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…

Accuracy of the Screening Tool for Autism in Toddlers and Young Children in the Primary Care Setting
Rebecca McNally Keehn; Noha F. Minshawi; Qing Tang; Brett Enneking; Tybytha Ryan; Ann Marie Martin; Angela Paxton; Patrick O. Monahan; Mary Ciccarelli; Brandon Keehn – Autism: The International Journal of Research and Practice, 2025
Feasible and accurate assessment tools developed for non-specialists are needed to scale community-based models of autism evaluation. The purpose of this study was to evaluate use of the Screening Tool for Autism in Toddlers and Young Children (STAT) when used by primary care practitioners (n = 10) across a statewide system of early diagnosis set…

Simpson, Allison; Bundy, Myra Beth; Wygant, Dustin B. – Journal of Mental Health Research in Intellectual Disabilities, 2022
Introduction: With the increasing prevalence of Autism Spectrum Disorder (ASD) in recent years, there has been a significant interest in diagnostic accuracy and patterns of autism. Behavior checklists, such as the Autism Spectrum Rating Scale (ASRS), are widely used in psychological evaluations, and while some evidence supports their use in autism…

Lai, Kelly Y. C.; Yuen, Emily C. W.; Hung, Se Fong; Leung, Patrick W. L. – Journal of Autism and Developmental Disorders, 2022
This study examines the psychometric properties of the Autism Diagnostic Interview-Revised (ADI-R) in the context of DSM-5 in a sample of Chinese children. Using re-mapped ADI-R items and algorithms matched to DSM-5 criteria, and administering to children with autism spectrum disorder (ASD) with and without intellectual disability,…

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…

Objective: States in the United States differ in how they determine special education eligibility for autism services. Few states include an autism-specific diagnostic tool in their evaluation. In research, the Autism Diagnostic Observation Schedule (ADOS for first edition, ADOS-2 for second edition) is considered the gold-standard autism…

Medda, Juliane E.; Cholemkery, Hannah; Freitag, Christine M. – Journal of Autism and Developmental Disorders, 2019
The aim of the present study was to establish diagnostic validity of the new algorithm of the Autism Diagnostic Observation Scale, the ADOS-2, to differentiate between ASD and other clinically relevant psychiatric and developmental disorders in a large German sample. Validity of ADOS and ADOS-2 diagnostic algorithms was established in 826…

Educational and Diagnostic Classification of Autism Spectrum Disorder and Associated Characteristics
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…

Wawer, Aleksander; Chojnicka, Izabela – International Journal of Language & Communication Disorders, 2022
Background: Deficits in the ability to use language in social contexts, including storytelling skills, are observed across the autism spectrum. Development in machine-learning approaches may contribute to clinical psychology and psychiatry, given its potential to support decisions concerning the diagnosis and treatment of psychiatric conditions…

Ellison, Kimberly; Bundy, Myra Beth; Gore, Jon; Wygant, Dustin – Exceptionality, 2019
With the publication of "DSM-5," clinical assessment of Autism Spectrum Disorder (ASD) has begun to follow a new dimensional framework which includes new severity specifiers. Little research has explored these severity ratings in comparison to other previously established severity indicators (e.g. "ADOS-2" calibrated severity…

Haiying Yuan; Christine Dollaghan – Journal of Speech, Language, and Hearing Research, 2020
Purpose: No diagnostic tools exist for identifying social (pragmatic) communication disorder (SPCD), a new "Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition" category for individuals with social communication deficits but not the repetitive, restricted behaviors and interests (RRBIs) that would qualify them for a…

Cohen, Ira L.; Liu, Xudong; Hudson, Melissa; Gillis, Jennifer; Cavalari, Rachel N. S.; Romanczyk, Raymond G.; Karmel, Bernard Z.; Gardner, Judith M. – Canadian Journal of School Psychology, 2017
The PDD Behavior Inventory (PDDBI) has recently been shown, in a large multisite study, to discriminate well between autism spectrum disorder (ASD) and other groups when its scores were examined using a machine learning tool, Classification and Regression Trees (CART). Discrimination was good for toddlers, preschoolers, and school-age children;…

Ward, Samantha L.; Sullivan, Karen A.; Gilmore, Linda – Journal of Intellectual & Developmental Disability, 2017
Background: Both parent-report and clinician-administered autism spectrum disorder (ASD) screening instruments are important to accurately inform ASD risk ascertainment. The aim of this study was to adapt a clinician-administered ASD screening instrument, the Autistic Behavioural Indicators Instrument (ABII), as a parent questionnaire equivalent…

Ward, Samantha L.; Sullivan, Karen A.; Gilmore, Linda – Educational and Developmental Psychologist, 2016
Objective: Limited time and resources necessitate the availability of accurate, inexpensive and rapid diagnostic aids for Autism Spectrum Disorder (ASD). The Autistic Behavioural Indicators Instrument (ABII) was developed for this purpose, but its psychometric properties have not yet been fully established. Method: The clinician-rated ABII, the…

We integrated multiple behavioural and developmental measures from multiple time-points using machine learning to improve early prediction of individual Autism Spectrum Disorder (ASD) outcome. We examined Mullen Scales of Early Learning, Vineland Adaptive Behavior Scales, and early ASD symptoms between 8 and 36 months in high-risk siblings (HR; n…
