The present study explored the shift from understanding to intervention to population impact in the empirical research published in this journal at five points of time over 40 years since the release of DSM-III. Two-thirds of the more than 600 original studies identified involved basic research, a pattern that is consistent with previous analyses…

The clinical similarity among different neuropsychiatric disorders (NPDs) suggested a shared genetic basis. We catalogued 23,109 coding de novo mutations (DNMs) from 6511 patients with autism spectrum disorder (ASD), 4,293 undiagnosed developmental disorder (UDD), 933 epileptic encephalopathy (EE), 1022 intellectual disability (ID), 1094…

Children with developmental disabilities require more medical experiences than typically-developing children and struggle to cooperate with healthcare encounters. Adaptive care plans, delivered by child life specialists, are individualized patient-centered plans created to address the challenges that children with developmental disabilities…

This qualitative study explored the knowledge and perceptions about early screening for developmental disabilities and autism spectrum disorder (ASD) in childcare settings using semistructured interviews with directors, teachers, and parents at 12 childcare centers. Results indicated that most of the directors and teachers, who were interviewed,…

Family-professional partnership is an essential component of the special education process for children with intellectual and/or developmental disabilities (IDD), including autism spectrum disorder (ASD). Latinx families face systemic barriers when participating in educational decision-making for their children with IDD. Few studies have examined…

Content validity describes the extent to which a measure represents, and is relevant to, the construct it aims to assess. The International Classification of Functioning, Disability and Health and derived Core/Code Sets (Sets) for autism, attention deficit-hyperactivity disorder, cerebral palsy and early developmental delay and disability are…

Programmes which offer integrated services were analysed to identify model international and domestic programmes serving adults with neurodevelopmental disorders. Programmes were assessed according to 11 need domains identified in a previous study: supervision, transportation, housing, communication, finances/employment opportunities, activities…

Prevalence of developmental disorders (DDs) has been increasing worldwide. This study identifies a trend in their prevalence and incidence, using nationwide population-based data to analyze the characteristics of children with DDs in Korea. The prevalence of DDs steadily increased by more than four times (from 0.6 to 2.5) from 2003 to 2017. Boys…

The goal of this preliminary investigation was to compare demographic and clinical characteristics in a sample of children with likely Social (Pragmatic) Communication Disorder (SCD) (N = 117) to those in children with possible (N = 118) and some (N = 126) SCD traits, other developmental delay (DD) (N = 91) and autism spectrum disorder (ASD) (N =…

This study assessed 155 healthcare providers, from nine disciplines, who work professionally with people with intellectual and developmental disabilities (IDD). Using a national, web-based survey, respondents rated their experience, comfort, and competence in treating individuals with different disability types and preferred methods of continuing…

The use of telehealth technologies to provide clinical services to families of children with autism and other developmental disabilities is a rapidly growing area of research. In particular, remote training of caregivers via video conferencing appears to be a promising approach for disseminating behavior-analytic interventions (Neely et al. in…

Motor abnormalities are highly prevalent in children with autism spectrum disorder and are strongly predictive of adaptive functioning. Despite the documented sex bias in the prevalence of the disorder, the impact of sex differences on motor abnormalities has been overlooked. The goal of this study was to investigate differences in the motor…

Neuromyths are commonly held misconceptions about the brain believed by both the general public and educators. While much research has investigated the prevalence of myths about the typically developing brain, less attention has been devoted to the pervasiveness of neuromyths about neurodevelopmental disorders, which have the potential to…

Purpose: Children with autism spectrum disorders (ASDs) and children with developmental language disorder (DLD) face challenges with pragmatics, but the nature and sources of these difficulties are not fully understood yet. The purpose of this study was to compare the competence of children with ASD and children with DLD in two pragmatics tasks…

Truncating variants of the "MAGEL2" gene, one of the protein-coding genes within the Prader-Willi syndrome (PWS) critical region on chromosome 15q11, cause Schaaf-Yang syndrome (SYS)--a neurodevelopmental disorder that shares several clinical features with PWS. The current study sought to characterize the neurobehavioral phenotype of SYS…
