Transtheoretical Model

Also written as: TTM — Transtheoretical Model

A behavioral change model describing six stages of change from precontemplation to maintenance.

Full Definition

The Transtheoretical Model (TTM), also known as the Stages of Change model, is a theoretical framework that describes behavior change as a process involving six stages: precontemplation, contemplation, preparation, action, maintenance, and termination. The model emphasizes that people move through these stages at different rates and may cycle back to earlier stages. TTM includes additional constructs such as processes of change, decisional balance, and self-efficacy. In behavioral medicine, this model guides intervention timing and content to match the patient's readiness for change. Clinical applications often involve stage-matched interventions and motivational techniques.
