Summary

This study will test a smartphone chatbot called Wysa that delivers cognitive-behavioral therapy-based self-help for adults with eating disorders. 800 participants will use the chatbot daily for eight weeks. The goal is to see if this digital tool can reduce eating disorder symptoms and provide a scalable treatment option.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
Wysa chatbot (digital cognitive-behavioral therapy program)
What this could lead to
If successful, this could provide a low-cost, scalable treatment option for people with eating disorders who currently lack access to care.
What could go wrong
This is a Phase 2 trial, so results are preliminary. The chatbot may not be as effective as in-person therapy, and participants must have low suicidality and not be in current treatment, limiting who can join.
