Abstract

Background: While various cognitive and behavioral approaches have shown varying degrees of efficacy in reducing the symptoms of obsessive-compulsive disorder (OCD), there is a lack of comparative studies on their effects. This randomized controlled study compared the effects of Cognitive-Behavior Therapy (CBT), Acceptance Commitment Therapy (ACT), Metacognitive Therapy (MCT), and Mindfulness-integrated CBT (MiCBT) on the symptoms of 100 adults with OCD.

Method: All participants were randomly allocated to four experimental groups (MiCBT, MCT, ACT, and CBT) and a control group and filled in the Yale-Brown Obsessive-Compulsive Scale at three time points (pre-treatment, post-treatment and follow-up).

Results: The results showed that all four interventions were efficacious in the short-term decrease of OCD symptoms, but only participants in the MiCBT and ACT groups maintained their therapeutic gains at follow-up. In addition, there was no significant difference in the long-term efficacy between the MCT and CBT approaches.

Discussion: According to these early results, MiCBT and ACT appear to be preferred approaches than MCT and CBT for reducing OCD symptoms. We discuss the possible active mechanisms causing these differences and the importance of replication studies.
