New app aims to predict eating disorder behaviors before they happen
NCT ID NCT07600671
First seen Jun 27, 2026 · Last updated Jul 17, 2026 · Updated 5 times
Summary
This study is testing a smartphone app that uses brief surveys and phone sensor data to detect when someone with an eating disorder might be at higher risk for behaviors like binge eating, restricting food, or purging. The app then delivers short video lessons on coping skills. The goal is to see if the app can accurately predict these behaviors and be acceptable to users. 170 adults with eating disorders will use the app for 16 weeks.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- smartphone app with surveys, sensor data, and video modules
- What this could lead to
- If successful, this could lead to a digital tool that helps people with eating disorders get real-time support in their daily lives.
- What could go wrong
- This is an early-stage study focused on building and testing prediction models, not on proving treatment effectiveness. The app may not work for everyone or may have technical issues.
