Psychometric properties of the Farsi version of the Disaster Nursing Readiness Evaluation Index (F-DNREI)

Considering the vital role of nurses in responding to disasters, it is essential to measure their readiness with a valid and reliable tool. The present study aimed to assess the psychometric properties of the Farsi version of the Disaster Nursing Readiness Evaluation Index (F-DNREI).

This cross-sectional study was conducted between 2023 and 2024 among 200 nurses working at educational hospitals affiliated with one of the medical universities in Tehran, Iran. The Disaster Nursing Readiness Evaluation Index was translated into Persian. The face, content, and construct validity, as well as internal consistency, were analyzed.

In the exploratory factor analysis, five factors were extracted: practical skills for disaster response, adaptability to stressful situations at the disaster site, communication and cooperation skills for teamwork, emergency nursing skills, and effective coping with daily stress. Together, these factors accounted for 39.7% of the total variance. The results of the confirmatory factor analysis indicated that the extracted model fit well: CMIN/DF = 1.519, CFI = 0.889, RMSEA = 0.051. The Cronbach’s alpha and McDonald’s omega coefficients for the entire questionnaire were 0.890 and 0.891, respectively.

Given that Iran is frequently exposed to disasters, it becomes essential to assess the preparedness of Iranian nurses using a valid and reliable scale. The availability of the Farsi version of the Disaster Nursing Readiness Evaluation Index (F-DNREI), which has undergone validation and reliability testing, facilitates accurate measurement of this concept.
