Aim: The present study was conducted with the aim of investigating the mediating role of addiction to social networks in the relationship between body image dissatisfaction and depression. Method: The current research was a correlational and structural equation type. The statistical population of the research included all male and female undergraduate, master's and doctoral students of Gilan University who were studying in 1400-1401. 304 people were selected by random sampling method and answered questionnaires of addiction to mobile based social networks (AMQBSN), dissatisfaction with body image (BICI) and depression (BDI-II). Data were analyzed using structural equation modeling with SPSS-27 and SMART-PLS-3 statistical software. Finding: The results of structural equations showed that body dissatisfaction has a direct and significant effect on depression. Also, addiction to social networks has a direct effect on depression. Addiction to social networks plays a mediating role in the relationship between body image dissatisfaction and depression. Result: As a result, the value of the goodness of fit (GOF) is equal to 0/24 which, by comparing it with acceptable values for GOF, shows the average fit of the model. According to the results of the present study, the expansion of the use of social networks, especially among students, has provided a platform for addiction, which increases dissatisfaction with body image, which leads to depression.

Objective: The present study aimed to investigate the structural model of loneliness and marital commitment with an attitude toward extra-marital relationships, with the mediation of identity styles in married women and men. Methods: For the research design, we used correlation and structural equation modeling. Statistical population including all married women and men of Ramsar City, among whom 230 individuals were selected through convenience sampling and responded to the Loneliness Scale Russell et al., (1980), Marital Commitment Questionnaire Adams & Jones (1997), Extra-marital Relationships Attitudes Questionnaire Wheatley's, (2008), and Identity Styles Scale Berzonsky (1989). All data were analyzed using SPSS 26, AMOS 24, and Macro Preacher & Hayes' (2008) program. Results: The findings indicated that loneliness and diffuse-avoidant identity styles have a significant and positive effect on the attitude toward extra-marital relationships, while marital commitment and commitment identity style have a significant and negative effect on the attitude toward extra-marital relationships. Bootstrapping results showed that information identity style, diffuse-avoidant identity styles, and commitment identity style play a mediating role in the relationships between loneliness and the attitude toward extra-marital relationships. Marital commitment indirectly affects the attitude toward extra-marital relationships through information identity style and commitment identity style. Conclusion: The research findings, by confirming the influential role of loneliness, marital commitment, and identity styles on extra-marital relationships, provide appropriate implications for work in the field of extra-marital relationships for practitioners in the family domain.

This study aimed to compare impulsivity, sleep disorder, and suicidal thoughts in marijuana users and non-users. The present study was a comparative causal study. The statistical population of this study included students consuming marijuana as well as non-consuming students at the University of Gilan. Fifty male students consuming marijuana in the age group of 18 to 33 years were selected by purposive and snowballs sampling, and 50 non-consuming students were selected and placed in the other group. Participants completed the Bart (1995) Impulse Scale, the Pittsburgh Sleep Quality Index (1989), and the Beck Suicide Thought Scale (1961), respectively. Data were analyzed using multivariate analysis of variance, chi-square test, and independent t-test with SPSS-22 software. The results showed that marijuana users scored higher on all three subscales of impulsivity, i.e., cognitive, motor, and unplanned impulsivity, and showed a significant difference with the non-consumer group. In terms of sleep disorders, marijuana abusers in six subscales out of seven subscales, i.e., mental quality, sleep delay, sufficient sleep, sleep disorders, hypnotic drug, and daily sleep disorders, a significant difference with the non-consumer group. Moreover, in the suicidal ideation scale, people with marijuana abuse had a higher mean score on the Beck suicidal thoughts scale. Conclusion: The research findings can be used in designing therapeutic interventions for people addicted to marijuana.
