  • What this is: a screening instrument. It estimates whether your day-to-day patterns are consistent enough with adult ADHD to be worth a professional conversation.
  • What this is not: a diagnosis, or anything close to one. Sleep, stress, mood, and ordinary life can produce the same patterns. Only a clinician who knows your history can tell the difference.
  • Privacy: your answers stay in this browser, on this device. They never enter your Portrait, your account, or any cross-test reading.
  • Answer for the last 6 months, and go with your first honest read of each question.

Part A — the screener

These six questions are the formal screen. They're the items found most predictive of an ADHD diagnosis, and they carry a published threshold.

Part B — context for your clinician

Twelve further questions. These don't change the screening result — they give your doctor a fuller symptom picture to read alongside it.

Please answer the highlighted questions — every item matters for scoring.
