A multiple-baseline across participants design involves measuring the baseline behavior of multiple participants and then introducing the independent variable at different times across the participants to see if the behavior changes. This design is useful when it is not ethical or practical to withdraw the treatment, which is a requirement for the reversal design. The pretest/posttest design only measures behavior before and after the introduction of the independent variable and does not involve measuring baseline behavior. The multiple-baseline across time design involves measuring the same behavior at different times during baseline before introducing the independent variable.
