This document discusses stages of change and reactance in group work. It summarizes the stages of change model, which developed from research on smoking cessation and may apply to other issues. The stages are precontemplation, contemplation, preparation, action, and maintenance. It also discusses the common factors model and how relationships, motivation, capacities, skills and techniques, and external factors influence change. Reactance is defined as a response to threatened behaviors and can block change. Maintaining change requires attention to relationships and external environments to feel understood, connected, and safe.
