Framework of Practice
The Theoretical Foundation of
Nursing
 Nursing theory provides the theoretical
foundation of the profession.
 Theory defines what nursing is, what it
does, and the goals or outcomes of
nursing care.
 Nursing is the synthesis of many
theories.

Components of the Theoretical
Foundation
 A theory is a set of concepts and
propositions that provides an orderly way
to view phenomena.
 Concepts and propositions are the
structural elements of a theoretical
foundation.

3-3
Concepts
 Building blocks of a theory
 Labels or names for
phenomena/observable facts
 Assist us in formulating a mental image
about an object or situation

3-4
Concepts
 Theories are formed by linking concepts
together.
 A conceptual framework links global
concepts together.

3-5
Conceptual Model
 The “symbolic representation of empiric
experience in words, pictorial, or graphic
diagram, mathematical notations or
physical material.”

Propositions
 A proposition is a statement that
proposes a relationship between
concepts.
 Propositional statements in a theory
represent the theorist’s view of which
concepts fit together.

Theories
 A theory helps us to organize our
thoughts and ideas.
 In science, the purpose of a theory is to
guide research, support existing
knowledge, or generate new knowledge.
 The term theory is not restricted to the
scientific world.

Importance of Nursing Theories
 Framework for thought in which to
examine situations

Grand Theory
 Provides an overall framework for
structuring broad, abstract ideas.
 Composed of concepts representing
global and extremely complex
phenomena.

3-13
Middle-Range Theory
 Provides a perspective from which to
view complex situations and a direction
for interventions in three levels of
abstractness.
• High middle-range
• Middle middle-range
• Low middle-range

Florence Nightingale’s Influence on
Knowledge Development in Nursing
 Described nursing as both an art and a
science.
 Stressed the importance of caring for the
ill person rather than the illness.

result of environmental influences
(cleanliness, light, pure air, pure water,
efficient drainage).

Florence Nightingale’s Influence on
Knowledge Development in Nursing

The Evolution of Nursing
Theory
 Since the early 1950s, many nursing
theories have been systematically
developed to help describe, explain, and
predict the phenomena of concern to
nursing.

Knowledge Development
in Nursing
 Paradigm
• A particular viewpoint or perspective
• A “worldview” about the phenomena of
concern in a discipline (Kuhn, 1970)
 Metaparadigm
• The major concepts in a discipline that
names the phenomena of concern

3-18
Knowledge Development
in Nursing
 Metaparadigm of Nursing
• Person: Individual, family or group
• Health: Continuum of wellness to terminal
illness
• Environment: Place or community where
care is provided
• Nursing: Actions; interactions of the nurse
with the person

Knowledge Development
in Nursing
 Two individuals with different
paradigmatic views can look at the same
phenomenon and view the phenomenon
differently.

3-20
Knowledge Development
in Nursing
 The prevailing paradigm in a discipline
represents the dominant view of
particular concepts.
 A paradigm revolution is the turmoil and
conflict that occur in a discipline when a
competing paradigm gains acceptance
over the dominant paradigm.

3-21
Knowledge Development
in Nursing
 A paradigm shift refers to the acceptance
of the competing paradigm over the
prevailing paradigm or a shifting away
from one worldview toward another
worldview.
 Members of a discipline cannot subscribe
to two competing paradigms at the same
time.

The Science of Unitary
Human Beings
 Developed by Martha Rogers in 1990.

energy field that unites all aspects of the
person into a unified whole.

organization of these energy fields to
heighten the integrity of the person.
