About the test
Adult ADHD screener (ASRS)
The six-question screener from the WHO Adult ADHD Self-Report Scale (ASRS v1.1). Shows whether your answers are consistent with adult ADHD symptoms. Not a diagnosis.
- 6 questions
- About 2 min
Questionnaire / instrument: ASRS-V1.1
What does it measure?
Six common symptoms associated with adult ADHD, including difficulties with organization, completing tasks, remembering commitments and restlessness. Answers concern the past six months.
Where does it come from?
The ASRS v1.1 six-question screener is a subset of the 18-question Adult ADHD Self-Report Scale, developed by the WHO workgroup with researchers including Ronald Kessler and Lenard Adler.
How is the result calculated?
Each answer is compared with its item-specific threshold: sometimes or more for the first three questions, often or more for the last three. Four or more positive items is the published screening threshold.
What can the result tell you?
The screener is intended for adults and cannot diagnose ADHD. A positive screen can be a reason to seek a fuller assessment; sleep problems, stress and other conditions can also affect these symptoms. A low score does not rule out ADHD.
