Do I have ADHD? The first step starts with you.

Before you take the self-test — please read this

I'm Stephan, 48, diagnosed with ADHD at 47. I'm not a psychiatrist, not a therapist, not a doctor. I'm a software engineer who, after decades of feeling "something's not right with me," eventually stumbled across an ASRS self-test that made me properly nervous for the first time. Three months later I had a clinical diagnosis.

This page doesn't provide a self-test that diagnoses you. No such test exists. What exists is a scientifically developed screening scale that indicates whether suspicion of ADHD is strong enough for you to take the next step — an evaluation by someone who is licensed to make the diagnosis. That scale is what I'm describing on this page.

If you landed here because you're currently asking yourself whether what you observe in yourself could be ADHD: that's a good reason to keep reading. And an even better reason to book an appointment at an ADHD evaluation practice by the end.

What the ASRS-V1.1 is (and isn't)

The Adult ADHD Self-Report Scale (ASRS-V1.1) is the most widely used standardized screening scale for ADHD in adults. It was developed by a World Health Organization (WHO) workgroup together with the WHO World Mental Health Survey Initiative and published in 2005 by Kessler et al. in Psychological Medicine ("The World Health Organization Adult ADHD Self-Report Scale (ASRS): a short screening scale for use in the general population"). The questions match DSM-IV/DSM-5 criteria, worded for how ADHD manifests in adults — not how it shows up in children.

The full scale has 18 items. The short form — the 6-item screener (Part A) — contains the six questions Kessler et al. found correlated most strongly with a clinical ADHD diagnosis. These six are what many online self-tests use.

What the ASRS can: indicate whether clinically relevant suspicion of ADHD exists.

What the ASRS cannot: make a diagnosis. No one receives an ADHD diagnosis through an online test. A diagnosis requires a clinical interview, often with childhood history-taking, sometimes with additional neuropsychological testing. In the US this is typically done by a psychiatrist, sometimes a psychologist with relevant experience; in many European systems it's a specialist physician for psychiatry and psychotherapy.

Why late-diagnosed ADHD often stays hidden for decades

In 1995 Sari Solden's Women with Attention Deficit Disorder: Embrace Your Differences and Transform Your Life effectively closed the gap left by the then-dominant picture of "ADHD = hyperactive boy." Her finding — three decades of clinical work later largely confirmed — is that women in particular, and quietly-compensating men, are chronically underdiagnosed, often carrying decades of shame as a companion before the diagnosis finally lands. My own path matches that pattern exactly.

Three reasons that fit my own case and recur throughout the literature:

High-functioning compensation. Many adults with ADHD have built strategies over decades that allow functioning — above-average intellect, hyperfocus on interesting domains, workaholic patterns, hard self-discipline. That works for a long time. Until it doesn't (burnout, layoff, family crisis), and suddenly the deficit lies exposed.

False stereotypes. The classic picture is the hyperactive boy who can't sit still. Adult ADHD presentation — especially in women, but not only — often looks completely different: chronic exhaustion, RSD (Rejection Sensitive Dysphoria), emotional dysregulation, "inner restlessness rather than outer," difficulty with work organization despite high intelligence. That rarely gets recognized because it doesn't match the textbook image.

Comorbid diagnoses mask it. Many adults receive diagnoses over the years like depression, anxiety disorders, burnout. That isn't wrong — these comorbidities are real and need treatment. But if the underlying ADHD stays undetected, the person carries the wrong primary diagnosis. The NCS-R study by Kessler et al. (2006) in the American Journal of Psychiatry showed in a US population sample that only about 11% of adults with ADHD had received treatment for the disorder within the past 12 months — against a prevalence of around 4.4% in the adult general population.

When the self-test flags something — what next?

Up front: an elevated ASRS score isn't an emergency and isn't a crisis. It's a signal that further evaluation makes sense. What you can do — in this order:

1. Write down what you observe. Concrete situations. "I regularly forget where I parked." "I've never sustained a routine for more than six weeks." "Trivial criticism throws me off for days." Concrete examples help enormously in the first appointment — more than abstract self-description.

2. See your primary care doctor. That's the standard entry into the mental health pathway. Ask for a referral to a psychiatrist or psychologist with ADHD experience — "I have an elevated ASRS score and suspect ADHD" is a normal reason and not an embarrassing one.

3. Plan for patience. Waiting times for an appointment at an ADHD-specialized practice can run several months in many countries. In the meantime, reading helps — and honest self-mapping. Russell Barkley, Edward Hallowell, Sari Solden are good starting authors. You'll recognize yourself in much of it, or you won't. Both are information.

4. Consider differential diagnoses. Symptoms like concentration problems, exhaustion, emotional dysregulation aren't unique to ADHD. Thyroid dysfunction, depression, sleep apnea, iron deficiency, post-traumatic stress disorder can look similar. A good initial workup rules these out. Anyone who walks into a practice with "I think I have ADHD" and isn't open to other explanations walks out with the wrong diagnosis.

Why a habit-tracker app on this page?

This page lives on dopaloop.app, and I build DopaLoop — a habit-tracker app for ADHD brains. I'm not going to pretend the link to this page is here by accident. But I'm also not going to claim an app replaces a diagnosis or is a tool for the pre-diagnosis phase.

If you're currently in the "I suspect I might have ADHD" stage — don't install an app. Make the appointment. Read an entry-level classic (e.g., "Driven to Distraction" by Hallowell and Ratey). See whether the description hits.

If you're post-diagnosis and looking for a daily tool that doesn't work against your brain — DopaLoop may make sense. Goals-First, intensity 0–5 instead of binary, local on the device, no streak-shaming mechanics. (What Goals-First means concretely.)

But the app isn't the solution to a diagnosis problem. Only the diagnosis itself solves that — and the path there goes through a clinical practice, not the App Store.
