Aim: Obsessive-Compulsive Disorder (OCD) is a chronic mental health condition marked by persistent, intrusive thoughts and repetitive behaviors or mental acts that individuals feel compelled to perform. This study examines the efficacy of Cognitive Behavioral Therapy (CBT) in addressing irrational beliefs, anxiety sensitivity, and resilience in patients with OCD. Method: The research employed a semi-experimental, pre-test-post-test design with a control group. The statistical population included patients diagnosed with OCD at Ardabil City in 2024. A total of 34 students with patients were selected using purposive sampling and were divided into experimental (n=17) and control (n=17) groups. The experimental group attended eight 90-minute CBT sessions, while the control group received no intervention. Data collection involved administering the Obsessive-Compulsive Disorder Questionnaire, Irrational Beliefs Questionnaire, Anxiety Sensitivity Index, and Resilience Questionnaire. The data were analyzed using multivariate analysis of covariance in SPSS-27. Finding: The results indicated that CBT significantly decreases helplessness for change (F=38.59), demand for approval (F=27.35), problem avoidance (F=36.69), emotional irresponsibility (F=33.58), physical (F=34.28), cognitive (F=28.97), social (F=32.62), and increases resilience (F=38.29) in patients with OCD (P<0.001). Conclusion: These findings demonstrate that CBT effectively reduces irrational beliefs and anxiety sensitivity while enhancing resilience in OCD patients. This supports the broader use of CBT in clinical settings to address these psychological factors in OCD management specifically.
