Standardizing ADOS Domain Scores: Separating Severity of Social Affect and Restricted and Repetitive Behaviors / Vanessa HUS in Journal of Autism and Developmental Disorders, 44-10 (October 2014)
[article]
Titre : Standardizing ADOS Domain Scores: Separating Severity of Social Affect and Restricted and Repetitive Behaviors Type de document : Texte imprimé et/ou numérique Auteurs : Vanessa HUS, Auteur ; Katherine GOTHAM, Auteur ; Catherine LORD, Auteur Article en page(s) : p.2400-2412 Langues : Anglais (eng) Mots-clés : Autism spectrum disorders Autism Diagnostic Observation Schedule Severity Social Affect Restricted and Repetitive Behaviors Index. décimale : PER Périodiques Résumé : Standardized Autism Diagnostic Observation Schedule (ADOS) scores provide a measure of autism severity that is less influenced by child characteristics than raw totals (Gotham et al. in Journal of Autism and Developmental Disorders, 39(5), 693–705 2009). However, these scores combine symptoms from the Social Affect (SA) and Restricted and Repetitive Behaviors (RRB) domains. Separate calibrations of each domain would provide a clearer picture of ASD dimensions. The current study separately calibrated raw totals from the ADOS SA and RRB domains. Standardized domain scores were less influenced by child characteristics than raw domain totals, thereby increasing their utility as indicators of Social-Communication and Repetitive Behavior severity. Calibrated domain scores should facilitate efforts to examine trajectories of ASD symptoms and links between neurobiological and behavioral dimensions.

Titre : Standardizing ADOS Scores for a Measure of Severity in Autism Spectrum Disorders Type de document : Texte imprimé et/ou numérique Auteurs : Katherine GOTHAM, Auteur ; Catherine LORD, Auteur ; Andrew PICKLES, Auteur Année de publication : 2009 Article en page(s) : p.693-705 Langues : Anglais (eng) Mots-clés : Autism-spectrum-disorders Autism-diagnostic-observation-schedule-(ADOS) Severity Index. décimale : PER Périodiques Résumé : The aim of this study is to standardize Autism Diagnostic Observation Schedule (ADOS) scores within a large sample to approximate an autism severity metric. Using a dataset of 1,415 individuals aged 2–16 years with autism spectrum disorders (ASD) or nonspectrum diagnoses, a subset of 1,807 assessments from 1,118 individuals with ASD were divided into narrow age and language cells. Within each cell, severity scores were based on percentiles of raw totals corresponding to each ADOS diagnostic classification. Calibrated severity scores had more uniform distributions across developmental groups and were less influenced by participant demographics than raw totals. This metric should be useful in comparing assessments across modules and time, and identifying trajectories of autism severity for clinical, genetic, and neurobiological research.

Several research groups have initiated prospective studies of high-risk populations including infant siblings, to systematically collect data on early signs within a longitudinal design. Despite the potential advantages of prospective studies of young children at high-risk for autism, there are also significant methodological, ethical and practical challenges. This paper outlines several of these challenges, including those related to sampling (e.g., defining appropriate comparison groups), measurement and clinical implications (e.g., addressing the needs of infants suspected of having early signs). We suggest possible design and implementation strategies to address these various challenges, based on current research efforts in the field and previous studies involving high-risk populations.

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).
