 Objective: Being overweight and obese in adolescence is associated with severe health effects during their lifetime The purpose of this study was to explain the mediating role of self-compassion in the relationship between family cohesion, stress, and quality of life with body mass index in adolescent girls Method: The current research was descriptive-multiple linear regression From among the statistical population of the research, 250 teenage girls were selected as the research sample using a multi-stage cluster sampling method, and finally, after dropping 50 people from the sample group, the data of 200 of them were analyzed. The tools of data collection included the Samani Family Cohesion Questionnaires (2001), Byrne and Mazano Stress (2002) Scale, the World Health Organization Quality of Life (1996) questionnaire, and the NAF Self-compassion (2003) inventory. For data analysis, structural equation modeling was performed using SPSS26 and AMOS24 software. Results: The results showed that the model of body mass index based on the quality of life, family cohesion, and stress with the mediating role of self-compassion has a good fit. It also indicated that family cohesion, stress, and quality of life did not predict body mass index in adolescent girls, But quality of life predicts body mass index in adolescent girls. Conclusion: It seems that self-compassion plays a mediating role in the relationship of body mass index with family cohesion, stress, and quality of life in adolescent girls. 

Introduction: Whenever there is an outbreak of infectious diseases, psychosocial impact has been observed on individual and social levels globally. The psychological and social effects of the COVID-19 epidemic are potential and widespread, which affect people's mental health in the long term.

The statistical population of the research was all the students of Azarbaijan Shahid Madani University, 300 of whom were selected through convenience sampling, and the neuroticism scale was from the short form of the Neo questionnaire, the Cohen et al.'s perceived stress questionnaire, the Kessler psychological distress questionnaire, and the loneliness scale. Social Emotional Assessment for Adults (SELSA-S) was administered to them. Then the obtained data were analyzed using Spss26 and Amos22 software.Results: The results showed that neuroticism is related to psychological distress through loneliness and perceived stress.

This study aims to investigate the impact of job support on job performance, with the mediating role of responsibility and job creativity among the employees of the Education Department in District 1 of Zahedan. This descriptive-correlational research included all 85 employees of the Zahedan District 1 Education Department in 2021 as the statistical population. Given the small population size, all 85 employees were included in the study as the sample. Data were gathered through library and field methods. In the field method, questionnaires on job support by Spooner (2004), job performance by Patterson (1922), responsibility by Gilbreth (2010), and job creativity by Jazi and colleagues (2003) were used. Data analysis was conducted using multivariate regression tests in SPSS-21 software. The results indicated that job support, responsibility, and job creativity have a direct impact on the job performance of employees in the Education Department of District 1, Zahedan. Furthermore, job support indirectly affects job performance through responsibility, and similarly, job support indirectly impacts job performance through job creativity. Thus, job support influences job performance with the mediating roles of responsibility and job creativity among employees in the Zahedan District 1 Education Department.

The aim of this study is to investigate the role of personality traits in prediction of perceived rejection, age feeling, and social exclusion among retirees in Zahedan city. The statistical population of this study includes all retirees in Zahedan city in 2021 – 2022, of which 123 people were selected as samples through the convenience sampling method. To collect data for this study, questionnaires on personality traits, cognitive health, perception of rejection, feeling of aging, and social isolation were used. Pearson correlation coefficient, stepwise multiple regression, and simple linear regression were used to analyze the research data. The results showed that the perception of rejection had a positive and significant correlation with neuroticism (p<.05) and a negative and significant correlation with extraversion, agreeableness, and conscientiousness (p<.01). However, there was no significant correlation between perceived exclusion and openness to experience. According to the results of the study, it can be concluded that personality traits play a significant role in predicting perceived exclusion, feeling of aging, and social isolation in retirees.

The purpose of the research is to analyze the effects of ethical leadership and organizational politics on individual and team creativity, focusing on the mediating role of knowledge hiding. The study is a descriptive-correlational survey and is applied in terms of purpose. The statistical population included employees of selected public organizations in the Eqlid County, totaling 950 individuals. 270 individuals were selected using a non-probability convenience sampling method based on the rule of thumb for SEM as the sample. To collect data, the following measures were used: Brown's et al. (2005) Ethical Leadership scale, the Organizational Politics scale by Kacmar and Carlson (1997), the Knowledge Hiding scale by Serenko and Bontis (2016), the Individual Creativity scale by Zhou and George (2001), and the Hanke's (2006) Team Creativity scale. The validity of scales was confirmed using the content validity, and the reliability was examined using Cronbach's alpha, yielding values of 0.89 for the Ethical Leadership, 0.82 for the Organizational Politics, 0.92 for the Knowledge Hiding, 0.87 for the Individual Creativity, and 0.85 for the Team Creativity. For data analysis, SEM and the AMOS software were used. The results of the study fitted the research model, indicating that ethical leadership and organizational politics have a significant negative impact on knowledge hiding. Additionally, knowledge hiding has a significant negative effect on both individual and team creativity of employees. By reducing knowledge hiding behaviors through ethical leadership and organizational politics, the level of creativity among employees at both individual and team levels increases.

Objective: The purpose of this study was to provide a structural equation modeling for the effect of personality traits on bulimia nervosa with the mediating role of emotional intelligence in nurses. Methods: This research was a descriptive-correlational study that employed structural equation modeling with partial least squares. The research population consisted of all nurses of medical sciences hospitals in Tabriz in 2022. The research sample was 335 people who were selected using stratified sampling. The research tools employed for this purpose were the shorter form of NEO-FFI (NEO Five-Factor Inventory; 1985), the Binge Eating Scale (BES; Gormally et al., 1982), and Schering's Emotional Intelligence Questionnaire (1996). Partial least squares structural equation modeling (PLS-SEM) and Smart PLS 3 plus SPSS 26 were used for data analysis.  Results: The results showed that in the proposed model, the five main personality traits, except the extroversion variable, have a significant direct and indirect effect on bulimia nervosa,  and another implication of this research is the significant direct effect of emotional intelligence on bulimia nervosa. Another finding was the significant direct effect of the main personality traits on emotional intelligence. Conclusion: The results suggest that interventions for bulimia nervosa should embed education on personality traits and emotional intelligence because, according to the findings, the lower the personality traits, such as neuroticism and higher emotional intelligence, the lower the probability of bulimia nervosa.
