Hallmark Features A focus on foundational knowledge related to professional nursing Includes nursing history, nursing theory, ethics, and legal aspects, etc. An overview of professional nursing roles, issues, and changes in the profession Discusses nurses as healthcare providers, learners and teachers, and leaders
4
Challenges and Opportunities
Traditional gap between academia and practice Nursing theory considered ethereal and unrelated to the real world of nursing by practicing nurses Theory development is foundation for knowledge development Drawn from multiple and diverse approaches Allows application to what is the best fit Does this best serve the profession?
5
Learning Objective 6.1 Describe the nature of knowledge development.
6
Worldviews and Knowledge Development
Theory A system of ideas proposed to explain something Improves practice by describing, explaining, predicting, and controlling phenomena Guides practice, education, and research Provides professional autonomy Study helps develop analytical skills
7
Worldviews and Knowledge Development
Nursing theory Not part of nursing education when first developed Until the 1950s, practice based on principles and traditions Florence Nightingale first proposed nursing knowledge as different and distinct from medical knowledge
8
Worldviews and Knowledge Development
Different theories represent different worldviews Individuals who think and see the world in different ways create theories Provide contrasting paradigms (structures for organizing theory) Provide different traditions and approaches to science and knowledge development
9
Worldviews and Knowledge Development
Positivist approach paradigm 18th-century Age of Enlightenment Natural law Linear Cause and effect using experimental research methods General to specific
10
Worldviews and Knowledge Development
Constructivist paradigm Science is embedded in time because truth is dynamic Reality not fixed Truth is found in one’s experiences Research uses naturalistic settings and observational methods Specific to general
11
Worldviews and Knowledge Development
Categories of theories Philosophy Nature of things, aims to provide broad understanding Nursing models Form interrelationships among concepts and definitions to provide organized perspective
12
Worldviews and Knowledge Development
Categories of theories Grand theory (nursing theories) General, broad, and complex Middle-range theory Narrower focus, refined through series of studies See Table 6−1

58
Table 6-2 Comparison of Caring Models and Theories
Mayeroff Leininger Roach Watson Boykin and Schoenhofer Perspective on caring To care for another person is to help that person grow and actualize. Care is the essence of nursing. Caring is the human mode of being. Individual healing processes can be strengthened through authentic caring relationships. Caring is an essential feature and expression of being human. Unique focus Major ingredients of caring are knowing, alternating rhythms, patience, honesty, trust, humility, hope, and courage. Caring is inextricably linked with culture. Caring is not unique to nursing but is unique in nursing. Caritas processes are based on the carative factors. A transpersonal caring relationship is established through the processes of caring and healing and being in an authentic relationship, in the moment. Nurturing involves persons living and growing in caring.
59
Table 6-2 (Continued) Expression in nursing
It assists the nurse in developing a sense of self as a caring person. Provide culturally acceptable care. Professionalization of caring is expressed through the 5 C's of caring: Compassion Competence Confidence Conscience Commitment Watson's theory stresses the importance of the lived experience not only of the client but of the nurse. Both the nurse and the client come together in a caring moment. Caring is the intentional and authentic presence of the nurse with another who is recognized as a person living and growing in caring.

Four contexts of experience Physical Psychospiritual Social Environmental With this theory nurses identify unmet comfort needs of clients
67
Mishel’s Uncertainty in Illness Theory
Theory developed from information-processing model used by psychology Uncertainty is the inability to determine meaning of illness-related events when decision maker can’t assign value to objects or events
68
Mishel’s Uncertainty in Illness Theory
Assumptions of this theory are Uncertainty is a cognitive state Uncertainty is neutral until interpreted as desirable or aversive Adaptation is the desired outcome The relationships among illness move from uncertainty to adaptation
69
Mishel’s Uncertainty in Illness Theory
Assumptions of this theory are People function in far-from-equilibrium states Major fluctuations in far-from-equilibrium states enhance receptivity to change Fluctuations result in repatterning
70
