Developing a scale to measure Japanese nurses' individual readiness for deployment to disasters
Abstract
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.

A standardized, psychometrically validated instrument for assessing psychological preparedness in Japan is lacking.
“Despite its critical significance, a standardized, psychometrically validated instrument for assessing psychological preparedness in Japan is lacking.”
From Development and validation of the Japanese version of the psychological preparedness for disaster threat scale (2026) · cites this paper as [16]
The Introduction (page unavailable) says Japan lacked a scale for measuring nurses’ individual readiness for disaster deployment. That is narrower than psychological preparedness across Japan. The Abstract (page unavailable) also reports that this study developed and psychometrically evaluated a Japanese nurses’ readiness scale, so the paper does not support an unqualified claim that a validated instrument remains lacking. (LLM, conf=0.85)
Experimental — accuracy not yet measuredExisting Japanese disaster preparedness instruments predominantly focus on behavioral and material aspects and overlook psychological preparedness.
“Existing Japanese instruments tend to emphasize the behavioral and material aspects of disaster preparedness while overlooking psychological preparedness.”
From Development and validation of the Japanese version of the psychological preparedness for disaster threat scale (2026) · cites this paper as [16]
The Introduction says Japanese disaster-nursing competency models focused on knowledge and skills and paid little attention to individual readiness. It does not characterize existing Japanese instruments as predominantly behavioral and material, or specifically say they overlooked psychological preparedness. The paper also says no Japanese scale for measuring individual readiness had been developed. (LLM, conf=0.84)

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
