Applied Single-Subject Project
Instructions:
Design and present a single-subject research study based on a case study. Students will define the dependent variable (based on the target problem behaviors) in measurable and observable terms, utilize an appropriate measurement system, and evaluate the effects of a treatment through graphing the data in an appropriate single-subject research design. Students will then assess the generalization of the treatment effects and evaluate the effectiveness of a strategy for promoting treatment generalization.
Please read the following case study and use it to answer the questions below.
John is a 12-year-old boy who has been diagnosed with Attention Deficit Hyperactivity Disorder (ADHD). Sometimes when in class at school, John engages in disruptive behavior, particularly when the teacher is asking questions that John does not know how to answer. This can happen several times during the day (typically 4-5 times on average), and occurs in three of his classes (math, language arts, and science).
John's disruptive behaviors specifically include yelling profanities, kicking over his desk or the desk of another student, and tipping over his chair such that it falls to the floor with him in it. All of his classes are general education classes, and other students complain when John has one of his outbursts. At times he has injured himself or another student as well.
After John engages in a disruptive behavior (as described above), his teachers typically tell him to go sit in the "calm corner" where there are books to read. He is allowed to stay there for 5-10 minutes before he is required to resume working on his tasks.
A behavior analyst conducts a functional behavior assessment and determines that the function of the disruptive behavior is escape from task demands. She collects baseline data on the dependent variable and then implements an intervention that involves John being given access to the calm corner based on requesting a break from his schoolwork (and NOT based on engaging in disruptive behavior). At first, John is allowed to ask for a break up to 5 times a day in the class where the intervention is introduced (Classroom 1). (Later this will be faded down to one time per day.)
After collecting data for several sessions while the intervention is in place, the intervention is removed such that John does not get access to the calm corner based on requesting a break, but instead gains access as a result of his disruptive behavior (as in baseline). In the fourth phase of the study, the intervention is reinstated and the effect on disruptive behavior is again measured.
Part I: Treatment Effectiveness
Identify the dependent variable being addressed in the case study. To do this, you should specify at least three specific target behaviors that are considered part of the overall response class (i.e., the set of responses that achieve the same function).
Define each of the target behaviors in specific, observable, and measurable terms.
Identify what measurement dimension of the overall dependent variable will be assessed (i.e., frequency, duration, latency, etc.) with what type of recording system (e.g., permanent product recording, event recording, interval recording, etc.). (Please refer to Table 7.2 on page 152 in your textbook by Mayer et al. (2022) for a chart of possible methods and reasons to use them.)
Identify what single-subject design is being used to evaluate the effects of the intervention.
Create a graph of the data during the four phases (see table below). (You can refer to Exercise 2 from Course ABA504 to learn how to graph this type of single-subject design using Excel.) Get dependable, budget-friendly assignment help-starting today!
Examine your graph and state whether the intervention was effective.
Explain your conclusion based on principles of visual analysis. Refer to the magnitude/level of performance, the trend in performance, and the variability in performance for the data in each phase.
