Toward Accountability in Supervision: A Single‐Case Illustration

This article illustrates the potential of a single‐case research design as a method for demonstrating supervisor accountability. A supervisor in training employed a multiple baseline design to evaluate the effectiveness of a brief supervisory intervention. The targeted counselor behaviors were a decrease in the use of questions and an increase in reflections of feelings. The intervention consisted of counselor self‐monitoring and supervisor reinforcement. The data showed marked decreases in counselor questioning, accompanied by increases in reflections of feeling. Concomitant changes in client behavior included more active participation in the session and more frequent discussion of feelings. The decrease in counselor questions was stable over a follow‐up period. The process and decisions involved in using a single‐case design to evaluate supervisor effectiveness are discussed.
