NettetReversal Designs. The most basic single-subject research design is the. reversal design. , also called the ABA design. During the first phase, A, a. baseline. is established for the dependent variable. This is the level of responding before any treatment is introduced, and therefore the baseline phase is a kind of control condition.

Nettet1 Reversal or ABAB design. The reversal design demonstrates the effect of the intervention by alternating the presentation and removal of the program over time. The purpose of the design is to demonstrate a functional relationship between the target behavior and the intervention. NettetThe ABAB Withdrawal design’s limitations include all of the following except: a) potential ethical concerns for withdrawing treatment for target behaviors b) it can’t be used with non-reversible behaviors c ) resentment by participants for withdrawing treatment d) it controls for many threats to internal validity NettetFigure 4.2 shows the application of the ABABA design on three subjects each being applied a different treatment. From the chart it is obvious that treatment 1 increases the desired behavior but that this behavior returns quickly to baseline when the treatment is discontinued. Treatment 2 shows no change in behavior in any of the trials. durham charity fashion show
