背景：移动应用评级量表 (MARS) 提供了评估移动健康 (mHealth) 应用质量的可靠方法。然而，管理它需要 mHealth 和相关健康领域的培训和专业知识。 目标：本研究描述了 MARS (uMARS) 最终用户版本的开发和可靠性测试。方法：简化 MARS 并由 13 名年轻人进行试点，以创建 uMARS。随后，在参与 mHealth 应用程序随机对照试验的 164 名年轻人的第二个样本中，检查了 uMARS 的内部一致性和重测可靠性。使用 uMARS 在 1、3、和 6 个月的随访中收集应用评分。结果：uMARS 具有出色的内部一致性 (alpha = .90)，所有分量表的个体 alpha 都很高。总分和分量表在 1-2 个月和 3 个月内均具有良好的重测可靠性。结论：uMARS 是一个简单的工具，最终用户可以可靠地使用它来评估移动医疗应用程序的质量。
Background: The Mobile Application Rating Scale (MARS) provides a reliable method to assess the quality of mobile health (mHealth) apps. However, training and expertise in mHealth and the relevant health field is required to administer it.Objective: This study describes the development and reliability testing of an end-user version of the MARS (uMARS).Methods: The MARS was simplified and piloted with 13 young people to create the uMARS. The internal consistency and test-retest reliability of the uMARS was then examined in a second sample of 164 young people participating in a randomized controlled trial of a mHealth app. App ratings were collected using the uMARS at 1-, 3,- and 6-month follow up.Results: The uMARS had excellent internal consistency (alpha = .90), with high individual alphas for all subscales. The total score and subscales had good test-retest reliability over both 1-2 months and 3 months.Conclusions: The uMARS is a simple tool that can be reliably used by end-users to assess the quality of mHealth apps.
