The stated goal of a(n) ______ evaluation might be "to determine whether the nutrition and smoking messages delivered through the intervention resulted in a behavior change in the target population."

The focus of an outcome evaluation is specifically on measuring the results of an intervention in terms of changes in the target population's behavior or health status. In this context, the goal is to assess whether the nutritional and smoking messages have successfully led to a behavior change, which is a clear indication of evaluating the outcomes of an intervention.

Outcome evaluations look at the end results of a program and determine if the desired changes have occurred as a result of the intervention. This includes assessing various metrics such as behavioral changes, health improvements, or other measurable effects that can be directly linked to the program.

Process evaluations, by contrast, typically focus on the implementation of the program and whether it was delivered as intended, while impact evaluations assess the intermediate effects and changes that may lead to longer-term outcomes. Structure evaluations look at the resources and systems in place to support the program. Thus, the phrasing of the goal in the question aligns specifically with the aims of an outcome evaluation.
