Multi-informant assessment of siblings of youth with autism spectrum disorder: Parent-child discrepancies in at-risk classification

This study helps to address gaps in the literature on assessment of emotional and behavioral functioning of TD siblings of youth with ASD. The results highlight the importance of utilizing both parent- and self-report when identifying TD siblings at-risk for maladjustment. Although few siblings were considered at-risk, those who were identified were not usually identified as such on both informants' reports, and a variety of sibling- and parent-factors were associated with differences in at-risk classification. Thus, inclusion and examination of both parent- and self-report of TD sibling psychological functioning is vital for accurately identifying numbers of TD siblings at-risk of maladjustment.
