Notes on Theoretical Nursing Models and Theory Categories

Identify domain and goals of nursing.
Provide knowledge for nursing administration, practice, education, and research.
Guide research and curriculum development.
Establish criteria for measuring quality of care.
Provide systematic structure for nursing activities.

Abstract, broad, and complex, providing a structural framework for general ideas about nursing.
Address the question "What is nursing?" and focus on the whole of nursing.
Address nursing metaparadigm components: person, nursing, health, environment.
Example: Dorothy Johnson's Behavioral System Model focuses on restoring equilibrium to the behavioral system.

More limited in scope and less abstract; address specific phenomena (e.g., uncertainty, comfort).
Often developed from research, practice, or other disciplines.
Example: Kolcaba's theory of comfort guides nurses in meeting physical, psychospiritual, environmental, and sociocultural comfort needs.

Also known as situation-specific theories, narrow in scope and focus.
Guide care for a specific patient population at a specific time (bring theory to the bedside).

Hierarchy (most to least abstract): Metatheory $\to$ Grand theories $\to$ Middle-range theories $\to$ Practice theories

Descriptive theories: Describe phenomena and identify circumstances of occurrence; help explain patient assessments.
Prescriptive theories: Address nursing interventions, guide practice change, and predict consequences.

Essential for advancing nursing as a practice-oriented profession, deriving knowledge from sciences, experience, and standards.

Explain phenomena specific to the discipline that developed them, but are applied in nursing.
Examples:
- Piaget's theory of cognitive development: aids pediatric nurses in designing therapeutic play.
- Knowles' adult learning theory: helps plan discharge teaching.

Many nursing theories are based on systems theory; the nursing process is a system with a specific purpose to guide clinical judgment and deliver person-centered care.
Nursing Process Components (as a system):
- INPUT: Patient interaction with the environment (Psychological, Physiological, Developmental, Sociocultural, Environmental, Spiritual domains).
- OUTPUT: Patient's health status for returning to the environment.
- FEEDBACK: Outcomes reflecting patient responses to interventions, family responses, and consultations.
- CONTENT: Product and information obtained from the system (e.g., skin care needs for impaired bed mobility).

Human needs (Maslow's Hierarchy): Explains that needs motivate human behavior, prioritizing physiological and safety needs before higher-level psychological, sociocultural, developmental, and spiritual needs.
Stress/adaptation: Humans adapt to threats to maintain function; requires nursing interventions to support coping.
Developmental: Humans have common patterns of growth and development; guides understanding of life-span changes.

Henderson's theory (Grand): Nurses assist patients with 14 basic activities (e.g., breathing, eating, hygiene) until they can meet these needs themselves.
Johnson's Behavioral System (Grand): Nurses assist patients (perceived as whole, more important than disease) to restore balance and meet needs in their behavioral system.
