Important: This tool supports, but does not replace, clinical judgement. A positive screen is not a diagnosis of ADHD — it indicates that symptoms are clinically significant and full diagnostic assessment by a qualified clinician is recommended. Validated for adults aged 18+.

Part A — Screener (Questions 1–6)

Positive screen = 4 or more items above threshold

Q1–3 threshold: Sometimes or above Q4–6 threshold: Often or above

Part B — Additional symptoms (Questions 7–18)
