There is a paucity of explicit literature outlining methods for single-interview studies with children, and almost none have focused on engaging children with disabilities. Drawing from a pilot study, we address these gaps by describing innovative techniques, strategies, and methods for engaging children and youth with disabilities in a single qualitative interview. In the study, we explored the beliefs, assumptions, and experiences of children and youth with cerebral palsy and their parents regarding the importance of walking. We describe three key aspects of our child-interview methodological approach: collaboration with parents, a toolkit of customizable interview techniques, and strategies to consider the power differential inherent in child-researcher interactions. Examples from our research illustrate what worked well and what was less successful. Researchers can optimize single interviews with children with disabilities by collaborating with family members and by preparing a toolkit of customizable interview techniques.
