Obsessive-compulsive disorder (OCD) is one of the most common anxiety disorders, often accompanied by maladaptive cognitive patterns such as perfectionism and the cognitive error of thought-action fusion. These dysfunctional beliefs can significantly impair the psychological and social functioning of women. The present study aimed to investigate the effect of cognitive-behavioral therapy (CBT) on reducing perfectionism and thought-action fusion in women with OCD. This research employed a quasi-experimental design with a pretest-posttest and control group. The statistical population consisted of women diagnosed with OCD who referred to the Sarohana Clinic in Tehran during winter 2024-2025, from whom 45 participants were selected through purposive sampling and assigned to three groups (CBT, short-term psychodynamic therapy, and control). Data were collected using the Revised Thought-Action Fusion Scale (TAF-R), the Ahvaz Perfectionism Questionnaire, and the Maudsley Obsessive-Compulsive Inventory (MOCI). The intervention included eight group CBT sessions, each lasting 40 minutes. Data were analyzed using ANCOVA. The results indicated that CBT significantly reduced perfectionism and thought-action fusion compared to the control group (p < 0.01). These findings highlight the effectiveness of CBT in modifying maladaptive cognitive errors and improving psychological well-being in women with OCD.
