Frequently asked questions
Is this ADHD test free?
Yes — completely free, with no sign-up, no email required and no hidden paywall. Your answers never leave your device.
How accurate is the ASRS v1.1 self-test?
The ASRS v1.1 was developed by the World Health Organization and is one of the most widely used adult ADHD screening tools in clinical practice. It is a screening instrument, not a diagnosis: a positive result means a professional evaluation is worthwhile, not that you definitely have ADHD.
How long does the test take?
About 5 minutes. There are 18 questions about the last 6 months of your life, each answered on a simple frequency scale.
Can this test diagnose ADHD?
No online test can diagnose ADHD. Only a qualified professional — a psychiatrist or clinical psychologist — can make a diagnosis after a full evaluation. This screener helps you decide whether that conversation is worth having, and gives you a result you can bring to the appointment.
Is the test suitable for teenagers or children?
The ASRS v1.1 is designed and validated for adults (18+). Children and teenagers should be assessed by a paediatrician or child psychiatrist using age-appropriate tools.
What should I do if I score positive?
Print or screenshot your result and consult a qualified professional. In Sri Lanka you can channel a psychiatrist privately or visit a government hospital mental health clinic for free. Wherever you are, the tools on this site can help in the meantime.
