NCT ID NCT07228650
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tracks 250 teens with ADHD aged 16-17 over two years using smartphone apps and a Fitbit. The goal is to understand what changes happen during this transition and what predicts negative outcomes. Researchers will then co-design a smartphone app with teens to help them manage their ADHD and stay engaged with healthcare.
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 lead to a smartphone app that helps young people with ADHD manage their condition and stay connected with healthcare during the transition to adult services.
- What could go wrong
- This is an observational study, not a treatment trial. It will not directly test any drug or therapy, and the app prototype may not be effective in real-world use.
