Spontaneous Expressive Language Profiles in a Clinically Ascertained Sample of Children With Autism Spectrum Disorder / Hannah R. THOMAS in Autism Research, 14-4 (April 2021)
[article]
Titre : Spontaneous Expressive Language Profiles in a Clinically Ascertained Sample of Children With Autism Spectrum Disorder Type de document : Texte imprimé et/ou numérique Auteurs : Hannah R. THOMAS, Auteur ; Tara ROONEY, Auteur ; Morgan COHEN, Auteur ; Somer L. BISHOP, Auteur ; Catherine LORD, Auteur ; So Hyun KIM, Auteur Article en page(s) : p.720-732 Langues : Anglais (eng) Mots-clés : instrument language psychometrics Index. décimale : PER Périodiques Résumé : Children with autism spectrum disorder (ASD) have varying degrees of language impairment across multiple domains, which may include deficits in syntactic, pragmatic, and/or semantic skills. The heterogeneity of language profiles within ASD, coupled with the limited scope of existing standardized language measures, makes a comprehensive assessment of language impairments in ASD challenging. The Observation of Spontaneous Expressive Language (OSEL) is a new measure developed to capture children's spontaneous use of language in a naturalistic setting. The current study used the OSEL to examine the patterns of spontaneous expressive language abilities of 87 clinically ascertained children with ASD from 2 to 12?years. As expected, children with ASD were significantly more impaired in their spontaneous use of language compared to typically developing peers. Syntax and narrative skills continued to increase with age from toddler to elementary school years in cross-sectional comparisons. Pragmatic skills improved form toddler to preschool years but remained stable from preschool to elementary school years. Preliminary data also demonstrated significant improvements in OSEL syntax scores over time for a subset of children followed longitudinally (n = 8). Children with ASD consistently showed more impairments in spontaneous expressive language captured on the OSEL compared to language skills measured by other more structured standardized assessments, despite moderate convergent validity among those measures. Results suggest that impairments in the spontaneous and functional use of expressive language persist into middle childhood for many children with ASD, and a comprehensive assessment approach can lead to more precisely targeted treatment addressing specific language profiles. LAY SUMMARY: This study aimed to examine the variable language profiles in children with ASD. Children with ASD were shown to have impairments in the structure, meaning, and social use of language. These challenges were captured best by a measure that was created to assess the spontaneous use of language in a naturalistic environment. The results of this study emphasize the importance of a comprehensive assessment of language in ASD to inform treatment.

Titre : Subcategories of Restricted and Repetitive Behaviors in Children with Autism Spectrum Disorders Type de document : Texte imprimé et/ou numérique Auteurs : Somer L. BISHOP, Auteur ; Vanessa HUS, Auteur ; Amie W. DUNCAN, Auteur ; Marisela HUERTA, Auteur ; Katherine GOTHAM, Auteur ; Andrew PICKLES, Auteur ; Abba KREIGER, Auteur ; Andreas BUJA, Auteur ; Sabata LUND, Auteur ; Catherine LORD, Auteur Article en page(s) : p.1287-1297 Langues : Anglais (eng) Mots-clés : Autism spectrum disorders Repetitive behaviors Subcategories Repetitive sensory motor Insistence on sameness Index. décimale : PER Périodiques Résumé : Research suggests that restricted and repetitive behaviors (RRBs) can be subdivided into Repetitive Sensory Motor (RSM) and Insistence on Sameness (IS) behaviors. However, because the majority of previous studies have used the Autism Diagnostic Interview-Revised (ADI-R), it is not clear whether these subcategories reflect the actual organization of RRBs in ASD. Using data from the Simons Simplex Collection (n = 1,825), we examined the association between scores on the ADI-R and the Repetitive Behavior Scale-Revised. Analyses supported the construct validity of RSM and IS subcategories. As in previous studies, IS behaviors showed no relationship with IQ. These findings support the continued use of RRB subcategories, particularly IS behaviors, as a means of creating more behaviorally homogeneous subgroups of children with ASD.

Titre : Subdimensions of social-communication impairment in autism spectrum disorder Type de document : Texte imprimé et/ou numérique Auteurs : Somer L. BISHOP, Auteur ; Karoline Alexandra HAVDAHL, Auteur ; Marisela HUERTA, Auteur ; Catherine LORD, Auteur Article en page(s) : p.909-916 Langues : Anglais (eng) Mots-clés : Autism severity Autism Diagnostic Observation Schedule measurement basic social communication Interaction Quality Index. décimale : PER Périodiques Résumé : Background More refined dimensions of social-communication impairment are needed to elucidate the clinical and biological boundaries of autism spectrum disorders (ASD) and other childhood onset psychiatric disorders associated with social difficulties, as well as to facilitate investigations in treatment and long-term outcomes of these disorders. Methods This study was intended to identify separable dimensions of clinician-observed social-communication impairments by examining scores on a widely used autism diagnostic instrument. Participants included verbally fluent children ages 3–13 years, who were given a clinical diagnosis of ASD (n = 120) or non-ASD (i.e. ADHD, language disorder, intellectual disability, mood or anxiety disorder; n = 118) following a comprehensive diagnostic assessment. Exploratory and confirmatory factor analysis examined the factor structure of algorithm items from the Autism Diagnostic Observation Schedule (ADOS), Module 3. Results Results indicated that a three-factor model consisting of repetitive behaviors and two separate social-communication behavior factors had superior fit compared to a two-factor model that included repetitive behaviors and one social-communication behavior factor. In the three-factor model, impairments in ‘Basic Social-Communication’ behaviors (e.g. eye contact, facial expressions, gestures) were separated from impairments in ‘Interaction quality.’ Confirmatory factor analysis in an independent sample of children in the Simons Simplex Collection (SSC) further supported the division of social-communication impairments into these two factors. Scores in Interaction Quality were significantly associated with nonverbal IQ and male sex in the ASD group, and with age in the non-ASD group, while scores in basic social communication were not significantly associated with any of these child characteristics in either diagnostic group. Conclusions Efforts to conceptualize level, or severity, of social-communication impairment in children with neurodevelopmental disorders might be facilitated by separating the most basic (or proximal) social-communication impairments from those that could arise from a range of other phenotypic variables. Identification of social-communication subdimensions also highlights potential avenues for measuring different types of social-communication impairments for different purposes (e.g. for differential diagnosis vs. response to treatment).

Two-thirds of those surveyed reported some type of distress related to the pandemic (i.e. difficulty coping or negative impact on emotional and mental health). While there were no changes in depressive and anxiety symptoms from prior to COVID-19 to 10?week later in the group as a whole, self-reported distress predicted increases in both anxiety and depression across the two timepoints. Furthermore, adults with higher levels of anxiety prior to the pandemic were more likely to report distress, and women were more likely to report a negative impact of the pandemic on their emotional and mental health. Findings highlight the importance of monitoring with adults with autism spectrum disorder to assess their need for mental health support, and providing ongoing support to those who already experience anxiety even before the pandemic.
