Summary
The purpose of this research was to develop and test the feasibility of Habit, a weight loss mobile application that was designed to coach patients through their weight loss challenges. In a pilot trial in 43 obese participants, investigators tested the feasibility of the Smart Coach mobile application when paired with a shortened online-delivered (8-week) behavioral weight loss intervention. Feasibility outcomes included frequency and duration of usage of the mobile app and each feature, recruitment, and retention. Post-intervention focus groups discussed the feasibility and acceptability of the intervention. The investigators also performed exploratory analyses comparing conditions on problem solving skills and weight loss at 8 and 16 weeks, which will inform a subsequent randomized controlled efficacy trial.
