Fidelity means in a research study that you do the study exactly as you plan to do the study. It’s really crucial when you’re planning a study to set up what your sampling criteria are, what population you want your results to apply to, what your inclusion, exclusion criteria are. Where are you going to get the subjects for your study? What measurements are you going to get, when you’re going to get them, how you’re going to get them, by whom you’re going to get them. All of this is part of design and, once the study starts, nothing should change. It should be done exactly as you plan to do it. Fidelity is that the researchers do the study as they plan to do it.
