A meta-analysis of 47 randomized clinical trials with 3,515 participants found that mindfulness meditation programs produce small to moderate reductions in anxiety, depression, and pain compared to placebo controls. At 8 weeks, effect sizes were 0.38 for anxiety, 0.30 for depression, and 0.33 for pain; benefits for anxiety and depression persisted at 3–6 months. Evidence for improved stress, distress, and mental health-related quality of life was low, and there was insufficient or no evidence that meditation improves positive mood, attention, substance use, eating habits, sleep, or weight. Meditation programs were not superior to active treatments such as drugs, exercise, or other behavioral therapies.
