The Modified Checklist for Autism in Toddlers (M-CHAT) is a validated developmental screening tool for toddlers between 16 and 30 months of age. It is designed to identify children who may benefit from a more thorough developmental and autism evaluation. The screening can be administered and scored as part of a well-child check-up, and also can be used by specialists or other professionals to screen for developmental delay and autism.
The M-CHAT is designed to be administered to parents/guardians and interpreted by pediatric providers in the context of developmental surveillance. The most recent M-CHAT assessment has been updated to the new version, also known as M-CHAT-R or M-CHAT-R/F. The revised tool has a reduced false positive rate (which means fewer children are given a “high risk” result when they truly do not have autism). It also has a higher sensitivity (which means more children who truly have autism spectrum disorder are given a “high risk” result).
Fast and easy to use, the PTI App version of the M-CHAT-R is an economical, reliable and validated method to screen. Questions are presented one at a time with a single click answer to advance to the next question. The question format automatically adapts to the respondents device (smartphone, tablet or PC) making the PTI App version of the M-CHAT-R ideal for mobile devices.
Using PTI data services, when a questionnaire is complete it is immediately scored electronically and an in-depth report with summary and trending analysis is generated. Results can be printed, loaded into an EMR/EHR and are available as a PDF. The M-CHAT-R can be used with the M-CHAT-F further guiding the provider with more in-depth information.
