Objectives Meditation interventions typically show small to moderate effects on health and well‐being, but we know little about how these effects vary across individuals. This meta‐analytic study investigates the relationship between baseline participant characteristics and the outcomes of meditation. Methods A systematic search yielded 51 eligible studies with 7782 participants. A combination of subgroup analyses and meta‐regression based on the random‐effects model were used. Results We found that a higher baseline level of psychopathology or depression was associated with deterioration in mental health after a meditation intervention. On the other hand, participants with higher scores on interpersonal variables, motivation, medical conditions, and mindfulness showed higher levels of positive meditation outcomes. Higher well‐being and stress were simultaneously associated with moderate increases in negative and positive meditation outcomes. Participant demographics, psychological traits, self‐concept, and length of meditation practice did not significantly influence the response to meditation. Conclusions Overall, we found that meditation interventions affect participants differently, and identified some of the individual characteristics that should be considered when using meditation interventions.
