This document provides an introduction and overview of nursing theory. It defines key concepts such as theory, paradigm, domain, and components of a theory. It describes the purposes of nursing theory as guiding nursing practice and generating knowledge. Nursing theory can be categorized into grand, middle-range, descriptive, and prescriptive theories. The document emphasizes that nursing theory should be rooted in everyday nursing practice and discusses how nurses can utilize theory in practice. It also notes that nursing draws from non-nursing theories and that theory provides direction for nursing research.

1. INTRODUCTION TO…

2. What 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,
1988)

3. What 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).

4. What 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)

5. What 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

6. How 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

7. Purposes of nursing theory

8. What 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

9. Types 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

10. Why 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)

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).

12. So 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)

13. How do student nurses begin to
use nursing theory?
• By asking yourself
two very important
questions…..

14. Student nurse questions
• What is the nature of
knowledge needed for the
practice of nursing?
• What does it mean to me
to practice nursing?

15. Nursing also utilizes non-nursing
theories

16. Commonly used non-nursing
theories
• Systems theory
• Basic Human Needs
theory
• Health and Wellness
Models
• Stress and Adaptation
• Developmental
Theories
• Psychosocial
Theories

17. What 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

18. Current trends that influence
nursing theory
• Medical science
• Nursing education
• Professional nursing
organizations
• Evolving research
approaches
• Global concerns
• Consumer demands
• Technologies

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.”
