Factors affecting household disaster preparedness in South Korea.

This study examines current household disaster preparedness and identifies its predictors in South Korea. A structured online survey was administered to 1,243 participants quota-sampled by age and population from each administrative district. Based on the socio-ecological model, interpersonal factors (general characteristics, prior disaster experience, anxiety, dispositional optimism, perceived disaster risk, and disaster preparedness knowledge), institutional factor (front-line preparedness), community factor (community resilience), public policy factor (governmental preparedness), and household disaster preparedness were measured. The data were analyzed using descriptive statistics, Mann-Whitney U test, Kruskal-Wallis test, Bonferroni test, Pearson's correlation coefficients, and multiple regression. The predictors of household disaster preparedness were occupation, economic status, prior disaster experience, anxiety, disaster preparedness knowledge, front-line preparedness, and community resilience. The most potent predictor of household disaster preparedness was community resilience. Our finding that community resilience, a community factor, has a greater impact on household disaster preparedness than personal factors calls for programs that promote such resilience. Further, continuous public education and campaigns are needed to increase public awareness of household disaster preparedness and to improve the public's competency to prepare for potential disasters. This study raises the need for community programs for residents to increase household disaster preparedness knowledge and improve their competencies related to disaster response. This study is significant in highlighting the importance of community factors in improving household disaster preparedness amid the need to prepare for various types of disasters.
