A conceptual model provides an understanding about how a health care challenge will best be explored and addressed, and it offers a logical structure of connected elements that help provide a picture or visual display of how ideas in a study or project relate to one another. Existing conceptual models can be found in the literature, or they can be created by the researcher or the team exploring and addressing the problem. A theoretical framework is derived from an existing theory in the literature that has already been tested and validated by others and is considered a generally accepted theory in scholarly literature. A good way to distinguish between a conceptual model and a theoretical framework is to think of the conceptual model as the floor plan of a house and the theoretical framework as the 3-D image showing the spatial relationships among rooms.
