Mindfulness-based stress reduction (MBSR) is a manualised group intervention using mindfulness training as a means of reducing the suffering associated with physical, psychosomatic and psychiatric illness. A review of the literature includes 31 randomised studies. Results indicate that MBSR may improve mental health and reduce symptoms of stress, anxiety and depression in both clinical and non-clinical populations. Implementation in the health-care system is recommended to take place over time to secure sufficient education of MBSR teachers in Denmark.
