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 ( = 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.
