About this tool
Common questions
The Adult ADHD Self-Report Scale (ASRS-v1.1) is an 18-item questionnaire developed by the World Health Organization and validated in large clinical studies. Part A (questions 1–6) has the highest predictive value. It is widely used as a first-step screening tool by GPs and psychiatrists.
Yes. ADHD is commonly diagnosed in adults, and many people reach adulthood without a formal diagnosis. In adults, inattention is often more prominent than hyperactivity. Symptoms can affect work performance, relationships and daily functioning.
A high score does not confirm ADHD. It suggests speaking with a professional is worthwhile. Start with your GP, who can refer you to a psychiatrist. Alternatively, Sicknote.com can issue a private referral letter to a psychiatrist within hours, from £29.
No. This quiz runs entirely in your browser. Your answers are never sent to any server and nothing is stored or tracked.
You can use your result as supporting context when speaking to a GP or psychiatrist. However, Sicknote.com referral letters are based on a clinical questionnaire reviewed by an GMC/GMC-registered GP — not on this self-check result alone.
