Objective： We developed a linguistically validated Japanese version of the modRDOS-4 as an objective rating scale for dyspnea that can be used in home care and institutional settings.Methods： After receiving permission from the original developer to develop a Japanese version modRDOS-4，we developed it in accordance with general procedures used when creating linguistically validated translated versions of scale.Results：Three native Japanese translators translated the text into Japanese (forward translation), and then native English translators back-translated the Japanese draft. We and the original developer reviewed the original version and the Japanese draft for consistency with the original concept and created a provisional version. After an ethics review, an implementation survey was conducted using the provisional version. Based on the interview results, a cognitive debriefing was conducted，and we finalized the content of the Japanese version of the modRDOS-4.Discussion： We need to conduct a psychometric study on Japanese subjects in the future.
