The prevalence of autism spectrum disorder in the world has increased over the last decade, but the prevalence, incidence, and characteristics of autism spectrum disorder in China were not well understood. Using administrative data, we aimed to estimate the prevalence and incidence of autism spectrum disorder and describe the co-occurring…

Accurate representation of autism spectrum disorder (ASD) in fragile X syndrome (FXS) is necessary for the field. We examined classifications of ASD using three approaches--Autism Diagnostic Observation Schedule (ADOS-2; Lord et al. 2012), Childhood Autism Rating Scale (CARS2-ST; Schopler et al. 2010), and Vineland Adaptive Behavior Scales…

Objectives: To examine and analyse the intervention effects of the Early Start Denver Model (ESDM) on children with autism spectrum disorder (ASD). Objectives: Methods: This meta-analysis evaluated the effect sizes in four major domains of measurement (autism symptoms, language, cognition, and social communication). A total of 624 participants…

One of the earliest indicators of autism spectrum disorder (ASD) is delay in language and social communication. Despite consensus on the benefits of earlier diagnosis and intervention, our understanding of the language growth of children with ASD during the first years of life remains limited. Therefore, this study compared communication growth…

Autism spectrum disorder symptom emergence is heterogeneous, yet literature comparing young children diagnosed early versus later is relatively scant. Toddlers diagnosed with autism spectrum disorder between 12 and 18 months (n = 20), 19 and 24 months (n = 65), or 25 and 41 months (n = 27) were compared on demographics, developmental functioning,…

In the current study, we investigated the effects of an instructional package (i.e., response prompting, sentence frames) on sentence writing for three middle school participants (ages 12-13) with moderate to severe disabilities. We employed a multiple probe across behaviors design to evaluate the efficacy of the intervention package and also used…

Students with an autism spectrum disorder (ASD) are being educated in general education content classrooms that use lessons directed to whole groups of students which limit use of visually presented material. For some students with ASD, having limited visual support hinders their abilities to process and comprehend material. Research shows…

School psychologists play a critical role in school-based Autism (AU) evaluations. Evidence-based AU evaluations should be multimodal, include multiple informants, and assess functioning across several domains. In the current era of COVID-19, school-based AU evaluations have become increasingly complex with school psychologists having to…

The administration requirements of the Autism Diagnostic Observation Schedule and the Autism Diagnostic Interview-Revised, widely used in high-income countries, make them less feasible for diagnosis of autism spectrum disorder in low- and middle-income countries. The flexible administration requirements of the Childhood Autism Rating Scale have…

Atypical sensory response patterns are common in children with autism and developmental delay. Expanding on previous work, this observational electroencephalogram study assessed auditory event-related potentials and their associations with clinically evaluated sensory response patterns in children with autism spectrum disorder (n = 28),…

Differences in behavioral and cognitive profiles have been suggested to potentially impact the presentation of social and communication symptoms in females with autism spectrum disorder. This study examined gender differences in age of diagnosis, cognitive profiles, social communication symptomatology, and autism spectrum disorder symptom severity…

The purpose of this study was to pilot test the effects of a culturally adapted early intervention influenced by the Early Start Denver Model (ESDM) on reduction of autism symptoms and severity categorization for young children with autism spectrum disorders in China. Participants were randomly assigned to either the control or intervention…

Given that early caregiver concerns may be different for children who go on to receive a diagnosis of autism spectrum disorder versus another developmental disability, early caregiver concerns may differ for girls. Using a community-based sample of children (n = 241), we examined the extent to which gender differences may be related to caregiver…

Introduction: Records-based autism spectrum disorder surveillance developed at the Centers for Disease Control and Prevention has been extended to younger cohorts, although the utility of additional record sources has not been examined. We therefore conducted a pilot project to describe whether Centers for Disease Control and Prevention…

This study investigated questions adults asked to children with autism spectrum disorder in inclusive pre-kindergarten classrooms, and whether child (e.g. autism severity) and setting (i.e. adult-to-child ratio) characteristics were related to questions asked during center-time. Videos of verbal children with autism spectrum disorder (n?=?42) were…
