Data from the article: Narrative Risk Communication as a Lingua Franca for Environmental Hazard Preparation

Incorporating narrative elements into risk communication may encourage preparation for environmental hazards in ways that scientific language alone does not. We integrate narrative theory, narrative persuasion, and risk theories into a Narrative Risk Communication Framework and then assess the effectiveness of character selection as a narrative mechanism in scientific risk communication as compared to conventional science messaging alone. We utilize a survey experiment with residents along the flood-prone Yellowstone River in Montana and analyze the resulting data with a parallel and serial mediation statistical model. We find that positive affective response mediates the influence of narratives featuring hero character language. Positive affective response appears to overcome the risk perception paradox both by circumventing rational analysis of risk and by shaping risk perception. Overall, the results suggest that inspirational hero language is superior to language of fear or victimization in encouraging preparation – an important lesson for practitioners working to help citizens prepare for environmental disasters.

Methods
The dataset resulted from a survey experiment conducted with residents who lived within 800 meters of the Yellowstone River in Montana. The survey yielded 3,320 responses out of 8,721 mailings, for a response rate of 38.1%. After cleaning to remove addresses that did not contain a residence or for which the respondent was not an owner, trustee, or administrator of the property, 2,901 responses remained as valid. The primary data analysis involved a parallel and serial mediation model. Data and instructions are supplied to replicate that model. The number of observations used in the modeling, after eliminating missing data, is 1,938.

将叙事元素融入风险沟通，或可通过仅靠科学语言无法实现的路径，推动民众为环境灾害做好防灾准备。我们将叙事理论、叙事说服理论与风险理论整合至叙事风险沟通框架（Narrative Risk Communication Framework），随后对比仅采用传统科学传播的方式，评估了科学风险沟通中作为叙事机制的角色选择方案的有效性。我们针对蒙大拿州易受洪水侵袭的黄石河沿岸居民开展了调查实验，并采用并行与链式中介统计模型对所得数据进行分析。研究发现，积极情感反应在英雄角色叙事语言的影响路径中起到中介作用。积极情感反应似乎可通过规避风险的理性分析、重塑风险认知两种途径，破解风险感知悖论。总体而言，研究结果表明，相较于传递恐惧或受害者叙事的措辞，鼓舞人心的英雄叙事语言更能有效推动防灾准备——这对于致力于帮助民众应对环境灾害的从业者而言，是一项极具价值的经验启示。

研究方法
本数据集源自针对蒙大拿州黄石河沿岸800米范围内居民开展的调查实验。本次调研共寄出8721份调查问卷，回收有效响应3320份，响应率达38.1%。在剔除无居住地址的样本，以及受访者并非该物业所有者、受托人或管理者的问卷后，最终保留2901份有效样本。核心数据分析采用并行与链式中介模型。本数据集及相关操作说明已公开，可用于复现该模型。在剔除缺失值后，建模所用的有效观测样本量为1938。
