Evaluating a Digital Cognitive Training Intervention in Adults With ADHD

The goal of this clinical trial is to evaluate whether a digital cognitive training program can reduce symptoms of ADHD, improve executive functioning, and decrease problematic internet use in adults aged 18-65 with a diagnosis of moderate to severe ADHD. The main questions it aims to answer are: Can digital cognitive training improve executive function, and ADHD symptoms in adults with ADHD? Does digital cognitive training reduce problematic internet use in this population? Researchers will compare the digital cognitive training intervention group to a non-cognitive training digital platform to see if the training leads to greater improvements in cognitive and behavioral outcomes. Participants will: Complete an 11-week digital cognitive training program (3, 1-hour sessions/week) or placebo intervention (3, 1-hour sessions/week) Attend baseline, midpoint, and post-intervention assessments Participate in weekly check-ins to monitor engagement and tolerability
