Models of nursing (conceptual framework) relation between models andtheory model building in nursing

Theory defined as a supposition or system of ideas that is proposed to explain a given
phenomenon. Or A theory is a sets of concepts & propositions that provides an orderly way
to view phenomena.
Nursing theory differentiates nursing from nursing from other disciplines and activities
that in that the purposes of describing, explaining, predicting and controlling desired
outcome of nursing care practices.
The purpose of theory: In scientific disciplines is to guide research to enhance the science
by supporting existing knowledge or generating new knowledge. A theory not only helps us
to organize our thoughts and ideas, but it may also help direct us in what to do and when
and how to do it. It supports the development of knowledge through thesis and
contestability. Theory not only explains and predicts outcome but also supports in decision
making.
The use of the term theory is not restricted to the scientific word, however. It is often used
in daily life and conversation.
All nursing theories have common concepts. Which are influence and determine nursing
practices are:
1. The person or client (individual, family, group or community)
2. Environment (Internal & external)
3. Health (the degree of wellness or wellbeing that the client experiences.)
4. Nursing, the attributes, characteristics and actions of the nurse providing care on
behalf of, or in conjunction with, the client.
A conceptual framework helps construct a "house" of relevant information. This house
explains, either graphically or in narrative form, the main things to be studied or taught
and the relationships among them. A conceptual framework for a thesis acts as a visual
outline to represent the concept or research idea ‐ the way the researcher shapes it
together. This framework expands upon the research problem as it associates to pertinent
literature research. Part of conceptual framework offers a synopsis of the study’s main
points. The framework shows the central factors influencing the relationship of the
primary variables/elements or constructs ‐‐ and how all relate to the stated hypothesis.
Or A conceptual Framework is group of related ideas, statements or concepts. For example
Freud’s structure of mind (Id, ego and superego) could be considered a conceptual
framework or model.

Models make precise assumptions about a limited set of parameters and variables.
Generally analysts use models to fix variables at specific settings and to explore the
outcomes produced.
Models allow analysts to test specific parts of theories.
For example
Situating models within theories and theories within frameworks keeps analysts honest,
supports the scientific enterprise and encourages the cumulation of knowledge. This ideal
is rarely met.
All good nursing theories are based on specific models for example Nightingale’s theory
based on Environmental Model, Peplau’s theory based on Interpersonal relationship model,
Orem’s theory based on Self‐care deficit theory, King’s theory based on Goal Attainment
Model, Roy’s Adaptation theory based on Adaptation model.
How is the term “theory” related to “model” and what else should these terms be related
to?
There are three of concerns about the usage of these terms. First, the terms “models”
And “theories… have been widely used as interchangeable in the profession”. Second
related Point is that, the term “theorist” usually means “model builder.” Third, a theory
involves more than technical/analytical desiderata:“Scientific culture understands theory
to entail requirements of importance and usefulness”
Nursing Theory and Model Relation Page 3
As a conclusion it said that “theory” has a higher normative status than “model.” Moreover,
few of Scientist believes that a theory does not require a “model” and a “model” is not
sufficient for a “theory.”
Notice that this set of requirements for a modelbased
theory has three characteristics:
First, “models” are theory wannabes. Only a really good model gets promoted to theory
status.
Second, the idea that “theory” might operate at a very general level, while “models” might
be specific applications of a theory (a theoretical framework) is missing.
Third, this usage makes no allowance for the possibility that models are sometimes (though
not always) a link between theory frameworks and the activities of empiricists.
