Thus, in 2001 the MRP designed and implemented the Meditation for Work Stress project, the largest RCT of meditation for occupational stress currently in the literature (178 participants). The study was specifically designed to determine whether or not this approach to meditation resulted in more than just a placebo effect.

Comparison groups Non-meditators Meditators Eight week stress management program Participants were asked to practice mental silence meditation twice daily for approximately 10-15 minutes each time with the aid of written and audio materials. At the end of the eight-week program, the meditator group showed significantly high improvements in terms of work- related stress, anxiety and depressive feelings Occupational Stress Inventory (OSI), State Trait Anxiety Inventory (STAI), General Health Questionnaire (GHQ28) and the Profile of Mood States (POMS).
