What Is This Adult ADHD Test?

This page uses the Adult ADHD Self-Report Scale (ASRS v1.1) — an 18-question symptom checklist developed by the World Health Organization and Harvard researchers. It is one of the most widely used adult ADHD screening tools in the world and is designed to help you recognise patterns of inattention and hyperactivity-impulsivity that may be worth discussing with a doctor.

Part A — Predictive Symptoms

The first 6 questions cover the symptoms most strongly associated with adult ADHD. Your answers here give the clearest early indication of whether a fuller assessment is worthwhile.

Part B — Symptom Frequency

The remaining 12 questions explore how often you experience attention and impulse-related difficulties at work, at home and in social situations. Your score is out of 48.

Important: This screener cannot diagnose ADHD. Many conditions can mimic ADHD symptoms, and only a qualified psychiatrist can make a formal diagnosis. Think of this test as a structured first step — it gives you and your GP a clear, evidence-based starting point for a conversation.

Understanding Your Result

Part A — Significant Indicators (0 to 6)

Questions 1 to 3 count as significant when you answered Sometimes, Often or Very Often. Questions 4 to 6 count as significant when you answered Often or Very Often. Consistent with the ASRS v1.1, four or more significant indicators suggests your symptoms are in a range where a conversation with a doctor is worthwhile.

Part B — Frequency Score (0 to 48)

The 12 Part B questions each score from 0 (Never) to 4 (Very Often). There is no single pass/fail cut-off — a higher score simply means you experience these difficulties more frequently. Bring both numbers to your GP consultation so they can put them in full clinical context.
