ASRS-v1.1 — Adult ADHD Self-Report Scale (full 18-item)
The ASRS-v1.1 was developed by the World Health Organization in collaboration with the Workgroup on Adult ADHD. The 6-item Part A is the validated screener; the 12-item Part B is a symptom-severity checklist that maps to DSM-5 inattention and hyperactivity-impulsivity domains.
This is a screening tool, not a diagnosis. A clinical evaluation is needed to confirm.
For each item, answer based on how you have generally felt and behaved over the last 6 months. Choose the response that best describes how you have been doing.
Part A — Screener Result

What this means: The ASRS-v1.1 is a screening tool, not a diagnostic instrument. A positive screen on Part A means symptoms are present at a level that warrants a fuller clinical evaluation, not that you have ADHD. Part B gives additional symptom information your clinician can use.
