Answer six questions about the last six months to see whether your answers match the pattern the adult ADHD screener looks for.
Your answers
For each question, choose how often it has applied to you over the past six months.
Screening result: negative
Your answers do not match the pattern this screener looks for. That does not rule ADHD out — six questions cover only part of it — so if these difficulties are affecting your work, your studies or your relationships, talk to a doctor anyway.
This is a screening questionnaire, not a diagnosis. ADHD is diagnosed only by a psychiatrist or a clinical psychologist, after a full assessment. Nothing here is a recommendation for medication.
01
The questions are Part A of the World Health Organization's Adult ADHD Self-Report Scale — the short form used to decide whether a full assessment is worth arranging, rather than the assessment itself.
Scoring is per question, not a running total. Each item has its own threshold, and four or more items reaching their own threshold is a positive screen. Treating it as a flat "four answers of Often" rule is the usual mistake, and it misses the inattentive presentation, which is the one most often overlooked in adults.

Adult ADHD rarely looks like the classroom picture. Hyperactivity often turns inward — restlessness, a mind that will not settle — while the inattentive side stays and gets expensive: missed deadlines, unopened admin, a working memory that keeps dropping things.
What matters for a diagnosis is that the difficulties are long-standing, show up in more than one part of life, and cause real impairment. Everyone loses their keys occasionally; that is not what is being asked.
03
A six-question screener is a sorting tool. It is deliberately quick and deliberately over-inclusive, because its job is to decide who should be assessed properly — not to decide who has ADHD.
04
A diagnosis of ADHD is made by a psychiatrist or a clinical psychologist. The assessment is a structured clinical interview covering your history from childhood onwards, usually with rating scales and, where possible, an account from someone who has known you a long time.
A screening result is a reason to get assessed, not a diagnosis. These are the consultations that can take it further.

No, and no online questionnaire can. This is a screener: it sorts people into "worth assessing properly" and "not on these answers". A diagnosis is made by a psychiatrist or a clinical psychologist, from a full interview about your history rather than from six questions.
The Adult ADHD Self-Report Scale, developed with the World Health Organization. Part A is the six-question screener used here; the full scale has eighteen items. It is the most widely used adult ADHD screening instrument, which is why clinicians recognise the result you bring them.
Four or more of the six questions answered at or above that question's own threshold. The first three count from "Sometimes", the last three only from "Often" — the thresholds differ because the questions do, and a single flat cut-off would miss the inattentive presentation.
Yes. Six questions cannot cover a condition that presents differently at different ages and in different people, and the inattentive presentation in particular is under-detected — one reason women are diagnosed later and less often. If the difficulties are affecting your life, a negative screen is not a reason to stop asking.
A psychiatrist or a clinical psychologist, depending on the country. A GP is normally where the process starts: they take the history, rule out the conditions that mimic ADHD — thyroid problems, sleep disorders, anxiety, depression — and refer you on for the assessment itself.
No. The scoring runs entirely in your browser. Nothing you select is sent to our servers or saved.
It starts in primary care: your family doctor reviews your history, rules out the conditions that look like ADHD — thyroid, sleep, anxiety, depression — and refers you to mental health services. The diagnosis is made by a psychiatrist or a clinical psychologist, never by a questionnaire.
No. ADHD medicines are controlled and are started only after a full specialist assessment and a diagnosis. Our registered doctors can review a screening result, check for the conditions that mimic ADHD and refer you onwards; a diagnosis is not something a video consultation can give you.
Book a video consultation with a registered doctor, go through your history and the conditions that can look like ADHD, and find out what an assessment would involve.
