The experimental group participated in eight weekly 90-minute sessions focused on humor-based techniques designed to enhance emotional regulation, self-esteem, and social interactions. Dependent variables were measured using standardized tools: depression was assessed via the Beck Depression Inventory-II, and self-esteem was assessed with the Rosenberg Self-Esteem Scale at three time points—pre-test, post-test, and a five-month follow-up. Data were analyzed using repeated-measures ANOVA and Bonferroni post-hoc tests through SPSS-27.</p> <p><strong>Findings: </strong>The findings revealed significant reductions in depression (F(2,54) = 28.94, p &lt; .001, η² = .539) and significant increases in self-esteem (F(2,54) = 26.75, p &lt; .001, η² = .498) for the experimental group compared to the control group, with substantial improvements maintained at five-month follow-up. Specifically, depression scores in the experimental group significantly decreased from pre-test (M = 27.60, SD = 4.12) to post-test (M = 15.87, SD = 3.45, p &lt; .001) and remained stable at follow-up (M = 16.53, SD = 3.72). Self-esteem scores significantly improved from pre-test (M = 18.80, SD = 3.67) to post-test (M = 28.40, SD = 4.18, p &lt; .001) and remained high at follow-up (M = 27.87, SD = 4.01).</p> <p><strong>Conclusion: </strong>Humor-based group therapy effectively reduced depressive symptoms and significantly enhanced self-esteem among adolescents, with beneficial effects persisting at five months post-intervention, suggesting it as a promising therapeutic option for adolescent mental health interventions.</p> </td> </tr> </tbody> </table> https://journals.kmanpub.com/index.php/jayps/article/download/3888/6632
