What does effectiveness refer to in public health programs?

• A. The cost of implementing a program.
• B. The number of participants in a program.
• C. The degree to which objectives are achieved, leading to improvement in health outcomes.
• D. The time required to implement a program.

Answer: (C)

Effectiveness is about the actual impact of a public health program on health outcomes in real-world settings. It asks to what extent the program achieves its stated objectives and whether those achievements translate into meaningful health improvements for the target population, such as lower disease rates or better health indicators.

In other words, it’s not just about delivering the program or how many people are reached or how much it costs. Those factors relate to feasibility, reach, and resources, but effectiveness focuses on the resulting health impact.
