A transtheoretical model of behavior change is an analysis of the health behavior change process that draws on the stages and processes people go through in order to bring about successful long-term behavior change.
The stages include
- precontemplation,
- contemplation,
- preparation,
- action, and
- maintenance.
Successful attitude or behavior change at each stage depends on the appropriateness of intervention. For example, attitude-change materials help move people from precontemplation to contemplation, whereas relapse prevention techniques help move people from action to maintenance.
