How do you alternate treatments in a sequence study?
You can alternate treatments back and forth (e.g., ABABABA) or you can semirandomize the sequence, with the rule that the same treatment is not conducted more than twice, consecutively (e.g., ABBABAAB). The former has the disadvantage of possible sequence effects and the latter has the disadvantage of requiring more planning effort.
Can alternating treatment phases be counterbalanced or randomized?
The alternating treatment phases can be counterbalanced or randomized. In each of these designs the researcher must attend to various features of the data, including mean changes among phases, trend, variability, and autocorrelation in the data.
Why is replication important in experimental design?
Why it matters: Replication strengthens the ability to demonstrate experimental control with an intervention’s effectiveness in behavior change. D-5: Use single-subject experimental designs (e.g., Reversal, Multiple Baseline, Multielement, Changing Criterion).
How do you design an alternating treatments design?
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 5 experimental designs used in ABA?
Six primary design types are discussed: the pre-experimental (or AB) design, the withdrawal (or ABA/ABAB) design, the multiple-baseline/multiple-probe design, the changing-criterion design, the multiple-treatment design, and the alternating treatments and adapted alternating treatments designs (see Table 2).
How is experimental control determined in an alternating treatments design?
An alternating treatment design is the rapid alternation of two or more different treatments while measuring the behavior of interest. Experimental control in this type of treatment design is determined by visually analyzing the difference between the data trends of the two (or more) treatment conditions.
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.
What kind of design is 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. This comparison demonstrates the impact of the IV on the DV (Ledford & Gast, 2018 p. 217).
What are the 7 dimensions of ABA?
It is important that an individual's treatment plan has goals following these 7 dimensions: 1) Generality, 2) Effective, 3) Technological, 4) Applied, 5) Conceptually Systematic, 6) Analytic, 7) Behavioral.
What type of assessment can the alternating treatment design be used for?
It can be used to assess generalization effects. It does not include a return to baseline. It often doesn't include a baseline to begin with.
Which best describes an alternating treatment design?
Which best describes an alternating treatment design? Multiple interventions are introduced repeatedly in an alternating pattern. These data are compared in order to determine which intervention is most effective.
What are the three phases of an ABA reversal design?
This approach allows the researcher to see whether changes in the independent variable are causing changes in the dependent variable. In a reversal design, the participant is tested in a baseline condition, then tested in a treatment condition, and then returned to baseline.
What is an experimental design?
Definition: An experimental design where the initial baseline phases are followed by a series of treatment phases consisting of successive and gradual changing criteria for rein forcement or punishment .
Why do multiple baseline designs matter?
Why it matters: Multiple baseline designs are the most widely used design due to their flexibility. They do not require the withdrawal of a treatment variable. Multiple baseline designs involve prediction, verification and replication. There are variations of the multiple baseline design.
Do experimental controls require reversal?
They do not require reversal or withdrawal of treatment. Changing criterion designs do not allow for comparison. They also involve prediction, verification and replication. Experimental control is demonstrated by the extent to which the level of responding changes in response to each new criterion.
What is an experimental design?
Definition: An experimental design where the initial baseline phases are followed by a series of treatment phases consisting of successive and gradual changing criteria for rein forcement or punishment .
Why is reverse design important?
Why it matters: Reversal designs are the most powerful single-subject design for demonstrating a functional relation between an independent and dependent variable. Reversal designs involve prediction, verification and replication.
Why do multiple baseline designs matter?
Why it matters: Multiple baseline designs are the most widely used design due to their flexibility. They do not require the withdrawal of a treatment variable. Multiple baseline designs involve prediction, verification and replication. There are variations of the multiple baseline design.
What is an independent variable?
Independent Variable. Definition: The intervention designed to have an effect on the dependent variable. Example in everyday context: Pushing the “brew” button on your coffee machine to make coffee. Example in clinical context: Response blocking as a means to prevent elopement.
Why is the client not mastering their targets?
The behavior analyst concludes that the mand program and instructional techniques are the reason why the client is mastering their mand targets and they are not mastering their targets due to any other variables.
