Psychodrama is a therapeutic technique developed in the 1930s involving role playing and dramatic enactments to help clients gain insight and behavioral skills. It allows clients to explore problems by acting out scenarios in a safe environment. The key elements are a protagonist, auxiliary roles, audience, director, and stages of warm up, enactment, and discussion. Techniques include role reversal, doubling, and future projections. While effective, it requires trained facilitators and may not be suitable for all clients or settings.
