What defines a closed system in the context of family therapy?

1. A self-contained system with permeable boundaries

2. A system that is open to outside influences

3. A self-contained system with impermeable boundaries

4. A family unit focusing on external relationships

The correct answer is: A self-contained system with impermeable boundaries

In the context of family therapy, a closed system is defined as a self-contained system with impermeable boundaries. This means that the family operates independently from external influences and experiences, which can significantly affect how the family interacts, communicates, and resolves conflicts. In a closed system, the members may be resistant to external input, maintaining strict boundaries that prevent outside perspectives from entering their relational dynamic. This fundamentally shapes the family’s internal dynamics, creating a unique environment that can either help or hinder growth and development depending on the circumstances. By understanding this definition, it becomes clear why a self-contained system with impermeable boundaries is crucial in recognizing the nature of a closed system. The family's interactions are tightly regulated and often insular, which can lead to a lack of adaptability. This contrasts sharply with other types of systems that may be more open to influences from the outside, which typically allows for a different dynamic in terms of relationships and problem-solving. Recognizing these characteristics is essential for therapists in identifying the types of boundaries present and how they impact the family’s functioning and therapeutic work.
