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.

Active substance
Pandora-1 app (behavioral intervention with personalized feedback and modules on exercise, sleep, relationships, and emotional well-being)
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.
