How Nursing Theories Guide Real World Nursing Practice

Theorist Critique: Betty Neuman Nursing Theory

1. Discussion on Betty Neuman nursing theory

As the research that follows shows, Betty Neuman believed the nursing process should address the whole person and all facets impacting health. In sum, Neuman’s theory promotes patient-centered care, looking beyond singular issues to identify potential underlying causes that adversely affect wellbeing across the interconnected aspects of life. The Neuman Systems Model developed by this theorist continues to guide nursing practice and research globally by offering an expansive perspective for assessment, intervention planning, implementation, and evaluation, an outcome that directly relates to the purpose and importance of nursing theories in general as discussed further below.

2. Explore the purpose and importance of nursing theory, to discuss a nursing theory of their choice, and to discuss the application of the theory to practice.

Generally speaking, nursing theory provides an essential framework to guide nursing practice, education, and research. The primary purpose of any nursing theory is to conceptualize the overarching goals, responsibilities, and focus of nurses in delivering high quality patient care, while also offering an organizing structure for generating new knowledge to continually improve outcomes. In this regard, Keles and Eroglu (2024) report that, “The application of theory in [nursing] care can be chosen by nurses as it improves patient outcomes. Furthermore, the use of theories in research to develop nursing knowledge will benefit nursing science while increasing professional autonomy” (p. 11).

Likewise, nursing theories establish useful models for developing effective interventions, quantifying results, and replicating best practices through ongoing research. In addition, the core nursing theories developed over the years also serve as a means to articulating the various philosophical, ethical foundations of the nursing profession’s commitments to the provision of patient-centered care (Ortiz, 2021).

In addition, nursing theories help identify and explain the unique roles nurses play in virtually all types of healthcare environments, clarifying responsibilities and specialization opportunities compared to other clinical roles. By applying nursing theory concepts directly to practice, nurses can gain insights to inform and enhance their critical thinking skills, clinical judgment, and decision justification around evidence-based care tailored to each patient’s needs. The use of theory helps unify nurses under coherent paradigms for what constitutes ideal care while creating opportunities to innovate, measure impact, expand knowledge, and standardize best practices (Ortiz, 2021). In addition, citing the work by Smith and Parker (2015), Kongsuwan (2020) concludes that, “Theory is necessary to science and science grounds legitimate and essential practice. This is true for nursing as a discipline of knowledge and a practicing profession” (p. 37).

3. Identify a theory/theorist of your choice, discuss the theory, and provide some background information about the theorist.

Born in 1924, Betty Neuman was a prominent nursing theorist and educator who is best known today for creating the Neuman Systems Model or NSM. This conceptual framework views patients holistically across physiological, psychological, sociocultural, developmental, and spiritual dimensions, emphasizing how stress can impact overall health (Verberk & Fawcett, 2017). As the research that follows shows, the NSM remains a highly influential nursing theory today – and for good reason.

The model developed by Neuman provides nursing practitioners with a comprehensive approach to nursing care based on a basic structure of variables that comprise an overall client system. These variables include normal and flexible lines of defense against stressors, with nurses serving a key role in primary, secondary, and tertiary interventions to attain optimal wellness through reducing risk factors (Montano, 2021). For instance, according to Montano (2021), “The Neuman Systems Model was developed to create a structure to depict nursing clients as complex systems, in constant energy exchange with their environments, comprised of multiple interrelated parts. It has been widely used in practice, education, research, and administration” (p. 45). Although Neuman passed away in 2012, her legacy and influence on the nursing profession lives on as explained below.

4. Explain your rationale for choosing the theory/theorist and give a brief summary of their background

One of her many biographers emphasizes that Neuman invested significant time, effort and research into developing the NSM. For instance, according to the nursing staff at Advent Health University, “Neuman spent considerable time earning her education and constructing NSM theory. In 1957, [Neuman] earned majors in public health and psychology from the University of California in Los Angeles” (What is the Neuman Systems Model?, 2017, para. 5). During the early years of her professional nursing career, Neuman developed the “first patient whole-healing theory” in the 1970s and went on to publish her influential study, “Conceptual Models for Nursing Practice” which explained her NSM theory in more detail in 1974. This study and Neuman’s model have since been updated several times (What is the Neuman Systems Model?, 2017).

5. Identify a method for Theory Evaluation and briefly explain the components of the method

Methods for nursing theory evaluation are systematic approaches used to assess the validity, relevance, and utility of nursing theories in various contexts. These methods serve as structured frameworks for critiquing and analyzing nursing theories based on various predetermined criteria such as clarity, simplicity, testability, and practicality (Reed, 2022). Nursing theory evaluation is essential because it provides the opportunity for nurses, educators, researchers, and policymakers to assess the strengths and limitations of different theories, thereby informing evidence-based practice, education, and research initiatives in the nursing field.

In addition, by evaluating nursing theories, professionals can determine their applicability to diverse clinical situations, populations, and settings, as well as their potential to guide nursing interventions, improve patient care outcomes, and advance the nursing profession as a whole (Reed, 2022). One especially useful method for evaluating nursing theories is the Criteria-Based Model for Evaluating Nursing Theories developed by Jacqueline Fawcett. In sum, Fawcett developed a set of standards to evaluate the soundness and suitability of theoretical nursing frameworks that have subsequently been widely adopted as explained below.

A key component of Fawcett’s method for nursing theory evaluation is the application of objective, nonjudgmental assessment across delineated criteria. In particular, significance refers to how thoroughly and cohesively a theory encompasses core conceptual elements of the nursing metaparadigm, including an articulated conceptual model as well as underlying philosophical assumptions. Internal consistency examines the structural integrity of the theory, analyzing if conceptual definitions, relationships and logical flow align without contradictions. Likewise, parsimony is used to “clarify the proposition and concepts of a theory without oversimplifying the phenomenon of interest” (Iduye, 2022, p. 59).

In the context of Fawcett’s theory evaluation model, testability assesses the feasibility of theoretical frameworks for empirical testing, quantifying concepts as variables and postulating propositions that lend to verification through evidence (Iduye, 2022). Finally, the pragmatic adequacy and empirical adequacy variables in Fawcett’s theory are used to gauge the nursing theory’s applicability for practical implementation to guide nursing decisions and demonstrated alignment with real-world observations respectively. In other words, my methodically scrutinizing across these areas, nurses can determine a theory’s appropriateness for adoption in practice and ongoing research (Iduye, 2022). In this regard, Iduye emphasizes that, “Fawcett’s (2005) criteria for theory evaluation imply an objective and nonjudgmental description of the theory and addresses how the theory meets specific evaluation criteria” (p. 60).

6. Provide a brief summary of the main components of Neuman’s System Model theory

As noted above, the nursing process conceptualized within the NSM involves systematic patient assessment, diagnosis, planning, implementation, and evaluation, all of which are geared towards assisting individuals in achieving or maintaining a state of equilibrium with the wide array of internal and external variables that affect health. Briefly, Neuman’s System Model theory underscores the holistic nature of nursing care, emphasizing the interconnectedness of biological, psychological, sociocultural, and environmental factors in influencing health and well-being.

7. Give specific examples of how your chosen theory can be applied in nursing practice

One of the major strengths of Neuman’s holistic view of the patient is its ability to shape comprehensive nursing assessments that gather data across physiological, emotional, sociocultural, spiritual, and developmental domains to provide nurses with fresh insights concerning on all factors impacting health and wellness that might not be available otherwise. Likewise, Neuman’s theoretical model helps nurses identify current or potential stressors such as lack of social support, financial hardship, or physical disability that may diminish normal defenses and require targeted interventions. Skilled nursing facilities could leverage the Neuman framework to design rehabilitation programs addressing the whole patient through exercise, counseling, community integration efforts and spiritual practices.
