The research design operationalizes the elements of an RCT and places it within the social context for the study. Building on a strong conceptualization and what is known about the service setting, the design provides a detailed, replicable strategy for answering the research question. Chapter 5 reviews the elements and critical decision points in RCT study design. These include the basic logic of RCT designs, identifying and controlling for common confounds in RCT results, and various randomization procedures. Other important aspects of design relate to sampling, outcome measurement, and timing of outcome measurement points. At the center of any RCT, the clear conceptualization of conditions enhances the capacity of the study to inform practice. Data analysis and emerging alternatives to traditional RCT design are also addressed.
