ADHD Test (Adult)
A confidential self-assessment built on the ASRS v1.1, the adult ADHD screener developed with the World Health Organization. In two minutes you get an instant likelihood result and a plain-language PDF report you can keep or bring to a clinician.
What the ASRS screener actually captures
The ASRS Part A screener focuses on the six questions that best predict adult ADHD, covering both inattentive and hyperactive-impulsive features.
The six strongest items
Of the full ASRS, these six Part A questions were found to be the most predictive of adult ADHD. They cover finishing tasks, organizing, remembering, fidgeting, and restlessness.
Both presentations
The items span inattentive features like losing focus and disorganization, and hyperactive-impulsive features like restlessness and feeling driven by a motor.
A persistence lens
The screener asks how you have felt and behaved over the past six months, since ADHD is defined by patterns that persist rather than occasional off days.

Methodology & sources
This test reproduces the six Part A screener items of the Adult ADHD Self-Report Scale (ASRS) v1.1, developed by Kessler and colleagues with the World Health Organization (2005). The official ASRS uses a shaded-box scoring method: certain answers (Sometimes, Often, or Very Often, depending on the item) fall inside a darkly shaded box, and four or more shaded responses across the six questions is a positive screen that suggests symptoms consistent with adult ADHD and warrants further evaluation. We report this shaded-box result because it is the validated clinical screen.
Alongside the shaded-box screen, we also provide a simple summed score for context, where each item is rated from 0 (never) to 4 (very often) for a total of 0 to 24. We band that summed score as 0 to 7 low likelihood, 8 to 15 moderate, and 16 to 24 high, which is an educational adaptation, not part of the original validated scoring. This test is provided for education and self-reflection. It is not a diagnosis. Only a qualified clinician can assess ADHD, typically through a structured interview, developmental history, and review of how symptoms affect daily life.

ADHD Test (Adult) FAQ
What is the ASRS adult ADHD test?
The ASRS v1.1 is a short, validated screener developed with the World Health Organization to flag adults who may have ADHD. The Part A version used here is the six most predictive questions. It indicates likelihood, not a diagnosis.
What does a positive screen mean?
On the official shaded-box scoring, four or more shaded responses across the six questions is a positive screen, meaning your symptoms are consistent with adult ADHD and a fuller evaluation is worthwhile. It does not confirm ADHD on its own.
Is this test a diagnosis?
No. It is for education and self-reflection only. Only a qualified clinician can diagnose ADHD, usually through a detailed interview, your developmental history, and a look at how symptoms affect your daily life. A positive screen is a reason to seek that assessment.
Can adults really have ADHD?
Yes. ADHD is a lifelong neurodevelopmental difference, and many adults are identified later in life, especially those whose symptoms were missed in childhood. Adult ADHD is real, common, and supportable.
Is the test really confidential?
Yes. It runs entirely in your browser. Your answers are never sent to a server, never stored, and never linked to you. No account is needed, and the optional PDF is generated on your own device.
