Recent flood risk management puts an increasing emphasis on the public's risk perception and its preferences. It is now widely recognized that a better knowledge of the public's awareness and concern about risks is of vital importance to outline effective risk communication strategies. Models such as Risk Information Seeking and Processing address this evolution by considering the public's needs and its information-seeking behavior with regard to risk information. This study builds upon earlier information-seeking models and focuses on the empirical relationships between information-seeking behavior and the constructs of risk perception, perceived hazard knowledge, response efficacy, and information need in the context of coastal flood risks. Specific focus is given to the mediating role of information need in the model and to the differences in information-seeking behavior between permanent and temporary residents. By means of a structured on-line questionnaire, a cross-sectional survey was carried out in the city of Ostend, one of the most vulnerable places to coastal flooding on the Belgian coast. Three hundred thirteen respondents participated in the survey. Path analysis reveals that information need does not act as a mediator in contrast to risk perception and perceived knowledge. In addition, it is shown that risk perception and perceived hazard knowledge are higher for permanent than temporary residents, leading to increased information-seeking behavior among the former group. Implications for risk communication are discussed.
最近的洪水风险管理越来越强调公众的风险感知及其偏好。现在人们广泛认识到,更好地了解公众对风险的意识和关注对于制定有效的风险沟通策略至关重要。风险信息寻求与处理等模型通过考虑公众对风险信息的需求及其信息寻求行为来应对这种演变。本研究建立在早期的信息寻求模型基础上,重点研究了在沿海洪水风险背景下,信息寻求行为与风险感知、感知危害知识、应对效能和信息需求等结构之间的实证关系。特别关注信息需求在模型中的中介作用以及永久性和临时性居民在信息寻求行为上的差异。通过在线结构化问卷,在比利时海岸最易受沿海洪水影响的城市奥斯坦德进行了横断面调查。有 313 名受访者参与了调查。路径分析表明,与风险感知和感知知识不同,信息需求不起中介作用。此外,研究还表明,永久性居民的风险感知和感知危害知识高于临时性居民,导致前者群体的信息寻求行为增加。讨论了风险沟通的影响。
