摘　　要：目的:探究RISP模型如何预测公众搜寻新冠肺炎信息的意图,以期为推动公众正确寻求科学合理的新冠肺炎疫情风险信息提供参考。方法:采用问卷调查公众新冠肺炎疫情风险信息搜寻与加工行为的相关问题,并基于RISP模型提出研究假设,构建结构方程模型。结果:模型各维度之间具有良好的区别效度,模型拟合度亦符合要求;受教育程度与对大众媒体渠道的信任呈正相关(β=0.225),年龄与对社交媒体渠道和个人信息渠道的信任均呈正相关(β=0.156和β=0.271),知觉风险特征与情感响应存在正相关(β=0.663);公众在面对新冠肺炎疫情时的信息处理存在同时采用启发式处理和系统式处理的可能;信息不足与信息搜寻呈正相关(β=0.017),感知信息收集能力与当前知识呈正相关(β=0.317),对大众媒体、社交媒体渠道的信任与系统式处理均呈正相关(β=0.693、β=0.305),对社交媒体、个人信息渠道的信任则与启发式处理均呈正相关(β=0.545和β=0.603)。结论:信息不足是公众搜寻新冠肺炎信息的主要动力;公众的负面情绪与其对新冠肺炎风险的感知有关;受教育程度影响居民对大众媒体的信任,年龄则影响居民对社交媒体和个人信息渠道的信任;对大众媒体和社交媒体的信任与系统式处理呈正相关,对社交媒体和个人信息渠道的信任与启发式处理呈正相关。Objective:To explore how the RISP model predicts the public's intention to search for information on COVID-19,in order to provide a reference for promoting the public to correctly seek scientific and reasonable information on the risk of COVID-19.Methods:A questionnaire survey was used to investigate the public's COVID-19 epidemic risk information search and processing behavior related issues,and based on the RISP model to propose research hypotheses,and construct a structural equation model.Results:The model had good discriminative validity among the various dimensions,and the model fit was also in line with the requirements;education level was positively correlated with trust in mass media channels(β=0.225),age was positively correlated with trust in social media channels and in personal information channels(β=0.156 andβ=0.271),perceived risk characteristics and emotional response were positively correlated(β=0.663);the public might use heuristic processing and systematic processing at the same time in information processing in the face of the COVID-19 epidemic;insufficient information was positively correlated with information search(β=0.017),the ability to collect perceptual information was positively correlated with current knowledge(β=0.317),the trust in mass media and social media channels was positively correlated with systematic processing(β=0.693,β=0.305),and the trust in social media and personal information channels was positively correlated with heuristic processing(β=0.545 andβ=0.603).Conclusion:Insufficient information is the main driving force for the public to search for information on COVID-19;public negative emotions are related to their perception of COVID-19 risk;education level affects residents'trust in mass media,and age affects residents'trust in social media channels and personal information channels;trust in mass media and social media is positively related to systematic processing,and trust in social media and personal information channels is positively related to heuristic p
