Identifying Predictors for Enhanced Outcomes for People With Intellectual and Developmental Disabilities

Outcomes for Adults With Intellectual and Developmental Disabilities Receiving Long-Term Services and Supports: A Systematic Review of the Literature

The impact of long-term services and supports on the quality of life of adults with intellectual and developmental disabilities (IDD) is not well understood given the highly complex nature of researching this topic. To support future research addressing this topic, we conducted a systematic literature review of studies addressing outcomes of adults with IDD receiving long-term services and supports. Results of this review describe current outcomes for adults with IDD who receive long-term services and supports and can be used to inform program evaluation, policy development, and future research.

Co-Occurring Mental Illness and Behavioral Support Needs in Adults with Intellectual and Developmental Disabilities

People with intellectual and developmental disabilities (IDD) have higher incidences of mental health conditions and behavioral support needs than people without IDD but may not receive needed care from community providers. We examined rates of co-occurring conditions in a representative sample of adults with IDD who use state funded services in Virginia. Using data from two datasets, we identified four categories of mental health and behavioral conditions. We used these categories to examine differences in individual- and system-level factors in people with and without co-occurring conditions. We found high rates of co-occurring conditions in our sample. We found important disability factors and system-level characteristics that were associated with having a diagnosed mental health condition or behavioral support needs. Differing patterns of diagnosis and treatment for co-occurring conditions suggests more work needs to be done to support people with IDD and co-occurring mental health conditions living in the community.

An Examination of Support Needs, Supports, and Outcomes for People With Intellectual and Developmental Disabilities

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.

Professional Responsibility in the Field of Intellectual and Developmental Disabilities: Its Definition, Application, and Impacts

This article addresses the need to clearly understand professional responsibility and the critical role it plays in the lives of individuals with intellectual and developmental disabilities (IDD), in shaping professions for the better, and in enhancing the functioning of society for the benefit of all. Understanding professional responsibility is especially timely during the current transformation that is occurring in the field of IDD. To that end, the article discusses what is a profession, who is a professional, and what is professional responsibility. Using a logic model framework, the article describes the components of professional responsibility that include its building blocks such as respect for the person, professional ethics and standards, critical thinking skills, and clinical judgment; its use of nine professional practices including empowerment, evidence-based practices, individualized supports, and person-centered outcome evaluation; its outcomes in terms of mutual trust, the improved effectiveness of clinical functions, and professional accountability; and its impacts regarding individual benefit, professional integrity, and societal enhancement.

Promising Practices in the Frontiers of Quality Outcome Measurement for Intellectual and Developmental Disability Services

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.

The impact of competitive integrated employment on economic, psychological, and physical health outcomes for individuals with intellectual and developmental disabilities

BACKGROUND

Although competitive integrated employment (CIE) has been established as a goal of employment research, policy, and practice for individuals with intellectual and developmental disabilities, the secondary benefits of CIE are rarely discussed.

AIMS

The purpose of this systematic review was to analyze and synthesise research related to the association between CIE and improved economic, psychological health, and physical health outcomes for individuals with intellectual and developmental disabilities.

MATERIALS & METHODS

Our review searched peer-reviewed literature from seven electronic databases and screened 1110 peer-reviewed articles based on inclusion criteria established following PRISMA guidelines.

RESULTS

Our search procedures produced a final sample of 17 studies.

DISCUSSION

Implications of these findings for future research, policy, and practice are provided.

CONCLUSION

Our findings showed strong evidence associated with economic outcomes of CIE, moderate associated with psychological health outcomes, and limited evidence related to physical health outcomes.

Measuring Four Personal Opportunities for Adults With Intellectual and Developmental Disabilities

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.

Using Machine Learning to Predict Patterns of Employment and Day Program Participation

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.

Ongoing Transformation in the Field of Intellectual and Developmental Disabilities: Taking Action for Future Progress

There has been a significant transformation in the field of intellectual and developmental disabilities (IDD) over the last 5 decades. Although this transformation has profoundly influenced multiple stakeholders, the field is currently at a critical juncture and facing a number of social and political challenges. Given the relevance of the question, "where is the field of IDD and where do we go," the present article describes the field's transformation, and suggests future action steps to facilitate and sustain the transformation. The seven action steps discussed in the article relate to using precise terminology, incorporating a functional and holistic approach to IDD, embracing the supports model and evidence-based practices, implementing outcome evaluation, empowering individuals and families, understanding better the multidimensional properties of context, and incorporating an explicit notion of professional responsibility.

Enhancing research practices in intellectual and developmental disabilities through person-centered outcome evaluation

BACKGROUND

Research practices in IDD need to align current values towards people with IDD, the current understanding of IDD, and best practices regarding change strategies and valued outcomes.

AIMS

To describe the components to-and application of-a person-centered outcome evaluation model that meets the above criteria.

METHODS AND PROCEDURES

A person-centered evaluation logic model is used to identify and describe a conceptual framework (input), a change strategy (throughput), personal outcomes (outcome), and meaningful impacts (output).

OUTCOMES AND RESULTS

Specific person-centered outcomes and exemplary outcome indicators are presented for two outcome evaluation frameworks: human functioning dimensions, and the four theoretical perspectives on IDD: biomedical, psychoeducational, sociocultural, and justice.

CONCLUSIONS AND IMPLICATIONS

A person-centered approach to outcome evaluation enhances research practices in IDD by identifying and assessing valued personal outcomes that align current values, understanding, and best practices; increases transparency; facilitates accountability; and expands understanding.

Testing a Wellness Indicators Measure for People with Intellectual and Developmental Disabilitiesa

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.

A Systematic Review of the Assessment of Support Needs in People with Intellectual and Developmental Disabilities

An evaluation of support needs is fundamental to the provision of services to people with intellectual and developmental disabilities. Services should be organized by considering the support that people need to improve their quality of life and enforce their rights as citizens. This systematic review is conducted to analyze the rigor and usefulness of the available standardized tools for assessing support needs, as well as the uses of their results. Several databases were consulted, including Web of Sciences, Scopus, PubMed, ProQuest Central, PsycInfo, ERIC, and CINAHL, and the 86 documents that met the review criteria were organized into four sections: (a) measurement tools, (b) descriptive/correlational studies, (c) predictive studies, and (d) interventions. The results showed that age, level of intellectual disability, adaptive behavior skills, the number and type of associated disabilities, and medical and behavioral needs affected the support needs of people with disabilities. Quality of life outcomes have been predicted by the individual's support needs, explaining a significant percentage of their variability. The findings are useful in guiding assessments and planning interventions. Further research should address the effectiveness of specific support strategies and the development of social policies and indicators for inclusion that involve assessing support needs.
