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…

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…

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…

Autism spectrum disorder presents as a multifaceted condition characterized by pronounced impairments in social communication and behavioral patterns. Diagnosis hinges upon the expertise of clinicians, comprehensive developmental history, and observation of specific behavioral markers. However, in low-income countries, access to screening tools…

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…

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…

This study examined the reliability and validity of the 13-item Classroom Observation Scale as used by teachers and non-clinically trained observers to identify children who more likely than their peers to have autism spectrum disorder in less-resourced preschools. A total of 534 children (ages 2;10 to 4;5, Mean = 3;8) from nine Chinese-language…

Few measures are appropriate to assess autism symptoms in minimally verbal adolescents and adults. The Autism Diagnostic Observation Schedule, 2nd Edition (ADOS-2, Lord et al., in Autism diagnostic observation schedule--2nd edition (ADOS-2). Western Psychological Services, Los Angeles, 2012) Modules 1 and 2 were designed and validated with…

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…

The Early Learner Curriculum and Achievement Record (ELCAR, Greer et al., 2020) is a criterion-referenced curriculum and assessment of children's development of language and social repertoires from the earliest foundational observing responses to advanced verbal repertoires. The developmental cusps or stages identified in the ELCAR have been…

Children with autism spectrum disorder benefit from early, intensive interventions to improve social communication, and parent-implemented interventions are a feasible, family-centered way to increase treatment dosage. The success of such interventions is dependent on a parent's ability to implement the strategies with fidelity. However,…

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…

Purpose: Social communication or pragmatic skills are continuously distributed in the general population. Impairment in these skills is associated with two clinical disorders, autism spectrum disorder (ASD) and social (pragmatic) communication disorder. Such impairment can impact a child's peer acceptance, school performance, and current and later…

Most social communication tests used to measure change in young children with autism spectrum disorder have not undergone rigorous psychometric evaluation. Notably, and most relevant to the early intervention literature, there is little information on the sensitivity of these measures to change over time, despite their frequent use. Further, most…
