In recent years, clarification of the relationship between conceptual models of nursing and theories of nursing has made it possible to use nursing processes as research techniques that combine both inductive and hypothetico-deductive commitments. Therefore it opens the perspectives that systemic use of the nursing process may identify a set of research methods that may facilitate development of nursing theory involving use of insights from both the direct experience of practicing nurses and conceptual models of nursing. Like any knowledge, nursing knowledge is also a blend of knowledge from nursing and other disciplines. Nursing knowledge needs to be unique to be regarded as professional body of knowledge. The nursing research needs to develop and confirm nursing knowledge, and to be able to do this, nursing research needs to be linked to nursing theories. Thus nursing theory can form a conceptual framework for research studies, can be tested by research, and can be built by development of theory from research into practice. In this way, nursing research is closely related to nursing theory and hence to nursing practices (LoBiondo-Wood & Harber, 2006).
Types of nursing theories generally include grand theory, middle-range theory, and practice theory. ...
