Understanding Theory and Research
Frameworks

1


Theory’s Role in Research





Research is based on theory.
Theory is the initial inspiration for research
study.
Research helps answer the question, “Was
my theory correct?”

Frameworks and Theories







A framework is a brief explanation of a theory
or portions of a theory to be tested in a study.
A theory is abstract rather than concrete.
It focuses on the general.
The framework may be implicit or implied.

3


Conceptual Models







These are more abstract than theories.
They explain phenomena of interest and
reflect a philosophical stance.
They cannot be tested via research.
They may guide further qualitative studies.
Operational definitions are often found in
these models.

Elements of a Theory








Concepts: Abstractly describe and name an object,
idea, or phenomenon, thus providing it with a
separate identity or meaning
Conceptual definition: More comprehensive than a
dictionary definition; includes associated meanings a
word may have
Relational statement: Clarifies the type of
relationship that exists between or among concepts
Map or model: Graphically shows the
interrelationships of the concepts and relational
statements

5


Middle Range Theories





Less abstract and narrower in scope than
conceptual models
Emerge from review of studies to build
evidence-based practice related to a clinical
problem

6


Practice and Intervention Theories






Practice theory is prescriptive theory.
Intervention theory is a form of practice
theory.
These theories direct nursing interventions.
Practice theory research develops into
evidence-based practice.

Frameworks




Frameworks explain the theory.
Frameworks give relationships of variables.
This results in the hypothesis, which is
testable.

8


Problems with Frameworks





Inappropriate framework
Disconnected framework
Multiple frameworks
Unidentified framework

9


Select Concepts










Based on relevance to phenomenon of
concern
Must have a concept for every major variable
in study
Examine problem statement for relevant
concepts
Include concepts from purpose statement if
appropriate
Are also called constructs

10



Sources of Conceptual Definitions


Existing theoretical works
Must be used if proposition from theory being
tested
 Always desirable when available
 Should be directly quoted (if possible) and cited




Published concept analyses

11


Sources of Conceptual Definitions
(cont’d)






Previous studies using the concept
Publications describing instrument

development
General literature
Performing a concept analysis

12


Critiquing a Study Framework








Concepts are linked with variables that are
measured.
Concepts are represented in hypotheses,
research questions, or objectives.
The hypotheses, research questions, or
objectives are tested statistically.
The hypotheses, research questions, or
objectives emerge from framework
propositions.

13


Critiquing a Study Framework (cont’d)




Look for comments connecting findings to
specific elements of the framework.
Search for comments discussing the
implications of findings in terms of truth or
falsity of framework propositions.

14


Critiquing a Study Framework (cont’d)






Are the findings for each hypothesis,
question, or objective consistent with those
proposed by the framework?
If the findings are not consistent with the

framework, was the methodology adequate to
test the hypothesis, question, or objective?
Are the findings consistent with those of other
studies using the same framework (or testing
the same propositions)?

15


Developing Relational Statements


When possible, they should be obtained from
existing theoretical works and the source
cited.







Called an existence statement

Otherwise, relationships must be proposed by
researcher.
Also called propositions
Evidence for validity of statement should be

provided.

Copyright © 2011 by Saunders, an imprint of Elsevier Inc.

16


Critique Guidelines for Statements










What statements are expressed within the
publication?
Are all the study concepts included within the
statements?
Do the statements reflect back on the Title and
Purpose of the study?
Are statements expressed as both propositions and
hypotheses (or research questions)?
Are one or more statements being tested by the
study design?

17


Conceptual Maps







Show interrelationship between concepts and
statements
Summarize and integrate what is known
about a phenomenon more clearly than do
literary explanations
Include all major concepts in a theory
Use arrows to explain linkages

Copyright © 2011 by Saunders, an imprint of Elsevier Inc.

18


Frameworks for Physiological Studies







Derived from physics, physiology, and
pathophysiology
Theoretical relationships may be considered
facts rather than theories.
Propositions can be developed and tested
using these laws and principles.

Copyright © 2011 by Saunders, an imprint of Elsevier Inc.

19


Frameworks Based on Middle
Range Theories








Limited scope
Particular substantive focus
Contain limited number of concepts
Focus on limited aspect of relationship
Sufficiently general to be interesting
Empirically testable

Consolidated into wide-range theories
