Theories and conceptual models are invented or created, not discovered. A theory, but not a conceptual model, consists of concepts and a set of propositions that form a logically interrelated system, providing a mechanism for deducing hypotheses from the original propositions. Several conceptual models of nursing have been used in nursing research, so they do not need to be borrowed from other disciplines.
