  Purpose
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.

Condition Intervention Phase
Cancer Behavioral: Social Cognitive Theory Behavioral: goal system theory Phase 1

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Single (Participant)
Primary Purpose: Prevention
Official Title: Trial of 2 TeleComputer Diet Change Maintenance Programs

Further study details as provided by Robert H. Friedman, Boston Medical Center:

Primary Outcome Measures:
  • 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. [ Time Frame: July 2006-July 2009 ]

Secondary Outcome Measures:
  • Intervention effects will be mediated by behavioral factors predicted by Social Cognitive Theory and Goal Systems Theory. [ Time Frame: July 2006-July 2009 ]

Enrollment: 1049

Study Completion Date: July 2011
Primary Completion Date: August 2010 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: social cognitive theory
This arm received an diet intervention designed to maintain changes in fruit and vegetable consumption. The intervention components were based on social cognitive theory and delivered by an automated telephone system.
Behavioral: Social 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.
Other Name: Social cognitive theory (SCT)
Experimental: Goal Systems Theory
This arm received an diet intervention designed to maintain changes in fruit and vegetable consumption. The intervention components were based on goal systems theory.
Behavioral: goal 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.
Other Name: Goal systems theory (GST)
No Intervention: Comparison group
comparison group

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.
