Social media is becoming increasingly integrated into disaster response communication strategies of public health and emergency response agencies.
We sought to assess the content, accessibility, and dissemination of social media communications made by government agencies during a disaster response.
A cross-sectional analysis of social media posts made by federal, state, and local government, public health and emergency management agencies before, during, and after the 2016 Louisiana floods was conducted to determine their content, accessibility, and dissemination by level of government and time relative to disaster onset.
Facebook and/or Twitter posts made by public agencies involved in the response to the 2016 Louisiana Flooding events (FEMA Disaster Declaration [DR-4277]) published between August 4 and September 16, 2016, publicly available online between February 21 and March 31, 2017, were included in the analysis.
Content: The text of each post was assessed to determine whether it contained information on provision of situational awareness; addressing misconception, actionable requests; mental, behavioral, and emotional support; and/or recovery and rebuilding resources. Accessibility: A Flesh-Kincaid grade level of each post was calculated, and information on post language, originality, hyperlinks, visuals, videos, or hash tag was recorded. Dissemination: The average number of reacts/likes, shares/retweets, and comments per post was calculated.
Most posts contained information related to situational awareness and recovery resources. There was an increase in messages during the first week of the disaster at all levels. Few posts were made in languages other than English. Compared with state and federal posts, local Facebook posts averaged fewer reacts, comments, and shares throughout the analysis period.
Government agencies may maximize the use of social media platforms for disaster communications by establishing their social media network in advance of a disaster and by applying established guidelines on disaster social media use.
社交媒体在公共卫生和应急响应机构的灾害应对通信策略中变得越来越重要。
我们旨在评估政府机构在灾害应对期间发布的社交媒体通讯的内容、可访问性和传播情况。
对联邦、州和地方政府、公共卫生和应急管理机构在 2016 年路易斯安那州洪水之前、期间和之后发布的社交媒体帖子进行了横断面分析，以确定其内容、可访问性以及按政府级别和相对于灾害发生的时间进行传播。
包括 2016 年路易斯安那州洪水事件（FEMA 灾害声明 [DR-4277]）期间公共机构发布的 Facebook 和/或 Twitter 帖子，这些帖子在 2016 年 8 月 4 日至 9 月 16 日期间发布，在 2017 年 2 月 21 日至 3 月 31 日期间在线公开，分析中包含这些帖子。
内容：评估每个帖子的文本，以确定其是否包含有关提供态势感知、解决误解、可操作请求、心理、行为和情感支持以及/或恢复和重建资源的信息。可访问性：计算每个帖子的 Flesh-Kincaid 年级水平，并记录帖子语言、原创性、超链接、视觉效果、视频或哈希标记的信息。传播：计算每个帖子的平均点赞/喜欢、分享/转发和评论数。
大多数帖子包含有关态势感知和恢复资源的信息。在灾害的第一周，所有级别都增加了信息。很少有帖子用英语以外的语言发布。与州和联邦帖子相比，地方 Facebook 帖子在整个分析期间的点赞、评论和分享平均数都较少。
政府机构可以通过在灾害发生前建立社交媒体网络并应用有关灾害社交媒体使用的既定指南，最大限度地利用社交媒体平台进行灾害通信。
