ASRS v1.1 Adult ADHD Self-Report Scale

The ASRS v1.1 is the adult ADHD self-report scale developed with the World Health Organization. Its first six questions, Part A, screen adults for ADHD: four or more answers in the shaded boxes is a positive screen.

Who holds it

New York University and the President and Fellows of Harvard College. Developed with the World Health Organization by Drs. Ronald C. Kessler, Lenard Adler, and colleagues.

How you may use it

The six-question screener is free to use without formal permission: cite the 2005 paper, keep the copyright notice, and don’t change its answers, scoring, or shading. The full 18-question checklist and the ASRS-5 need permission through NYU’s licensing site.

Use it for

  • Primary care screening
  • Psychiatry intake
  • Student health
  • Adult ADHD referrals
  • Telehealth visits

What the score means. 0 to 6, Part A answers in the shaded range.

0 to 3: Screen negative

Fewer than four Part A answers in the shaded range. Adult ADHD is less likely, but go ahead with an assessment if the history strongly suggests it.

4 to 6: Screen positive

Current symptoms are highly consistent with adult ADHD. Follow up with a full assessment: childhood onset, several settings, impairment, and other causes.
  • Count the Part A answers that fall in the shaded boxes on the official form. The shading starts at a different answer for some items, so count from the form, not from one cut point.
  • Four or more of six is a positive screen. This is the rule built into the official screener and the one most clinics use.
  • Part B’s 12 items are not scored for the screen. They show which symptoms are present and guide the interview.
  • Harvard’s 2024 scoring update describes a second method: score each Part A answer 0 to 4, from never to very often, and add them for a total of 0 to 24, with 14 or more positive. Totals of 0 to 9 are low negative, 10 to 13 high negative, 14 to 17 low positive, and 18 to 24 high positive. It was found more robust for research and prevalence studies. Record which method you used.
  • The ASRS-5 is a separate six-question screener written for DSM-5 in 2017. Its items carry different weights, its total runs from 0 to 24, and 14 or more is the usual positive cutoff. Don’t score ASRS v1.1 answers with ASRS-5 rules, or the other way round.
  • A positive screen is not a diagnosis. Diagnosis needs a clinical interview showing symptoms before age 12, in two or more settings, with impairment, and not better explained by another condition.

How to give it, score it, and read it.

Giving it

Adults 18 and over answer on the official form, on paper or online, about the past six months. Part A takes about two minutes.

  • Use the official form, so the answers and shading are exactly as published
  • Let the patient answer alone where possible; read the items word for word if reading is hard
  • Use a published translation where one exists; Harvard posts the screener in about 20 languages

Avoid: Asking the questions from memory or in your own words. The screen was validated on the published wording.

Scoring Part A

Count how many of the six answers fall in the shaded boxes. Four or more is a positive screen.

  • Count from the form: the shading begins at a different answer for some items
  • Record the count and which items were shaded
  • If your service uses the 0 to 24 sum, record that too, and say which method you used

Avoid: Adding the answers up as points and then applying the 4 of 6 cutoff to the total. The two methods use different numbers.

Part B

Part B’s 12 items aren’t scored for the screen. They show which symptoms are present and where to probe.

  • Note how many Part B answers fall in the shaded boxes, and which symptom areas they cover
  • Use them to plan the interview: inattention, hyperactivity, and impulsivity
  • Ask for an example of each shaded answer at work, at home, and in relationships

Avoid: Adding Part B to Part A for a bigger total. Only Part A decides the screen.

After a positive screen

A positive screen means current symptoms are highly consistent with adult ADHD. A full assessment decides whether it is ADHD.

  • Take a childhood history: several symptoms before age 12, from school reports or a parent’s account where possible
  • Check for symptoms in two or more settings, and for real impairment
  • Look for other causes: depression, anxiety, bipolar disorder, poor sleep or sleep apnea, substance use, thyroid disease, and medicines

Avoid: Starting a stimulant on the screen result.

After a negative screen

Fewer than four shaded answers makes adult ADHD less likely, but the screener misses about one in three adults who have it.

  • Go ahead with an assessment when the history strongly suggests ADHD
  • Ask whether the patient answered for a good stretch, or played symptoms down
  • Record the result, so a later screen can be compared

Two recorded results. Every part, filled in.

Each one follows the recording template. Use them to judge how much to write.

ASRS result: positive screen, referred for a full adult ADHD assessment

University student health clinic, first visit about falling behind, completed on paper before the appointment

Part A screen

Answers in the shaded range: 5 of 6, items 1 to 4 and 6. Screen positive. Sum score not used.

Part B

8 of 12 answers in the shaded range, mostly inattention, with some restlessness and few impulsive answers. Her examples: lab keys and notebooks lost most weeks, experiments finished but write-ups left for weeks, and leaving seminars to walk the hallway.

Collateral and context

27-year-old graduate student in the third year of a chemistry PhD. Two thesis chapter deadlines missed this year, raised in writing by her supervisor. Her mother, by phone with consent, recalls teachers from grade 3 calling her “a daydreamer” who rarely finished homework; she has kept the report cards. PHQ-9 6. GAD-7 7. Sleeps about 7 hours. Alcohol 3 drinks a week, cannabis rarely, 4 coffees a day. No spells of high mood or little need for sleep. No head injury.

Next step

Positive screen with a childhood history worth exploring. Referred for a full adult ADHD assessment with the campus psychiatry service; she will bring her report cards. No medication started from the screen. In the meantime, a weekly written plan with her supervisor and shorter interim deadlines. Follow-up in 4 weeks.

Common mistakes, and how to avoid them.

Diagnosing from the screen

A positive Part A shows current symptoms. It doesn’t show they began in childhood, or that depression, anxiety, or poor sleep isn’t causing them.

Counting with one cut point

The shaded boxes don’t start at the same answer on every item. Count them on the official form.

Scoring Part B into the screen

Part B adds detail about which symptoms are present. Only Part A decides whether the screen is positive.

Mixing up scoring methods

The 4 of 6 count, the 0 to 24 sum, and the ASRS-5 each have their own cutoff. Record which one you used.

Ignoring what else is going on

Depression, anxiety, and poor sleep all push answers into the shaded range. Record them next to the result, and repeat the screen once they’re treated.

Talk through the screen. Review the note.

Frequently asked questions.

How do you score the ASRS?

Count how many of the six Part A answers fall in the shaded boxes on the official form. Four or more is a positive screen; 0 to 3 is negative. The shading starts at a different answer for some items, so count from the form. Part B isn’t scored for the screen.

What does a positive ASRS screen mean?

It means current symptoms are highly consistent with adult ADHD, and a full assessment should follow. It isn’t a diagnosis. That needs a clinical interview showing symptoms before age 12, in two or more settings, with impairment, and not better explained by something else, such as depression or poor sleep.

What is the 0 to 24 ASRS score?

A second way to score Part A, described in Harvard’s 2024 scoring update. Each answer scores 0 to 4, from never to very often, for a total of 0 to 24, and 14 or more is positive. Totals of 0 to 9 are low negative, 10 to 13 high negative, 14 to 17 low positive, and 18 to 24 high positive. It was found more robust for research; many clinics still use the 4 of 6 count.

What is the difference between the ASRS v1.1 and the ASRS-5?

The ASRS v1.1 was written for DSM-IV and is the version most clinics use. The ASRS-5, published in 2017, is a separate six-question screener written for DSM-5. Its items carry different weights, its total runs from 0 to 24, and 14 or more is the usual positive cutoff. It needs permission to use, through NYU’s licensing site.

How accurate is the ASRS screener?

In the 2005 validation study, Part A classified 98% of adults correctly: it picked up 69% of those with ADHD and correctly screened out 99.5% of those without it. So a negative screen can miss ADHD. In clinics, results vary more, partly because depression, anxiety, and poor sleep also raise the count.

Who can give the ASRS?

Anyone in the care team can hand it out, and patients fill it in themselves: in the waiting room, online, or before a visit. A clinician reads the result, and the diagnosis comes from a full assessment by a clinician trained to diagnose ADHD, such as a psychiatrist, psychologist, or physician.

Is the ASRS free?

The six-question screener is free to use and needs no formal permission: cite the 2005 paper, keep the copyright notice, and don’t alter the form. Download it, with its translations, from Harvard’s National Comorbidity Survey site. The full 18-question checklist and the ASRS-5 need permission through NYU’s licensing site.
