This study explores sex-differences in (a) rates and profiles of autism symptoms as well as in (b) the contribution of intellectual quotient (IQ) to autism symptom presentation in Down syndrome (DS). Participants were 40 males and 38 females with DS, aged 6 to 23 years. Autism symptoms were rated through the Autism Diagnostic Observation…

This study characterizes the subcortical auditory brainstem response (speech-ABR) and cortical auditory processing (P1 and Mismatch Negativity; MMN) to speech sounds and their relationship to autistic traits and sensory features within the same group of autistic children (n = 10) matched on age and non-verbal IQ to their typically developing (TD)…

Infants at elevated likelihood of developing autism display differences in sensory reactivity, especially hyporeactivity, as early as 7 months of age, potentially contributing to a developmental cascade of autism symptoms. Caregiver responsiveness, which has been linked to positive social communication outcomes, has not been adequately examined…

Rea, Hannah M.; Øien, Roald A.; Shic, Frederick; Webb, Sara Jane; Ratto, Allison B. – Journal of Autism and Developmental Disorders, 2023
The sex difference in the prevalence of autism spectrum disorder (ASD) may be magnified by sex differences on diagnostic measures. The current study compared autistic males and females on items on the gold-standard diagnostic measure, the Autism Diagnostic Observation Schedule, Second Edition (ADOS-2). In a sample of 8-to-17-year old autistic…

This study investigated sex and age differences in autistic behaviours in children with neurofibromatosis type 1 (NF1) who scored within the clinical range on the Social Responsiveness Scale - Second Edition (T score [greater than or equal to] 60). Thirty-four males and 28 females (3-16 years) were assessed with the Autism Diagnostic Observation…

The Autism Mental Status exam (AMSE) has demonstrated excellent sensitivity and specificity in Western high-risk population with suspected autism spectrum disorder (ASD). This study aimed to evaluate the psychometric properties of the AMSE in a sample of high-risk Chinese children, and to determine the optimal cutoff score of the Chinese version…

Liu, Fangyuan; Scheeren, Anke M.; Grove, Rachel; Hoekstra, Rosa A.; Wang, Ke; Guo, Dehua; Wang, Chongying; Begeer, Sander – Journal of Autism and Developmental Disorders, 2022
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…

Galligan, Megan Ledoux; Heyman, Michelle; Bolourian, Yasamin; Stavropoulos, Katherine; Blacher, Jan – Journal of Autism and Developmental Disorders, 2022
Emotional and behavioral problems (EBPs), such as anxiety, overactivity, and aggression, can influence the diagnosis of autism spectrum disorder (ASD). The gold standard diagnostic tool for ASD, the "Autism Diagnostic Observation Schedule--Second Edition," includes three items ("E-codes") for EBPs that are frequently associated…

Dow, Deanna; Holbrook, Alison; Toolan, Christina; McDonald, Nicole; Sterrett, Kyle; Rosen, Nicole; Kim, So Hyun; Lord, Catherine – Journal of Autism and Developmental Disorders, 2022
Interest in telehealth assessment for autism has increased due to COVID-19 and subsequent expansion of remote psychological services, though options that are easy for clinicians to adopt and available through the lifespan are limited. The Brief Observation of Symptoms of Autism (BOSA) provides a social context with standardized materials and…

Waizbard-Bartov, Einat; Ferrer, Emilio; Young, Gregory S.; Heath, Brianna; Rogers, Sally; Wu Nordahl, Christine; Solomon, Marjorie; Amaral, David G. – Journal of Autism and Developmental Disorders, 2021
Autism symptom severity change was evaluated during early childhood in 125 children diagnosed with autism spectrum disorder (ASD). Children were assessed at approximately 3 and 6 years of age for autism symptom severity, IQ and adaptive functioning. Each child was assigned a change score, representing the difference between ADOS Calibrated…

Avlund, Sara Højslev; Thomsen, Per Hove; Schendel, Diana; Jørgensen, Meta; Clausen, Loa – Journal of Autism and Developmental Disorders, 2021
The present study aimed to explore clinical trends in the period 2000-2010, along with discriminating clinical factors for autism spectrum disorder (ASD), in young children suspected of ASD. The following trends were observed: (1) a rise in referrals including an increase in referrals among language-abled children, (2) an increase in children…

Avlund, Sara Højslev; Thomsen, Per Hove; Schendel, Diana; Jørgensen, Meta; Carlsen, Anders Helles; Clausen, Loa – Journal of Autism and Developmental Disorders, 2021
This study aimed to investigate factors associated with a delayed autism spectrum (ASD) diagnosis when compared to children with either no or early ASD diagnosis. Among 893 children assessed for ASD before age 8, 39% had no ASD at baseline, of which 21% received a later ASD diagnosis. Autism symptoms, diagnostic history of other developmental…

Stichter, Janine; Stormont, Melissa; Buranova, Nargiza; Herzog, Melissa; O'Donnell, Rose – Journal of Autism and Developmental Disorders, 2021
Research continues to highlight discrepancies between clinical diagnoses of Autism Spectrum Disorder (ASD) and determination of special education eligibility for services within school settings. However, limited research has been conducted on the impact of those discrepancies for the identification of appropriate services within schools. The aim…

O'Rourke, Emme; Coderre, Emily L. – Journal of Autism and Developmental Disorders, 2021
While many individuals with autism spectrum disorder (ASD) experience difficulties with language processing, non-linguistic semantic processing may be intact. We examined neural responses to an implicit semantic priming task by comparing N400 responses--an event-related potential related to semantic processing--in response to semantically related…

Levinson, Sarah; Neuspiel, Juliana; Eisenhower, Abbey; Blacher, Jan – Journal of Autism and Developmental Disorders, 2021
ASD symptomology and behavioral problems pose challenges for children with ASD in school. Disagreement between parents and teachers in ratings of children's behavior problems may provide clinically relevant information. We examined parent-teacher disagreement on ratings of behavior problems among children with ASD during the fall and spring of the…
