In a cohort of kindergarten children in Ontario, Canada with Autism Spectrum Disorder (ASD) (n = 1522), we tested the association of age at ASD diagnosis and characteristics of (1) the child's primary care provider and, (2) the child using health administrative databases. We tested the association of primary care practice model and time from…

Paraprofessionals are critical members of instructional teams for students with autism; however, little is known about their job preparation and professional development needs. This study addressed the gap in the literature by surveying 325 paraprofessionals in public school settings in the United States and Guam who reported working with students…

Children begin to show preferences for specific playmates as early as the first 2?years of life. Children with autism spectrum disorder have difficulty making friends, even in elementary and middle school. However, very little is known about earlier friendships in children with autism such as preschool friendships. This study examined friendships…

Difficulty with social competence is a core deficit of autism spectrum disorder. Research on typically developing children and children with disabilities, in general, suggests the adult talk received in the classroom is related to their social development. The aims of this study were to examine (1) the types and amounts of adult talk children with…

Peer interaction can be challenging in autism spectrum disorder, but naturalistic peer-observation scales for preschoolers are scarce. This study examined psychometric qualities of the newly developed Autism Peer Interaction Observation Scale. We tested the Autism Peer Interaction Observation Scale to (a) characterize peer interactions of…

We read 48 children's books featuring characters with autism spectrum disorder (ASD) to determine which books would be appropriate for use during read-alouds in early childhood classrooms. We conducted a search on Amazon for children's books on ASD published after 2010 and identified 50 books that met the following criteria: (a) the book was a…

This study examined the extent to which clinical and demographic characteristics predicted outcome for children with autism spectrum disorder. Participants included 152 students with autism spectrum disorder in 53 kindergarten-through-second-grade autism support classrooms in a large urban public school district. Associations between child…

Children with autism spectrum disorder (ASD) tend to be less playful than their typically developing (TD) peers. Although playfulness is considered a personality characteristic, little is known about the stability of this trait in interactions with different caregivers. This study compared the playfulness of children with and without ASD in play…

This study describes the language environment of preschool programs serving children with autism spectrum disorders (ASDs) and examines relationships between child characteristics and an automated measure of adult and child language in the classroom. The Language Environment Analysis (LENA) system was used with 40 children with ASD to collect data…

Autism spectrum disorders (ASD) are associated with many different levels of language and social impairment, differences in levels of cognitive impairment, varying levels of aberrant behavior, and discrepancies in the presence or amount of restrictive and repetitive behavior. The heterogeneity found within the ASD population is coupled with…

State early intervention programs (EIPs) have been encouraged to develop and implement comprehensive outcomes measurement systems. As the number of children with autism spectrum disorders (ASD) and their families receiving services in state EIPs increases, disability-specific outcomes data are needed to better understand issues of access, costs,…

Little is known about how special education services received by students with Autism Spectrum Disorders (ASDs) differ by age, disability severity, and demographic characteristics. Using three national data sets, the Pre-Elementary Education Longitudinal Study, the Special Education Elementary Longitudinal Study, and the National Longitudinal…

Current clinical diagnosis of Autism Spectrum Disorders (ASD) occurs between 3 and 4 years of age, but increasing evidence indicates that intervention begun earlier may improve outcomes. Using secondary analysis of the Early Childhood Longitudinal Study-Birth Cohort data set, the current study identifies early predictors prior to the diagnosis of…

Little is known about how special education services received by students with Autism Spectrum Disorders (ASDs) differ by age, disability severity, and demographic characteristics. Using three national datasets, the Pre-Elementary Education Longitudinal Study (PEELS), the Special Education Elementary Longitudinal Study (SEELS), and the National…
