ASRS (Adult ADHD Self-Report Scale): questions, scoring and accuracy
The ASRS is a short questionnaire developed with the World Health Organization to screen adults for ADHD. Its six-question screener is a common first check. Here is what it asks, how it is scored and how far you can trust the result.

In short
- The Adult ADHD Self-Report Scale (ASRS v1.1) was developed with the World Health Organization and published in 2005. The full version has 18 questions; the screener is the six that best predicted a diagnosis.
- Each answer has a shaded range. For questions 1 to 3 it starts at “Sometimes”, for questions 4 to 6 at “Often”. Four or more answers in the shaded range is a positive screen.
- In the study that developed it, the screener picked up 68.7% of adults with ADHD and correctly cleared 99.5% of those without it.
- A positive screen means a full assessment is worth doing. It is not a diagnosis, and a negative screen does not rule ADHD out.

What the ASRS is
The Adult ADHD Self-Report Scale was developed by researchers working with the World Health Organization and published in 2005. The copyright is held by New York University and Harvard. It was designed as a short scale that could be used in the general population as well as in clinics.
There are two versions of version 1.1:
- The Symptom Checklist has 18 questions, one for each ADHD symptom in the diagnostic manual of the time (DSM-IV). It is split into Part A (six questions) and Part B (twelve).
- The Screener is Part A on its own. The developers found these six questions were the most predictive of symptoms consistent with ADHD, so they are used as the short screening test.
A newer version, the ASRS-5, was published in 2017 to match the current diagnostic manual (DSM-5). Unlike the six-question v1.1 screener, which is free to use, the ASRS-5 and the full 18-question checklist need permission from the copyright holders.
The six screener questions
Each question asks how often something has happened over the past six months, with five answers: Never, Rarely, Sometimes, Often and Very Often. On the official form, some answer boxes are shaded. Those are the ones that count.
| Question | Counts if you answer |
|---|---|
| 1. How often do you have trouble wrapping up the final details of a project, once the challenging parts have been done? | Sometimes, Often or Very Often |
| 2. How often do you have difficulty getting things in order when you have to do a task that requires organization? | Sometimes, Often or Very Often |
| 3. How often do you have problems remembering appointments or obligations? | Sometimes, Often or Very Often |
| 4. When you have a task that requires a lot of thought, how often do you avoid or delay getting started? | Often or Very Often |
| 5. How often do you fidget or squirm with your hands or feet when you have to sit down for a long time? | Often or Very Often |
| 6. How often do you feel overly active and compelled to do things, like you were driven by a motor? | Often or Very Often |

Questions 1 to 4 are about inattention and organisation. Questions 5 and 6 are about restlessness and hyperactivity. Note that the bar is lower for the first three questions: they count from “Sometimes”.
How the ASRS is scored
Scoring the screener is a count, not a total:
- For each question, check whether your answer falls in the shaded range: “Sometimes” or above for questions 1 to 3, “Often” or above for questions 4 to 6.
- Count how many of the six answers are in the shaded range.
- Four or more means your symptoms may be consistent with adult ADHD and further assessment is warranted. Three or fewer is a negative screen.
Because it is a count, answering “Very Often” scores no more than “Often”. A score of 6 does not mean more severe ADHD than a score of 4. It just means more of the six questions landed in the shaded range.
If you take the full 18-question checklist, only Part A is scored against the cut-off. Part B has no cut-off; clinicians use it to talk through the rest of the symptoms with you.
How accurate the ASRS is
The 2005 study that developed the ASRS checked it against clinical interviews. The six-question screener did better than the full 18 questions:
| Measure | 6-question screener | 18-question version |
|---|---|---|
| Sensitivity (people with ADHD it picked up) | 68.7% | 56.3% |
| Specificity (people without ADHD it correctly cleared) | 99.5% | 98.3% |
| Overall accuracy | 97.9% | 96.2% |
A 2007 study of 668 members of a large US health plan found the screener agreed strongly with clinician diagnoses, with an area under the curve of 0.90 (1.0 would be perfect, 0.5 no better than chance).
Three things to keep in mind:
- It misses people. A sensitivity of 68.7% means about three in ten adults who had ADHD screened negative.
- The high overall accuracy partly reflects the setting. Most people in a general population sample do not have ADHD, and a test that rarely says “yes” will be right about most of them.
- Other conditions can push scores up. Depression, anxiety and poor sleep all affect attention and organisation, so they can produce the same answers.
What your result means
Four or more (a positive screen). The pattern ADHD describes shows up in how you answered, and a full assessment is a reasonable next step. It is not a diagnosis. An assessment has to establish that the difficulties go back to childhood, show up in more than one part of your life, and are not better explained by something else.
Three or fewer (a negative screen). ADHD is less likely, but it is not ruled out. People who have built strong coping systems, people whose difficulties are mostly inattentive, and women who were never flagged as children can all score low. The screener also only asks about the last six months. If something is affecting your work, study or relationships, it is still worth raising with a GP or psychologist.
Where the ASRS fits in an ADHD assessment
A questionnaire is where an ADHD assessment starts, not where it ends. Healthdirect summarises the criteria a diagnosis has to meet: symptoms lasting more than six months, present before age 12, causing real problems in at least two settings, and interfering with daily life. Australia’s ADHD guideline says the assessment should draw on information about more than one setting and from more than one person.
So a formal assessment usually adds a clinical interview against the diagnostic criteria, a developmental history (ideally with someone who knew you as a child), longer rating scales, and checks for the conditions that look like ADHD. In Australia, ADHD can be diagnosed by a psychologist, psychiatrist or paediatrician; who can prescribe medication depends on your state.
Questions people ask
What does ASRS stand for?
Adult ADHD Self-Report Scale. Version 1.1 was developed with the World Health Organization and published in 2005. You may also see it called the WHO ASRS.
Can the ASRS diagnose ADHD?
No. It is a screening questionnaire. A positive result means a full assessment is worth doing; a diagnosis needs a clinical interview, a developmental history and a clinician ruling out other explanations.
What is a positive ASRS score?
On the six-question screener, four or more answers in the shaded range is a positive screen. The shaded range is “Sometimes” or more often for questions 1 to 3, and “Often” or more often for questions 4 to 6.
How accurate is the ASRS?
In the 2005 study that developed it, the six-question screener picked up 68.7% of adults with ADHD and correctly cleared 99.5% of those without it. It misses about three in ten people with ADHD, so a negative screen does not rule it out.
What is the difference between the ASRS v1.1 and the ASRS-5?
The ASRS v1.1 (2005) is based on the older DSM-IV criteria. The ASRS-5 was published in 2017 to match DSM-5. The six-question v1.1 screener is free to use; the ASRS-5 needs permission from the copyright holders.
