Abstract
Background: Meditation is defined as a form of cognitive training that aims to improve attentional and emotional self-regulation. This systematic review aims to evaluate the available scientific evidence on the effectiveness and safety of mantra-based meditation techniques (MBM), in comparison to passive or active controls, or other active treatment, for the management of mental health symptoms. Methods: MEDLINE, EMBASE, Cochrane Library, and PsycINFO databases were consulted up to April 2021. Randomised controlled trials regarding meditation techniques mainly based on the repetition of mantras, such as transcendental meditation or others, were included. Results: MBM, compared to control conditions, was found to produce significant small-to-moderate effect sizes in the reduction of anxiety (g = −0.46, IC95%: −0.60, −0.32; I2 = 33%), depression (g = −0.33, 95% CI: −0.48, −0.19; I2 = 12%), stress (g = −0.45, 95% CI: −0.65, −0.24; I2 = 46%), post-traumatic stress (g = −0.59, 95% CI: −0.79, −0.38; I2 = 0%), and mental health-related quality of life (g = 0.32, 95% CI: 0.15, 0.49; I2 = 0%). Conclusions: MBM appears to produce small-to-moderate significant reductions in mental health; however, this evidence is weakened by the risk of study bias and the paucity of studies with psychiatric samples and long-term follow-up.

Despite showing a very intense effect (g = −8.75, 95% CI: −10.81, −6.70), the study by Rees et al (2013) [66] was not included in the MA because it showed a high risk of selection bias (59% of the participants assigned to the meditation group did not start the program, and a paired sample design was subsequently carried out)
Apart from the studies focused on PTSD, ness of on mental health outcomes
Summary
Meditation can be defined as a cognitive training aimed to improve attentional and emotional selfregulation [2]. This is a general term that includes a wide and heterogeneous set of attention and concentration practices, mostly derived from ancient traditions [3]. Meditation is defined as a form of cognitive training that aims to improve attentional and emotional self-regulation. This systematic review aims to evaluate the available scientific evidence on the effectiveness and safety of mantra-based meditation techniques (MBM), in comparison to passive or active controls, or other active treatment, for the management of mental health symptoms.
