CHAPTER SIXFAMILIES AS SYSTEMS
The Practice of Generalist Social Work (2nd ed.)
Key Ideas
Systems theory helps social workers to conceptualize families as highly organized systems, whose parts are dependent on one another.
These components can be used in interventions to help improve family functioning.

Component Changes
Also known as homeostasis, systems theory posits that a change in one part of the system affects other parts of the system.
All systems strive to maintain homeostasis, regardless of whether that homeostasis results in positive or negative functioning for the system.
