Some 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 the 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.
