Despite the high incidence of bullying among people with intellectual and developmental disabilities (IDD), little research has been conducted with people with IDD as participants reporting their own perceptions and experiences of bullying. To address this shortcoming, we interviewed 18 adults with IDD regarding these issues. Four major themes…

Purpose: Interprofessional practice requires regular communication between professionals from different disciplines using shared terminology. Within schools, many professionals are tasked with supporting children with language disorders, namely, developmental language disorder (DLD) and/or dyslexia. Limited information exists as to (a) how…

This study (a) examines the role of cognitive abilities, age and vocabulary in the development of definitions and (b) compares the development of definitions (in content and form) in children with and without Developmental Language Disorder (DLD). Definitions have been extensively studied in (non-)impaired populations. So far, no studies have…

Background: Lack of agreement about criteria and terminology for children's language problems affects access to services as well as hindering research and practice. We report the second phase of a study using an online Delphi method to address these issues. In the first phase, we focused on criteria for language disorder. Here we consider…

Purpose: The goal was to determine whether interactive book reading outcomes for children with developmental language disorder (DLD) were affected by manipulation of dose (i.e., the number of exposures to the target word during a book reading session) and dose frequency (i.e., the number of repeated book reading sessions) and whether pretreatment…

When researchers evaluate adult outcomes for individuals with intellectual and/or developmental disabilities (IDD), the perspective of families is not always considered. Parents of individuals with IDD ("N" = 198) answered an online survey about their definition of a successful transition to adulthood. Content analysis was used to…

This study outlines the literature relevant to the Cross-cultural issues and the politics of SEN and the different perspectives arising from the literature on this widely debated issue are addressed. In addition, the origin of the term "special educational needs" (SEN), its definitions and the types of special education needs are…

Fetal alcohol spectrum disorder (FASD) is a prevalent neurodevelopmental disability with significant implications for learning and behaviour. International research suggests that the prevalence of FASD in school-aged children is 2.3-6.3%. In this paper, we address the questions: (1) what is FASD; (2) what is the prevalence of FASD in schools; (3)…

The purpose of this study was to examine teacher perspectives about evidence-based practices (EBP) and decision-making for students with intellectual and developmental disabilities. Given the current EBP movement, our study sought to understand practitioner definitions and perspectives on EBP and decision-making. Interview data from nine special…

This "Policy Research Brief" summarizes publicly-available data sources that provide information about the employment of people with intellectual and developmental disabilities. It provides important information about these data sources, including their purposes, key definitions, and where to access the public data. Using these data…

Five groups of children defined by presence or absence of syntactic deficits and autism spectrum disorders (ASD) took vocabulary tests and provided sentences, definitions, and word associations. Children with ASD who were free of syntactic deficits demonstrated age-appropriate word knowledge. Children with ASD plus concomitant syntactic language…

Results suggested that potential inclusion within the functional developmental disabilities definition of P.L. 95-602, the Developmental Disabilities Amendments of 1978, varies as a function of categorical disability, age, and level of intellectual functioning. (Author)

In a field trial addressing revisions to autism criteria in the fourth edition of the Diagnostic and Statistical Manual (DSM-IV), information on 977 cases (454 with autism, 240 with "autistic-like" conditions, and 283 with nonpervasive developmental disabilities disorders) was rated. DSM-IV criteria were compared with the International…

This article criticizes the term "comorbidity" used to describe the overlap of developmental syndromes or disorders. Data from 179 school-age children are evaluated for criteria of seven disorders. Since fully 50 percent of the sample met the criteria for at least two diagnoses, the premise that these disorders are discrete categories on…

Three databases were analyzed to investigate the range and frequency of terms in the field of mental retardation/developmental disabilities. The most prevalent term over the last 15 years was "mentally retarded." The terms "cognitive impairment" and "developmental disabilities" have been used more frequently in the last five years.
