Developing an evaluation tool for disaster risk messages
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. The purpose of this paper is to develop and assess a pilot tool to evaluate the effectiveness of disaster risk messages. Design/methodology/approach – A pilot evaluation tool was developed using the existing risk communication literature. An expert assessment of the tool was conducted using an open-ended survey and a focus group discussion with 18 experts at the Public Health Agency of Canada in February 2013. Findings – The tool measures content, reach, and comprehension of the message. It is intended to be a quick, internal evaluation tool for use during a disaster or emergency. The experts acknowledged the practicality of the tool, while also recognizing evaluation challenges. Research limitations/implications – This pilot exploratory tool was assessed using a relatively small sample of experts. Practical implications – This tool offers public health and disaster preparedness practitioners a promising approach for evaluating and improving the communication and management of future public health emergencies. Originality/value – This is the first practical tool developed to evaluate risk communication messages in disaster situations.
