title: The repeated pretest-posttest single-subject experiment: a new design for empirical clinical practice.
abstract: The logic of a new design for empirical clinical practice, the repeated pretest-posttest experiment, is described. This design is readily applicable by individual practitioners in the human services, possesses high internal validity, and presents minimal intrusiveness into the delivery of service. A single-case study is used to illustrate the application of the repeated pretest-posttest experiment in clinical research.
