Case Studies Within Psychotherapy Trials
The Cases Within Trials (CWT) model combines the randomized clinical trial (RCT) research design, based on quantitative group research, with richly and qualitatively detailed systematic case studies involving contrasting outcomes drawn from the experimental condition of the RCT. Chapter 1 of the book provides the broad historical and methodological context out of which the CWT method developed, including the recent dramatic growth of mixed-methods approaches in psychotherapy research generally, with an associated increase in their credibility and rigor. Chapter 2 presents the details of the CWT method and its application to Chapters 3–6, which present four specific projects that concretely illustrate the CWT method. The four projects vary across such dimensions as theoretical orientation and type of mental disorder. To facilitate comparison across projects, each is organized in three main sections, including results gained from the RCT, results gained from the case studies, and a synthesis of the two types of knowledge. Each project concludes with a commentary by an outside expert (or expert team) in the theoretical and disorder focus of the project. Chapter 7 presents an outside perspective on the four projects from a research team highly experienced in conducting and thinking about traditional RCTs. In view of the four projects as a whole, Chapter 8 presents the editors’ summary and analysis of themes and guidelines for the future embodied in the knowledge gained from the four projects.
