The six-question ADHD adult self report scale developed by the World Health Organization. Answer each question based on how you have felt over the past six months. It takes about two minutes, and your ASRS v1.1 score appears immediately.
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.
The ASRS is not scored by adding up points, which surprises most people. Each of the six questions has a shaded threshold, and what gets counted is how many of your answers fall at or above it.
The two different thresholds are not an oversight. Occasional disorganization is close to universal, so the inattention items need a lower bar to be informative. Feeling compelled to move as though driven by a motor is not universal, so those items only count when the answer is emphatic.
What a positive screen does not mean: it does not mean you have ADHD. It means a clinical conversation is justified. Attention deficit hyperactivity disorder shares its surface features with several other conditions, and the screener cannot tell them apart.
A diagnosis of ADHD requires three things the ASRS never asks about: onset before age 12, impairment in two or more settings, and the exclusion of other explanations. An elevated score is common in adults who turn out to have something else entirely, or something else as well.
Finding one of these does not rule out ADHD. Adults commonly have both, and the order in which things are treated matters. Sorting it out is the point of an adult ADHD evaluation.
The results screen includes a print option. Printing to PDF gives you a copy to bring to a first appointment, which genuinely shortens the visit, it means the clinician can spend the time on developmental history rather than on questions you have already answered. Nothing you enter is transmitted to us or stored on a server; the screener runs entirely in your browser.
New-patient appointments at MindHealth are typically available within about a day, by telehealth anywhere in Oregon and Washington.
Part A is scored by counting shaded-box responses, not by adding points. Four or more marks out of six is a positive screen, your symptoms are highly consistent with adult ADHD and a full evaluation is warranted.

Part A is the most predictive subset of the full 18-item scale and performs well as a screening tool. It is not diagnostic, it cannot establish childhood onset, functional impairment, or rule out the conditions that mimic attention deficit hyperactivity disorder.
No. Diagnosis requires a clinical evaluation covering developmental history before age 12, impairment in two or more settings, and a differential considering anxiety, depression, sleep disorders, thyroid disease, and substance use.
The full scale has 18 items. Part A is the first six, identified in validation research as the most predictive of adult ADHD, and is used alone as a short screener. Part B adds twelve items that give additional clinical detail but do not change the screening result.
Yes. Free, no account, and it runs entirely in your browser, your answers are never sent to us or stored anywhere. The ASRS itself is in the public domain.
