[目的/意义] 探索突发公共卫生事件中农村中老年人向正在接受高等教育的子辈寻求事件相关信息的代际反哺行为及其形成过程，以期为农村地区的风险信息的传播构建新路径，同时亦为政府部门进行乡村治理提供可实践的思路。[方法/过程] 基于动机信息管理理论，重点关注突发公共卫生事件中农村中老年人的不确定性差异、焦虑、结果预期和效能是否会影响他们的信息寻求行为。同时，在获得相关信息后，他们是否会表现出信息采纳和信息传递的行为。在新冠肺炎疫情发生期间，利用问卷调查法收集数据，通过统计分析软件进行研究假设的验证。[结果/结论] 通过分析发现，不确定性差异会引起农村中老年人的焦虑，进而影响其结果预期和效能，最后触发他们的信息寻求行为。他们亦会采纳和传递所获取的信息，以达到共同防疫的目的。

During the COVID-19 outbreak, the data was collected through the use of online survey and analysed by the statistical software.[Result/conclusion] The results reveal that uncertainty discrepancy can affect anxiety, and further negatively influence outcome assessments and efficacy. The information seeking behavior could be affected by efficacy. Additionally, they tend to adopt and forward the obtained information to prevent themselves together.
