Study Description

Promoting Lifestyle Change Via Tailored mHealth Feedback to Improve Health

The overall purpose of this randomized clinical trial is to examine the effect and efficacy of the individualized, real-time, smartphone-based feedback of diet and physical activity self-monitoring on subsequent weight-control behaviors, weight loss outcomes and sustainability of patient engagement. Participants will be randomized to one of 2 groups: (1) Self-Monitoring -similar to what many people do on their own, subjects will self-monitor diet, physical activity using Fitbit and weight using a Bluetooth-enabled scale, and (2) Self-Monitoring +Feedback-participants will self-monitor as described for the Self-Monitoring group but also will receive tailored Feedback messages. The Self-Monitoring +Feedback participants will receive up to 4 daily discrete pop-up Feedback messages on the participant's smartphone delivered at random times during waking hours and tailored to content of recorded entries in the subjects' smartphone-based diaries and a weekly summary Feedback message about the participant's weight.
