Transtheoretical model: applications in the prevention and treatment of cancer.

In summary, the transtheoretical model may help guide the choice of the best intervention approach to use when working to change behavior that is important in the prevention and treatment of cancer. In using this model, it is important to identify the person's stage of readiness for change as well as each of the other key constructs of the model, including confidence and temptations, perception of pros and cons, and use of the processes of change. Knowledge of these factors will guide the choice of the best stage-matched interventions to help move the individual forward through the stages of change to achieve long-term maintenance of the desired behavior.
