Trouble focusing, impulsivity, restlessness.
Check your adult ADHD traits with the official WHO ASRS screener.
The ASRS (Adult ADHD Self-Report Scale) v1.1 is an adult ADHD self-report scale published in 2005 by the World Health Organization (WHO) together with Kessler and colleagues. Of its 18 items, the 6 found to best identify adult ADHD are grouped as a screener, and this test uses those 6 items. They cover trouble finishing tasks, difficulty getting organized, forgetting appointments or obligations, putting off tasks that need focus, fidgeting, and feeling driven to stay constantly busy.
ADHD traits matter when they show up consistently over a long time, not for a day or two, so the test asks about the past six months. Keep in mind that anyone can show similar patterns during a busy or stressful period.
This result is not an ADHD diagnosis; it is a screening reference to see whether a professional evaluation may be worthwhile. An actual diagnosis is made by a psychiatrist who looks at patterns since childhood, difficulties across several areas of life, and other possible causes such as depression, anxiety or sleep problems. If the result concerns you or daily life is hard, consider seeing a specialist.
