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. Plain language summary Mindfulness training improves health and quality of life for adultsMindfulness‐based stress reduction (MBSR) is used to improve health, quality of life and social functioning. MBSR has a positive effect on mental health outcomes measured right after the intervention and at follow up. It also improves personal development, quality of life, and self‐reported mindfulness.

Longitudinal research investigating the enduring impact of mindfulness training is scarce. This study investigates the six-year effects of a seven-week mindfulness-based course, by studying intervention effects in the trajectory of dispositional mindfulness and coping skills, and the association between those change trajectories and subjective well-being at six-year follow-up. 288 Norwegian medical and psychology students participated in a randomized controlled trial. 144 received a 15-hour mindfulness course over seven weeks in the second or third semester with booster sessions twice yearly, while the rest continued their normal study curricula. Outcomes were subjective well-being, and dispositional mindfulness and coping assessed using the Five Facet Mindfulness Questionnaire and the Ways of Coping Checklist. Analyses were performed for the intention-to-treat sample, using latent growth curve models. At six-year follow-up, students receiving mindfulness training reported increased well-being. Furthermore, they reported greater increases in the trajectory of dispositional mindfulness and problem-focused coping along with greater decreases in the trajectory of avoidance-focused coping. Increases in problem-focused coping predicted increases in well-being. These effects were found despite relatively low levels of adherence to formal mindfulness practice. The findings demonstrate the viability of mindfulness training in the promotion of well-being and adaptive coping, which could contribute to the quality of care given, and to the resilience and persistence of health care professionals.Trial registration: Clinicaltrials.gov NCT00892138

Objectives. Mindfulness-based stress reduction (MBSR) enhances short-term psychological health in clinical and non-clinical samples, whereas studies examining long-term effects are scarce. This study examined whether the effects of a 7-week MBSR programme on mental health persisted at 2-and 4-year follow up and explored possible mechanisms of effect. Methods. In a two-site randomized controlled trial, 288 medical and psychology students were allocated to an MBSR intervention (n = 144) or a no-treatment control group (n = 144). During the 4-year follow-up period, the MBSR group was offered 90-min booster sessions semi-annually. The primary outcome measures were mental distress (General Health Questionnaire-GHQ) and well-being; these were measured at baseline (T0) and postintervention follow-up at 1 month (T1), 2 years (T1) and again at 4 years (T3). Secondary outcomes included coping, mindfulness, and meditation practice. Results. At 4-year follow up, the MBSR group showed significantly better scores on mental distress, mindfulness, avoidance coping, and problem-focused coping (Cohen's d = 0.23-0.42). Meditation practice positively predicted long-term mindfulness scores. Short-term effects in mindfulness-scores mediated long-term intervention effects in mental distress and coping. However, reversed mediation also was observed (i.e. changes in outcome mediating long-term mindfulness scores), and this indicates that initial changes in outcome and mindfulness are intrinsically intertwined and may both influence long-term effects. Small post-intervention effects on well-being and seeking social support did not persist at follow up. Conclusions. MBSR fostered enduring effects on mental distress and coping in medical and psychology students 4 years post-intervention.

Mindfulness has attracted increased interest in the field of health professionals’ education due to its proposed double benefit of providing self-help strategies to counter stress and burnout symptoms and cultivating attitudes central to the role of professional helpers. The current study explored the experiential aspects of learning mindfulness. Specifically, we explored how first-year medical and psychology students experienced and conceptualized mindfulness upon completion of a 7-week mindfulness-based stress reduction program. Twenty-two students participated in either two focus group interviews or ten in-depth interviews, and we performed an interpretive phenomenological analysis of the interview transcripts. All students reported increased attention and awareness of psychological and bodily phenomena. The majority also reported a shift in their attitudes towards their experiences in terms of decreased reactivity, increased curiosity, affect tolerance, patience and self-acceptance, and improved relational qualities. The experience of mindfulness was mediated by subjective intention and the interpretation of mindfulness training. The attentional elements of mindfulness were easier to grasp than the attitudinal ones, in particular with respect to the complex and inherently paradoxical elements of non-striving and radical acceptance. Some participants considered mindfulness as a means to more efficient instrumental task-oriented coping, whilst others reported increased sensitivity and tolerance towards their own state of mind. A broader range of program benefits appeared dependent upon embracing the paradoxes and integrating attitudinal elements in practising mindfulness. Ways in which culture and context may influence the experiences in learning mindfulness are discussed along with practical, conceptual, and research implications.Electronic supplementary materialThe online version of this article (doi:10.1007/s12671-016-0521-0) contains supplementary material, which is available to authorized users.
