behavioral system model by Dorothy Johnson
Transcript of behavioral system model by Dorothy Johnson
Youngest in a family of seven.
Obtain her B. S. N. degree from Vanderbilt University in Nashville, Tennessee, in 1942; and her M.P.H. from Harvard University in Boston in 1948.
She began publishing her ideas about nursing soon after her graduation. She worked briefly as a public health nurse and in 1944 returned to Vanderbilt as an instructor in Pediatric Nursing.
In 1949 she joined the faculty of University California, LA where she and Lulu K. Wolf Hassenplug developed the "first four year generic basic nursing program in the United States." She held a strong conviction that continuing improvement of care was the ultimate goal of nursing.
Johnson stressed the importance of research-based knowledge about the effect of nursing care on clients.
After her retirement from UCLA Dorothy Johnson moved to the Florida coast to pursue her hobby of the study of sea shells. She remained active in retirement as a speaker and advocate for nursing education. Behavior system model Definition of nursing 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”. “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”
1. Whose behavior commensurate with social demands.
2. Who is able to modify his behavior in ways that it supports biological imperatives
3. Who is able to benefit to the fullest extent during illness from the physicians knowledge and skill.
4. Whose behavior does not give evidence of unnecessary trauma as a consequence of illness Four goals of nursing are to assist the patient: Nursing’s
Metaparadigm Person Health Environment Nursing •“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. • “Health” is a purposeful adaptive response, physically mentally, emotionally, and socially to internal and external stimuli in order to maintain stability and comfort. •“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 •“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. Assumptions Assumptions about system Assumptions about structure and
function of each subsystem Each subsystem has
three functional requirements There are 4 assumptions of system:
1.First, there is “organization, interaction, interdependency and integration of the parts and elements of behaviors that go to make up the system ”
2. 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.”
3.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.
4.Last, “system balance reflects adjustments and adaptations that are successful in some way and to some degree.” •“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. 1. System must be “protected" from noxious influences with which system cannot cope”.
2. Each subsystem must be “nurtured” through the input of appropriate supplies from the environment.
3. Each subsystem must be “stimulated” for use to enhance growth and prevent stagnation. Ingestive Attachment or affiliative Sexual Dependency Aggressive Johnson’s Behavioral Subsystem “social inclusion intimacy and the formation and attachment of a strong social bond” “approval, attention or recognition and physical assistance” “the emphasis is on the meaning and structures of the social events surrounding the occasion when the food is eaten” Eliminative “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.” " both biological and social factor affect the behavior in the sexual 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 " provokes behavior that attempt to control the environment intellectual, physical, creative, mechanical and social skills achievement are some of the areas that Johnson recognizes" nursing process Assessment Planning 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:
•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. Diagnosis 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. Evaluation
•Restorative 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: Implementation
•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’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. (1) Protection from noxious influences,
(2) Provision for the nurturing environment, and
(3) stimulation for growth. Johnson’s and Characteristics of a theory
•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 Three functional requirement of each subsystem includes Any imbalance in each system results in disequilibrium .it is nursing role to assist the client to return to the state of equilibrium. DOROTHY E. JOHNSON BSN, MPH
