How the scoring works

Part A is the validated screener: each of the six questions counts as a flag when your answer reaches that question's clinical threshold (for some questions that's "Sometimes," for others "Often"). Four or more flags in Part A means your symptoms are highly consistent with adult ADHD and a full evaluation is warranted. Part B has no official cutoff — clinicians read it as supporting detail about how symptoms show up across your life.

What this test can and can't tell you

What it can do: tell you, in two minutes, whether your experience fits the pattern that deserves a professional look — and give you something concrete to bring to an appointment.

What it can't do: diagnose you. Plenty of things can mimic ADHD — anxiety, depression, sleep deprivation, thyroid problems — and ADHD loves to travel with other conditions. Sorting that out is exactly what a psychiatric evaluation is for. A negative screen isn't a verdict either: quieter, inattentive presentations (common in women) sometimes slip under the threshold.

Frequently asked questions

Is this an official ADHD test or a diagnosis?

No. It's an unofficial, educational adaptation of the ASRS v1.1 checklist. It screens for symptoms consistent with adult ADHD; only a qualified clinician can diagnose ADHD after a full evaluation.

How accurate is the ASRS screener?

The six-question Part A was developed by the WHO workgroup and performed well in validation studies at identifying adults whose symptoms are consistent with ADHD. Like every screen, it can miss people and it can flag people who turn out not to have ADHD — that's why results always deserve professional follow-up rather than self-diagnosis.

What should I do if I screen positive?

Print or save your results and bring them to an evaluation — they make the first appointment more productive. If you're in California or Oregon, you can start with a free 15-minute call at this practice.
