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).

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.
