Interventions

  • Digital Cognitive Training — OTHER
    This digital cognitive training program uses gamified tasks in order to enhance cognitive skills in an engaging manner using machine learning AI algorithms to target the intervention to individual cognitive skill deficits. It consists of personalized gamified cognitive tasks that target individual cognitive deficits associated with ADHD including attention, impulsivity, working memory, and cognitive flexibility.
  • Digital Non-cognitive Training Intervention — OTHER
    This is a gamified computer platform lacking cognitive training components.

Study Details

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

Arms

  • Experimental: Digital Cognitive Training
    Participants randomized to the intervention group will receive 1-hour cognitive training sessions three times weekly for 10 weeks. The digital cognitive training platform will consist of personalized gamified cognitive tasks that target individual cognitive deficits associated with ADHD including attention, impulsivity, working memory, and cognitive flexibility.
  • Placebo Comparator: Digital Non-cognitive Training Intervention
    Participants will use a control gamified computer platform matched for time but lacking cognitive training components. Participants will engage in this activity for 1 hour three times a week for a duration of 10 weeks.
