BackgroundIrritable bowel syndrome (IBS) is a gastrointestinal disease that is accompanied by pain, diarrhea, constipation and abdominal bloating. Hence, IBS has a major effect on patients’ quality of life.ObjectivesThe present study aimed to examine validity and reliability of the Persian version of the IBS-QOL questionnaire in Iran.Patients and MethodsThe original 34 items of the IBS-QOL were translated from English into Persian through a structured procedure for the translation and cultural adaptation of the original English IBS-QOL into Persian. Ninety one patients who had GI symptoms but did not have any organic diseases (including 70 IBS patients diagnosed by Rome II criteria) were recruited from teaching hospitals Shiraz University in Iran and completed a Persian version of the IBS-QOL along with a Persian version of Room ΙΙ and IBS severity index (IBSSI).ResultsOur findings showed that the IBS-QOL has excellent convergent and acceptable discriminant validity. All domains had Cronbach's alpha greater than 0.7 except health worry. Seventy patients who were diagnosed as IBS by the Room ΙΙ had significantly lower scores in the IBS-QOL than those who were not (FBD) (43.7 ± 20.1 vs. 73.4 ± 14.9, P < 0.01). Age, sex, education or marital status did not affect scores in measuring the quality of life.ConclusionsIn conclusion, the Persian version of the IBS-QOL provided a well-defined measure of QOL in IBS patients with high validity and reliability that is an appropriate measure to use in further IBS clinical studies in Iran.

Background: Social phobia is a pervasive and debilitating disorder, with relatively high prevalence, which is affected by different variables and influences many aspects of human life. This study was carried out with the aim to determine the relationship between social anxiety and personality dimensions among students of

Multiple sclerosis (MS) is defined as an inflammatory, progressive, and autoimmune disease in the central nervous system, recognized by its subsequent demyelination and neurodegeneration. Cognitive disorders are among the most severe problems in patients with MS, affecting their personal and professional life. This study is aimed to evaluate memory and visual learning, visual processing speed, and spatial perception in MS patients based on age, gender, and level of education. This cross-sectional study was carried out on 42 MS patients (based on McDonald’s criteria). The level of disability in patients was assessed using EDSS, and cognitive performance was evaluated by the use of judgment of line orientation (JLO), symbol digit modalities test (SDMT), and revised brief visuospatial memory test (BVMT-R). In this study, patients were within the age range of 20-51 years, 73.8% of which were female, and 61.9% had academic degrees. According to the classes of independent variables (gender, education level), no significant difference was observed in the mean scores of dependent variables (JLO, SDMT, and BVMR-T scores) (P>0.05). In addition, age as a confounding variable had no impact (P>0.05). In addition, gender and level of education had no significant interaction (P>0.05). According to the results of the study, age, gender, and education level had no significant effect on memory and visual learning, visual processing speed, and spatial perception.

Introduction: Regular fruit and vegetable consumption is one of the preventative indicators for the development of obesity, disorders, and diseases. This study aimed to identify the determinants of fruit and vegetable consumption based on social cognitive theory (SCT) among first-grade high school female students. Results: The mean (SD) score daily fruit and vegetable intakes were 3.43 () and 2.30 () units per day, respectively. The results of multiple linear regression analysis showed that environmental factors (β= 0.165, p= 0.009) and behavioral skills (β= 0.152, p= 0.025) have a significant effect on fruit consumption score. Behavioral skills (β= 0.151, p= 0.022) and social support (β= 0.143, p= 0.049) have significant effect on vegetables consumption score, the constructs of SCT explained 71% of the variances in fruit consumption and 9.8% of the variances in vegetable consumption. Mother's job (p= 0.032) and family income (p= 0.024) have a significant effect on fruit and vegetables consumption. Conclusion: Fruit and vegetable intakes were less than the WHO recommended level. Therefore, attention to environmental factors, behavioral skills, and social support is suggested.

Therefore, considering the importance of modifying adolescent girls' physical activity behavior and developing appropriate educational strategies and interventions in this field, this study aimed to investigate the effect of educational intervention based on social cognitive theory (SCT) on adolescent girls' physical activity. Materials & Methods A Quasi-experimental study was conducted among 246 female high schools' Students (124=intervention group and 122=control group) in Rafsanjan (Southern Iran) by random cluster sampling in 2018-19. Demographics variables and valid and reliable questionnaire included the physical activity assessment of the last week and its effective factors based on SCT constructs collected in two stages. Educational interventions were applied in four sessions to students and two sessions to parents, teachers, and school officials. Data analysis was performed using SPSS 16.0, the Mann-Whitney U test, the Wilcoxon test, and the T-test. Findings After executing the educational program, there was a significant difference between the mean scores of the two groups in environmental factors (p=0.027), knowledge (p<0.001), family support (p=0.001), self-efficacy (p=0.001), and self-regulation (p=0.008), comparative between two groups the rates of daily and weekly physical activity increased (p=0.001). Conclusions The implementation of educational programs based on the SCT positively affects promoting physical activity in adolescents.

Background and Objectives: It is important to observe oral health in the high-risk group of pregnant women because of their and their fetal health. The purpose of this study was to identify the predictors of oral health condition among pregnant mothers in Rafsanjan city based on theory of planned behavior in 2016. Materials and Methods: In the present descriptive study, 100 pregnant women in Rafsanjan city were selected by cluster sampling. The data collection tools were a demographic questionnaire, a questionnaire for determining the behavior of oral and dental health and a questionnaire for factors affecting oral and dental health behavior based on the constructs of planned behavior theory. Data were analyzed using Pearson's correlation, one-way variance analysis and multiple linear regression. Results: In multiple linear regression analysis, there was a significant relationship between knowledge factors and behavioral intention and family income and the health behavior score of pregnant women (p<0.05). In total, the constructs of the theory of planned behavior explained 22.7% of the changes in the health behavior score of pregnant women. Conclusion: The results of this study indicated that pregnant women had an undesirable situation in field of health behavior. Therefore, it is recommended that interventions be held based on theory of planned behavior in pregnant women with the aim of improving oral health in health centers.

The eye should have a particular focal length in order to see an object. As there are many things to see, the focal length of the eye must vary because these things are not all at the same distance from the eye. We explore the eye accommodation from a geometrical optics point of view and present our results in this paper; the study includes a description of the accommodation mechanism and a scientific definition of near vision and far vision.
