Adult ADHD Self-Report Scale (ASRS Screener)
The WHO 6-item screener for adult ADHD symptoms.
About this test
The ASRS screener is the World Health Organization's 6-item check for adult ADHD symptoms over the past six months. Each item has a threshold answer; four or more marked answers suggest symptoms consistent with ADHD and a reason for a full evaluation.
What your score means
| Score | Interpretation |
|---|---|
| 0–3 | Below screening threshold |
| 4–6 | Consistent with ADHD |
About this questionnaire
The ASRS-v1.1 is a freely available screening questionnaire. We present it exactly as published and add a plain-language explanation of your result.
It is for education and self-reflection, not a diagnosis — a score is a snapshot, not a label. If your result worries you, talk to a qualified professional. See how we choose and check our tests and our editorial standards.
