Health Behavioral Model

Dorothy Johnson's belief that medicine and nursing were two distinct disciplines and that research-based knowledge was needed to study the effect of nursing care on patients led her to develop the Behavior System Model of Nursing. The theory was first introduced in 1961 and presented in its final form in 1980.

Dorothy E. Johnson was a professor at the University of California, Los Angeles (UCLA) School of Nursing for most of her nursing career. Working at a time of transition in nursing education, she made an important contribution to the way nursing is viewed and practiced. Florence Nightingale's concept of placing primary needs of the patient ahead of the disease process had a great influence on Johnson and her model of nursing.


Johnson's nursing theory states that nursing care should facilitate the maintenance of a patient's state of equilibrium. She believed that nursing was an independent profession rather than an adjunct of medicine. As an advocate of higher education for nurses, she considered nursing a science as well as an art. Her 1968 paper, One Conceptual Model of Nursing, is an early example of her thoughts.

The Behavior System Model of Nursing has major concepts, assumptions, subsystems and nursing goals as listed below.

Major Concepts

  • Medicine focuses on the biological system of the person while nursing focuses on the behavioral system.
  • The behavior of a person is directly related to his environment and the events that occur within that environment.
  • A person has an adaptive response to internal and external stimuli that affect the stability of health. These responses can be physical, emotional and/or sociological.
  • The main goal of nursing is to maintain the equilibrium of the behavioral system during a disruption of the biological system.

Assumptions about the System

  • Behaviors that make up the system are organized and interdependent and make up an integrated whole.
  • The system is constantly trying to maintain balance by adjustments to natural forces.
  • The behavioral system is essential for each individual.
  • The balance of the system is the result of successful adaptations and adjustments.

Assumptions about Structure and Function

  • The form that the behavior takes depends upon the goal that is being sought.
  • Each person has an inborn tendency to act in certain ways.
  • There are a variety of choices for action within each subset.
  • The patient's behavior provides an observable outcome.

Requirements for Subsystems

  • The system must be protected from harmful influences.
  • The system must be nurtured with suitable input from the environment.
  • Growth does not occur without stimulation.

Subsystems

  • Attachment provides a social bond with other people.
  • Dependency includes physical assistance, emotional approval and recognition.
  • Ingestive incorporates the structure and meaning of social events in which food is eaten.
  • Eliminative patterns that are socially acceptable vary from culture to culture and affect behavior.
  • Sexual beliefs affect behavior and actions.
  • Aggressive behaviors come into play when a real or perceived threat occurs.
  • Achievement behavior is one that tries to control the environment.

Nursing Goals

  • Nurses assist patients in behaviors that are in balance with social demands.
  • Nurses help patients modify behaviors to support biological necessities.
  • Nurses help patients benefit from the physician's knowledge and skill.
  • Nurses assist the patient whose behavior does not show undue trauma as a result of the illness.
While Johnson's theory has contributed much to the practice, it is not without its critics and recommendations for improvement. Critics say that the theory focuses on the ill and hospitalized patient but does not address the promotion of health and prevention of disease. They contend that the nurse's role goes further than restoring equilibrium to the patient. It also has been said that the concepts are too abstract and do not include the nursing process.

Johnson never wrote a book about her theory but did write papers and articles. Since there is little documentation concerning her ideas for developing a nursing curriculum, this may be why her theory is not more widely known. Most of her ideas were incorporated into the curriculum at UCLA, and some of her ideas have been used at Vanderbilt University, the University of Colorado and the University of Honolulu.

Johnson's most fundamental contribution to the field of nursing is the concept of viewing nursing as an autonomous profession that has a significant impact on the health of patients. Her theory is one that deserves to be studied and applied to modern nursing practice.
