ASRS Adult ADHD Screener

WHO Adult ADHD Self-Report Scale (ASRS v1.1) — 6-question screener for adults 18+

Medical disclaimer This screener is for educational purposes only. It is not a diagnosis and does not replace evaluation by a qualified healthcare professional (psychiatrist, psychologist, or other licensed clinician).

Over the past 6 months, how often have you experienced the following? Choose the option that best describes you. Questions are from the official ASRS v1.1 screener (WHO / Harvard Medical School).

1. How often do you have trouble wrapping up the final details of a project, once the challenging parts have been done?
2. How often do you have difficulty getting things in order when you have to do a task that requires organization?
3. How often do you have problems remembering appointments or obligations?
4. When you have a task that requires a lot of thought, how often do you avoid or delay getting started?
5. How often do you fidget or squirm with your hands or feet when you have to sit down for a long time?
6. How often do you feel overly active and compelled to do things, like you were driven by a motor?

Your screening results

What to do next: Share these results with a healthcare provider if you want a formal evaluation. A diagnosis typically includes clinical interview, history, and sometimes input from someone who knows you well.
