Theory can be defined as “one or more relatively concrete and specific concepts that are derived from a conceptual model, the propositions that narrowly describe those concepts, and the propositions that state relatively concrete and specific relations between two or more concepts” (Butts & Rich, 2018, p. 101). Theory is a hypothesis tested and measured to explain, predict, describe, and prescribe relationships between concepts and is developed through quantitative research. The difference between a model and a theory is the amount of proof that exists in demonstrating the outcomes they predict. Both models and theories show relationships between concepts. Directions In this assignment, you will locate a grand and middle-range nursing theory and examine the utility of your chosen theories for guiding research and practice.

You will locate one grand nursing theory and one middle-range nursing theory applied in a research study. You will examine how each theory was applied within the research study and then analyze the utility of grand and middle-range nursing theories to advance the discipline of nursing and its impact upon your advanced nursing practice.
