Trans-Theoretical Model

This study evaluated the continuity of intermediate behaviors across the Stages of Change according to the Trans-theoretical Model. Behaviors were analyzed for adolescents switching to a low-fat diet in the UK. While diet and planned behaviors improved linearly, ambivalence increased towards the preparation stage and was reduced as participants moved through action and maintenance. Authors emphasize the need to retain motivation and vigilance towards relapse to ensure successful behavior change.
