How many questions are on the ASRS?

Short answer

The ASRS v1.1 screener has six questions, each with five answer choices from Never to Very Often, about the past six months. Those six questions are also Part A of the longer 18-question ASRS v1.1 Symptom Checklist, whose other twelve questions form Part B. ADHDFalcon uses the official six-question screener, followed by an optional, separate reflection section of our own.

The answer depends on which ASRS you mean, because the name covers a short screener and a longer checklist from the same authors. Here is how they fit together.

The six-question screener

Each of the six questions asks how often something has happened in the past six months, with five answer choices: Never, Rarely, Sometimes, Often, and Very Often. Four or more answers in the shaded boxes make a positive screen.

The 18-question Symptom Checklist

ASRS versions at a glance
Version	Questions	Main use
ASRS v1.1 Screener	Six	Quick screening for adults
ASRS v1.1 Symptom Checklist	Eighteen (Part A plus Part B)	Fuller symptom checklist
ASRS DSM-5 version	Six in the screener, twelve more in Part B	Updated to DSM-5 criteria

Our pages on six versus eighteen questions and on the ASRS-5 go into the differences in more depth.

Why only six questions?

A short screener is quick to complete and easy to score, which makes it practical as a first step. The trade-off is that six questions cannot cover the full range of ADHD symptoms, childhood history, or other explanations. That is the work of a full evaluation.

What our screener includes

Part 1 is the official six-question ASRS v1.1 Screener, presented electronically without changes. Your result is always free.

Part 2 is optional and separate: the ADHDFalcon Attention Profile, an original, non-clinical set of 24 self-reflection statements across six everyday areas (Focus, Organization, Time, Getting started, Restlessness, Pacing). It is purely descriptive, without norms, and it does not measure ADHD. It never changes your ASRS result.

If a site shows a different number of questions

You may come across online quizzes that call themselves the ASRS but have a different number of questions or different wording. Some may be the full checklist, some may be other instruments, and some may be altered versions. The six-question screener is meant to be used as written, so if the count or the wording looks different, check whether the site credits New York University and Harvard and explains which version it uses.

How long it takes

Find a quiet moment, think about a clear six-month window, and answer for how things usually went rather than your best or worst week.

Most people finish the six screener questions in a few minutes. The optional reflection section takes a little longer. There is no time limit, and it is better to answer thoughtfully than quickly.

Frequently asked questions

Is the ASRS 6 or 18 questions?

Both exist. The ASRS v1.1 Screener has six questions. The ASRS v1.1 Symptom Checklist has eighteen, and its Part A is the same six questions as the screener.

Which ASRS does ADHDFalcon use?

The official six-question ASRS v1.1 Screener, presented electronically without changes, followed by an optional, separate self-reflection section that is not part of the ASRS.

Is a six-question screener enough to know if I have ADHD?

No. A screener can suggest whether a fuller evaluation is worth considering. Only a qualified clinician can make a diagnosis after a thorough evaluation.
