Revised M-CHAT Improves Autism Screening for Toddlers

February 4, 2014 10:55 am Published by

The Modified Checklist for Autism in Toddlers, Revised with Follow-Up (M-CHAT-R/F; Robins, Fein, & Barton, 2009) is a 2-stage parent-report screening tool to assess risk for Autism Spectrum Disorder (ASD). M-CHAT-R is valid for screening toddlers between 16 and 30 months of age.

The American Academy of Pediatrics (AAP) recommends that all children receive autism screening at 18 and 24 months of age, and the M-CHAT-R/F is one of the AAP’s recommended tools.

The primary goal of the M-CHAT-R is to maximize sensitivity, meaning to detect as many cases of ASD as possible. Therefore, there is a high false positive rate, meaning that not all children who score at risk will be diagnosed with ASD. To address this, the researchers have developed Follow-Up questions (M-CHAT-R/F). Even with the Follow-Up questions, a significant number of the children who screen positive on the M-CHAT-R will not be diagnosed with ASD; however, these children are at high risk for other developmental disorders or delays, and therefore, evaluation is warranted for any child who screens positive.

The M-CHAT-R/F is available for free download for clinical, research, and educational purposes at www.mchatscreen.com.
