Which concept best captures how changes in one family member’s behavior can ripple through the entire family system?

• A. Circular causality
• B. Linear causality
• C. Static structure
• D. Random influence

Answer: (A)

In family systems thinking, behavior spreads through feedback loops where one person’s change prompts reactions from others, and those reactions circle back to influence the original person again. This circular causation means effects aren’t a simple one-way chain but a dynamic, reciprocal process that can perpetuate or amplify patterns across the whole family. A single change can set off a chain of responses that ultimately reshapes everyone involved.

Linear causality would imply a straight line from cause to effect, which misses the back-and-forth nature of family interactions. Static structure suggests fixed roles that don’t generate ripple effects, and random influence implies irregular, unpredictable changes rather than patterned interdependence. Thus circular causality best captures the interconnected, ongoing influence within the family system.
