An Outside Perspective
Case Studies Within Psychotherapy Trials: Integrating Qualitative and Quantitative Methods presents a specific, mixed-methods approach, called the “Cases Within Trials” (CWT) model, to psychotherapy research, combining the results from a randomized clinical trial (RCT) with systematic case studies involving contrasting outcomes drawn from the experimental condition of the RCT; and a synthesis of the two types of knowledge. Chapters 3–6 of the book present four specific and diverse projects that concretely illustrate the CWT method. Chapter 7 presents an outside perspective on the four projects from a research team expert in conducting traditional RCTs. The authors explore the benefits of the CWT approach, such as confirming certain findings and challenging other findings in the quantitative group literature, and coming up with new hypotheses emerging from individual differences within group findings. In addition, the authors document some of the challenges of the CWT approach, such as confirmatory bias and case selection.
