What this ADHD test measures

The ASRS-v1.1 was developed with the World Health Organization to help adults recognise whether their difficulties with attention, organisation, restlessness and impulsivity are frequent enough to be worth a proper clinical look. Questions 1–6 (Part A) are the screening questions: they were chosen because they best separate adults who go on to be diagnosed with ADHD from those who don't. Questions 7–18 (Part B) don't change your score, but they describe the fuller picture a clinician will want to explore with you.

ADHD in adults often looks different to the childhood stereotype. Instead of visible hyperactivity, it can show up as chronic lateness, unfinished projects, mental restlessness, difficulty switching off, impulsive decisions, or exhaustion from holding everything together. Many people are only identified in adulthood, often after a child in the family is assessed.

Please answer honestly — choose the option that best describes how you have felt and behaved over the past 6 months. Questions 1–6 are mandatory.

How are ASRS-v1.1 scores interpreted?

  • · A Part A positive score of 4–6 suggests the presence of ADHD symptoms.
  • · A Part A positive score below 4 suggests an absence of ADHD symptoms.
  • · The first 6 questions can identify almost 70% of people with ADHD.
  • · ASRS-v1.1 is a screening tool. Only a qualified specialist can make an ADHD diagnosis.

What happens after the test

Whatever your score, this questionnaire is a starting point rather than an answer. If your result suggests ADHD symptoms, the next step is a specialist assessment: a structured clinical interview covering your symptoms now and in childhood, how they affect work, study, relationships and daily life, and whether anything else — anxiety, low mood, sleep problems, trauma — explains the picture better.

  3. 3Your report and next stepsA written outcome explaining whether ADHD is diagnosed, and what support options are open to you.

A negative result doesn't always mean no ADHD

Some people score below the threshold and still have ADHD — particularly those with a mainly inattentive presentation, people who have built strong coping strategies, and women, who are more likely to be missed because their symptoms are quieter and internalised. Equally, a positive screen doesn't confirm ADHD: stress, poor sleep, anxiety and thyroid problems can all produce similar difficulties. That's exactly why a clinical assessment exists.

Frequently asked questions

Is this online ADHD test free?

Yes. The screening is completely free, gives an instant result on screen, and does not require sign-up, payment or an email address.

How accurate is the ASRS-v1.1 ADHD test?

The six Part A questions were selected by the World Health Organization workgroup as the items most predictive of adult ADHD, and identify a large proportion of adults who go on to receive a diagnosis. It is a screening questionnaire, not a diagnostic test, so a positive or negative result should always be followed by a specialist clinical assessment.

Can this test diagnose ADHD?

No. No online questionnaire can diagnose ADHD. A diagnosis requires a full clinical assessment with a qualified specialist, covering your developmental history, current symptoms, how they affect daily life, and other conditions that can look similar.

Does this ADHD test work for children?

No. The ASRS-v1.1 is validated for adults aged 18 and over. For children and young people we use age-appropriate rating scales as part of our child ADHD assessment.

What should I do if I score 4 or more?

A positive screen means your symptoms are worth exploring properly. The next step is a specialist ADHD assessment, where a clinician reviews your history in depth and confirms or rules out ADHD.

Is my answer data stored?

No. The questionnaire runs entirely in your browser. Your answers are not sent to us or saved anywhere, and disappear when you close the page.

How long does the ADHD test take?

Most people finish all 18 questions in about five minutes. Only questions 1 to 6 are required to get your score.
