Simple Test
ADHD Self Check
Adult ADHD self-screening based on the WHO ASRS-v1.1 18-item scale, covering six core symptom clusters. Not a medical diagnosis.
This quick screener uses WHO ASRS v1.1 items plus functional impact checks. Answer 16 questions to review current symptoms, childhood history, and daily-life effects together.
Test structure
- • 6 current-symptom items: frequency of inattention/hyperactivity
- • 5 childhood items: whether it was present from early development
- • 5 daily-impact items: functional impairment at work/relationships
- All questions use a 5-point scale (Never–Very Often).
Notes
- • Results are for self-screening only and are not a diagnosis.
- • High scores: see a psychiatrist and consider CAT or detailed evaluation.
- • Similar symptoms can appear with recent stress, anxiety, or depression.
Questions and options are fixed in order, and you can go back anytime.
ADHD Self Check is an 18-item self-screening tool grounded in the World Health Organization's Adult ADHD Self-Report Scale (ASRS-v1.1). It measures two axes — inattention and hyperactivity/impulsivity — across six symptom clusters: ① missing details, ② difficulty sustaining attention, ③ organizational difficulty, ④ trouble starting and finishing tasks, ⑤ restlessness and overactivity, and ⑥ impulsivity and interrupting others. OgleOgle's version is fully free, requires no sign-up, and takes three to five minutes.
It's most useful when concrete daily patterns start to compound: "my attention keeps slipping in meetings," "I push every deadline to the last moment," "my desk is always chaotic," "I start five things and finish none," "I keep forgetting important dates and commitments" — and the cost on work, relationships, or finances has become noticeable. Parents who notice similar patterns in their children, or adults reviewing their own childhood history while exploring family patterns, also find it a useful starting point.
Each question asks how often a behavior occurred over the past six months on a five-point scale — "never, rarely, sometimes, often, very often." The first six items (Part A) form the high-discrimination screener; a score above the Part A threshold flags the case as "professional evaluation recommended." The result screen shows the total score, a per-cluster breakdown across the six symptom clusters, a plain-language behavioral summary, and guidance on whether to consult a specialist.
Important medical disclaimer — this screening is not a clinical diagnosis. A formal ADHD diagnosis requires evaluation by a psychiatrist, including clinical interview, developmental and family history, school or workplace functional assessment, and ruling out co-occurring conditions (depression, anxiety, sleep disorders, thyroid issues, medication side effects). A high screening score does not mean you have ADHD, and a low score does not rule it out. If daily difficulties are real and persistent, please consult a qualified mental-health professional.
FAQ — Is my data stored? No. All responses are processed in your browser and never sent to a server. Can it be used for children? ASRS-v1.1 is designed for adults (18+); children and adolescents should use age-appropriate scales like KARS or K-CBCL. Do results change over time? Sleep, stress, and overall condition can shift scores slightly, so retaking the test a few days apart helps reveal a more stable pattern.
