  • Intervention
    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?
    • Conclusion

      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.
