title: Applying exercise stage of change to a low-income underserved population.
abstract: OBJECTIVE
  To validate the transtheoretical model for exercise behavior and the constructs of decisional balance and self-efficacy for exercise in a low-income, poorly educated primary care sample.
  
  
  METHODS
  Patients attending public primary-care clinics from 4 separate sites in Louisiana were interviewed regarding their health behaviors.
  
  
  RESULTS
  The data provide equivocal support for applying the transtheoretical model for exercise and integrating it with other models of behavior change within this population.
  
  
  CONCLUSIONS
  Further studies modifying the decisional balance measures are necessary before definitive statements regarding the applicability of these models to exercise within this specialized population can be made.
