Attention Deficit Hyperactivity Disorder (ADHD) is a common neuropsychological disorder affecting 3-7% of all school aged children. About 30-50% of these children continue to have symptoms into adulthood.

ADHD can be described as a persistent or on-going pattern of inattention and/or hyperactivity-impulsivity that gets in the way of daily life or typical development.

With the proper diagnosis and treatment, many of the difficulties associated with ADHD can be significantly reduced and sometimes even eliminated.

What is QbTest?

QbTest is a FDA cleared and a CE marked computer based test that measures the core symptoms associated with ADHD including hyperactivity, impulsivity and inattention/distractibility. The test results are presented in a report that compares your results with a non-ADHD group of people of the same age and gender.

QbTest provides objective data that together with other information will help your clinician to identify, rule out and monitor ADHD.

QbTest can also provide valuable information when customizing treatment intervention based on your individual performance.

How is a QbTest performed?

The test is performed in front of a computer screen and is independent of your language, reading or mathematic skills. The test equipment consists of an infrared camera, a headband with a reflective marker attached to it and a responder button. The task depends on your age:

QbTest 6-12

The test takes 15 minutes and the task is to push the responder button when a grey circle appears on the screen.
QbTest 6-12

Press when the circle appears, do not press when the crossed over circle appears.

QbTest 12-60

The test takes 20 minutes and the task is to push the responder button when a symbol of both the same shape and color is repeated on the screen.
QbTest 12-60

Press at stimuli number 2, 3 and 4 in this example.

What do the results look like?

The two QbTest reports below show the results from one person without ADHD and one person with ADHD. Both are 18-year-old. The two graphs at the upper part of the reports show activity level and the third graph shows attention and impulsivity. The green circles represent correct presses and the red squares represent incorrect presses. The vertical position of the symbols show the reaction time. At the bottom of the report all test results are summarized.

18-year-old person with ADHD

An 18-year-old person assessed for suspected ADHD, performed the test to the right below. Compared to the person without ADHD, his activity level increased and his reaction time varied significantly during the test. This is typically seen in adults with ADHD, and together with observations and other clinical assessment tools can help confirm an ADHD diagnosis.

Most frequent questions and answers

No, the camera only collects information about how and where the marker has moved, and does not collect any images.

No, the test is not dependent on your knowledge of English. Nor will your reading or mathematical skills affect the test.

No, the symbols are designed so that most forms of color blindness do not affect the testing.

No, there is no link between video game experiences and test results. The test itself requires no computer knowledge or skill and should be seen as a task and not a video game.
Yes, the QbTest is well documented, widely used and cleared by all concerned authorities, including the FDA (registration numbers K122149, K040894 and K133382).
