NCT ID NCT07094503
First seen Jul 15, 2026 · Last updated Jul 16, 2026 · Updated 1 time
Summary
This study tests a digital chatbot program designed to prevent eating disorders in adolescents aged 13 to 19 who are at risk. Participants use the chatbot daily for three months to complete modules based on cognitive-behavioral therapy, focusing on body image and eating behaviors. The goal is to see if the chatbot can reduce weight concerns and related risk factors.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- a digital chatbot program called Wysa that provides cognitive-behavioral therapy-based guided self-help modules for eating and body image
- What this could lead to
- If effective, this chatbot could offer a scalable, accessible way to prevent eating disorders and improve mental health in teens.
- What could go wrong
- This is a relatively early-phase trial with 400 participants, so results may not apply broadly. The chatbot's effectiveness depends on daily engagement, which may be challenging for some users.
