What is considered the final phase of the Trans-theoretical Model?

The final phase of the Transtheoretical Model is Termination or Adoption. This phase is where individuals have successfully maintained their behavior change for a significant period and no longer feel tempted to revert back to their old habits. The focus here is on the establishment of a new behavior as a permanent part of their lifestyle, which indicates a high level of confidence and stability in the change made.

In this phase, individuals demonstrate a complete integration of the new behavior into their daily life, wherein the risks of relapse are minimal. It stands apart from earlier stages of the model, such as Preparation, where individuals are still planning to make changes, or Contemplation, where they are considering changes but haven't yet acted on them. The Action phase is critical but serves as a precursor to achieving Termination or Adoption. Hence, achieving this final phase represents the culmination of the change process in the Transtheoretical Model.
