Social researchers and participants with intellectual disabilities and complex communication access needs: Whose capacity? Whose competence?

Despite the evolution of inclusive research and augmentative and alternative communication, there is an ongoing absence of people with intellectual disabilities and complex communication (access) needs from sociological cohorts. In an in-depth study of 10 individuals with complex communication access needs, the involvement of three participants with intellectual disabilities was highlighted. The purpose of this article is to describe how the investigation was conceptualised, designed, and adapted to maximise the participation of adults with intellectual disabilities and complex communication access needs.
