, these findings have some implications for public health professionals in Iran.

Abstract: The objective of this study was to test the reliability and validity of the Iranian version of the European Organization for Research and Treatment of Cancer (EORTC) Breast Cancer-Specific Quality of Life Questionnaire (QLQ-BR23). The English-language version of the questionnaire was translated into Persian (Iranian language) and its final form was approved by the EORTC Study Group on Quality of Life and then it was used in this study. The questionnaire was administered at two points in time to a consecutive sample of 168 newly diagnosed breast cancer patients and almost all of them (99%) found the questions easy to understand and acceptable. Cronbach's alpha coefficient for multi-item scales (to test reliability) ranged from 0.63 to 0.95 at baseline and from 0.75 to 0.92 at follow-up administration of the questionnaire. Validity analysis was performed using known-groups' comparison analysis. The results showed that all functional and symptom scales discriminated between sub-groups of patients differing in clinical status as defined by their performance status and disease stage. In addition, all functional and symptoms scales detected change over time, as a function of changes in patients' performance status. In general, the findings of this study indicated that the Iranian version of the EORTC QLQ-BR23 is a reliable and valid supplementary measure of the quality of life in breast cancer patients and can be used in clinical trials and studies of outcome research in oncology.

Abstract: The objective of this study was to test the reliability and validity of the Iranian version of the European Organization for Research and Treatment of Cancer (EORTC) Quality of Life Questionnaire (QLQ-C30). The English-language version of the questionnaire was translated into Persian (Iranian language), and its final form was approved by the EORTC Study Group on Quality of Life before it was used in this study. The questionnaire was administered at two time points to a consecutive sample of 168 newly diagnosed breast cancer patients, and almost all of them (99%) found the questions easy to understand and acceptable. Crohnbach's alpha coefficient for multi-item scales (to test reliability) ranged from 0.48 to 0.95 at baseline and from 0.52 to 0.98 at follow-up administration of the questionnaire. Validity was checked using two methods: inter-scale correlation and known-groups comparison. Almost all inter-scale correlations were statistically significant in the expected direction. Known-groups comparison analysis showed that all functioning and symptom scales discriminated between subgroups of patients differing in clinical status as defined by their performance status and disease stage. In general, the findings of this study indicate that the Iranian version of the EORTC QLQ-C30 is a reliable and valid measure of quality of life in cancer patients and can be used in clinical trials and studies of outcome research in oncology.

Abstract: This descriptive study evaluates a newly established national breast cancer information service in Iran and reports data on the impact of contacting the service. Two instruments were used to collect data: a "call record form" and a "user survey" questionnaire. The call record was filled in after each inquiry, and during 1 year 1,000 forms were completed. The questionnaire was filled in 1 week after each inquiry and was completed for a random sample of 400 callers. Thus, the results are presented in two parts. Analysis of the call record forms (part one) showed that 95% of the callers were female, mostly married (82%) and with secondary or higher education (80%). Most callers reported that they had heard about the service through the mass media (69%). Benign breast diseases, mastalgia and breast masses were the most common subjects of the inquiries (28%, 27%, and 18%, respectively). The majority of callers (77%) said that the main reason for contacting the service was that they wanted more information about breast diseases. Examination of the questionnaires (part two) revealed that 97% of respondents described the service as "useful" or "very useful". The vast majority (80%) perceived the information given as "easy" or "very easy" to understand. When respondents were asked to compare their feelings before and after contacting the service, 86% said that they felt "much more" or "a little more cheerful" and 81% said that they felt "much less" or "a little less worried". Practically all (99%) were satisfied with the overall service provided. The findings indicate that the service is effective in providing information and support for patients, relatives and the general public. The real challenge is how to make the service more widely available, especially to breast cancer patients.

Abstract: A review of the literature was carried out covering the last 25 years (1970 to 1995) by searching through the MEDLINE and manually. The review consists of two companion parts. The first includes studies of quality of life in lung cancer patients in general, while the second part is restricted to defined samples of small and non-small cell lung cancer patients. Excluding non-English and review articles, in total 151 citations were identified and all have been reviewed. Over 50 instruments were used to measure quality of life in lung cancer studies. Of these, the European Organisation for Research and Treatment of Cancer Quality of Life Lung Cancer Questionnaire (EORTC QLQ-LC13) in conjunction with the core cancer questionnaire (QLQ-C30) was found to be the best developed instrument, although there were two other lung cancer-specific measures with good reliability and validity. Several topics in this chapter have been highlighted, including the importance of regularly measuring quality of life in lung cancer patients. Progress and achievements in areas such as performance status as a proxy of quality of life measure, psychological morbidity and symptom distress as predictive factors of quality of survival, and communication problems in quality of life studies of lung cancer patients have been emphasized and their implications in lung cancer care discussed. It is argued that palliation of symptoms, psychosocial interventions, and understanding patients' feelings and concerns all contribute to improving quality of life in lung cancer patients. It is concluded that the future challenge in treatment of lung cancer lies not only in improving the survival, but mainly the patients' quality of life regardless of cell type. Clinical trial and epidemiologic population-based outcome studies are recommended to provide this and to allow a better understanding of the contribution of the socioeconomic characteristics of the patients to their pretreatment and posttreatment quality of life.

Abstract:

Abstract: A descriptive study using two interviewer-administered questionnaires was conducted with the aim of getting to know more about cancer support groups and the people who are using these services. All 71 patients and relatives attending six cancer support groups in the West of Scotland at the time of the investigation were interviewed. They were asked about their satisfaction with care and support, past and current concerns, global health and quality of life, and needs. The majority of participants were married women, middle class, aged 50-65 years old, and were long-time survivors. Fifty-two per cent of cancer patients and 70% of relatives of cancer patients stated that they were very satisfied with support were receiving. Nearly 90% of patients reported that they did not receive any counselling either during their pretreatment from their cancer specialists or latter from a professional counsellor. The "general perceived health" and "global quality of life" among patients and relatives were found to be moderately good or good. Concerns of patients and relatives were studied. Patients reported optimistic changes, while relatives were more negative. Needs assessment indicated that 52% of patients require symptom relief and family support, whereas 53% of relatives need counselling from a professional counsellor and informational support. One-third of patients reported that they had no problems at present, and the rest identified difficulties with home duties, shopping and transportation, and financial problems. The study suggests that there is value in encouraging cancer patients and their relatives to take part in existing cancer support groups. This may help to reduce the burden of disease and the care-burden imposed on families.

Abstract: This paper presents part of a survey which investigated people's response to different approaches to health education campaigns. The main objective of the original study was to find out whether the respondents preferred a fear-inducing campaign or a positive image advertising. Two anti-smoking advertisement produced by the Health Education Board for Scotland (HEBS), one using a fear appeal and the other, using a positive image were examined. A sample of 394 subjects in three age groups took part in the study and they were interviewed by means of a questionnaire. A high proportion in each group, including smokers indicated that they preferred the fear-inducing campaign. To investigate why people prefer this type of image, respondents were asked to explain their reasons. It was found that effective communication requires: (1) reality, (2) clear cut message, (3) simplicity, and (4) thought provoking nature and impact of the message. In addition, with regard to the advertising appeals it was found that both positive image and negative image campaigns could be used to attract attention and consequently communicate with the target population. Finally, the findings of this study in the light of psychosocial theories are discussed, and the Preference Model is proposed as providing a better understanding of the process behind people's preferences.

Abstract: There is a longstanding debate on the contribution of social marketing to public health in general, and to health education and health promotion in particular. This paper presents further discussion from a public health point of view and concludes that priority should be given to health-oriented approaches rather than market-oriented strategies. It is argued that, at best, social marketing is a tool not a solution for health education's and health promotion's problems. To communicate health education messages effectively and efficiently, health needs assessment is recommended as a way forward. It is a public health approach and contains a range of flexible methods in the implementation of health education/promotion programmes.

Abstract: This is the first of a two-part paper on quality of life in cancer patients. This part examines some of the fundamental issues in health-related quality of life measurement with particular attention being given to cancer medicine, thus helping to focus the direction and methodological rigour required in future investigations. Relevant topics are discussed to illustrate the importance of quality of life measures in cancer care. A perspective on the meaning of "outcome' and "quality of life' are presented to demonstrate the controversies that exist in the field. It is concluded that despite methodological limitations, quality of life measures have a potential role in advancing cancer care.

Abstract: A case-control study of quality of life in patients with lung cancer was carried out. The investigation was conducted by means of a series of interviewer-administered instruments. As part of the study, patients' attitudes towards the interviewer-administered questionnaires were studied. Previously we reported that a high proportion of the patients found being interviewed acceptable. The present study firstly examines why patients found being interviewed acceptable and secondly investigates whether there is an association between gender, age, diagnosis, place of interview, patients' overall health status, global quality of life and patients' feelings. Two hundred and thirty-two patients attending an outpatient clinic with either lung cancer or chronic respiratory disease were interviewed by means of a short questionnaire. They were asked to indicate their feelings about interviews, and to explain the reasons why they had their particular feelings. We documented issues on communication between interviewers and patients. These include observations on interviewing cancer patients, interviewing at home, and interviewing in the clinic. Nearly all the patients (96%) indicated that they found being interviewed acceptable. A content analysis of data showed that patients' feelings can be attributed to four major themes: the interview was not disturbing, they felt relaxed and at ease, they liked to talk, and the interview was conversational. There were no significant association between gender, age, diagnosis (cases and controls), place of interview, patients' overall health status and global quality of life and the reasons expressed. Practical experience from interviewing patients at home or in the clinic reveals several issues on communication between interviewer and patients. The study results suggest that apart from communication factors, other parameters such as age, gender, diagnosis, overall health status and quality of life and interview setting do not have significant role in patients' feelings about interviews. If data on quality of life studies are to be collected by interviewers, then proper communication is essential. How to achieve this remains a major question.

Abstract: An investigation was carried out to examine what quality of life means to lung cancer patients. 200 patients with either lung cancer (108) or chronic respiratory disease (92) were interviewed using a short open-ended questionnaire. They were asked to define quality of life in general, identify what they considered to be a good quality of life for themselves and to rank the relative importance attached to each nominated item. A content analysis was carried out and patients' responses were categorised into eight items. These were: ability to do what one wants to do/work, enjoyment of life, family life, financial security, happiness, health, living longer and social life/leisure activities. Of these, health (42%), enjoyment of life (25%) and family life (24%) were the three most nominated items as definition of quality of life in general. Patients perceived a good quality of life for themselves differently. Family life (58%), health (51%) and social life (43%) were found to be the most nominated components of a good quality of life for the patients. Overall, patients ranked family life and health as the first or second most important factors. There were no significant differences between cases and controls. The study results are challenging and serve to remind us that the term quality of life is misused in many studies. Most existing measures do not encompass the wider aspects of quality of life identified here, but rather concentrate on the "health-related" aspects of quality of life. To achieve this, the research into the best ways of measuring and assessing quality of life must continue to seek individual values and preferences and how these can be applied in a simple way in clinical studies.

Abstract: This is the second part of the paper on quality of life in cancer patients which appeared in this journal (Montazeri et al., 1996a). In this part experiences from the treatment of cancer are given and relevant literature is reviewed. Several topics have been covered, including new directions and methods in assessing quality of life. It is argued that in a chronic condition, adding life to years instead of years to life is an important task. Adding years to life may prolong survival, but whether this is to the benefit of patients is debatable. Considering patients' views, their values and preferences may improve the quality of care and at the same time, reduce the psychological distress and physical discomfort in patients with cancer. It is concluded that quality of life measures have considerable potential in this challenging issue.
