Adult ADHD Screening Guidance

The Adult ADHD Self-Report Scale, or ASRS, is a screening resource, not a diagnosis. Harvard's official resource page distinguishes the v1.1 six-question screener, the longer symptom checklist and ASRS-5, with separate instructions and use conditions. Official ASRS resources

This page does not administer or score an ASRS assessment. The former custom questionnaire was not the named instrument and remains withdrawn. The guide below explains the scoring distinctions, what an adult evaluation considers and how to prepare useful information without diagnosing yourself.

NIMH describes assessment using history, interviews and, where appropriate, other information or tests. Cognitive testing is not described here as compulsory for every person. NIMH adult ADHD assessment

📊 Understanding Your ASRS Score

Before interpreting any number, identify the exact instrument and scoring rule. A six-question shaded-response count and a six-question point total have different ranges. Neither should be relabeled as a universal low, moderate or high probability of diagnosis.

Harvard's February 28, 2024 scoring update describes the original 0–6 count with a positive-screen cutoff of four, and an alternative 0–24 sum with a cutoff of 14. It describes the latter as more robust for research on prevalence and correlates. The update also gives four strata for that sum. Official scoring update

These are screening cutoffs, not severity grades or individual diagnostic probabilities. NICE says diagnosis must not be based solely on rating scales or observations. A low result cannot replace an assessment of persistent difficulties, and a positive result does not decide their cause. NICE NG87, recommendation 1.3.2

If you already have a result, keep the form title, language, date, scoring method and complete responses. An entry such as “4” without the range is ambiguous: it could mean a count out of six or a sum out of 24. Recording the method prevents that simple but consequential confusion.

For a discussion, write down what prompted you to complete the form. “I keep missing appointments despite using a calendar” explains the concern better than “my score proves ADHD.” You can take the completed official form to a professional without converting it into a different scale or deciding your own presentation.

🧮 ASRS Scoring: How the Assessment Works

The two scoring methods should be applied to the exact official items, not to a replacement set of attention questions. The original method counts responses crossing the item-specific threshold; the alternative assigns a frequency value to each of the six answers and adds those values. Harvard scoring update

For the alternative sum, the published values are: never 0, rarely 1, sometimes 2, often 3, very often 4. Its four strata are 0–9 low negative, 10–13 high negative, 14–17 low positive, and 18–24 high positive. These labels do not mean mild, moderate or severe ADHD. Exact scoring instructions

Illustrative addition, not a completed screen: Six hypothetical values of 1, 2, 3, 2, 3 and 3 add to 14. Replacing the final value with 2 gives 13. The arithmetic demonstrates the stated boundary; it supplies neither responses to official questions nor a clinical conclusion about anyone.

Likewise, a hypothetical original-method tally with four threshold-crossing answers produces a count of 4/6. It is not equivalent to 14/24 simply because both cross their respective cutoff. There is no conversion formula on this page.

Use the official form's recall instructions rather than answering only for an unusually difficult day. Do not substitute questions, omit options or change a threshold to match an interpretation you prefer. Harvard specifically asks that recreated v1.1 screeners retain the instrument, response options, scoring and shading, and prefers linking to the official resources so updates remain available. Instrument use conditions

This website follows that linking approach and does not recreate the screen. Other ASRS versions have their own conditions. If another site presents an “ASRS” result, the name alone does not establish that its questions and scoring match an official version.

🧠 What ADHD Actually Looks Like in Adults

NIMH describes ADHD through persistent patterns of inattention, hyperactivity and impulsivity that interfere with functioning. Some people experience mostly one pattern, while others experience both. Many people occasionally have similar behaviors; adult assessment considers frequency, persistence, impact and more than one setting. NIMH adult ADHD overview

Examples described by NIMH include difficulty organizing or finishing tasks, losing things, forgetfulness, distraction, poor time management, interrupting and restlessness. Symptoms may change with age; inattentive symptoms can persist while visible hyperactivity or impulsivity declines. These descriptions do not establish which presentation an individual has. Adult symptoms

For your own notes, a concrete example can preserve details that a label loses. The following are illustrative observations, not additional screening items:

These examples are not evidence that ordinary mistakes equal ADHD. Their purpose is to distinguish an event from an interpretation and to make a history easier to discuss.

NIMH notes that symptoms in girls and women may have been missed during childhood, and that supportive environments or milder symptoms can delay recognition. This does not justify a blanket assertion that every woman or person with a high IQ receives a false-negative screen. Reasons for later diagnosis

You do not need to fit a childhood stereotype before discussing difficulties. At the same time, interest in a topic, occasional intense concentration or boredom is not sufficient to explain your brain chemistry. Describe what happens across tasks and settings without deciding that one behavior proves a particular mechanism.

😴 Why Do I Get Hyper When I'm Tired? The ADHD Paradox

Feeling restless when tired is an experience you can report, but this guide has not verified a universal ADHD-specific explanation for it. The earlier account that a tired brain automatically raises activity to compensate for low dopamine went beyond the evidence checked for this page. It should not be used to interpret your symptoms or medication response.

NIMH includes restlessness among adult ADHD symptoms and notes that sleep problems are common in adults with ADHD. That is a reason to discuss both experiences, not proof that tiredness causes a particular form of hyperactivity. NIMH adult symptoms and sleep context

If the pattern concerns you, separate the observations: how tired you felt, what “hyper” meant in practice, when it happened and how it affected your evening or next day. An illustrative note might say, “After a short night's sleep I talked more during the afternoon meeting, but still struggled to complete the report.” It does not need to conclude that dopamine was low or that the behavior was adaptive.

Record changes in your schedule or medicines if relevant to your own history, and ask your healthcare professional how they should be assessed. Do not start, stop or change a medicine to test an online explanation. A perceived calming effect is not used here as a diagnostic test.

For comparison over time, use the same ordinary description of the event rather than changing its meaning to fit a theory. If “hyper” means talking more on one day and feeling anxious on another, keeping those experiences separate gives a clearer account. The purpose is a useful conversation, not a self-generated biological diagnosis.

🔍 Conditions That Mimic ADHD Symptoms

An adult evaluation examines current and past medical conditions, mood and possible alternative diagnoses; ADHD can also occur with other mental health conditions. NICE's adult pathway considers whether symptoms began in childhood, persisted and are better explained by other psychiatric diagnoses, while recognizing coexisting conditions. NIMH assessment; NICE NG87, recommendation 1.2.10

For example, NIMH describes concentration difficulty and restlessness in generalized anxiety disorder, and concentration difficulty, fatigue and sleep changes in depression. These symptoms can raise overlapping concerns, but this page cannot assign their cause or exclude ADHD from a description alone. NIMH anxiety; NIMH depression

A clear timeline can keep the discussion grounded. You might separate school-age memories, earlier adult experiences and a recent change. Mark what you know directly, what someone else remembers and what is uncertain. “I remember forgetting homework, but do not know how often” is more useful than inventing a frequency to satisfy a criterion.

The following history prompts are not a differential-diagnosis test:

• When did you first notice the difficulty, and what evidence is available from that time?
• Does it occur at home, work, education or elsewhere, and what effect does it have in each setting?
• Has there been a recent change in sleep, mood, health, treatment or responsibilities that you want the evaluator to consider?
• What approaches have you tried, and what actually happened?

It is inaccurate to say that anxiety, depression or sleep difficulties always begin in adulthood while ADHD is identified in childhood. The timing and explanation need assessment, not a shortcut based on the label.

Our burnout guide explains the occupational definition and its limits; it does not screen for burnout. Our GAD-7 page provides a separate anxiety questionnaire with its own limits. Neither route determines whether your attention concerns are ADHD.

🔀 ADHD vs OCD: A Common Point of Confusion

OCD involves recurring unwanted thoughts, repetitive behaviors or both, with distress or interference in daily life. NIMH distinguishes ordinary double-checking from obsessions and compulsions. ADHD's symptom patterns and OCD's descriptions are different, but an online comparison cannot diagnose either condition. NIMH OCD overview and recognition; NIMH ADHD

The earlier explanation that ADHD distraction always comes from under-stimulation while OCD distraction always comes from anxiety was too simple. It does not establish a reliable rule for identifying the condition behind your attention difficulty.

If checking is a concern, explain what you do and what you experience before and after it. An illustrative description might be, “I return to the door repeatedly even after remembering that I locked it.” Another might be, “I check my calendar because I have previously missed appointments.” Neither observation is assigned a diagnosis here, and the fact that the actions look different is not itself a clinical test.

A conversation can include whether thoughts feel intrusive or unwanted, whether a behavior feels difficult to control and what impact it has. NIMH describes these features when explaining OCD, while emphasizing that not every habit or repeated thought is an obsession or compulsion. NIMH symptoms

Keep uncertainty in your notes rather than using a theory about the purpose of a routine to rule a condition in or out. You can say, “I am not sure why I do this, but it is affecting my day.” A healthcare professional can assess the concern and determine what further information is needed.

Do not select treatment from this comparison or from an ASRS result. NIMH describes medication and psychotherapy among adult ADHD treatments, with individual variation in what works. Those choices follow evaluation; they are not outputs of this page. NIMH treatment overview

🩺 What to Do With Your Result

If concerns persist or affect your daily life, discuss them with a healthcare professional whether a screen was positive, negative or never completed. In adult assessment, NIMH describes looking for symptoms before age 12, using past reports and information about behavior across situations. A completed form is only part of that process. NIMH diagnosis and history

Preparing an appointment: Bring the exact official form if you used one, including the date and scoring method. Add a few specific examples, when you noticed them and their consequences. If available, you can mention school reports or someone who knew you earlier; the evaluator can explain whether additional information would be helpful. Do not manufacture a childhood account or assume that missing records settles the question.

A concise example is easier to discuss than a list of internet labels. “I missed a deadline despite completing the work and this has happened in two settings” records a concern. “I have executive dysfunction because my dopamine is low” supplies an explanation this guide has not established.

Questions you might ask: What information is needed for the assessment? Which other explanations or coexisting concerns should be considered? If a diagnosis is made, what are the options, expected benefits, limitations and follow-up? If no diagnosis is made, what support is appropriate for the difficulty you reported?

You can also explain what you want to improve: keeping appointments, finishing a task, managing interruptions or another practical concern. A useful goal need not depend on choosing a diagnosis in advance.

NIMH describes treatment that can reduce symptoms and improve functioning, including medicines and psychotherapy, with a combination sometimes used. This guide does not specify a medicine, dose or schedule, and a screening category is not a treatment prescription. NIMH treatments

An assessment is not a test of character. Report difficulties and uncertainties honestly, and ask for explanations when instructions or conclusions are unclear. This page's purpose is to help you understand the sources and prepare that discussion, not to replace it.

❓ Frequently Asked Questions

What is the ASRS questionnaire?

ASRS means Adult ADHD Self-Report Scale. Harvard provides official resources for several versions, including the v1.1 six-question screener. This guide links to those resources and does not administer an assessment. Check the exact version rather than assuming every form bearing the name is interchangeable. Harvard resources

How do you score the ASRS v1.1?

The original six-question method counts threshold-crossing responses, with four or more screening positive. Harvard's alternative sums six frequency values from 0 to 4, with 14 or more screening positive. Follow the instructions for the method actually used; this website calculates neither. February 2024 scoring update

What does the ASRS score interpretation mean?

It is a screening interpretation, not an individual probability, diagnosis or ADHD severity grade. The update's four strata apply to its 0–24 method; they should not be replaced by this site's former three bands. Clinical diagnosis is not based solely on a rating scale. Scoring update; NICE diagnosis guidance

What does ASRS v1.1 Part A measure?

Part A is the six-item screener section of the v1.1 symptom checklist. Use the actual official form to see its items and response instructions. The earlier FAQ's list was not a faithful description of those items. This guide does not substitute a paraphrased set of questions. Official six-question form; Harvard resources

Is there an ICD-10 code for ADHD?

There are diagnostic coding categories, but the country and coding version matter. CDC's U.S. data brief identifies ADHD using ICD-10-CM F90; ICD-10-CM is the U.S. clinical modification, not an interchangeable label for WHO's international system. Ask the treating service which current code applies; this screen cannot assign one. CDC data brief, definitions; CDC classification and current-code browser

Is ADHD a disability?

It can qualify in some circumstances. In the United States, NIMH notes possible workplace accommodations, and EEOC explains the ADA's functional-limitation standard and supporting documentation. Qualification and a particular adjustment are individual questions; a positive screen does not establish entitlement. The cited EEOC employment explanation concerns employers with 15 or more employees. Other countries and educational settings have their own rules. NIMH; EEOC employment guidance

Can this assessment diagnose ADHD?

No. This page does not administer a screen, and an official ASRS screen alone cannot establish diagnosis. NIMH describes history, clinical interviews and other assessment information; NICE requires an appropriately qualified assessment rather than rating scales alone. Testing may be used when relevant, not as a universal compulsory step. NIMH evaluation; NICE NG87 section 1.3

I scored high but have never been diagnosed. Is that common?

Later recognition is possible. NIMH describes childhood symptoms being missed, supportive environments and demands that become harder to manage in adulthood, including missed symptoms in girls and women. That does not establish the reason for your result or justify a diagnosis. Bring your concerns and exact form to an evaluator; no unsourced prevalence or universal false-positive claim is provided here. NIMH later diagnosis
