The document discusses three models of group work: 1) The social model prioritizes provision and prevention, addressing social problems in communities without hierarchy. The social worker acts as an enabler who stimulates social change and transfers leadership to members. 2) The remedial model is clinically oriented, supporting members to achieve individual change. It addresses dysfunction and helps maladjusted individuals improve relationships. The social worker motivates and drives the group. 3) The reciprocal model serves both individuals and society by recognizing their interdependency. It can include provision, prevention and restoration, viewing individuals as created and modified by relationships within systems.
