Introduction To Nursing Theories INTRODUCTION
■ Nursing theory is the term given to the body of knowledge that is used to support nursing practice.
■ Nursing theory is a framework designed to organize knowledge and explain phenomena in nursing, at a more concrete and specific level.
■ A nursing theory 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 inter-relationships among concepts for the purposes of describing, explaining, predicting, and /or prescribing.
■ Each discipline has a unique focus for knowledge development that directs its inquiry and distinguishes it from other fields of study.(Smith & Liehr, 2008).
■ Theory-guided, evidence-based practice is the hallmark of any professional discipline.
■ Nursing is a professional discipline (Donaldson & Crowley, 1978).
■ Almost 90% of all Nursing theories are generated in the last 20 years.
■ Nursing models are conceptual models, constructed of theories and concepts
■ A paradigm is a model that explains the linkages of science, philosophy, and theory accepted and applied by the discipline.
METAPARADIGMS IN NURSING
Person
■ Recipient of care, including physical, spiritual, psychological, and sociocultural components.
■ Individual, family, or community
Environment
■ All internal and external conditions, circumstances, and influences affecting the person
Health
■ Degree of wellness or illness experienced by the person
Nursing
■ Actions, characteristics and attributes of a person giving care.
COMPONENTS OF A THEORY DEFINITIONS
Theory
■ a set of related statements that describes or explains phenomena in a systematic way.
■ the doctrine or the principles underlying an art as distinguished from the practice of that particular art.
■ a formulated hypothesis or, loosely speaking, any hypothesis or opinion not based upon actual knowledge.
■ a provisional statement or set of explanatory propositions that purports to account for or characterize some phenomenon.
Concept
■ a mental idea of a phenomenon
■ Concepts are the building blocks (the primary elements) of a theory.
Construct
■ a phenomena that cannot be observed and must be inferred
■ Constructs are concepts developed or adopted for use in a particular theory. The key concepts of a given theory are its constructs.
Proposition
■ a statement of relationship between concepts
Conceptual model
■ made up of concepts and propositions
■ They represent ways of thinking about a problem or ways of representing how complex things work the way that they do.
■ Different Frameworks will emphasize different variables and outcomes and their interrelatedness.( Bordage, 2009)
■ Models may draw on a number of theories to help understand a particular problem in a certain setting or context. They are not always as specified as theory.
Variables
■ Variables are the operational forms of constructs. They define the way a construct is to be measured in a specific situation.
■ Match variables to constructs when identifying what needs to be assessed during evaluation of a theory-driven program.
Middle range theory
■ a testable theory that contains a limited number of variables, and is limited in scope as well, yet is of sufficient generality to be useful with a variety of clinical research questions.
| NURSING PHILOSOPHIES | |
| Theory | Key Points |
| Florence Nightingale’s Legacy of caring | ■ Focuses on nursing and the patient environment relationship. |
| Ernestine Wiedenbach: The helping art of clinical nursing | ■ Helping process meets needs through the art of individualizing care.■ Nurses should identify patients ‘need-for –help’ by:■ Observation■ Understanding client behavior |
| ■ Identifying cause of discomfort■ Determining if clients can resolve problems or have a need for help | |
| Virginia Henderson’s Definition of Nursing | ■ Patients require help towards achieving independence.■ Derived a definition of nursing■ Identified 14 basic human needs on which nursing care is based. |
| Faye G.Abedellah’s Typology of twenty one Nursing problems | ■ Patient’s problems determine nursing care |
| Lydia E. Hall :Care, Cure, Core model | ■ Nursing care is a person directed towards self love. |
| Jean Watson’s Philosophy and Science of caring | ■ Caring is a universal, social phenomenon that is only effective when practiced interpersonallyconsidering humanistic aspects and caring.■ Caring is central to the essence of nursing. |
| Patricia Benner’s Novice to Expert | ■ Described systematically five stages of skill acquisition in nursingpractice – novice, advanced beginner, competent, proficient and expert. |
| CONCEPTUAL MODELS AND GRAND THEORIES | |
| Dorothea E. Orem’s Self care deficit theory in nursing | ■ Self–care maintains wholeness.■ Three Theories:■ Theory of Self-Care■ Theory of Self-Care Deficit■ Theory of Nursing Systems■ Nursing Care:■ Wholly compensatory (doing for the patient)■ Partly compensatory (helping the patient do for himself or herself)■ Supportive- educative (Helping patient to learn self |
| care and emphasizing on the importance of nurses’ role | |
| Myra Estrin Levine’s: The conservation model | ■ Proposed that the nurses use the principles of conservation of:■ Client Energy■ Personal integrity■ Structural integrity■ Social integrity■ A conceptual model with three nursing theories –■ Conservation■ Redundancy■ Therapeutic intention |
| Martha E.Rogers: Science of unitary human beings | ■ Person and environment are energy fields that evolve negentropically■ Nursing is a basic scientific discipline■ Nursing is using knowledge for human betterment.■ The unique focus of nursing is on the unitary or irreducible human |
| being and the environment (both are energy fields) rather than health and illness | |
| Dorothy E.Johnson’s Behavioural system model | ■ Individuals maintain stability and balance through adjustments and adaptation to the forces thatimpinge on them.■ Individual as a behavioral system is composed of seven subsystems: the subsystems of attachment, or the affiliative, dependency, achievement, aggressive, ingestive-eliminative and sexual.■ Disturbances in these causes nursing problems. |
| Sister Callista: Roy‘s Adaptation model | ■ Stimuli disrupt an adaptive system■ The individual is a biopsychosocial adaptive system within anenvironment. |
| ■ The individual and the environment provide three classes of stimuli-the focal, residual and contextual.■ Through two adaptive mechanisms, regulator and cognator, an individual demonstrates adaptive responses or ineffective responses requiringnursing interventions | |
| Betty Neuman’s : Health care systems model | ■ Neuman’s model includes intrapersonal, interpersonal and extrapersonal stressors.■ Nursing is concerned with the whole person.■ Nursing actions (Primary,Secondary, and Tertiary levels of prevention) focuses on the variables affecting the client’s response tostressors. |
| Imogene King’s Goal attainment theory | ■ Transactions provide a frame of reference toward goal setting.■ Major concepts (interaction, perception, communication,transaction, role, stress, growth and development)■ Perceptions, Judgments and actions of the patient and the nurse lead to reaction, interaction, and transaction (process of nursing). |
| Nancy Roper, WW.Logan andA.J.Tierney A model for nursing based on a model of living | ■ Individuality in living.■ A conceptual model of nursing from which theory of goal attainment is derived.■ Living is an amalgam of activities of living (ALs).■ Most individuals experience significant life events which can affect ALs causing actual and potential problems. |
| ■ This affects dependence –independence continuum which is bi-directional.■ Nursing helps to maintain the individuality of a person bypreventing potential problems, solving actual problems and helping to cope. | |
| Hildegard E. Peplau: Psychodynamic Nursing Theory | ■ Interpersonal process is a maturing force for personality.■ Stressed the importance of nurses’ ability to understand their own behavior to help others identifyperceived difficulties.■ The four phases of nurse-patient relationships are:■ 1. Orientation■ 2. Identification■ 3. Exploitations■ 4. Resolution■ The six nursing roles are: |
| ■ 1. Stranger■ 2. Resource person■ 3. Teacher■ 4. Leader■ 5. Surrogate■ 6. Counselor■ Interpersonal process alleviates distress. | |
| Ida Jean Orlando’s Nursing Process Theory | ■ Nurses must stay connected to patients and assure that patients get what they need, focused on patient’s verbal and non verbal expressions of need and nurse’s reactions to patient’s behavior to alleviatedistress.■ Elements of nursing situation:■ Patient■ Nurse reactions■ Nursing actions |
| Joyce Travelbee’s Human To Human Relationship Model | ■ Therapeutic human relationships.■ Nursing is accomplished through human to human relationships that began with the original encounter and then progressed through stages of emerging identities. |
| Kathryn E. Barnard’s Parent Child Interaction Model | ■ Growth and development of children and mother–infant relationships■ Individual characteristics of eachmember influence the parent–infant system and adaptive behavior modifies those characteristics tomeet the needs of the system. |
| Ramona T.Mercer :Maternal Role Attainment | ■ A complex theory to explain the factors impacting the development of maternal roles over time. |
| Katharine Kolcaba’s Theory of comfort | ■ Comfort is a desirable holistic outcome of care.■ Health care needs are needs (physical, psycho spiritual, social and environmental needs) forcomfort, arising from stressful health care situations that cannot be met by recipients’ traditional support system.■ Comfort measures include those nursing interventions designed toaddress the specific comfort needs. |
| Madeleine Leininger’s Transcultural nursing, culture-care theory | ■ Caring is universal and varies transculturally.■ Major concepts include care, caring, culture, cultural values and cultural variations■ Caring serves to ameliorate or improve human conditions and life base. |
| ■ Care is the essence and the dominant, distinctive and unifying feature of nursing | |
| Rosemarie Rizzo Parse’s :Theory of human becoming | ■ Indivisible beings and the environment co-create health.■ A theory of nursing derived from Roger’s conceptual model.■ Clients are open, mutual and in constant interaction with theenvironment.■ The nurse assists the client in interaction with the environment and co creating health |
| Nola J.Pender’s :The Health promotion; model | ■ Promoting optimum health supersedes disease prevention.■ Identifies cognitive, perceptual factors in clients which are modified by demographic and biological characteristics,interpersonal influences, situational |
| and behavioral factors that helppredict in health promoting behavior |
CONCLUSION
■ The conceptual and theoretical nursing models help to provide knowledge to improve practice, guide research and curriculum and identify the goals of nursing practice.
■ Nursing knowledge is the inclusive total of the philosophies, theories, research, and practice wisdom of the discipline.As a professional discipline this knowledge is important for guiding practice.(Smith & Liehr, 2008).
