To develop a new measure of preferred sources for risk information, two studies asked respondents to indicate what channels they were reliant on for information about COVID-19, from 25 news channels ranging across the political spectrum. Unexpectedly, dependencies clustered around level of reliability rather than the political orientation of the news channel. In other words, each cluster included media channels from both the left and right side of the political spectrum, while dependencies clustered into sources that varied by the degree to which their content is reliable. Participants who turned to lower reliability channels indicated lower risk perceptions, less accurate probability estimations, reduced vaccination intentions, and lower protective behavioral intentions. Those inclined to use higher reliability channels indicated higher risk perceptions, more accurate probability estimations, increased vaccination intentions, and higher protective behavioral intentions. These relationships are discussed in terms of implications for our understanding of source reliance and risk perception, information sufficiency, and implications for both future research and public health interventions.
为了开发一种新的风险信息首选来源的衡量指标,两项研究要求受访者指出他们依赖哪些渠道来获取有关 COVID-19 的信息,这些渠道来自政治光谱广泛的 25 个新闻频道。出乎意料的是,依赖关系集中在可靠性水平上,而不是新闻频道的政治取向。换句话说,每个集群都包括来自政治光谱左右两侧的媒体渠道,而依赖关系则分为因内容可靠性程度而异的来源。转向低可靠性渠道的参与者表示风险感知较低,概率估计准确性较低,疫苗接种意愿降低,保护性行为意图降低。那些倾向于使用更高可靠性渠道的人表示风险感知更高,概率估计更准确,疫苗接种意愿增加,保护性行为意图更高。这些关系是根据对我们对来源依赖和风险感知、信息充足性的理解以及对未来研究和公共卫生干预的意义来讨论的。
