Effectiveness of the Strength-Based Intervention on Subjective Well-being and Psychological Capital (PsyCap) in Female Students with Oppositional Defiant Disorder

Background: It is important to recognize and use the strengths of children with oppositional defiant disorder. The study was about whether strength-based intervention is effective on subjective well-being and psychological capital in children with oppositional defiant disorder.  Method: The research was a quasi-experimental pre-test-post-test design with a control group. The statistical population included 30 students with ODD in discreet six, which were selected through multi-stage cluster random in Tehran during the academic year 2022. Then, the individuals were randomly assigned to the experimental and control groups (each group n = 15). The Subjective Well-Being and Luthans' Psychological Capital (PCQ) questionnaires were administered. For the experimental group, a strength-based intervention was administered in eight sessions of 75 minutes per week, while the control group received no treatment. The data were analyzed using MANOVA in SPSS software version 26.  Results: Findings showed that the strength-based intervention had positive effects on subjective well-being (F1,28 = 23.42, P<0.001) and psychological capital (F1,28 = 28.12, P<0.001) in children with oppositional defiant disorder.  Conclusions: This type of approach builds on clients’ strengths, seeing them as resourceful and resilient when they are in adverse conditions. This study encourages new evidence for the efficacy of a strength-based intervention.
