Operationalizing risk perception and preparedness behavior research for a multi-hazard context

Abstract

Increasingly, citizens are being asked to take a more active role in disaster risk reduction (DRR), as decentralization of hazard governance has shifted greater responsibility for hazard preparedness actions onto individuals. Simultaneously, the taxonomy of hazards considered for DRR has expanded to include medical and social crises alongside natural hazards. Risk perception research emerged to support decision--makers with understanding how people characterize and evaluate different hazards to anticipate behavioral response and guide risk communication. Since its inception, the risk perception concept has been incorporated into many behavioral theories, which have been applied to examine preparedness for numerous hazard types. Behavioral theories have had moderate success in predicting or explaining preparedness behaviors; however, they are typically applied to a single hazard type and there is a gap in understanding which theories (if any) are suited for examining multiple hazard types simultaneously. This paper first reviews meta--analyses of behavioral theories to better understand performance. Universal lessons learnt are summarized for survey design. Second, theoretically based preparedness studies for floods, earthquakes, epidemics, and terrorism are reviewed to assess the conceptual requirements for a 'multi--hazard' preparedness approach. The development of an online preparedness self--assessment and learning platform is discussed.

Culture matters: Factors influencing natural hazard risk preparedness – a survey of Swiss households

“…This defines preparedness as a combination of social capacities and reads similar to the above introduced IRM principle and the definition of social capacity. Many of these concepts and definitions used in risk research lack distinct meanings (Shreve and Fordham, 2016), which reflects the change of paradigms and rationales Nat. Hazards Earth Syst.…”

An integrated approach to mental health and disaster preparedness: a cluster comparison with earthquake affected communities in Nepal

“…There is some evidence to suggest that reasons for this may in part be psychological in nature and dependent on social context [ 7 , 12 – 15 ]. Risk perception literature indicates that preparedness behaviors are likely linked to perceived risk of severity and personal vulnerability, ability to prepare (efficacy), and likelihood that specific behaviors will actually mitigate risk [ 16 , 17 ]. Associated research underscores the importance of considering demographic variables, including types of vulnerability, when examining engagement in preparedness.…”

“…Across hazard types examined, preparedness actions taken were minimal and frequently related to lower cost measures such as stockpiling food and emergency supplies with some exceptions; these actions are beneficial in the initial disaster recovery phase, but then have no substantive benefit for mitigation. Relatively recent community-level models of hazard preparedness, which map the complexity of individual and relational factors leading to hazard preparedness behaviors such as Paton (2003Paton ( , 2008, capture the dominant cognitive, normative, and social factors identified in the risk perception literature influencing people's preparedness behaviors, therefore providing a useful tool for local emergency/disaster risk managers (Shreve et al, 2016).…”
