The review
Who took part
The 163 studies were mostly of adults who meditated and were not in clinical groups. The 125 journal articles included 8,161 people in total.
What they did
Meditators practised a style such as transcendental meditation or mindfulness. Other groups got no treatment, and some did relaxation training. Studies lasted from days to months.
What happened
Meditation had a medium effect on attention, mindfulness and stress. Neutral personality traits hardly changed. Some results may have been missed from published studies.
