The demonstration group: a tool for observing group process and leadership style.

Demonstration groups, a major modality for observing group process, have not been addressed in the group psychotherapy literature. This article defines the demonstration group and describes and discusses its various components: the volunteers (group members) and their recruitment, the demonstration group itself, group member debriefing, and the didactic component. Discussion of the physical setting, group agreements, and boundary considerations, as well as leadership tasks, challenges, and pitfalls are illustrated with examples.
