In the qualitative phase, a descriptive phenomenological approach was used, and data were collected through semi-structured interviews with 10 addiction specialists and therapists in Tehran, which were analyzed using Colaizzi’s thematic analysis method. The extracted themes informed the development of a 12-session family-centered psychological intervention program whose content validity was confirmed using CVR and CVI indices. In the quantitative phase, a quasi-experimental pretest–posttest design with a control group was implemented. Thirty women with substance use disorders were selected from addiction treatment centers in Tehran and randomly assigned to an experimental group (n = 15) and a control group (n = 15). The Self-Worth Scale was administered before and after the intervention. Data were analyzed using multivariate and univariate analyses of covariance in SPSS.</p> <p>Findings: Multivariate analysis of covariance revealed a significant overall effect of the intervention on posttest self-worth and its components (p &lt; .001). Univariate ANCOVA indicated significant improvements in total self-worth, family support, competition and achievement, physical appearance, divine love, academic competence, virtue and moral integrity, and approval from others in the experimental group compared with the control group (all p &lt; .01), with large effect sizes.</p> <p>Conclusion: The family-centered psychological intervention was highly effective in enhancing self-worth and multiple dimensions of psychological functioning in women with substance use disorders, highlighting the central role of family processes in addiction recovery and psychosocial rehabilitation.</p> https://journals.kmanpub.com/index.php/aftj/article/download/4928/8900
