Which approach should be avoided when measuring outcomes in a public health campaign targeting diverse groups?

• A. Define outcomes per group
• B. Track reach and health outcomes
• C. Use a single aggregate metric for all groups
• D. Evaluate equity in access to information

Answer: (C)

Measuring outcomes across diverse groups requires looking at how each group experiences the campaign, not just the overall average. When you break data down by group, you can see whether messages reached everyone, whether people understood them, and whether the desired health actions occurred within each community. Using a single aggregate metric for all groups hides important differences—the overall number might look better, but some groups could be lagging or facing barriers that the average masks. That makes it hard to know where to improve or how to allocate resources to ensure fairness. So the strongest approach is to define outcomes for each group, track both reach and health outcomes, and evaluate equity in access to information. This way you can compare across groups, identify where gaps exist, and adjust messaging, channels, or materials to reach everyone effectively. For example, a campaign about vaccination may show overall gains, but disaggregated data might reveal that certain language groups aren’t benefiting, guiding targeted outreach to close that gap.
