This document discusses theoretical and conceptual frameworks. It defines a theoretical framework as providing rationale for relationships between variables in a research study, analogous to the frame of a house. A conceptual framework outlines courses of action or preferred approaches. The document describes developing frameworks by selecting concepts and relationships, and defining concepts operationally. Frameworks guide entire research studies by informing hypotheses, observations, designs, and interpretations. Theories can be descriptive, explanatory, or predictive and are tested through different research types. Nursing frameworks contribute unique perspectives on persons, environments, health, and nursing. Frameworks should be clearly identified and defined, with logical relationships supported by literature.
