Tailoring Household Disaster Preparedness Interventions to Reduce Health Disparities: Nursing Implications from Machine Learning Importance Features from the 2018-2020 FEMA National Household Survey

Tailored disaster preparedness interventions may be more effective and equitable, yet little is known about specific factors associated with disaster household preparedness for older adults and/or those with African American/Black identities. This study aims to ascertain differences in the importance features of machine learning models of household disaster preparedness for four groups to inform culturally tailored intervention recommendations for nursing practice. A machine learning model was developed and tested by combining data from the 2018, 2019, and 2020 Federal Emergency Management Agency National Household Survey. The primary outcome variable was a composite readiness score. A total of 252 variables from 15,048 participants were included. Over 10% of the sample self-identified as African American/Black and 30.3% reported being 65 years of age or older. Importance features varied regarding financial and insurance preparedness, information seeking and transportation between groups. These results reiterate the need for targeted interventions to support financial resilience and equitable resource access. Notably, older adults with Black racial identities were the only group where TV, TV news, and the Weather Channel was a priority feature for household disaster preparedness. Additionally, reliance on public transportation was most important among older adults with Black racial identities, highlighting priority needs for equity in disaster preparedness and policy.

Validation and Revision of the Household Emergency Preparedness Instrument (HEPI) by a Pilot Study in the City University of New York

OBJECTIVE

The aim of this study was to pilot test the Household Emergency Preparedness Instrument (HEPI) with a diverse sample, allowing for assessment of reliability and validity of the instrument. The HEPI is an international, all-hazards questionnaire created to measure disaster preparedness of households, which results in data that can be used to enhance health promotion/disease prevention for individuals and promote resilience for communities.

METHODS

A cross-sectional study of faculty, staff, and students (N = 284) was completed to perform factor analysis to establish the HEPI's construct validity and compare preparedness across groups.

RESULTS

The factor analysis revealed 2 dimensions of general preparedness, explaining 35% of the sample variance (Cronbach's α = 0.89): preparedness actions and planning (α = 0.86) and disaster supplies and resources (α = 0.80). This factor analysis resulted in the revision of the subscaling of HEPI questions. Consistent with previous studies, faculty/staff, older age, higher income, and those with previous disaster experience were more prepared. The mean score was 15.28 out of 40 points.

CONCLUSIONS

The HEPI is easy to administer and explains an acceptable amount of variance. The reliability was strong in this assessment, particularly for a pilot test. Construct, criterion, face, and content validity support the adequacy of the HEPI to capture essentials of household emergency preparedness.

Financial Preparedness for Emergencies: Age Patterns and Multilevel Vulnerabilities

Guided mainly by the social vulnerability perspective and life course perspective, this study examined age patterns of financial preparedness for emergencies and how they were contextualized by vulnerabilities at the individual and community levels. We matched data from the Federal Emergency Management Agency 2018 National Household Survey and 15 indicators of the Social Vulnerability Index at the county level. Two-level logistic regressions were conducted with the working sample, which included 4,623 respondents from 958 counties. The results showed that adults aged 18 to 44 were more likely than those aged 65 to 74 to set aside money for emergencies among Hispanics, those with minor children in the household, and in communities with higher levels of poverty, higher percentages of minorities, and higher percentages of no vehicles, but less likely to do so among the White and those with insurance. The findings were discussed within a multilevel layered vulnerability framework.
