An Internet-delivered Intervention for Coping With ADHD in Adulthood - a Randomized Controlled Trial

ADHD in adulthood, with an estimated prevalence of 2 - 3 %, is associated with challenges in daily life functioning. The availability of evidence-based psychological interventions for adults with ADHD is poor. Interventions delivered over the Internet might help to increase the availability of effective psychological interventions for this group. The primary aim of this study is to examine the efficacy of a self-guided Internet-delivered intervention for coping with ADHD. The secondary aim is to investigate the effects of individual adaptation of the intervention on adherence, satisfaction and clinical outcomes. A minimum of 118 participants with a self-reported ADHD diagnosis will be included in the study. In phase 1 we will conduct a randomized controlled trial with two arms, 1) self-guided Internet-delivered intervention for coping with ADHD (N=59), 2) self-guided online psychoeducation (control group, N= 59), with a 3 month follow-up. After 3 months the second phase of the study starts. In this phase (II) the control group participants will receive an adaptive version of the Internet-delivered intervention. This includes adaptation of the order of the modules to the individual participant needs, with the use of rule-based and machine-learning based adaptation. Clinical outcomes in both phases are inattention, hyperactivity, quality of life and stress. Uptake, usage, adherence and satisfaction will be explored. Repeated measurers are at baseline, weekly during the intervention period, post-intervention and 3 months follow-up.
