Although there is enough scientific evidence to show the benefits and safety of vaccines, vaccine rates are low, while misperceptions about vaccines are on the rise. The main purposes of the current study are to 1) examine the effects of narrative vs. statistical messages on vaccine intention, 2) test the mediating role of perceived expectancies, and 3) examine the moderating roles of perceived susceptibility and misperceptions on vaccine intention. Data were collected with an online experiment through Amazon Mturk. The online experiment was conducted via Qualtrics once the study was considered exempt by the Institutional Research Board of a large University in the U.S. A total of 300 participants aged 18 and above completed the survey. Findings show that perceived expectancies mediate the relationship between message manipulation and vaccine intention. Our findings also show a three-way interaction which indicates that among individuals with high misperceptions, statistical messages are more persuasive for individuals with high perceived susceptibility, while narrative messages are more influential for individuals with low perceived susceptibility.
尽管有足够的科学证据表明疫苗的益处和安全性，但疫苗接种率较低，而对疫苗的误解却在增加。本研究的主要目的是：1）检验叙事性信息与统计性信息对疫苗接种意愿的影响；2）测试感知预期的中介作用；3）检验感知易感性和误解对疫苗接种意愿的调节作用。通过亚马逊的Mechanical Turk进行在线实验收集数据。一旦该研究被美国一所大型大学的机构研究委员会认定为豁免研究，便通过Qualtrics进行在线实验。共有300名18岁及以上的参与者完成了调查。研究结果表明，感知预期在信息操纵与疫苗接种意愿之间起中介作用。我们的研究结果还显示了一种三方交互作用，这表明在误解程度高的个体中，统计性信息对感知易感性高的个体更具说服力，而叙事性信息对感知易感性低的个体更具影响力。
