One of the necessities of life in the modern era is to pay attention to the quality of life. The quality of life is defined and identified in four dimensions: mental health, physical health, environmental health and the quality of social relationships. This research study was descriptive-causal employing the survey method and the statistical population of the study was high school male students in Babol with a sample size of 350 people. Inspired by Lutz's psychological theory, psychological capital variable with four dimensions of hope, resilience, optimism and self-efficacy and social capital variable also inspired by the theories of Putnam, Coleman and Bourdieu with three dimensions of social relations, trust, and Participation were measured. The findings of the study showed that the quality of life were estimated to be low in about 12 percent of respondents, middle in 26 percent of them, and high in 62 percent of them. The findings of the study in evaluating the hypotheses indicate that psychological capital and all four dimensions have an impact on the quality of life, and this effect is positive and statistically significant. The results of regression analysis and path analysis showed that social capital had the highest share and influence among all predictors of quality of life and this effect was controlled by all other variables. That is, for one unit (standard deviation) of change in the social capital variable, one would expect that the quality of life among students would increase by 30 units. , For one unit of change in student family income, the quality of life changed 14 units, and for one unit of change in psychological capital, one can expect 11 units of change in the quality of life of students.

In this article, the role of cultural capital in strengthening social trust in Iran has been studied. Social trust is one of the most important components of social development. It is one of the important aspects of social relations. Cultural capital, which is an indicator of cultural development, is used objectively and the scientific and cultural qualities of a person can affect social trust. The research approach in this study is descriptive-causal and has been conducted in a cross-sectional and temporal manner. The statistical population includes women and men over 18 years of age in Zanjan. Findings showed that there is a relatively high correlation between cultural capital and social trust and this correlation is statistically significant. Household income showed a negative relationship with social trust, so that by increasing the income level of families, their level of social trust was reduced. But there was a positive and direct correlation between the education of citizens and their parents' education and social trust, as the level of education and also literacy of individuals increased social trust. Similarly, the results of regression analysis showed that the variables of cultural capital, income and education of the individual and responsible parents were 64 percent of the total dependent variable variation, but the share of the main variable of the research, namely, cultural capital, in this explanation was 33 percent.
