ADHD Evaluations with QbCheck
What is QbCheck?
QbCheck is an FDA-cleared test measuring all 3 core symptom domains; hyperactivity, impulsivity, and inattention. QbCheck is used when evaluating ADHD symptoms and measuring response to ADHD treatment.
QbCheck involves a 15 or 20-minute computer-based task that measures your (or your child’s) ability to maintain attention and impulse control. Meanwhile, an your computer’s camera tracks movements, and therefore activity, during the test. The results are based on a comparison of your (or your child’s) performance with data from other people of the same sex and age who do not have ADHD.
Why test for ADHD?
Adding objective ADHD technology can help to:
1. Improve diagnostic accuracy
2. Shorten time to diagnosis
3. Capture treatment response not reflected by rating scales
What should you expect?
A diagnostic assessment for ADHD involves three main parts: gathering a clinical history through an interview with your provider, an objective measurement of symptoms using QbTest, and the completion of one or more rating scales.
What does the test set-up look like?
The test equipment consists your PC or Mac with a web camera which you can access online in the conform of your home. A link will be sent to you by your physician when it is time for you take your test. You can do so on your own time and convenience. When the time comes for you to take that test it is recommended that:
- You are in a quiet room with no distractions
- Any windows and blinds are closed
- Clutter or any visual distractions are removed
- All other electronic devices are turned off
- People in close proximity to the test room to remain quiet
- Give you a seated stool without wheels or armrests (so excess movement is not recorded)
What do QbCheck results look like?
You results (left) are placed side-by-by with the result of a control group (right). The right side is the average compilation of individuals without ADHD standardized to your age and sex-assigned-at-birth.
How should I prepare for a QbCheck?
• Try to ensure adequate sleep the night before the test.
• Avoid consuming excessive amounts of caffeine the day of the test.
• If you are to be tested while on ADHD medication, please ensure that you take the medication as directed and let your physician know.
• For a child, explain that they will be taking a test on a computer which is designed to be boring. Inform the child that that it does not hurt. They will be seated in a room by themselves, but a family member can stand outside if helpful.
When will I receive my results?
The raw data (seen above) is available immediately to your clinician who will review and help you interpret the data.
