Why is an ABAB reversal design better than an ABA reversal design?

Solution

•Repeated measures of behavior occur in a given setting

•Requires at least 3 consecutive phases:

•Initial baseline (A)

•Intervention (B)

•Return to baseline (A)

•Is preferred over A-B-A as stronger demonstration

•Very powerful non-experimental within-subject design

•Can strongly demonstrate a functional relation between an environmental manipulation and a behavior
