Abstract

Objectives This study evaluated the validity and reliability of the Persian version of the Disaster Resilience Measuring Tool (DRMT-C19). Methods The research was a methodological, psychometric study. Standard translation processes were performed. Face validity and content validity were determined along with construct and convergent validity. To determine the final version of the questionnaire, 483 health care rescuers were selected using a consecutive sampling method. Other resilience-related questionnaires were used to assess concurrent validity. All quantitative data analyses were conducted using SPSS 22 and Jamovi 2.3.28 software. Results The content validity and reliability were indicated using Scale's Content Validity Ratio (S-CVR) = 0.92 and Scale's Content Validity Index (S-CVI) = 0.93. The comprehensiveness of the measurement tool = 0.875%. Cronbach's α = 0.89 and the test re-test reliability using interclass correlation coefficients (ICC) = 0.68 to 0.92. Exploratory factor analysis determined 4 factors which accounted for more than 58.54% of the variance among the items. Confirmatory factor analysis determined 12 factors. The concurrent validity between the DRMT-C19 and the Connor-Davidson Resilience Scale (CD-RISC) was r = 0.604 (P ≤ 0.0001). Conclusions The DRMT-C19 has satisfactory psychometric properties and is a valid, reliable, and valuable tool for assessing resilience against disasters in Iran's Persian-speaking health care rescuers. © The Author(s), 2024.
