Transtheoretical model

The transtheoretical model of behavior change is an integrative theory of therapy that assesses an individual's readiness to act on a new healthier behavior, and provides strategies, or processes of change to guide the individual.[1] The model is composed of constructs such as: stages of change, processes of change, levels of change, self-efficacy, and decisional balance.[1]

Stages of change, according to the transtheoretical model.

The transtheoretical model is also known by the abbreviation "TTM"[2] and sometimes by the term "stages of change",[3] although this latter term is a synecdoche since the stages of change are only one part of the model along with processes of change, levels of change, etc.[1][4] Several self-help booksChanging for Good (1994),[5] Changeology (2012),[6] and Changing to Thrive (2016)[7]—and articles in the news media[8] have discussed the model. It has been called "arguably the dominant model of health behaviour change, having received unprecedented research attention, yet it has simultaneously attracted criticism".[9]
