How does the Modified Checklist for Autism in Toddlers, Revised (M-CHAT-R/F) compare to other screening methods in terms of sensitivity and specificity for identifying Autism Spectrum Disorder in young children?

No direct comparative evidence between M-CHAT-R/F and other screening methods was identified. M-CHAT-R/F demonstrates high sensitivity and variable specificity, making it suitable for initial ASD screening in young children, although false-positive rates can affect specificity.
