The systematic review focused on stand-alone, standardized MBSR programs for adults with chronic pain. Researchers searched PubMed, Web of Science, Embase, Cochrane, Scopus, EBSCO and APA PsycNet from their inception through September 2025, and used an outcome-specific framework to compare the intervention’s effects on pain, depression and anxiety. Eligible studies were randomized controlled trials, allowing the analysis to draw on evidence in which participants were assigned to MBSR or a comparison condition. The protocol was prospectively registered in PROSPERO, and effect sizes were pooled with random-effects models.

Across 20 studies reporting pain-related outcomes, the pooled estimate favored MBSR but crossed the threshold for statistical significance, with a Hedges’ g of −0.40 and a 95% confidence interval from −0.85 to 0.05; p = 0.081. Because this interval includes no effect, the review found insufficient evidence to establish that MBSR reduces pain. Depressive symptoms showed a larger and statistically significant pooled effect across 25 trials, with Hedges’ g of −1.09 and a 95% confidence interval of −1.54 to −0.64. Anxiety symptoms also improved significantly across 18 trials, with Hedges’ g of −0.73 and a 95% confidence interval of −1.21 to −0.25. These estimates indicate that the average intervention effects favored MBSR, although the negative Hedges’ g values represent standardized differences in the direction of lower symptom scores rather than direct measures of pain relief or clinical remission.

Substantial heterogeneity was observed for all three outcomes, meaning that the average effects were not consistent across the included studies. The researchers also assessed heterogeneity, moderators, robustness, small-study effects, risk of bias and certainty of evidence. The combination of substantial heterogeneity, wide prediction intervals and very-low-certainty evidence means that the pooled depression and anxiety results should not be interpreted as uniform benefits for every person with chronic pain. Differences in participants, program delivery and study conditions may affect outcomes, and the available trials cannot yet reliably identify the patient groups or implementation settings most likely to respond. The authors concluded that more standardized trials are needed to clarify the role of MBSR within multidimensional chronic-pain management. The review therefore supports a cautious interpretation: MBSR may help psychological symptoms accompanying chronic pain, while its effect on pain itself remains uncertain.
