Predicting Binge and Purge Episodes From Passive and Active Apple Watch Data Using a Dynamical Systems Approach
In Brief
An observational study evaluating Recovery Record for Binge-Eating Disorder and Bulimia Nervosa. Completed, enrolled 1,166 participants across 1 site.
Detailed Summary
The Binge Eating Genetics Initiative (BEGIN) is an observational study where individuals with binge-eating disorder (BED) or bulimia nervosa (BN) complete assessments about eating disorder history, current disordered eating behavior, and mood. Participants also provide active data on binge eating, purging, nutrition, and cognitions using Recovery Record on the Apple Watch. Passive sensor data are collected via native applications over a 30-day period in 1000 individuals with BED or BN. Investigators will combine longitudinal passive (Apple Watch) and active (Recovery Record) data to predict when patients are at high risk of binge eating or purging. Results will enable the deployment of real-time, in-the-moment, personalized signaling of impending binge or purge episodes that will interrupt automatic behaviors and empower patients to exert control over binge eating and purging by engaging in therapeutic alternatives.

Timeline
Interventions
Observational data will be obtained through participants entering data on disordered eating episodes, mood, and food in Recovery Record, an app to assist people in managing their eating disorder during the 30 days of the trial. In addition, participants wear an Apple Watch from which passive data (e.g., heart rate, activity, and geolocation) are collected.
