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,

Health Beliefs Model
Rosenstock (1966, 1990) - = "why some people change their health behaviors
while others do not."
Three components:
1. An evaluation of one's vulnerability to a condition and the seriousness of
that condition
2. An evaluation of how effective the health maintenance behavior might be
3. The presence of a trigger event that precipitates the health maintenance behavior
Self-Efficacy Concept
Bandura (1997) - 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
