Theory A set of related statements that describes/explains phenomena
in a systematic way.
Theory comes from the Greek word, theoria , which means a
be holding, spectacle or speculation.
Theories are always speculative in nature and are never
considered to be true or proven.
They are always subjected to further development and revisionor may even be discarded if not supported by empirical
evidence

Concept
Concepts are building blocks of a theory.
A concept is a word picture or mental idea of a phenomenon.
They are words or ideas that symbolize some aspect of reality. A concept may be very concrete such as human heart or very
abstract such as love.
Concrete concepts may be specified and defined more easily
than abstract concepts.

Construct Construct is highly abstract phenomenon or concept.
It is the term used to indicate a phenomenon that cannot be
directly observed but must be inferred by certain concrete or
less abstract indicators of the phenomenon.
Examples of construct include wellness, mental health, self
esteem and assertiveness.
Each of these concepts can be identified by the presence of
some measurable concepts

Proposition Proposition is a statement or assertion of the relationship
between concepts.
Propositional statements derived from theories or from
generalizations based on empirical data.
These statements may indicate the relationship between
concepts in several ways and may assert two events tend to
vary together.
-

Proposition . . .
Example, there is a relationship between pulse rate and
respiratory rate.
Propositional statements may also assert that one variablecauses on other variable.
Example, bacteria causes disease.

Model Model is a symbolic representation of some phenomenon or
phenomena.
It represents some aspect of reality, concrete or abstract.
It may be structural, pictorial, diagrammatic, or mathematical.
Difference between theory and model; theory focuses on
statements or explanations of the relationship between
phenomena, a model focuses on the structure or composition
of phenomena.

Contd Phenomena - It is an idea or fact or event that appears or is
perceived.
Paradigm - the network of science, philosophy and theory
accepted by a discipline or person. The prevailing paradigm directs the activities of a discipline.
Metaparadigm - the most global perspective of a discipline,
singles out the phenomena with a discipline deals in a unique
manner, i.e. person, environment, health, illness, etc.

Nursing theory
Nursing theory is the term given to the body of knowledge thatis used to support nursing practice.
In their professional education, nurses will study a range ofinterconnected subjects which can be applied to the practicesetting.
This knowledge may be derived from experiential learning,from formal sources such as nursing research or from non-nursing sources.

Nursing theory
Nursing is many things to many people. Most universally agreed upon is that Nursing is a science
involving people, environment and process fueled by a visionof transcendence in the context of healthcare.
It is interesting to note that 90% of all nursing theories have been generated in the last 25 years.
Many schools encourage students to formulate personal philosophies or mid-range theories of Nursing as part of theircurriculum.
Some might argue that this multiplicity of theory is detrimental(harmful) to the practice and undermines common vision.

Nursing theory . . .
Others would say that the nature of the young science is
sufficiently far reaching to require such tactics in order to elicit
true consensus.
Nursing theory provides the foundation of nursing knowledge
and gives direction to nursing practice.
Nursing theory should guide the development and futuredirection of nursing research.

Nursing theory . . . Barnum (1994) offers this vivid analogy to describe nursing
theory: A theory is like a map of a territory as opposed to an aerial
photograph. The map does not display the full terrain(building, roads, moving, vehicles, or grazing livestock):instead it peaks out these parts that are important for its
purpose. If its aim is to guide travelers, the map will highlightthe roads; if its purpose is to describe its terrain, it will showits mountains, plains and rivers. But no map or theory reflects
all that is contained with in a phenomenon. Such a map willdefeat its purpose; giving one a handle on the phenomenon.The handle is created by making the essential parts stand outin relief.

Importance of nursing theories used to describe, develop, disseminate, and use present
knowledge in nursing. provide a framework for nurses to systematize their nursing
actions: What to ask, what to observe, what to focus on and what to
think about. They provide a framework to develop new and validate
current knowledge. used to define commonalities of the variables in a stated field
of inquiry; guide nursing research and actions predict practice outcomes predict client response.

Classification of nursing theories
A. Depending On Function Descriptive -to identify the properties and workings of a discipline
Explanatory -to examine how properties relate and thus affect the
discipline
Predictive -to calculate relationships between properties and how
they occur
Prescriptive -to identify under which conditions relationships
occur

Classification of nursing theories
Middle range theory: is more precise and only analyses a particular situation with a limited number of variables.
Practice /prescriptive/micro theory: explores one particularsituation found in nursing.
It identifies explicit goals and details how these goals will beachieved.

Contd
1. Needs theories These theories are based around helping individuals to fulfill
their physical and mental needs.
Needs theories have been criticized for relying too much on
the medical model of health and placing the patient in an
overtly dependent position.
-
8/12/2019 Philosophy of Nursing Theory
22/98
Classification of nursing theories
2.Interaction theories As described by Peplau (1988), these theories revolve around
the relationships nurses form with patients.
Such theories have been criticized for largely ignoring the
medical model of health and not attending to basic physical
needs.
3. Outcome theories
Outcome theories portray the nurse as the changing force, who
enables individuals to adapt to or cope with ill health.
-
8/12/2019 Philosophy of Nursing Theory
23/98
Classification of nursing theories
Outcome theories have been criticized as too abstract and
difficult to implement in practice.
4. Humanistic Theories Humanistic theories developed in response to the psycho-
analytic thought that a persons destiny was determined early
in life. Humanistic theories emphasize a persons capacity for self -
actualization.
-
8/12/2019 Philosophy of Nursing Theory
24/98
Classification of nursing theories
Humanists believe that the person contains within himself the
potential for healthy & creative growth.
Carl Rogers developed a person centered model of psychotherapy that emphasizes the uniqueness of the
individual.
The major contribution that Rogers added to nursing practiceis the understandings that each client is a unique individual, so,
person-centered approach now practice in nursing.

Development of nursing theory The development of nursing theory has provided direction for
the structure of professional nursing practice, education, andresearch
The introduction of nursing theory historically begins withFlorence Nightingale
Conceptual and theoretical nursing models generateknowledge that will:
improve nursing practice guide nursing approach facilitate the organization of curricula for all levels of
nursing education

Development . . .
From nursing science, conceptual models and nursing theories
evolve.
As the profession continues to expand, its own body of
knowledge, concepts and theories continue to develop to
support nursing practice component .

Nightingale's environmental theory
It is one of Nightingale's nursing theories Incorporated the restoration of the usual health status of the
nurse's clients into the delivery of health care
Disease - reparative process
Nurses role - manipulating the environment to facilitate this
process
Her intent was to describe nursing and provide guidelines for
nursing practice and education
-
8/12/2019 Philosophy of Nursing Theory

Factors present in the patient's environment
Pure or fresh air
Pure water
Sufficient food supplies Efficient drainage
Cleanliness
Light (especially direct
sunlight)
Ventilation and warming -
Building sickness
Noise Observation of the sick
Social considerations
-
8/12/2019 Philosophy of Nursing Theory

Major concepts defined by Nightingale Patient an individual who is responsible, creative, in control
of their lives and health, and desiring good health.
Health a state of wellbeing; using ones power to the fullest.
Illness - the reaction of the nature against the conditions inwhich we have placed ourselves.
Environment is external to the person, but affecting the
health of both sick and well persons.
-
8/12/2019 Philosophy of Nursing Theory
31/98
Environmental.
The environment, one of the chief sources of infection, must
include fresh air, fresh water, efficient drainage, cleanliness,
and light.
Nursing - a service to people intended to relief pain and
suffering.
The goal of nursing is to promote the reparative process by
manipulating the environment.
-

Application Applies in all situation that nursing care is provided.
Allows clients to change/ adapt in relation to their diseased
state.
It is used by managers and leaders to influence the positionsabout the nursing care today.
-
8/12/2019 Philosophy of Nursing Theory
33/98
Application The practice of environment configuration according to
patient's health or disease condition is still applied today
E.g. in cases as patients infected with Clostridium tetani
(suffering from tetanus), who need minimal noise to calm
them and a quiet environment to prevent seizure-causing
stimulus.

Hendersons Human Needs Theory Virginia Henderson viewed nursing as an art and a discipline
separated from medicine.
She believed that The unique function of the nurse is to assist
the individual, sick or well, in the performance of thoseactivities contributing to health or its recovery (or to a peaceful
death) that he/she would perform unaided if he/she had the
necessary strength, will or knowledge. Identified 14 components of Basic Nursing Care (basic needs
of the patient) :

14 basic needs . . .
9. Avoid changes in the environment and avoid injuring others.10. Communicate with others expressing emotions, needs, fears,
or opinions.
11. Worship according to ones faith.
12. Work in such a way that there is a sense of accomplishment.
13. Play or participate in various forms of recreation.
14. Learn, discover, or satisfy the curiosity that leads to normal
development and health and use of the available health
facilities.
-
8/12/2019 Philosophy of Nursing Theory

Major concepts defined by Henderson
Patient individual; requires assistance to achieve health and
independence or a peaceful death.
Individual will achieve or maintain health if they have the
necessary strength, will or knowledge.Health is a quality of life basic to human functioning.
Health is equated with independence, while illness is
associated with a lack of independence .

Theory critique
Hendersons theory closely corresponds to Maslows hierarchyof needs
However, she omitted self- actualization from the remit of the
nurse. Henderson viewed the nurses role as that of a substitute for
the patient , helper to the patient, and a partner with the patient.
She listed 14 basic needs that nurses should assist patients with
if the patients are unable to perform them unaided.
-
8/12/2019 Philosophy of Nursing Theory
41/98
Theory critique These basic needs compose Hendersons component of
nursing care, which mainly focuses on nursing is an art.
Hendersons 14 basic needs are the basis for activities of daily
living theory. Hendersons theory is useful in nursing as the nurse can use
the fourteen basic needs as a basis for their nursing
assessment .

Orems self care deficit theory
Dorothea Orem first published her concepts of nursing insustaining in 1959, refining them in 1980 and 1985.
Originally, she designed her theory for nursing school
curricula to help students differentiate among nursing actions. She worked on three theories, self care deficits, theory of self
care and theory of nursing systems.
This theory focuses on identifying the patients self-care needs
and nursing actions designed to meet the patients needs.

Orems General Theory of Nursing
Three Interrelated Theories:
1. Theory of Self-Care = why and how people care for themselves
2. Theory of Self-Care Deficit = why people can be helped
through nursing
3. Theory of Nursing Systems = describes and explains
relationships that must be made and maintained for nursing to be produced
-

Self-Care Theory
Based on the concepts of:
Self-care
Self-care agency
Self-care requisites
Therapeutic self-care demand
-
8/12/2019 Philosophy of Nursing Theory
46/98
Self Care Theory Concepts
Self Care
The performance of
activities that individuals
initiate and perform on
their behalf to maintain
life, health, and well-
being.
-
8/12/2019 Philosophy of Nursing Theory
47/98
Self Care Theory ConceptsSelf-Care Agency
The individuals ability to perform self -care activities
Consists of TWO agents:
Self-care Agent - person who provides the self-care
Dependent Care Agent - person other than the individual
who provides the care (such as a parent)
-
8/12/2019 Philosophy of Nursing Theory
48/98
Self Care Theory Concepts
Self -Car e Requi si tes Reasons for which self-care is done; these express the intended or
desired results Consists of THREE categories:
Universal - requisites/needs that are common to all individuals(e.g. air, water, food, elimination, rest, activity, etc.)
Developmental - needs resulting from maturation or developdue to a condition or event (e.g. adjustment to new job,
puberty) Health Deviation - needs resulting from illness, injury &
disease or its treatment (e.g. learning to walk with crutchesafter a leg fracture)
-
8/12/2019 Philosophy of Nursing Theory

Self Care Theory Concepts
Therapeutic Self-Care Demand The totality of care measures necessary at specific times or
over a duration of time for meeting an individuals self -care
requisites by using appropriate methods and related sets and
actions.

Self-Care Deficit Nursing Theory
The condition that validates the existence of arequirement for nursing in an adult is the health
associated absence of the ability to maintain
continuously the amount and quality of therapeutic
self-care in sustaining life and health, in recovering
from disease or injury, or in coping with their effects.
-
8/12/2019 Philosophy of Nursing Theory
51/98
Self-Care Deficit Nursing Theory
Is the central focus of Orems grand theory of nursing
Nursing is required when adults (parent/guardian) are
incapable of or limited in their ability to provide continuous
effective self-care .
Describes and explains how people can be helped through
nursing
Nursing meets these self-care needs through five methods
of help.
-

Theory of Nursing Systems
-
8/12/2019 Philosophy of Nursing Theory
53/98
Theory of Nursing Systems This describes:
How the patients self care needs will be met by the nurse , the
patient, or both
Nursing responsibilities.
Roles of the nurse and patient
Rationales for the nurse-patient relationship
Types of actions needed to meet the patients demands Designed by the nurse
Based on the assessment of patients ability to perform self -care
activities

54/98
Three Classifications of Nursing Systems
1. Wholly Compensatory : a patients self -care agency is solimited that s/he depends on others for well-being.
a. Unable to engage in any form of action (e.g. coma ) b. Aware and who may be able to make observations or
judgments, and decisions about self-care but cannot/shouldnot perform actions requiring ambulation and manipulativemovements (e.g. patients with vertebral fractures )
a. Unable to attend to themselves and make reasonable judgments about self-care but who can be ambulatory andable to perform some self-care with guidance (e.g. severelymentally incompetent )

2. Partly Compensatory : A patient can meet some self-care
requisites but needs a nurse to help meet others; either the nurse
or the patient have the major role in the performance of self-

Major concepts defined by Orem (general) Patient - is an individual unable to continuously maintain self-
care in sustaining life and health, in recovering from disease or
injury, or in coping with their effects.
Health ability to meet self care demands that contribute tothe maintenance and promotion of structural integrity,
functioning and development.
Illness occurs when an individual is incapable ofmaintaining self-care as a result of health related limitations.

Environment Any setting in which a patient has un-meetself care needs.
Nursing A service of deliberately selected and performed
actions to assist individuals to maintain self care, including
structural integrity, functioning, and development.

Theory critique
Orems theory is useful for comprehensive assessment andanalysis of individuals.
The theory is very useful for nurses working with chronically
ill patients in the hospital or other settings.
It is also used in health maintenance and illness prevention.
The term self-care is used by so many premises which may
create confusion.
Individuals emotional needs are neglected.

Roys Adaptation Model
She focused the individual as a bio-psychosocial adaptivesystem
Described nursing as a humanistic (values others opinions and
viewpoints) discipline that places emphasis on persons coping
abilities.
According to Roy, the individual and environment are sources
of stimuli that require modification for adaptation.
-

8/12/2019 Philosophy of Nursing Theory
66/98
Major concepts defined by Roy Patient a person or family with unusual stressors or ineffective
coping mechanisms.
Health - a step and process of being and becoming adapted and
whole.
Illness - a lack of integration
Environment all conditions, circumstances, and influences
surrounding and affecting the development and behaviour of persons
or families.
Nursing promotion of patients effective coping and progress
toward adaptation.
-
8/12/2019 Philosophy of Nursing Theory
67/98
Theory critique Roys theory is useful in guiding the nurse in nursing
observation and interviewing skills to make an individualized
assessment of each person
Serves as a guide in planning and carrying out nursing careaction.
Some concepts remain ambiguous e.g. how does adaptation
takes place. Also the theory only includes assessment and interventions
and not the full nursing process.

Neumanns health care system model
Developed by Betty Neumann This is a complex system theory, with a focus on stress
reaction and stress reduction.
This comprehensive theory depicts the patient as the core of a
circle (genetics, organ strength or weakness, normal
temperature range) with several protective layers.
N h l h d l

8/12/2019 Philosophy of Nursing Theory
69/98
Neumanns health care system model The patient is continuously exposed to internal and external
stressors:
loss, change, grief, sensory deprivation, and cultural
change
which requires line of defence (nutrition, rest, hydration,
oxygen, financial circumstances, employment, and lifestyle )
and reactions (role expectations, and copping patterns).
Nursing interventions can occur before or after stressors and
at three levels of prevention: primary, secondary, and tertiary.

Major concepts defined by Neumann Patient- is an open system seeking balance and harmony,
composite of physiological, psychological, socio-cultural, and
developmental variables and viewed as a whole.
It may refer individuals, families, and communities. Health - A dynamic equilibrium of the normal line of defence.
-
8/12/2019 Philosophy of Nursing Theory
72/98
Neumanns health care system model
Illness - illness is due to reaction to stressors with lines of
resistance (immune and inflammatory response systems).
Environment - comprises internal and external stressors and
resistance factors.
Nursing reduction of stressors through prevention activities
at three levels.

Critique
Neumanns theory is applicable to all phases of nursing
process.
It can be applied across all clinical areas and is especially
useful for individuals and families.
It uses a holistic approach because each system or subsystem
cannot be isolated; rather, the influence of each system on the
whole must be considered. The three levels of prevention are useful guides for planning
interventions.
-
8/12/2019 Philosophy of Nursing Theory
74/98
Theory critique
Particularly useful to nurses working in the community setting ,
but can also be used in the hospital or clinical environment.
It specially shows how to use the nursing process in both
settings.
However, it is wellness oriented, and she uses the terms health
and wellness interchangeably as if they mean the same thing. Also, it is prevention rather than treatment oriented.

Major concepts defined by Roper, Logan and Tierney
Patient - any individual needing help to perform activities of
daily livings.
Health - can only be defined in relation to the individual and
his expectations, and in relation to his optimal level of
functioning in everyday living.
Environment - houses, factories, and offices, sports grounds
and playgrounds and rounds are all environments.
There is also the broader view of environment e.g. climate and
geographical location.

General system theory
Provides another approach for studying individuals in their
environment and is used by many disciplines.
General system theory includes content, purpose and process,
breaking down the whole and analyzing the parts.
The relationships between the parts of the whole are examined
to learn how they work together.

General system theory . . . .
Von Bertalanffy (1969 - 1976) developed general system theorywhich assumes the following:
All systems must be goal directed.
A system is more than the sum of its parts .
A system is ever-changing, and any change in one parts affects
the whole.
Bounders are implicit, and human systems are open and
dynamic.

Human needs theory
Maslows hierarchy of humans needs is any physiological or
psychological factors necessary for a healthy existence.
The most prominent theorist to focus on human needs has been
Abram Maslow (1970).
Human needs theory

8/12/2019 Philosophy of Nursing Theory
86/98
Human needs theory
It states that all humans are born with instinctive needs.
These needs grouped into 5 categories; are arranged in the
order of importance from those essential for physical survival
to those necessary to develop a persons fullest potential. provides a framework for recognizing and prioritizing basic

Human needs theory Deficiency needs must be met first.
Once these are met, seeking to satisfy growth needs drives
personal growth.
The higher needs in this hierarchy only come into focus when
the lower needs in the pyramid are satisfied.
Once an individual has moved upwards to the next level, needs
in the lower level will no longer be prioritized.

g y People grow and change throughout their lives.
Change happens daily. This changes and growth affects human kinds.
Change is continuous.
Reactions to changes are grounded in the basic human needs
for self-esteem, safety, and security.

Change theory . . .
Lewin identified three states of change: unfreezing,
movement, and refreezing.
Unfreezing is the recognition of the need for change and the
dissolution of previously held patterns of behaviour. Movement is the shift of behaviour towards a new and more
healthful pattern.
Refreezing is the long term solidification of the new pattern
of behaviour.
