Eksperimentel: Standard
Those randomized to the Standard condition will record everything they eat and will total their daily fat grams and calories on the "Keeping Track" form used in the DPP.
They will turn in their self-monitoring diaries and download their accelerometer (but not see those data) at weekly group sessions 1 through 8. Thereafter they will be expected to turn in paper data monthly, in person at the months 3 and 6 assessments and via mail, fax or e-mail for months 4 and 5. Accelerometer data will be downloaded at in-person visits.

Eksperimentel: Technology Supported condition
Those randomized to the Technology Supported condition will record dietary intake and weight on the smartphone, using the user-friendly, persuasive interface developed in Phase I.
They will be expected to enter their dietary intake into the smartphone daily throughout the day.
They will also be expected to enter their weight and to wear the accelerometer daily.
Time-stamped data from the smartphone will upload automatically to the study server throughout the day, where it will be visible to the lifestyle coach.
The participant's real-time diet, activity, and weight data relative to goals will also be visually depicted on the participant's smartphone.
The anticipated web platform will be developed specifically for the ENGAGED participants.
The coach will provide feedback on diet and activity self-monitoring and goal adherence at least weekly by phone, e-mail or text during weeks 1-8 and then at least monthly through the 6 month follow-up.

Ingen indgriben: Self-Guided
Participants in the Self-Guided condition will receive DPP DVDs (3 DVDs and 1 CD) at the beginning of the study.
This condition will not receive any direct dietary or physical activity interventions outside of the DVDs.
Although Self-Guided participants will be receiving the same 7% weight loss goal as the other two groups, they will not be receiving physical activity or diet goals.
The DVDs cover the initial 12-weekly sessions of the DPP, with the sessions portrayed by professional actors.
They will also be provided with a supplemental DVD which includes a manual for each of the 12 sessions.
They will also be giving the Keeping Track booklets and asked to record their diet and activity daily.
