Compare and contrast withdrawal designs (e.g., A–B–A; A–B–A–B) with concurrent multiple baseline designs.
What will be an ideal response?
Ans: Varies.
A–B–A designs include a period of measurement after the intervention has been given in which the intervention is stopped. The idea behind this design is that if the intervention works, scores should worsen when it is removed. In practice, this design poses ethical problems. Further, many therapeutic treatments are designed to help people even after the intervention has ceased. Concurrent multiple baseline designs are also a type of single-subject design, but it addresses the problem of withdrawal in A–B–A designs by incorporating additional subjects, target problems, or settings to the study. They use a series of A–B designs that begin at the same time, but the length of the baseline period is staggered. This effectively helps control for external events.
