MyADHD: A therapist-guided internet-delivered intervention for adult ADHD — Results from a single-armed open clinical trial in routine care

In this open, single-arm study conducted in routine clinical care, therapist-guided internet-delivered treatment was associated with moderate improvements in ADHD symptoms and quality of life among adults with ADHD. Findings were comparable across baseline levels of comorbidity, treatment expectation and route to care. Given the absence of a control group, findings should be interpreted cautiously, and causal inferences cannot be drawn. Replication in adequately powered randomized controlled trials is needed to determine the intervention's efficacy and to clarify for whom and under what conditions it is most effective.
