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 annual survey of more than 20,000 nationally representative people with IDD, we fit a series of classification tree and random forest models to predict individuals' employment status and day activity participation as a function of their responses to all other items on the 2017-2018 NCI-IPS. The most accurate model, a random forest classifier, predicted employment outcomes of adults with IDD with an accuracy of 89 percent on the testing sample, and 80 percent on the holdout sample. The most important variable in this prediction was whether or not community employment was a goal in this person's service plan. These results suggest the potential machine learning tools to examine other valued outcomes used in evidence-based policy making to support people with IDD.

Researchers and advocates have long called for improved research methods that better include people with intellectual and developmental disabilities (IDD), but challenges to doing so persist. Proxy responses are frequently used to circumvent some of these challenges, but may not fully capture the perspectives of people with IDD. The COVID-19 pandemic highlighted the possibility of consequences due to a lack of research about health outcomes for people with IDD, with documented disproportionate impact but little understanding about specific experiences for people with IDD. Using exploratory graph analysis (EGA) we explored the use of proxy responses on the COVID-19 Supplement of the National Core Indicators In-Person Survey. Findings suggest significant differences in response patterns between people who answered independently, via proxy, and with a mix of response types beyond what would be expected due to demographic differences in participants.

Having a sense of social inclusion and belonging, typically characterized by our personal relationships and community participation, is the central essence of life for most people, yet it remains elusive for many people with intellectual and developmental disabilities (IDD). This article summarizes the work of a diverse group of researchers and advocates to propose 6 big-picture, equity-based goals to drive future research in the field: (1) understanding the role of intersectionality, (2) understanding intimate relationships, (3) promoting formation of communities of care to support social inclusion, (4) understanding life course trajectories of social inclusion, (5) understanding social inclusion in virtual spaces, and (6) understanding how to promote social inclusion in the entire research process.

Objective: In the United States, people with intellectual and developmental disabilities (IDD) vote at significantly lower rates than people without disabilities and are underrepresented in the democratic process. This paper examines predictors of voting opportunity among people with IDD receiving state-funded disability services in Virginia. Method: We used secondary data from Virginia's 2017–2018 and 2018–2019 National Core Indicators In-Person Survey to conduct bivariate and regression analyses on possible predictors of voting opportunity identified from the literature. Results: Factors related to level of intellectual disability were significantly associated with having voting opportunity, as were several factors related to exercising other rights, including participating in the community and in self-advocacy training. Importantly, respondents who had participated in self-advocacy events were more likely to have voting opportunity and people with guardians were less likely to vote or to have had the opportunity. Conclusion: People with legal guardians may be the most likely to be excluded from the democratic process. Social workers and advocates seeking to increase voter turnout should strive to include people with more severe disabilities in self-advocacy events and other efforts to increase voting opportunity among people with IDD.

BACKGROUND: People with intellectual and developmental disabilities (IDD) tend to have poor employment outcomes relative to the general population, as do people with autism. Research is unclear, however, about how people with IDD with and without autism compare on a variety of employment-related indicators, including desire to work, having work as a goal in their service plans, and being employed. OBJECTIVE: To understand how people with IDD with and without autism compare on important employment-related outcomes, based on a matched random sample. METHODS: Using merged administrative datasets, we used propensity score matching to construct statistically proximate samples of Medicaid waiver users in a single state with IDD both with and without autism, and then tested differences between the two groups on important employment-related indicators. RESULTS: People with IDD and autism were less likely than people with IDD alone to have a goal for employment in their individualized service plans and to hold employment in group community settings. There was no statistical difference between the two groups in terms of desire to have a job or employment in individual community settings. CONCLUSION: Results reinforce the importance of planning for employment if holding employment is a person's aim, regardless of the presence of autism. [ABSTRACT FROM AUTHOR]

People with intellectual and developmental disabilities (IDD) may be at an increased risk of severe illness and death from COVID-19. This article examines the role of information and knowledge in COVID-19 vaccine uptake for people with IDD and their families. We developed a survey about COVID-19 vaccine uptake, confidence, and knowledge for people with IDD and their families. COVID-19 vaccine uptake was associated with higher self-reported knowledge about the vaccine, learning about the vaccine from one's doctor, and social media use. Qualitative results reflected the importance of trusted relationships with medical providers in vaccination. [ABSTRACT FROM AUTHOR]

Researchers used a merged dataset to examine if more resources were expended on those with greater support needs and if support needs impacted personal outcomes when controlling for relevant personal and contextual factors. Results indicated that the amount of support a person receives had a direct relationship to their needs. However, we also found that people with the greatest needs had weaker personal outcomes suggesting that distribution of resources based on need may not result in equivalent outcomes. The authors suggest strategies at an individual and systems level to address the outcomes gap for people with the greatest support needs. [ABSTRACT FROM AUTHOR]

This study tests an empirically derived model for measuring personal opportunities for people with intellectual and developmental disabilities (IDD) using National Core Indicators In-Person Survey (NCI-IPS) state and national datasets. The four personal opportunities measured, (a) privacy rights, (b) everyday choice, (c) community participation, and (d) expanded friendships, were informed by existing conceptualizations of service as well as NCI-IPS measures. Analyses confirmed the fit of a four-factor model and demonstrated that factors were significantly and positively correlated. To demonstrate the relationships between personal opportunities and personal and environmental characteristics, we estimated a structural equation model that regressed personal opportunities on age, gender, place of residence, and level of intellectual disability. Implications for using personal opportunities for evaluating service quality of IDD systems are discussed. [ABSTRACT FROM AUTHOR]

Clostridium perfringens is one of the etiologic agents of gas gangrene that can occur when a wound is contaminated with soil. Type A C. perfringens can cause foodborne and nonfoodborne gastrointestinal illnesses due to an enterotoxin (CPE) produced by some strains during sporulation. We developed a quantitative real-time PCR assay based on fluorescence resonance energy transfer hybridization chemistry that targets the C. perfringens-specific phospholipase C (plc) gene and the enterotoxigenic gene (cpe) with the LightCycler and the Ruggedized Advanced Pathogen Identification Device (R.A.P.I.D.). The assay can detect as few as 20 copies of target sequences per PCR. The total assay time, from extraction to PCR analysis, is 90 mm. This assay is rapid, sensitive, and specific and will allow direct detection of C. perfringens in water, food, and stool samples. It should prove helpful in investigating foodborne illnesses due to C. perfringens and can be used as a tool to ensure the safety of food and water supplies. [ABSTRACT FROM AUTHOR]

BackgroundMethodsFindingsConclusionsAdults with intellectual and developmental disabilities (IDD) often have behavioral support needs that must be met in order to live in community settings. Pharmacotherapies are often used to meet such needs. We explored factors that predict medication for behavioral support among adults with IDD.We integrated three major U.S.- based IDD-specific datasets over multiple years, creating a large dataset. We used machine learning to build and test an algorithm to predict factors associated with the use of pharmacotherapies to address behavioral support needs for adults with IDD.Our algorithm correctly predicted the use of pharmacotherapies with about 79% accuracy. Top predictors of medication use to address behavioral support needs included disruptive behavior, use of medication to treat a mental health condition, and presence of an autism diagnosis.Use of behavior plans should be given more attention in conjunction with medication use, especially in relation to managing disruptive behavior.

Medicaid Home and Community-Based Services (HCBS) for people with intellectual and developmental disabilities (IDD) are vital for supporting people with IDD to live well in their communities, but there are not set standards for monitoring quality outcomes related to HCBS. In this paper, we propose promising practices for improving the quality of HCBS outcome measurement, based both in the literature and our own experience conducting an extensive U.S. state-level study. Specifically, we discuss: (1) using merged administrative datasets, (2) developing high-quality psychometrics that attend to ecological issues in measurement, (3) using advanced statistical analyses, and (4) creating immersive, user-friendly translational dissemination products. We conclude by suggesting what we see as important new frontiers for researchers to consider in order to enhance the quality of HCBS outcome measurement for people with IDD in the future., Competing Interests: Conflict of Interest: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest.

Background and Purpose: People with intellectual and developmental disabilities (IDD) often have health and wellness issues that are not as good as people without disabilities. States are required to monitor health and wellness for people with IDD who use many disability services. However, there are few ways to monitor wellness between states or at different points in time. In this study, we share a new model that states may use to monitor wellness of people with IDD., Methods: We used data from a survey called the National Core Indicators (NCI) to develop this model. First, we developed the model using our state's data. Then, after we found a model that worked well, we tested that model using the National Core Indicators from the entire U.S., Results: Our final model worked well in both our state NCI data and the national NCI data. This is important because policies at both levels can affect the services that people with disabilities can use. Our model had three parts: heart health, mental health, and behavioral wellness. These are described more in the paper. We also used statistics to test some factors that might predict outcomes related to heart health, mental health, and behavioral wellness. Age, sex, where someone lives, and level of intellectual disability were all good predictors of all three categories of wellness that we studied., Implications: The model of wellness that we developed worked well but should be tested using data from other individual states. It is very important to know about health and wellness right now since the services people with disabilities can use are changing in many states. We think our model can help planners and advocates understand how services affect wellness in a way that is easy to compare from state to state and at different points in time.
