标题：Mindfulness‐based stress reduction (MBSR) for improving health, quality of life and social functioning in adults: a systematic review and meta‐analysis
摘要：Stress and stress‐related mental health problems are major causes of illness and disability. Mindfulness‐based stress reduction (‘MBSR’) is a group‐based health promotion intervention to improve health and the way people deal with stress and life?s challenges. The core ingredient is mindfulness training through physical and mental exercises practiced daily for eight weeks. The mindful non‐judgmental attitude of being present with what arises is practiced in the formal exercises and in everyday situations. This review assesses the effect of MBSR programs on outcome measures of mental and physical health, quality of life and social functioning in adults. MBSR has a moderately large effect on outcome measures of mental health, somatic health, and quality of life including social function at post‐intervention when compared to an inactive control. If 100 people go through the MBSR program, 21 more people will have a favourable mental health outcome compared to if they had been put on a wait‐list or gotten only the usual treatment. These results may be inflated by underreporting of negative trials and moderate heterogeneity (indicating differences between the trials). MBSR has a small but significant effect on improving mental health at post‐intervention compared to other active treatments. MBSR has the same effect as other active interventions on somatic health, and quality of life (including social function). There was no underreporting of negative trials, and heterogeneity (differences between trials) were small for mental health, moderate for quality of life and large for somatic health. The effects were similar across all target groups and were generally maintained at follow‐up (1?34 months). The effects were largely independent of gender and study sample. The effects seemed also largely independent of duration and compliance with the MBSR intervention. No studies report results regarding side‐effects or costs. Effects were strongly correlated to the effects on measures of mindfulness, indicating that the effects may be related to the increase in self‐reported mindfulness. Two thirds of the included studies showed a considerable risk of bias, which was higher among studies with inactive than active control groups. Studies of higher quality reported lower effects than studies with low quality. The overall quality of the evidence was moderate, indicating moderate confidence in the reported effect sizes. Further research may change the estimate of effect.
