Is Maslow's hierarchy of needs considered a middle-range nursing theory developed by a nurse?

Maslow's hierarchy of needs is not considered a middle-range nursing theory developed by a nurse. Instead, it is a psychological theory created by Abraham Maslow in the 1940s. The hierarchy outlines a model of human motivation organized in a five-tier pyramid structure, ranging from basic physiological needs to self-actualization. While nurses may use Maslow's theory to understand patient needs and prioritize care, the theory itself originates from psychology rather than nursing.

Middle-range nursing theories are typically developed by nurses and specifically address nursing practice, with a focus on a specific aspect of patient care. Since Maslow's model is broader and not exclusive to nursing, it does not fit the criteria for a middle-range nursing theory. It can influence nursing practice and is often adapted to fit nursing needs, but this adaptation does not change its origin or classification as a psychological rather than nursing specific theory.
