A structure of nursing knowledgeThe theoretical works are nursing frameworks that have been organized into types, and the theorists who have been selected for each type. The identification of selected works within each of the types is arbitrary at best. Effort has been made to reflect the level of abstraction for each type or preference of the theorist. Types of knowledge, levels, and examples of each within the structure are illustrated in Table (see below), and discussed in the following text.Knowledge Structure Levels With Selected Examples for IllustrationStructure LevelExamplesMetaparadigmHuman beings, environment, health, and nursingPhilosophyNightingale’s philosophyConceptual modelsNeuman’s systems modelGrand theoryNeuman’s optimal client stabilityTheoryFlexible line of defense moderate optimal client stabilityMiddle-range theoryMaintaining optimal client stability with structured activity (body recall) in a community setting for healthy agingModified from Alligood, M.
