Formula

Six items rated Never / Rarely / Sometimes / Often / Very Often for the past 6 months. Items 1–3 are positive at Sometimes, Often or Very Often; items 4–6 are positive at Often or Very Often. Count positive (darkly shaded) items, 0–6; ≥4 is a positive screen.

Clinical pearls

  • Attribution (required by the licence): ASRS Screener v1.1, © New York University and the President and Fellows of Harvard College; developed with the World Health Organization. The items may not be modified other than to create electronic versions.
  • A positive screen is not a diagnosis: DSM-5 adult ADHD needs symptoms before age 12, in two or more settings, with functional impairment, and other causes (anxiety, depression, sleep disorders, substance use) excluded.
  • In the original community validation the 6-item screener had sensitivity 68.7% and specificity 99.5% (Kessler 2005).

FAQ

How do you score the ASRS screener?

Count the answers that fall in the shaded boxes: Sometimes or more for questions 1–3, Often or more for questions 4–6. Four or more shaded answers is a positive screen.

Can the ASRS diagnose ADHD?

No. It is a screen. A positive result should lead to a full clinical evaluation of childhood onset, impairment and alternative explanations.
