BACKGROUND/SIGNIFICANCE: Rainstorm floods have become a high-impact natural disaster and are expected to become more extreme shortly, seriously threatening human safety. Although the government issues timely and precise rainstorm flood warning information, citizens remain indifferent and engage in maladaptive behavior. Therefore, understanding the relationship between emergency information, psychological cognition, individual characteristics, and protective behavior is crucial for effective risk information communication and evacuation guidance.
METHOD/PROCESS: This study utilizes the protection motivation theory (PMT) and protective action decision model (PADM) to develop a structural equation model (SEM) that evaluates the factors driving both protective and non-protective behaviors of individuals to rainstorm flood disasters.
RESULT/CONCLUSION: The findings indicate that the disaster experience and emergency information received significantly shape how individuals perceive risks, their ability to manage them, and who should be accountable for the disaster. The findings further indicate that how people view their ability to handle a risk situation (perceived coping ability) and who they think is responsible for the situation (perceived attribution of responsibility) directly influence whether they will take protective behaviors. Based on these results, this study puts forward policy recommendations for emergency information release strategies to enhance citizens' willingness to adopt protective behaviors.
背景/意义：暴雨洪水已成为一种具有重大影响的自然灾害，预计短期内将变得更加极端，严重威胁人类安全。尽管政府及时发布准确的暴雨洪水预警信息，但市民仍然漠不关心，并采取适应不良的行为。因此，了解应急信息、心理认知、个体特征与保护行为之间的关系对于有效的风险信息沟通和疏散指导至关重要。
方法/过程：本研究利用保护动机理论（PMT）和保护行动决策模型（PADM）开发了一个结构方程模型（SEM），以评估驱动个体对暴雨洪水灾害采取保护和非保护行为的因素。
结果/结论：研究结果表明，灾难经历和收到的应急信息显著影响个体对风险的认知、应对风险的能力以及谁应对灾难负责。研究结果还表明，人们如何看待自己应对风险情况的能力（感知应对能力）以及他们认为谁应对该情况负责（感知责任归属）直接影响他们是否会采取保护行为。基于这些结果，本研究提出了关于应急信息发布策略的政策建议，以提高市民采取保护行为的意愿。
