Mindfulness-based programs (MBPs) show a small but significant benefit for cognitive performance, particularly for executive function and working memory, according to a meta-analysis of 56 randomized controlled trials involving 2,931 adults. The overall effect favoring MBPs over comparators was small (g = 0.15). Benefits were strongest for non-clinical samples and adults over 60, and when MBPs were compared to inactive controls rather than active ones. No significant effects were found for other cognitive domains. Most studies had unclear risk of bias, and some statistical results were unreliable. The findings partially support the idea that mindfulness practice can enhance certain cognitive abilities.
Mindfulness-based programs improve well-being in college students, with the strongest evidence for reducing anxiety and depressive symptoms. A systematic review and meta-analysis of 58 randomized controlled trials found that mindfulness interventions significantly outperformed both active and inactive controls, with the most marked effects on anxiety, depression, and mindfulness. Greater success appeared for clinical populations. Online programs performed equivalently to in-person programs, and non-mindfulness-based programs were equivalent to mindfulness-based programs after controlling for other factors. Publication bias and other quality issues emerged. More studies using stronger methods are needed to evaluate effects on additional health outcomes and online interventions in clinical populations.
