A randomized controlled trial was conducted with 30 participants from Tehran, diagnosed with SAD. Participants were randomly assigned to an intervention group (n = 15) or a control group (n = 15). The intervention group underwent an eight-session psychosocial rehabilitation program. Data were collected at baseline, post-intervention, and five-month follow-up using the Self-Determination Scale (SDS) and the Collective Efficacy Scale (CES). Statistical analyses included repeated measures ANOVA and Bonferroni post-hoc tests, conducted using SPSS-27. The intervention group showed significant improvements in self-determination from baseline (M = 24.67, SD = 5.43) to post-intervention (M = 32.12, SD = 4.89) and follow-up (M = 31.78, SD = 5.12) compared to the control group, which showed no significant changes (baseline: M = 23.89, SD = 5.67; post-intervention: M = 24.34, SD = 5.56; follow-up: M = 24.12, SD = 5.23). Similarly, collective efficacy significantly improved in the intervention group from baseline (M = 38.45, SD = 6.78) to post-intervention (M = 45.32, SD = 5.67) and follow-up (M = 44.89, SD = 5.43), while the control group showed no significant changes (baseline: M = 37.89, SD = 6.34; post-intervention: M = 38.12, SD = 6.56; follow-up: M = 38.00, SD = 6.12). ANOVA results indicated significant main effects of group and time, and significant time × group interactions for both self-determination and collective efficacy (p &lt; .001). The psychosocial rehabilitation program effectively enhanced self-determination and collective efficacy among individuals with SAD, with these improvements sustained over a five-month follow-up period. These findings support the incorporation of psychosocial rehabilitation into therapeutic practices for SAD to improve long-term outcomes.</span></p> https://www.journals.kmanpub.com/index.php/jditf/article/download/6290/11758
