Titre : Peabody Picture Vocabulary Test: Proxy for Verbal IQ in Genetic Studies of Autism Spectrum Disorder Type de document : Texte imprimé et/ou numérique Auteurs : Kate E. KRASILEVA, Auteur ; Stephan J. SANDERS, Auteur ; Vanessa H. BAL, Auteur Article en page(s) : p.1073-1085 Langues : Anglais (eng) Mots-clés : Autism spectrum disorder Intelligence tests Cognition Language tests Index. décimale : PER Périodiques Résumé : This study assessed the utility of a brief assessment (the Peabody Picture Vocabulary Test—4th Edition; PPVT4) as a proxy for verbal IQ (VIQ) in large-scale studies of autism spectrum disorder (ASD). In a sample of 2,420 proband with ASD, PPVT4:IQ correlations were strong. PPVT4 scores were, on average, 5.46 points higher than VIQ; 79% of children had PPVT4 scores within one standard deviation (+/?15) of their VIQ and 90% were similarly classified as having abilities above or below 70 on both measures. Distributions of PPVT4 and VIQ by de novo mutation status were highly similar. These results strongly support the utility of PPVT4 as a proxy for VIQ in large-scale ASD studies, particularly for genetic investigations.

Index. décimale : PER Périodiques Résumé : BACKGROUND: Studies estimate that 30% of individuals with autism are minimally verbal. Understanding what factors predict longer-term expressive development in children with language delays is critical to inform identification and treatment of those at-risk for persistent language impairments. The present study examined predictors of expressive language development in language-delayed preschoolers followed through later school-age and young adulthood. METHODS: Children using single words or less on the Autism Diagnostic Observation Schedule (ADOS) at approximately 3 years old were drawn from the Early Diagnosis (EDX) and Pathways in ASD longitudinal cohorts. Age-3 predictors of Age-19 ADOS language level were identified using Classification and Regression Trees (CART) in the EDX sample. Linear mixed models examined the effects of CART-identified predictors on Vineland expressive communication (VExp) trajectories from Age-3 to Age-19. The same linear mixed models were examined in the Pathways sample, identifying predictors of VExp from ages 3 to 10.5 years. RESULTS: Significantly delayed fine motor skills (T-score < 20) was the strongest CART predictor of Age-19 language. In the linear mixed models, time, Age-3 fine motor skills and initiation of joint attention (IJA) predicted VExp trajectories in the EDX sample, even when controlling for Age-3 visual receptive abilities. In the Pathways sample, time and Age-3 fine motor skills were significant predictors of VExp trajectories; IJA and cognitive skills were not significant predictors. CONCLUSIONS: Marked deficits in fine motor skills may be a salient proxy marker for identifying language-delayed children with ASD who are at risk for persistent language impairments. This finding adds to the literature demonstrating a relation between motor and language development in ASD. Investigating individual skill areas (e.g., fine motor and nonverbal problem-solving skills), rather than broader indices of developmental level (e.g., nonverbal IQ) may provide important cues to understanding longer-term language outcomes that can be targeted in early intervention.

This new algorithm, however, has not yet been validated in an independent sample without intellectual disability (ID). This multi-site study compared the original and revised algorithms in individuals with ASD without ID. The revised algorithm demonstrated increased sensitivity, but lower specificity in the overall sample. Estimates were highest for females, individuals with a verbal IQ below 85 or above 115, and ages 16 and older. Best practice diagnostic procedures should include the Module 4 in conjunction with other assessment tools. Balancing needs for sensitivity and specificity depending on the purpose of assessment (e.g., clinical vs. research) and demographic characteristics mentioned above will enhance its utility.

Titre : Replication of Standardized ADOS Domain Scores in the Simons Simplex Collection Type de document : Texte imprimé et/ou numérique Auteurs : Vanessa H. BAL, Auteur ; Catherine LORD, Auteur Article en page(s) : p.583-592 Langues : Anglais (eng) Mots-clés : autism spectrum disorder Autism Diagnostic Observation Schedule severity social affect restricted and repetitive behaviors Index. décimale : PER Périodiques Résumé : Raw totals from diagnostic and screening measures for autism spectrum disorder (ASD) are frequently used as dimensional measures of autism symptom severity without appropriate correction for confounding factors, such as developmental level or non-ASD-specific behavior problems. Although these associated features are important to consider when diagnosing ASD and developing intervention plans, both researchers and clinicians sometimes need metrics of ASD severity that are not influenced by these factors. The Autism Diagnostic Observation Schedule (ADOS) domain calibrated severity scores (CSS) were created to provide separate estimates of social affect (SA-CSS) and restricted, repetitive behaviors (RRB-CSS) that are relatively independent of child characteristics (Hus et al., 2014). Using a sample of 2,509 probands with ASD from the Simons Simplex Collection (SSC), this study provides the first replication of the ADOS domain CSS in an independent sample. Consistent with the original standardization study, when applied to existing SSC data, the ADOS domain CSS were less influenced by age and cognitive ability compared to raw domain totals. Domain CSS were also relatively independent of behavior problems. Use of the ADOS domain CSS to assess relationships between ASD symptoms and genetic risk factors will increase confidence that associations reflect domain-specific relationships. Scores also offer less developmentally-influenced estimates of ASD severity for future phenotypic explorations in the SSC. This independent replication provides support for the application of the ADOS domain CSS in other samples, though further replication in population-based samples will be an important next step.
