Unit 6 Case Study Name Date School Unit 6 Case Study This paper covers a case study that includes a 14-year-old girl named Sara, who has some serious developmental delays that cause her to have a self-injurious behavior. Martin, an ABA psychologist, tried to help her by using a program based on differential reinforcement of other (DRO) desired behavior that proved to be efficient in decreasing the frequency of Sara’s negative behaviors. Her negative behaviors included actions such as biting her arm, pulling her hair, and banging her head against the wall. The program Martin developed and its results are being analyzed in this paper to see how efficient it was. Martin is an ABA psychologist that decided to treat the case of Sara with a differential reinforcement of other (DRO) desired behavior, to help her get rid of her self-injurious behavior or at least decrease its frequency. For this, he needed a research design to determine if it was the treatment that was responsible for some eventual changes that were observed at the end of the treatment, or not. As DRO was being used to treat Sara’s behavior, and because this is a process that involves several steps, it became clear that the research design that Martin needed to use is the A-B-A Reversal Design. In this research design, the deadline and treatment are twice implemented, being intercalated. As already mentioned, after deciding the type of the research design to use, Martin chose the differential reinforcement of other behavior (DRO) as the best solution to the problems Sara having. The motivation for this was a really simple, as the DRO is generally used when the purpose is to decrease a certain behavior until its extinction. Because the self-injurious behavior that Sara was engaging in had to be extinguished, the DRO was definitely one of the best options Martin could have chosen. According to the
