Facilitating change in the behavior of clients to encourage effective and consistent oral self-care behaviors has been a main focus in the delivery of dental hygiene care. The Transtheoretical Model proposes that individuals progress through a series of stages when intentionally changing a behavior. Individuals utilize stage specific processes of change. The level of decisional balance and self-efficacy of an individual impact progression through the stages. This paper reviews the development of the Transtheoretical Model, presents a description of the model, and provides suggested applications for dental hygiene practice.
