Can a phone app ease depression and anxiety? massive new study aims to find out
NCT ID NCT06692842
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study will test a smartphone app called CONEMO in over 12,000 adults visiting primary care clinics. The app uses cognitive behavioral therapy techniques to help reduce symptoms of depression, anxiety, and insomnia. Participants will use the app on their own phones or tablets, and researchers will track whether their symptoms improve over time.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- CONEMO app (cognitive behavioral therapy-based digital intervention)
- What this could lead to
- If successful, this could provide an accessible, low-cost digital tool to help manage common mental health symptoms in primary care settings.
- What could go wrong
- This is an implementation study, not a new treatment test. The app's effectiveness for anxiety and insomnia is less established than for depression, and results may vary by user engagement.
