No. This is a validated screening tool. It indicates whether ADHD is likely and whether a full assessment is warranted. Only a qualified Consultant Psychiatrist can formally diagnose ADHD after a full clinical interview.

Our quiz is based on the Adult ADHD Self-Report Scale (DSM5). It's the screening tool recommended by NICE and used widely across the NHS.

You'll see your score and what it means on the results page immediately. You'll also receive a summary by email. If your results suggest ADHD is likely, you can book a full clinical assessment with one of our Consultant Psychiatrists.

The DSM-5 is considered the global clinical standard for diagnosing mental health and neurodevelopmental conditions, including ADHD. When used by a qualified clinician as part of a full assessment, it is highly effective for identifying symptoms, patterns of behaviour, and functional impairment.

However, the DSM-5 is not a standalone test or diagnosis tool. Accuracy depends on how thoroughly the criteria are applied alongside clinical interviews, medical history, behavioural observations, and supporting evidence such as school reports or family feedback. ADHD symptoms can also overlap with anxiety, autism, trauma, sleep disorders, and other conditions, which is why comprehensive assessment is essential.

At The ADHD Centre, clinicians use DSM-5 criteria as part of a broader evidence-based diagnostic process to ensure assessments are accurate, personalised, and clinically robust.

Adult ADHD assessments at The ADHD Centre start from £695. This includes a 60–90-minute consultation, a formal diagnosis where clinically indicated, and a written report. See our full pricing page.
