Quizplus · Accepted Answer

The A-B design does not control for the effect of confounding variables. This design only measures the behavior before and after the intervention without comparing it to a control group or baseline. It is not possible to rule out the influence of other variables that may have affected the behavior change. The other designs listed (A-B-A-B, changing-criterion, and multiple-baseline) all have some form of control for confounding variables.
