Adult ADHD Test

Yes. Your overall score and your dimension scores (inattention, hyperactivity, impulsivity) are entirely free and sign-up free. The detailed report with DSM-5 sub-type classification and personalised recommendations is premium.

About 10 minutes for the 45 questions across 7 chapters. You can navigate back at any time, and your answers are preserved if you interrupt — you can resume where you left off.

No. It's a screening tool based on the WHO ASRS-v1.1. An ADHD diagnosis can only be made by a qualified health professional (neuropsychologist, psychiatrist, ADHD-trained physician) after a clinical interview, a retrospective review of childhood (WURS or equivalent), and sometimes additional neuropsychological tests (sustained attention, executive function, processing speed). This test gives you a strong or weak signal, but only a full assessment can confirm ADHD and rule out differential diagnoses.

On the Adult ADHD Self-Report Scale version 1.1 (ASRS-v1.1), published by Kessler et al. in 2005 in Psychological Medicine, in collaboration with the WHO. The 18 core items mirror the DSM-5 ADHD criteria.

The DSM-5 distinguishes three presentations: predominantly inattentive (focus difficulty, distractibility, forgetfulness), predominantly hyperactive-impulsive (inner restlessness, quick decisions, interrupting), and combined (both). Our premium results classify your profile along this grid.

The ASRS-v1.1 shows a 68.7 % sensitivity and 99.5 % specificity in adults (Kessler et al., 2005). In plain terms: it avoids almost all false positives (if it flags you, there's a real signal), at the cost of some false negatives (a low score doesn't completely rule out ADHD, especially in pure inattentive presentations). That's why it's used as a first-line screening tool by many clinicians worldwide. Still a screening, not a diagnosis — a clinical assessment is needed to confirm.

Yes. The ASRS-v1.1 is validated for adults across all genders. ADHD in women is historically under-diagnosed — more inattentive presentation, less visible motor restlessness, symptoms masked by anxiety or perfectionism. Screening can open the conversation with a specialist.

Yes, as often as you want. Your life context, stress level and symptom awareness can evolve — a new run can refine your read, especially after a rough stretch or a stabilisation phase.

If your score suggests a tendency consistent with ADHD, the next step is a consultation with a neuropsychologist or a psychiatrist. You can print your results or show your report to kick-start the assessment — it saves time in the appointment. If your score is low but you're struggling in daily life, the differential report may point to another track (anxiety, burn-out, high sensitivity) that also deserves a fitting consultation.

Common path: primary-care doctor → referral to a psychiatrist, a neuropsychologist, or an adult ADHD specialist centre. Waiting times for specialist centres range from 6 months to 2 years depending on the region. Faster alternative: a private neuropsychologist or psychiatrist trained in adult ADHD (variable fees, partial coverage). A diagnosis may grant access to long-term care coverage and workplace or academic accommodations after evaluation.
