Adult ADHD screening (ASRS v1.1) — open access

The ASRS v1.1 is the World Health Organisation Adult ADHD Self-Report Scale: 18 short questions about how often everyday ADHD traits show up for you — restlessness, difficulty finishing tasks, losing track of time, forgetfulness, acting on impulse. It is one of the most widely used adult ADHD screening questionnaires in research and clinical practice.

This is a free, open-access self-check you can complete online in about five minutes. You get your score straight away, with a clear, plain-language interpretation and the short six-item Part A that clinicians weigh most heavily. It is a first orientation, not a diagnosis — a formal ADHD assessment is always made by a qualified professional — but it can help you decide whether what you experience is worth exploring further.

Written from a neurodivergence-affirming stance: ADHD is described as a different way a mind is wired, with real support needs, not a personal failing. Many late-recognised adults also relate to autistic traits (AuDHD), so it can help to look at more than one instrument.

  • Based on the WHO ASRS v1.1 (Kessler, Adler, Ames et al., 2005)
