One of the key aims of any health and social care research is that it is used to inform practice. To make sure that research is useful we often compare it to what we know, what we have experienced and what seems likely. That is we test it to see that it fits our mental map of practice. Within research there are several ways that we can improve the quality and applicability of research. One of the key ways, within the research process, is to triangulate the ways in which the study information is collected. This can be done by triangulating either the methodologies or methods within a study.
