Introduction to Nursing Theories

An Introduction to Nursing Theories

Nursing theories are essential to nursing education, practice, and patient care. Developed over centuries, these theories have shaped the nursing field as we know it today.

This guide explores the definition of nursing theory, the practitioners of these theories, the various levels and concepts within nursing theory, and highlights notable theories and theorists who have significantly influenced modern nursing.

What Is Nursing Theory?

Nursing theory can be defined as a set of frameworks and principles guiding the nursing profession and practice. Rooted in evidence and research, nursing theory provides a foundation for sound decision-making in nursing.

As highlighted by the Nordic College of Caring Science, nursing theory explains what nurses do for patients and why they do it, helping them deliver optimal patient care.

According to American Nursing History, Florence Nightingale is recognized as the first nursing theorist and is often referred to as “the founder of modern nursing.” Her Environmental Theory, which emphasizes the importance of a patient’s environment in their recovery, remains influential today.

Nursing theories continue to evolve and emerge as they are practiced and tested. In nursing education, students learn these theories to ensure they can provide the most effective and appropriate care to their patients.

Who Utilizes Nursing Theory?

Nursing theories are integral to the practice of many professionals within the nursing field. These theories are learned during formal education and are applied throughout their careers. Nurse researchers and educators heavily rely on these theories as well, incorporating them into university nursing programs through dedicated courses or by integrating them within the curriculum.

A Master of Science in Nursing (MSN) program, for instance, might include a course on theoretical practice, examining the historical, social, and political factors influencing healthcare development. Courses on family development might explore theories relevant to family-centered nursing care.

In research, nursing theories are tested and evaluated to draw conclusions about their efficacy, aiding researchers in making recommendations for better practices. These theories also provide a foundation for new trends in nursing, allowing researchers to compare past results with current developments.

Levels of Nursing Theory

Nursing theories are generally categorized into three levels: grand nursing theories, middle-range nursing theories, and practice-level nursing theories. Each level varies in specificity and abstraction.

1. Grand Nursing Theories: These are the most abstract and broadest theories, providing a general framework for nursing care applicable to various environments and situations. For example, Ida Jean Orlando-Pelletier’s Deliberative Nursing Process Theory focuses on the interaction between nurse and patient and the nursing process to improve outcomes.
2. Middle-Range Nursing Theories: These theories are more specific than grand theories but still broader than practice-level theories. They aim to explain, describe, or predict particular issues in clinical nursing practice. Imogene King’s Theory of Goal Attainment, for example, examines how nurses and patients can set and achieve life goals through communication and actions.
3. Practice-Level Nursing Theories: These are the most specific theories, tailored to defined patient populations and specific times. They draw upon elements from grand and middle-range theories to provide specific frameworks for nursing interventions. For instance, a nurse working with a maternal patient might combine elements from the Maternal Role Attainment Theory by Ramona Mercer and the Life Perspective Rhythm Model by Dr. Joyce Fitzpatrick.

Key Concepts of Nursing Theory

Nursing theories often focus on four main concepts or metaparadigms: person, environment, health, and nursing. These metaparadigms serve as a framework for developing conceptual models in nursing theory.

1. Person: This refers to the patient, who may be an individual, family, or community. Nursing theories emphasize considering individual characteristics and applying a human-focused care strategy, incorporating empathy and compassionate communication.
2. Environment: The setting where nursing care is provided, affecting both patient healing and nursing team morale. Environmental factors such as noise levels, lighting, and access to nature are considered, extending beyond healthcare settings to include the patient’s everyday life and social experiences.
3. Health: This concept covers improving a patient’s immediate health state and maintaining overall well-being. It considers physical, social, moral, and aesthetic aspects, contextualized by the patient’s environment and life stage.
4. Nursing: Refers to the profession and practice of nursing, promoting health and advocating for patients. It involves using scientific theory and evidence-based care while considering human choice and responsibility. For example, nurses might recommend different smoking cessation methods based on a patient’s health and decision-making patterns.

The Importance of Nursing Theory

Nursing theories, grounded in centuries of practice and research, provide insights to modern-day nurses, educators, and researchers. They help contextualize nursing practice, improve patient outcomes, and offer guidance for theory-guided interventions. Studies have shown that these interventions are often successful in enhancing patient care.

Notable Theories and Theorists

1. Florence Nightingale: Pioneer of nursing, known for her environmental theory, which emphasizes factors like fresh air, clean water, and sunlight in patient health.
2. Lewin’s Change Theory: Describes a three-stage model of change involving unfreezing, changing, and refreezing, helping patients adopt healthier behaviors.
3. Virginia Henderson: Developed the Nursing Need Theory, focusing on helping patients achieve independence and meet basic human needs.
4. Dorothea Orem: Created the Self-Care Deficit Nursing Theory, promoting patient autonomy in self-care practices.
5. Jean Watson: Known for the Theory of Caring, which integrates compassion, altruism, and human dignity in nursing care.

Exploring Nursing Theories in Nursing School

Studying nursing involves learning about various theories that have evolved over time to enhance patient care. These theories are applied in healthcare settings to inform and improve nursing practices.
