Translation, reliability, and validity of Japanese version of the Respiratory Distress Observation Scale.

Dyspnea is a common, distressing symptom of cardiopulmonary and neuromuscular diseases and is defined as "a subjective experience of breathing discomfort that consists of qualitatively distinct sensations that vary in intensity." However, Japanese intensive care units (ICUs) do not routine...

To translate the RDOS, we conducted a prospective observational study in a 12-bed ICU of a universal hospital that included 42 healthcare professionals, 10 expert panels, and 128 ventilated patients. The English version was translated into Japanese, and several cross-sectional web-based questionnaires were administered to the healthcare professionals.

Inter-rater reliability was evaluated using Cohen's weighted kappa coefficient. Criterion validity was ascertained based on the correlation between RDOS and the dyspnea visual analog scale. The area under the receiver operating characteristic curve analysis was used to evaluate the ability of the RDOS to identify patients with self-reported dyspnea. The average content validity index at the scale level was 0.95. Data from the 128 patients were collected and analyzed. Cohen's weighted kappa coefficient and the correlation coefficient between the two scales were 0.76 and 0.443 (95% confidence intervals 0.70-0.82 and 0.23-0.62), respectively. For predicting self-reported dyspnea, the area under the receiver operating characteristic curve was 0.81 (95% confidence interval 0.67-0.97). The optimal cutoff used was 1, with a sensitivity and specificity of 0.89 and 0.61, respectively.
