Autism spectrum disorders are diagnosed globally, but recognition, interpretation and reporting may vary across cultures. To compare autism across cultures it is important to investigate whether the tools used are conceptually equivalent across cultures. This study evaluated the factor structure of the parent-reported Autism Spectrum Quotient…

The necessity of promoting physical activity in individuals with Autism Spectrum Disorder (ASD) has been emphasized for decades. One of the barriers to participate in physical activity for individuals with ASD is limited interest and motivation. Therefore, understanding the motivation to exercise in this population is important. The objective was…

This study examines the types of interactions and early literacy development that occur when non-verbal 4-year-old children on the autism spectrum engage with family members in read-alouds using authentic children's literature. Findings indicate the importance of quality children's literature for read-alouds. A key implication of the study is that…

The aim of the study was to perform family-based association analysis of "PRKCB1," "CBLN1" and "KCNMB4" gene polymorphisms and autism disorder. We comprised 206 Caucasian children with autistic spectrum disorder (ASD) and their biological parents. In transmission/disequilibrium test we observed that T-allele of the…

Little is known about the development of self-regulation processes during the preschool period in autism spectrum disorder (ASD). How parental characteristics such as the broader autism phenotype (BAP) relate to children's self-regulation is not well understood. Preschool-aged children with (n = 24) and without ASD (n = 21) completed an inhibitory…

To efficiently learn new words, children use constraints such as mutual exclusivity (ME) to narrow the search for potential referents. The current study investigated the use of ME in toddlers with autism spectrum disorder (ASD) and neurotypical (NT) peers matched on nonverbal cognition. Thirty-two toddlers with ASD and 26 NT toddlers participated…

Purpose: Pitch plays an important role in auditory perception of music and language. This study provides a systematic review with meta-analysis to investigate whether individuals with autism spectrum disorder (ASD) have enhanced pitch processing ability and to identify the potential factors associated with processing differences between ASD and…

The study evaluated the convergent validity of the PEAK-E-PA and two common assessments of language development used in educational and clinical settings: the ABLLS-R and the TOLD-I:4. The PEAK-E-PA provides a measure of a participant's ability to derive arbitrary stimulus relations, and may therefore provide a more complex analysis of language…

Little is known about the impact of testing modality on math performance, particularly for students with autism spectrum disorder (ASD). In the current study, a multielement, single-case design was used with three students with ASD across three math fluency assessment modalities: paper-pencil, iPad with a stylus, and iPad with a keyboard. Each…

Children with autism spectrum disorder (ASD) have communication deficits that lead to difficulties in expressing their needs and establishing relationships with others. Parent-mediated intervention is a method to improve communication skills of children with ASD. The purpose of this study was to evaluate the effects of parent-mediated multimodal…

Research has documented inequities in geographic access to Board Certified Behavior Analysts (BCBAs) among children with autism spectrum disorder (ASD). However, research on their accessibility is outdated. Between July 1, 2018 and July 1, 2021 the number of BCBAs in the U.S. increased by 65%, from 27,320 to 45,103. In this study we examined…

PEERS® for Adolescents is an evidence-based social skills intervention for autistic youth and adolescents with other social challenges. The efficacy and effectiveness of PEERS® are well established; however, limited data on PEERS® via telehealth delivery exist. The current study aimed to examine the efficacy of PEERS® for Adolescents via…

The causes of aggressive behavior in children with autism are poorly understood, which limits treatment options. Therefore, this study used behavioral testing and parent reports of 60 children with autism to investigate the interplay of emotion misinterpretation and hostile attribution bias in the prediction of different aggressive behaviors.…

Perceived personal wellbeing tends to be lower in individuals with autism spectrum disorders (ASD), especially in the case of women. To develop the present study, the Personal Wellbeing Index (PWI-A) was administered to a Spanish-speaking sample of women with ASD (N = 401) and self-diagnosed ASD (N = 343), women without ASD (N = 373) and men with…

Autism is diagnosed based on social and communication difficulties, restricted and repetitive behaviours and sensory anomalies. Existing evidence indicates that anxiety and atypical sensory features are associated with restricted and repetitive behaviours, but cannot clarify the order of emergence of these traits. This study uses data from a…
