The Autism Diagnostic Observation Schedule, 2nd-edition (ADOS-2) Toddler Module is the current gold-standard measure of autism spectrum disorder (ASD), a neurodevelopmental condition more frequently diagnosed in toddler boys than girls. Some evidence suggests that behaviors assessed by the Toddler Module may capture an ASD phenotype that is more…

There have historically been a variety of diagnostic terms used to describe children with unexplained language disorders. Recently there has been some consensus around the use of the term developmental language disorder (DLD) however, students, in particular graduate students, need to be aware of the various terms that have historically been used…

Relatively little has been published about the prevalence of autism in adults with psychiatric disorders. In this study, all new patients referred to an adult psychiatric outpatient clinic in Sweden between November 2019 and October 2020 (n = 562) were screened for autism spectrum disorders using the Ritvo Autism and Asperger Diagnostic Scale…

Background: The frequency and intensity of physical activity are directly related to health in the general population. However, to our knowledge, no study has looked at that relationship in people with intellectual disability. Method: The aim of this study was to determine whether there were differences in the health of 407 people with…

Mental health organizations that serve youth are under pressure to adopt measurement-based care (MBC), defined as the continuous collection of client-report data used to support clinical decision making as part of standard care. However, few frameworks exist to help leadership ascertain how to select an MBC approach for a clinical setting. This…

Optimization is a component critical to method development. Mathematical modeling of physical phenomena enables an efficient search for the parameters and conditions that optimize methods and systems. Here, optimization of methods in sonoelectrochemistry, electrochemical separations, electrochemical education, and assessment of diabetic status are…

There is growing evidence that school starting age impacts children's likelihood of receiving special education services, but less is known about variations in this effect. Using a regression discontinuity design, I found that the youngest students in a kindergarten cohort are 40% more likely (p < 0.001) to be placed in special education than…

Purpose: This article aims to illuminate the process and results of an international consortium project that considered terms and diagnostic criteria used in the identification of children with language problems. Method: The process by which the consortium worked to arrive at its recommendations is considered. The wider implications of accepting…

Purpose: Low-frequency detection thresholds in quiet vary across transducers. This experiment tested the hypothesis that transducer effects are larger in young children than adults, due to higher levels of self-generated noise in children. Method: Listeners were normal-hearing 4.6- to 11.7-year-olds and adults. Warble-tone detection was measured…

Scoping reviews are increasingly used in health professions education to synthesize research and scholarship, and to report on the depth and breadth of the literature on a given topic. In this Perspective, we argue that the philosophical stance scholars adopt during the execution of a scoping review, including the meaning they attribute to…

While multiple theories exist to explain the diagnostic process, there are few available assessments that reliably determine diagnostic competence in trainees. Most methods focus on aspects of the process of diagnostic reasoning, such as the relation between case features and diagnostic hypotheses. Inevitably, detailed elucidation of aspects of…

There is minimal research regarding the personal experiences and perceptions of youth with autism spectrum disorder (ASD). Yet, the positive and negative perceptions that youth internalize about their diagnoses are crucial, as they may have a strong impact on individuals' self-concept and well-being. This paper utilizes mixed methods to describe…

Two semi-structured parental interviews are available with algorithms developed to measure DSM-5 criteria of ASD, namely the Developmental, Dimensional and Diagnostic Interview (3di) and the Diagnostic Interview for Social and Communication Disorders (DISCO-11). The main aim of this study was to examine the agreement between classification…

Meta-analyses of diagnostic test accuracy (DTA) studies have been gaining prominence in research in clinical epidemiology and health technology development. In these DTA meta-analyses, some studies may have markedly different characteristics from the others and potentially be inappropriate to include. The inclusion of these "outlying"…

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…
