M-CHAT-R/F · autism screening
A two-stage instrument, with parent report and a follow-up interview when indicated, for screening in early childhood.
Conditions of use
Use the complete M-CHAT-R/F and algorithm, respecting the follow-up stage. The official page identifies the 2009 instrument and provides files with a visual update from March 2025.
Limits and context
Screening does not confirm autism or exclude other developmental differences. Omitting follow-up increases false positives. Publication in an app or website requires a licence; this record provides only official access.
Catalogued source record. Implementation on ELUCENIA and independent scientific review pending.
