Integrative systematic review of psychodrama psychotherapy research: Trends and methodological implications.

The database search and a hand search resulted in 31 psychodrama intervention publications. Overall, these studies examined the effects of psychodrama on more than 20 different outcomes and most studies had adult clients. The next largest group was adolescents, whereas only two studies involved children. Thus psychodrama intervention research in the last decade suggests there are promising results in all methodologies, and highlights the need to enhance methodological as well as reporting quality and to theorize and examine modality-specific mechanisms that lead to therapeutic change. Recommendations to improve methodology, transparency, and specificity in reporting future psychodrama and other psychotherapy research are discussed.
