Mindfulness for obsessive-compulsive disorder: a systematic review and meta-analysis

Area of Science:

• Psychiatry
• Clinical Psychology
• Behavioral Science

Background:

• Obsessive-compulsive disorder (OCD) is a debilitating mental health condition.
• Mindfulness-based interventions (MBIs) have been explored as a potential treatment for OCD.
• The current evidence on the efficacy of MBIs for OCD is limited and requires further investigation.

Purpose of the Study:

• To systematically review and meta-analyze the effectiveness of mindfulness-based interventions (MBIs) in treating adults with obsessive-compulsive disorder (OCD).
• To compare MBIs against active control interventions, including established OCD treatments.

Main Methods:

• Systematic review and meta-analysis of randomized controlled trials (RCTs).
• Inclusion of six RCTs with 499 adult participants.
• Primary outcomes assessed included obsessive-compulsive symptoms, dropout rates, anxiety, depressive symptoms, mindfulness skills, and quality of life.

Main Results:

• Mindfulness-based interventions (MBIs) did not demonstrate significant superiority over other active treatments in reducing obsessive-compulsive symptoms.
• No significant differences were found in dropout rates, anxiety, or depressive symptoms between MBIs and control groups.
• A minor, non-clinically relevant improvement in mindfulness skills was observed, while quality of life outcomes were inconsistent.

Conclusions:

• Mindfulness-based interventions (MBIs) are not significantly more effective than established treatments like exposure with response prevention (ERP), psychoeducation, and cognitive restructuring for OCD.
• Current evidence suggests MBIs do not offer a distinct advantage for core OCD symptom reduction.
• Further research may be needed to explore specific patient subgroups or adjunctive roles for MBIs in OCD treatment.
