Developing an evaluation tool for disaster risk messages

Abstract: Purpose – Risk communication is a critical component of individual health decision making and behavior. In disaster situations, it is crucial that risk-related messages are communicated accurately and that they reach and inform target audiences about the steps they can take to protect their health. Despite a global recognition of the importance of risk communication in responding to disasters, there remains a dearth of evidence on how to evaluate the effectiveness of risk communication messages… Show more

“…As others have argued, although guidelines help identify aspects of materials to be improved, their value is diminished without corresponding efforts to test usability with target audiences. 12,17 Moving forward, communities' actions toward improving the predisaster information environment can be evaluated for their success in effecting behavior change (both in real-time and following actual disasters) using emergent tools (see 39,40 ).…”

“…The reason may be our sample of English language journals, language barriers, or differences in internet and social media use. Yet only three studies focus on Canadian social media users or cases (Bergeron & Friedman 2015;Saleem, Xu & Ruths 2014), one of which also includes data from twenty-one other countries (Murthy & Longwell 2012). A fourth reason for this identified gap may be differences regarding the research paradigms and concepts used.…”

“…The empirical findings support entropy as a valid measure of uncertainty. First, as a disaster tweetʼs entropy increases, its retweet count decreases-uncertain tweets are likely to be less clearly communicated (Bergeron & Friedman, 2015) and thought to convey less sufficient information (Mileti & Sorensen, 1990), negatively influencing retweeting. This result demonstrates that entropy captures the essential characteristic of uncertainty in the context of Twitter for disaster communication.…”

“…It seems like just enough to terrify you, but not to really help you do anything" (p. 6). The literature on disaster communication defines two requirements for disaster messages: (i) clear and accurate communication (Bergeron & Friedman, 2015) and (ii) sufficient information (Mileti & Sorensen, 1990). Viewed in this light, a tweetʼs limited length is a doubleedged sword-a facilitator to quickly post and repost tweets, but a restrictor to convey the amount of information per tweet.…”
