Canadians' Representation of Chemical, Biological, Radiological, Nuclear, and Explosive (CBRNE) Terrorism: A Content Analysis

ABSTRACT The global threat of terrorism raises questions about preparedness and risk communication in the context of public health and security. Although experts discriminate between chemical, biological, radiological, nuclear, and explosive (CNRNE) terrorist events, little is known about how the Canadian public represents these forms of terrorism. A stratified random sample of 1502 Canadians participated in a telephone survey on CBRNE terrorism. A word association technique was used to assess first words or images that came to mind while thinking about different types of terrorist scenarios. Content analysis of this data revealed a number of potential uncertainties and misconceptions regarding different types of terrorism scenarios. Despite most frequently providing agents in response questions surrounding chemical or biological terrorism, respondents frequently confounded agents of biological and chemical nature. Similarly, different aspects of nuclear events were not consistently distinguished. Most notably, however, a sizable proportion of respondents had difficulty providing word associations to the different types of terrorist events or only provided vague responses that closely mirrored the scenario in question. Finally, images regarding the potential impacts of scenarios were infrequent. Implications for risk communication and preparedness are discussed; in particular, the need to provide the public with more detailed information regarding the nature of different forms of CBRNE terrorism and how to best prepare for a potential event.
