Overview: Theoretical Foundations in Nursing By giving nurses a sense of identity, nursing theory can help patients, managers and other healthcare professionals to recognize the unique contribution that nurses make to the healthcare service (Draper 1990). Providing a definition of nursing theory also helps nurses to understand their purpose and role in the healthcare setting. 1. Definition of Terms Theory Concept Principle Nursing theory Philosophy Conceptual models Science Knowledge Phenomenon Nursing Nursing paradigms Paradigm Hypothesis Research A coherent statement or set of statements that attempts to explain observed phenomena. An explanation for some phenomena that is based on observation, experimentation, and reasoning. A comprehensive explanation of a given set of data that has been repeatedly confirmed by observation and experimentation and has gained general acceptance within the scientific community but has not been yet decisively proven. Quote: A set of concepts, definitions, relationships, and assumptions that project a systematic view of a phenomena It may consist of one or more relatively specific and concrete concepts and propositions that purport to account for, or organize some phenomenon (Barnum, 1988) Quote: Theory A set of statements that tentatively describe, explain, or predict relationships among concepts that have been systematically selected and organized as an abstract representation of some phenomenon (Power and Knapp, 1995). These systematic organized perspectives serve as guides for nursing action in administration, education, research, and practice. A well-substantiated explanation of some aspect of the natural world; an organized system of accepted knowledge that applies in a variety of situations/hypotheses. An Example of “Theory” Quote: An expectation of what should happen, barring unforeseen circumstances. Parker (2001) A theory is an organized, coherent set of concepts and their relationship to each other that offers descriptions, explanations and predictions about phenomena. Kozier (2008) is a supposition or system of ideas that is proposed to explain given phenomenon. “A herd of buffalo can only move as fast as the slowest buffalo. And when the herd is hunted, it is the slowest and weakest ones at the back that are killed first. This natural selection is good for the herd as a whole, because the general speed and health of the whole group keeps improving by the regular killing of the weakest members. In much the same way, the human brain can only operate as fast as the slowest brain cells. Excessive intake of alcohol, as we all know, kills brain cells, but naturally it attacks the slowest and weakest brain cells first. In this way, regular consumption of beer eliminates the weaker brain cells, making the brain a faster and more efficient machine. That’s why you always feel smarter after a few beers.” Quote: Concept A mental idea of a phenomenon. A comprehensive idea or generalization. An idea that brings diverse elements into a basic relationship. A unit of knowledge abstracted from a set of characteristics attributed to a class of objects, relations or entities. A unit of thought. A general idea formed in the mind. Something understood or retained in the mind, from experience, reasoning, and/or imagination; a generalization or abstraction of a particular set of instances or occurrences. Examples: person, health, environment, nursing Principle A basic generalization that is accepted as true and that can be used as a basis for reasoning or conduct. Nursing Theory A body of knowledge that describes or explains nursing and is used to support nursing practice. An organized and systematic articulation of a set of statements related to questions in the discipline of nursing. Is a set of concepts, definitions, relationships and assumptions or propositions derived from nursing models or from other disciplines and project a purposive systematic view of phenomena by designing specific interrelationships among concepts for the purposes of describing, explaining, predicting and/or prescribing. Philosophy The most basic beliefs, concepts, and attitudes of an individual or group An analysis of the grounds of and concepts expressing fundamental beliefs Is the next knowledge level after metaparadigm. It specifies the definition of metaparadigm concepts. A search for a general understanding of values and reality by chiefly speculative rather than observational means Conceptual frameworks/models A set of interrelated concepts that symbolically represents and conveys a mental image of a phenomenon. Conceptual models of nursing identify concepts and describe their relationships to the phenomena of central concern to the discipline: person, environment, health and nursing (Power and Knapp, 1995). A set of concepts and the propositions that integrate them into a meaningful configuration (Marriner-Tomey and Alligood, 1998) Composed of concepts or constructs that describe ideas about individuals, groups, situation and events of particular interest or discipline (e.g. Nursing) Hypothesis Quote: Research Research comprises "creative and systematic work undertaken to increase the stock of knowledge, including knowledge of humans, culture and society, and the use of this stock of knowledge to devise new applications." Science The organized body of knowledge gained through research. Knowledge Information, skills and expertise acquired by a person through formal/informal learning. Phenomenon A sets of empirical data or experiences that can be physically observed or tangible such as crying or grimacing when in pain. Importance of Nursing Theory It helps to distinguish what should form the basis of practice by explicitly describing nursing. This can be seen as an attempt by the nursing profession to maintain its professional boundaries. Nursing theory aims to describe, predict and explain the phenomenon of nursing (Chinn and Jacobs 1978). It provides the foundations of nursing practice, help to generate further knowledge and indicate in which direction nursing should develop in the future (Brown 1964). Theory is important because it helps us to decide what we know and what we need to know (Parsons1949). 2. Characteristics of a Theory Nursing Nursing encompasses autonomous and collaborative care of individuals of all ages, families, groups and communities, sick or well and in all settings. It includes the promotion of health, the prevention of illness, and the care of ill, disabled and dying people. (WHO) Paradigm • In science and philosophy, a paradigm is a distinct set of concepts or thought patterns, including theories, research methods, postulates, and standards for what constitutes legitimate contributions to a field. 1. Systematic, logical and coherent (orderly reasoning, no contradictions) 2. Creative structuring of ideas mental images of one’s experiences and create different ways of looking at a particular event or object. 3. Tentative in nature ( change over time or evolving but some remain valid despite passage of time) 4. Interrelate concepts in such a way as to create a different way of looking at a particular phenomenon. 5. Are logical in nature. 6. Are generalizable. 7. Are the bases for hypotheses that can be tested. 8. Increase the general body of knowledge within the discipline through the research implemented to validate them. 9. Are used by the practitioners to guide and improve their practice. 10. Are consistent with other validated theories, laws, and Principles but will leave open unanswered questions that need to be investigated. 3. Components of theory Concepts Definitions Assumptions/Proposition Phenomenon Phenomenon A phenomenon is an aspect of reality that can be consciously senses or experienced. (Meleis, 1997). Nursing theories focus on the phenomena of nursing and nursing care. Examples of phenomena in nursing include caring, self-care and client responses to stress. Why on earth do we study nursing theory? Concepts A theory is composed of interrelated concepts. Concepts help to describe or label phenomena. Everyday practice enriches theory Both practice and theory are guided by values and beliefs Theory helps to reframe our thinking about nursing Theory guides use of ideas and techniques Theory can close the gap between theory and research To envision potentialities (Gordon, Parker, & Jester, 2001) Take note: Definitions The definition within the description of a theory convey the general meaning of the concepts in a manner that fits the theory. These definitions also describe the activity necessary to measure the constructs, relationships, or variables within a theory. (Chinn and Kramer 2004) Assumptions Are statements that describe concepts or connect two concepts that are factual. Assumptions are the “taken for granted” statements that determine the nature of the concepts, definitions, purpose, relationships and structure of the theory. “The major reason for the development and study of nursing theory is to improve nursing practice and, therefore, the health and quality of life of those we serve.” 4. Purposes of Nursing Theory In Relation To: Education – nursing theory was used primarily to establish the profession’s place in the university. – provide a general focus for curriculum design. – guide curricular decision making. • • Research – nursing research identifies the philosophical assumptions or theoretical frameworks from which it proceeds. – offer a framework for generating knowledge and new ideas. – assist in discovering knowledge gaps in specific field of study. – offer a systematic approach to identify questions for study, select variables, interpret findings and validate nursing interventions. Practice – the primary contribution of nursing theory when employed in a clinical setting is the facilitation of reflection, questioning, and thinking about what nurses do. – assist nurses to describe, explain, and predict everyday experiences. defining its own independent functions. 5. Nursing paradigms – – – – Are patterns or models used to show a clear relationship among the existing theoretical works in nursing. Person Health Environment Uses of Theory serve to guide assessment, intervention, and evaluation of nursing care. provide a rationale for collecting reliable and valid data about the health status of clients, which are essential for effective decision making and implementation. help to establish criteria to measure the quality of nursing care. help build a common nursing terminology to use in communicating with other health professionals. Ideas are developed and words defined. enhance autonomy (independence and self-governance) of nursing by Nursing has a model or paradigm that explains the linkages of science, philosophy, and theory that is accepted and applied by the discipline. The elements of nursing paradigm direct the activity of the nursing profession, including knowledge development, philosophy, theory, educational experience, research, practice and literature identified with the profession (Alligood and Marriner-Tomey, 2002). Nursing – Theory guides and improve nursing practice. Theory provides goal for nursing care and with goals, nursing practice is rendered more effective and efficient. Theories help to focus the goals, making nurses more confident about the practice. Theory guides research It validates and modifies the theory. Theory contributes to the development of the disciplines body of knowledge. Theory enhances communication. Types of Nursing Theory Meta-theory - the theory of theory. Identifies specific phenomena through abstract concepts. Grand theories – broad and complex Middle-range theories- address specific phenomena and reflect practice Practice theory - explores one particular situation found in nursing. It identifies explicit goals and details how these goals will be achieved. Descriptive theories – first level of theory development Prescriptive theories – address nursing interventions and predict their consequences Grand Nursing Theory These theories have the broadest scope and present general concepts and propositions. Theories at this level may both reflect and provide insights useful for practice but are not designed for empirical testing. Grand theories consist of conceptual frameworks defining broad perspectives for practice and ways of looking at nursing phenomena based on the perspectives. Mid-Range Nursing Theories These theories are narrower in scope than grand nursing theories and offer an effective bridge between grand nursing theories and nursing practice. They present concepts and propositions at a lower level of abstraction and hold great promise for increasing theory-based research and nursing practice strategies. Nursing Practice Theories Nursing practice theories have the most limited scope and level of abstraction and are developed for use within a specific range of nursing situations. Nursing practice theories provide frameworks for nursing interventions, and predict outcomes and the impact of nursing practice. 6. Four ways of knowing Empirical Ethical Aesthetics Personal
