NC: Transtheoretical Model (2007)
Transtheoretical Model - A theoretical model of intentional health behavior change that describes a sequence of cognitive (attitudes and intentions) and behavioral steps people take in successful behavior change. The model, developed by Prochaska and DiClemente, is composed of a core concept known as Stages of Change, a series of independent variables, the Processes of Change, and outcome measures including decision balance and self-efficacy. The model has been used to guide development of effective interventions for a variety of health behaviors.
What is the evidence that nutrition counseling based on the Transtheoretical Model results in health or food behavior change in adults counseled in an outpatient or clinic setting?
One positive-quality intervention study strongly supported application of the Transtheoretical Model or Stages of Change in improving health and food behavior change. Much research has been accomplished to validate instruments used to measure stage of change in the dietary context. Additional research is needed to support its effective application in nutrition counseling.
