Introduction and objectives: Adults with attention deficit hyperactivity disorder (ADHD) are more stressed, more often on sick leave, and receive sickness absence recommendations to a greater extent than adults without ADHD. This project evaluates the feasibility, acceptability, and effects of an internet-based stress-management program, developed specifically for this at-risk population.

Methods: The intervention is based on existing support and interventions for ADHD adults, and inspired by support and interventions for relevant psychological disorders. The development includes a thorough assessment of previous research. The most relevant and effective material is adapted to the internet format and the ADHD-adult population. The program is evaluated in a pilot study during the spring of 2023, and will later be tested in a randomized controlled trial.

Results: At the time of writing, 36 participants have recently started the intervention. Preliminary results are expected to be presentable at the 9th World Congress on ADHD in Amsterdam.

Discussion: Although adults with ADHD experience more stress and are more often on sick leave than their non-ADHD peers, there has been limited research on methods to manage and prevent these negative outcomes. If this stress-management program shows promising results, it could quickly be made available to caregivers and/or the public, possibly saving considerable resources for individuals, employers, and society.
