Deanna D. Sellnow is professor of communication in the Nicholson School of Communication at the University of Central Florida. Dr. Sellnow’s research focuses on strategic instructional communication in a variety of contexts including risk, crisis, health, and online settings. She has conducted funded research for the United States Geological Survey, Department of Homeland Security, and Centers for Disease Control and Protection. She has also collaborated with agencies such as the International Food Information Council about food security across the globe. She has published her work in numerous refereed articles in national and international journals, as well authored or co-authored several textbooks including Effective Speaking in a Digital Age, Communicate!, and The Rhetorical Power of Popular Culture.


Effective Crisis and Risk Communication Message Design:
Considering Ecological Validity

Although internal and external validity are critical to any high quality social scientific research study, we argue that ecological validity is equally important when formulating and testing crisis and risk communication messages. To achieve ecological validity, the methods, materials, and setting must be representative of the real-world crisis or risk situation being examined. When designing and testing instructional crisis and risk messages intended to achieve affective, cognitive, and behavioral learning, we contend that ecological validity ought to be addressed from the outset, that is, when designing messages and measurement tools. In this session, we illustrate how we attempted to accomplish ecological validity by describing the participatory processes we employed in two funded research projects. First, we invited participation from food scientists, professional television news broadcasters, and communication experts when designing mock television news stories intended to empower receivers to make informed choices for self-protection regarding tainted food products. Second, we facilitated a design storm involving seismologists, emergency managers, engineers, graphic designers, and communication experts to develop earthquake early warning messages delivered via a phone app. Through this participatory approach, these projects more closely emulate real-life crisis and risk communication challenges and allow for more valid measurement of audience perceptions.
In this session, we will share the insights gleaned from these two research projects.


General Session: Urgent Crisis Communication: Designing Effective Earthquake Warning Messages*

In high risk and crisis situations, receiving the right message at the right time can save lives. Natural disasters certainly qualify as crisis events.  Few natural disasters are more constrained by short response time for warning potential victims as earthquakes. Once an earthquake begins, officials often have only a few seconds or minutes to warn people and communities located near the quake’s epicenter that potentially deadly shaking is going to begin and provide instructions for self-protection. To meet this challenge, the United States Geological Survey turned to crisis communication experts and visual communication specialists to design effective early warning messages that can be delivered via a smart phone APP. Given the extremely short time span available to get earthquake warning messages out, such messages must be immediately recognizable, tailored appropriately, and clearly instructive in terms of self-protection.

This project faces several constraints inherent in many crisis contexts. For example, sharing probabilities to help people comprehend their level of risk is constrained by a wide disparity in how probabilities are interpreted. Moreover, disparate levels of risk science literacy and number sense literacy among people and groups create comprehension disparity constraints. Still another constraint stems from the fact that we live in a world where a worried public demands certainty about scientific information regarding potential crises that cannot be fully comprehended. Those charged with communicating early warning messages about earthquakes are challenged by these constraints. This project seeks to address these constraints by merging instructional risk and crisis communication literature and visual design techniques with seismology science information to create, test, and improve early warning and operational forecasting messages about earthquakes. Ultimately, designing and implementing effective instructional risk and crisis communication messages about earthquakes has the potential to save lives.

The presentation proposed will describe how Sellnow and Sellnow have addressed these constraints in developing early warning messages for this project. They will also share sample messages and provide statistical results of their initial round of message testing. Finally, they will generalize beyond our project to include a discussion of practical applications for addressing the consistent constraints of creating warning messages in crisis contexts.
