Theory
An abstraction that purports to account
for or explain phenomena
• Classical theory—An abstract
generalization that systematically explains
relationships among phenomena
• Descriptive theory—A theory that
thoroughly describes a phenomenon, based
on rich observations of it

Theory (cont’d)
• Grand theory—A theory that attempts
to explain large aspects of human
experience
• Middle-range theory—A theory that
focuses on a specific aspect of human
experience

Conceptual Models
• Deal with abstractions, assembled in a
coherent scheme
• Represent a less formal attempt than
theories to explain phenomena
• Do not have formal propositions about
relationships among phenomena
Copyright © 2008 Wolters Kluwer Health | Lippincott Williams & Wilkins
Framework
• Theoretical framework (based on
theory)
• Conceptual framework (based on a
conceptual model)

Commonalities Between Theories and
Conceptual Models
• Use concepts as building blocks
• Require conceptual definitions of key
concepts
• Can be depicted in a schematic model
• Are created by humans
• Are developed inductively

Commonalities Between Theories and
Conceptual Models (cont’d)
• Cannot be proven—they are supported
to greater or lesser degrees
• Can be used to generate hypotheses
• Can serve as a stimulus to research

5-Step Process for Developing Conceptual
Definitions
1. Develop a preliminary definition
2. Do an in-depth literature review
3. Identify exemplary cases
4. Map the concept’s meaning
5. State the revised conceptual
definition

Conceptual Models of Nursing
Formal explanations of what nursing practice is
Four concepts central to models of nursing:
• Person
• Environment
• Health
• Nursing
Copyright © 2008 Wolters Kluwer Health | Lippincott Williams & Wilkins
Conceptual Models Used Frequently by
Nurse Researchers
Conceptual models of nursing:
• Roy’s Adaptation Model
• Orem’s Self-Care Model
Other models developed by nurses:
• Pender’s Health Promotion Model (HPM)
• Mishel’s Uncertainty in Illness Theory

Conceptual Models of Nursing Used by
Nurse Researchers
Copyright © 2008 Wolters Kluwer Health | Lippincott Williams & Wilkins
Examples of Non-Nursing Models by Nurse
Researchers
• Becker’s Health Belief Model (HBM)
• Lazarus and Folkman’s Theory of Stress
and Coping
• Bandura’s Social Cognitive Theory
• Ajzen’s Theory of Planned Behavior (TPB)

The Use of Theories or Models in
Quantitative Research
• Testing a theory
• Testing two competing theories
• Using a theory/model as an organizing
structure
• Fitting a problem into theory
• Developing an original theory/model

Theories in Qualitative Research
• Substantive theory—conceptualizations of the
target phenomena
• Theory embedded in a research tradition
 Grounded theory (symbolic
interactionism)
 Ethnography (cultural theories: ideational
and materialistic)
 Phenomenology (phenomenological theory
of human experience)

Examples of Questions to Assess a
Model or Theory
• Clarity: Are key concepts defined? Are
definitions clear?
• Complexity: Is the theory sufficiently
rich? Overly complex?
• Grounding: Is there an empirical basis for
the theory?

Examples of Questions to Assess a Model
or Theory (cont’d)
• Appropriateness: Are key concepts within
the domain of nursing?
• Importance: Will testing the theory
contribute to nursing’s evidence base?
• Competition: Are there theories that
better explain the key phenomenon?
