Objective: <span class="fontstyle2">The present study aimed to examine whether the treatment of Internet Gaming Disorder (IGD) in adolescents via Attentional Bias Modification (ABM) improves their health-related quality of life. Method: <span class="fontstyle2">34 adolescents with IGD who were 12-17 years old were randomly assigned to experimental (n = 16) and control (n = 18) groups. The experimental group received ABM, while no interventions were delivered to the control group. Attentional bias, IGD severity, and health-related quality of life were assessed using Modified Stroop Task, Internet Gaming Disorder-20 (IGD-20), and KIDSCREEN-52 questionnaires, respectively. Data from pre-test, posttest, and two months follow-up measurements were analyzed using two-way mixed measures ANOVA and Fisher’s least significant difference (LSD) via SPSS software. Results: <span class="fontstyle2">ABM successfully reduced attentional bias and IGD severity and improved health-related quality of life in adolescents of the experimental group (p < 0.05). These significant changes were observed at post-test and two months follow-up. Meanwhile, no significant change occurred in the control group (p > 0.05). Conclusion: <span class="fontstyle2">It could be concluded that ABM not only reduces the severity of IGD in adolescents, but also improves their health-related quality of life, although further research is required for the understanding of its mechanisms of effects.

Objective: To investigate whether neuroticism and extraversion predicted job-related affective wellbeing of people working under stressful conditions, notably emergency room nurses. Also, to investigate whether perceived job stress mediated the relationship between neuroticism, extraversion and job-related affective well-being. Methods: A cross-sectional survey design was administered to 242 nurses working at an emergency room in Tehran, Iran, recruited through census sampling, including two sub-scales of the NEO Five-Factor Inventory, the Job-Related Affective Well-Being Scale, and the Job Stress Questionnaire. Structural Equation Modelling was deployed for data analysis using SPSS Amos v22.0 and PROCESS macro for SPSS, setting significance threshold at p<.05. Results: Direct and statistically significant effects of neuroticism (β = -.17, p<.005) and extraversion (β = .41, p<.001) on perceived job stress were found, as well as a negative effect of extraversion on job-related affective well-being (β = -.27, p<.001). Perceived job stress was found to negatively predict job-related affective well-being (β = -0.60, p<.001). There was no significant relationship between neuroticism and job-related affective well-being. The mediating effect of perceived job stress was supported (p<.001). Conclusion: Results have theoretical implications for research about the relationship between personality traits and job-related well-being of employees working under stressful conditions. As for practical implications, hospital managers might implement workplace interventions to enhance nurses’ job-related affective well-being and reduce nurses’ job stress. In this context, extraversion and job stress should be understood as psychosocial risk factors, whereas neuroticism should be conceived as a protective factor against job stress.

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: This study aimed to investigate the role of gender moderators in the effectiveness of the Iranian positive youth development package (IPYD) on the components of social-emotional health. Method: For this purpose, in a quasi-experimental design with pre-test, post-test, and follow-up stage, 60 male and female adolescents aged 15-17 years studying in the academic year 2009-2010 were randomly selected in Isfahan. First, all members of the experimental and control groups completed the Zhou and Ee (2012) Emotional-Social Competency Questionnaire, and then the experimental groups were trained with a researcher-made package for 16 sessions of 45 minutes. In the meantime, the control group benefited from the daily training of the school. At the end of the sessions and 40 days later, all groups completed the questionnaire again. Result: Findings showed that the package of the positive development of Iranian adolescence in the short term has led to an increase in the dimensions of social and emotional health in self-awareness, self-management, social awareness, relationship management, and responsible decision-making in both genders, and in long term has caused an increase in all dimensions in girls (p<0.05). Conclusion: It seems that the Iranian adolescent positive development package is a suitable package to strengthen the components of positive development, achieve emotional-social health, and reduce problems and issues in different areas of developmental periods and the subsequent costs for adolescents, their families, and society. Keywords: Development, Emotional health, gender, Positive psychology, Social health.

In this study, we examine the correlation between stock returns of Export-oriented (EOIs) and Import-oriented (IOIs) industries and exchange rates, to derive stock-exchange optimal weights, attempting to manage the risk of investors in the capital market. To do so, the ADCC and DCC models are used. The data consists of the stock return of the listed industries, and the daily exchange rate from 2008 to 2020. The results suggest that EOIs have a dynamic asymmetric conditional correlation, and IOIs have a dynamic symmetric conditional correlation with the exchange rate. Moreover, the results indicate that in both currency crises, the weight of optimal portfolio in all industries except pharmaceuticals, in non-crisis period is over 50% and in the crisis period is less than 50%. Accordingly, and to reduce the risk of the portfolio, in the non-crisis period, investors should invest more than half of a one-Rial portfolio to dollar exchange, and in the crisis period, they should allocate less than half of a one-Rial portfolio to this currency. In case of the currency crisis, it is suggested that investors invest in the stock of basic metals, because this industry is a pioneer in attracting currency crisis and increasing stock value of the industry through future cash flow and replacement value, and reduce the stock of pharmaceuticals and computers in their portfolio, due to attracting negative effects of the exchange market.
