Trang 1INTRODUCTION TO…
Trang 2What is a theory?
• A set of concepts,
definitions, relationships,
and assumptions that
project a systematic view
of a phenomena
• It may consist of one or
more relatively specific
and concrete concepts
and propositions that
purport to account for, or
organize some
phenomenon (Barnum,
Trang 3What are the components of a
theory?
• Concepts – ideas and mental images that help to describe phenomena (Alligood and Marriner-Tomey, 2002)
• Definitions – convey the general meaning of the concepts
• Assumptions – statements that describe concepts
• Phenomenon – aspect of reality that can be consciously sensed or experienced
(Meleis, 1997).
Trang 4What is a paradigm?
• A model that explains
the linkages of
science, philosophy,
and theory accepted
and applied by the
discipline (Alligood
and Marriner –
Tomey, 2002)
Trang 5What is a domain?
• The view or perspective of the discipline
• It contains the subject, central concepts, values and beliefs, phenomena of interest, and the
central problems of the discipline
Trang 6How does domain relate to
nursing theory?
• Nursing has identified
its domain in a
paradigm that
includes four
linkages:
1) person/client
2) health
3) environment
4) nursing
Trang 7Purposes of nursing theory
Trang 8What are the purposes of
nursing theory?
• It guides nursing practice and
generates knowledge
• It helps to describe or explain nursing
• Enables nurses to
know WHY they are doing WHAT they are
doing
Trang 9Types of nursing theories
• Grand theories – broad
and complex
• Middle-range theories-
address specific
phenomena and reflect
practice
• Descriptive theories –
first level of theory
development
• Prescriptive theories –
address nursing
interventions and predict
their consequences
Trang 10Why on earth do we study
nursing theory?
• Everyday practice enriches theory
• Both practice and theory are guided by values and beliefs
• Theory helps to reframe our thinking about nursing
• Theory guides use of ideas and techniques
• Theory can close the gap between theory and research
• To envision potentialities (Gordon, Parker, & Jester, 2001)
Trang 11“The study and use of nursing theory in nursing practice must have roots
in the everyday practice
of nurses (Gordon, Parker, and Jester, 2001).
Trang 12So how do nurses use theory in
everyday practice?
• Organize patient data
• Understand patient data
• Analyze patient data
• Make decisions about
nursing interventions
• Plan patient care
• Predict outcomes of care
• Evaluate patient
outcomes
(Alligood, 2001)
Trang 13How do student nurses begin to
use nursing theory?
• By asking yourself two very important questions…
Trang 14Student nurse questions
• What is the nature of
knowledge needed for the
practice of nursing?
• What does it mean to me
to practice nursing?
Trang 15Nursing also utilizes non-nursing
theories
Trang 16Commonly used non-nursing
theories
• Systems theory
• Basic Human Needs theory
• Health and Wellness Models
• Stress and Adaptation
• Developmental Theories
• Psychosocial Theories
Trang 17What is the link between nursing
theory and the research
process?
• Theory provides direction
for nursing research
• Relationships of
components in a theory
help to drive the research
questions for
understanding nursing
• Chinn and Kramer
(2004), indicate a spiral
relationship between the
two
Trang 18Current trends that influence
nursing theory
• Medical science
• Nursing education
• Professional nursing organizations
• Evolving research approaches
• Global concerns
• Consumer demands
• Technologies
Trang 19“ Practicing nurses who despise theory are condemned to performing a series of tasks - either
at the command of a physician or in response to
routines and policies.”
