Could anyone provide examples illustrating how to apply the social system theory to social work?

You are welcome.

Many thanks!

When working with a child who presents with behavioral problems at school, a social worker may fully assess the child as a system, examining the physical, biological, and physiological subsystems of the child as well as the systems that interact with the child, such as family, school, and community. After a full assessment, the social worker discovers that the parents are in the middle of a divorce and a custody battle over the child, and many mornings before the child goes to school he witnesses an argument between his parents. The social worker then decides to focus the intervention on the parents and attempts to change their patterns of interaction versus focusing on the child. Thus, a full systems assessment has enabled the social worker to determine the best system in which to intervene.
