General Systems Theory- Ludwig von Bertalanffy (1936)
A common framework for studying several similar disciplines would allow scientists and scholars to
organize and communicate findings, making it easier to build on the work of others.
Components of Systems
-Input: material that enters a system
-Throughput: processes a system uses to convert material
-Output: end result or product of the system
-Evaluation: measures the success or failure of the output
-Feedback: information given back into the system to determine whether the purpose or end result of
the system has been achieved
Hospital as a System
The success of the hospital depends on the functioning of many subsystems
First: The whole is different from and greater than the sum of its parts (its subsystems).
Second: Synergy occurs when all the various subsystems work together to create a result that is not
independently achievable.
Supra-system
The larger environment outside the system
An OPEN system
promotes the exchange of matter, energy, and information with other systems and the environment.
A CLOSED system
does not interact with other systems or with the surrounding environment
Maslow's Hierarchy of Needs
1) Physiologic needs - food, oxygen, rest, activity, shelter, and sexual expression
2) Physical and psychological safety and security - reasonably predictable environment with which

3) Love and belonging - close intimate relations, social relations, a place in the social structure

Self-efficacy is the belief in oneself as having the ability to modify behavior
Four components for effective lifestyle change:
1) Information
2) Skill development
3) Skill enhancement through guided practice and feedback
4) Creating social supports for change
Also described a type of socialization, modeling, which is useful when learning any new behavior
(1977).
Locus of control:
People tend to be influenced by either internal or external view of control.
-Health is internally controlled. Belief that health is controlled by what they themselves do.
OR
-Health is externally controlled. Belief that health is determined by outside factors.
Holistic nursing care:

3) Nursing involves collaborating with patients and their families
4) Nursing is integrally involved with people
5) Nursing care is provided regardless of diagnosis, individual differences, age, beliefs, gender, sexual

6) Nurses require advanced knowledge and skills
7) Nursing requires concern, compassion, respect, and warmth, as well as comprehensive,
individualized planning of care, to facilitate patients' growth toward wellness.
