1. Define middle-range theories. Why are they considered to be useful in conducting nursing research? Give at least three examples of middle-range theories, discuss what these theories are all about and how these theories are useful in nursing practice and research.
Middle-range theories are a set of related concepts and proposed relationships among the concepts that can be depicted in a model. Middle-range theories are more precise and only analyses a particular situation with a limited number of variables. They contain fewer concepts and adaptable to a wide range of practice and experience. Middle-range theories are basic, usable set of ideas less abstract than grand theory and more abstract than micro-range theory. Middle-range theories are progressed and advanced at the circle of practice and research to guide casual practice and intellectual research in nursing.
Middle-range theories are sufficiently abstract to allow generalization, and yet satisfactorily grounded in reality so that they could be empirically verified. Middle-range theories present concepts and propositions at a lower level of abstraction and hold great promise for increasing theory-based research and nursing practice strategies. They may be developed inductively through qualitative research and practice observations or deductively through logical analysis and synthesis. Research based on middle-range theories can provide empirical evidence to guide practice as well as expanding knowledge bases in the nursing discipline as it seeks to define the abstract concepts and propositions in the theories. Middle-range theories stress the significance of considering the outcome of various manifestations/conditions happening together on patient’s performance and stimulate assessment of patient’s working outcomes.
