Not sure if you have ADHD?

If you have ever wondered “how do I know if I have ADHD?”, this free ADHD check is a good place to start. It uses the Adult ADHD Self-Report Scale (ASRS-v1.1) Symptom Checker, developed with the World Health Organisation. Part A is the 6-question screener; Part B adds 12 optional questions for more detail. Answer about how you’ve felt over the last 6 months and we’ll show your result instantly. Ready Health will get a copy of your results, which they will store safely on file.

Part A
The ADHD screener — questions 1–6
These six questions are the ASRS-v1.1 screener and are the most predictive of ADHD. Please answer all six.
Part B
Symptom checklist — questions 7–18
Optional but helpful. Adds detail on symptom severity and day-to-day impact.

Please answer all 6 Part A questions and add your name, number and email so we can share your result.

When you submit, your answers and contact details are sent securely to Ready Health, who will store a copy of your results safely on file. They are used only to support your care. This checker is not a diagnosis.

The Adult ADHD Self-Report Scale (ASRS-v1.1) Symptom Checklist is a recognised screening tool only. A positive screen does not confirm ADHD, and a negative one does not rule it out — only a full clinical assessment can give you an answer. Developed in conjunction with the World Health Organisation.

Understanding your result

What the ADHD check tells you — and what it doesn’t

The ASRS-v1.1 is a screening tool that flags whether your experiences are consistent with ADHD. It is a useful first step, but it cannot diagnose ADHD. Here’s how to read your result.

Part A — the screener

Six questions shown by research to be the most predictive of ADHD in adults. Four or more “shaded” answers means your symptoms are highly consistent with ADHD and worth investigating further.

Part B — symptom detail

Twelve optional questions covering inattention, restlessness and impulsivity. They don’t change your screen result, but they help our clinicians understand severity and day-to-day impact.

A screen, not a diagnosis

A positive screen doesn’t confirm ADHD, and a negative one doesn’t rule it out. Only a full clinical assessment with a specialist clinician can give you a definitive answer.

Your next step

If your result suggests further investigation — or if these traits affect your daily life — you can book a full private ADHD assessment with no NHS-style waiting list.

Common signs of ADHD

What does ADHD look like?

ADHD affects attention, activity levels and impulse control, and it shows up differently from person to person. Recognising yourself or your child in these patterns — especially when they’ve been present for a long time and affect daily life — is often what prompts people to take a screening test.

Common signs of ADHD in adults

  • Difficulty concentrating, or losing focus on tasks that feel boring or repetitive
  • Struggling with organisation, planning and time management
  • Forgetfulness — missing appointments, deadlines or everyday tasks
  • Restlessness, fidgeting or feeling “driven by a motor”
  • Acting on impulse, interrupting others or finding it hard to wait
  • Difficulty regulating emotions, or feeling easily overwhelmed
  • Starting many things but struggling to finish them

Common signs of ADHD in children

  • Easily distracted and finding it hard to stay on task at school or home
  • Difficulty following instructions or finishing homework
  • Fidgeting, climbing or being unable to stay seated when expected
  • Talking excessively or blurting out answers
  • Difficulty waiting their turn or playing quietly
  • Losing things and appearing forgetful in daily activities
  • Acting without thinking about the consequences

These are common indicators, not a checklist for diagnosis. Many people experience some of these without having ADHD. A recognised screening test is a useful next step, and a full clinical assessment is the only way to confirm a diagnosis.

Common questions

Free ADHD check FAQs

How do I know if I have ADHD?
The only way to know for certain is a full clinical assessment, but a recognised screening tool is a sensible first step. This free ADHD check uses the WHO Adult ADHD Self-Report Scale (ASRS-v1.1) to flag whether your experiences of inattention, restlessness and impulsivity are consistent with ADHD in adults. If your result suggests it — or if these traits affect your daily life — the next step is a full ADHD assessment with a specialist clinician.
How accurate is the free ADHD test?
The ASRS-v1.1 is a validated screening tool developed with the World Health Organisation, and the six Part A questions are the most predictive of adult ADHD. It is accurate as a screener, but it is not a diagnosis: a positive screen doesn’t confirm ADHD and a negative one doesn’t rule it out. Only a full clinical assessment can give you a definitive answer.
Is there a free online ADHD test or check?
Yes. This free ADHD check uses the Adult ADHD Self-Report Scale (ASRS-v1.1) Symptom Checker, developed with the World Health Organisation. It takes a few minutes, gives an instant result, and is a useful first step — but it is a screening tool, not a diagnosis. A full assessment is needed to confirm ADHD.
Is the online ADHD self-check a diagnosis?
No. The questionnaire is based on the WHO Adult ADHD Self-Report Scale (ASRS v1.1) screener. It is a screening indicator only and cannot diagnose ADHD. A formal diagnosis requires a full clinical assessment with a specialist clinician.
How long does the ADHD check take?
About five minutes. Part A is just six questions and is the part that generates your result. Part B adds twelve optional questions for more detail on symptom severity, which you can skip if you’re short on time.
What does my score mean?
Part A counts your “shaded” answers. Four or more out of six means your symptoms are highly consistent with ADHD and further investigation is warranted. Fewer marks don’t rule ADHD out — if these traits affect your daily life, a full assessment is still worthwhile.
Can I use this check for my child?
The ASRS-v1.1 is designed for adults. If you have concerns about a child, it can still be a helpful starting point, but the right next step is a full child ADHD assessment, which we offer from age 6 with school input and a parent or guardian involved throughout.
What happens to my answers?
When you submit, your answers and contact details are sent securely to Ready Health and stored safely on file. They are used only to support your care. You can contact us at any time on 01257 676 001 with any questions.
What should I do if my result suggests ADHD?
Book a full private ADHD assessment. There is no waiting list, no referral is needed, and assessments are available online UK-wide or face-to-face in Wigan. A diagnosis is typically confirmed at the appointment, with a full written report within 48 hours.
I already have an ADHD diagnosis — can you help with medication?
Yes. If you already hold a recognised ADHD diagnosis, our private ADHD titration and medication management service can review your report and continue your treatment, online UK-wide or in person in Wigan.
