Studies focused on siblings of children with ASD also have unrealized potential for contributing to ASD etiologic research. Moving targeted time of enrollment back from infancy toward conception creates tremendous opportunities for optimally studying risk factors and risk biomarkers during the pre-, peri- and neonatal periods. By doing so, a traditional sibling study, which already incorporates close developmental follow-up of at-risk infants through the third year of life, is essentially reconfigured as an enriched-risk pregnancy cohort study. This review considers the enriched-risk pregnancy cohort approach of studying infant siblings in the context of current thinking on ASD etiologic mechanisms. It then discusses the key features of this approach and provides a description of the design and implementation strategy of one major ASD enriched-risk pregnancy cohort study: the Early Autism Risk Longitudinal Investigation (EARLI).

Predictors of Pragmatic Communication in School-Age Siblings of Children with ASD and Low-Risk Controls / K. J. GREENSLADE in Journal of Autism and Developmental Disorders, 49-4 (April 2019)  

Public ISBD [article]  inJournal of Autism and Developmental Disorders > 49-4 (April 2019) . - p.1352-1365 Titre : Predictors of Pragmatic Communication in School-Age Siblings of Children with ASD and Low-Risk Controls Type de document : Texte imprimé et/ou numérique Auteurs : K. J. GREENSLADE, Auteur ; E. A. UTTER, Auteur ; R. J. LANDA, Auteur Article en page(s) : p.1352-1365 Langues : Anglais (eng) Mots-clés : Autism  Broad autism phenotype  High risk siblings  Joint attention  Pragmatic language  Social-communication Index. décimale : PER Périodiques Résumé : Little empirical evidence exists about school-age pragmatic communication or predictors in siblings at heightened familial risk for ASD (HR) and low-risk (LR) controls. The Pragmatic Rating Scale-School-Age (Landa unpublished) was scored for 49 HR siblings and 18 LR controls at 8-12 years. Social-communication and language measures were collected between 14 and 36 months. At 36-months, siblings were classified as ASD (HR-ASD, n = 15), broad autism phenotype (HR-BAP, n = 19), or typically developing (HR-TD, n = 15). Results revealed a pragmatic continuum with significantly better scores for HR-TD than HR-BAP or HR-ASD, and HR-BAP than HR-ASD. Per regression models including all participants, 14-month joint attention initiations predicted school-age pragmatic communication, as did 24-month social-communication and expressive language scores. Early joint attention, social-communication, and language abilities contribute to later pragmatic functioning.
