How QbTest Works

QbTest is a test to evaluate the symptoms of ADHD for children and adults that combines motion-tracking analysis with a uniquely designed continuous performance task.

During the 15-20 minute task, the patient is instructed to respond as quickly and accurately as possible to certain geometric shapes appearing on a computer screen by pressing a responder button. As the patient performs the task, a camera located above the computer records movement from a reflector located on the patient's forehead.

The Importance of the  QbTest

QbTest is not meant to be a stand alone tool for diagnosing ADHD. Instead, QbTest is designed to be added to the assessment process along with clinical interview and rating scales. QbTests' objective data is an important corner of the diagnostic triangle, along with clinical interview and rating scales. By adding QbTest to the assessment and monitoring process you can get a better view of ADHD.


In fact in a study conducted on both children and adolescents, QbTest increased diagnostic accuracy when used during clinical assessment of ADHD as measured by subsequent rates of revised diagnosis over a 12-month period. In comparison to clinical procedure including clinical interview and rating scales alone, QbTest improved diagnostic accuracy by 20%.

When to Test with QbTest

During medication initiation and dosing changes to ensure efficacy


Periodically while off medication to determine the need for continued treatment
