In 2002 MTV launched a global multicomponent HIV prevention campaign, "Staying Alive," reaching over 166 countries worldwide. An evaluation of this campaign focused on three diverse sites: Kathmandu, Nepal; São Paulo, Brazil; and Dakar, Senegal. Data were collected before and after campaign implementation through population-based household surveys. Using linear regression techniques, our evaluation examined the effects of campaign exposure on interpersonal communication about HIV and the effects of campaign exposure and interpersonal communication on beliefs about HIV prevention. We found a consistent positive effect of exposure on interpersonal communication across all sites, though there were differences among sites with regard to whom the respondent talked about HIV. We also found a consistent positive effect of exposure on HIV prevention beliefs across sites when interpersonal communication was simultaneously entered into the model. Finally, in two sites we found a relationship between interpersonal communication and HIV prevention beliefs, controlling for exposure, though again, the effects differed by the type of person the communication was with. These similar findings in three diverse sites provide ecological validity of the findings that "Staying Alive" promoted interpersonal communication and influenced young people's beliefs about HIV prevention in a positive way, evidence for the potential of a global media campaign to have an impact on social norms.
2002年,MTV发起了一项全球性的多层面艾滋病病毒预防运动——“继续活着”,覆盖全球166个以上的国家。对该运动的一项评估聚焦于三个不同地点:尼泊尔加德满都、巴西圣保罗和塞内加尔达喀尔。通过基于人群的家庭调查在运动实施前后收集数据。运用线性回归技术,我们的评估考察了接触该运动对艾滋病病毒人际交流的影响,以及接触运动和人际交流对艾滋病病毒预防信念的影响。我们发现,在所有地点,接触该运动对人际交流都有一致的积极影响,不过在受访者与谁谈论艾滋病病毒方面,各地点存在差异。当人际交流同时纳入模型时,我们还发现,在所有地点,接触该运动对艾滋病病毒预防信念都有一致的积极影响。最后,在两个地点,我们发现人际交流与艾滋病病毒预防信念之间存在关联,排除了接触运动的影响,不过同样,根据交流对象的类型,影响也有所不同。在三个不同地点的这些相似发现,为“继续活着”运动促进人际交流并以积极方式影响年轻人对艾滋病病毒预防的信念这一研究结果提供了生态学效度,证明了全球媒体运动对社会规范产生影响的潜力。
