Attachment 1. Methodology

This test looks at six everyday patterns often associated with adult ADHD: attention and follow-through, getting started on tasks, physical and mental restlessness, impulsivity, emotional reactivity, and a sense of time. Eighteen questions ask how often each pattern shows up in daily life right now, and the result reflects the overall frequency across all six.

This is an original set of questions, built independently for this site. It sits in the same research territory as a well-known adult-ADHD screening checklist, named directly in the FAQ below, but it does not reuse that checklist's wording, structure, or scoring — the two are not interchangeable.

What this test measures is a present-day snapshot, not a childhood history and not whether a pattern shows up the same way at work, at home, and everywhere in between — both of which a clinical diagnosis requires. It also can't rule out that a similar pattern of answers comes from something else entirely: anxiety, low mood, poor sleep, or simply a demanding stretch of life. For general background, see the National Institute of Mental Health; for guidance on next steps, see the NHS.

This test is not a diagnostic instrument, and it is not a substitute for an assessment by a qualified professional.

Attachment 2. Frequently Asked Questions

Can this test diagnose ADHD?

No. A diagnosis can only come from a qualified professional — a psychologist, psychiatrist, or primary care provider — usually through a review of symptom history, ruling out other explanations, and often input from people who know the person well. This test is a single self-report sitting: it doesn't establish a childhood history of these patterns or confirm that they show up the same way across different parts of life, both of which a real diagnosis requires.

Is this the actual ASRS test?

No. The ASRS (Adult ADHD Self-Report Scale) is a specific, copyrighted screening checklist developed in connection with the World Health Organization and intended for use during a clinical visit. This test asks its own original set of questions, covering similar ground — attention, task initiation, restlessness, impulsivity, emotional regulation, and time management — but it doesn't copy, translate, or rehost that checklist's items, format, or scoring.

How accurate is this test?

It's an honest snapshot of how often these patterns show up right now, based on one sitting. It can't rule out that a similar answer pattern comes from something other than ADHD — anxiety, low mood, poor sleep, or an unusually demanding stretch of life can all produce a similar picture. It isn't validated the way a structured clinical interview is.

What should I do with my result?

Treat it as information about a current pattern, not a verdict on who you are. If your result comes back frequent or pronounced, raising it in conversation with a professional the next time it's convenient is a reasonable, ordinary step — there's no need to treat it as urgent.
