The M-CHAT-R stands for the revised version of the “Modified Checklist for Autism in Toddlers.” It is a commonly employed developmental screening tool used to detect autism spectrum disorder in children aged 16 – 30 months. The survey consists of 20 questions that should take 5 – 10 minutes to complete.
“Developmental screening” is a general term to describe the practice of observing and tracking a child’s development. When monitoring a child’s progress, professionals look to multiple areas of development such as motor skills, cognitive and emotional development. Screenings helps professionals determine whether a more in-depth assessment is needed to confirm an official diagnosis.
The M-CHAT-R is not a diagnostic tool, but rather a screening tool used to guide parents and professionals to determine whether a more in-depth autism evaluation should be performed. A positive result on the M-CHAT-R does not necessarily mean a child has ASD, but rather it indicates a higher likelihood of ASD or a similar disorder.
