ADHD: Quantitative Behavioural (QB) Test
What is a QB test?
A QB test is a computer based test that combines attention and impulse control measurements with activity recordings collected by an infra-red camera.
Your child’s results are compared with a group of children of the same age and gender, who do not have ADHD.
Why might my child be invited for a QB test?
As part of an overall assessment, QB test results provides valuable objective information to help determine if your child has ADHD or not.
How is the test performed?
This is a computer based test and takes 15-20 minutes, dependant on your child’s age.
The test equipment consists of an infra-red camera, a head band with a reflective marker and a response button. During the test a number of symbols are shown on a computer screen and the task is to push the button when a certain symbol and/or colour appears’ on the screen. Your child will receive instructions during the appointment.
Please note that the test is not dependent on the knowledge of English or a child's reading or mathematical skills, so this will not affect the result.
Please view the age-appropriate video below, which explains how the test is performed:
What happens if my child is unable to complete the QB test?
If your child is unable to complete the QB test, this will be discussed with you by the ADHD team.
What happens once the test has been completed?
You will not get results of the test immediately after it has been completed. QB test results along with additional gathered assessment information for ADHD, is looked at collectively.
All assessment information will be reviewed and this determines which of the following applies to your child:
- they may not meet criteria for ADHD diagnosis so you will be informed of this and they will be discharged from our service;
- they may receive an appointment to discuss possible ADHD diagnosis;
- in some cases they may require a school observation;
- they may be referred to an alternative service.
