3. BACKGROUND OF DOROTHY JOHNSON
Dorothy Johnson Born on
21st August 1919 in Georgia USA
1942 Bsc nursing from
Master in public health from Harvard University
Boston in 1948.
Creation of her theory began in 1940’s when
she began to teach
Retired in 1978 and died in 1999
4. JOHNSON’S BEHAVIOUR SYSTEM
The BSM of nursing was first proposed in 1968
It advocates the fostering of the patient and
effective behaviouaral functioning of the patient to
The patient is defined as a behavior system
composed of seven behavioral subsystems.
In 1980 Johnson published her
conceptualization of behavioral system of model
5. DEFINITION OF NURSING
“ An external regulatory force which acts to
preserve the organization and integration of the
patients behaviors at an optimum level under
those conditions in which the behaviors
constitutes a threat to the physical or social
health ,or in which illness is found”
6. GOAL OF NURSING ACCORDING TO
To assist the patient whose behavior is proportional
to social demands
To assist the patient who is able to modify his
behavior in ways that it supports biological
To assist the patient who is able to benefit to the
fullest extent during illness from the physician
knowledge and skills
Whose behavior does not give evidence of
unnecessary trauma as a-consequence of illness
7. THE JOHNSONS MODEL
Nurse creates a balance between client and
Protection from noxious stimuli that threaten the
survival of the behavioral system.
Nurturance ,which provides adequate input to
Stimulation to continue growth of the behavior.
8. ASSUMPTION OF BEHAVIOR SYSTEM
First assumption states that there is organization
interaction, interdependency and integration of
the parts and elements of the behaviors that go to
makeup the system.
A system tends to achieve a balance among the
various forces operates within and upon it , and
that man strives continually to maintain a
behavior system balance and steady state by or
less automatic adjustment and adoptions to the
natural forces impinging upon him.
A behavioral system, which both require and
results in some degree of regularity and
constancy in behavior is essential to man that is
to say, it is functionally significant that it serves
useful purpose, both in social life and for the
The final assumption states system balance
reflects adjustments and adoptions that are
successful in some way and to some degree.
10. JOHNSONS BEHAVIORAL SUB-
ATTACHMENT OR AFFILLIATIVE SUBSYTEM:
1) Social inclusion intimacy and the formation
and attachment of a strong social bond.
2) It provides survival and security.
1) Approval ‘attention or recognition and
2) Promote helping behavior calls for nurturing
3) Developmentally dependency behavior evolves
from almost total dependence on others to
greater degree of dependence on self.
The emphasis is on the meaning and structures of the social
events surroundings the occasion when the food is eaten.
Should not seen as input and output mechanism of the system it
has to do with ( when, how, what, how much and under what
condition we eat)
It serves the board function of appetite satisfaction .which
associate with psychological, social and biological consideration.
Human cultures have different social acceptable behaviors for
excretion waste but the existence of such a pattern remains
different from cultures to cultures.
It means when, how and under which condition we eliminate.
As ingestion system social ,psychological
Aspect influencing this subsystem.
Both biological and social factor affect the
behavior in the sexual subsystem.
It relates to the behavior concerned with the
protection and self preservation Johnson views
aggressive subsystem as one that generates
defensive response from the individual when life
or territory is being threatened
13. ACHIEVEMENT SUBSYTEM:
Provokes behavior that attempt to control
the environment intellectual, physical, creative,
mechanical and social skill achievement are
some of the areas that Johnson recognizes
14. NURSING PROCESS :-
In the assessment phase of the nursing process,
questions related to specific subsystem are
Affiliation or attachment
Insufficiency: particular system not functioning
Discrepancy: a behavior that does not meet the
intended goal ( lack of balance)
PLANNING AND IMPLEMENTATION :.
The plan will focus on nurses actions to modify
clients behavior, these plan then have a goal, to
bring about homeostasis in a subsystem, based
on nursing assessment of the individuals drive,
The plan may include protection, nurturance or
stimulation of the identified subsystem.
18. EXAMPLE :-
A 67 year old man is admitted to the hospital for
diagnostic test after CVA, he has been marriage
and father of two adult children who lives in same
city ,he came with right side weakness
,expressive aphasia and slurred speech and
1) attachment: ( family, friends)
2) Dependency ( on other physically, financially)
3) Ingestive :( decrease appetite ,difficulty
4) Elimination: ( walk to bathroom)
5) aggressive –protective:( worry of travel family
6) achievement: ( relearn walk ,talk and ADLs)
Planning and nursing intervention:
External regulatory forces that should protect
stimulated and nurture the behavior system.
Explanation and teaching the patient family and
Balance and equilibrium.
22. CHARACTERISTICS OF THE
Interrelate concepts to create a different way of
viewing a phenomenon.
Theories must be logical in nature.
Theories must be simple yet generalizable.
Theories can be the bases of hypothesis that can
Theories contribute to and assist in increasing the
body of knowledge within the discipline through
the research implemented to validate them.
Theories can be utilized by practioners to guide
and improve their practice.
24. LIMITATIONS :-
Johnson does not clearly interrelate her concepts
of subsystem .
The definition of concept is so abstract that they
are difficult to use.
It is difficult to test Johnson’s model by
development of hypothesis.
The focus on the behavioral subsystem makes it
difficult for nurses to work with physically impaired
individual to use this theory.
The model is very individual oriented so the
nurses working with the group have difficulty in its
Johnson’s behavioral system model is not
The patient is as behavioral system composed of 7
behavioral subsystems. Each subsystem composed of four
structural characteristics i.e. drives set, choice and
observable behavior. Today we have discussed regarding
the background, introduction definition of nursing
assumption, subsystem, nursing process, characteristics
and limitation of behavioral system model.
Jonson’s behavioral system model is a model of
nursing care that advocates the fostering of
efficient and effective behavioral functioning in the
patient to prevent illness. I hope u understood my
presentation and use this knowledge in clinical
