What is the QbCheck?

Introduction

It is a computer-based test that objectively measures the core signs of ADHD: Hyperactivity, Impulsivity and Inattention. During the test, a spacebar is used to respond to targets and motor activity is registered by a web camera. No images are captured during the test.

What do I do?

The test should be performed on a computer with a built-in web camera. During the test, a number of symbols are shown on the computer screen. The task is to push the space bar when a certain symbol appears on the screen. Meanwhile, a web camera uses facial recognition technology to track your movements during the test. The test takes 20 minutes to complete and is not dependent on your language, reading or mathematical skills.

Is the test accurate?

The QbCheck is well documented, widely used, and registered or cleared by all concerned authorities, including The European Medicines Agency (EMA) and The Food and Drug Administration (FDA).
