Mindfulness-based Stress Reduction (MBSR) reduces short-term psychological distress in non-physician health workers with patient contact, but effects are not maintained at four-month follow-up. In a three-arm randomized controlled trial, 105 participants were assigned to MBSR, a Stress Management Course (SMC), or a wait-list. MBSR reduced psychological distress on the GHQ-12 and OQ-45 compared to both SMC and wait-list post-intervention. Only MBSR was associated with a 23% decrease in the cortisol awakening response. At four-month follow-up, only the 'social role' subscale of psychological distress remained significantly improved versus SMC.
