What the ASRS-v1.1 measures

Six questions from the World Health Organization's Adult ADHD Self-Report Scale, the ones found most predictive of adult ADHD symptoms. It asks about the past six months, is intended for people aged 18 or older, and takes about a minute. Your answers stay in your browser.

It is not a sum of a scale. Each of the six questions has a shaded range of answers on the printed form (from "Sometimes" upwards for the first three, from "Often" upwards for the last three), and the result is the number of answers that fall in that range, out of 6. Four or more is the published threshold. There are no severity bands, and the twelve further questions of the full checklist carry no score of their own.

ScoreBandWhat it suggests
0–3Fewer than four marksFewer than four of your answers fell in the shaded range. On these six questions the screener does not point towards adult ADHD, and a screener cannot rule anything out either; if focus, organization or restlessness are a problem for you, they are still worth raising.
4–6Four or more marksFour or more of your answers fell in the shaded range. The form's own reading: "Four (4) or more checkmarks indicate that your symptoms may be consistent with Adult ADHD. It may be beneficial for you to talk with your healthcare provider about an evaluation." A screen, not a diagnosis.

What it cannot do

A screener cannot diagnose you. It asks a fixed set of questions and scores the answers by a fixed rule; it knows nothing about your history, your circumstances, or anything you were not asked. Two people with the same score can need very different things, and someone with a low score can still be struggling in a way that deserves help. If your result worries you, or if it does not match how you actually feel, that mismatch is worth a conversation on its own.

Where this instrument comes from

Adult ADHD Self-Report Scale v1.1 Screener (ASRS-v1.1). Kessler et al. (2005), Psychological Medicine 35(2), for the World Health Organization. The 6-question Adult Self-Report Scale-Version1.1 (ASRS-V1.1) Screener is a subset of the 18-question Adult ADHD Self-Report Scale-Version1.1 (Adult ASRS-V1.1) Symptom Checklist.

We publish it here under its authors' own terms. Copyright New York University and the President and Fellows of Harvard College; the form carries the notice "COPYRIGHT © 2003 World Health Organization (WHO). Reprinted with permission of WHO. All rights reserved." NYU makes the six-question Screener freely available for clinical and non-clinical use, in electronic form included, with attribution and without modification. We have not reworded any item. A screener is validated as a specific set of words with a specific response scale, and changing them would make the scores above meaningless.

Wondering what your result actually means?
