Measurement invariance (MI) is a psychometric property of an instrument indicating the degree to which scores from an instrument are comparable across groups. In recent years, there has been a marked uptick in publications using MI in intellectual and developmental disability (IDD) samples. Our goal here is to provide an overview of why MI is…

Inclusive research emphasizes the importance of researchers with intellectual and developmental disabilities playing active roles in all phases of research, including research and information dissemination. This article explores how contemporary literature and practical application of inclusive practices in the academic setting of a University…

Children with intellectual and developmental disabilities and extensive support needs (ESN) face a high risk of experiencing traumatic events, which may lead to a myriad of negative mental and physical health and educational outcomes. Identifying symptoms and treating trauma, however, are challenging due to communication difficulties, vague or…

Although approximately a third of individuals with intellectual and developmental disabilities (IDD) also experience a mental health concern, caregivers often miss early identification of these issues. In this perspective piece, we present an outline for a mental health literacy program that can enhance existing training approaches for caregivers…

In both research and practice, gaining assent from participants is an ethical imperative in applied behavior analysis. Recent guidance for including assent-based procedures has been provided in the literature (Breaux & Smith, 2023). However, limitations for decision-making when working with individuals who have developmental disabilities and…

Aging family caregivers of adults with intellectual and developmental disabilities (IDD) have unique circumstances setting them apart from the general caregiving population. Such differences include the extensive duration of the caregiving, and health concerns that manifest in the caregiver and individuals with IDD over time. Because of increasing…

Planning inclusive research should center meaningful engagement of co-researchers with intellectual and/or developmental disabilities to address issues that are important to their communities. There are a variety of approaches to planning research projects consistent with the guiding principles of inclusive research. We describe components of…

The aim of this study was to develop a transcultural adaptation of the Diagnostic Adaptive Behavior Scale (DABS) in French and to perform a field evaluation of the adapted version of the tool (DABS-F). Eight experts in intellectual and developmental disabilities (IDD) and two professional translators formed two committees to translate the…

The COVID-19 pandemic has been hard for everyone. For the estimated seven and a half million people in the United States who live with intellectual disability (Residential Information Systems Project, 2020), it has been very hard. Lives have been disrupted by lost jobs, lack of access to friends/family, and challenges finding enough staff to…

Estimates are also…

New partnerships to reach new audiences are key to Extension's future (Harder, 2019). But partnership is enhanced through shared decision-making, co-creation of content, and leveraging non-overlapping expertise and experience (Bertsch et al., 2020; Israilov & Cho, 2017; Ostrom, 1996). Texas A&M AgriLife Extension Service partnering with…

While the intersections of normalization and outsider art have been articulated in studio art therapy practice with people labeled/with IDD, little attention has been given to the intersection of art therapy, artists labeled/with IDD and disability art. As a counter-cultural endeavor rooted in a political movement, disability art offers a distinct…

Background: Often, people with and without intellectual disabilities do not mingle. Research has mostly focused on how to foster "convivial encounters" for social inclusion, but further thinking is needed on situations in which potential encounters do not take place. Method: Discussion of philosophical and urban sociological literature…

This systematic review examined 14 U.S. studies published since 2000 reporting prevalence estimates for intellectual disability (ID) or developmental disability (DD). Prevalence rates for children were between 11.0 and 13.4 per 1,000 for ID and between 45.8 and 69.9 per 1,000 for DD using data from 2010 or later. A 2015 Ohio study of adults…

Youth with intellectual and developmental disabilities (IDD) aspire to participate in a variety of activities after high school, such as attaining paid employment, enrolling in postsecondary education, being involved in their communities, living independently, and building friendships. However, complex and longstanding transition barriers require…
