Psychometric Properties of Disaster Preparedness Tools in Nurses: A Systematic Literature Review.

Abstract

There is no widely-recommended standardized and valid measurement tool for evaluating the disaster preparedness of nurses. This study aims to assess the psychometric properties of scales developed or adapted to evaluate the sudden-impact natural disaster preparedness of nurses. This study is a systematic literature review for the psychometric properties of disaster preparedness tools. Studies published from 2010 through June 2021 were identified from a systematic search of five databases, including Web of Science, PubMed, CINAHL, Scopus, and ProQuest. The Consensus-Based Standards for the Selection of Health Measurement Instruments (COSMIN) checklist was used for the systematic review and the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guideline for reporting. The World Health Organization's (WHO) report on the Development of a Disaster Preparedness Tool Kit for Nursing and Midwifery was used to evaluate scale contents. Six articles were identified that met the inclusion criteria. The scales generally had a multi-dimensional structure and used Likert scoring with internal consistency coefficients ranging from 0.785 to 0.97. All scales were rated sufficient in content validity, structural validity, and cross-cultural validity. One scale was rated sufficient in criterion validity while the others were rated indeterminate. One scale was rated insufficient in reliability and internal consistency while the others were rated sufficient. The findings suggest improving the psychometric properties of scales of nurses' disaster preparedness according to COSMIN, expanding their content scope, and developing new scales. The study will provide beneficial data to users and researchers regarding the need for a comprehensive assessment tool in determining the disaster preparedness of nurses.
