The role play is also an effective instrument for the practice in individual settings - whether in therapy, counselling or coaching. Based on current theoretical approaches, this book describes the framework, basic rules, instruments and techniques of one-person role-playing. It shows how some of the central role-playing techniques of psychodrama (e.g. empty chair, role reversal, mirroring, sculpture, role household) can be used effectively for diagnosis, problem clarification, resource activation, problem solving, behavioral training. Most important are decisive basic rules and instructions that turn a mediocre role play into a sustainable learning experience. For this reason, this book places special emphasis on the general conditions: How do I introduce a role play? How do I take on a role? What role do I play.
