Eating Disorder Dynamic Intervention
Sponsor: Trustees of Dartmouth College
Summary
The goal of this study is to develop and test a digital program to help people with eating disorders in their everyday lives. The program uses brief surveys and sensor data collected by smartphones to understand when someone may be at higher risk for behaviors like restricting food, binge eating, or using unhealthy weight control behaviors.

Eating Disorder Dynamic Intervention
Participants will use a smartphone-based program designed to support eating disorder recovery in daily life. Participants will complete brief surveys about their mood, thoughts, and behaviors, and the smartphone will also passively collect activity-related data. This information is used to detect times when a person may be at higher risk for eating disorder behaviors. Participants will watch 4 video modules that introduce the core enhanced cognitive-behavioral therapy skills for eating disorders (reducing dietary restraint, urge management, emotion regulation, and improving body image), provide rationale, and prompt participants to complete interactive activities to practice these skills. Participants will then receive micro-randomized JITAIs prompting them to use these skills in their daily lives; micro-randomization will be used to deliver a JITAI from one of the 4 skill categories (reducing dietary restraint, urge management, emotion regulation, improving body image) or no JITAI.
