Patterns of Knowing
and Nursing Science
Copyright © 2010 Wolters Kluwer Health | Lippincott Williams & Wilkins
The Evolution of Scientific Thought
• Early humans differentiated world into two parts: me
(internal), not me (external)
– Used trial, error to discover that patterns of action
led to predictable outcomes
• Nursing functioned primarily from protocols, procedures
• Disease, aches, pains assumed to be caused by gods,
evil spirits
– Early medicine associated with religion or magical
beliefs
Copyright © 2010 Wolters Kluwer Health | Lippincott Williams & Wilkins
The Search for Certainty
• The 1500s
• Mechanistic world view
– Math
– Determinism
– Counting
– Quantity
– Philosophy of logical
positivism
– Continuity
• Time, space were
absolute
• Humans seen as having
separate psyche, soma
(Cartesian dualism)
– Impersonality
• Principles led Galileo,
Newton to develop
scientific method, based
on logic
Copyright © 2010 Wolters Kluwer Health | Lippincott Williams & Wilkins
The Relative World of Process
• Scientists realized that physical world consisted of
matter, forces that interact with matter:
– Gravity, magnetism, electricity
• All systems considered interrelated and interdependent,
on continuum of relativity and probability, thus
uncertainty
• Awareness of limitations, biases of individual perception
has increased, implying that truth and meaning are not
absolute but relative
Copyright © 2010 Wolters Kluwer Health | Lippincott Williams & Wilkins
Philosophy of Knowledge
• Plato
– Knowledge considered to be belief justified through
reason
• Philosophy considers questions such as whether there is
such a thing as truth, how one can be certain that
something is true
Copyright © 2010 Wolters Kluwer Health | Lippincott Williams & Wilkins
Question
• The prior use of scientific thought prompted nursing to
function using which method to guide care?
A. Good and evil causes for aches and pains
B. Trial and error to discover cause for illness
C. Protocols and procedures to care for clients
D. Logic- and reasoning-guided practice
Copyright © 2010 Wolters Kluwer Health | Lippincott Williams & Wilkins
Answer
• C. Protocols and procedures to care for clients
• Rationale: Nursing operated on a series of protocols and
procedures that guided client care. Trial and error, evil
spirits, and logic were all past methods of scientific
inquiry or thought. These methods did not guide nursing
practice.
Copyright © 2010 Wolters Kluwer Health | Lippincott Williams & Wilkins
Processes of Knowing
• Rationalism
• Empiricism
• Intuition
Copyright © 2010 Wolters Kluwer Health | Lippincott Williams & Wilkins
Approaches to Knowing
• Logical empiricism
– Body of facts, principles
– Cause-and-effect (linear) relationships
– It is necessary to control values, biases to achieve
“objective” knowledge
– Theoretical reduction is important scientific goal
– Whole is sum of parts
Copyright © 2010 Wolters Kluwer Health | Lippincott Williams & Wilkins
Approaches to Knowing (cont’d)
• Logical empiricism synonymous with logical positivism
– To predict, explain, control world events, situations,
occurrences
– Nursing knowledge based on “hard sciences” has
roots in logical empiricism
Copyright © 2010 Wolters Kluwer Health | Lippincott Williams & Wilkins
Approaches to Knowing (cont’d)
• Historicism based on these assumptions:
– “Truth” is dynamic, constantly changing
– Whole is more than sum of parts
– Individual or phenomenon must be studied as whole
in natural setting
– Multiple research traditions desirable to explain
different dimensions of same phenomenon
Copyright © 2010 Wolters Kluwer Health | Lippincott Williams & Wilkins
Approaches to Knowing (cont’d)
• Historicism based on these assumptions:
– Knowledge is related to context
– In professional nursing, historicism provides valueladen approach to nursing knowledge
Copyright © 2010 Wolters Kluwer Health | Lippincott Williams & Wilkins
Approaches to Knowing (cont’d)
• Postmodernism perspectives on knowledge development
are based on
– Focuses on understanding multiple meanings, ways
of knowing reality, rather than single, transcendent
meaning of reality
– Multiple truths are accepted, knowledge is considered
uncertain, provisional
– Statements reflect concern for context rather than
universality
Copyright © 2010 Wolters Kluwer Health | Lippincott Williams & Wilkins
Approaches to Knowing (cont’d)
• Postmodernism
– Emphasis of knowledge development shifts “from
concern over the truth of one’s findings to concern
over the practical significance of the findings”
– Problems are not “solved,” but “deconstructed”
– Shift toward lived experience, toward “creativity,
flexibility, uniqueness, local value”
Copyright © 2010 Wolters Kluwer Health | Lippincott Williams & Wilkins
Patterns of Nursing Knowledge
• Ways of perceiving, understanding self, world
• Gender differences have been identified in ways men and
women may develop frameworks for organization of
knowledge
– Linked to distribution of power, privilege in society
• Four fundamental patterns (ways) of knowing in nursing:
empiricism, aesthetics, personal knowledge, ethics
(Carper)
Copyright © 2010 Wolters Kluwer Health | Lippincott Williams & Wilkins
Empirical Knowledge
• “Encompasses publically verifiable, factual descriptions,
explanations, and predictions based on subjective or
objective group data”
• Obtained through senses, can be verified, is credible, is
used to impart understanding
– Explaining
– Structuring
Copyright © 2010 Wolters Kluwer Health | Lippincott Williams & Wilkins
Aesthetic Knowledge
• Aesthetic knowing in nursing:
– “That aspect of knowing that connects with deep
meanings of a situation and calls forth inner creative
resources that transform experience.”
• Rehearsing
• Envisioning
• Integrating aesthetic knowledge into nursing process is
important
– Result: richness, appreciation of practice of nursing
as art as well as science
Copyright © 2010 Wolters Kluwer Health | Lippincott Williams & Wilkins
Personal Knowledge
• “Person’s individualized and subjective ways of learning,
storing, retrieving information about the world”
• “Pattern of personal knowing refers to the quality and
authenticity of the interpersonal process between each
nurse and each [client]”
– Experiential knowing
– Interpersonal knowing
– Intuitive knowing
Copyright © 2010 Wolters Kluwer Health | Lippincott Williams & Wilkins
Ethical Knowledge
• Obligation, “what ought to be done”
• Theoretical/ethical knowledge
– Intellectual conception of what is good, right
– Organized into concepts, propositions formulated into
judgments, rules, principles, theories
– Moral action
– Personal moral
– Situational knowledge
Copyright © 2010 Wolters Kluwer Health | Lippincott Williams & Wilkins
Ethical Knowledge (cont’d)
• Biomedical ethics
– Derived from models of patient good, rights-based
notions of autonomy, or social contract of medical
practice
• Nursing ethics
– Should be based on ethic of caring
– Must consider nature of nurse–client relationship
Copyright © 2010 Wolters Kluwer Health | Lippincott Williams & Wilkins
Ethical Knowledge (cont’d)
• Three different perspectives reflecting different point of
view (paradigm) of how to develop nursing knowledge:
– Particulate–deterministic perspective
– Interactive–integrative perspective
– Unitary–transformative perspective
• Different ways of knowing are not judged against one
another
• Comprehensive nursing knowledge must be based on
integration of all ways of knowing
Copyright © 2010 Wolters Kluwer Health | Lippincott Williams & Wilkins
The Development of Nursing Science
• Defining nursing science poses challenge
• Attaining clear definition of nursing science would provide
foundation for profession’s unique body of knowledge
• Failure to articulate nursing’s exact contributions to
health care delivery may place profession at risk
Copyright © 2010 Wolters Kluwer Health | Lippincott Williams & Wilkins
Concepts
• Highly abstract, general “word[s] or phrase[s] that
summarize the essential characteristics or properties of a
phenomenon”
• Four concepts accepted as central to discipline of
nursing:
– Human beings
– The environment
– Health
– Nursing
Copyright © 2010 Wolters Kluwer Health | Lippincott Williams & Wilkins
Concepts (cont’d)
• Five conceptualizations of caring have been identified:
– Human trait
– Moral imperative
– Affect
– Interpersonal interaction
– Therapeutic intervention
Copyright © 2010 Wolters Kluwer Health | Lippincott Williams & Wilkins
Concepts (cont’d)
• Nursing: highly complex, has various specialty areas of
practice, attaining single definition for nursing concepts is
extremely difficult
Copyright © 2010 Wolters Kluwer Health | Lippincott Williams & Wilkins
Theories
• Communicate links or relationships among concepts in
organized, coherent, systematic way and vary in levels of
abstraction, scope
• Help nurses understand how, why phenomena of nursing
are associated with one another
• Effectiveness in practice directly related to ability to
understand, describe, explain, anticipate human
responses concerning health
Copyright © 2010 Wolters Kluwer Health | Lippincott Williams & Wilkins
Theoretical Frameworks
• Theoretical or conceptual framework:
– “A logical grouping of related concepts or theories”
– Provides guidance, direction for nursing research
endeavors
– Tend to address phenomena more global in nature
• Developing theoretical frameworks for nursing ensures
practice that considers complex nature of professional
practice
Copyright © 2010 Wolters Kluwer Health | Lippincott Williams & Wilkins
Models for Nursing
• Nursing scientists proposed individual, distinctive models
about interrelationships of concepts that form nature,
processes of nursing
– Based on empirical observation, intuitive insights, or
deductive reasoning “that creatively combine[s]
ideas from several fields of inquiry”
Copyright © 2010 Wolters Kluwer Health | Lippincott Williams & Wilkins
Models for Nursing (cont’d)
• Nursing conceptual models identify interventions that
nurses use in practice while explaining four central
concepts of nursing:
– Human beings
– The environment
– Health
– Nursing
Copyright © 2010 Wolters Kluwer Health | Lippincott Williams & Wilkins
Summary and Significance to Practice
• Nurses
– Use variety of methods of knowing when providing
professional nursing services
– Rely on personal, ethical knowing to make effective
clinical judgments, decisions
• Nursing scholars
– Have general agreement on central concepts of
discipline of nursing
Copyright © 2010 Wolters Kluwer Health | Lippincott Williams & Wilkins
Summary and Significance to Practice
(cont’d)
• Central concepts
– Help describe phenomenon of professional nursing
practice
– Guide nurses
• Clinical practice
• Research endeavors
• Educational programs

Answer

D. Callista Roy’s Adaptation Model

Rationale: Roy’s Adaptation Model specifies
that the purpose of nursing is promoting a
human being’s adaptation, the process and
outcome by which thinking and feeling human
beings use conscious awareness and choice
to create human and environmental
integration. It integrates adaptation with
stimulus and coping.

The Link Between Theory
and Knowledge Development



Nursing knowledge is theoretical and
practical.
The goals of theoretical knowledge are to
stimulate thinking and create a broad
understanding of the “science” and practices
of the nursing discipline.
Experiential knowledge, or the “art” of
nursing, is based on nurses’ experiences in
providing care to patients.
