Which statement about the causal web is accurate?

• A. It links indirect and direct causes, including proximal and distal factors.
• B. It replaces the component-cause model.
• C. It focuses only on distal macro determinants.
• D. It negates the role of direct causes.

Answer: (A)

A causal web is a way of showing that disease results from many interacting causes across different levels, not from a single factor. It explicitly links indirect and direct causes, bringing together proximal factors that act near the person (like behaviors or exposures) with distal factors that sit farther upstream (like socioeconomic conditions or environmental context). This perspective highlights how distal determinants shape proximal ones, creating pathways that can converge, diverge, or feed back into one another to produce an outcome.

This framing matters because it captures the complexity of real-world causation: multiple factors interact in networks, and changing one part of the web can influence others along several routes. It does not replace the component-cause model; instead, it broadens it by illustrating how several component causes come together in a network to produce disease. It also doesn’t imply that only distal determinants matter or that direct causes aren’t important—both proximal and distal, direct and indirect causes are integral parts of the web. For example, socioeconomic context can shape diet and stress, which in turn affect biological risk factors and disease.
