Search strategy combined terms related to meditation (eg Meditation, mindfulness, trancedental meditation) with terms associated with mental health outcomes such as depression, anxiety, stress, PTSD and other mental health conditions. Inclusion criteria were met by studies with Randomized controlled trials (RCTS) or meta-analysis published published between 2014 and 2024, assessing the effect of meditation on mental health outcomes. Exclusion criteria met by non-randomized studies, case reports, qualitative studies and studies focusing solely on physiological outcomes. The 42 included studies comprised a total of 3,876 participants. Sample size ranged from 24 to 286 participants (m=92.3, SD=62.7). Findings from systematic review synthesized from 42 randomized controlled trials indicated that meditation-based interventions have moderate to large effects on depression, anxiety and stress, with similar but significant effects on PTSD symptoms, depression and anxiety. It was concluded that the systematic review provides robust evidence supporting the effectiveness of meditation therapy in improving various mental health outcomes.
