About the online adult ADHD test
The ASRS-v1.1 is the WHO-validated screening questionnaire used worldwide for adult ADHD. The Part A screener with 6 items has the strongest predictive value for clinical ADHD.
The test asks how often you have experienced each symptom over the last 6 months. You answer on a 5-point frequency scale; the result tells you whether adult ADHD is likely and what to do next.

How the ASRS score is interpreted
The ASRS counts how many of the 6 questions you answered "Often" or "Very often".
What does this test NOT measure?
The ASRS is NOT:
- ✕An autism diagnostic — try the AQ-10 if you wonder about autism
- ✕A formal diagnosis — diagnosis requires a clinical assessment
- ✕A childhood ADHD assessment — different tools are used for under-18s
- ✕A measure of severity — it screens for likelihood, not severity
ADHD is treatable
Adult ADHD is highly treatable. A combination of psychoeducation, ADHD coaching, CBT, and (where appropriate) medication can transform daily functioning. UK NHS adult ADHD services and registered private specialists offer assessment and care.

What is the ASRS adult ADHD test?
The ASRS-v1.1 (Adult ADHD Self-Report Scale) is a WHO-validated screening questionnaire developed by the World Health Organisation in collaboration with Harvard Medical School. The Part A screener asks 6 questions to identify whether adult ADHD is likely. It is widely used by clinicians, GPs, and NHS adult ADHD services.
How long does the adult ADHD test take?
The ASRS Part A takes about 3 minutes. The 6 questions ask how often you experience each symptom. You answer on a 5-point frequency scale from "Never" to "Very often", and your results are shown instantly.
Is the ADHD test free and anonymous?
Yes — the test is 100% free and anonymous. We do not ask for your name, email or any personal data to show you your results.
How is the ASRS score interpreted?
The ASRS Part A counts how many of the 6 questions you answered "Often" or "Very often". 4 or more such responses indicates that ADHD is likely and you should pursue a full assessment. 5-6 responses suggest ADHD is highly likely.
What's the difference between adult ADHD and just being scattered?
Everyone forgets things, gets distracted, or procrastinates sometimes. Adult ADHD involves a persistent pattern (since childhood, even if undiagnosed) of inattention and/or hyperactivity-impulsivity that significantly affects multiple areas of life — work, relationships, finances, daily functioning. The ASRS helps tell whether your difficulties cross that threshold.
Can the ASRS diagnose ADHD?
No — the ASRS is a screening tool, not a diagnostic instrument. An adult ADHD diagnosis requires a full clinical assessment, typically including a developmental history, current symptoms, and ruling out other conditions. Your GP can refer you to NHS adult ADHD services for assessment, or you can seek a private specialist.
How do I get an ADHD assessment in the UK?
Two main routes: (1) NHS — speak to your GP and ask for a referral to your local adult ADHD service. NHS waiting times can be long. (2) Private — book a private assessment with a registered psychiatrist or specialist clinic, faster but at a cost. The Right to Choose route is also available in England — your GP can refer you to a private provider that the NHS pays for.
What are common adult ADHD symptoms?
Inattentive symptoms include: trouble focusing, easily distracted, missing details, forgetting appointments, losing things, struggling to complete tasks. Hyperactive-impulsive symptoms include: feeling restless, talking excessively, interrupting others, struggling to wait, impulsive decisions. Many adults with ADHD have a mix of both.
Should I retake the ASRS over time?
Not really — the ASRS measures a stable trait pattern rather than a fluctuating state. Once you have done it, the next step is a clinical assessment if your score suggests ADHD is likely. You may take it again to monitor whether treatment is helping with daily functioning, but the pattern itself is unlikely to change without intervention.
