Systems Perspective and Social Change: Lester's Case

Listing the systems around a client is not a systems perspective. What makes it one is showing how a change in one produces a change in another.

Systems interact — the verb is the assignment

The quotation the prompt uses says clients are in constant dynamic interaction with other systems, and interaction is the word that decides whether a post demonstrates the perspective or merely names it. Listing family, workplace, healthcare and community around Lester is an inventory. A systems perspective shows the couplings: his injury removes his income, which changes his standing in the family, which changes what his adult children feel able to ask of him and what he feels able to accept from them; his insurance status determines his rehabilitation, which determines his function, which determines whether returning to work is possible at all; his community's physical accessibility decides whether he can maintain the relationships that buffer the rest. Each of those is a chain, and drawing at least two of them is what the assignment is asking for. Pick the two chains you can trace furthest and follow each to its end.

Use the standard vocabulary properly, because it is precise. Micro, mezzo and macro name levels; a change at the macro level — an insurance rule, a transport policy, a disability benefit threshold — reaches Lester through the mezzo systems he belongs to rather than directly. Boundaries, feedback loops and homeostasis are the mechanisms worth naming, and homeostasis is the most useful of them here: families resist change, including improvement, because the existing arrangement has settled into something workable, which is why a rehabilitation gain sometimes produces family conflict rather than relief. Then answer the third question. The significance of the perspective for social work generally is that it relocates the problem: an individual who appears unmotivated may be responding rationally to a system that punishes progress, and a profession that could only see individuals would call that a personality and intervene in the wrong place.

Likely learning objectives

Inferred from the brief — check these against your own rubric.

  • 01
    Demonstrate interaction between systems rather than listing them.
  • 02
    Use micro, mezzo and macro levels accurately.
  • 03
    Apply homeostasis and feedback to a specific case.
  • 04
    State what the systems perspective changes about where intervention is targeted.

DISCUSSION 4 Systems Perspective and Social Change DISCUSSION 4: Systems Perspective and Social Change Zastrow and Kirst-Ashman (2016) stated, “Clients are affected by and in constant dynamic interactions with other systems, including families, groups, organizations, and communities” (p. 35-36). As a social worker, when you address the needs of an individual client, you also take into account the systems with which the client interacts. Obtaining information about these systems helps you better assess your client’s situation. These systems may provide support to the client, or they may contribute to the client’s presenting problem. For this Discussion, review “Working With People With Disabilities: The Case of Lester.”Consider the systems with which Lester Johnson, the client, interacts. Think about ways you might apply a systems perspective to his case. Also, consider the significance of the systems perspective for social work in general. DISCUSSION 4: Systems Perspective and Social Change. · Post a Discussion in which you explain how multiple systems interact to impact individuals. · Explain how you, as a social worker, might apply a systems perspective to your work with Lester Johnson. · Finally, explain how you might apply a systems perspective to social work practice. Be sure to support your posts with specific references to the resources. If you are using additional articles, be sure to provide full APA-formatted citations for your references. References

Review before submission

Common mistakes

  • Listing the systems around the client instead of showing interaction.
  • Using micro, mezzo and macro as synonyms for small, medium and large.
  • Applying the perspective to Lester without reaching the general question.
  • Omitting the mechanisms — boundaries, feedback, homeostasis — that make it a theory.

Submission checklist

  • Have you traced at least two causal chains between systems?
  • Are the three levels used correctly?
  • Is at least one systems mechanism named and applied to Lester?
  • Does the post answer the general question as well as the case one?
