这项大规模的互联网实验测试了疫苗关键网页是否会提高人们对疫苗接种风险的认识，并改变疫苗接种意图。我们操纵了信息环境（疫苗关键网站，控制，两者）和搜索的重点（疫苗接种风险，遗漏风险，没有重点）。我们的分析表明，访问疫苗关键网站5到10分钟会增加对疫苗接种风险的感知，并降低对遗漏疫苗接种风险的感知以及接种疫苗的意图。与“风险感受”方法一致，疫苗关键网站引起的影响与风险感知的变化呈正相关。
This large-scale Internet-experiment tests whether vaccine-critical pages raise perceptions of the riskiness of vaccinations and alter vaccination intentions. We manipulated the information environment (vaccine-critical website, control, both) and the focus of search (on vaccination risks, omission risks, no focus). Our analyses reveal that accessing vaccine-critical websites for five to 10 minutes increases the perception of risk of vaccinating and decreases the perception of risk of omitting vaccinations as well as the intentions to vaccinate. In line with the 'risk-as-feelings' approach, the affect elicited by the vaccine-critical websites was positively related to changes in risk perception.
