<p>This study aims to achieve multiple goals. Firstly, it focuses on developing a classification model for community—based support services.

摘要

This study aims to achieve multiple goals. Firstly, it focuses on developing a classification model for community—based support services. Secondly, it delves into the characteristics of families that make extensive use of community-based support services. Additionally, it investigates the mediating role of receiving disaster preparedness information and service using in the disaster impact-preparedness relationship. The data utilized in this study were sourced from the 2023 US National Household Survey. To validate our hypotheses, we employed a combination of analytical methods, including Latent Profile Analysis, multiple linear regressions, and multiple mediation analysis. Respondents aged 18–39, male, degree-educated, non-disabled, not living with elderly or dependents, with children in the household, earning over $75,000 pre-tax income, receiving disaster preparedness information, and having prior disaster experience are more likely to belong to the group with high utilization of community-based support services. Disaster impact strongly correlates with increased disaster emergency preparedness (B = 1.012; 95% CI 0.879, 1.144). However, when accounting for disaster preparedness information received and support service utilization, the direct effect drops to − 0.143 (95% CI − 0.246, − 0.040). Disaster preparedness information significantly increases the utilization of community-based support services (B = 0.354, p < 0.001). This study highlights the pivotal role of disaster preparedness information, disaster impact, and optimized utilization of community-based support services in enhancing household disaster emergency preparedness. It underscores the need to foster community engagement, support robust community resources, and implement policy initiatives aimed at strengthening these systems to bolster individual preparedness and resilience.
