What is ABAB reversal design?

Answer 1

A-B-A-B Reversal Design refers to a type of singlecase experimental design in which a Baseline ofBehavior 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.

Answer 2

ABAB reversal design is a type of single-case research design where the intervention is alternated on and off to evaluate its effects. The design involves two baseline phases (A), an intervention phase (B), and then a return to baseline (A) to assess whether changes observed during the intervention were due to the intervention itself.
