Document Summary

Staggered application: the procedure continues in sequence until the intervention has been, experimental control is demonstrated when application of the intervention changes the current behavior, but the rate of other (untreated) behaviors remain stable, the effects of a treatment are inferred from untreated behaviors, less internally valid than the reversal design, because the controlling effects of the intervention on each behavior are not demonstrated. Variations of the multiple baseline design: multiple baseline across behaviors, evaluates the effects of the same intervention across different behaviors, advantages, return to baseline is not necessary to demonstrate experimental control, lends itself to intervention evaluation in the natural setting, disadvantages, at least three behaviors must be identified, concurrent measurements of multiple baselines can be complex. Variations of the multiple baseline design: multiple baseline across subjects, advantage, well suited for classroom use, disadvantages, a minimum of three similar individuals must be identified, may be time consuming and impractical.
