App aims to stop anxiety and depression before they start
NCT ID NCT07185867
First seen Jun 24, 2026 · Last updated Jun 26, 2026 · Updated 1 time
Summary
This study will test whether a personalized smartphone app can help prevent anxiety and depression in adults who do not currently have these conditions. About 2,595 people in Spain and Chile will use either a highly interactive app (Pandora-1), a simpler educational app (Pandora-2), or receive usual care. The apps provide tips on exercise, sleep, relationships, and emotional well-being, and track progress over a year.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

- What this could lead to
- If successful, this could provide an effective, scalable way to prevent anxiety and depression using a smartphone app.
- What could go wrong
- The trial is not yet recruiting and results are years away. The app may not work for everyone, and adherence to the app could be low.
