Introduction: Despite the key role of Iranian nurses throughout disaster management, there is no instrument available to examine nursesâ€™ current disaster preparation levels.
Aim: The aim of this study was to develop and analyse the reliability and validity of a questionnaire on the nursesâ€™ knowledge, attitude and practice of disaster preparedness.
Materials and Methods: The scale was developed based on a comprehensive literature review and applied to 112 nurses in three public educational center affiliated to Ilam University of Medical Sciences, Ilam, Iran. Relibility was obtained using the test-retest method. Cronbachâ€™s alpha was used to verify internal consistency. Exploratory factor analysis was used to assess the validity of the questionnaire.
Results: Explanatory factor analysis using varimax rotation revealed seven main factors associated with the nursesâ€™ knowledge, attitude and practice regarding disaster preparedness. The questionnaire overall internal consistency using Cronbachâ€™s alpha was 0.785, showing acceptable internal consistency. The intraclass correlation coefficient using Test-retest method was 0.82. Total variance was 67.57%.
Conclusion: The instrument has satisfactory reliability and validity indices and can be used to measure nursesâ€™ knowledge, attitude and practice regarding disaster preparedness.
