This article describes the use of the National Health Interview Survey-Disability Supplement (NHIS-D) to estimate the prevalence and general characteristics of persons with intellectual and/or developmental disabilities in the non-institutionalized U.S. population. It provides estimates of the populations of non-institutionalized persons with intellectual disability (defined categorically), with developmental disabilities (defined functionally) and with both. It describes how the prevalence of intellectual and/or developmental disabilities varies by age, poverty status and other demographic variables. It describes how intellectual disabilities and developmental disabilities are operationally different, and how the people identified in those groups differ substantially both in number and in demographic characteristics. An analysis of poverty status among adults reveals that poverty is significantly more common for women, people who were not white, people with intellectual or developmental disabilities, adults with less than 12 years of education, and people living with a spouse or alone (as compared to people living with relatives such as parents or siblings).

The study aims to qualitatively analyze how faculty can mobilize the intellectual capital of higher education institutions (HEIs), comprising human, structural and relational capital to enable the education and learning of individuals with intellectual and developmental disabilities.

Drawing upon the extant literature, the researcher conducted a qualitative study through written, in-depth interviews with a sample of 40 academic staff/faculty members having prior experience in teaching individuals with intellectual and developmental disabilities. The data was collected through a set of questions formulated as key questions, to be asked to all participants for their responses.

Results of the analysis demonstrated that intellectual capital’s contribution to higher education of individuals with intellectual and developmental disabilities can be best understood in terms of its three components/dimensions. Accordingly, three main themes, with each comprising two sub-themes were uncovered. The first theme, leveraging human capital comprised: faculty acumen and faculty training as sub-themes; the second theme, resourcing structural capital comprised: tangible and intangible structural capital as sub-themes; and the third theme, nurturing relational capital comprised: in-class engagement and the second is ex-class connection as sub-themes.

The paper collects data from 40 faculty having prior experience in teaching individuals with intellectual and developmental disabilities to explore and reveal a completely new perspective of looking at intellectual capital as a means of providing accessible and inclusive higher education to differently-abled students, making them a part of the mainstream.

This paper examines how developmental risk factors associated with depression in typically developing adolescents may interact with the particular life experience of adolescents with intellectual disabilities and influence vulnerability to depression. We suggest that a consideration of developmental factors and their interaction with the person's social environment may offer a possible framework for prevention and early intervention with adolescents with intellectual disabilities.

In the field of autism spectrum research, there has been a tendency to examine autistics without intellectual disabilities. This focus has come at the expense of examining their peers with intellectual disabilities, who are generally regarded as needing more assistance due to more complex support needs. This chapter begins by defining intellectual disability, followed by an examination of the literature about the prevalence of intellectual disability in the autistic population. The results from the American Government's Centres for Disease Control and Prevention (CDC) Autism and Developmental Monitoring (ADDM) Network about the proportion of autistics with intellectual disabilities are then outlined. Following this, the results from studies about the proportion of autistics with intellectual disabilities are presented. The goal of this section is to show that despite there being evidence that about a quarter of the autistic population have an intellectual disability, this cohort is underrepresented within research about the autism spectrum. Two reasons for this discrepancy are then outlined. This chapter concludes with three suggestions for where more research can be conducted into autistics who have an intellectual disability.

The original contribution that this chapter makes to the field of autism research is to highlight the lack of literature about members of the autistic community who have an intellectual disability as well as presenting several reasons for this lack of research and directions for research in the future.

Many social services today are provided through solutions that require interaction between nonprofits and business. The purpose of this study is to examine the nature of the relationship between the different players in such mixed markets. One such market is workforce integration programs for persons with disabilities. The authors studied the relationships and interactions between collaborating nonprofits and business firms within the context of actor–network theory (ANT) by examining the process of workforce integration.

The study included in-depth interviews and questionnaires with 47 managers of employers that were hiring persons with intellectual and developmental disabilities, as well as in-depth interviews with ten senior managers in five nonprofit organizations involved in work integration of persons with intellectual and developmental disabilities. The interview data were analyzed using qualitative thematic analysis and content analysis.

The authors found an intricate relationship between employers and nonprofits promoting workforce integration. While it seemed that both players were involved in different and complementary aspects and phases of the integration process, the relationship revealed complicated power relations, interdependencies and imbalanced collaborative patterns, resulting in relatively symmetric relations, known as strategic bridging.

Business compliance with workforce integration depends on continued support by nonprofit services.

Findings are essential for promoting workforce integration, and policies need to support the role of nonprofit services.

The study highlights the co-dependence between nonprofits and businesses, contrary to common views that nonprofits are dependent on businesses.

This chapter sought to answer the following questions: (a) what does special education means for students with intellectual disability?, (b) what is being done, and (c) how do we maintain tradition? The answers, while complicated, suggest special education for students with intellectual disability historically and currently involves attention to what, how, and where, with the how being the key elements of special education for students with intellectual disability. This chapter discussed the what, how, and where for students with intellectual disability in a historical and current framework while also providing evidence-based practices for students with intellectual disability to implement to maintain the tradition of high-quality services.

Assistive technology can support and enhance the learning, independence, and daily living skills of students with disabilities, including students with intellectual disability (ID). Assistive technology is not generally disability dependent; however, for students with ID we decided to focus on assistive technology across two areas: instructional aids – with a focus on reading, writing, and mathematics – and transition and independence. Throughout our focus on these two categories of assistive technology, we discuss low-tech, mid-tech, and high-tech options to support students with ID.

The purpose of this paper is to consider the key themes highlighted by Collins et al., in light of the wider research evidence base on informal sources of support for families of children with intellectual and developmental disabilities.

This commentary reflects on the provision of informal support services for families of children with intellectual and developmental disabilities.

The wider literature highlights the key role of family support in shifting negative narratives concerning parenting a child with intellectual and developmental disabilities, the impact of austerity and COVID-19 on support provision and the importance of services working effectively in collaboration to promote self-determination for families and individuals with intellectual and developmental disabilities.

Continued efforts to explore how services and informal social supports might work together in an effective manner are key to improving the quality of life of parents caring for children with intellectual and developmental disabilities.

In this paper, the authors summarize the empirical and theoretical gaps in understanding of police contact with individuals with intellectual and/or developmental disabilities at the individual, interactional, organizational and systems level and introduce the special issue papers which address these gaps. The authors close with a discussion of future directions for research in this area.

The authors’ objective in producing this issue was to create a platform to generate and facilitate research in this area. The authors chose papers that represented research that could “move the needle” around the understanding of policing and intellectual and/or developmental disabilities.

The papers in this special issue reflect four thematic areas: (1) the nature of interactions between the police and individuals with intellectual and/or developmental disabilities; (2) police interactions about individuals with intellectual and/or developmental disabilities with criminal justice systems, social services and mental health services, (3) experiences of the police when encountering individuals with intellectual and/or developmental disabilities and finally, (4) the experiences within police encounters of individuals with intellectual and/or developmental disabilities.

Research on intellectual and/or developmental disabilities is still in its infancy, particularly within the field of criminology and criminal justice. This special issue brings together innovative international research that adds critical information surrounding the nature of interactions between the police and individuals with intellectual and/or developmental disabilities, the experience for both parties during that interaction and the context of these interactions in the larger organizational ecosystem of criminal justice organizations and social service agencies.

This chapter reviews the intervention research literature – particularly interventions deemed evidence-based – for students with intellectual disability across academic and life-skills instruction. Although the focus of this chapter is the spectrum of students covered under the term “intellectual disability,” the majority of research on evidence-based interventions for students with intellectual disability focus on students with more moderate and severe intellectual disability, rather than students with mild intellectual disability. The majority of the interventions determined to be evidence-based within the literature for students with intellectual disability – across both academic and life skills – tend to be those that fall within the purview of systematic instruction.
