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.
