Trouble focusing — could it be ADHD?

This is the official ASRS screening instrument, developed with the World Health Organization — the same one clinicians use for an initial assessment. It doesn’t diagnose, but it helps you see whether it’s worth looking further.

About the ASRS test

The official adult ADHD screening instrument, developed with the WHO.

What the test shows

ASRS is a short screening instrument for adults. It was developed by a research team led by Ronald Kessler together with the World Health Organization, Harvard, and New York University (Kessler et al., 2005). It’s just six questions — the ones that best predict ADHD and that clinicians use for an initial assessment.

It’s not a diagnosis, but a guide: the test shows whether it’s worth looking further and talking to a specialist.

What the test measures

  • Domain 1

    Inattention

    Trouble finishing what you start, planning things out, remembering appointments, and getting down to anything that takes mental effort.

  • Domain 2

    Hyperactivity & impulsivity

    Inner restlessness and excess energy: it’s hard to sit still, and you feel a constant pull to move and do something.

Frequently asked questions

How is this different from other ADHD tests online?

It’s the official ASRS — the very six-question screener developed with the WHO and used by clinicians. These questions weren’t chosen just to ask about symptoms — they’re the ones that pinpoint ADHD in adults most accurately.

Can this result be used as a diagnosis?

No. The ASRS is a screening tool: it shows how closely your answers resemble a picture of ADHD, but only a doctor can diagnose it after an in-person assessment. If the result worries you, it’s worth seeing a specialist or starting with a free session with an AI therapist.

How long does the test take, and do I need to sign up?

Six questions, about a minute and a half. No registration, email, or payment required — the test is free and anonymous, and you see your result right after finishing.

What should I do if the test shows pronounced signs?

Pronounced signs aren’t a diagnosis — they’re a reason to look closer. Adult ADHD is well understood, and once you see how it shows up for you, life and work get noticeably easier. It’s worth seeing a psychiatrist or therapist, and a free session with Mira can help you sort out what to do next.
