Is this trial a fit for you?

What this trial studies

This study uses a randomized controlled design to evaluate GEARS, a group-based therapy aimed at improving emotion regulation in adults with ADHD. The trial includes an RCT comparing GEARS to a passive waitlist control and a qualitative interview component to capture patient experiences. Approximately 150 adults with ADHD will be enrolled from psychiatric outpatient clinics in Stockholm, receiving GEARS in groups of about eight. Outcomes will be measured before, after treatment, and at six and 12 months follow-up, with a secondary qualitative study interviewing 15–20 participants. If GEARS proves effective, it could be adopted more broadly to improve daily functioning and quality of life in adults with ADHD.

Why it matters

Potential benefit: If successful, GEARS could improve emotional regulation and everyday functioning for adults with ADHD.

How similar studies have gone: Prior work on GEARS shows promise, but this is a rigorous randomized study with a qualitative component to confirm effectiveness and explore patient perspectives.
