Language Performance in Preschool-Aged Boys with Nonsyndromic Autism Spectrum Disorder or Fragile X Syndrome / Angela John THURMAN in Journal of Autism and Developmental Disorders, 50-5 (May 2020)
[article]
Titre : Language Performance in Preschool-Aged Boys with Nonsyndromic Autism Spectrum Disorder or Fragile X Syndrome Type de document : Texte imprimé et/ou numérique Auteurs : Angela John THURMAN, Auteur ; Cesar HOYOS ALVAREZ, Auteur Article en page(s) : p.1621-1638 Langues : Anglais (eng) Mots-clés : Autism spectrum disorder Fragile X syndrome Language/communication Index. décimale : PER Périodiques Résumé : In the present study, language performance on standardized assessments (e.g., overall verbal performance, receptive and expressive vocabulary) and spontaneous language produced in play was compared between preschool-aged boys with autism spectrum disorder (nASD, n = 25) and boys with fragile X syndrome (FXS, n = 16). At the group-level, we observed weaknesses in the language skills of boys with nASD relative to those with FXS (e.g., when considering raw score performance, standard score performance relative to nonverbal cognitive skills, frequency of talk in play), after controlling for nonverbal IQ and ASD symptom severity. Moreover, although individually most children in both groups demonstrated language delays relative to CA-expectations, language delays relative to nonverbal level-expectations were more common in boys with nASD.

Titre : Using weighted communication scoring procedures in naturalistic play samples: Preliminary validation in preschool-aged boys with autism or fragile X syndrome Type de document : Texte imprimé et/ou numérique Auteurs : Angela JOHN THURMAN, Auteur ; Cesar HOYOS ALVAREZ, Auteur ; Vivian NGUYEN, Auteur Article en page(s) : p.1755-1767 Langues : Anglais (eng) Mots-clés : Autism Spectrum Disorder Autistic Disorder Child Child, Preschool Communication Fragile X Syndrome Humans Male Reproducibility of Results autism fragile X syndrome naturalistic outcome measure weighting communication scores Index. décimale : PER Périodiques Résumé : In the present study, we provide a preliminary evaluation of the validity and reliability of using weighting procedures to measure communication in play samples for preschool-aged boys with autism or fragile X syndrome (FXS). Because weighting procedure communication scores (WPCSs) reflect growth in both communicative frequency and complexity, establishing the psychometrics of the component scores, in addition to the overall metric, affords investigators the opportunity to describe growth within and across skills. Results, for both groups, provide support regarding the psychometric appropriateness (i.e., convergent validity, divergent validity, and internal consistency) for all WPCSs. That said, a trend was observed for reliability scores to be slightly lower or more variable in boys with autism than in boys with FXS. Finally, although significant associations were observed in the associations between WPCSs across play contexts, contexts effects were observed for all three WPCSs. Together, results from this study provide promising preliminary data indicating the utility of using WPCSs in children with neurodevelopmental disabilities. Lay Summary: Language supports long-term positive outcomes; it is important to identify accurate and flexible ways of measuring language in children over time. We considered the effectiveness of using a procedure that considers changes in the number of communication acts and the types of acts produced during a play session by preschool-aged boys with autism or fragile X syndrome. These procedures were found to be valid and reliable. En ligne : http://dx.doi.org/10.1002/aur.2724 Permalink : https://www.cra-rhone-alpes.org/cid/opac_css/index.php?lvl=notice_display&id=483
