Unit 5: Theories in Research and Practice

In Units 3 and 4, you examined theories from other disciplines that are used in nursing. Some of these theories are used without modification in nursing such as Lewin’s Change Theory to support practice changes. Other theories are used as a foundation for development of nursing theories such as Peplau’s Theory of Interpersonal Relations founded on the work of Harry Stack Sullivan. Clearly, many non-nursing theories are used in the development of middle range theories in nursing.

Identify a middle range theory in nursing that has links to a non-nursing theory. Describe the theory and explain the relationship to the related non-nursing theory. Connect the selected middle range theory to nursing research or advanced nursing practice.
