Purpose: The purpose of this study was to model social trust based on social intelligence, social identity, and social isolation based on the moderating role of gender and family economic status on secondary school students in Tehran. Methodology: The research method was descriptive correlation based on modeling and structural equations. The statistical population consisted of all high school students in Tehran in the year 2019, from which 495 students were selected by multistage cluster sampling method. Data collection was done based on Social Trust Questionnaire (Dr Safari nia, Sharif 1389, base on Johnson's theory, 1993), Social Intelligence Questionnaire (Ang Ton Teeth, 2008), Social Identity Questionnaire (Dr Safari nia, Roshan 1390, base on Jenkins's theory, 2000) and Social Isolation Questionnaire (Modaresi Yazdi, 2014). Data analysis was done by SPSS19 and PLS-SEM software in two descriptive and inferential sections. Structural equation modeling was used to test the hypotheses. Findings: The results showed that based on the identified dimensions and components, the research model had a good fit. The results also showed that the results of social isolation, social intelligence and social identity had an impact on students' social trust. It should be noted that the social isolation variable has a negative coefficient and social intelligence and social identity have a positive path coefficient. It is therefore concluded that gender has a moderating effect on the coefficients of variable social identity on social trust. The coefficient indicates that social identity in girls has a greater impact on social trust than boys. It should be noted that gender has no moderating role in the relationship between social intelligence and social isolation with social trust. The results also showed that the relationship between social identity, social intelligence and social isolation with social trust in the high and low economic status group was different. Conclusion: Therefore, it is concluded that the economic situation has a moderating effect on the coefficients of the variables of social identity, social intelligence and social isolation on social trust.

urpose: The aim of this study was to model the positive development of adolescence based on self-regulation, social competence and parental bond with the mediating role of perception of school atmosphere. Methodology: The research method was correlation based on structural equations. The statistical population included all female high school students in Tehran who were studying in 2019-20. Using cluster random sampling method, 400 students were selected as the research sample. To collect data from the Geldhof Adolescent Positive Development Questionnaire (2014), the Self-Regulatory Questionnaire Moilanen (2007), the Felner Social Competence Questionnaire (1990), the Parker Parental Bonding Questionnaire (1979), and the Trickett & Moos Atmosphere Perception Questionnaire (1973) was used. Data analysis was performed using structural equation method using lisrel and SPSS software. Findings: The results showed that the research has a good fit and the positive development of adolescence can be predicted based on the variables of self-regulation, social competence and parental bond with the mediating role of perception of school atmosphere and the research hypotheses were confirmed. Overall, the results show that to predict the positive development of adolescence, we can emphasize self-regulation, social competence and parental bond with the mediating role of perception of school atmosphere and the obtained model can be used in teaching positive adolescent development. Conclusion: The development of self-regulatory variables, social competence and parental bonding is the best way to prevent problems related to the development of adolescent behavior and promoting these components and their education and improvement can be very effective in forming a positive adolescent development.
