About this trial

This study will evaluate if a specific treatment for emotion regulation in ADHD, GEARS, effectively reduces symptoms of emotional dysregulation. GEARS will be evaluated through a randomized controlled trial (RCT) and a qualitative interview study.

This project aims to investigate two main questions:

1. Is GEARS an effective treatment for emotion regulation difficulties in adult ADHD patients? 2. How do participants perceive the impact of completing the GEARS treatment? Study 1 investigates research question 1 through an RCT comparing GEARS to a passive control group. Data are collected using validated measures before and after treatment/waiting period, as well as at six and 12 months follow ups.

Sample size: 150 participants, ensuring sufficient statistical power to detect significant between-group differences, even with some attrition.

Study 2 examines the patients' perspectives on the treatment by interviewing 15-20 participants about their experience with GEARS. The interviews focus on GEARS' perceived impact. Interviews will be recorded, transcribed, and analyzed using thematic analysis to identify key recurring themes.
