A study highlighted the challenges of including adults with intellectual and developmental disabilities in general population research. Interviews with 25 research team members identified several barriers to inclusive recruitment. These obstacles included direct and indirect exclusionary practices, insufficient knowledge and skills among researchers, reliance on temporary accommodations, and the belief that participation from this group lacks scientific value. Additionally, there were misconceptions about the willingness and ability of individuals with intellectual disabilities to engage in research. Despite these challenges, research team members expressed a strong interest in learning how to better include this population in studies. The findings emphasize the need for improved strategies to ensure diverse participation in research, which is essential for fair distribution of benefits and burdens across different patient groups.
