This study describes an approach to the analysis of data that is designed to isolate program effects for evaluations and applies that approach to a program in Zambia designed to disseminate AIDS information. Evidence is considered that a radio drama broadcast for nine months had an impact on knowledge and behavior related to AIDS among Bemba speakers in northern Zambia. Using results from large sample surveys (1,600 men and women), conducted before and after the drama was broadcast, the analyses compare changes in knowledge and behavior in those most likely and least likely to have listened to the broadcast. While the population as a whole had improved its knowledge substantially, and some people reported having reduced risky behavior, attributing these changes to the program itself was not possible.
本研究描述了一种数据分析方法，该方法旨在为评估分离项目效果，并将此方法应用于赞比亚一个旨在传播艾滋病信息的项目。有证据表明，一部为期九个月的广播剧对赞比亚北部讲本巴语的人群中与艾滋病相关的知识和行为产生了影响。利用在广播剧播出前后进行的大规模抽样调查（1600名男性和女性）的结果，分析比较了最有可能和最不可能收听广播剧的人群在知识和行为方面的变化。虽然总体人群的知识水平有了显著提高，一些人报告称减少了危险行为，但无法将这些变化归因于该项目本身。
