Both a multiple-baseline-across-persons design and a changing-criterion design can establish cause-and-effect relationships without requiring a reversal to baseline. Multiple-baseline designs demonstrate effects by showing that changes only occur when and where the intervention is applied, across different subjects, settings, or behaviors. Changing-criterion designs demonstrate effects by systematically altering the criterion for reinforcement or intervention and showing that behavior changes to match the new criteria.
