This study examines the effect of risk communication styles (fear-based versus empowerment-based) on households' earthquake preparedness. An online longitudinal study with intervention and control groups was conducted using a representative sample of the adult population in Israel. The change in the reported level of preparedness was assessed through Repeated Measures ANOVA with interaction effects for both the risk communication style and gender. The Analysis revealed a significant difference in reported levels of earthquake preparedness over time (F(1.697,303.70) = 102.58, p < 0.001; partial η2 = 0.36). However, no statistically significant interaction was found with the risk communication style (p = 0.55). Borderline significance (p = 0.04) was observed in the three-way interaction (time-intervention-gender). Gender (β = 0.19), age (β = 0.21), perceived earthquake likelihood (β = 0.14), and sense of preparedness (β = 0.28) were significant predictors in multivariate regression analysis. While consistently showing that participants exposed to empowering information reported higher earthquake preparedness, the research hypothesis was not substantiated. Recommendations for public health policy are discussed.
本研究考察了风险沟通方式（基于恐惧与基于赋权）对家庭地震准备情况的影响。利用以色列成年人口的代表性样本，对干预组和对照组进行了一项在线纵向研究。通过重复测量方差分析评估报告的准备水平变化，并考虑风险沟通方式和性别的交互作用。分析显示，随着时间的推移，报告的地震准备水平存在显著差异（F(1.697,303.70) = 102.58, p < 0.001；偏η2 = 0.36）。然而，未发现与风险沟通方式存在统计学上的显著交互作用（p = 0.55）。在三因素交互作用（时间-干预-性别）中观察到边缘显著性（p = 0.04）。在多元回归分析中，性别（β = 0.19）、年龄（β = 0.21）、感知到的地震可能性（β = 0.14）和准备意识（β = 0.28）是显著的预测因素。虽然一直表明接触赋权信息的参与者报告的地震准备水平更高，但研究假设未得到证实。文中讨论了对公共卫生政策的建议。
