Case Study 1: Martin
Martin, a behavior analyst, is working with Sara, a 14-year-old girl with severe developmental delays who exhibits self-injurious behavior (SIB). The self-injurious behaviors included pulling her hair, biting her arm and banging her head against the wall. After conducting a functional analysis, Martin decided to employ an intervention program consisting of differential reinforcement of other (DRO) desired behavior. Martin collected data on Sara's SIB before and during the intervention. Below is a depiction of the data that Martin collected:

A number of considerations must be taken into account when deciding to use ABAB. Some ethical implications when selecting a reversal design such as ABAB when working with the type of behavior problems that Sara exhibiting is “it may not be ethical to remove the treatment in the second baseline if the behavior is dangerous (e.g., self-injurious behavior)” (p.50). “Second, you must be fairly certain that the level of the behavior will reverse when treatment is withdrawn. If the behavior fails to change when the treatment is withdrawn, a functional relationship is not demonstrated” (p.50). A number of considerations must be taken into account in deciding whether to use the A-B-A-B research design. First, it may not be ethical to remove the treatment in the second baseline if the behavior is dangerous (e.g., self-injurious behavior). Second, you must be fairly certain that the level of the behavior will reverse when treatment is withdrawn. If the behavior fails to change when the treatment is withdrawn, a functional relationship is not demonstrated. Another consideration is whether you can actually remove the treatment after it is implemented. For example, if the treatment is a teaching procedure and the subject learns a new behavior, you cannot take away the learning that took place. (For a more detailed discussion of considerations in the use of the A-B-A-B design,
