The effectiveness of cognitive-behavioral therapy on thought fusion and severity of obsessive-compulsive symptoms in patients with obsessive-compulsive disorder

Authors
Abstract
This study aimed to determine the effectiveness of cognitive-behavioral therapy on thought fusion and the severity of obsessive-compulsive symptoms in patients with obsessive-compulsive disorder in Tehran. The present study method was a quasi-experimental design with a pre-test-post-test design with a control group. The statistical population included all women with obsessive-compulsive disorder who visited clinics in Tehran between April and June 1404, from which a sample was selected using convenience sampling and randomly assigned to two experimental and control groups. The measurement tools included the Thought Fusion Questionnaire and the Yale-Brown Obsessive-Compulsive Scale. The experimental group underwent cognitive-behavioral therapy sessions, while the control group did not receive any intervention. The data were analyzed using analysis of covariance. The results showed that after the intervention, there was a significant difference between the experimental and control groups in the variables of thought fusion and the severity of obsessive symptoms. Cognitive-behavioral therapy significantly reduced the rate of thought fusion and the severity of obsessive-compulsive symptoms in patients in the experimental group compared to the control group. Based on the research findings, cognitive-behavioral therapy, by correcting cognitive distortions and reducing thought-action fusion, is an effective approach in improving the clinical symptoms of patients with obsessive-compulsive disorder, and the use of this treatment protocol is recommended in rehabilitation centers and psychological clinics.
