Differing Understandings of Informed Consent Held by Research Institutions, People with Intellectual Disability, and Guardians
Increasing participation of people with intellectual disability (ID) is necessary for inclusive, ethical research that reduces persistent disparities in representation. However, many adults with ID have guardians, who must consent to research involvement. Researchers have found that guardians are less likely to provide consent than the person with ID, often resulting in lower participation. Institutional Review Board (IRB) members also have been found to hold very cautious views regarding research participation compared to the views of people with ID or their guardians. This chapter reviews issues that emerge because of differing views of research participation held by IRB members, guardians, and people with ID that may unnecessarily limit the participation of people with ID in research. The research literature on these barriers is summarized along with the authors’ own experiences with alternative participatory strategies that have the potential to increase both self-determination and participation in research for people with ID.
