Self screening questionnaires

Validated questionnaires for ADHD, autism, and functional impact, all run in your browser, nothing is stored or sent anywhere

These are self screening questionnaires, not diagnostic tools. A positive result means it may be worth speaking to your GP or a private clinician, it does not mean you have ADHD or are autistic. A negative result does not rule either condition out. Always speak to a qualified clinician about your own health.

ADHD

ASRS-v1.1

Adult ADHD Self-Report Scale

Developed with the World Health Organization. Part A (6 questions) is the short screener, and 4 or more highlighted responses is a positive screen.

Adults 18 and over · 18 questions · ~5 minutes

Autism

AQ-10

Autism Spectrum Quotient

Developed at the University of Cambridge Autism Research Centre. NICE guideline CG142 says that for adults with possible autism, if a person scores 6 or above on the AQ-10 (or autism is suspected on clinical judgement), a comprehensive assessment should be offered.

Adults 16 and over · 10 questions · ~3 minutes

CAT-Q

Camouflaging Autistic Traits Questionnaire

Measures how much you camouflage autistic traits, through compensation (social scripting), masking (monitoring your behaviour), and assimilation (fitting in). It may be relevant if you suspect you are masking at work or in social situations.

Adults · 25 questions · ~8 minutes

Functional impact

These scales measure how much ADHD is affecting daily life, not whether you have it. Useful at every stage: before a GP referral (a completed scale gives your GP a concrete picture of impact to include with a referral), at assessment (NICE NG87 recommendation 1.3.3 says symptoms should cause at least moderate impairment and occur in 2 or more important settings), and during treatment to track real-world change. The self-report version (WFIRS-S) is completed by the adult about themselves; the parent-report version (WFIRS-P) is completed by a parent about their child.

WFIRS-S

Weiss Functional Impairment Rating Scale, Self Report

Rate how ADHD affects your daily life across seven domains. Items scored Often or Very often highlight where difficulty is reported. CADDRA considers a domain impaired if two items are rated 2 or one item is rated 3.

Adults · self report · 69 questions

WFIRS-P

Weiss Functional Impairment Rating Scale, Parent Report

Rate how your child's ADHD affects their daily life across six domains. The scale can be shared with your child's clinician.
