title: Transtheoretical model text: levels of change, etc. Several self-help books—"Changing for Good" (1994), "Changeology" (2012), and "Changing to Thrive" (2016)—and articles in the news media 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". James O. Prochaska of the University of Rhode Island, and Carlo Di Clemente and colleagues developed the transtheoretical model beginning in 1977. It is based on analysis and use of different theories of psychotherapy, hence the name "transtheoretical". Prochaska and colleagues refined the model on the basis of research that they title: Transtheoretical model text: 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. The model is composed of constructs such as: stages of change, processes of change, levels of change, self-efficacy, and decisional balance. The transtheoretical model is also known by the abbreviation "TTM" and sometimes by the term "stages of change", although this latter term is a synecdoche since the stages of change are only one part of the model along with processes of change, title: Transtheoretical model text: 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.
