The transtheoretical model of behavior change: Implications for social work practice

The transtheoretical model of behavior change (TTM) can be used to help people to stop smoking and engage in other addictive behaviors. It has also been used on cancer prevention, HIV risk reduction, dietary change, exercise, occupational safety, and organizational change initiatives. TTM can be used with other therapies to assess an individual’s stage of change. This literature review examines the origins, actors, principles, applications, and evidence relevant to the development of TTM and the ways that it is being applied by members of the social work profession.
