Mantra meditation for mental health in the general population: A systematic review

Abstract

IntroductionMeditation has attracted increased attention in the literature as a non-pharmacological strategy to foster positive mental health amongst the general population. This systematic review aims to summarise studies of mantra meditation (which includes Transcendental Meditation, TM®) to understand its potential value in fostering positive mental health and alleviating negative affectivity in non-clinical populations. MethodsElectronic databases were searched for English language, peer-reviewed empirical studies (published between 1970 and 2018) that related to mantra meditation, reported at least one outcome of mental health and utilised healthy, non-clinical populations. Studies were assessed for quality and risk of bias using the Quality Appraisal Tool for Quantitative Studies (QATQS). Data abstraction was facilitated by a tailored data extraction form. ResultsA total of 2171 records were identified, of which 37 were included in this review. Studies report on outcomes of anxiety, stress, depression, burnout, anger and psychological distress. 78% of studies utilised the TM programme. Findings indicate that mantra meditation interventions may have minimal to moderate beneficial effects on mental health in general populations. Over 90% of studies were considered to be of weak quality. ConclusionsThere is some evidence that mantra meditation can improve mental health and negative affectivity in non-clinical populations, however poor study quality may hinder the extent to which one can be certain about the accuracy of these findings. Mantra meditation may be considered a useful adjunct to workplace wellbeing initiatives or educational programmes. Further studies of higher quality that incorporate cost-effectiveness analyses are warranted.
