An in situ observation technique was used to describe nursing interventions that enabled people to take greater responsibility for their own health as part of a doctoral research project with an ethnomethodological design. This article outlines the use of this research strategy that elicited the description of at least 60 enabling interventions through the observation of 30 home visits by nurses from the New Brunswick Extra-Mural Program. A review of the methodological aspects of this research is presented. Some of the salient results are also presented and discussed in light of the contributions of this observational technique to describe the multidimensional nature of enabling interventions and as a means to discover some of their indicators and functions. It is argued that an observational technique is a pertinent and a non-intrusive research strategy that can contribute to a growing body of knowledge of nurses’ enabling interventions.
