Titre : Do non-referred young people with Autism Spectrum Disorders and their caregivers agree when reporting anxiety symptoms? A preliminary investigation using the Spence Children's Anxiety Scale Type de document : Texte imprimé et/ou numérique Auteurs : Iliana MAGIATI, Auteur ; Jing Yi CHAN, Auteur ; Wen-Li Julianne TAN, Auteur ; Kenneth K. POON, Auteur Article en page(s) : p.546-558 Mots-clés : Autism Anxiety Assessment Screening Agreement Reliability Index. décimale : PER Périodiques Résumé : Anxiety difficulties and disorders are common in children and youth people with Autism Spectrum Disorders (ASD), but only a few studies have specifically examined informant agreement in non-referred samples. The present study examined informant agreement between 38 Singaporean caregiver–child dyads using the Spence Children's Anxiety Scale Parent Version (SCAS-P) and the SCAS Child self-report (SCAS-C) respectively. The young people with ASD (mean age 12 years 10 months) completed the SCAS-C, while their caregivers completed the SCAS-P, the Scales of Independent Behavior-Revised and the Developmental Behavior Checklist. There was overall moderately good agreement between caregivers and children's reporting of anxiety symptoms. Intra-class correlations were highest in the Separation Anxiety, Generalized Anxiety and Physical Injury subscales. Fourteen of the 38 SCAS items, most of which described overt anxiety symptoms, showed strong or moderate inter-rater agreement. Higher severity of autism symptoms was associated with poorer agreement in the Generalized Anxiety, Panic and Obsessions/Compulsions SCAS subscales. These preliminary findings suggest that the SCAS may be a useful measure for reporting anxiety symptoms in terms of satisfactory agreement between caregivers and young people in non-referred settings. Implications for screening for anxiety in non-referred young people with ASD are also discussed.

Titre : Parental perspectives on the importance and likelihood of adult outcomes for children with Autism Spectrum Disorders, Intellectual Disabilities or Multiple Disabilities Type de document : Texte imprimé et/ou numérique Auteurs : Kenneth K. POON, Auteur ; Lynette KOH, Auteur ; Iliana MAGIATI, Auteur Article en page(s) : p.382-390 Langues : Anglais (eng) Mots-clés : Autism Spectrum Disorders Intellectual Disability Multiple Disability Parental expectations Importance Likelihood Adult outcomes Index. décimale : PER Périodiques Résumé : Aims This study examined parental perspectives on the importance and likelihood of future adult outcomes for children with Autism Spectrum Disorders (ASD), Intellectual Disabilities (ID), or Multiple Disabilities (MD) and some of the factors that may affect parental aspirations. Methods Parents of 105 children with ASD, ID, or MD were presented with 21 possible future outcomes and were asked to indicate how important and how likely they considered these outcomes for their children with disabilities when they become adults. Results Parents rated the overall likelihood of their child attaining various future outcomes significantly lower than the importance they placed on these same outcomes. They mostly valued future outcomes relating to their children's personal satisfaction, safety and security over and above those relating to social participation. Parental ratings of the importance or likelihood of outcomes did not differ across the diagnostic groups. Ratings of importance were independent of the child's age, gender, diagnosis, or severity of functioning, but likelihood ratings were significantly predicted by the children's symptom severity. Conclusions The implications of this study's findings for service development, intervention and transitioning planning, and treatment outcome research are discussed in relation to existing literature and the study's strengths and limitations.

Titre : The perception of social situations by children with autism spectrum disorders Type de document : Texte imprimé et/ou numérique Auteurs : Yong-Hwee NAH, Auteur ; Kenneth K. POON, Auteur Année de publication : 2011 Article en page(s) : p.185-203 Langues : Anglais (eng) Index. décimale : PER Périodiques Résumé : This study investigated how children with autism spectrum disorders (ASD) make social judgments of social situations and provide justifications for their responses. Fifteen children with ASD and 15 typically developing children (ages from 9 to 13 years old) were presented with eight vignettes, based on the Dewey Story Test (Dewey, 1991) and developed for the purposes of this study. The participants rated the appropriateness (on a 4-point Likert scale) of the socially inappropriate event (test item) and non-social appropriate event (control item) in each vignette. Justifications for each rating were also elicited at the end of each vignette. The children with ASD rated socially inappropriate behaviors in vignettes no differently from their typically developing peers but rated control items as stranger. They also had a higher tendency to provide inappropriate/bizarre and don’t know/no response justifications instead of appropriate/social justifications (that reflect social awareness). The impact of the method of eliciting social judgments of social situations and its impact on findings are discussed.

Titre : To What Extent Do Joint Attention, Imitation, and Object Play Behaviors in Infancy Predict Later Communication and Intellectual Functioning in ASD? Type de document : Texte imprimé et/ou numérique Auteurs : Kenneth K. POON, Auteur ; Linda R. WATSON, Auteur ; Grace T. BARANEK, Auteur ; Michele D. POE, Auteur Année de publication : 2012 Article en page(s) : p.1064-1074 Langues : Anglais (eng) Mots-clés : Infant Autism spectrum disorders Joint attention Imitation Object play Retrospective video analysis Index. décimale : PER Périodiques Résumé : The extent to which early social communication behaviors predict later communication and intellectual outcomes was investigated via retrospective video analysis. Joint attention, imitation, and complex object play behaviors were coded from edited home videos featuring scenes of 29 children with ASD at 9–12 and/or 15–18 months. A quantitative interval recording of behavior and a qualitative rating of the developmental level were applied. Social communication behaviors increased between 9–12 and 15–18 months. Their mean level during infancy, but not the rate of change, predicted both Vineland Communication scores and intellectual functioning at 3–7 years. The two methods of measurement yielded similar results. Thus, early social communicative behaviors may play pivotal roles in the development of subsequent communication and intellectual functioning.
