Objectives: To determine the efficacy of Sahaja Yoga Meditation on a range of psychological effects. Methods: Databases were searched up to June Additionally an internet search was carried out. A total of 9 studies met the inclusion criteria. Methodological quality was assessed using the Cochrane Risk Assessment for Bias (RCTs), and the New Castle Ottawa Quality Assessment Scale (NRCTs). Results: Significant findings were shown in relation to the following psychological effects: anxiety, depression, stress, negative affect and neuroticism, happiness, experience of bliss, quality of life, positive affect, mood, change in personal values, emotional stability and less mental activity.

2. Non active control group + medication 15
8 week program: 3 times a week a 30 minute session
Depression: Hamilton Rating Scale for Depression (HAM-D).
Anxiety: Hamilton Rating Scale for Anxiety (HAM-A)
Depression – HAM-D (P<.001). Effect size : SYM vs. active control group on HAM-D: Cohen's d= 0.75 (95%CI 0.01 to 1.50), P=0.05
Anxiety - HAM-A (P<.001). Effect size: SYM vs. active control group on HAM -A: Cohen's d=1.16 (95%CI 0.35 to 1.88), P=0.004
Unclear to Low Risk of Bias
Conclusions
Evidence supports that SYM has beneficial effects on: >> Depression >> State Anxiety >> Stress >> Negative affect
Furthermore significant increases are reported in: >> Quality of Life >> Feelings of bliss >> Happiness >> Mood
Research also indicates: >> Lower levels of arousal >> Lower levels of mental activity
Quality of the RCTs: one study has a low risk of bias, one study a moderate risk of bias and two studies have an unclear risk of bias.
Quality of the NRCTs: moderate in one study and high in four studies.
Methods
Data sources and study selection
PubMed, MEDLINE (NLM), Cochrane Library and PsychInfo were searched up to June 2014.
Inclusion criteria : i) full text available; ii) publications of studies on the effect of Sahaja Yoga meditation; iii) randomized controlled trial studies, non-randomized controlled trial studies and controlled cohort studies; iv) main outcome measures that could be classified as psychological effects; v) participants were health adults or adults belonging to a clinical population.
Methodological quality assessment
Randomizes controlled trials were assessed using the Cochrane risk of bias assessment tool on 5 items for quality assessment.
Non-randomized controlled trials and the cohort study were rated using the Newcastle-Ottawa Quality Assessment Scale, an assessment tool on 9 items for quality assessment.

Recommendations
Future research would benefit from upholding to high methodological standards and report in a subsequent manner.
Shift in research focus on negative aspects (e.g. stress, anxiety, depression, negative affect) to positive effects (e.g. quality of life, happiness, resilience, positive affect)
