Psychodrama will help your emotional education. Some of us need experience working with deep and painful stories.

It will help you manage audiences. Moreno's theory of sociometry is of great value to playback theatre practitioners.

It will help you understand what a story is.

Furthermore, some psychological education, whether of psychodrama or another method, is valuable to help you recognize therapeutic issues that may come up during the spontaneous playback theatre process.
