The designs we have reviewed so far have consisted of studying a single behavior across conditions over time. Hayes et al., (1999) refer to these as within-series designs (e.g., B-only, AB, AB*, changing criterion, periodic treatment). But there are other situations in which we may want to compare two different interventions, or the effectiveness of...
This chapter helps you use Therapy-Science’s iGraph™ to graph, visualize, and analyze your client’s performance for evidence of improvement over the course of therapy. The first three sections in Chapter 6 focus on the fundamentals of single-case graphs including its graphical components and measurement basics (level, trend, variability/stability). The next four sections introduce single-case design...
You are now at the point in this text to be able inspect the data that you have collected for evidence of positive clinical change. How do you know that your client is improving? What does it look like? This chapter addresses the visual- quantitative analysis of data collected within a single-case framework. Continue reading...
The following set of procedures for doing of single-case performance data is based, in part, on the recent work of David Gast and colleagues (Gast & Ledford, 2014; Lane & Gast, 2014). In visual analysis it is important to first describe and analyze level data, in terms of , Continue reading...
Traditionally, practitioners of single-case data design have used visual means to describe and analyze the level, trend and stability of their client’s behavior within and between adjacent phases (Parsonson & Baer, 1986). In recent years, visual analysis has been augmented by increasingly powerful statistical techniques and computer-based visualization methods (like Therapy-Science!). Continue reading...
Throughout this book, I’ve provided you with a set of tools for using the information that you obtain from your practice to guide you as you go about making decisions about your client: their current status and where to go next. However, it’s one thing to be given a set of tools and another to...
