Self-screener

ADHD adult self-screening questionnaire

The Adult ADHD Self-Report Scale (ASRS-v1.1), a validated screening tool developed with the World Health Organization. Runs entirely in your browser. Nothing you enter is stored or sent anywhere.

This is not a diagnostic tool. A positive result means it may be worth speaking to your GP. It does not mean you have ADHD. A negative result does not rule ADHD out. This screener is for adults aged 18 and over.

About the ASRS-v1.1

The ASRS-v1.1 was developed by Dr Ronald Kessler of Harvard Medical School in partnership with the World Health Organization. It is one of the most widely used adult ADHD screening tools in the world and is referenced in NICE guideline NG87.

The screener has 18 questions in two parts. Part A (6 questions) is the most predictive of ADHD in adults and is what clinicians focus on. Part B (12 questions) provides additional context.
