Abstract
ObjectiveTotranslate and revise the User Version of Mobile Application Rating Scale (uMARS) , and to explore its reliability and validity.
MethodsAccording to the Brislin translation model, uMARS was translated and translated back along with two rounds of Delphi expert consultation and pre-investigation 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 1 086 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.
ResultsA 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.
ConclusionsThe 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.
