A randomized controlled trial was conducted with 30 participants from Indonesia who had experienced psychological trauma. Participants were randomly assigned to either an intervention group (n = 15), which received eight weekly sessions of trauma-informed art therapy, or a control group (n = 15), which received no intervention. Each session lasted 75 to 90 minutes and was designed to promote emotional safety, self-expression, and identity integration through structured art-making activities. Assessments were conducted at three time points: pre-intervention, post-intervention, and five-month follow-up. Dissociation was measured using the Dissociative Experiences Scale (DES), and self-esteem was assessed using the Rosenberg Self-Esteem Scale (RSES). Data were analyzed using repeated measures ANOVA and Bonferroni post-hoc tests in SPSS-27. Results indicated significant time-by-group interaction effects for both dissociation (F(2,56) = 28.47, p &lt; .001, η² = .52) and self-esteem (F(2,56) = 36.09, p &lt; .001, η² = .55). Participants in the intervention group demonstrated a substantial reduction in dissociative symptoms from pre-test (M = 52.67, SD = 6.45) to post-test (M = 38.41, SD = 5.88) and follow-up (M = 36.79, SD = 6.12). Similarly, self-esteem significantly increased from pre-test (M = 19.26, SD = 3.78) to post-test (M = 28.47, SD = 4.10) and follow-up (M = 29.13, SD = 3.95). No significant changes were observed in the control group across time points. Trauma-informed art therapy is an effective intervention for reducing dissociative symptoms and improving self-esteem among individuals with trauma histories. The intervention’s effects were maintained at five-month follow-up, indicating its potential as a sustainable therapeutic approach.</p> https://www.journals.kmanpub.com/index.php/psychnexus/article/download/3920/6706
