Autism treatment commonly employs two methods: the ABA design or the ABAB design. Both offer significant insights into the efficacy of interventions and serve as key decision-making tools in behavioral analysis.
However, few people know the differences between these approaches and how they contribute to understanding and improving behavior. This article will delve into the details of ABA and ABAB designs.
ABA Design Overview
We have the ABA design, otherwise referred to as the reversal design, which comprises three distinct phases: a baseline phase (A), an intervention phase (B), and a return to the baseline phase (A). In this approach, the first phase, known as baseline, involves observing and recording the behavior without interference or alteration.
After observation is the intervention phase, where evidence-based methods and positive reinforcement are utilized to aim for a desired change in behavior. Finally, the last stage is the return to baseline phase, during which the intervention is removed, and the therapist observes whether the behavior reverts to its original baseline level or any sustained effects from the intervention. With that said, let’s take a closer look at some key benefits of ABA therapy:
- It’s empirical, which utilizes evidence-based practices and not just assumptions.
- It’s data-driven, meaning no guesswork is involved. Events are objectively measured.
- Its Individualized Approach means the individual’s needs and abilities determine the treatment offered.
ABAB Design
ABAB design, also known as the withdrawal design, consists of four distinct phases: baseline (A), intervention (B), withdrawal (A), and reintervention (B).
During the initial baseline phase, the targeted behavior is observed and measured without any intervention, creating a starting point for comparison with the rest of the phases.
Next, the intervention phase is introduced to assess any potential improvements in behavior. The third phase involves withdrawal of the intervention, which allows for a return to the baseline level of behavior. If the behavior changes significantly during the intervention phase, this withdrawal phase helps determine if the changes were due to the intervention or other factors.
In the final phase, the intervention is reintroduced to evaluate its effectiveness. This ABAB design is widely utilized in applied behavior analysis (ABA) research to accurately assess and measure the impact of interventions on behaviors of interest.
The advantages of this design are:
- Its robustness in comparing results
- Its ability to assess several behavioral domains
- It’s capacity to determine whether a positive change seen during the initial intervention phase can be consistently replicated.
ABA vs. ABAB similarity and difference
The primary objective of both ABA and ABAB designs is to assess the efficacy of interventions in applied behavior analysis. ABAB design is a good option for obtaining a more comprehensive understanding of a client’s response to the intervention.
Through its multiple reversals, the ABAB design allows behavior to be consistently evaluated over time, leading to better comprehension and comfort for the client. ABA, on the other hand, might be preferable for behaviors that are expected to show rapid changes or when working with individuals who have a faster rate of understanding interventions.
