ADHD Test for Adults: What the ASRS Questions Mean

If you type "ADHD test for adults" into a search bar, the first thing you will probably meet is a short list of six questions. Sometimes it has a name at the top, sometimes it does not. Most of the time it is the WHO Adult ADHD Self-Report Scale, or a copy of it with the name stripped off.

Before my own appointment I filled in tests like this too, several of them, and I wrote about that evening in the article on whether online ADHD tests are reliable. This piece is narrower. It is about this one screener: what it asks, how it is scored, how often it gets things right, and what a score can and cannot tell you.

I am not a clinician. This is a research-based explainer built from the original validation studies and from US sources like NIMH and CHADD. I checked them on October 23, 2026.

What the ASRS is

The ASRS (Adult ADHD Self-Report Scale) was developed for the World Health Organization by Ronald Kessler and colleagues and published in 2005. The full checklist, version 1.1, has 18 questions based on the adult ADHD symptoms listed in the diagnostic manual of the time.

Out of those 18, the researchers picked the six questions that best predicted a clinician's diagnosis. Those six became Part A, the screener. The other twelve, Part B, are not scored. Clinicians use them as follow-up prompts during an interview.

When people say "the ASRS test," they almost always mean those six Part A questions. The scale is published with a World Health Organization copyright notice, and the PhenX Toolkit, a catalog of research measures maintained by RTI International, lists it as freely available for use.

The purpose is screening. In the authors' words, it is a scale for use in the general population: a quick way to flag people for whom a fuller evaluation makes sense.

The six screener questions, in plain words

I will not reproduce the questions word for word here. You can find the official form easily. What helps more is knowing what each one is trying to catch.

Question	Area it covers	What it is getting at
1	Finishing	Wrapping up the final details once the interesting or hard part of a project is done
2	Organizing	Getting things in order when a task needs planning and structure
3	Remembering	Keeping track of appointments and obligations
4	Starting	Putting off or avoiding tasks that need sustained mental effort
5	Physical restlessness	Fidgeting or squirming when you have to sit for a long time
6	Inner restlessness	Feeling overly active, as if something inside keeps pushing you

The first four are about attention and what is often called executive function: finishing, planning, remembering, starting. The last two are about hyperactivity, which in adults often shows up less as running around and more as a body and mind that will not settle.

Notice what is missing. There is nothing about emotions, sleep, time blindness or rejection sensitivity, even though many adults with ADHD say those are the hardest parts. The screener was chosen for prediction, not for completeness.

How the screener is scored

Each question asks how often something happened over the past six months, with five answers: never, rarely, sometimes, often, very often.

On the paper form some boxes are darkly shaded. For the first three questions, sometimes, often and very often fall in the shaded range. For the last three, only often and very often do. The threshold is the same on every version of the form: four or more marks in the shaded boxes means your symptoms are highly consistent with ADHD in adults and further investigation is warranted.

That wording matters. It does not say "you have ADHD." It says a closer look is justified.

Two things people often miss:

• The time frame is recent. The questions cover six months. A rough season, a new baby, a move or a burnout can push answers up.
• Sometimes and often are judgment calls. When you suspect ADHD, it is easy to round up. I did it myself on every borderline item.

How accurate is it?

This is where the numbers help, because they show both the strength and the limits.

In the 2005 validation study, the six-question screener was compared with blind clinical interviews in 154 adults from a US national survey. It correctly identified about 69 percent of the people clinicians diagnosed with ADHD and correctly ruled out 99.5 percent of those without it. Interestingly, the six questions did better than the full 18.

In 2017, a team including several of the same researchers built a new six-question screener for the DSM-5 criteria, using different questions and a points system from 0 to 24. Here is how the two compare.

	Original ASRS v1.1 screener (2005)	DSM-5 ASRS screener (2017)
Based on	DSM-IV symptoms	DSM-5 symptoms plus two executive function items
Scoring	Count of shaded answers, 4 or more of 6	Points from 0 to 24, 14 or more
Caught true ADHD cases	68.7%	91.4% (general population)
Correctly ruled out non-ADHD	99.5%	96.0% (general population)
Positives that were real ADHD	not reported in abstract	67.3% (general population), 82.8% (clinic sample)

The DSM-5 version asks about different things: concentrating when someone talks to you directly, leaving your seat when you should stay, trouble unwinding in free time, finishing other people's sentences, leaving things to the last minute, and relying on others to keep your life in order.

The last row of the table is the one I keep coming back to. Even with a well-built screener, about one in three people in the general population who screened positive did not have ADHD on closer evaluation. That is not a flaw in the test. It is what happens when you screen a large group for a condition that only some of them have.

What a screener cannot tell you

A screener measures how often you report certain problems. A diagnosis needs much more than that. According to NIMH, adults need at least five symptoms of inattention or of hyperactivity and impulsivity, and symptoms must have started before age 12. CHADD adds that symptoms must cause significant problems in at least two major areas of life, such as work and home.

The six questions check none of this directly. They cannot tell you:

• whether your symptoms were there in childhood
• whether they show up in more than one setting
• how much they actually impair your life
• whether something else explains them better
• which type of ADHD fits, if any

So a screener answers a smaller question than the one you are probably asking. It does not answer "Do I have ADHD?" It answers "Is it worth getting evaluated?"

Why you might score high without ADHD

Trouble finishing, forgetting appointments, avoiding hard tasks and feeling restless are common human experiences, and several other conditions produce them reliably.

A review by Katzman and colleagues describes how much adult ADHD overlaps with mood disorders, anxiety disorders and substance use, and how those overlapping symptoms make diagnosis harder. If anxiety is part of your picture, the article on ADHD or anxiety goes into the differences.

One small study makes this concrete. Researchers at Emory University gave the ASRS screener to adults with major depression. Most of those who screened positive did not have full ADHD on clinical assessment, while a negative screen was a fairly reliable sign that ADHD was absent. The sample was small, but the direction is clear: depression can push the score up. I wrote more about that overlap in ADHD and depression.

CHADD also mentions medical causes a clinician may want to rule out, such as thyroid problems, and recommends a medical exam if you have not had one in the past six to twelve months. Poor sleep can mimic inattention too.

Why you might score low and still have ADHD

This side gets less attention, and I think it matters more.

In the 2005 study, the original screener missed roughly three in ten adults who did have ADHD. Some people have spent years building workarounds: lists, alarms, a partner who handles the calendar, a job with heavy structure. Their answers come out as "sometimes" because the systems are doing the work.

Others have mostly inattentive symptoms and were never disruptive, which is common in inattentive ADHD and in women diagnosed late. If you have been compensating for a long time, the article on ADHD masking may sound familiar.

A low score is information, not a verdict. If your daily life is genuinely hard and has been for a long time, that is reason enough to talk to someone.

What a full adult evaluation includes

NIMH and CHADD describe the evaluation in similar terms. You can expect most of these:

• A clinical interview about current symptoms and how they affect work, relationships and daily tasks
• Rating scales, often filled in by you and by someone who knows you well
• Childhood history, sometimes with old report cards or a parent's input
• Screening for other conditions such as depression, anxiety, learning disabilities and substance use
• A medical check to rule out physical causes

The European consensus statement by Kooij and colleagues lists the same building blocks: developmental history, symptoms across settings, real impairment, and careful differential diagnosis. No online test does any of these steps.

Who can do this? CHADD lists psychiatrists, psychologists, neurologists, family doctors, nurse practitioners and clinical social workers, and suggests asking about experience with adults specifically. The practical side in the US is covered in how to get diagnosed with ADHD as an adult, and the general process is in how adult ADHD is diagnosed.

What to do with your score

Whatever your result, the most useful thing you can do is turn the score into notes.

For each question you marked often or very often, write one concrete example from the past year. Not "I'm disorganized," but "I paid a late fee three times because the bill was under a pile." This turns a short appointment into a productive one, because clinicians work with examples, not totals.

Then add what you know about your childhood. If you are unsure whether what you feel is ADHD or plain exhaustion, the article Do I have ADHD or am I lazy? may help you sort your examples.

If you do get a diagnosis and treatment comes up, medication decisions belong with your prescriber, based on your full health history.

How to spot a trustworthy online test

Not every six-question quiz online is the ASRS, and not every ASRS page is neutral. A few quick checks:

• Does it name the scale and its source? A trustworthy page says where the questions come from.
• How does it describe the result? "Consistent with ADHD, consider an evaluation" is honest. "You are 87 percent ADHD" is not something any screener can say.
• What is it selling? If the result leads straight to a paid diagnosis or a product, the test may be built to come out positive.
• What happens to your answers? Health answers are personal data. Look at what the site collects before you start.

The question a screener can actually answer

I still think these tests have value. Many people first recognize themselves in a list of questions like this. The trick is asking the test the right question.

Not "Do I have ADHD?" A screen cannot answer that. Ask instead: "Is this enough reason to see someone?" The ASRS was designed for exactly that question, and for that one, it is pretty good.
