Sintesi	The Autism Spectrum Quotient (AQ) is a brief self- or observer-report measure of autism-spectrum traits in adolescents and adults. Developed by Simon Baron-Cohen and colleagues in 2001, the original 50-item version (AQ-50) quantifies propensity toward autism across five domains: social skills, attention to detail, attention switching, communication, and imagination. The 10-item version (AQ-10) serves as a rapid screening tool. The AQ is not diagnostic but identifies individuals who warrant formal autism evaluation.	The Social Communication Questionnaire (SCQ) is a 40-item parent-report measure of autism-spectrum symptoms in children ages 4–15 years. Developed by Michael Rutter, Ann Bailey, and Catherine Lord in 2003, it serves as a brief screening tool for autism spectrum disorder. The SCQ asks parents to recall or report current child behaviors in three domains: reciprocal social interaction, communication, and restricted/repetitive behaviors/interests. It is frequently used in primary care, developmental pediatrics, and research settings to identify children warranting comprehensive autism evaluation.
