Inattentive ADHD test for adults: what a free screener can show

Current diagnostic criteria describe three presentations of ADHD: predominantly inattentive, predominantly hyperactive-impulsive, and combined. The inattentive presentation applies when someone meets the inattention criteria without enough current hyperactive-impulsive symptoms for the combined presentation. It is not a different condition, and the presentation can change over a person's life.

In adults, inattentive difficulties often show up as losing the thread while reading or in meetings, careless mistakes on detailed work, trouble organising multi-step tasks, avoiding tasks that need sustained mental effort, losing things, being easily pulled off track, and forgetting appointments or bills. Plenty of adults without ADHD recognise some of these. What clinicians look for is a long-standing pattern that started in childhood, shows up in more than one setting, and causes real problems.

The ASRS v1.1 Screener was developed with the World Health Organization by Kessler, Adler and colleagues. Of its six questions, four ask how often you have difficulty with attention and organisation in everyday tasks, such as finishing the final details of a project, getting things in order, and remembering appointments. Two ask about restlessness.

Each question has a shaded range on the published form, and the screener counts how many answers land in it. Four or more is the published level at which a conversation with a healthcare professional is suggested. Because most of the questions are about attention, an adult with mainly inattentive difficulties can still reach that level without strong restlessness answers. A lower count does not rule ADHD out, and the screener does not tell you which presentation applies.

Inattentive difficulties are quieter than hyperactive ones. A child who daydreams, loses homework and takes hours over simple tasks is less likely to be referred than one who disrupts the class. Research reviews describe girls and women being identified later on average, and suggest that referral patterns, presentation and co-occurring anxiety or low mood all play a part.

In adulthood, people often build workarounds: alarms, lists, a partner who keeps the calendar, working late to catch up. These can hide the difficulty until demands go up, for example with a promotion, a new baby or study alongside work.

Attention problems are common and have many causes. Anxiety, low mood, poor sleep, burnout, grief, menopause, thyroid problems, some medicines and alcohol or other substances can all make it hard to concentrate. So can an overloaded job. Some of these can also sit alongside ADHD.

This is why a screener cannot settle the question. A clinician asks when the difficulties started, whether they come and go with stress or mood, and how they affect different parts of life. The article on ADHD and anxiety in adults looks at that overlap in more detail.

Six questions cannot cover everything. If you want to look at everyday patterns in more detail before an appointment, the ADHD traits test is an original NeuroType reflection across eight areas, including starting tasks, keeping track of time and working memory. It is not a clinical instrument and it does not reproduce the ASRS. It can help you collect examples in your own words, which are often more useful in an appointment than any score.

Consider talking to a GP, family doctor or primary care provider if inattentive difficulties have been with you since childhood, show up at work and at home, and are causing problems you cannot fix with more effort. Bring specific examples and, if you can, someone's memory of you as a child. The routes, costs and waits differ a lot between countries, and the assessment guide by country covers the US, UK, Canada, Australia, New Zealand and Ireland.

If you are struggling to cope or feel unsafe, contact your local emergency number or a crisis line now rather than waiting for an assessment.
