Why it helps
Why we use an objective test
Checklists ask how you feel. QbCheck shows how you do on a real task.
It adds hard data to what you tell us.
It measures movement, not just focus.
It compares your results to adults your age and sex.
It gives a second view when your history is hard to read.
It can be repeated later to check how treatment is working.
It's quick, about 20 minutes.
QbCheck is one part of your evaluation, never the only part.
What it measures
Three things ADHD affects
During the test, you watch shapes on a screen and press the space bar when you see a target. Your laptop's webcam tracks small movements of your head. No pictures or video are saved.
What it can't do
- Diagnose ADHD on its own
- Replace a full clinical interview
- Rule out other conditions
- Show how ADHD affects your daily life
What it measures
- Attention: how well you stay on task
- Activity: how much you move while you work
- Impulse control: how often you respond too fast
- Your results next to adults your age and sex
- A clear report we go over with you
