Mindfulness-based stress reduction (MBSR) is an eight-week evidence-based program that offers secular, intensive mindfulness training to assist people with stress, anxiety, depression and pain. Developed at the University of Massachusetts Medical Center in the 1970s by Professor Jon Kabat-Zinn, MBSR uses a combination of mindfulness meditation, body awareness, yoga and exploration of patterns of behaviour, thinking, feeling and action. Mindfulness can be understood as the non-judgmental acceptance and investigation of present experience, including body sensations, internal mental states, thoughts, emotions, impulses and memories, in order to reduce suffering or distress and to increase well-being. Mindfulness meditation is a method by which attention skills are cultivated, emotional regulation is developed, and rumination and worry are significantly reduced. During the past decades, mindfulness meditation has been the subject of more controlled clinical research, which suggests its potential beneficial effects for mental health, as well as physical health. While MBSR has its roots in wisdom teachings of Zen Buddhism, Hatha Yoga, Vipassana and Advaita Vedanta, the program itself is secular. The MBSR program is described in detail in Kabat-Zinn's 1990 book Full Catastrophe Living.
In 1979, Jon Kabat-Zinn founded the Mindfulness Based Stress Reduction Clinic at the University of Massachusetts Medical Center, and nearly twenty years later the Center for Mindfulness in Medicine, Health Care and Society at the University of Massachusetts Medical School. Both these institutions supported the growth and implementation of MBSR into hospitals worldwide. Kabat-Zinn described the MBSR program in detail in his bestselling 1990 book Full Catastrophe Living, which was reissued in a revised edition in 2013. In 1993, the MBSR course taught by Jon Kabat-Zinn was featured in Bill Moyer's Healing from Within. In the year 2015, close to 80% of medical schools are reported to offer some element of mindfulness training, and research and education centers dedicated to mindfulness have proliferated.
