社交媒体正迅速成为传播紧急预警信息的首选渠道。然而，相对较少的数据驱动的研究存在，以告知有效的信息设计时，使用这些媒体。本研究通过检查公共安全机构在2013年科罗拉多州博尔德洪水期间通过Twitter发送的简短的健康相关警告信息来解决这一问题。在为期5天的洪水期间，对来自52个Twitter账户的5,100条推文进行了检查，得出了几个关键结论和影响。首先，在我们的研究中，地方应急管理领导人发布的公共卫生信息最常被组织转发。第二，在这一事件中，紧急公共卫生信息主要集中在饮用水方面。第三，简洁的信息可以设计成包括命令/指导和声明/解释的内容风格，这两者对于在危机期间促进公共卫生都是必不可少的。这些发现表明，即使是通过Twitter传递的简短消息也应该提供有关危险事件及其影响的信息，以及自我保护的可操作指示。
Social media are quickly becoming the channel of choice for disseminating emergency warning messages. However, relatively little data-driven research exists to inform effective message design when using these media. The present study addresses that void by examining terse health-related warning messages sent by public safety agencies over Twitter during the 2013 Boulder, CO, floods. An examination of 5,100 tweets from 52 Twitter accounts over the course of the 5-day flood period yielded several key conclusions and implications. First, public health messages posted by local emergency management leaders are most frequently retweeted by organizations in our study. Second, emergency public health messages focus primarily on drinking water in this event. Third, terse messages can be designed in ways that include imperative/instructional and declarative/explanatory styles of content, both of which are essential for promoting public health during crises. These findings demonstrate that even terse messages delivered via Twitter ought to provide information about the hazard event, its impact, and actionable instructions for self-protection.
