Rethinking Risk Perception and its Importance for Explaining Natural Hazard Preparedness Behavior.

Abstract

Psychological theory suggests there is a positive association between risk perception and protective behavior. Empirical research has, however, found mixed support for the positive link between risk perception and protective behavior. One explanation for the inconsistent link is the way in which risk perception has been conceptualized and/or operationalized in past research. Specifically, few studies acknowledge differences in hazard severity and how it might affect risk perception and protective behavior. Past research has also tended to overlook the importance of emotional appraisal in relation to perceived hazard consequences. To address these inconsistencies in past research, 337 people living in a cyclone-prone location were recruited to participate in an online study. In this study, respondents were randomly presented with one of five hypothetical cyclone scenarios, which differed in objective severity. Respondents were also presented with a survey, which assessed risk perception, protective action perceptions (or coping appraisal), and intentions to perform short-term protective behaviors. As hypothesized, risk perception significantly increased preparedness intentions when controlling for hazard severity, hazard probability, and protective action perceptions. Moreover, the degree to which respondents associated negative emotions with predicted damage was also a relatively strong predictor of preparedness intentions. Overall, the findings support the theoretical link between risk perception and protective behavior and provide a new method of assessing risk perception in cross-sectional research. On a practical level, the results suggest that increasing risk perception should promote protective behavior in response to natural hazards.
