Test ADHD
This assessment uses the Adult ADHD Self-Report Scale (ASRS v1.1), developed by the World Health Organization and researchers at Harvard Medical School. It is the same screening instrument used in clinical settings. Answer based on how you have felt and behaved over the past six months.
A quick, honest self check
You will answer 18 questions on a five point frequency scale, from Never to Very Often. There is no need to overthink any single question. Go with your first instinct.
This is a screening tool, not a diagnostic exam. A result here can be a useful, evidence-based starting point for a conversation with a clinician, not a replacement for one.

About The ASRS v1.1
The Adult ADHD Self-Report Scale was developed in collaboration with the World Health Organization and a team of ADHD researchers, including Ronald C. Kessler at Harvard Medical School, and is grounded directly in DSM-IV diagnostic criteria for ADHD. It is one of the most widely used and studied adult ADHD screening tools, adopted in both clinical practice and large scale epidemiological research.
Part A: the core screener
The first six questions make up Part A, the validated screening portion. In clinical use, a specific pattern of answers across these six questions is considered highly predictive of an adult ADHD diagnosis. This is the part of the test that matters most for your result.
Part B: additional symptom detail
The remaining twelve questions add further clinical detail about how symptoms show up in daily life. They contribute to your overall symptom score but are not part of the core validated screen itself.
How to answer
Base every answer on the last six months, not just today or this week. ADHD symptom patterns are about consistency over time, not a single hard day.
Frequently asked questions
Yes, in the sense that the ASRS v1.1 is a real, validated screening instrument used in clinical and research settings. What a doctor adds on top is a structured interview, developmental history, and clinical judgment, which a self-scored online version cannot replace.
It means your answer pattern on the six core screening questions matches the pattern that research has linked to a higher likelihood of adult ADHD. It is a strong signal worth discussing with a professional, not a diagnosis on its own.
It is possible, though less common. Symptoms can be underreported, masked by coping strategies, or affected by mood and context on a given day. If you still have concerns despite a negative screen, that concern itself is worth raising with a clinician.
Bring it to a primary care doctor, psychiatrist, or psychologist. Mention that you completed the ASRS v1.1 and share your Part A result. They can guide you through a full evaluation from there.
