<![CDATA[Flood disasters pose significant risks to community health, safety, livelihoods, and social well-being, making community preparedness an essential component of disaster risk reduction. This study aimed to analyze a community preparedness model for flood disasters based on disaster knowledge, social support, and health promotion education in Reroroja Village, Magepanda District, Sikka Regency, East Nusa Tenggara, Indonesia. A quantitative analytic observational study with a cross-sectional design was conducted among 150 household heads selected using proportionate random sampling. Data were collected using structured and validated questionnaires assessing disaster knowledge, social support, health promotion education, and community preparedness. Data were analyzed using descriptive statistics and Structural Equation Modeling–Partial Least Squares (SEM-PLS). The findings demonstrated that disaster knowledge, social support, and health promotion education positively and significantly contributed to community preparedness. Health promotion education showed the strongest contribution, followed by disaster knowledge and social support. The proposed model demonstrated substantial explanatory capacity for community preparedness. These findings indicate that strengthening flood preparedness requires an integrated approach that combines improved disaster knowledge, stronger social support networks, and continuous community-based health promotion education. Such an approach can support the development of sustainable community-based disaster risk reduction strategies and strengthen the capacity and resilience of communities living in flood-prone areas.]]>
