This meta-analysis synthesizes gains in communication and relative lack of gains made in speech across the PECS literature for children with ASD. Concerns about maintenance and generalization are identified. Emerging evidence of potential preintervention child characteristics is discussed. Phase IV was identified as a possibly influential program characteristic for speech outcomes.
One way to support the social engagement of children with autism spectrum disorders (ASD) is by identifying features of natural environments that increase the likelihood of social interaction. This descriptive study was an examination of the (a) social engagement of 68 preschoolers with ASD in classrooms, (b) ecological features of classrooms that promoted social engagement, and (c) relationships between social engagement and ecological features using the Code for Active Student Participation and Engagement-Revised, an ecobehavioral observational system. Overall, children without ASD were most likely to be socially engaged with peers in the Books and Food/Snack classroom areas, when participating in book or large motor behaviors, in small groups with peers or large groups with an adult, and during child-initiated activities. Implications for practice and future research are highlighted.
The advancing social-communication and play (ASAP) intervention was designed as a classroom-based intervention, in which the educational teams serving preschool-aged children with autism spectrum disorder are trained to implement the intervention in order to improve these children's social-communication and play skills. In this 4-year, multi-site efficacy trial, classrooms were randomly assigned to ASAP or a business-as-usual control condition. A total of 78 classrooms, including 161 children, enrolled in this study. No significant group differences were found for the primary outcomes of children's social-communication and play. However, children in the ASAP group showed increased classroom engagement. Additionally, participation in ASAP seemed to have a protective effect for one indicator of teacher burnout. Implications for future research are discussed.
The purpose of this study was to examine the psychometric properties of the Autism Program Environment Rating Scale (APERS), an instrument designed to assess quality of program environments for students with autism spectrum disorder. Data sets from two samples of public school programs that provided services to children and youth with autism spectrum disorder were utilized. Cronbach alpha analyses indicated high coefficients of internal consistency for the total APERS and moderate levels for item domains for the first data set, which was replicated with the second data set. A factor analysis of the first data set indicated that all domain scores loaded on one main factor, in alignment with the conceptual model, with this finding being replicated in the second data set. Also, the APERS was sensitive to changes resulting from a professional development program designed to promote program quality.
The autism spectrum disorder (ASD) diagnostic classifications, according to the DSM-5, include a severity rating. Several screening and/or diagnostic measures, such as the autism diagnostic and observation schedule (ADOS), Childhood Autism Rating Scale (CARS) and social responsiveness scale (SRS) (teacher and parent versions), include an assessment of symptom severity. The purpose of this study was to examine whether symptom severity and/or diagnostic status of preschool-aged children with ASD (N = 201) were similarly categorized on these measures. For half of the sample, children were similarly classified across the four measures, and scores on most measures were correlated, with the exception of the ADOS and SRS-P. While the ADOS, CARS, and SRS are reliable and valid measures, there is some disagreement between measures with regard to child classification and the categorization of autism symptom severity.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
