The Modified Checklist for Autism in Toddlers, Revised, with Follow-Up (M-CHAT-R/F; Robins et al. 2009) is a 20-item parent-report screening instrument designed to identify children at risk for autism spectrum disorders (ASD). It is revised from the original 23-item M-CHAT, in order to improve psychometric properties and simplify the reading level.

Parents report whether their child usually shows each behavior or not; items are scored at-risk or not-at-risk for ASD. Total score is calculated based on the number of at-risk responses. If a child demonstrates low risk (total score 0–2), no further action is needed. If a child scores in the moderate risk range (total score 3–7), parents should complete the structured M-CHAT-R Follow-Up (M-CHAT-R/F), which elaborates on target behaviors and elicits specific examples from parents. These questions can be administered in interview format with a professional, or they can be self-administered by computer....
