The evaluation of religious and spirituality-based therapy compared to standard treatment in mental health care: A multi-level meta-analysis of randomized controlled trials.

Objective: Psychotherapies are increasingly incorporating spiritual and religious systems of belief and practice, which aligns with recent developments toward person-centered treatments. The main objective of this meta-analysis was to compare the efficacy of a religion and spiritually-based (R/S) therapy to non-R/S treatments.

Method: A multi-level meta-analysis was conducted to compare randomized controlled studies of the efficacy between R/S-based and regular treatments in mental health care setting.
