Adult ADHD Self-Report Scale (ASRS)
One in twenty Australians have ADHD, however it often goes undiagnosed. To facilitate early detection, the World Health Organization (WHO), NYU, and Harvard developed the Adult ADHD Self-Report Scale (ASRS). ASRS is a quick and effective screening test for ADHD. The most up to date variant is the DSM-5 Adult ADHD Self-Report Screener (ASRS-5).

- Questions: 6 questions
- Sensitivity: 91.4%
- Specificity: 96.0%
The ASRS test is a tool to help you screen for ADHD symptoms, but it isn't a diagnosis. If your results point towards ADHD, it's essential to speak with your GP or a psychiatrist for an official diagnosis. They are your best resource for understanding and managing ADHD.
There are two common versions of the ASRS Test: ASRS v1.1 and ASRS-5. ASRS v1.1 was originally released in 2005 calibrated to DSM-IV criteria. ASRS-5 is an updated version calibrated to the improved DSM-V criteria. ASRS-5 is preferred as it is more accurate than ASRS v1.1.
Validity
Although the ASRS-5 screener can effectively diagnose ADHD in adults, it cannot rule out other medical conditions that may impact the diagnosis of ADHD. The sensitivity and specificity of the ASRS-5 is as follows (source):
- Sensitivity (true positive rate) = 91.4%
- Specificity (true negative rate) = 96.0%
To simplify, this means that 91.4% of people who have a positively screened for ADHD are confirmed to have ADHD and 96% of people who are negatively screened for ADHD are confirmed to not have ADHD.

Frequently Asked Questions
While the ASRS test effectively identifies ADHD symptoms, only a qualified healthcare professional can diagnose ADHD. The ASRS is a screening tool, not a diagnostic instrument.
Studies show a sensitivity rate of 91.4% and a specificity rate of 96.0% for the 6-question ASRS test (source), highlighting its reliability. That being said, a comprehensive evaluation by a healthcare professional is irreplaceable.
A score suggesting ADHD should prompt you to seek a comprehensive assessment from a healthcare professional. In Australia, visit your GP, who may refer you to a specialist or consider Kantoko for affordable ADHD diagnosis and treatment.
How Scoring Works
The ASRS-5 uses a simple point system for each question, where your frequency of experiencing each symptom determines the score:
- Never = 0 points
- Rarely = 1 point
- Sometimes = 2 points
- Often = 3 points
- Very Often = 4 points
Your total score is calculated by adding up the points from all six questions, with a maximum possible score of 24 points. Research has established that:
- A score of 14 or higher suggests you may have ADHD symptoms that warrant further evaluation
- A score of less than 14 suggests ADHD is less likely, but doesn't rule it out completely
Remember that this screening tool is just one step in the assessment process. Your healthcare provider will consider these results alongside other factors when making a diagnosis.
