Due to the unique social cognitive profiles of individuals with autism spectrum disorder (ASD) with and without intellectual disability (ID) sharing coherent and complex personal narratives can be challenging. To address these challenges research has focused on teaching macrostructure components using visual supports and repeated opportunities to…

Fragile X syndrome (FXS), as a monogenic cause of intellectual disability and autism spectrum disorder, has been one of the first neurodevelopmental disorders in which molecular and neuronal mechanisms of disease have been identified, leading to the concept of targeting the underlying disease to reverse symptoms. Translating findings in basic…

The purpose of this study was to compare the relative effects of word reading and story component interventions in developing reading comprehension of narrative texts with four students with mild levels of intellectual disability. A multielement design was used in this study. The findings revealed that the story component intervention was more…

This article summarizes research focusing on communication skills of people with intellectual and developmental disabilities (IDD) who communicate primarily without speech, sign language, or augmentative communication. Importantly, developmental theories were emphasized as useful for interpreting communication in children and adults. These studies…

The NIH Toolbox Cognition Battery (NIHTB-CB) was developed for epidemiological and longitudinal studies across a wide age span. Such a tool may be useful for intervention trials in conditions characterized by intellectual disability (ID), such as Williams syndrome (WS). Three NIHTB-CB tasks, including two executive functioning (Flanker,…

This meta-analytic review investigated interventions for transition-age youth diagnosed with autism, intellectual disability, or extensive support needs. Nineteen group design studies with 215 effect sizes met inclusion criteria. A robust variance estimation procedure that accounts for the clustering effect sizes within studies was used to…

The purpose of this study was to examine self-determination outcome data in the year following a one-year cluster randomized controlled trial (C-RCT) comparing the impacts of a Self-Determined Learning Model of Instruction (SDLMI) only condition to a SDLMI + "Whose Future Is It?" (SDLMI + WF) condition. Using multilevel B-spline model…

This study examined the efficacy of exercise programs for individuals with intellectual disability (ID) based on experimental designs. Multiple databases were searched from inception up until March 2019. Randomized control trials were eligible for inclusion if they (a) included a population with ID; (b) used an exercise intervention; and (c)…

Inappropriate sexual behavior (ISB) is a common, but understudied, issue for individuals diagnosed with developmental disabilities (DD), intellectual disability (ID), and/or acquired brain injuries (ABI). We conducted a systematic review to identify, analyze, and synthesize published behavior-analytic approaches to intervention for ISB in DD, ID,…

Through a scoping review, the current state of physical activity research in people with intellectual disability was examined. A search of publications between 2000 and 2014 retrieved 362 articles that met inclusion criteria. Eligible studies were coded according to the Behavioral Epidemiological Framework. Of the articles identified, 48% examined…

Interventions that promote parent and child well-being in families with children with intellectual and developmental disabilities (IDD) are important, given the caregiving burden often associated with supporting children with developmental and behavioral challenges. This article summarizes a presentation made at the 2019 AAIDD annual conference…

This study evaluated the effects of a pyramidal training approach that used an expert trainer who taught teachers how to train their paraeducators. Three special education teachers were taught to train four paraeducators to provide students with intellectual and developmental disabilities opportunities to initiate (OTI). A multiple baseline design…

Physical activity (PA) rates of adolescents with intellectual and developmental disabilities (IDD) are low and effective strategies for increasing PA are limited. The purpose of this study was to assess the feasibility of a group-based PA intervention that was delivered remotely to adolescents with IDD. Participants attended 30-min group PA…

Some children with Down syndrome may experience difficulties in recognizing facial emotions, particularly fear, but it is not clear why, nor how such skills can best be facilitated. Using a photo-matching task, emotion recognition was tested in children with Down syndrome, children with nonspecific intellectual disability and cognitively matched,…

Research has shown that children with Prader-Willi syndrome (PWS) have social-cognitive challenges and decreased quality parent-child interactions. However, given the low prevalence rate, developing interventions for children with PWS is faced with the significant challenge of enrolling enough participants for local studies. To better understand…
