Effect of mindfulness on anxiety and depression in insomnia patients: A systematic review and meta-analysis
Frontiers in Psychiatry March 2, 2023 Hangyu Li, Wanli Qin, Nannan Li et al.
A meta-analysis of 10 randomized controlled trials involving 1,058 people with insomnia and anxiety-depressive symptoms found that adding 4–12 weeks of mindfulness therapy to conventional treatment significantly reduced depression and anxiety scores compared with conventional treatment alone. Mindfulness therapy lowered Hamilton Depression Scale scores by an average of 3.67 points and Hamilton Anxiety Scale scores by 3.23 points. It also reduced Self-Rating Depression Scale scores by 6.49 points and Self-Rating Anxiety Scale scores by 7.97 points. The authors conclude that mindfulness therapy can improve anxiety and depression symptoms in people with insomnia, though they note methodological limitations and call for further well-designed trials.
