Modified Checklist for Autism in Toddlers
The M-CHAT was developed at the University of Connecticut's Department of Psychology, and is designed to screen children aged 16 to 30 months for an autism spectrum disorder (ASD).
The 23-item, parent-completed form generally takes five to seven minutes to be completed and a brief time for staff to score.
Note: The American Academy of Pediatrics (AAP) now recommends administering the screen at two visits: 18 months and again at 24 months.
Overview of scoring. The response categories are: "Yes" and "No". The threshold for identifying at-risk children is a "No" response to two or more of the critical items (identified in the scoring instructions) OR failure of any three items. Please consult the M-CHAT Web site instructions.
