About

The purpose of this study is to test two different approaches to helping individuals who have recently starting eating a healthful diet maintain those healthy changes. This study will deliver a health program using an automated telephone system. The programs will be designed to help individuals maintain a healthy diet change for a lifetime.

Full description

RCT is completed. However, the eligibility was 18 y/o or greater and living in Greater Boston area. The participants used an evidenced based dietary intervention for 3 months and then were randomized to 1 of 3 arms. Those in the experimental arm received a 6 mo intervention based on social cognitive theory or goal systems theory. The intervention was designed to help the participants maintain previously achieved changes in the their diet, e.g., fruits and vegetables. The outcome measures are fruit and vegetable consumption as measured by servings on multiple dietary measures as well as a 24 hr dietary recall.
