This research examines the impact of exposure to online blogs about the human papillomavirus (HPV) vaccine on vaccine-related risk perceptions, attitudes, and behavioral intentions. In a controlled experiment (N = 341), college students were exposed to either a negative blog post about the HPV vaccine or a positive one. Compared to the control group, participants who had viewed the negative blog perceived the vaccine as less safe, held more negative attitudes toward the vaccine, and had reduced intentions to receive the vaccine. In contrast, exposure to the positive blog did not alter any vaccine-related risk perceptions, attitudes, or intentions. Implications of the findings for online vaccine risk communication are discussed.
本研究考察了接触关于人乳头瘤病毒（HPV）疫苗的在线博客对疫苗相关风险认知、态度和行为意向的影响。在一项对照实验中（N=341），大学生接触了关于 HPV 疫苗的负面或正面博客文章。与对照组相比，观看负面博客的参与者认为疫苗安全性较低，对疫苗的态度较负面，接种疫苗的意愿降低。相比之下，接触正面博客并没有改变任何与疫苗相关的风险认知、态度或意向。讨论了这些发现对在线疫苗风险沟通的意义。
