What is the difference between a model and a theory in nursing

A theory is a group of related concepts that propose action that guide practice whereas a Theory refers to “a coherent group of general propositions used as principles of explanation”.

A nursing theory is a set of concepts, definitions, relationships, and assumptions or propositions derived from nursing models or from other disciplines and project a purposive, systematic view of phenomena by designing specific inter-relationships among concepts for the purposes of describing, explaining, predicting, and /or prescribing. Nursing theories, like any theory of any discipline, are meant to explain behavior, phenonema, etc. There are theories of nursing that explain the grieving process of mothers who experienced perinatal loss, theories that explain how patients view illness, etc.

In summary, nursing models can be evaluated by carefully considering how human beings are conceptualised within a model, how adequately the model guides nurses in the decision-making associated with all stages of the nursing process and how appropriate is the expected role of the nurse.  distinction has been drawn between nursing models and nursing theory with a rationale for considering nursing models as precursors of nursing theory especially as there are similarities in the criteria used to evaluate them both. The nursing process has been described as a systematic, problem-solving approach to care. It is neither a nursing model nor a theory but rather one way of organising nursing activities. 

Simply put, both a model and a theory state possibilities and provide explanations for natural phenomena. Models can be used in the formulation of experimental setups as the scientist performs the steps of the scientific method. They give structure for the formulation of theories.

Models may also serve as the representation of possibilities with respect to the premises of theories; scientists can create simulations and formulate hypotheses modeled after the theories. In some cases, models can also be used to confirm a theory. They serve as the variable for experiments needed for the testing of the theory’s correctness.

The nursing model, as opposed to the medical model is simply a thing to describe how nurses practice – a framework of thinking. You might hear how CRNAs (nurse anesthetists, for example) practice under a more medical than nursing model. Nursing tends to be more wholistic, and views patients as sums of their parts rather than just parts; a medical model tends to view patients in specific body systems as opposed to an entire being.

Words are loaded in theory, and the main reason for the proliferation of meanings is the proliferations of theories. Theory determines the meaning of a concept. Therefore, a word that means something in the context of theory A could mean something different in the context of theory B, and the difference could be more or less subtle.

Theories are considered structured words (i.e., it is the structure of words that gives sense to a theory). Therefore, the location of each word gives sense to those specific theories. If word structure is changed or different words are adopted for a specific concept, the meaning of the theory will change.

The single best way to clarify a concept is to explain the theory to which this concept is applied. However, adopting a specific theory does not end conflict. If the same term appears in different theories, it might generate a conflict. To solve such methodological problem, it is necessary to verify the appearance of the concept in different theories. A concept is not classified without a theoretical commitment through review of different theories in an attempt to define the concept that appears in different contexts.

CLASSIFICATION OF NURSING THEORIES

Depending on the generalisability of their principles

• Grand theory: provides a conceptual framework under which the key concepts and principles of the discipline can be identified.
• Middle range theory: is more precise and only analyses a particular situation with a limited number of variables.
• Metatheory: the theory of theory. Identifies specific phenomena through abstract concepts.
• Practice theory: explores one particular situation found in nursing. It identifies explicit goals and details how these goals will be achieved.

COMMON CONCEPTS IN NURSING THEORIES

• Four concepts common in nursing theory that influence and determine nursing practice are
  • The person( patient)
  • The environment
  • Health
  • Nursing (goals, roles, functions)
• Each of these concepts is usually defined and described by a nursing theorist. Of the four concepts, the most important is that of the person. The focus of nursing is the person.
