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…

Emma Pritchard-Rowe; Carmen de Lemos; Katie Howard; Jenny Gibson – Autism: The International Journal of Research and Practice, 2025
Play is often included in autism diagnostic assessments. These tend to focus on 'deficits' and non-autistic interpretation of observable behaviours. In contrast, a neurodiversity-affirmative assessment approach involves centring autistic perspectives and focusing on strengths, differences and needs. Accordingly, this study was designed to focus on…

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…

Luallin, Stephanie; Hulac, David; Pratt, April A. – Psychology in the Schools, 2022
As rates of autism spectrum disorder (ASD) increase, there is an increasing need for clinicians who offer accurate ASD assessments. The Autism Diagnostic Observation Schedule, Second Edition (ADOS-2) is a standardized assessment tool that is commonly recommended for use in comprehensive ASD evaluations. However, practitioners do not always follow…

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…

Duesenberg, McKinzie D.; Burns, Matthew K. – Psychology in the Schools, 2022
Autism spectrum disorder (ASD) is often diagnosed by clinical practitioners with criteria from the American Psychiatric Association, but an educational diagnosis is usually based on state special education law and is geared towards addressing concerns within schools. The current study aims to examine the extent to which the clinical diagnosis of…

Wittkopf, Sarah; Stroth, Sanna; Langmann, Anika; Wolff, Nicole; Roessner, Veit; Roepke, Stefan; Poustka, Luise; Kamp-Becker, Inge – Autism: The International Journal of Research and Practice, 2022
Autism spectrum disorder shares many symptoms with other mental health disorders, and comorbid disorders such as mood and anxiety disorders are common, making the diagnostic process challenging. We aimed to explore the diagnostic accuracy of two standard autism spectrum disorder diagnostic instruments and to identify those behavioral items that…

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…

Amy Camodeca – Journal of Psychoeducational Assessment, 2024
There is a need to investigate the diagnostic utility of autism diagnostic questionnaires in school-age children, who are increasingly being referred for autism assessment. Aside from the standardization sample, little research has been conducted on the Autism Spectrum Rating Scales, particularly regarding teacher reports. This study investigated…

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…

Background & Aims: Narratives are regularly elicited as part of standardized assessments for autism spectrum conditions (ASC) such as the ADOS, but have rarely been utilized as linguistic data in their own right. We here aimed for a specific and comprehensive quantitative linguistic profile of such narratives across nominal, verbal, and…
