The ASRS v1.1 Part A screener (Adult ADHD Self-Report Scale) screens for adult ADHD over the past six months: 6 items rated Never to Very often. Scoring counts shaded items rather than summing points — items 1–3 count when rated Sometimes or higher, items 4–6 when rated Often or higher — and 4 or more shaded items is a positive screen. This page is a quick-reference tool for licensed clinicians and trainees.

Rows highlight automatically when a response meets that item's shading threshold (items 1–3: Sometimes or higher; items 4–6: Often or higher).
| Shaded items | Interpretation |
|---|---|
| 0–3 | negative ADHD screen (<4 shaded) |
| 4–6 | positive ADHD screen (≥4 shaded) |
Unlike sum-scored screeners, the ASRS v1.1 Part A score is the number of items answered at or above that item's threshold (the shaded boxes on the paper form). Items 1–3 are shaded at “Sometimes,” “Often,” or “Very often”; items 4–6 are shaded at “Often” or “Very often.” Four or more shaded items indicates symptoms highly consistent with adult ADHD and warrants further clinical investigation.
Screening scores are not a diagnosis. Interpretation requires clinical judgment by a licensed professional. Results shown here are score ranges and severity categories only. This page is a quick-reference tool for licensed clinicians and trainees — it is not intended for self-diagnosis or for use by the general public, and it is not medical or clinical advice.
