ASRS-v1.1 · World Health Organization
Adult ADHD Self-Screening Test
A 5-minute self-screening based on the Adult ADHD Self-Report Scale (ASRS-v1.1), the standard 18-item instrument used in clinical research and primary care. Answer how often each statement has applied to you over the past 6 months.
This is not a medical diagnosis. Only a qualified clinician (psychiatrist, psychologist, or licensed mental-health professional) can diagnose ADHD. This screening is for educational and self-reflection purposes only. If your results concern you, please share them with a healthcare provider.

Important: A high screening score does not mean you have ADHD, and a low score does not rule it out. Symptoms can overlap with anxiety, depression, sleep deprivation, and stress. The most reliable next step is a structured evaluation by a clinician.
