The QbTest is a computer-based test for assessing ADHD symptoms like hyperactivity, impulsivity, and inattention. It takes 15-20 minutes, with results available shortly after completion. The test, costing between £23 to £96, combines a continuous performance test with a measure of motor activity. It's used for both assessment and evaluation of treatment responses in ADHD [NICE, The Organizer UK, ADHD Foundation].
