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.

How is experimental control demonstrated in a multielement design?

What is shown graphically in a multielement design? The data points for each of the separate conditions are connected, and any systematic deviation from the baseline or a control condition demonstrates experimental control or allows for an evaluation of the independent variable.

What is a simultaneous treatment design?

Abstract. The simultaneous-treatment design provides a means of comparing 2 or more different treatments with an individual S. The different treatments are implemented in the same phase but are balanced with respect to different conditions of administration (e.g., treatment agents, time periods, and situations).

How do you make an alternating treatment design graph?

What is multielement?

: composed of, containing, or involving more than one distinct part or aspect : having or involving more than one element The surfaces of lens elements reflect small amounts of light, the elements themselves absorb small quantities; in complex multielement lenses (especially zoom lenses) these differences can add up to …

What are the 5 experimental designs used in ABA?

  • Repeated reversals.
  • BAB reversals.
  • Multiple treatment design.
  • NCR reversal technique.
  • DRO/DRI/DRA reversal technique.

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.

Why is multiple baseline design used?

The multiple baseline design is useful for interventions that are irreversible due to learning effects, and when treatment can’t be withdrawn. In this design, behavior is measured across either multiple individuals, behaviors, or settings.

What is a multielement design ABA?

A multielement design is also known as an alternating treatments design, because it measures the effect of multiple treatments delivered one after the other. For instance, two treatments may be compared in order to see which is most efficient in producing the target behavior.

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 the basic goal of alternating treatment designs?

Used in functional behavior analysis to determine the factors that influence a behavior that can lead to the choice of an intervention. Also called the concurrent schedules design; treatment conditions are presented simultaneously rather than being alternated; somewhat difficult to plan and implement.

What is withdrawal design?

an experimental design in which the treatment or other intervention is removed during one or more periods.

What does multiple baseline design mean?

an experimental approach in which two or more behaviors are assessed to determine their initial, stable expression (i.e., baseline) and then an intervention or manipulation is applied to one of the behaviors while the others are unaffected.

What is a non concurrent multiple baseline design?

Nonconcurrent multiple baseline designs stagger the timing of baseline-to-intervention changes across various entities, but the baselines and intervention phases are not contemporaneous across each of the tiers.

Is withdrawal design the same as reversal design?

Reversal Design: reversing between treatments (e.g., baseline, treatment, NCR, treatment, NCR, treatment, etc.) Withdrawal Design: reversing between treatment and no treatment (e.g., baseline, treatment, baseline, treatment, etc.)

When would you use 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.

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.

When would you use a reversal design ABA?

Reversal designs are used to study the effect of a treatment on the behavior of a single participant. The participant is observed repeatedly prior to treatment to establish a baseline level of behavior.

What is a social concern with using a reversal design?

What is a social concern with using a reversal design? Participants do not want the intervention to be withdrawn.

What are the disadvantages of an ABAB reversal withdrawal 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.
