Japan is a disaster-prone country, and Japanese registered nurses (RN) should be evaluated for their individual readiness for unexpected dispatches. The aim of the present study was to develop and validate a scale for measuring individual readiness of Japanese RN for disasters. In our previous study in 2014, we developed a Japanese version of the Readiness Estimate and Deployability Index, which was originally developed in the USA in 1997. Considering the cultural and characteristic aspects of Japanese RN social skills, a preliminary version of the instrument was constructed in a pilot study. In the main survey, construct validity, internal consistency, and concurrent validity of the self-evaluation instrument were assessed in a sample of 964 RN, and its psychometric properties were evaluated. A six dimensional, 37 item tool called the Japanese Disaster Nursing Readiness Evaluation Index (JDNREI) was developed. The Cronbach's alpha for the scale was.93. The reliability of the six dimensions was acceptable, and the validity was supported by confirmatory factor analysis. The JDNREI, whose validity and reliability were evaluated, might enable RN to recognize and assess their level of individual readiness for future disasters.
