The purpose of this qualitative descriptive study was to explore how special education teachers describe selecting and applying differentiated instructional strategies for students with mild, moderate, to severe disabilities in self-contained classrooms within a school district in Arizona. Jean Piaget's social constructivism theory and Carol Ann…

New opportunities for postsecondary education have emerged for young adults with intellectual disability. As a growing number of institutions establish inclusive higher education programs, it is important to understand the experiences of faculty who welcome students with intellectual disability into their courses. This qualitative study explored…

Background: Patient-reported outcome measures (PROMs) are increasingly used in health care to evaluate service quality and client progress. Response scales are a critical component of PROM content validity and must be designed to be relevant and comprehensible by users. Methods: In collaboration with eight youth co-researchers with…

Background: Study of frailty in adults with intellectual and developmental disabilities (IDD) is relatively new. To build the body of literature, an international consensus statement on how to support adults with IDD as they become frail was developed based on fictional cases. This study examined the face validity and applicability of the…

Although our field has made significant progress in the measurement of procedural fidelity in research studies, we argue for a more nuanced and expansive perspective on procedural fidelity. Specifically, we review the status quo of procedural fidelity measurement in intervention research along with specific suggestions for increasing both…

This article explores what it means to include intellectual disability (ID) in philosophical discourse and in the philosophy classroom. Taking Audre Lorde's claim that "the master's tools will never dismantle the master's house" as a starting point, it asks how certain forms of cognitive ableism have excluded ID from the…

There is an increasing emphasis on the importance of research having an impact on policy and practice. This can be more difficult to evidence in intellectual disability services because of the wide range of stakeholders involved. We evaluated whether an impact questionnaire covering: knowledge production, capacity building, informing policy and…

The study's aim was to explore the capacity of community-based providers of residential supports and services to support people with intellectual and developmental disabilities who transitioned out of state-operated institutions into community-based settings. Receiving agency survey results from 65 agencies and individual-level variables of 2,499…

The researchers conducted a qualitative case study to describe the teaching and learning of a third grade student with a learning disability as he worked on multiplicative tasks with a tutor. The student's strategies, at participatory and anticipatory levels of understanding, were analyzed to inform instructional decisions we made to support the…

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…

Background: Insight in health-related quality of life (HRQoL) of adults with severe disabilities who are non-ambulatory is important, but a measure is lacking. The aim was to develop a HRQoL measure for this group. Method: The developmental process consisted of the adaptation process of a proxy HRQoL measure for children with severe disabilities…

Postsecondary education (PSE) programs allow for college students with intellectual disability to experience a higher level of autonomy in choice making, which they may not have experienced in their family home or high school. This includes choice making related to romantic and sexual relationships. The "Continuum of Support for Intimacy…

Students with disabilities, including those with learning disabilities (LD) experience difficulties transitioning to post-school environments. A Summary of Performance (SOP) document, provided to students with disabilities during their final year of high school, may serve as a platform for requesting access to services from post-secondary service…

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…
