Evaluating Single-Subject Treatment Research: Lessons.
The fact of the matter is that the majority of aphasia treatment research was completed before the five-phase model was broadly recognized. Not surprisingly then, some appraisals of the body of literature have been rather harsh when assessment criteria were grounded in the five-phase system.This narrative review provides an overview on the topic of bias as part of Plastic and Reconstructive Surgery's series of articles on evidence-based medicine. Bias can occur in the planning, data collection, analysis, and publication phases of research. Understanding research bias allows readers to.Robey and Schultz have made a significant contribution to the field by outlining a five-phase model for conducting treatment outcome research. Briefly, the purpose of phase 1 studies is to establish the treatment's safety, and to detect whether the treatment is active.
They are, of course, only an option in areas of clinical outcomes research that has already established strong treatment efficacy. It is also important to appreciate what a well conducted study of intervention efficacy does not tell us.Welcome to the Clinical Outcomes Research Office. Our office is a full-service research enterprise that provides support in the design, execution, and analysis of clinical research studies that seek answers to clinical questions.
When standard, phased models for clinical-outcome research (Robey, 2004) are applied to our current evidence base, it is clear that we are only at phase 1 of the five phases. This is the phase at which therapies are defined and single.
