Alternating Treatments Design • Use when: – You want to determine the relative effectiveness of more than one treatment on a given behavior – Baseline data are either unavailable or might be unstable – Treatments are sufficiently different from each other – Participants can discriminate the treatment conditions
Full Answer
What is alternating treatments design in psychology?
Alternating treatments design: One strategy for comparing the effects of two treatments in a single subject. A little used and often confused design, capable of comparing two treatments within a single subject, has been termed, variously, a multielement baseline design, a multiple schedule design, and a randomization design.
What is the three-phase alternating treatments design?
Lastly the three-phase alternating treatments design is an initial baseline phase followed by the alternating treatments phase and a final best treatment phase. Applied Behavior Analysis (2nd Edition)
What is the alternating treatment design in abab?
In the alternating treatment design, following a baseline phase, the treatments are alternated in rapid succession (compared to the ABAB design which has more within phase observations or measurements) allowing a comparison of the treatment to baseline or an alternative treatment over repeated observations (e.g., ABABABABAB and ABCBCBCBC).
What are the disadvantages of alternating treatments design?
Alternating Treatments Design • Disadvantages – No controls for extraneous variables are present. You cannot make statements about absolute effects of treatment, only relative ones – Not an appropriate design for behavior that is learned in stages. – Should not be used when treatments need to be administered continuously to be effective
When implementing an alternating treatment design what is it recommended to?
To implement an alternating treatments design, begin as usual with a brief baseline, simply to ensure that the client actually needs intervention to eat those foods. You then alternate meals back and forth between the two different treatments that you want to evaluate.
What are the advantages of an alternating treatment design?
Alternating treatment design has the following advantages: Efficiently compares intervention effectiveness. It does not require withdraw. It can be used to assess generalization effects.
What are 2 limitations of the alternating treatments design?
limitation of alternating treatment designs: o it is susceptible to multiple treatment interference, o rapid back-and-forth switching of treatments does not reflect the typical manner in which interventions are applied and may be viewed as artificial and undesirable.
What is an example of an alternating treatment design?
For example, a researcher comparing two methods for eliminating the disruptive classroom behavior of a student might have the teacher use one method throughout the morning and the other method throughout the afternoon and then evaluate the student's behavior with each technique.
Why is ABAB design typically superior to AB 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 a limitation of the alternating treatments design quizlet?
What assessment uses an alternating-treatments design to identify the maintaining function of a behavior? What is a limitation of the alternating-treatments design? a.It is not effective for assessing the effects of the independent variable that produces change over long periods of time.
What is the reason for counterbalancing in alternating treatment designs?
Counterbalancing functions to decrease all factors extraneous to the treatment and their influence on the dependent variable.
Which of the following is considered to be a reason for using a BAB design instead of an ABA design?
Which of the following is considered to be a reason for using a B-A-B design instead of an A-B-A-B design? This design is considered the most "straightforward" and generally most powerful within-subject design for demonstrating a functional relationship.
What is an ABAB study?
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.
Which experimental design should I use?
Ideally, your experimental design should: A common method is completely randomized design, where participants are assigned to groups at random. A second method is randomized block design, where participants are divided into homogeneous blocks (for example, age groups) before being randomly assigned to groups.
What is a problem with the reversal design?
There are two potential problems with the reversal design—both of which have to do with the removal of the treatment. One is that if a treatment is working, it may be unethical to remove it.
What is the basic goal of a changing criterion design?
What is the basic goal of a changing criterion design? evaluate the effects of a treatment on the gradual increase or decrease of a single target behavior.
