Background: Inclusive research is increasingly common in intellectual disabilities research, but ways in which voice of co-researchers with intellectual disabilities is presented remain underexplored in the literature. Materials and Method: The authors conducted a literature review and analysis of peer-reviewed journal articles reporting on inclusive research. The aim was to explore the ways the voices of co-researchers with intellectual disabilities are represented in published peer-reviewed journal articles. Results: The findings indicate that there are a wide range of ways in which inclusive research projects are reported in peer-reviewed journals. However, the experiences, views and opinions of co-researchers are often either absent or very selectively reported. Conclusions: The article concludes that although inclusive research has proliferated in the 21st century, more attention needs to be paid to the ways in which the voices of co-researchers with intellectual disabilities are heard in formal academic contexts. Guidelines for future practice are offered.
