The Use of Single-Subject Design in Rehabilitation Counseling Research
BackgroundThe utility of single-subject designs as a practical methodology for rehabilitation professionals working in the field and one that allows researchers the flexibility to identify or change treatments in the event their participant or client is not responding has been established for nearly a century (Dixon, 2002). However, a content analysis of the presence of single-subject research in rehabilitation research has been absent from the rehabilitation literature.PurposeThe purpose of this article is to describe the usability of single study designs as a research tool that contributes to the identification of Evidence-Based Practices (EBPs) in rehabilitation counseling.MethodsThrough manual and electronic searches of the literature, the authors identified journals and subsequently articles that clearly stated the use of single-subject design as their method of data collection and analysis.ResultsBetween 2001 to 2016, there have been a total of eight articles published that have either utilized single-subject experimental designs or provided an overview of the methods.ConclusionsA critical review of the rehabilitation literature indicated that single-subject methodologies have been recognized as contributing to the identification of EBPs, yet studies utilizing a single-subject methodology continue to be rare. The paucity of single-subject design may be the result of a lack of training opportunities, lack of models in the rehabilitation literature, and assumptions that single-subject design utility is limited to behavioral research.
