What is an ABAB design?
The A-B-A-B design represents an attempt to measure a baseline (the first A), a treatment measurement (the first B), the withdrawal of treatment (the second A), and the re-introduction of treatment (the second B). The initial A in this design refers to a baseline for each subject.
Why is an ABAB design preferable to an ABA design?
The ABAB design is superior to the ABA design because a single reversal is not strong enough for the effectiveness of the treatment. to demonstrate effectiveness of the treatment, a change must be observed under multiple circumstances to rule out the possibility that other events are responsible.
What are the advantages of an ABAB design?
ABAB designs have the benefit of an additional demonstration of experimental control with the reimplementation of the intervention. Additionally, many clinicians/educators prefer the ABAB design because the investigation ends with a treatment phase rather than the absence of an intervention.
What is the difference between ABA design and ABAB design?
So, in the ABA model, the initial behavior is altered by the intervention and then the intervention is withdrawn to see if the behavior returns to the baseline level. The ABAB form of the method is the reintroduction of the intervention after the return to the baseline to judge the strength of the intervention.
What is an ABA reversal design?
an experimental design, generally used when only a single group is being studied, that attempts to counteract the confounding effects (see confound) of sequence and treatment by alternating baseline conditions with treatment conditions. Examples include the A-B-A design and other similar combinations.
When would you use a reversal design ABA?
What is another name for ABAB design?
Withdrawal designs, also known as ABAB designs, rely on the comparisons between conditions when an intervention is in place and conditions when that intervention is not being implemented.
When should a reversal design not be used?
One should not use a reversal design with behaviors that are not reversible. For instance, if you teach a person to fish, that individual is not likely to forget how to fish, making a reversal design a poor choice for evaluating your fishing intervention.
