Prochaska and DiClemente's Stages of Change Model

Prochaska and DiClemente's Stages of Change Model describes the typical steps individuals go through when modifying a behavior. It includes five stages: Precontemplation (not considering change), Contemplation (thinking about change), Preparation (getting ready to change), Action (actively changing behavior), and Maintenance (sustaining the change). People may move back and forth between these stages. The model highlights that change is a process, not an event, and understanding one's current stage helps tailor effective support or interventions to facilitate lasting change.
