What does the “Outcome evaluation” specifically measure?

Outcome evaluation specifically measures the effectiveness of an intervention in achieving its intended goals. This type of evaluation focuses on assessing the results generated by a program, determining whether the desired changes in health indicators, behaviors, or outcomes have occurred as a result of the intervention. It looks at specific metrics related to the program's objectives, such as improvements in health status, changes in knowledge and attitudes, or reductions in disease incidence.

By measuring effectiveness, outcome evaluation helps public health practitioners understand not only if an intervention works but to what degree it fulfills its objectives. This assessment is crucial for informing future public health strategies, modifications to existing programs, and justifying resource allocation.

The other choices reflect important aspects of program evaluation, but they don't align specifically with the core focus of an outcome evaluation. For instance, fidelity of implementation relates to how closely a program is delivered according to its design, participant satisfaction measures perceptions of the program, and long-term changes in health behavior assess ongoing shifts over time rather than immediate outcomes.
