Introduction to Nursing Theory, History, and Philosophy

Introduction to Nursing Theory and History

• Foundations of Nursing Knowledge:

  • Nursing theory encompasses the history and philosophy of nursing as a science.

  • The module explores the structure of nursing knowledge as it has evolved through various stages.

• History of Nursing Theory:

  • The origin of nursing theory is credited to Florence Nightingale, specifically her emphasis on maintaining a clean and healthy environment to facilitate patient recovery.

  • Nightingale envisioned nursing as a professional career for educated women.

  • Notable historical events include Nightingale organizing care during the Crimean War and the founding of the first nursing school at St. Thomas Hospital in London.

  • The field has evolved from a skill-based vocational role into a professional practice founded on formal education and clinical experience.

• The Apprenticeship Model:

  • This model was characterized by hands-on practice and the following of tradition, as established during the era of Florence Nightingale.

  • It is referred to as the "Practice Era," which preceded the development of formal nursing curricula.

  • During this time, nurses were trained through $2$-year vocational diplomas that focused primarily on practical skills.

The Evolution of Nursing Knowledge: Historical Eras

• Curriculum Era ($1900$ to $1940s$):

  • Major Question: What curriculum content should nurses study to become nurses?

  • Emphasis: Specific courses to be included in nursing programs.

  • Outcomes: The creation of standardized curricula for diploma programs.

  • Emerging Goal: The development of specialized knowledge and the pursuit of higher education.

• Research Era ($1950$ to $1970s$):

  • Major Question: What is the focus for nursing research?

  • Emphasis: Identifying the role of nurses and determining research priorities.

  • Outcomes: This era produced problem studies and studies focusing on the nurses themselves.

  • Emerging Goal: The realization that isolated studies do not yield a unified body of knowledge.

• Graduate Education Era ($1950$ to $1970s$):

  • Major Question: What knowledge is needed for the practice of nursing?

  • Emphasis: Defining an advanced role for nurses and establishing a basis for nursing practice.

  • Outcomes: Recognition that nurses play an important role in healthcare.

  • Emerging Goal: Focusing graduate education specifically on the development of nursing knowledge.

• Theory Era ($1980$ to $1990s$):

  • Major Question: How do these frameworks guide research and practice?

  • Emphasis: Acknowledgment that there are multiple ways to think about nursing.

  • Outcomes: Nursing theoretical works shifted the primary focus of the discipline to the patient.

  • Emerging Goal: Theories began to guide nursing research, practice, and overall discipline development.

• Theory Utilization Era ($21st$ century):

  • Major Question: What new theories are needed to produce evidence of quality care?

  • Emphasis: Nursing theory serves as a guide for research, practice, education, and administration.

  • Outcomes: Use of middle-range theory derived from both quantitative and qualitative approaches.

  • Emerging Goal: Utilizing nursing frameworks to produce evidence-based knowledge for quality patient care.

Nursing Metaparadigms and Professional Significance

• The Nursing Model Paradigms:

  • Person: The recipient of nursing care.

  • Environment: The external and internal factors that affect the person.

  • Health: The state of wellness or illness of the person.

  • Nursing: The specific actions and care provided by nurses to the patient.

• Significance of Nursing Theory:

  • In the early $20th$ century, nursing was not recognized as a profession or an academic discipline.

  • Structural changes and accomplishments over time led to its recognition in both the academic and professional spheres.

• Distinguishing Discipline and Profession:

  • Discipline:

    • Refers to a branch of education or a domain of knowledge.

    • Emphasizes theoretical learning that supports advanced education and practice.

    • Focuses on what nurses know and how that knowledge is applied in clinical decision-making.

    • Centers on the interaction between person, health, and environment as the basis of nursing knowledge.

  • Profession:

    • A specialized field of practice built upon the theoretical knowledge of a discipline.

    • Integrates scientific knowledge with practical skills.

    • Earns respect and recognition for its scholarly and meaningful contributions to society’s health.

Criteria for Professional Status in Nursing

1. Practices using a well-defined and well-organized body of specialized knowledge.

2. Continuously expands its knowledge base and improves techniques of education and service via the scientific method.

3. Entrusts the education of practitioners to colleges and universities.

4. Applies knowledge in practical services that are vital to community welfare.

5. Operates autonomously in the development of professional policy.

6. Attracts individuals with high intellectual and personal standards who are dedicated to service.

7. Strives to compensate nurses through freedom of action, professional growth opportunities, and economic security.

Epistemology and Philosophical Foundations of Science

• Definition of Epistemology:

  • Derived from "episteme" (knowledge) and "logos" (study of).

  • It is the study of knowledge and the justification of beliefs.

  • It is a branch of philosophy concerned with the nature, scope, and acquisition of knowledge.

  • It questions what constitutes knowledge and how the "real" is classified as knowledge.

• Philosophical Foundations:

  • Rationalism:

    • Asserts that knowledge originates from reason and logic rather than sensory experience.

    • Utilizes deductive thinking (moving from general principles to specific instances).

    • Follows a "theory-first" approach, where theories are developed and then tested through research.

    • Example: Predicting that a lack of social support may lead to hospital readmission.

  • Empiricism:

    • Asserts that knowledge is derived from sensory experience (sight, hearing, etc.).

    • Utilizes inductive reasoning (moving from specific observations to general conclusions).

    • Follows a "research-then-theory" approach.

    • Serves as the basis for the scientific method through experimentation and observation.

    • Example: Real-world physical assessments and clinical observations.

The Development of Nursing Science

• Early $20th$ Century Views:

  • Positivism shaped nursing science by emphasizing empirical research and logical analysis.

  • Philosophers were focused on theory while scientists focused on data.

  • The rise of computers enabled more advanced data analysis.

• Late $20th$ Century Views:

  • A shift toward a phenomenological approach, focusing on "lived experiences" and meanings behind phenomena.

  • Scholars challenged positivism, opening the discipline to diverse perspectives.

• Interdependence of Theory and Research:

  • Theory organizes existing knowledge.

  • Research provides the evidence necessary to support, revise, or replace theory.

  • New data can significantly alter established theories.

• Science as a Social Enterprise:

  • Science is a human activity influenced by social, economic, and political factors (e.g., funding, ideology).

  • Progress in nursing is driven by diverse dialogue and the interaction of multiple paradigms.

The Process of Theory Development

• Defining Theory:

  • Etymology: Derived from the Greek word "theoria," meaning "a vision" or "a beholding scene."

  • While often colloquially used to mean a "guess," in science, it implies something that is systematically organized and generally accepted as true.

  • Powers & Knapp Definition: A set of statements that tentatively describe, explain, or predict relationships among concepts organized as an abstract representation of a phenomenon.

  • Bodie & Chitty Definition: An internally consistent group of relational statements (concepts, definitions, propositions) that present a systematic view of a phenomenon for description, explanation, prediction, and control.

• Categories of Concepts:

  • Abstract: Independent of a specific time and place.

  • Concrete: Linked to a specific time or place.

  • Discrete: Belonging (or not belonging) to specific categories of phenomena.

  • Continuous: Gradations of a phenomenon across a continuum or various degrees.

  • Theoretical Definitions: Establish dictionaries-style meanings.

  • Operational Definitions: Explain how concepts are used or measured within the specific context of the phenomenon.

Concept Building and Relational Statements

• $10$ Phases of Concept Building:

  1. Write a meaningful practice story.

  2. Name the central phenomenon in that story.

  3. Identify a theoretical lens for viewing the phenomenon.

  4. Link the phenomenon to existing literature.

  5. Gather a story from someone who has lived the phenomenon.

  6. Reconstruct the shared story into a mini-saga capturing the message.

  7. Identify core qualities of the phenomenon.

  8. Use core qualities to create a definition.

  9. Create a model of the phenomenon.

  10. Write a mini-synthesis integrating the phenomenon with a population to suggest research directions.

• Relational and Theoretical Statements:

  • Relational Statements: Define relations among concepts.

  • Theoretical Statements: Link concepts to one another for analysis.

  • Operational Statements: Link concepts to specific measurements.

• Linkages and Ordering:

  • Linkages of Theoretical Statements: Provide the rationale for why concepts are connected (adds plausibility).

  • Linkages of Operational Statements: Rationale for how variables are linked (permits testability).

  • Organization: Grouping terms into primitive and derived terms to eliminate overlap (tautology) and inconsistency.

Scientific Laws, Theories, and Hypotheses

• Scientific Laws: Simple, true, universal, absolute statements describing natural phenomena based on repeated experiments. (Example: Gravity—a ball always falls to the ground).

• Theory: More complex than a law; updated through the scientific method and supported by strong evidence.

• Hypothesis: An educated guess based on observations; it is not yet proven but can be tested to guide discussion or study. (Example: "Smoking leads to lung cancer.")

Florence Nightingale’s Environmental Theory

• Historical Context:

  • Known as the "Mother of Modern Nursing."

  • Nightingale ($1859-1992$—as cited) authored Notes on Nursing, focusing on environmental manipulation.

  • The Crimean War (started in March $1853$ between Russia and Turkey) served as her primary field of practice.

  • Returned to England in $1856$ as a national heroine and published Notes on Nursing and Notes on Hospitals in $1859$.

• Theory Definition: Nursing is the art of utilizing the patient's environment to support their recovery.

• Metaparadigms in Nightingale’s Theory:

  • Nursing: Comparable to motherly instincts.

  • Person: The recipient of care.

  • Health: Living up to one's potential to the fullest extent.

  • Environment: Elements external to the person (food, flowers, verbal/non-verbal interactions).

Jean Watson’s Theory of Transpersonal Caring

• Background:

  • Born in Welch, West Virginia (youngest of $8$ children).

  • Developed the theory while Assistant Dean at the University of Colorado.

  • Evolved from $11$ curative factors into $10$ carative factors/caritas processes.

• Books:

  1. Nursing: The Philosophy and Science of Caring ($1979$): Introduced the $10$ carative factors and the concept of "caritas" (loving attention).

  2. Nursing: Human Science and Human Care – A Theory of Nursing ($1985$): Addressed conceptual problems in nursing.

• Transpersonal Caring Relationship:

  • A union with another person with high regard for their whole being.

  • Uses "carative" instead of "curative."

• $10$ Elements of Carative Factors:

  1. Humanistic-altruistic system of value (loving kindness/equanimity).

  2. Faith-hope (sustaining deep belief).

  3. Sensitivity to self and others (compassion).

  4. Helping-trusting, human care relationship (authenticity).

  5. Expressing positive and negative feelings.

  6. Creative problem-solving caring process (artistry).

  7. Transpersonal teaching-learning (genuine engagement).

  8. Supportive, protective, or corrective environment (healing at all levels).

  9. Human needs assistance (intentional caring consciousness).

  10. Existential-phenomenological-spiritual forces (attending to life-death dimensions).

• Metaparadigms in Watson’s Theory:

  • Nursing: Professional, personal, scientific, aesthetic, and ethical care transactions.

  • Person: A unity of Mind, Body, and Soul.

  • Health: Harmony within the spheres of the person (illness is subjective turmoil).

  • Environment: A caring attitude is transmitted by the culture of the profession as a way of coping with the environment.
