Background: Major depressive disorder (MDD) is a common mood disorder. It has been shown that adolescents are more likely to experience depression during this term, with high recurrence rates and poor functional outcomes. The central purpose of this study was to investigate the effectiveness of family therapy on the psychological capital dimensions of adolescents with MDD.

Methods: The study was quasi-experimental, with a pre-test, post-test, and control group. The statistical population of this study was all adolescents with MDD who were referred to psychological clinics in Tehran, Iran, from October to December 2022. In this study, 30 eligible patients were selected and invited to take part purposefully. Researchers randomly divided the participants into two groups: a family therapy counseling group (n = 15) and a control group (n = 15). The interventions were held in eight 90-minute sessions, one session per week, and were designed and implemented to enable adolescents with MDD to promote their psychological capital dimensions based on the family therapy protocol. Beck Depression Inventory-II (BDI-II) and Psychological Capital Questionnaire (PCQ) were administered. Data were analyzed with SPSS software using multivariate analysis of covariance (MANCOVA).

Results: Family therapy intervention had a positive and significant effect on resilience (P < 0.001, F = 22.08), self-efficacy (P < 0.001, F = 18.54), hope (P < 0.001, F = 29.37), and optimism (P < 0.001, F = 21.50) in adolescents with major depression.

Conclusion: Family therapy increased resilience, self-efficacy, hope, and optimism in patients with MDD. Therefore, family therapy for adolescents with MDD is recommended to increase the psychological capital dimensions and improve their quality of life (QOL).
