The purpose of this article is to encourage the use of single-case research designs by researchers and clinicians studying communication disorders, especially those studying orofacial disorders. Our encouragement is based on the current need for rigorous, intervention research focusing on intervention strategies for children who have acquired dysfunctional speech patterns. Research is needed that not only identifies improvement in child behavior, but documents the clinical mechanism(s) responsible for that improvement. Traditional group design research is one powerful and effective approach for addressing key research questions, but group designs are less feasible when studying the clinical challenges of a small, geographically distributed population. Children with cleft palate, for example, represent a small percentage of the population and are widely distributed geographically. The physical challenges faced when constructing group design studies with these children are daunting in all but the most densely populated areas.
