Language profiles in young children with autism spectrum disorder: A community sample using multiple assessment instruments / R. NEVILL in Autism, 23-1 (January 2019)
[article]
Titre : Language profiles in young children with autism spectrum disorder: A community sample using multiple assessment instruments Type de document : Texte imprimé et/ou numérique Auteurs : R. NEVILL, Auteur ; D. HEDLEY, Auteur ; M. ULJAREVIC, Auteur ; E. SAHIN, Auteur ; J. ZADEK, Auteur ; Eric BUTTER, Auteur ; J. A. MULICK, Auteur Article en page(s) : p.141-153 Langues : Anglais (eng) Mots-clés : assessment autism spectrum disorder communication and language development Mullen scales predictors preschool children Preschool Language Scale Vineland diagnostic observation schedule joint attention preschool-children toddlers outcomes growth characterize associations impairments Psychology Index. décimale : PER Périodiques Résumé : This study investigated language profiles in a community-based sample of 104 children aged 1-3 years who had been diagnosed with autism spectrum disorder using Diagnostic and Statistical Manual of Mental Disorders (5th ed.) diagnostic criteria. Language was assessed with the Mullen scales, Preschool Language Scale, fifth edition, and Vineland-II parent-report. The study aimed to determine whether the receptive-to-expressive language profile is independent from the assessment instrument used, and whether nonverbal cognition, early communicative behaviors, and autism spectrum disorder symptoms predict language scores. Receptive-to-expressive language profiles differed between assessment instruments and reporters, and Preschool Language Scale, fifth edition profiles were also dependent on developmental level. Nonverbal cognition and joint attention significantly predicted receptive language scores, and nonverbal cognition and frequency of vocalizations predicted expressive language scores. These findings support the administration of multiple direct assessment and parent-report instruments when evaluating language in young children with autism spectrum disorder, for both research and in clinical settings. Results also support that joint attention is a useful intervention target for improving receptive language skills in young children with autism spectrum disorder. Future research comparing language profiles of young children with autism spectrum disorder to children with non-autism spectrum disorder developmental delays and typical development will add to our knowledge of early language development in children with autism spectrum disorder.

Titre : Correlates of adaptive behavior profiles in a large cohort of children with autism: The autism speaks Autism Treatment Network registry data Type de document : Texte imprimé et/ou numérique Auteurs : M.

This study examines the adaptive behavior, its association with cognitive ability, gender, age, and symptom severity in children with autism spectrum disorder. Using data from Autism Treatment Network registry, the adaptive behavior profiles were examined in 2538 school-aged children (between 5 and 17 years, mean: 8.8 years, standard deviation: 3.0) who had an overall intelligence quotient and Vineland Adaptive Behavior Scale scores available. The children were grouped according to their intelligence quotient (low intelligence quotient < 70; borderline intelligence quotient = 70-85; average intelligence quotient > 85), age (5-10 and 11-17 years), and gender for the analyses. Significantly lower Vineland Adaptive Behavior Scale scores were found in borderline and average intelligence quotient groups when compared to mean intelligence quotient, while an opposite pattern was seen in the low intelligence quotient group, with better adaptive behavior scores than mean intelligence quotient. Vineland Adaptive Behavior Scale standard scores were positively correlated with intelligence quotient and poorly associated with autism spectrum disorder severity. Younger children had significantly higher Vineland Adaptive Behavior Scale scores. Adjusted comparisons by gender were not significant. Adaptive behavior profiles in the intelligence quotient categories are discussed. This study confirms a positive relationship between adaptive behavior and intellectual function in autism and indicates that children with higher intelligence quotient and older age are specifically impaired, with lower adaptive behavior, highlighting the need for assessment and targeted intervention in these groups. Future directions for research are discussed. En ligne : http://dx.doi.org/10.1177/1362361317733113 Permalink : https://www.cra-rhone-alpes.org/cid/opac_css/index.php?lvl=notice_display&id=379

A series of to-be-imitated actions was presented to 35 children with autism spectrum disorder and 20 typically developing children on an Apple((R)) iPad((R)) by a socially responsive or aloof model, under conditions of low and high motor demand. There were no differences in imitation performance (i.e. the number of actions reproduced within a fixed sequence), for either group, in response to a model who acted socially responsive or aloof. Children with autism spectrum disorder imitated the high motor demand task more poorly than the low motor demand task, while imitation performance for typically developing children was equivalent across the low and high motor demand conditions. Furthermore, imitative performance in the autism spectrum disorder group was unrelated to social reciprocity, though positively associated with fine motor coordination. These results suggest that difficulties in object-directed imitation in autism spectrum disorder are the result of motor execution difficulties, not reduced social motivation.
