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

Abstract

Meditation 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. Electronic 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. A 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. There 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.
