Using the M-CHAT-R/F to Identify Developmental Concerns in a High-Risk 18-Month-Old Sibling Sample

摘要

ObjectiveGiven the high autism spectrum disorder (ASD) recurrence risk in younger siblings, it is important to identify early ASD markers within this high risk population. Although there is increasing evidence that the Modified Checklist for Autism in Toddlers-Revised, with Follow-Up Interview can identify many low-risk children during the second year of life, there has yet to be a study of how the M-CHAT-R/F functions in a high-risk sibling population at very young ages.
