Public ISBD [article]  inAutism Research > 13-5 (May 2020) . - p.796-809 Titre : Exploring Developmental and Behavioral Heterogeneity among Preschoolers with ASD: A Cluster Analysis on Principal Components Type de document : Texte imprimé et/ou numérique Auteurs : Shuting ZHENG, Auteur ; Kara A. HUME, Auteur ; Harriet ABLE, Auteur ; Somer L. BISHOP, Auteur ; Brian A.

The identification of subgroups within a specific age range could be useful for understanding prognosis and treatment planning. We applied Hierarchical Clustering on Principal Components (HCPC) with a sample of 188 preschoolers with ASD and identified three distinct subgroups based on multiple developmental and behavioral domains. Cluster 1 was characterized by relatively high cognitive, language and adaptive abilities, and relatively low levels of social symptoms, repetitive behaviors, and sensory issues within the sample. Cluster 2 was characterized by similarly high cognitive, language and adaptive abilities compared to Cluster 1, but more severe social deficits as well as repetitive and sensory behaviors. Finally, Cluster 3 was characterized by lower cognitive, language and adaptive abilities, and more severe social, repetitive, and sensory symptoms. These findings provide insights into how considering multiple developmental and behavioral domains and core autism symptoms simultaneously can distinguish subgroups of young children with ASD and provide more comprehensive developmental profiles. Moreover, the unique profile of children in Cluster 2 highlighted the usefulness of including different measures and informants when evaluating the abilities and deficits of preschoolers with ASD and the importance of understanding the relationships among different developmental and behavioral factors in this specific population. Autism Res 2020, 13: 796-809. (c) 2020 International Society for Autism Research, Wiley Periodicals, Inc. LAY SUMMARY: Children with autism exhibit a range of abilities and deficits in different developmental and behavioral areas, making it difficult to tailor treatment and predict outcomes. We identified three distinct subgroups among 188 preschoolers with autism spectrum disorder distinguished by the combination of measures from multiple developmental and behavioral domains. The findings revealed the importance of comprehensive profiling of the child's abilities and deficits to inform subgrouping within autism.

Quality of high school programs for students with autism spectrum disorder / Bonnie R. KRAEMER in Autism, 24-3 (April 2020)  

Public ISBD [article]  inAutism > 24-3 (April 2020) . - p.707-717 Titre : Quality of high school programs for students with autism spectrum disorder Type de document : Texte imprimé et/ou numérique Auteurs : Bonnie R.

STEINBRENNER, Auteur ; Katherine SZIDON, Auteur ; Christopher BRUM, Auteur Article en page(s) : p.707-717 Langues : Anglais (eng) Mots-clés : autism spectrum disorders  high school  interventions-psychosocial/behavioral Index. décimale : PER Périodiques Résumé : The purpose of the study was to examine the quality of high school programs for students with autism spectrum disorder in the United States. The Autism Program Environment Rating Scale-Middle/High School was used to rate the quality of programs for students with autism spectrum disorder in 60 high schools located in three geographic locations in the United States (CA, NC, and WI). Findings indicated that the total quality rating across schools was slightly above the adequate criterion. Higher quality ratings occurred for program environment, learning climate, family participation, and teaming domains. However, quality ratings for intervention domains related to the characteristics of autism spectrum disorder (e.g. communication, social, independence, functional behavior, and transition) were below the adequate quality rating level. Also, quality ratings for transition were significantly higher for modified (primarily self-contained) programs than standard diploma (primarily served in general education) programs. School urbanicity was a significant predictor of program quality, with suburban schools having higher quality ratings than urban or rural schools, controlling for race, school enrollment size, and Title 1 eligibility status. Implications for working with teachers and school teams that support high school students with autism spectrum disorder should include a targeted focus on transition programming that includes a breadth of work-based learning experiences and activities that support social-communication domains.

Sex Differences in Social Participation of High School Students with Autism Spectrum Disorder / Leann S. DAWALT in Autism Research, 13-12 (December 2020)  

Public ISBD [article]  inAutism Research > 13-12 (December 2020) . - p.2155-2163 Titre : Sex Differences in Social Participation of High School Students with Autism Spectrum Disorder Type de document : Texte imprimé et/ou numérique Auteurs : Leann S. DAWALT, Auteur ; Julie LOUNDS TAYLOR, Auteur ; Somer L. BISHOP, Auteur ; Laura J. HALL, Auteur ; Jessica Dykstra STEINBRENNER, Auteur ; Bonnie KRAEMER, Auteur ; Kara A. HUME, Auteur ; Samuel L ODOM, Auteur Article en page(s) : p.2155-2163 Langues : Anglais (eng) Mots-clés : adolescence  autism spectrum disorder  sex differences  social interactions Index. décimale : PER Périodiques Résumé : There is lack of consensus in the literature regarding sex differences in social outcomes for individuals on the autism spectrum. Furthermore, little research has focused on the social experiences of high school students with autism spectrum disorder (ASD) during the school day. Using a large racially/ethnically diverse sample of high school students with ASD receiving special education services (n = 547; 76 females, 471 males), we examined sex differences in social interactions of youth both during and after school. We also tested for sex differences in background and phenotypic characteristics including autism severity, IQ, adaptive behavior, and mental health. Results indicated few statistically significant differences between males and females in social interactions and phenotypic characteristics (including raw scores of autism symptom severity). However, analysis of standardized scores of autism symptoms suggested that symptom scores for females with ASD diverged more from same-sex peers in the normed sample than scores of males with ASD. Lack of sex difference in social participation for youth with ASD in this study stands in contrast to patterns of sex differences in the general population. Findings suggest that few differences between males and females with ASD, both in social participation and autism symptom severity, might result in females with ASD being more dissimilar to their same-sex peers than males with ASD. Implications of findings for understanding sex differences in ASD across the life course are discussed. LAY SUMMARY: The present study examined sex differences in social participation in a large, diverse sample of high school students with autism spectrum disorder (ASD). Males and females were very similar in their social interactions both at school and outside of school, based on reports by teachers and parents. Level of autism symptoms was also similar for males and females. However, standardized scores of autism symptoms, which take into account age and sex specific norms, suggested that females with ASD may have behaviors that are more divergent from their same-sex peers than males with ASD.
