Examination of the Effectiveness of Mindfulness-Based Cognitive Therapy on Patients with Obsessive-Compulsive Disorder: Systematic Review and Meta-Analysis

Abstract

This study conducted a meta-analysis to examine the effectiveness of mindfulness-based cognitive therapy in patients with an obsessive-compulsive disorder. A meta-analysis is able to evaluate scientifically evidence at the highest level. Studies conducted between 2008 and 2020 were accessed from PubMed, Web of Science, Scopus, Science Direct, and other databases for evaluation and possible inclusion. Mindfulness-based cognitive therapy was shown to have a moderate effect (standardized mean difference: 0.283), but this this was enough to indicate a significant reduction in obsessive-compulsive symptoms in the experimental groups compared to the control groups (p = .002). Mindfulness-based cognitive therapy can be considered an effective approach for use with individuals with a diagnosis of obsessive-compulsive disorder.
