Randomized controlled trials on Mindfulness-Based Stress Reduction (MBSR) have shown mitigation of stress, anxiety, and dysphoria in a general population sample and reduction in total mood disturbances and stress symptoms in a medical population sample. Furthermore, RCTs in Mindfulness-Based Cognitive Therapy (MBCT) have demonstrated a 50 % reduction of depression relapse for individuals, who have experienced three or more previous episodes.
