私人家庭的防洪准备被视为综合洪水风险管理的一个重要组成部分。在过去的十年中，许多实证研究采用保护动机理论（PMT）来解释家庭层面的防洪行为。然而，大部分的研究产生了混合的结果，并不能一致地确认PMT组件之间的关系的强度和方向。基于对2,007户洪水易发区农户的调查，本研究采用结构方程模型重新审视了PMT的模型结构。与以前的研究中使用的方法相比，这种建模技术使我们能够更详细地捕获PMT组件，并全面测试它们假设的相互关系。我们的结果指出了两种不同的路线，导致两种不同的反应类型：从应对评估到保护行为的保护路线，以及从威胁评估到非保护反应的非保护路线。风险认知是没有发现的保护路线的一部分，也不是非保护性的反应证实，破坏保护的动机。在本研究中评估的6种保护性和4种非保护性应答的所有组合中，均一致观察到两种单独的途径。鉴于鼓励私人洪水适应，风险沟通措施应具体针对保护路线，避免（意外地）提供属于非保护路线的激励措施。然而，这项横断面研究无法确定这两种途径如何随着时间的推移而相互关联。需要更多的实验和纵向研究，以解决潜在的反馈效应和决策阶段的作用。
Flood preparedness of private households is regarded an essential building block of integrated flood risk management. In the past decade, numerous empirical studies have employed the protection motivation theory (PMT) to explain flood mitigation behavior at the household level. However, much of this research has produced mixed results and could not consistently confirm the strength and direction of the relationships between the PMT components. Based on a survey of 2,007 households in flood-prone areas, this study revisits the model structure of the PMT by means of structural equation modeling. Compared to the methods used in previous studies, this modeling technique allows us to capture the PMT components in greater detail and to comprehensively test their hypothesized interrelations. Our results point to two separate routes leading to two different response types: A protective route from coping appraisal to protective behavior, and a non-protective route from threat appraisal to non-protective responses. Risk perception is not found to be part of the protective route, neither are non-protective responses confirmed to undermine protection motivation. The two separate routes are observed consistently across all combinations of the six protective and four non-protective responses assessed in this study. In the light of encouraging private flood adaptation, risk communication measures should specifically target the protective route and avoid (accidentally) providing incentives that fall within the non-protective route. This cross-sectional study, however, cannot establish how the two routes interrelate over time. More experimental and longitudinal research is required to address potential feedback effects and the role of decision stages.
