Brief summary
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.
Detailed 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.
Interventions
BEHAVIORALSocial Cognitive Theory
6 mo dietary intervention. This arm received an diet intervention designed to maintain changes in fruit and vegetable consumption. The intervention components were based on social cognitive theory.
BEHAVIORALgoal system theory
This arm received a 6 mo diet intervention designed to maintain changes in fruit and vegetable consumption. The intervention components were based on goal systems theory and delivered by an automated telephone system.

Design outcomes
Primary
| Measure | Time frame |
|---|---|
| The study hypothesis is that the goal systems intervention will out perform the social cognitive intervention and that both of these interventions will outperform the control group for fruit and vegetable consumption. | July 2006-July 2009 |
Secondary
| Measure | Time frame |
|---|---|
| Intervention effects will be mediated by behavioral factors predicted by Social Cognitive Theory and Goal Systems Theory. | July 2006-July 2009 |
