Mindfulness on Rumination in Patients with Depressive Disorder: A Systematic Review and Meta-Analysis of Randomized...

Area of Science:

• Psychiatry and Behavioral Sciences
• Clinical Psychology
• Evidence-Based Medicine

Background:

• Depression is frequently associated with rumination, a repetitive negative thought process.
• Mindfulness-based interventions (MBIs) show promise in managing depressive symptoms and associated cognitive patterns.

Approach:

• A systematic review and meta-analysis of randomized controlled trials (RCTs) were conducted.
• Data from 19 RCTs involving 1138 patients were analyzed.
• The Rumination Scale, depression, mindfulness, and anxiety indexes were primary and secondary outcome measures.

Key Points:

• MBIs significantly reduced rumination (SMD = -0.46) and depression (SMD = -0.58) in patients.
• MBIs also improved mindfulness (SMD = 0.95) and reduced anxiety (SMD = -0.45).
• Interventions in Asia showed superior rumination reduction compared to Europe/North America (SMD = -2.05).
• Recent MBIs (past 5 years) demonstrated significantly greater improvements in mindfulness (SMD = 2.74).

Conclusions:

• MBIs are effective treatments for depression, improving rumination, depression, anxiety, and mindfulness.
• Regional differences and publication year impact MBI effectiveness, suggesting tailored intervention design.
• Further high-quality RCTs are needed to confirm these findings and explore variations.
