Transtheoretical Model of Stages of Change
TRANSTHEORETICAL MODEL OF STAGES OF CHANGE
The transtheoretical model of intentional behavior change describes change as a process that unfolds over time and progresses through six stages: precontemplation (not ready to take action); contemplation (getting ready); preparation (ready); action (overt change); maintenance (sustained change); and termination (no risk of relapse). Progress requires the application of specific change processes such as consciousness raising (education and feedback) at the precontemplation stage and reinforcement and helping relationships during action. Tailoring public health programs to each stage of change can dramatically increase recruitment, retention, and progress and impacts on entire populations at risk for chronic disease and premature death.
