ABSTRACT

The Gulf coast is losing land to erosion at a rapid rate. Applying the planned risk information seeking model (PRISM; Kahlor, L. (2010). PRISM: A planned risk information seeking model. Health Communication, 25(4), 345–356), this survey research examines the cognitive and affective determinants of individuals’ intention to seek information about Gulf coastal erosion, and the moderation effect of geographic distance on the proposed relationships through multigroup Structural Equation Modeling. Results showed that PRISM performs well in this novel context, confirming its robustness. Further, the relationship between knowledge insufficiency and information seeking intent was stronger for Gulf residents than residents of other states. The results suggested that PRISM can increase its explanatory power by including a psychological distance factor. Also, communication about Gulf coastal erosion to local residents should focus on their lack of knowledge of this risk.

摘要

墨西哥湾沿岸的土地正在以快速的速度流失。应用计划的风险信息搜索模型（PRISM； Kahlor，L.（2010）。PRISM：计划的风险信息搜索模型。Health Communication，25（4），345-356），这项调查研究考察了个人意图寻求有关海湾沿岸侵蚀信息的认知和情感决定因素，以及通过多组结构方程模型对拟议关系进行地理距离调节的影响。结果表明，PRISM在这种新颖的环境中表现良好，证实了其鲁棒性。此外，海湾居民的知识不足与信息寻求意图之间的关系比其他州的居民要强。结果表明，PRISM可以通过包括心理距离因素来提高其解释力。另外，与墨西哥湾居民进行的有关墨西哥湾沿岸侵蚀的交流应着重于他们对这种风险的了解不足。
