© The Author(s) 2017. Researchers are challenged to provide opportunities for people with intellectual disabilities (IDs) and their families to become participants in research. This article explores the processes and procedures involved in conducting a mixed-methods study. The preparation for the study is described and explained. Recruitment is examined by describing the process and analysing phone calls made to potential participants. Reflections of research team members help to develop the analysis and contribute to a discussion of the fieldwork. Lessons learned show that research projects involving people with IDs and their families need careful planning and have additional costs. The research team requires a mix of expertise. Traditional recruitment methods may not be suitable, and researchers need to build good relationships with gatekeepers so that participants can be contacted directly. Good quality research with people with IDs and their families is possible once suitable strategies are employed throughout the research process.
