en Effectiveness of Mixed Reality-Based Exposure and Response Prevention Therapy in Reducing Clinical Symptoms in Individuals with Obsessive-Compulsive Disorder روان شناسی تربیتی Educational Psychology پژوهشي Original <div style="text-align: justify;">Objective: This study investigated the efficacy of mixed reality (MR)-assisted exposure and response prevention (ERP) therapy in alleviating obsessive-compulsive disorder (OCD) symptoms. Methods: Using a quasi-experimental design, 40 individuals with OCD were selected via convenience sampling and randomly assigned to either an intervention group (n=20) receiving 12 sessions of MR-based ERP therapy or a control group (n=20) with no intervention. Symptom severity was assessed using the Yale-Brown Obsessive-Compulsive Scale (Y-BOCS) at pre-test, post-test, and six-month follow-up. Results: Repeated measures ANOVA revealed a significant group × time interaction in obsession scores (p < 0.001, η² = 0.395). The intervention group exhibited a substantial reduction in symptoms from pre-test to post-test, with effects persisting at follow-up, while the control group showed no significant change. Conclusions: Findings suggest that MR-enhanced ERP therapy is an effective and durable intervention for reducing OCD symptoms, supporting its integration into future treatment protocols.</div> Obsessive-compulsive disorder, Exposure and response inhibition, Mixed reality 0 0 http://ieepj.hormozgan.ac.ir/browse.php?a_code=A-10-1012-1&slc_lang=en&sid=1 Sahand Shayesteh Mehr sahand.shayestehmehr@iau.ir 100319475328460011462 100319475328460011462 No Department of Psychology, Ard.c, Islamic Azad University, Ardabil, Iran Somayeh Taklavi staklavi@iau.ac.ir 100319475328460011463 100319475328460011463 Yes Department of Psychology, Ard.c, Islamic Azad University, Ardabil, Iran Ozra Ghaffari o.ghaffari@iauardabil.ac.ir 100319475328460011464 100319475328460011464 No Department of Psychology, Ard.c, Islamic Azad University, Ardabil, Iran
