Despite research findings that show the benefits of being prepared for increasingly tumultuous natural and coastal hazard events, studies on hazard preparedness indicate that low levels of preparedness may occur in vulnerable areas due to the uncertainty around hazard risks, expected hazard onset and impact strength, as well as associated effects. Study findings indicate that trust may impact the uncertainty and complexity faced by people dealing with unfamiliar, infrequent, and complex hazards, as well as contexts such as factors such as age, gender, prior hazard experience, and homeownership.

While studies have looked at the relationship between trust and compliance (desired protective behaviors) and the various contexts and conditions in which households prepare for natural and coastal hazards, very few studies have conceptualized trust as a tool used by households when dealing with uncertainty about coastal hazards.

The purpose of this study is to provide a household-level understanding of the influence of trust and contexts on coastal household hazard preparedness. This was accomplished through a systematic review of 52 peer-reviewed studies using rigorous search, screening, and selection processes that were guided by the PRISMA 2020 Protocol. The study produced a preliminary and expanded conceptual framework, seven (7) research propositions, and a comprehensive answer to the research question: How do contexts and trust influence household preparedness for coastal hazards?

This study provides significance to emergency management stakeholders and enhances overall preparedness efforts by developing an ordered and systematic approach tounder standing the nuances that influence household preparedness for coastal hazards. The resulting framework and research propositions can be applied by emergency preparedness stakeholders to enhance the adaptive capacities of coastal households and communities through various concerted strategies, especially in communities that are disparately affected by the effects of coastal hazards.
