The ABAB single-subject research design involves a sequence of baselines (A) followed by an intervention (B), then a return to baseline (A), and finally a return to intervention (B). This allows for both the effectiveness of the intervention and the reversibility of its effects to be demonstrated. The ABA design also uses baselines and interventions, but does not include a return to intervention phase. The AB design only includes a baseline and intervention phase, without any returning to baseline or intervention.
