摘要
目的对用户版移动医疗应用分级量表(uMARS)进行汉化并检验其信效度。方法根据Brislin翻译模式,对uMARS进翻译、回译、2轮德尔菲专家咨询和预调查后,形成初始量表。采用方便抽样的方法,选取2015年1月-2019年5月上线的血压管理APP为研究对象。研究小组在安卓系统的手机应用下载端及苹果系统的Apple Store,以“血压”“血压管理”等搜索词,共下载1086个APP。根据纳入与排除标准,最终纳入80个血压管理APP进行调查,由经过统一培训的2名研究者进行评分,取平均分评价量表的信效度。结果中文版uMARS经探索性因子分析共提取3个公因子,即信息、功能、用户参与度3个维度,14个条目,累计解释变异率为61.695%。量表平均内容效度指数为0.969,各条目内容效度指数为0.78~1.00。量表的Cronbach's α系数为0.890,3个维度Cronbach'sα系数分别为0.895、0.871和0.853,重测信度系数为0.967。结论中文版uMARS具有较好的信效度,适用于中国文化背景下移动医疗APP质量的评估。
Objective Totranslate and revise the User Version of Mobile Application Rating Scale(uMARS),and to explore its reliability and validity.Methods According to the Brislin translation model,uMARS was translated and translated back along with two rounds of Delphi expert consultation and preinvestigation to form the initial scale.We selected the blood management application(APP)launchedfromJanuary 2015 to May 2019 by convenience sampling as the research object.The research team downloaded 1086 APPs using the search terms"blood pressure"and"blood pressure management"on the mobile application download end of the Android system and the Apple Store of the Apple system.According to the inclusion and exclusion criteria,80 blood pressure management APPs were finally included for investigation,and two researchers with unified training graded,and the average score was used to evaluate the reliability and validity of the scale.Results A total of three exploratory factors of the Chinese version of uMARS were extracted throughexploratory factor analysis,namely three dimensions of the information,function and user participation,14 items,and the cumulative explanatory variability was 61.695%.The average content validity index of the scale was 0.969,and the content validity index of each item ranged from 0.78 to 1.00.The Cronbach's α coefficient of the scale was 0.890,and Cronbach's α coefficients of the three dimensions were 0.895,0.871 and 0.853,respectively.The retest reliability coefficient of the scale was 0.967.Conclusions The Chinese version of uMARS has good reliability and validity which is suitable for the evaluation of the quality of mobile medical APP in the context of Chinese culture.
