Nursing Theories and Frameworks

1
Nursing Theories and Frameworks
2
Learning Objectives

• Compare inductive and deductive reasoning
• Differentiate between conceptual and theoretical
  frameworks
• Describe how a framework guides research
• Differentiate between conceptual and operational
  definitions
• Describe the relationship between research and
  theory and practice

3
Learning Objectives

• Differentiate between grand and midrange nursing
  theories
• Describe the criteria for critique of theoretical
  or conceptual frameworks in the nursing literature

4
Approaches to Science

• Inductive Reasoning

• Deductive Reasoning

5
Ladder of Abstraction

• Worldview
• Frameworks
• Theories
• Concepts
• Variables

6
Concept

• Definition
• an abstraction
• creates an image of an idea we want to share
• representations of particular aspects of human
  behavior and characteristics
• Pain
• Coping
• Grief
• Resilience

7
Identify the Concepts

• A theoretical model was developed and tested to
  explain the effects of learned helplessness
  self-esteem and depression on the health
  practices of homeless women. (Flynn 1997)
• prevalence and consequences of verbal abuse of
  staff nurses by physicians were examined in the
  context of Lazarus stress-coping model.
  (Manderino Berkey 1997)

8
Construct

• Similar to a concept in that it refers to an
  abstraction
• Different from a concept in that it is
  deliberately invented (constructed) by
  researchers for a scientific purpose
• Health locus of control
• Self-care in Orems model

• Concept and construct are sometimes used
  interchangeably although a construct often refers
  to a more complex abstraction than a concept

9
Terminology

• Conceptual framework
• Structure of concepts and theories pulled
  together like a map for the study

• Theoretical framework
• A structure of concepts that exists in the
  literature a ready-made map for the study
• Provide a theoretical rationale for the
  development of hypotheses

10
Conceptual Framework

• Explains how the variables in your study are
  expected to relate to each other
• A conceptual framework is used when the
  literature does not contain a specific theory
  that explains the relationship between study
  variables.

11
Theoretical Framework

• Used when the variables have been studied before
  and have been found to be related to one another
• At Level I there may be no framework based on
  existing literature. This establishes a rationale
  for the need to conduct such a study.
• At Level II you can provide a conceptual
  framework from literature on the variables of
  your study.
• Level III studies always have theoretical
  frameworks.

12
What does a framework do

• Provides direction for the study by providing an
  organized set of ideas/variables and their
  relationships
• Reveals conceptual and operational definitions
• Guides what data is to be collected and analyzed

13
Terminology

• Conceptual definition like a dictionary
  definition conveys the general meaning of a
  concept
• Operational definition specifies how the
  concept will be measured (i.e. what instruments
  will be used)

Appendix B Van Cleve et al. 2004
15
Terminology

• Theory set of interrelated concepts that
  provides a systematic view of a phenomenon
• OR Theory is an abstract generalization that
  presents a systematic explanation about the
  relationships among phenomena
• Theory guides practice and research practice
  enables testing of theory and generates questions
  for research research contributes to
  theory-building and establishing practice
  guidelines. LB-W H p. 113

16
Nursing Theory

• Many theory/concepts Borrowed from other
  disciplines
• Nursing Theories
• Grand
• Mid-range
• Microrange

17
Nursing Theories

• Conceptual structure that organizes practice and
  research into ideas central to the discipline
• Nursing theories are reservoirs in which
  findings related to nursing concepts such as
  comfort healing recovering mobility rest
  caring enabling fatigue and family care are
  stored. Meleis (1997)

18
Grand Theories

• Conceptual structures that include views on
  person health and environment to create a
  perspective of nursing
• Historically important
• Guides discipline of nursing today
• Abstract level
• Address a phenomena of concern to nursing from a
  different perspective

19
Grand Theories

• Imogene King 1981 Open Systems Model
• Madeleine Leininger 1991 Theory of culture
  care diversity and universality
• Dorothea Orem 1985 Self-care Model
• Sr. Callista Roy 1984 1991 Adaptation Model
• Jean Watson 1999 Theory of Caring
• These models are broad formal explanations of
  what nursing discipline is according to the
  developers point of view

20
Midrange Theories

• Are moderately abstract but composed of concepts
  that are measurable
• More focused than grand theories
• Have a stronger relationship with research and
  practice
• Lie between everyday working hypotheses and
  grand theoriesMerton (1968)

21
Midrange Theories

• Tend to focus on concepts of interest to nurses
• Pain empathy grief self esteem hope comfort
  dignity quality of life
• Some midrange theories have their basis in grand
  theories
• Midrange theory of self-care deficit grew out of
  Orems (1980) grand theory of self care

22
Midrange Theories

• Categorized by level of abstraction
• High middle and low
• K. Kolcaba Theory of Comfort
• R. Mercer Maternal Role Attainment
• AACN The Synergy Model for Patient Care

23
Microrange Theory

• Closely related to midrange theories
• More narrow in scope
• Described at the level of hypothesis
• Questions/ hypotheses derived from practice

24
Critique Criteria

• Is the theoretical or conceptual framework
  clearly identified
• Is the framework consistent with a nursing
  perspective
• Is the framework appropriate to guide research on
  the topic
• Is there logical connection between the
  framework concepts and the measurement

25
Critique Criteria

• Are the concepts clearly and operationally
  defined
• Was sufficient literature reviewed to support the
  proposed relationships
• Is there a logical link between the framework
  the study concepts and the methods of
  measurement
