QbCheck Objective ADHD Testing
FDA-cleared computerized testing platform we use in adult ADHD evaluation when objective measurement of attention, impulse control, and motor activity adds clinical value.
QbCheck is a 20-minute computerized continuous performance test with motion tracking. The patient watches a screen and responds to specific visual stimuli while the system measures attention, impulse control, and motor activity simultaneously. The result is objective data on the three core ADHD symptom domains.
QbCheck is FDA-cleared for adult ADHD assessment. We use it when objective testing would clarify the clinical picture — particularly in cases with subtle symptoms, diagnostic uncertainty, or when patients want objective documentation alongside clinical assessment.
What QbCheck Measures
Three core ADHD symptom domains, measured objectively over a 20-minute task.
Attention
Sustained attention over the 20-minute task. The system measures how consistently you respond to target stimuli, how often you miss targets, and how response patterns change over time as fatigue or attention drift sets in. Inattention is one of the core ADHD symptom domains, and QbCheck provides objective measurement against population norms.
Impulse Control
How often you respond to non-target stimuli (commission errors). Impulsivity is another core ADHD symptom domain — QbCheck measures the rate at which you respond when you shouldn't, which is one of the more reliable behavioral indicators of ADHD-related impulsivity.
Motor Activity (Hyperactivity)
Motion tracking via webcam captures fine motor movements during the test. The system measures total movement, frequency of fidgeting, and motion patterns. Hyperactivity in adults is often subtler than in children — adults learn to suppress overt hyperactivity but the underlying motor restlessness often remains. QbCheck captures this in a way clinical observation alone usually doesn't.
How QbCheck Fits Into Our Evaluation
QbCheck provides objective measurement on the three ADHD symptom domains — but it's not a standalone diagnostic tool.
What QbCheck does well:
Provides objective behavioral measurement of attention, impulsivity, and motor activity. Generates results comparable to age-matched and gender-matched population norms. Useful for documenting ADHD-related cognitive and behavioral patterns objectively. Helps differentiate ADHD from anxiety-driven attention problems (anxiety typically affects attention differently than ADHD does, in patterns QbCheck can reveal).
What QbCheck doesn't do:
It doesn't capture lived experience of having ADHD. It doesn't account for executive function challenges that don't show up in a 20-minute task. It doesn't differentiate ADHD from other conditions that can produce similar attention and impulse control patterns (severe sleep deprivation, untreated thyroid disease, certain medication effects). The clinical interview catches what QbCheck can't.
How we use it:
QbCheck generates one piece of evidence among several. We use the results alongside the clinical interview, developmental history, ASRS-v1.1 and Conners' rating scales, and any cognitive testing from Creyos. The integrated clinical picture is what produces the diagnostic formulation.
When We Use QbCheck
QbCheck isn't part of every ADHD evaluation. We use it when objective testing would add specific value.
When clinical picture suggests ADHD but rating scales are borderline
Some patients have clear clinical history of ADHD but score in borderline ranges on standard rating scales — sometimes due to high masking, high intelligence compensating for symptoms, or anxiety obscuring the underlying pattern. QbCheck can clarify the picture.
When patients want objective documentation
Some patients explicitly want objective testing — for ADA accommodations, university disability services, professional licensing, or simply for their own confidence in the diagnosis. QbCheck provides documentation that's objective, FDA-cleared, and easy to defend in formal contexts.
When differentiating ADHD from other conditions
Anxiety, depression, sleep disorders, and other conditions can produce attention problems that look ADHD-like in clinical interview. QbCheck data patterns are sometimes useful for differentiation — anxiety-driven attention problems often look different from ADHD attention problems on objective testing.

QbCheck Is Included in Your Evaluation Price
Many specialty practices charge separately for QbCheck testing — sometimes $200-$400 on top of the evaluation. We don't.
QbCheck is included in the price of your evaluation when we use it. ADHD evaluation $1,650. Autism evaluation $2,050 (when ADHD comorbidity assessment includes QbCheck). AuDHD evaluation $2,500 (where QbCheck is more frequently part of the assessment battery).
