背景资料：尽管全球移动的健康应用程序（m Health apps）市场持续大幅增长，但大多数m Health应用程序不仅缺乏证据基础，甚至没有对基本可用性或功能进行评估。开发了用户版移动的应用程序评级量表（u MARS），以允许最终用户客观和主观地评估m Health应用程序。然而，至今还没有日本版的u MARS。目的：本研究的目的是（1）开发经过验证的日语版uMARS，（2）评估翻译版本在评估移动健康应用程序方面的可靠性和有效性。方法：原始的uMARS被改编为日本使用的四个专家使用普遍主义的跨文化方法。翻译/回译由uMARS原始版本的作者进行审查并确认。它的可靠性和有效性进行了进一步评估，作为一个前瞻性队列研究的一部分，术后患者使用一个新的mHealth app. Results：概念等效性进行了分析，并在所有子类别的原始uMARS中的所有项目都包括在日本版本。对于客观和主观质量的所有分量表，内部一致性被认为是可接受的，Cronbach α为0.75-0.85。所有分量表的重测信度也是可以接受的，组内相关系数（ICC）为0.57-0.88。收敛/发散效度和同时效度也被认为是可以接受的。结论：日本版本的uMARS进行了跨文化验证，发现与原始uMARS一样可靠。日本版的uMARS有望成为评估日本移动健康应用程序质量的标准工具。
Background: Although the global market of Mobile Health Apps (m Health apps) continues to grow dramatically, most m Health apps still not only lack evidence base but have even not been evaluated for the basic usability or functionality. The User Version of the Mobile App Rating Scale (u MARS) was developed to allow end users to assess m Health apps objectively and subjectively. However, there is no Japanese version of u MARS to date. Objective: The purpose of this study is (1) to develop a validated Japanese version of uMARS and (2) to assess the translated version's reliability and validity in evaluating mHealth apps. Methods: The original uMARS was adapted for Japanese use by four specialists using universalist cross-cultural methods. Translation/back-translation was reviewed by the author of the original version of uMARS, and confirmed. Its reliability and validity were further evaluated as part of a prospective cohort study of postoperative patients using a new mHealth app. Results: Conceptual equivalence was analyzed and all items in all subcategories of the original uMARS were included in the Japanese version. Internal consistency was deemed acceptable for all subscales of objective and subjective quality with a Cronbach's alpha of 0.75-0.85. Test-retest reliability of all subscales was also acceptable with intraclass correlation coefficients (ICCs) of 0.57-0.88. Convergent/divergent validity and concurrent validity were also considered acceptable. Conclusion: A Japanese version of uMARS was cross-culturally validated and found to be as reliable as the original uMARS. This Japanese version of uMARS is expected to become a standard tool in assessing the quality of mHealth apps in Japan.
