/**
 * AQ-10 — Autism Spectrum Quotient, 10-item version (adults).
 *
 * Recommended by NICE (UK) for quick screening of autistic traits in
 * adults. Each item is answered on a 4-point agree/disagree scale but
 * scores binary: one point per item answered in the trait direction
 * ("agree" on items 1, 7, 8, 10; "disagree" on the rest, modeled here as
 * `reverseScored`). A total of 6 or more suggests referral for a
 * specialist autism assessment (Allison et al., 2012). Free to use.
