Early identification of autism spectrum disorder through cost-effective screening is crucial in low- and middle-income countries. The Child Behavior Checklist 1.5-5, using the Autism Spectrum Problems and Withdrawn Syndrome subscales, has potential as a level 1 autism spectrum disorder screening tool, though its construct validity in low- and…

Camodeca, Amy – Journal of Autism and Developmental Disorders, 2023
There is limited research regarding the Gilliam Autism Rating Scales-3rd Edition (GARS-3) despite its extensive use. A comprehensive diagnostic evaluation, including the Autism Diagnostic Observation Schedule--2nd Edition (ADOS-2) was provided to 186 clinically referred children suspected of autism ([x-bar] age = 8.98; Autism [AUT] n = 87; Not…

Michael Terner; Sandra Israel-Yaacov; Ofer Golan – Autism: The International Journal of Research and Practice, 2024
Autism is a neurodevelopmental condition, characterized by altered social communication and repetitive behavior. Typically diagnosed in early childhood, screening and diagnosis at a later age can be challenging, particularly in girls who exhibit a wider range of behaviors and characteristics. This study aimed to examine the Childhood Autism…

Christopher, Kourtney; Lord, Catherine – Psychology in the Schools, 2022
The heterogeneous nature of Autism Spectrum Disorder (ASD) makes accurate diagnosis challenging. Best practice assessments in schools can open pathways to appropriate interventions and educational placements for those with ASD, as well as help identify a student's strengths. There are various tools used in school settings to assess autism. In this…

Primary care providers are often the first to identify concerns for autism through routine screening in the first 2 years of life. However, most children do not receive a diagnosis until years later resulting in delays accessing appropriate intervention. Delays in diagnosis disproportionately impact those who are otherwise disadvantaged by society…

There are inequities in engagement with established early childhood developmental surveillance programs, eclipsing disadvantaged families. The current study sought to address this by dovetailing developmental surveillance with immunization visits and other opportunistic contacts with children at general practices). While 53 General Practices were…

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…

Safer-Lichtenstein, Jonathan; Reardon, Kyle; McIntyre, Laura Lee – Journal of Applied School Psychology, 2021
Special education service delivery may vary, in part, by geographic location of the school districts. This variation may be especially important to understand for students who require comprehensive evaluations and specialized services, such as students with autism spectrum disorder (ASD). Much of the existing literature focuses on geographic…

The prevalence of autism spectrum disorder in the world has increased over the last decade, but the prevalence, incidence, and characteristics of autism spectrum disorder in China were not well understood. Using administrative data, we aimed to estimate the prevalence and incidence of autism spectrum disorder and describe the co-occurring…

Bella, Zachary A. – Communique, 2022
Early identification of ASD allows for clinical intervention through mental and behavioral health supports, potentially providing individualized services in the educational setting. This article highlights the research-to-practice gap that exists within evaluations for ASD in schools. Lack of training, variability in assessment guidelines,…

Fielding-Gebhardt, Heather; Bredin-Oja, Shelley L.; Warren, Steven F.; Brady, Nancy C. – Journal of Autism and Developmental Disorders, 2021
Accurate representation of autism spectrum disorder (ASD) in fragile X syndrome (FXS) is necessary for the field. We examined classifications of ASD using three approaches--Autism Diagnostic Observation Schedule (ADOS-2; Lord et al. 2012), Childhood Autism Rating Scale (CARS2-ST; Schopler et al. 2010), and Vineland Adaptive Behavior Scales…

Two studies were conducted to examine the use of the Taiwanese version of the Screening Tool for Autism in Two-Year-Olds for detecting autism spectrum disorder in toddlers aged 18-24 months. Study 1 used receiver operating characteristics to select a cutoff score for the Taiwanese version of the Screening Tool for Autism in Two-Year-Olds. It…

Autism Spectrum Disorder (ASD) is diagnosed using the same criteria for males and females (e.g., DSM-5, ICD-10). Our understanding of ASD, including its etiology, symptom presentation, and prevalence has evolved significantly over time motivating several changes to the diagnostic criteria and the tools with which symptoms are measured. One aspect…
