Introduction-
Dorothy E. Johnson was born August 21, 1919, in Savannah, Georgia.
-
B. S. N. from Vanderbilt University in Nashville, Tennessee, in 1942; and her M.P.H. from Harvard University in Boston in 1948.
-
From 1949 till retirement in 1978 she was an assistant professor of pediatric nursing, an associate professor of nursing, and a professor of nursing at the University of California in Los Angeles.
-
Johnson stressed the importance of research-based knowledge about the effect of nursing care on clients.
Behavior system model
-
Dorothy first proposed her model of nursing care in 1968 as
fostering of “the efficient and effective behavioral functioning in
the patient to prevent illness".
-
She also stated that nursing was “concerned with man as an
integrated whole and this is the specific knowledge of order we
require”.
-
In 1980 Johnson published her conceptualization of
“behavioral system of model for nursing”where she explains her
definitions of the behavioral system model.
Definition of nursing
She defined nursing as “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”
Four goals of nursing are to assist the patient:-
Whose behavior commensurate with social demands.
-
Who is able to modify his behavior in ways that it supports biological imperatives
-
Who is able to benefit to the fullest extent during illness from the physicians knowledge and skill.
-
Whose behavior does not give evidence of unnecessary trauma as a consequence of illness
Assumptions
There are several layers of assumptions that Johnson makes in
the development of conceptualization of the behavioral system model viz.-
Assumptions about system
-
Assumptions about structure
-
Assumptions about functions
There are 4 assumptions of system:
-
First, there is “organization, interaction, interdependency and integration of the parts and elements of behaviors that go to make up the system ”
-
A system “tends to achieve a balance among the various forces operating within and upon it', and that man strive continually to maintain a behavioral system balance and steady state by more or less automatic adjustments and adaptations to the natural forces impinging upon him.”
-
A behavioral system, which both requires and results in some degree of regularity and constancy in behavior, is essential to man that is to say, it is functionally significant in that it serves a useful purpose, both in social life and for the individual.
-
Last, “system balance reflects adjustments and adaptations that are successful in some way and to some degree.”.
Assumptions about structure and function of each subsystem
-
“from the form the behavior takes and the consequences it achieves can be inferred what “drive” has been stimulated or what “goal” is being sought”
-
Each individual has a “predisposition to act with reference to the goal, in certain ways rather than the other ways”. This predisposition is called as “set”.
-
Each subsystem has a repertoire of choices or “scope of action”
-
The fourth assumption is that it produce “observable outcome” that is the individual’s behavior.
-
System must be “protected" from noxious influences with which system cannot cope”.
-
Each subsystem must be “nurtured” through the input of appropriate supplies from the environment.
-
Each subsystem must be “stimulated” for use to enhance growth and prevent stagnation.
-
These behaviors are “orderly, purposeful and predictable and sufficiently stable and recurrent to be amenable to description and explanation”
Johnson’s Behavioral Subsystem
-
Attachment or affiliative subsystem: “social inclusion intimacy and the formation and attachment of a strong social bond.”
-
Dependency subsystem: “approval, attention or recognition and physical assistance”
-
Ingestive subsystem: “the emphasis is on the meaning and structures of the social events surrounding the occasion when the food is eaten”
-
Eliminative subsystem: “human cultures have defined different socially acceptable behaviors for excretion of waste ,but the existence of such a pattern remains different from culture to Culture.”
-
Sexual subsystem:" both biological and social factor affect the behavior in the sexual subsystem”
-
Aggressive subsystem: " it relates to the behaviors concerned with protection and self preservation Johnson views aggressive subsystem as one that generates defensive response from the individual when life or territory is being threatened”
-
Achievement subsystem: " provokes behavior that attempt to control the environment intellectual, physical, creative, mechanical and social skills achievement are some of the areas that Johnson recognizes".
Representation of Johnson's Model

-
Dependency
-
Sexuality
-
Aggression
-
Elimination
-
Ingestion
-
Achievement
The four major concepts
- “Human being” as having two major systems, the biological system and the behavioral system. It is role of the medicine to focus on biological system where as Nursling's focus is the behavioral system.
- “Society” relates to the environment on which the individual exists. According to Johnson an individual’s behavior is influenced by the events in the environment
-
“Health” is a purposeful adaptive response, physically mentally, emotionally, and socially to internal and external stimuli in order to maintain stability and comfort.
-
“Nursing” has a primary goal that is to foster equilibrium within the individual. Nursing is concerned with the organized and integrated whole, but that the major focus is on maintaining a balance in the Behavior system when illness occurs in an individual.
Nursing process
Assessment
Grubbs developed an assessment tool based on
Johnson’s seven subsystems plus a subsystem she labeled as restorative
which focused on activities of daily living. An assessment based on
behavioral model does not easily permit the nurse to gather detailed
information about the biological systems:
-
Affiliation
-
Dependency
-
Sexuality
-
Aggression
-
Elimination
-
Ingestion
-
Achievement
-
Restorative
Diagnosis tends to be general to the system
than specific to the problem. Grubb has proposed 4 categories of
nursing diagnosis derived from Johnson's behavioral system model:
-
Insufficiency
-
Discrepancy
-
Incompatibility
-
Dominance
Implementation of the nursing care related to
the diagnosis may be difficult because of lack of clients input in to
the plan. the plan will focus on nurses actions to modify clients
behavior, these plan than have a goal ,to bring about homeostasis in a
subsystem, based on nursing assessment of the individuals drive, set
behavior, repertoire, and observable behavior. The plan may include
protection, nurturance or stimulation of the identified subsystem.
Evaluation
Evaluation is based on the attainment of a goal
of balance in the identified subsystems. If the baseline data are
available for an individual, the nurse may have goal for the individual
to return to the baseline behavior. If the alterations in the behavior
that are planned do occur, the nurse should be able to observe the
return to the previous behavior patterns. Johnson's behavioral model
with the nursing process is a nurse centered activity, with the nurse
determining the clients needs and state behavior appropriate for that
need.
Johnson’s and Characteristics of a theory
-
Interrelate concepts to create a different way of viewing a phenomenon - Concepts in Johnson's theory are interrelated.
-
Theories must be logical in nature- Johnson's theory is logical in nature.
-
Theories must be simple yet generalizable - The theory is simple.
-
Theories can be bases of hypothesis that can be tested - Research studies are conducted applying Jonhson's theory.
-
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 practitioners to guide and improve their practice.
-
Theories must be consistent with other validated theories,
laws and principles but will leave unanswered questions that need to be
investigated.
Limitation
-
Johnson does not clearly interrelate her concepts of subsystems comprising the behavioral system model.
-
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 system 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 implementation.
-
The model is very individual oriented so the family of the client is only considered as an environment.
-
Johnson does not define the expected outcomes when one of
the system is affected by the nursing implementation an implicit
expectation is made that all human in all cultures will attain same
outcome –homeostasis.
-
Johnson’s behavioral system model is not flexible.
Summary
Johnson’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. The patient
is defined as behavioral system composed of 7 behavioral subsystems.
Each subsystem composed of four structural characteristics i.e. drives,
set, choices and observable behavior.
Three functional requirement of each subsystem includes
-
(1) Protection from noxious influences,
-
(2) Provision for the nurturing environment, and
-
(3) stimulation for growth.
