Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This study evaluates the impact of computerized inhibitory control training on attention-deficit hyperactivity disorder (ADHD) symptoms and ADHD-linked neural signatures in children with ADHD. Children were randomly assigned to adaptive computerized training (n=20) or non-adaptive computerized training control (n=20) with identical stimuli and goals.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Both medication and cognitive behavioral therapy are effective treatments for many children, however, adherence to both medication and therapy regimes is low. Thus, identifying effective adjunct treatments for ADHD is imperative.

Previous studies exploring computerized training programs as supplementary treatments have targeted working memory or attention. However, many lines of research point to inhibitory control (IC) playing a central role in ADHD pathophysiology. IC abnormalities in children with ADHD have been evidenced both in behavioral performance on computerized tasks as well as in the structure and function of neural systems known to support IC function. Furthermore, these IC abnormalities have been linked to symptom severity.

Given findings that the most successful training interventions for children with ADHD are those that have implemented IC training along wtih working memory or attention and previous work demonstrating that IC is a central deficit for children with ADHD, it is surprising that no studies have sought to investigate programs that specifically target IC. Investigators hypothesize that training IC alone will decrease symptoms of ADHD, and information confirming this hypothesis would contribute to making training regimens for children with ADHD efficient by identifying the primary cognitive skill that requires intervention. To test this, they administer a randomized control trial of either adaptive of non-adaptive stop signal reaction time (SSRT) tasks to children with ADHD and assess effects of training on ADHD symptoms and neural activity.

Allocation Method

RANDOMIZED

Intervention Model

PARALLEL

Children were randomly assigned to adaptive treatment (n=20) or non-adaptive control (n=20) with identical tasks, stimuli, and goals. Children were instructed to train for 5 days a week (25m/day) for 4-weeks. All participants had between 10-20 training sessions at study completion.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Adaptive Inhibitory Control Training

Participants played a set of three modified stop-signal reaction time tasks designed by NeuroScouting, LLC at home for approximately 5 days a week (25 min/day) for 4-weeks. This condition involved real-time adaptive gameplay that increased in difficulty as performance increased.

Group Type EXPERIMENTAL

Adaptive Inhibitory Control Training

Intervention Type BEHAVIORAL

Playing computerized stop-signal reaction time tasks that had been modified to increase in difficulty as performance increased.

Non-Adaptive Inhibitory Control Training

Participants played a set of three modified stop-signal reaction time tasks designed by NeuroScouting, LLC at home for approximately 5 days a week (25 min/day) for 4-weeks. This condition had no change in difficulty (non-adaptive gameplay).

Group Type ACTIVE_COMPARATOR

Non-adaptive Inhibitory Control Training

Intervention Type BEHAVIORAL

Playing computerized stop-signal reactions time tasks that do not change in difficulty level (non-adaptive).
