Background: Following the pandemic of corona disease in Iran and around the world, the most important goal of health policies focused on compliance with prevention behaviors, and its evaluating. One of the most effective model based on social psychology is Health Belief Model that has been employed in many studies as different aspects of preventive behaviors. Objectives: The main purpose was study the relationship between compliance with preventive behaviors of corona disease with health belief model, and predicting the high level and low level of compliance with these behaviors based on health belief model variables. Methods: The present study was a descriptive-correlational study in terms of its method. The statistical population consisted of all adults aged +20 who lived in Tehran. 472 voluntary subjects were selected through online recall method. The instruments of the study included the compliance with preventive behaviors of corona scale (CPBC), and the corona health belief model inventory (CHBM). Both measures were developed and standardized by the researchers. Data were analyzed by using regression analysis. Results: The Means of CPBC in all participants was 3.38 ± 0.83, thereupon two groups were formed accordingly, as high group (4.18±0.17) and low group (1.92±0/28). The findings show that high level of compliance could be predict by severity, benefits; and barriers; and low level of compliance by age, benefits, and barriers. Conclusion: Since preventive behaviors were known as the best way to control of corona virus outbreak, there is a great value of identifying variables that might mitigate or exacerbate compliance could contribute greatly to the development of more effective health planning in Iranian society. Therefore, increase the benefits and reduce the barriers of prevention behaviors could be effective, and consequently, corona virus transmission could be decreased.

Objective: the present study aimed at studying the relationship between job stress and personality traits and also if the effect of job stress on personality traits was moderated by social support. Method: The populations consisted of offshore personnel working in Iranian Offshore Oil Company (IOOC) in Kharg Island. 234 participants using convenience sampling answered three questionnaires (job stress, very brief NEO-form, and perceived social support of family-scale). Four main hypotheses using structural equation analysis were examined. Results: The findings showed a predictive effect between the personality traits and job stress except for openness to experience such that job stress had an increasing effect on neuroticism and a decreasing effect on extraversion, agreeability, and conscientiousness. Social support, on the other hand, as a moderator decreased the effects of job stress on personality traits except for openness to experience, extraversion, and agreeability such that it decreased neuroticism and increased conscientiousness. Conclusion: the results generally revealed the predictive effects of job stress on personality traits and showed that social support, as a buffer, can reduce the effects of job stress on personality traits. The results were discussed based on the existing models on personality changes.

Objective: This study aimed to assess the effectiveness of Cognitive-Behavioral Stress Management (CBSM) on distress tolerance, pain perception, and interleukin-12 (IL-12) in patients with Multiple Sclerosis (MS). Method: The present study was a quasi-experimental design with pretest-posttest and follow-up with control group. The statistical population included all female patients with relapsing-remitting MS who had referred to Neuroscience and Rehabilitation Research Centers of Tehran University of Medical Sciences. 20 patients were selected by convenience sampling and were randomly assigned into experimental (10 patients) and control groups (10 patients). The experimental group received the CBSM. Participants completed scales. To measure IL-12, the Enzyme-Linked Immunosorbent Assay (ELISA) was used. The data were analyzed using multivariate analysis of covariance (MANCOVA) and Bonferroni post-hoc test. Results: CBSM increased the distress tolerance and components of pain perception (perceived influence of important people and doing daily affairs) (p <0.001) and it decreased pain severity and IL-12. Also, these changes remained stable during follow-up. Conclusions: CBSM is an effective to influence on distress tolerance, pain perception, and IL-12 in MS patients.

Abstract The aim of the present study was investigating the effectiveness of Transcranial Direct Current Stimulation (tDCS) on neurocognitive performance in people with mild neurocognitive impairment. Using meta-analysis and integrating the research results, this study has specified the extent of the effect of Transcranial Direct Current Stimulation on improvement of neurocognitive function in people with mild neurocognitive impairment. Method: For meta-analyses Magiran, SID, and Irandoc databases were used to search Persian articles and Science direct, Scopus, and PubMed databases were used to find foreign articles, using ‘MCI’, ‘transcranial direct current stimulation’, tDCS, and ‘mild cognitive impairment’ key words for foreign articles and their Persian equivalents for Persian articles. Of the 29 studies, 11 that were methodologically acceptable were meta-analyzed. The research tool was a meta-analysis checklist. Results: The results of meta-analysis indicated publication bias in the studies. Due to the heterogeneity of the studies, a random effect model was used. The effect of Hedges for the impact of Transcranial Direct Current Stimulation on neurocognitive functions in people with mild neurocognitive impairment was 0.26, which is a large effect. Conclusion: This result shows clinicians can choose transcranial direct current stimulation (tDCS) as effective intervention for patients who suffer from mild cognitive impairments. More investigations are necessary to find the cognitive benefits of using transcranial direct current stimulation in elderly people and other cognitive impaired persons.
