D.7. Distinguish among reversal, multiple-baseline, multielement, and changing-criterion designs.
Designed for BCBA candidates, practicing clinicians, and graduate students, this post clarifies how to distinguish among reversal, multiple-baseline, multielement, and changing-criterion designs. It explains what each design demonstrates about experimental control, when to use it, and how to avoid common pitfalls that threaten ethics or validity. The focus is on turning ABA data into clear, ethical decisions about intervention effects for real clients.
