Johnsons Behavioral System Model (JBSM) explained about an attractive, repetitive, purposeful

ways of behaving that view person as behavioral system with their subsystem. This theory developed

in 1980. This model attempts to achieve stability and equilibrium through adaptation and regulation

the subsystems. Johnson explained the Behavioral System Model into seven subsystems and connects

them into Meta paradigm of nursing. This model can apply into nursing practice through nursing

process.

The first step in nursing process is assessment phase. The Behavioral System Model consist of

seven subsystems as major concepts (Johnson in 1980 as cited in Alligood & Tomey, 2006). These

major concepts are used as component to assess the person (client). The subsystems consist of

attachement-affiliative, dependency, ingestive, eliminative, sexual, achievement, and aggressive-

protective. The first one is attachment-affiliatve that related to social involvement that uphold a well-

built social relationship. The second is dependency subsystem that can be assessed by asking and

observing situation that made client being dependent to others help. The third is ingestive that related

to wide-ranging function of the need to eat. Eliminative is including the fourth subsystem that address

reason, time, and condition people eliminate. Another subsystem is sexual subsystem as reproduction

and satisfaction. The other subsystem is achievement subsystems that try to control environment by

people capability. And the last subsystem is aggressive-protective subsystem as guard and

conservation.

The strength of the assessment phase while using JBSM is that the model guided nurse to assess

client considering the bio-psiko-socio-environment perspective. Otherwise, the component of

achievement subsystem linked client with the environment on object and situation on clients

perspective, it is not described environment as a part that can give impact to client. The element of

assessment more likely to use in clinical setting than community, community nursing care needs to

assess environment resource beside the resources of client.

After assessed the component within seven subsystems, the problems appeared through imbalance

of one or more subsystems of client. Then, those data is organized to fit the classification of diagnosis.

The diagnosis classified into four categories such as: insufficiency, discrepancy, incompatibility, and

dominance. The strength of diagnosed phase utilize JBSM is the diagnosis reflect on anticipated

disease not only the actual disease. However, the limitation of this model of diagnosis is focus on

general aspect of system in the model not specifically described the detailed problem in each

subsystem.

Intervention and implementation phase in JBSM consist of three types such as nurturance that

demonstrated direct care of nurse; protection that demonstrated the assisting, maintaining, and

expanding the coping mechanism; stimulation that demonstrated nurse as role model provided

knowledge and client needs to perform nursing care process. This model facilitated the cooperation

between nurse and client can be considered as the strength of its utilization. Nonetheless, the usage of

this model is focused on facilitate stability state when patient in disease condition, and a few

explanation that demonstrated prevention and health promotion.

The last step of nursing process is evaluation. The outcome of nursing intervention is to achieve

the stability of system. Equilibrium of system is showed by well-functioning of each subsystem after

nurse performed nursing care to overcome the problems of client or assist client to cope with the

problems. The evaluation is involved worth differences both internal and interpersonal aspect of client.

In conclusion, Johnsons Behavioral System Model (JBSM) can be utilized in nursing practice through

the nursing process. However, nurse while using this model need to add another component to provide

nursing care more holistically.
