Chapter 6: Visually Interpreting Your Client’s Progress
In Chapter 5 we presented the guidelines for constructing good single-case design graphs. We illustrated the guidelines showing social worker Keisha’s work with Stephen, a fourth grader who is having trouble completing his homework. We’ll continue to talk about Stephen in this chapter, showing how we might interpret different patterns of data that might emerge as Keisha monitors Stephen’s progress.
This chapter discusses the visual analysis of client graphs, allowing you to assess your client’s progress in real time. You will learn how to determine whether change is occurring, and if so whether the change is positive, as well as whether the change is sufficient and occurring at an acceptable pace. We also present a number of alternatives you may consider if change is not occurring or is in the wrong direction, insufficient, or occurring too slowly. Finally, we discuss the limitations of visual analysis and how to avoid errors in interpretation.
