UNASSIGNED: In this study, we conducted two web-based longitudinal surveys in Japan (PHASE 1, 1-30 November 2020, 6,000 participants; PHASE 2, 1-31 December 2020, 3,800 participants). We characterised segments of the target population using cluster analysis on health literacy and beliefs regarding COVID-19 obtained in PHASE 1. We further investigated the associations between the clusters and infection prevention/risk-taking behaviours and fear of COVID-19, obtained from PHASE 2.
UNASSIGNED: Five clusters were identified: \'Calm/hoax denial\', \'Hoax affinity/threat denial\', \'Minority/indifference\', \'Over vigilance\', and \'Optimism\'. There were significant differences in infection prevention/risk-taking behaviours and fear of COVID-19 among the five clusters. The belief in susceptibility to infection, rather than affinity for hoaxes and conspiracy theories, was coherently associated with infection prevention/risk-taking behaviours and fear of infection across clusters. This study provides foundational knowledge for creating segment-specific public messages and developing interactive risk communication to encourage infection prevention behaviours.
■在这项研究中,我们在日本进行了两项基于网络的纵向调查(第一阶段,2020年11月1-30日,6,000名参与者;第二阶段,2020年12月1-31日,3,800名参与者)。我们使用阶段1中获得的关于COVID-19的健康素养和信念的聚类分析,对目标人群的部分进行了表征。我们进一步调查了从第二阶段获得的集群与感染预防/冒险行为和对COVID-19的恐惧之间的关系。
■确定了五个群集:\'冷静/骗局拒绝\',\'骗局关联/威胁拒绝\',\'少数/冷漠\',\'过度警惕\',和“乐观”。在这五个集群中,感染预防/冒险行为和对COVID-19的恐惧存在显着差异。对感染易感性的信念,而不是对恶作剧和阴谋论的亲和力,与跨集群的感染预防/冒险行为和对感染的恐惧密切相关。这项研究为创建特定部门的公共信息和开发交互式风险沟通以鼓励感染预防行为提供了基础知识。
