Winbush, N. Y., Gross, C. R., & Kreitzer, M. J. (2007). The effects of mindfulness-based stress reduction on sleep disturbance: a systematic review. Explore (New York, N.Y.), 3, 585–591.doi: 10.1016/j.explore.2007.08.003
To systemically evaluate the evidence regarding the effectiveness of mindfulness-based stress reduction (MBSR) for sleep disturbance.
Outcome measures included the Pittsburgh Sleep Quality Index (PSQI), sleep diaries, visual analog assessment of sleep quality, and self-reports. Four studies found significant differences in sleep quality from pre- to postintervention. Both studies with control or comparison groups showed no significant differences in sleep quality from pre- to postintervention. One study that included English- and Spanish-speaking participants demonstrated that English speakers showed more improved sleep quality than Spanish speakers. Two studies found significant differences in sleep quality related to home MBSR practice; however, one study found no significant differences related to practice time.
Given the very mixed results of the included studies, more research is needed to determine the impact of MBSR on sleep quality. Controlled studies that closely adhere to standardized MBSR interventions are necessary to fully describe the effects of MBSR on sleep quality. Comparisons between studies were limited due to the variability of sleep measures used. Studies using well-established and standardized measures of sleep quality are also needed.
Given the mixed results seen and because only one study on patients with cancer was included, this review did not provide strong evidence of the efficacy of MBSR.
