What your result means
The screener counts how many of your six answers fall in its shaded range. Four or more is the level at which its authors suggest talking with a healthcare professional about an evaluation. Fewer than four does not rule ADHD out. Either way, the count is a screening result, not a diagnosis, and it does not confirm or rule out any condition.
Six questions cannot cover everything. To look at everyday task patterns, the free executive function test is an original NeuroType reflection across eight areas, from starting tasks to keeping track of time. Those patterns are common to many people and are not specific to ADHD.

How do I know if I have ADHD as an adult?
You cannot know from a questionnaire alone, and neither can anyone reading your answers. What a screener can do is show whether the patterns it asks about are frequent enough to be worth raising with a professional.
Clinicians look for a long-standing pattern rather than a bad month. They ask whether attention, restlessness or impulsivity difficulties started in childhood, show up in more than one part of life such as work and home, and get in the way of things you need to do. They also check for other explanations, including anxiety, low mood, poor sleep, thyroid problems, substance use, medication effects and stress.
A useful way to start is to write down concrete examples. Missed deadlines, lost keys and unfinished forms say more in an appointment than a general sense that something is off.
Can I test myself for ADHD?
You can screen yourself, which is what this page offers. A self-report screener such as the ASRS-6 asks how often certain experiences happen and counts the answers that land in a published range. That gives you a reason to look further, or not.
Screening yourself is not the same as being assessed. An assessment adds a developmental history, often input from someone who knew you as a child, a look at how the difficulties affect daily life, and a check for other causes. No self test does those things, however long it is.
If you want more detail than six questions can give, the ADHD traits test is an original NeuroType reflection across eight everyday areas. It is not a clinical instrument either, but it can help you sort examples before an appointment.
What happens in an adult ADHD assessment?
Most adult assessments follow a similar shape wherever you live. A clinician takes a detailed history of your childhood, school, work, relationships and health. You usually complete one or more rating scales, and you may be asked for a second view from a partner, parent or old school reports. The clinician then compares what they have heard against the diagnostic criteria in DSM-5-TR or ICD-11.
Some services add computer-based attention tasks. These can add information, but no attention task, blood test or brain scan can establish ADHD on its own. An appointment typically runs from one to three hours, sometimes split over more than one session.
Who can diagnose ADHD in adults?
It depends on the country, and sometimes on the state or province. In the US, psychiatrists, psychologists, psychiatric nurse practitioners and some primary care clinicians assess adults. In the UK and Ireland, public assessment usually starts with a GP referral to a specialist adult ADHD or mental health team. In Canada, family doctors, psychiatrists and psychologists can assess, though psychologists cannot prescribe.
Australia and New Zealand have been widening who can diagnose. In New Zealand, from 1 February 2026, GPs and nurse practitioners can start ADHD treatment for adults. In Australia, Queensland GPs with specialist registration have been able to diagnose and treat adults since 1 December 2025, and other states are rolling out GP training on their own timetables.
Can ADHD be diagnosed online?
An assessment can be carried out by video with a qualified clinician, and many services in every English-speaking country now work this way. That is different from an online quiz, which can only screen.
If you are choosing a telehealth service, check who is responsible for the diagnostic decision and how they are registered, how long the assessment takes, whether they ask about childhood and other explanations, and what follow-up they offer. Be cautious of any service that promises a result in minutes or ties the outcome to buying medication. In the US, the temporary federal rules that let clinicians prescribe controlled medicines by telehealth without an in-person visit were extended to 31 December 2026, so check the current position before relying on them.
How much does an ADHD assessment cost?
Free online screeners like this one cost nothing. A full assessment is a different matter, and the price depends mostly on the health system you are in.
In the UK, Ireland, Canada, Australia and New Zealand, a publicly funded route exists but waits are often long, sometimes years. Private assessments in those countries are paid out of pocket, sometimes with partial help from private insurance or workplace benefits. In England, Right to Choose can let you ask your GP to refer you to another NHS-contracted provider, which some people use to shorten the wait. In the US, cost depends on your insurance plan, whether the clinician is in network, and whether psychological testing is included, so ask your insurer and the clinic for a written estimate before booking.
Is ADHD different in women?
The diagnostic criteria are the same for everyone, but research reviews describe girls and women being identified later on average. Reasons discussed include referral patterns that favour disruptive behaviour, more inattentive than hyperactive presentations, and anxiety or low mood being noticed first.
The ASRS-6 asks the same six questions of everyone. If you are a woman wondering whether ADHD was missed, the screener is still a reasonable first step, and the article on ADHD tests for women covers what to bring to an appointment.
Could it be anxiety rather than ADHD?
It could be either, both, or something else. Anxiety can make concentration hard, and ADHD difficulties can leave people anxious about what they have forgotten. Poor sleep, low mood, menopause, thyroid problems and some medicines can also affect attention.
This is one of the main reasons a screener cannot settle the question. A clinician asks when the difficulties began, whether they come and go with worry, and how they show up across your life.
Frequently asked questions
What is the ASRS-6?
The Adult ADHD Self-Report Scale v1.1 Screener is a six-question screener for adults aged 18 and over, created by Dr. Lenard Adler of NYU and Dr. Ronald Kessler of Harvard. It is one of the most widely used adult ADHD screening questionnaires. Four of the questions cover attention and organisation, and two cover restlessness.
How is it scored?
Each question has a darkly shaded range on the published form. For questions 1 to 3 that is Sometimes, Often or Very Often. For questions 4 to 6 it is Often or Very Often. The screener counts how many answers land in the shaded range. Four or more is the published threshold for suggesting a conversation with a healthcare professional.
Is this an ADHD diagnosis?
No. A screener is a starting point, not a diagnosis. Its authors state that diagnosis should never be made solely from a screener score. Formal assessment requires a qualified professional who can look at your history, how long the difficulties have lasted, how they affect daily life, and other explanations such as anxiety, low mood, sleep or stress.
How accurate are online ADHD tests?
The ASRS-6 was designed to pick out adults who are more likely to meet criteria, so it is good at flagging that a conversation is worth having. It can also flag people who turn out not to have ADHD, and it can miss people who do. Treat the count as a reason to look further, not as an answer.
Where do my answers go?

How do I get assessed for ADHD as an adult?
In the US, adult ADHD can be assessed by a psychiatrist, psychologist, or a primary care clinician, and many people start with their primary care provider or a telehealth service. Check what your insurance covers before booking. In the UK and Ireland the usual route starts with your GP, in Canada with your family doctor, and in Australia and New Zealand with a GP, where some GPs can now assess adults themselves. Public waiting times can be long everywhere. Bringing concrete examples from work, home and relationships makes any assessment more useful.
