Official title
Rapid Innovation of Precision Psychiatry Interventions Using Dynamic Systems Modeling and Ecological Quasi-Experiments
Overview
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.
Detailed description
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:
1. 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:
The investigators will assess whether participants find the digital support helpful, easy to use, and acceptable in their daily routines.
Interventions
- Behavioral 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
