The theory that a person progresses through six stages of change before achieving sustained behavior change is known as the transtheoretical model of behavior change.
The transtheoretical model of behavior change was developed in 1977 by James O Prochaska, Carlo Di Clemente, and colleagues. It uses various theories of psychotherapy to study the willingness of an individual to work on healthy behavior, strategies, and the process of change and development.
The transtheoretical model of behavior explains that change consists of progress at every stage of behavior therapy. There are six stages of change in behavior therapy. First is precontemplation where people are not ready to work for the behavioral intervention. The second stage is contemplation where people identify the need and prepare themselves to work on their behavior.
The third stage is preparation where people might begin with a few steps to change behavior and prepare for future intervention. The fourth stage is action where people make modifications in behavior. The fifth stage is maintenance where people maintain their efforts for some time. The sixth stage is termination where people have finally overcome the temptation of problematic behavior.
