The study assessed the feasibility of using a Turkish-version of the Modified Checklist for Autism in Toddlers, Revised (M-CHAT-R/F) as a screening tool for an urban low risk population of young children. M-CHAT-R/F was completed for 6712 children between ages 16 and 36 months living in Istanbul, Turkey. Autism Diagnostic Observation Schedule-2 was served as the main measure for diagnosis. M-CHAT-R/F screen was positive for 9.8% of children. At follow up interview, 39.7% of initial screen-positive children met criteria for ASD. The study identified 57 (1 in 117) children with ASD (0.8%; 95% CI 0.063-1.05%). M-CHAT-R/F performed comparably in Turkey as in United States. Implications of the study for future universal screening for autism in Turkey is also discussed.
