ABSTRACT
This article examines single-case designs that omit baseline phases, contain shorter reversal phases, administer treatment across fewer baselines, or have other features that make them easier for practitioners to use in evaluating their own interventions. Particular attention is given to the Repeated Pretest-Posttest and the Periodic Treatments Designs, the Nonconcurrent Multiple-Baseline Design, the short reversal design, the short multiple-baseline design, and the short alternating treatments design. Also discussed and illustrated is how these streamlined designs can raise practitioners' sensitivity to intervention outcomes, assist practitioners in providing evidence-based services while adjusting for client diversity, and advance practitioners' knowledge.
