A-B-A-B Reversal Design refers to a type of singlecase experimental design in which a Baseline of Behavior is first taken (A), followed by an Intervention phase (B), then a return to baseline phase where the intervention is removed (A), and a final phase in which the intervention is reintroduced (B). When changes in behavior occur only during the intervention phases, this provides evidence that changes in behavior are due to the intervention.
