Early expressive and receptive language trajectories in high-risk infant siblings of children with autism spectrum disorder / Julie LONGARD in Autism & Developmental Language Impairments, 2 (January-December 2017)
[article]
Titre : Early expressive and receptive language trajectories in high-risk infant siblings of children with autism spectrum disorder Type de document : Texte imprimé et/ou numérique Auteurs : Julie LONGARD, Auteur ; Jessica BRIAN, Auteur ; Lonnie ZWAIGENBAUM, Auteur ; Eric DUKU, Auteur ; Chris MOORE, Auteur ; Isabel M. SMITH, Auteur ; Nancy GARON, Auteur ; Peter SZATMARI, Auteur ; Tracy VAILLANCOURT, Auteur ; Susan E. BRYSON, Auteur Langues : Anglais (eng) Index. décimale : PER Périodiques Résumé : Background 152 LR controls, 52% boys) followed from age 6 or 12 months to 36 months. Based on independent, best-estimate clinical diagnoses at 36 months, HR participants were classified as HR-ASD (n=94; 69% boys), or HR-N (n=277; 52% boys); the sample also included 152 LR controls (52% boys). Expressive and receptive language trajectories were examined based on corresponding domain standard scores on the Mullen Scales of Early Learning (MSEL) at 6, 12, 24, and 36 months. In the combined sample of HR and LR infants, semi-parametric group-based modeling was used to identify distinct trajectories in MSEL standard scores.ResultsA 3-group solution provided optimal fit to variation in both expressive and receptive language, with the following patterns of scores: (1) inclining from average to above average, (2) stable-average, and (3) declining from average to well below average. For both expressive and receptive language, membership in these trajectories was related to 3-year diagnostic outcomes.ConclusionsAlthough HR-ASD, HR-N, and LR control infants were in each trajectory group, membership in the declining trajectory (expressive and/or receptive) was associated with an ASD diagnosis.ImplicationsEvidence of declining trajectories in either expressive or receptive language may be a risk marker for ASD in a high-risk sample.
