The Effectiveness of Mindfulness on Psychological Capital and Personality Organization in Young Adults with Substance Addiction in Esfarayen County

The present study aimed to investigate the effectiveness of solution-focused therapy on life expectancy and social self-esteem among spouses of individuals with substance dependence in Esfarayen County. This research employed a quasi-experimental design with a pretest-posttest format and a control group. The statistical population consisted of all spouses of individuals with substance dependence in Esfarayen who had referred to addiction treatment clinics in the year 2024 (1403 in the Persian calendar). Participants were selected through convenience sampling and volunteered to participate, provided they met the inclusion criteria.The final sample included 30 individuals, divided into an experimental group (n = 15) and a control group (n = 15). The experimental group received six 45-minute sessions of solution-focused brief therapy (SFBT) based on the approach of De Shazer and colleagues (2006). The research instruments included the Coopersmith Self-Esteem Inventory (1967) and the Snyder Hope Scale (1991).Data were analyzed using Multivariate Analysis of Covariance (MANCOVA) and Univariate ANCOVA via SPSS version 27 to assess the impact of the intervention. The statistical analysis revealed that solution-focused therapy had a significant positive effect on increasing life expectancy in the experimental group compared to the control group. Furthermore, the intervention significantly enhanced social self-esteem in the experimental group.Overall, the multivariate results indicated that solution-focused therapy simultaneously had a significant effect on increasing both life expectancy and social self-esteem. These findings support the effectiveness of short-term, solution-focused interventions in promoting psychological well-being and improving the quality of life among spouses of individuals with substance use disorders.
