First seen Jul 01, 2026 · Last updated Jul 02, 2026 · Updated 1 time
Summary
This study tests whether a smartphone app that delivers cognitive behavioral therapy (CBT) can help adults with social anxiety disorder. Participants use the app for 12 weeks, learning skills like cognitive restructuring and exposure exercises. The trial compares app users to a waitlist group to see if the app reduces social anxiety symptoms.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Smartphone-delivered cognitive behavioral therapy (CBT) app
- What this could lead to
- If effective, this app could provide a convenient, accessible treatment option for social anxiety disorder, reducing symptoms without needing in-person therapy.
- What could go wrong
- This is an early-stage trial with a small sample and a waitlist control, so results may not generalize. The app may not work as well as in-person therapy, and some people may not engage with it.
