What is the trans-theoretical model?

The Trans-Theoretical Model (TTM), also known as the Stages of Change Model, is a psychological framework that outlines the stages individuals go through when changing a behavior. These stages include Precontemplation, Contemplation, Preparation, Action, and Maintenance. The model emphasizes that change is not linear and individuals may progress through these stages at different rates or may relapse before achieving lasting change. TTM is widely used in health promotion and behavior change interventions.
