Data about IDD and Health

People with IDD in Research

Another explanation for critical gaps in research and understanding of people with IDD has to do with the exclusion of people with IDD from research studies. This exclusion is attributed to several factors, including the relatively small population size of people with IDD, historical lack of power and influence among this group, concerns about exploitation and vulnerability in research settings, overly cautious ethics committees, assumptions about inability to provide informed consent, and inaccessible study materials and processes.

The impact of this exclusion is significant and far-reaching. It denies people with IDD the opportunity to contribute to scientific knowledge and ensures that research findings may not be applicable to this population. Furthermore, it results in a lack of data on the health and well-being of people with IDD, making it difficult to identify and address issues uniquely affecting this group. This underrepresentation ultimately perpetuates health disparities and limits our scientific understanding of people with IDD.

Recommendations for increasing the inclusion of people with IDD in research

Inclusive research approaches are on the rise and help create studies that better represent and serve the IDD community and advance overall scientific knowledge.

Recommendations for inclusive research include:

  • Adapting research materials and processes for accessibility,  
  • Using plain language and simplified consent procedures,  
  • Offering individualized accommodations and supports, building community partnerships with IDD organizations, and  
  • Including people with IDD in leadership roles throughout the research process.  

Further, it is vitally important to consider the capacity for people with IDD to consent to participating in research, which can be addressed through tailored questions, developing flexible recruitment strategies, and involving people with IDD at all stages of the research process.

Projects Implementing Inclusive Research

RTI: Nothing About Us Without Us

RTI describes three equity-based principles informed by our work on equity centered research for a community historically excluded from and overlooked in research: representation, engagement, and leveraging assets.

Waisman Center, University of Wisconsin-Madison

The Ausderau Lab at the University of Wisconsin-Madison Waisman Center developed the READI (Research Engagement and Advocacy for Diverse Individuals) curriculum. It is a guide for individuals with IDD and their caregivers to understand and get involved in research as participants, researchers, and consumers.

Special Olympics Project ALL STAR

Project ALL STAR aims to understand how Special Olympics programs improve athletes' lives. This evaluation project looks at how Special Olympics programs affect athletes. It studies their health and well-being over time. It seeks to identify lasting impacts on their physical, social-emotional, and mental health.

University of Illinois Chicago and Special Olympics Illinois

Dr. Lieke van Heumen, a faculty member in the Department of Disability and Human Development at University of Illinois Chicago (UIC), and Courtney, an Athlete Leader and Health Messenger at Special Olympics Illinois, have formed a dynamic partnership that has impacted the field of disability studies.

National Council on Disability: The Implicit and Explicit Exclusion of People with Disabilities in Clinical Trials

Sixty one million Americans, or 26% of U.S. adults, live with a disability and are routinely excluded from clinical trials, thereby limiting their access to life-changing or even life-saving healthcare resources.
