What the ASRS v1.1 is
The ASRS v1.1 (Adult ADHD Self-Report Scale) is the standard short screening tool for attention deficit hyperactivity disorder in adults. It was developed by the World Health Organization with researchers at Harvard Medical School and New York University, and it is in the public domain, which is why you will find it used in primary care, psychiatry, and research worldwide.
The full adult ADHD self report scale has 18 items mapped to the DSM criteria for inattention and hyperactivity impulsivity. Part A — the six questions on this page — was identified in validation work as the most predictive subset. Because those six items carry most of the screening power, Part A is routinely used on its own.
The questions are deliberately concrete. Rather than asking whether you are disorganized, the scale asks how often you have trouble wrapping up the final details of a project once the challenging parts are done, or how often you avoid or delay getting started on a task that requires a lot of thought. Those specifics are what make the scale work: adults are far better at recognizing a described situation than at rating an abstract trait.
