Though there is evidence autism identification has been inequitable for populations who are culturally and linguistically minoritized, there is limited research that explains the issue of disproportionality and factors contributing to its occurrence, especially within an educational setting. To explore contributors to racial/ethnic disparities in…

Although motor problems are highly prevalent in children with autism spectrum disorder (ASD), they remain underdiagnosed. Questionnaire-based screening for motor problems could optimize current clinical practice. This study aimed to examine the psychometric properties of the developmental coordination disorder questionnaire (DCDQ) to screen for…

Many autistic children access some form of early intervention, but little is known about the value for money of different programs. We completed a scoping review of full economic evaluations of early interventions for autistic children and/or their families. We identified nine studies and reviewed their methods and quality. Most studies involved…

Published healthcare cost estimates for children with autism spectrum disorder (ASD) vary widely. One possible contributor is different methods of case ascertainment. In this study, ASD case status was determined using two sources of parent reports among 45,944 children ages 3-17 years in the Medical Expenditure Panel Survey (MEPS) linked to the…

It is well-recognized that measurement options for diagnosing and monitoring children with neurogenetic syndromes (NGS) associated with moderate to severe intellectual impairment are limited (Berry-Kravis, Dev Med Child Neurol 10.1111/dmcn.13018, 2016), and caregivers experience significant concerns regarding the assessment process. However to…

The Autism Classification System of Functioning: Social Communication (ACSF) describes social communication functioning levels. First developed for preschoolers with ASD, this study tests an expanded age range (2-to-18 years). The ACFS rates the child's typical and best (i.e., capacity) performance. Qualitative methods tested parent and clinician…

The validity of joint attention assessment in school-aged children with ASD is unclear (Lord, Jones, "Journal of Child Psychology and Psychiatry" 53(5):490-509, 2012). This study examined the feasibility and validity of a parent-report measure of joint attention related behaviors in verbal children and adolescents with ASD. Fifty-two…

In the present work, we have undertaken a proof-of-concept study to determine whether a simple upper-limb movement could be useful to accurately classify low-functioning children with autism spectrum disorder (ASD) aged 2-4. To answer this question, we developed a supervised machine-learning method to correctly discriminate 15 preschool children…

Purpose: To determine the incidence of ophthalmologic disorders in children with autism and related disorders. Design: Retrospective chart review. Four hundred and seven children diagnosed with autism or a related disorder between 1998 and 2006. One hundred and fifty-four of these children completed a comprehensive ophthalmology exam by a…

The current study tested several competing models of the autism phenotype using data from modules 1 and 3 of the ADOS. Participants included individuals with ASDs aged 3-18 years (N = 1,409) from the AGRE database. Confirmatory factor analyses were performed on total samples and subsamples based on age and level of functioning. Three primary…

Asperger syndrome (AS) patients show heterogeneous intelligence profiles and the validity of short forms for estimating intelligence has rarely been studied in this population. We analyzed the validity of Wechsler Intelligence Scale (WIS) short forms for estimating full-scale intelligence quotient (FSIQ) and assessing intelligence profiles in 29…

The Social Responsiveness Scale (SRS) is a tool for quantitative autism assessment in children and adolescents. The SRS-A addresses social responsiveness in adulthood. Reliability and validity using the German adaptation of the SRS-A was examined in 20 adults with Autism Spectrum Disorder (ASD), 62 with other mental disorders (CLIN) and 163…

Hyperbaric oxygen therapy (HBOT) has been used to treat individuals with autism. However, few studies of its effectiveness have been completed. The current study examined the effects of 40 HBOT sessions at 24% oxygen at 1.3 ATA on 11 topographies of directly observed behavior. Five replications of multiple baselines were completed across a total…

This study tested the efficacy of a new social skills intervention, "S ocial S kills GR oup IN tervention-High Functioning Autism" ("S.S.GRIN-HFA"), designed to improve social behaviors in children with high functioning autism spectrum disorders. Fifty-five children were randomly assigned to "S.S.GRIN-HFA" treatment (n = 27) or control (i.e.,…

The behavioral phenotype of Williams syndrome (WS) is characterized by difficulties with establishment and maintenance of friendships despite high levels of interest in social interaction. Here, parents and teachers rated 84 children with WS ages 4-16 years using two commonly-used measures assessing aspects of social functioning: the Social Skills…
