The ABAB design involves measuring the behavior of interest before the treatment is introduced, so that any changes can be accurately attributed to the treatment. This step is typically referred to as the “A” phase. The subsequent phases involve introducing the treatment (“B” phase) and then removing it (“A” phase again) to see if the behavior returns to its original level or maintains the changes produced by the treatment. Therefore, the first step in the ABAB design is measuring the behavior of interest before the treatment (i.e., the first “A” phase).
