Theoretical Foundations of Nursing (NURS 308)
WHY LEARN ABOUT THEORIES?
- Foundation to guide practice
- Rationales for implementing care
- Design and implement nursing care
- Theories help describe, explain, predict nursing care measures
- Nightingale: environment free of clutter, soiled linens, excess noise
- Orem: self-care (Self-Care Deficit Nursing Theory – SCDNT)
WHAT IS THEORY?
- Explains concepts, relationships, outcomes
- Metatheory: relationships and components of a discipline
- Nursing theory: addresses an aspect of nursing
- Theory: term, description, label that describes an idea or response to an intervention or situation
- Phenomenon: general meaning of concepts; theoretical, conceptual, operational
- Definitions: statements accepted as truth, based on values and beliefs “taken for granted”
- Assumptions: thought or idea, either abstract or concrete, put into words to describe a specific phenomenon
- Concepts: building blocks of theory; ideas or phenomena that can be defined and studied
DOMAIN OF NURSING
- Domain: perspective of a profession or discipline
- Includes subject, central concepts, values and beliefs, phenomena of interest, and central problems
- Domain of nursing includes nursing theory, history, education, research, and practice
- Paradigm: pattern of beliefs
- Conceptual framework: organizing structure to promote visualization of subject matter
- Four elements: Person, Health, Environment, Nursing
- Person: state of being, dynamic, as defined by the individual receiving care
- Health: conditions affecting the person at home, school, work, or community
- Environment: surroundings influencing health; can include social and physical factors
- Nursing: care of ill, disabled, dying; health promotion, disease prevention; acts performed by nurses
EVOLUTION OF NURSING THEORY
- Nightingale as the first theorist
- Curriculum era: 1900s–1940s — emphasis on scientific content, nursing arts, social sciences, pharmacology
- Research era: 1950s–1970s
- Theory era: 1980s–1990s
- Theory utilization: 21st century; emphasis on evidence-based practice (EBP)
TYPES OF THEORY
- Grand theory: abstract, broad in scope; complex; wide applicability
- Middle-range theory: less abstract; narrower scope; more concrete and testable
- Practice theory: situation-specific; highly focused on real-world nursing practice
- Descriptive theories: explain phenomena
- Prescriptive theories: explain and provide explicit guidance to influence practice and predict consequences
- Scope progression: Grand → Middle-range → Practice (increasing specificity and testability)
THEORY-BASED NURSING PRACTICE
- Theory is necessary to advance knowledge and prescribe specific interventions to improve patient outcomes
- Nursing knowledge explains the practice of nursing as distinct from medicine and other health professions
SHARED THEORIES
- Borrowed or interdisciplinary theories explain a phenomenon specific to the discipline that developed the theory
- Examples of theorists whose ideas are used in nursing: Piaget, Erikson, Kohlberg, Knowles
- Systems theory as a basis for the nursing process, organizing and guiding delivery of patient-centered care
- Mapping in nursing process:
- input: data collection
- output: patient’s health status
- feedback: response
- content: nursing process
NURSING THEORIES (Selected Theories and Theorists)
- Nightingale’s Environmental Theory
- Focus: Hygiene, nutrition, sanitation; manage the environment to improve patient outcomes
- Peplau’s Interpersonal Theory
- Preorientation, orientation, working phase, resolution (the stages of the nurse–patient relationship)
- Interpersonal relationships involve the nurse, patient, and family
- Orem’s Self-Care Deficit Nursing Theory (SCDNT)
- Emphasizes patient self-care capacities and the deficits that require nursing support
- Leininger’s Culture Care Theory (Cultural Diversity)
- Focus: Culture influences everything that involves a patient; culturally congruent care
- Note: The slide caption includes a non-substantive line “Pitch deck title” which is not part of the theory content and is not retained as a concept
THEORY AND RESEARCH BUILD SCIENTIFIC KNOWLEDGE BASE
- Theory
- Shapes and defines practice
- Advances knowledge
- Provides a foundation for specific care
- Relationships between components of theory initiate research questions
- Supports safe, comprehensive, individualized, quality care
- Research
- Validates, supports, or modifies theory
- Develops new theories
- Theory-generating
- Evaluates accuracy of described phenomena
- Theory testing
ADDITIONAL NOTES AND CONNECTIONS
- The metaparadigm components (Person, Health, Environment, Nursing) define the scope of nursing and guide what constitutes nursing knowledge and practice
- Paradigms and conceptual frameworks help organize nursing knowledge and visualization of relationships among concepts
- Evolution of nursing theory reflects shifting emphasis from education and arts to evidence-based practice and theory-driven inquiry
- Shared theories demonstrate how interdisciplinary ideas enrich nursing practice and research, highlighting the importance of a pluralistic theoretical foundation
- Ethical and practical implications include culturally sensitive care, patient autonomy (self-care focus), and the nurse–patient–family relationship as central to care delivery
- Foundational principles connect to real-world care: maintaining hygienic environments, supporting patient self-care, addressing cultural needs, and fostering therapeutic nurse–patient relationships
