Disadvantages of ABAB Design
The main disadvantages of the ABAB design are ethically based. For example, withdrawing treatment could pose issues depending on the seriousness of the specific targeted behaviors involved. For example, withdrawing a treatment that markedly reduces serious self-harm in a child might be seen as unethical and unnecessary. Therefore, in some cases, it is impossible to use a reversal period. Ethical concerns can also arise in research settings where therapists may be unwilling to have their clients re-experience situations that could reinstate the very behaviors they are seeking to eradicate.

ABAB Reversal Design Example
Arrange the phases of an ABAB research design in their correct chronological order.
A researcher uses an ABAB design to test whether a relaxation technique reduces anxiety in a client. During the first treatment phase, the client's anxiety decreases. When the treatment is temporarily removed, anxiety increases again. The treatment is then reintroduced and anxiety decreases once more. What is the primary reason the researcher includes the final treatment phase rather than ending the study after the return-to-baseline phase?
