Prochaska and DiClemente (Transtheoretical Model)

The Transtheoretical Model by Prochaska and DiClemente describes how people change behaviors in stages. It includes five main stages: Precontemplation (not considering change), Contemplation (thinking about change), Preparation (getting ready), Action (making changes), and Maintenance (keeping changes). People move through these stages at different speeds, and understanding this helps tailor support. The model recognizes that change is a process, not a single event, and setbacks can occur, requiring ongoing effort. It’s widely used to guide interventions for habits like quitting smoking, exercising more, or improving health behaviors.
