Children with ASD demonstrated significantly higher frequency and longer duration of RSB with objects, body, and sensory behaviors during a systematic behavior sample than both the DD and TD groups. RSB with objects were related to concurrent measures of symbolic capacity and social competence in the second year and predicted developmental outcomes as well as severity of autism symptoms at 3 years in children with communication delays. RSB in the second year appear to be important for early identification and prediction of developmental outcomes.

Repetitive and stereotyped movements in children with autism spectrum disorders late in the second year of life / Lindee MORGAN in Journal of Child Psychology and Psychiatry, 49-8 (August 2008)  

Public ISBD [article]  inJournal of Child Psychology and Psychiatry > 49-8 (August 2008) . - p.826 - 837 Titre : Repetitive and stereotyped movements in children with autism spectrum disorders late in the second year of life Type de document : texte imprimé Auteurs : Lindee MORGAN, Auteur ; Amy M. WETHERBY, Auteur ; Angie BARBER, Auteur Année de publication : 2008 Article en page(s) : p.826 - 837 Langues : Anglais (eng) Mots-clés : Assessment autism-spectrum-disorders developmental-delay infancy repetitive-and-stereotyped-behavior Index. décimale : PER Périodiques Résumé : Objectives: The purpose of this study was to examine group differences and relationships with later developmental level and autism symptoms using a new clinical tool developed to measure repetitive and stereotyped movements (RSM) in young children. Method: Videotaped behavior samples using the Communication and Symbolic Behavior Scales Developmental Profile (CSBS; Wetherby & Prizant, 2002) were coded for children with autism spectrum disorders (ASD; n = 50), developmental delays without ASD (DD; n = 25), and typical development (TD; n = 50) between 18 and 24 months of age. Results: Children with ASD demonstrated significantly higher rate and larger inventory of RSM with objects and body during a systematic behavior sample than both the DD and TD groups. Measures of RSM were related to concurrent measures of social communication and predicted developmental outcomes and autism symptoms in the fourth year for the ASD group. None of the correlations between RSM and autism symptoms remained significant when controlling for CSBS Symbolic level. RSM with objects predicted unique variance in the severity of autism symptoms in the fourth year beyond that predicted by social communication measures alone. Conclusions: This study provides support for the diagnostic significance of RSM in children under 24 months of age and documents the utility of this RSM measurement tool as a companion to the CSBS.
