Exploring the theoretical basis of nursing using advanced techniques of concept analysis.

In this article, the traditional methods of concept development are critiqued, and alternative methods that use qualitative methods of inquiry are presented. Variations of concept development techniques appropriate to the maturity of the concept being explored are then described, including methods for concept delineation, concept comparison, concept clarification, concept correction, and concept identification. To illustrate the application of concept development methods to nursing theory, a research program to delineate the construct of comfort is described.
