The M-CHAT (Modified Checklist for Autism in Toddlers)

The M-CHAT (Modified Checklist for Autism in Toddlers) is a screening tool designed to identify young children who may be at risk for autism spectrum disorder (ASD). It consists of a questionnaire filled out by parents, focusing on a child's behaviors and developmental milestones related to communication, social interaction, and play. The goal is to detect early signs of autism so that further assessment and intervention can occur promptly, supporting better developmental outcomes. It is not a diagnostic test but a helpful step to determine whether a child should be evaluated more thoroughly by a healthcare professional.
