Purpose: Telemedicine approaches to autism (ASD) assessment have become increasingly common, yet few validated tools exist for this purpose. This study presents results from a clinical trial investigating two approaches to tele-assessment for ASD in toddlers. Methods: 144 children (29% female) between 17 and 36 months of age (mean = 2.5 years, SD…

The smallest subset of items from the 30-item Checklist for Autism Spectrum Disorder (CASD) that differentiated 607 referred children (3-17 years) with and without autism with 100% accuracy was identified. This 6-item subset (CASD-Short Form) was cross-validated on an independent sample of 397 referred children (1-18 years) with and without autism…

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…

The systematic use of reinforcers is an essential component of behavioral intervention for individuals diagnosed with Autism Spectrum Disorder. Today, the use of rigorous formal preference assessments, including paired-preference assessments, are widely conducted to help determine which items to use as reinforcers during intervention. Although…

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…

Analogical reasoning is an important mechanism for social cognition in typically developing children, and recent evidence suggests that some forms of analogical reasoning may be preserved in autism spectrum disorder. An unanswered question is whether children with autism spectrum disorder can apply analogical reasoning to social information. In…

This study examines whether explicit reading comprehension instruction is relevant for students with high-functioning autism spectrum disorder (ASD). Forty-five students (M[subscript age] = 9 years) were randomly assigned to two conditions: control or intervention. Those assigned to the intervention condition received instruction on vocabulary,…

Children with autism spectrum disorder present with a variety of social communication deficits such as atypicalities in social gaze and verbal and non-verbal communication delays as well as perceptuo-motor deficits like motor incoordination and dyspraxia. In this study, we had the unique opportunity to study praxis performance in deaf children…

The purpose of the study was to evaluate the use of the iPod Touch™ as a Speech Generated Device (SGD) for Functional Communication Training (FCT). The evaluation of the effects on problem behavior, the effects on generalization and maintenance of the acquired communication repertoire, and the social initiations of peers between the new SGD (iPod…

This research addresses the challenges of assessing receptive language abilities in minimally verbal children with autism spectrum disorder by comparing several adapted measurement tools: a standardized direct assessment of receptive vocabulary (i.e. Peabody Picture Vocabulary Test-4); caregiver report measures including scores on the Vineland-II…

In order to examine the roles of mental age, social interaction, and communication in self-representation abilities, typically-developing children were compared with children with Autism Spectrum Disorders. Typically-developing children (TD, n = 66) and children with Autism Spectrum Disorders (ASD, n = 20), including subgroups of autistic disorder…

This randomized field trial comparing Strategies for Teaching based on Autism Research and Structured Teaching enrolled educators in 33 kindergarten-through-second-grade autism support classrooms and 119 students, aged 5-8 years in the School District of Philadelphia. Students were assessed at the beginning and end of the academic year using the…

The validity of the calibrated severity scores on the ADOS as reported by Gotham et al. (J Autism Dev Disord 39: 693-705, "2009"), was investigated in an independent sample of 1248 Dutch children with 1455 ADOS administrations (modules 1, 2 and 3). The greater comparability between ADOS administrations at different times, ages and in…

Background: Studies of chromosome 15 abnormality have implicated over-expression of paternally imprinted genes in the 15q11-13 region in the aetiology of autism. To test this hypothesis we compared individuals with Prader-Willi syndrome (PWS) due to uniparental disomy (UPD--where paternally imprinted genes are over-expressed) to individuals with…
