What is reversal design?

A straightforward single-subject design that demonstrates a functional relationship by having the IV systematically absent and present.

What are behaviors that cannot be reversed?

Study Notes

Reversal Design Overview

Reversal design is also known as withdrawal design.
ABAB design is a straightforward single-subject design demonstrating a functional relationship through systematic intervention presence and absence.

Behaviors in Reversal Design

Irreversible behaviors include those that gain new reinforcement contingencies or are complex educational concepts.
Reversible behaviors can improve or worsen, e.g., raising a hand in class versus hair pulling.

Assumptions and Limitations

Three key assumptions:
- Target behaviors are reversible.
- Changes result from experimenter-controlled contingencies reverting to baseline when removed.
- Lack of reversibility questions the existence of a functional relationship.
Limitations include:
- Some behaviors are irreversible.
- Ethical concerns arise with reversing certain behaviors (e.g., self-injurious behavior).
- Client buy-in can be challenging.
- Pragmatic issues may hinder feasibility.

Baseline Logic Elements

Three elements: prediction, verification, replication.
Prediction involves projecting behavior levels based on baseline if no intervention is introduced.
Verification confirms behavior reverts to baseline levels without the intervention, ensuring the IV's effect is valid.
Replication involves repeating conditions previously tested for reliability.

ABAB Graph Standards

Baseline logic must rule out threats to internal validity and meet quality indicators.

Quality Indicators

Requires a minimum of three data points per phase and three effects measured at three distinct times.

Variations of Reversal Design

Types include repeated reversal, intervention reversal (BAB), and multiple treatment reversal.
Repeated reversals involve further withdrawing and reinstating the IV multiple times, highlighting its impact.
Intervention reversal introduces treatment before baseline assessment, usually for urgent cases or dangerous behaviors.

Multiple Treatment Reversal Designs

Compare effects of two or more IVs and require reintroducing baseline measures after each variable.
Terms ABA, ACA illustrate verification and experimental control in this design.

Challenges with Other Designs

ABCDE designs present low experimental control due to order and sequence effects and lack baseline verification.
Sequence effects can compromise results based on previous treatments affecting individual behavior.
Order effects disrupt results when the sequence of treatment experiences influences study outcomes.

Issues in Multiple Treatment Reversal

Problems arise from the complexity of reading results, difficulty in identifying relationships, and potential order and sequence effects compromising the integrity of findings.
