It is important to understand people's risk perception to identify effective pathways for risk communication about per- and polyfluoroalkyl substances (PFAS) because they present emerging environmental health risks. Guided by dual-process theories of information processing, this study focuses on as a key variable that influences risk perception, systematic processing, and information seeking intention. Through an experimental survey, we found that participants in the high personal relevance condition ( = 497) were more likely to process information systematically compared to those in the low personal relevance condition ( = 486). Results also revealed that personal relevance influenced systematic processing through risk judgment and emotional response. Message-specific systematic processing was positively associated with information seeking intention. Lastly, trust in government and trust in science had different relationships with systematic processing, demonstrating the importance of distinguishing different types of institutional trust in future research.
了解人们的风险感知对于确定有关全氟和多氟烷基物质 (PFAS) 的风险沟通的有效途径非常重要，因为它们构成了新出现的环境健康风险。本研究以双过程信息处理理论为指导，将个人相关性作为影响风险感知、系统处理和信息寻求意愿的关键变量。通过实验调查，我们发现高个人相关性条件下的参与者（n=497）比低个人相关性条件下的参与者（n=486）更倾向于系统地处理信息。结果还表明，个人相关性通过风险判断和情绪反应影响系统处理。特定于信息的系统处理与信息寻求意愿呈正相关。最后，对政府的信任和对科学的信任与系统处理的关系不同，这表明在未来的研究中区分不同类型的机构信任非常重要。
