Purpose: The experiment reported here compared two hypotheses for the poor statistical and artificial grammar learning often seen in children and adults with developmental language disorder (DLD; also known as specific language impairment). The "procedural learning deficit hypothesis" states that implicit learning of rule-based input is…

Inpatient hospitalizations for ambulatory care sensitive conditions (ACSC) among beneficiaries with and without intellectual and developmental disabilities (IDD) were examined using Medicaid and commercial claims from 2010-2014 in New Hampshire. IDD was defined with "International Classification of Diseases, Ninth Edition, Clinical…

The Vineland-3 purports to measure three dimensions of adaptive behavior, but empirical evidence pertaining to its structural validity is lacking. In this study, factor analyses were conducted on the standardization sample data for the comprehensive forms within the 11- to 20-year-old age range. Results did not support the three domain structure…

Over the past several decades, we have developed quality behavioral assessments and interventions for challenging behaviors among individuals with a variety of severe developmental and cognitive disorders. These assessments and interventions have been used to educate family members on how to understand and intervene with these behaviors at home…

Purpose: While most of the children who are identified as late talkers at the age of 2 years catch up with their peers before school age, some continue to have language difficulties and will later be identified as having developmental language disorder. Our understanding of which children catch up and which do not is limited. The aim of the…

In this article, we demonstrate the potential of machine learning approaches as inductive analytic tools for expanding our current evidence base for policy making and practice that affects people with intellectual and developmental disabilities (IDD). Using data from the National Core Indicators In-Person Survey (NCI-IPS), a nationally validated…

Fetal alcohol spectrum disorder (FASD) is a diagnostic term used to describe an array of structural, neurocognitive, and behavioral effects that result from prenatal alcohol exposure. While ongoing efforts have been made to increase the capacity of communities to provide early FASD diagnosis, there continues to be on-going challenges, particularly…

Background: Women with intellectual and developmental disabilities face poorer reproductive and pregnancy outcomes partially due to health care inequity. Our objective was to conduct a scoping review of reproductive and pregnancy related health care among women with intellectual and developmental disabilities. Methods: We systematically reviewed…

Children with developmental language disorder (DLD) served as a test case for determining the role of extant vocabulary knowledge, endogenous attention, and phonological working memory abilities in cross-situational word learning. First-graders (M[subscript age] = 7 years; 3 months), 44 with typical development (TD) and 28 with DLD, completed a…

Background/Aims: This study describes the process of developing video vignettes to meet the parent-expressed need for balanced, meaningful messages about what life may be like for parents who have a child with a disability. Each vignette teaches a general audience salient concepts derived from a grounded theory of the parental process of Rescuing…

Background: The abuse of adults with intellectual and developmental disabilities in care services seems to be relatively common, although there are anecdotal suggestions that abuse may be predictable and preventable. Method: Evidence related to how abuse is detected and prevented within services was reviewed. Database and ancestry searches were…

Postsecondary educational programs (PSEs) are increasingly an option for students with intellectual and developmental disabilities (IDD). This scoping review synthesized research to understand the impacts of these programs for students with IDD and for campus, and barriers to these programs across stages of engagement (exploration, participation,…

There is a long history of individuals with extensive support needs (ESN) being sterilized without their knowledge and consent. Students with ESN are defined as individuals who need continuous and widespread supports necessary for academic, communication, and/or daily living skills. These individuals typically have more than one diagnosis…

Purpose: This systematic review provides a comprehensive summary of the diagnostic accuracy of English language sample analysis (LSA) measures for the identification of developmental language disorder. Method: An electronic database search was conducted to identify English publications reporting empirical data on the diagnostic accuracy of English…

Background: We conducted feasibility testing of a novel peer mentoring intervention addressing self-awareness and proactive coping for young adults with intellectual and developmental disabilities and co-occurring mental health conditions. Aligned with regulatory flexibility theory, we hypothesised that if young adults with intellectual and…
