Peer groups have a great significance in children's development. Since children express their problems through play and action, Alfons Aichinger and Walter Holl have developed the basic ideas and intervention possibilities of psychodrama for group therapy work with children in a process spanning over 35 years. Using vivid examples, they describe the appropriate composition of a group of children, the structure of a group therapy session, the group process, disorder-oriented and group process-oriented interventions and the demands placed on the leaders of these groups.
