EBBPVery few trials actually fall wholly into one of these categories, but rather fall along a continuum of pragmatic- explanatory. Where the study falls on the continuum will depend on many factors, including the stage of intervention development, research question, and resources available. The stage of intervention development plays an important role. In the beginning stages, an investigator usually wants to know whether the treatment can work and, therefore, is worth developing further. The investigator may opt to keep sample size manageable by conducting a very tightly controlled efficacy study. However, later in development, once the treatment's efficacy has been established, an investigator may want to know whether the intervention can be more broadly applied in other settings and delivered by nonprofessionals who have less experience with the treatment. ![]() Designing a research project: randomised controlled trials and their principles.
