Question

Quizplus · Accepted Answer

The ABAB design involves a repeated reversal of the treatment. Therefore, it is best-suited for treatments that have an immediate but temporary effect. This way, the researcher can observe the effects of the treatment during the treatment phase and compare it to the baseline phase. If there is a significant change from baseline to treatment phase, and then the change reverts back to baseline during the withdrawal phase, it suggests that the treatment was effective in producing the observed change. If the treatment had a permanent effect, there would be no need for a withdrawal phase, and the treatment would not need to be reversed. If the treatment had a very delayed effect or a coincidence long-lasting effect, it may be difficult to observe the effects during the treatment phase and withdrawal phase of the ABAB design.
