Reach, Uptake, and Satisfaction of Three Delivery Modes of .

. FUEL Your Life (FYL) is a worksite translation of the Diabetes Prevention Program (DPP). In a randomized controlled trial, participants in a phone coaching condition demonstrated greater weight loss compared to participants in a group coaching or self-study condition. The purpose of this article is to describe the differences in participant reach, intervention uptake, and participant satisfaction for each delivery mode. . Employees who were overweight, obese, or at high risk for diabetes were recruited from city-county governments. Process evaluation data were collected from health coach records, participant surveys, and research team records. Differences between groups were tested using Pearson chi-square test and one-way analysis of variance. . Employee reach of targeted enrollment was highest for the self-study condition. Overall, intervention uptake was highest in the phone coaching condition. Participants who received phone coaching had increased uptake of the participant manual and self-monitoring of food compared to participants who received group coaching or self-study. . FYL demonstrated that DPP could be effectively delivered in the worksite by three different modalities. When implemented in a self-study mode, reach is greater but intervention uptake is lower. Phone health coaching was associated with greater intervention exposure.
