Homeostasis refers to a system’s natural tendency to maintain stability and resist change, even when the pattern is unhealthy. In family systems, behaviors (including symptoms) often serve a function that keeps the system balanced. When one part of the system tries to change, other members may (consciously or unconsciously) respond in ways that pull the system back to its usual pattern. This is why progress can feel “stuck” or why symptoms may reappear—because the system is trying to restore its familiar equilibrium.
Key Points to Memorize
Systems prefer stability over change
Symptoms often have a purpose (maintain balance)
Change in one member → reaction from others
Dysfunction can still feel “normal” to the system
Resistance = system trying to return to homeostasis
Exam Clues
“Every time things improve, the problem returns”
“One member improves → another worsens”
“Behavior distracts from deeper issue (e.g., marital conflict)”
Quick Example
Child acts out → parents focus on child → avoid marital conflict
Symptom = maintains homeostasis
