Psychometric properties, factor structure and cross-cultural validity of the quantitative CHecklist for autism in toddlers (Q-CHAT) in an Italian community setting

摘要

Background: In the past decade, several screening instruments have been developed to detect toddlers at risk for autism, both in clinical and unselected samples. We aimed to assess the validity and cross-cultural stability of the Quantitative CHecklist for Autism in Toddlers (Q - CHAT), a quantitative and normally distributed measure of autistic traits, during routine paediatric developmental surveillance in a large Italian community of toddlers.
