What is a theory?
A set of concepts,definitions, relationships,and assumptions thatproject a systematic viewof a phenomena
It may consist of one ormore relatively specificand concrete conceptsand propositions thatpurport to account for, ororganize somephenomenon (Barnum,1988)

What are the components of atheory?
Concepts – ideas and mentalimages that help to describephenomena (Alligood andMarriner-Tomey, 2002)
Definitions – convey thegeneral meaning of theconcepts
Assumptions – statementsthat describe concepts
Phenomenon – aspect ofreality that can be consciouslysensed or experienced(Meleis, 1997).

What is a paradigm?
A model thatexplains the linkagesof science,philosophy, andtheory accepted andapplied by thediscipline (Alligoodand Marriner –Tomey, 2002)

Purposes of nursing theory

What are the purposes of nursingtheory?
It guides nursingpractice andgenerates knowledge It helps to describe
or explain nursing Enables nurses to
know WHY they aredoing WHAT theyare doing

Types of nursing theories
Grand theories – broadand complex
Middle-range theories-address specificphenomena and reflectpractice
Descriptive theories –first level of theorydevelopment
Prescriptive theories –address nursinginterventions and predicttheir consequences

Why on earth do we studynursing theory?
Everyday practice enrichestheory
Both practice and theory areguided by values and beliefs
Theory helps to reframe ourthinking about nursing
Theory guides use of ideasand techniques
Theory can close the gapbetween theory and research
To envision potentialities(Gordon, Parker, & Jester,2001)

“The study and use ofnursing theory in nursing
practice must have roots inthe everyday practice of
nurses (Gordon, Parker, andJester, 2001).

So how do nurses use theory ineveryday 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)

Components/Elements oftheory
1.Purpose “Why is the theoryformulated”
3-22Copyright 2004 by Delmar Learning, a division of Thomson Learning, Inc.
2.Concepts are building blocks oftheory – ideas, mental images of a
phenomenon, an event or object thatis derived from an individual’s
experience and perception
Components/Elements oftheory
3.Has a major concept like nursing,person, health or environment.

4. Definitions give meaning toconcepts which can either be
descriptive or procedural (stipulate-use of term within the theory)
Components/Elements oftheory
Propositions areexpressions of
relational statementsbetween and amongthe concepts. It can
be expressed asstatements,
paradigms or figures. AKA as theoretical
assertions
Assumptions-accepted “truths”that are basic andfundamental to the
theory. Or valueassumptions wherewhat is good or right
or ought to be.

Characteristics of a Theory
1. Systematic, logical and coherent(orderly reasoning,no contradictions)
2. Creative structuring of ideasmental images of one’s experiences andcreate different ways of looking at a particularevent or object.
3. Tentative in nature ( change over time orevolving but some remain valid despitepassage of time)

How does a theory develop?
3. Research theory or inductive methodMust evolve from research findings or
empirical evidence.
4. Theory research theorytheories developed by other disciplines
are utilized but given unique nursingperspective. Original theory examinedand given a new research findings.

TERMINOLOGY
METAPARADIGM- Most abstract level of knowledge. In
nursing this is main concepts thatencompasses the subject matter and thescope of the discipline
- Central concepts of person, environment,health and nursing

TERMINOLOGY
Philosophy- Knowledge level which specifies the
definitions of the metaparadigm conceptsin each of the conceptual models ofnursing.
- Nightingale is considered philosophicalapproach
- Out of these philosophies theory maybeformalized

Conceptual models
Frameworks or paradigms that provide abroad frame of reference for thesystematic approaches to thephenomena with which the discipline isconcerned. -different views nursing like Roy focuses
on adaptation, King on interaction andAbdellah on interventions

Uses of theory
1. Theory guides and improve nursingpractice
Theory provides goal for nursing careand with goals, nursing practice isrendered more effective and efficient.theories help to focus the goals, makingnurses more confident about thepractice.

2. Theory guides researchaccording to Meleis, primary use oftheory is to guide research. It validatesand modifies the theory.
3. Theory contributes to the developmentof the disciplines body of knowledge
4. Theory enhances communication
