这项研究的目的是通过分析2016-2017年间美国寨卡病毒小规模爆发期间报道的不同媒体来源和渠道(或称“曲目”),更好地了解媒体关注对美国人风险认知的影响。我们使用一个由美国成年人组成的在线小组,分析了从2016年7月19日到2017年4月24日这九个月的四波纵向小组研究的调查数据。媒体关注个人风险、美国风险和采取行动的必要性。报道的对国际报道的关注更增加了个人风险,某些报道的网站关注降低了个人风险,但报道的对公共卫生机构网站的关注增加了个人风险。美国的风险因报道对国内和国际报道的关注而增加,而电视报道则减少了这一关注。对美国采取行动的判断需要更多地通过接触国内报道来增强,通过报道对电视和当地报纸的关注而减少,但通过报道对BBC和CNN的接触而增强。我们的结果表明,在2016-2017年寨卡病毒爆发期间,使用不同的媒体渠道和来源与对风险和行动需求的不同看法是如何相关的。
The objective of this study is to better understand the effects of media attention on Americans’ perceptions of risk by analyzing the different media sources and outlets, or “repertoires,” reported as used during the small 2016–2017 Zika outbreak in the U.S. We analyzed survey data from a four-wave longitudinal panel study over nine months – July 19, 2016 through April 24, 2017 (n = 743) – using an online panel of American adults. Media attention related to ratings of personal risk, U.S. risk, and need for action. Personal risk was enhanced more by reported attention to international coverage, reduced by certain reported website attention, but enhanced by reported attention to public health agency websites. U.S. risk was enhanced by reported attention to both domestic and international coverages, reduced by television. Judged need for U.S. action was enhanced more by exposure to domestic coverage, reduced by reported attention to television and local newspapers, but enhanced by reported exposure to BBC and CNN. Our results demonstrate how the use of different media outlets and sources are related to different perceptions of risk and need for action during 2016–2017 Zika outbreak.
