Clinical screeners on The Quiz Hub draw from published instruments used in research and primary care. The Adult ADHD Self-Report Scale (ASRS), developed by Kessler et al. (2005) with WHO support, screens for inattention and hyperactivity in adults. The Obsessive-Compulsive Inventory-Revised (OCI-R), published by Foa et al. (2002), measures washing, checking, ordering, and other obsessive-compulsive symptoms. The Patient Health Questionnaire (PHQ-9) and Generalized Anxiety Disorder scale (GAD-7) are widely used for mood and anxiety screening in outpatient settings. Our online versions shorten these tools and rewrite items in plain language.

That abbreviation trades research comparability for accessibility. A positive screening signal means your answers suggest symptoms frequent enough to discuss with a clinician. It does not mean you have ADHD, depression, or any named disorder. Diagnosis requires structured evaluation, often including childhood history, functional impairment across settings, and exclusion of medical or substance causes.
