This aim of this study was developing a model for predicting decision-making ability based on the parent-child relationship with the mediation of autonomy and self-concept in adolescents. This research was applied in terms of purpose and descriptive - correlational based on the nature of research and data collection. The statistical population consisted of students of the high school in Tehran and the statistical sample was equal to ۳۹۰ people, which was obtained based on Mueller's rule based on the ratio of ۱ to ۵ items to the number of samples. The research tools include the Melbourne decision-making ability questionnaire (۱۹۹۷), Fine et al (۱۹۸۳) quality of parent-child relationships, Deci and Ryan (۲۰۰۰) autonomy in the basic psychological needs scale of and Beck, Ester, Brown Epstein (۱۹۹۲) self-concept. Statistical analysis was done using descriptive analysis in    and inferential analysis in LISREL software.   The findings of the research showed that the parent-child relationship (with a value of t equal to ۷.۸۳) directly has a significant effect on decision-making ability; In addition, autonomy and self-concept have a mediating role in the relationship between parent-child relationship and decision-making ability, and based on this, the direct and indirect relationship between parent-child relationship and decision-making ability was accepted. As a result, decision-making ability is a structure that is influenced by both individual variables and family relationships. Based on this, psychologists and school counselors are suggested to pay attention to the effective role of the family in order to improve the decision-making ability of adolescents while empowering them individually.
