Investigating the influence of information sources on flood-coping appraisal: Insights into flood mitigation behaviour

Abstract

Understanding how individuals and communities respond to flood risks is paramount for effective disaster management and community resilience. This study investigates the impact of information sources on the coping appraisal of Australian flood-prone communities (flood-coping appraisal) to gain insight into flood mitigation behaviour. Utilizing the cognitive process of Protection Motivation Theory (PMT) and integrating it with the Health Belief Model (HBM), a comprehensive framework is developed to explore the interplay between sources of information, cognitive appraisals, and coping responses. Using Partial Least Squares Structural Equation Modeling (PLS-SEM), data from a research survey are analysed to examine the relationships between latent variables within the framework. The results reveal two key components significantly affecting flood-coping appraisal: Benefit/barrier Appraisal and Social Environment. Benefit/barrier Appraisal evaluates individuals' perceptions of the cost-effectiveness of mitigation measures, their potential impacts on property appearance, and property resale value, while the Social Environment assesses individuals’ observational learning from social norms and the availability of social support. Additionally, experiences with floods inside buildings emerge as a significant factor influencing the flood-coping appraisal. The findings underscore the importance of understanding the sources of information that drive higher flood-coping appraisal for effective flood risk management and community resilience. These insights contribute to developing targeted flood risk communication strategies to promote adaptive behaviours and enhance community resilience in the face of flood hazards.
