Support groups as open systems: a model for practice and research

Despite the increasing of use of support groups to respond to the needs of people dealing with crises, life transitions, and chronic conditions, there is no conceptual framework to guide practice and research. On the basis of a review of the literature, this article distinguishes support groups from self-help and treatment groups. It then proposes an open systems model for understanding the factors that affect support groups, for guiding interventions, and for evaluating their outcomes. Four conceptual dimensions are described: (1) environmental conditions (resources and constraints), (2) participant group characteristics (size, composition, and technology), (3) group conditions (goals, structural form, and development), and (4) outcomes (positive and negative effects for members, leaders, and organizations; group problems; and ethical and legal issues). Findings from a pilot study of support group practice based on this framework are presented and discussed.
