Keywords:Metacognitive therapy, Cognitive-behavior therapy, Intrusive thoughts obsessive-compulsive disorder
Background: According to WHO statistics, Obsessive-Compulsive Disorder (OCD) is the tenth most disabling condition. Thus, this study aimed to compare the efficacy of metacognitive therapy (MCT) against Cognitive-Behavior Therapy(CBT) on intrusive thoughts in obsessive-compulsive disorder.
Methods: In this study, a quasi-experimental design was used with pre-tests, post-test, and a control group. The study population was all patients who attended psychological clinics in Tehran, Iran, between August to September 2019. Using a purposeful sampling method, 24 OCD patients were selected from the study population, eight in every two experimental groups and eight in the control group. The experimental groups received 8, 120-minute sessions of therapy once a week. The study instruments were a questionnaire on demographic features and the Thought-Action fusion scale (TAFS). To analyze the data, inferential statistics (Multivariate Analysis of covariance (MANCOVA) by SPSS24.
Results: The results revealed that MCT and CBT treatments had a significant effect on variables (Pvalue<0.05). As observed, there is a significant difference in all subscales between the two groups of experiment and control in pre-test and post-test, after removing the pre-test effect (Pvalue<0.05). Moreover, findings showed that both approaches significantly differ from the control group when comparing variables between the two treatments. However, MCT treatment had the greatest effect.
Conclusions: Both MCT and CBT were found to be effective in reducing intrusive thoughts, though MCT had a greater reduction than CBT.
