Ingrid S. Tien; Amanda R. Johnson; Junok Kim; Jeffrey J. Wood – Journal of Autism and Developmental Disorders, 2025
Approximately 3-4 boys for every girl meet the clinical criteria for autism in studies of community diagnostic patterns and studies of autism using samples of convenience. However, girls with autism have been hypothesized to be underdiagnosed, possibly because they may present with differing symptom profiles as compared to boys. This secondary…

Grzadzinski, Rebecca; Jatkar, Alapika; Donovan, Kevin; Truong, Kinh; Holbrook, Alison; Lord, Catherine; Kim, So Hyun – Journal of Autism and Developmental Disorders, 2023
The evaluation of the overlap between the ADOS BOSCC and Standard BOSCC as well as the exploration of child characteristics that may predict change are important steps in consolidating data-driven definitions of "improvement". Participants were seen between 2 and 5 times with Standard BOSCC and ADOS BOSCC observations over the course of…

Katherine Byrne; Kyle Sterrett; Alison Holbrook; So Hyun Kim; Rebecca Grzadzinski; Catherine Lord – Journal of Autism and Developmental Disorders, 2024
The current study investigated the utility of the Brief Observation of Social Communication Change-Phrase Speech Young Fluent (BOSCC-PSYF) as an outcome measure of treatment response by analyzing the measure's psychometric properties and initial validity. The BOSCC coding scheme was applied to 345 administrations from 160 participants diagnosed…

Maja Cepanec; Sanja Šimleša – Journal of Autism and Developmental Disorders, 2024
Most internationally recognized instruments for the screening and diagnosis of autism spectrum disorder have been developed in the USA, which calls into question the degree of their cultural adaptation to diverse populations. The aim of this study is to examine the characteristics of social communication in typically developing Croatian-speaking…

Sophie Shapter; Amy Carroll; Kate Roberts – Journal of Autism and Developmental Disorders, 2025
The COVID-19 pandemic and the subsequent social distancing policies forced healthcare teams to drastically alter the way they deliver services. This was particularly challenging for clinicians involved in diagnosing autism spectrum disorder (ASD), as assessment tools and methods required face-to-face social interactions between clinicians and…

We report a Delphi Consensus modification and first validation study of the Autism Diagnostic Observation Schedule -- 2 with deaf children and young people (ADOS-2 Deaf adaptation). Validation included 122 deaf participants (aged 2-18 years), 63 with an Autism Spectrum Disorder (ASD). This was compared to a National Institute for Health and…

Janvier, Denisse; Choi, Yeo Bi; Klein, Claire; Lord, Catherine; Kim, So Hyun – Journal of Autism and Developmental Disorders, 2022
Describing the relative severity and change in autism symptoms is crucial for the appropriate characterization of clinical and research populations. The calibrated severity score (CSS) of the Autism Diagnostic Observation Schedule-2 (ADOS-2; Lord et al., 2012) was created to better describe autism symptom severity consistently across different…

Aaronson, Benjamin; Estes, Annette; Rogers, Sally J.; Dawson, Geraldine; Bernier, Raphael – Journal of Autism and Developmental Disorders, 2022
We examined the relationship between the Early start Denver model (ESDM) intervention and mu rhythm attenuation, an EEG paradigm reflecting neural processes associated with action perception and social information processing. Children were assigned to either receive comprehensive ESDM intervention for two years, or were encouraged to pursue…

Daniel Berends; Catherine A. Bent; Giacomo Vivanti; Cheryl Dissanayake; Kristelle Hudry – Journal of Autism and Developmental Disorders, 2024
Purpose: While research indicates that both the core features of autism and associated developmental skills influence adaptive behaviour outcomes, results to date suggest greater influence of the latter than the former, and little attention has been given to how the interaction of both together might impact functional disability. Seeking to expand…

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…

Holzinger, D.; Weber, C.; Bölte, S.; Fellinger, J.; Hofer, J. – Journal of Autism and Developmental Disorders, 2022
This study describes the adaptation of the autism diagnostic observation schedule (ADOS-2) to assess autism spectrum disorder (ASD) in adults with intellectual disability (ID) and hearing loss who communicate primarily visually. This adapted ADOS-2 was applied to residents of specialized therapeutic living communities (n = 56). The internal…

Palmer, Melanie; Tarver, Joanne; Carter Leno, Virginia; Paris Perez, Juan; Frayne, Margot; Slonims, Vicky; Pickles, Andrew; Scott, Stephen; Charman, Tony; Simonoff, Emily – Journal of Autism and Developmental Disorders, 2023
Emotional and behavioral problems (EBPs) frequently occur in young autistic children. Discrepancies between parents and other informants are common but can lead to uncertainty in formulation, diagnosis and care planning. This study aimed to explore child and informant characteristics are associated with reported child EBPs across settings.…

Zagury-Orly, Ivry; Kroeck, Mallory R.; Soussand, Louis; Cohen, Alexander Li – Journal of Autism and Developmental Disorders, 2022
Face-processing deficits, while not required for the diagnosis of autism spectrum disorder (ASD), have been associated with impaired social skills--a core feature of ASD; however, the strength and prevalence of this relationship remains unclear. Across 445 participants from the NIMH Data Archive, we examined the relationship between Benton Face…

Michelle L. Stransky; Laneva Cobb; Nina Menon; Emily Barnard; Cynthia Belfleur; Lawrence Scahill; Jocelyn Kuhn – Journal of Autism and Developmental Disorders, 2025
The National Institute of Mental Health created the National Database for Autism Research (NDAR) to accelerate autism knowledge through data sharing and collaboration. However, our experience using NDAR reveals systematic challenges across several aspects of data submission, selection, management, and analysis that limit utility of this resource.…
