Method & sources

This site uses published, peer-reviewed instruments with their original scoring rules. Here is how each one works, where it comes from, and what its limits are.

Principles

Only validated cut-offs are used to flag a result. Tasks without population norms are shown descriptively.
Results are worded as 'consistent with' or 'below the cut-off' — never 'you have'.
Everything runs in your browser. Nothing is sent or stored on a server.
Translations of questionnaires are unofficial unless stated; the validated English wording is always shown alongside.

What clinicians look for

ADHD (DSM-5-TR): persistent inattention and/or hyperactivity–impulsivity, with several symptoms before age 12, present in two or more settings, and clearly interfering with life. In adults, hyperactivity often shows up as inner restlessness; difficulty regulating emotions and a poor sense of time are common.

Autism (DSM-5-TR / ICD-11): lasting differences in social communication and interaction, together with restricted or repetitive behaviours, interests or sensory responses. These are present from early development, though they may only become obvious when social demands exceed someone's capacity — or are hidden by camouflaging.

High intellectual ability: usually defined as an IQ of about 130 or more (top ~2%), measured with a standardised, normed test. Fluid reasoning — solving new problems like matrices and series — is central to it. Popular checklists of 'gifted traits' (e.g. 'overexcitabilities') have weak scientific support and are not used for scoring here.

Instruments

ASRS v1.1 Screener

The World Health Organization's 6-question adult ADHD screener — the most widely used first step before an ADHD assessment.

Kessler, R. C., Adler, L., Ames, M., et al. (2005). The World Health Organization Adult ADHD Self-Report Scale (ASRS): a short screening scale for use in the general population. Psychological Medicine, 35(2), 245–256.

AQ-10

The 10-question Autism Spectrum Quotient from the Autism Research Centre, Cambridge. Recommended by the UK's NICE as a first-line adult screener.

Allison, C., Auyeung, B., & Baron-Cohen, S. (2012). Toward brief "red flags" for autism screening: the short Autism Spectrum Quotient and the short Quantitative Checklist in 1,000 cases and 3,000 controls. Journal of the American Academy of Child & Adolescent Psychiatry, 51(2), 202–212.

RAADS-14 Screen

14 questions covering social understanding, social anxiety and sensory sensitivity — and whether each trait was present when you were young.

Eriksson, J. M., Andersen, L. M., & Bejerot, S. (2013). RAADS-14 Screen: validity of a screening tool for autism spectrum disorder in an adult psychiatric population. Molecular Autism, 4(1), 49.

CAT-Q

Measures camouflaging — consciously copying, masking or scripting social behaviour. High camouflaging can hide autistic traits from screeners, especially in women.

Hull, L., Mandy, W., Lai, M.-C., et al. (2019). Development and Validation of the Camouflaging Autistic Traits Questionnaire (CAT-Q). Journal of Autism and Developmental Disorders, 49(3), 819–833.

Reasoning challenge

Up to 18 puzzles — matrices plus number and letter series — that rise in difficulty. Fluid reasoning is the core ability measured by IQ tests.

Condon, D. M., & Revelle, W. (2014). The International Cognitive Ability Resource: Development and initial validation of a public-domain measure. Intelligence, 43, 52–64. (Item formats inspired the procedurally generated puzzles; no ICAR items are used.)
