Evaluating a Digital Cognitive Training Intervention in Adults With ADHD

Evaluating the Feasibility and Tolerability of a Digital Cognitive Training Intervention in Adults With ADHD: A Randomized, Placebo-controlled Trial

• Status: Not Yet Recruiting
• Phase: N/A
• Study type: Interventional
• Enrollment: 52 (estimated)
• Sponsor: McMaster University · Academic / Other
• Sex: All
• Age: 18 Years – 65 Years
• Healthy volunteers: Not accepted

Summary

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

Conditions

• ADHD

Interventions

Type	Name	Description
OTHER	Digital Cognitive Training	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.
OTHER	Digital Non-cognitive Training Intervention	This is a gamified computer platform lacking cognitive training components.
