Cancer Prevention Mastery Model Internet Intervention


OBJECTIVES:

- Compare the efficacy of an internet-based mastery-model health behavior educational
intervention vs internet-based standard care health behavior educational intervention
in improving physical activity and nutrition in sedentary participants with a higher
body mass index.

- Compare the efficacy of these interventions in reducing cancer risk, in these
participants.

OUTLINE: This is a randomized, controlled, multicenter study. Participants are stratified
according to participating site, age (55 years and over vs under 55 years), gender, ethnic
group, and aerobic capacity (≤ 6 metabolic equivalent tasks [METS] vs > 6 METS).
Participants are randomized to 1 of 2 intervention arms.

- Arm I (mastery model health behavior educational intervention): Participants log on to
the Guide to Health Project (GTH) website weekly and are provided access over a
24-month period to healthy lifestyle coaching modules and a completely individualized
fitness program organized according to a mastery-model health behavior educational
intervention. The mastery-model intervention comprises a 6-month behavioral initiation
phase that includes an orientation and refinement of goals and expectations for each
content area; a 6-month behavioral establishment phase comprising healthy lifestyle
coaching modules focusing on physical activity and nutrition at least once a week; and
a 6-month behavioral maintenance phase comprising a taper in the frequency of coaching
sessions to once a month.

- Arm II (standard care health behavior educational intervention): Participants log on to
the GTH website weekly and are provided access over a 24-month period to information
regarding a healthy lifestyle focusing on physical activity and nutrition organized
according to a standard care health behavior educational intervention.

In both arms, participants verify step-counts measured by a pedometer and complete the Block
Food Frequency Questionnaire online at 10 and 18 months.

PROJECTED ACCRUAL: A total of 300 participants (150 per arm) will be accrued for this study
within 1 year.
