Guidelines for the Creation of Accessible Consent Materials and Procedures: Lessons from Research with Autistic...

Informed, voluntary, ongoing consent is a central tenet of ethical research. However, consent processes are prone to exclusionary practices and inaccessibility. Consent materials are often too long and complex to foster understanding and ensure that people make truly informed decisions to participate in research. While this complexity is problematic for all people, these challenges are compounded for autistic people and people with intellectual disability. Consent materials and procedures rarely incorporate accommodations for processing and communication differences common in autism and intellectual disability. Failure to provide such accommodations ultimately threatens the conduct of ethical research. We describe lessons learned across multiple major U.S. research institutions that improved informed consent materials and procedures, with the goal of fostering responsible inclusion in research for autistic people and people with intellectual disability. We used these alternative materials and procedures in multiple research projects with samples of autistic people and people with intellectual disability. Each contributing team partnered with university human research participant protections personnel, accessibility experts, community members, and researchers to develop rigorous procedures for improving the readability and accessibility of informed consent materials. We present guidelines for designing consent materials and procedures and assert that participatory methods are vital to the success of ongoing accessibility initiatives. Adoption of understandable consent materials and accessible consent procedures can cultivate more equitable, respectful, and inclusive human research practices. Future work should expand on this work to design inclusive practices for populations with additional considerations.
