What is the difference between a theory and a model in social work?

• A. A theory explains why phenomena occur; a model provides a structured approach.
• B. A theory explains why phenomena occur; a model provides a structured approach or framework for practice or evaluation.
• C. They are the same.
• D. A model is always superior to a theory.

Answer: (B)

The main idea is understanding what theory does versus what a model provides in social work. A theory explains why phenomena occur and how factors are related, helping us understand patterns, predict outcomes, and generalize across situations. A model, on the other hand, is a structured approach or framework we use in practice or evaluation—it's the step-by-step blueprint that guides how we assess, intervene, and measure progress with clients or programs. In social work, you might use a theory to explain why a family’s stress affects child well-being, identifying the mechanisms at play. Then you’d apply a model to translate that understanding into concrete actions—defining problems, planning steps, implementing services, and evaluating results. The model is the practical toolset, while the theory provides the explanatory foundation behind it. That clarifies why the option stating that a theory explains why phenomena occur and a model provides a structured approach or framework for practice or evaluation is correct. The other ideas—to say they’re the same or that a model is always superior—don’t fit, because theories and models serve different purposes: one explains, the other guides concrete work.
