In the epidemiological process, what step comes after identifying the problem?

• A. Formulate a theory (diagnosis/analysis)
• B. Gather information
• C. Formulate a plan
• D. Follow up

Answer: (A)

In epidemiology, once a health problem is identified, the next move is to formulate a working theory or diagnosis that explains why the problem is occurring. This step sets up plausible causes, risk factors, and mechanisms and guides what data to collect and which analyses to perform. Having a theory makes information gathering purposeful: you test the proposed explanations, collecting focused data to support or refute them. Only after testing and refining the theory do you move on to formulating a plan for intervention and later follow-up to evaluate outcomes. Without a guiding theory, data collection can become unfocused and less useful for understanding and addressing the problem.
