简要总结
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.
详细描述
In this study, 170 adults with eating disorders will take part. They will regularly report on their thoughts, feelings, and behaviors throughout the day. Based on this information, the program will send "just-in-time" support, which involves short, tailored suggestions that encourage the use of helpful coping skills right when they are most needed.
The study has three main goals:
- To better understand risk patterns:
The investigators will use real-time data to build personalized models that predict when someone is at higher risk for eating disorder behaviors based on their own data and patterns. 2. To test which therapy skills work best and why:
The investigators will examine how different evidence-based therapy skills (such as managing urges, improving mood, reducing strict dieting, and improving body image) help reduce eating disorder behaviors in daily life, and what psychological factors explain these effects. 3. To evaluate the program's usability:

研究组 & 干预措施
All Participants Receive Just-In-Time Adaptive Interventions (JITAIs) through the EDDI App
All participants will receive just-in-time adaptive interventions when their personalized model identifies that they are at risk for an eating disorder behavior. The content of the just-in-time adaptive intervention (i.e., the therapy skill targeted) will be randomized at the point of just-in-time adaptive intervention delivery.
