Effects of mindfulness-based stress reduction on adults with sleep disturbance: an updated systematic review and meta-analysis.
Study Goal
The researchers aimed to determine the clinical effects of Mindfulness-Based Stress Reduction (MBSR) on sleep quality and sleep-related daytime impairment in adults with sleep disturbances, including chronic insomnia disorders.
Results Summary
MBSR did not improve objective or subjective sleep quality in chronic insomnia and cancers, though it might have been marginally effective in improving subjective sleep quality compared to waitlist controls, albeit with substantial heterogeneity. The study noted that many included RCTs had small sample sizes and were prone to biases.

OBJECTIVE: Mindfulness-based stress reduction (MBSR) is a meditation-based therapy originally recommended for stress management. However, it is currently used to alleviate sleep disturbances. Therefore, this contemporary systematic review aimed to elucidate the clinical effects of MBSR on sleep quality and sleep-related daytime impairment in adults with sleep disturbances, including chronic insomnia disorders. DESIGN: Systematic review and meta-analysis of randomised controlled trials (RCTs). METHODS: A comprehensive search was conducted using the following databases: Ovid MEDLINE, AMED, Ovidembase, PsycINFO, Cochrane Library, CINAHL, and four domestic databases: KoreaMed, KISS, KMbase and NDSL. The final search update was performed in June 2022. Two researchers independently selected relevant studies, assessed the risk of bias and extracted the data. RESULTS: Of the 7516 records searched, 20 RCTs and 21 reports were included. In the subgroup analysis, MBSR did not improve objective or subjective sleep quality in chronic insomnia and cancers. However, MBSR versus waitlist control might have been effective in improving subjective sleep quality, but with substantial heterogeneity (standardised mean difference=-0.32; 95% CI: -0.56 to -0.08; I CONCLUSIONS: MBSR might be ineffective for improving sleep quality in patients with chronic insomnia and cancers. In addition, more than half of the RCTs included in this review had small sample sizes and were vulnerable to performance and detection biases. Therefore, well-designed RCTs with larger sample sizes are required to confirm the clinical effects of MBSR in adults with sleep disturbances. PROSPERO REGISTRATION NUMBER: CRD42015027963.
