What is an ABAB design in psychology?
An ABAB research design, also called a withdrawal or reversal design, is used to determine if an intervention is effective in changing the behavior of a participant. The design has four phases denoted by A1, B1, A2, and B2. In each phase, repeated measurements of the participant’s behavior are obtained.
What is an example of 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). As a simple example how this design might work, imagine you just adopted two untrained puppies.
Which design is better an ABA design or an ABAB design?
A reversal design aims to establish the reversibility of the manipulation of the independent variable. An ABAB design is superior to an ABA design because it shows two problems with the reversal design; one that the treatment may not be efficiently powerful evidence for the effectiveness of treatment.
Why researcher should consider an ABAB design over the ABA design?
Why is an ABAB design superior 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. Also the sequence ends with the treatment rather than with people withdrawing from the treatment.
What is another name for an 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.
How do you use ABAB design?

When would you use an ABAB design?
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.
When might it be most appropriate to use ABAB design?
Sometimes an individual’s behavior is so severe that the researcher cannot wait to establish a baseline and must begin with an intervention. In this case, a B-A-B design is used. The intervention is implemented immediately (before establishing a baseline).
What is the value of using ABAB design?
What is the value of using an ABAB design? The effects of a single form of treatment are studied twice in the same subject.
What are the disadvantages of an ABAB design?
The A-B-A-B design, such as the graph above, allows for better experimental control and, therefore, is favored. However, there are drawbacks to this design, such as irreversibility of behavior. For example, it may be dangerous and unethical to withdraw a client’s treatment that reduces self-injurious behavior.
What is the fifth guideline when using an ABAB design?
The fifth requirement concerns those extraneous factors that might be associated with , or at least present during, the intervention condition and are not shared with the control condition.
What is an ABAB research design?
An ABAB research design, also called a withdrawal or reversal design, is used to determine if an intervention is effective in changing the behavior of a participant. The design has four phases denoted by A 1, B 1, A 2, and B 2. In each phase, repeated measurements of the participant’s behavior are obtained.
Can the A-B-A-B design be altered?
The A-B-A-B design can obviously be altered to include any number of baselines and treatment phases. To determine the effects of treatment and the degree of extinction only, a simpler A-B-A design would be used To determine if additional training changes the ultimate results, a more complex A-B-A-B-A-B-A-B could be employed.
What is the ABAB method in psychology?
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. Some interventions may increase over time while others grow weaker as the person being studied becomes accustomed to the intervention.
What is the A-B design in ABA?
Rhea A-B Design has Just two phases: baseline and treatment, where A = baseline and = treatment (Malingerer, p. 7). An A-B Design is used in ABA research and can be used to compare a baseline and treatment method to determine whether the behavior changed in the expected way after treatment.
