Could a smartphone app help diagnose ADHD?
NCT ID NCT07220330
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study is testing a smartphone app called QbMobile that measures attention, impulsivity, activity, and movement patterns. Researchers want to see if it can provide objective data to help diagnose ADHD in people aged 6 to 60. The study includes 700 participants with and without ADHD, and compares the app's scores to standard diagnostic methods.

- What this could lead to
- If successful, this could provide a reliable, objective tool to help doctors diagnose ADHD more accurately, both in clinics and remotely.
- What could go wrong
- This is an early validation study, not a treatment trial. The app may not prove accurate enough for widespread clinical use, and results may not apply to all populations.
