Purpose: This study investigates the effect of marbling art on improving the psychological resilience of mothers of children with intellectual disabilities. Design and methods: This study employed a pretest-posttest control group design with 40 mothers of children with mild to moderate intellectual disabilities attending a special education school in T & uuml;rkiye's Western Black Sea region. Participants were randomly assigned to either an intervention or control group. The intervention group attended eight 60-min marbling art sessions over four weeks, while the control group received no intervention. Data were collected at three points-before, after, and one month following the intervention-using a Demographic Information Form and the Psychological Resilience Scale for Adults. Results: The results showed a statistically significant increase in psychological resilience scores in the intervention group compared to the control group at both post-test (p = 0.003) and follow-up (p = 0.007). Conclusion: These findings indicate that marbling art is an effective intervention for enhancing psychological resilience among mothers of children with intellectual disabilities. By promoting self-expression and emotional regulation, marbling art may improve the overall well-being of caregivers. Pratical implications: Marbling art offers a creative, low-cost, and culturally meaningful method to enhance psychological resilience in mothers of children with intellectual disabilities. Health professionals and educators can incorporate this intervention into psychosocial support programs to promote emotional expression and stress management. Its accessibility makes it a promising tool for widespread use in community and family-based mental health services. (c) 2025 Elsevier Inc.
