The Transtheoretical Model (also called the Stages of Change Model) was developed by Prochaska and DiClemente in the late 1970s. This model focuses on the decision-making of the individual and is a model of intentional change. The Transtheoretical Model operates on the assumption that people do not change behaviors quickly and decisively. Rather, change in behavior, especially habitual behavior, occurs continuously through a cyclical process.

The stages in this model are as follows:

  1. Precontemplation
  2. Contemplation
  3. Preparation (Determination)
  4. Action
  5. Maintenance
  6. Relapse
