Adult ADHD
Self-Screener

18 questions based on the WHO Adult ADHD Self-Report Scale (ASRS-v1.1) framework — the most widely used validated ADHD screener for adults. Takes about 5 minutes.

Not a diagnosis. This screener identifies symptoms consistent with ADHD — it cannot diagnose you. Only a qualified clinician can do that. Use this as a starting point for a conversation with your GP or psychiatrist. ADHD is frequently underdiagnosed — especially in women, late-diagnosed adults, and those who have developed strong compensatory strategies.

Frequently Asked Questions
Can adults have ADHD?
Yes — ADHD is a lifelong neurodevelopmental condition, not just a childhood disorder. Approximately 2.5–4% of adults meet diagnostic criteria, though many are undiagnosed. Adult ADHD often presents differently than in children: rather than obvious hyperactivity, it may manifest as chronic disorganisation, difficulty completing tasks, time blindness, emotional dysregulation, relationship difficulties, or an inner sense of restlessness and underachievement despite high intelligence. Many adults are diagnosed for the first time in their 30s, 40s, or later.
What's the difference between inattentive and hyperactive ADHD?
ADHD has three presentations: predominantly inattentive (ADHD-PI), predominantly hyperactive-impulsive (ADHD-PH), and combined type (ADHD-C). The inattentive type is characterised by difficulty sustaining attention, frequent distraction, forgetfulness, and losing things — and is more common in women and often missed in childhood because it's less disruptive. The hyperactive-impulsive type involves restlessness, talking excessively, interrupting, difficulty waiting, and acting without thinking. Most adults with ADHD have the combined type, though hyperactivity tends to decrease with age while inattention often persists.
What should I do if my score suggests ADHD?
Bring your results to your GP or a psychiatrist. A formal ADHD assessment typically involves a structured clinical interview, rating scales, and sometimes cognitive testing. It also requires ruling out other conditions (anxiety, depression, thyroid disorders, sleep disorders) that can mimic ADHD symptoms. Treatment for adult ADHD is highly effective and includes medication (stimulants and non-stimulants), CBT adapted for ADHD, and coaching. Many people describe an accurate ADHD diagnosis as life-changing — finally understanding a lifetime of struggles and having effective tools to address them.
How to Use the Adult ADHD Self-Screener

Complete the WHO ASRS-v1.1 screening questionnaire and understand your results.

01
Answer all 18 questions honestly
Each question asks how often you've experienced a specific symptom over the past 6 months. Choose the option that genuinely reflects your experience, not how you wish it were.
02
Focus on Part A (questions 1–6)
These six questions are the most clinically significant. The screener flags Part A separately because these items have the highest predictive value.
03
Review your subscores
Results are broken into inattention and hyperactivity-impulsivity subscores. Seeing which is higher can be useful information for conversations with a clinician.
04
Read the medical disclaimer
This is a screening tool, not a diagnosis. A positive screen means it may be worth discussing with a doctor — not that you have ADHD.
💡
💡 ADHD is significantly underdiagnosed in adults, particularly in women. If the results resonate strongly, the next step is a proper assessment with a psychiatrist or psychologist.
