Abstract

This study evaluated the usability of a mobile health application for persons with HIV (PWH) in the District of Columbia (DC) area in preparation for a pragmatic cluster randomized efficacy trial of the PositiveLinks (PL) app. Fourteen participants from the DC Cohort, a multi-site longitudinal prospective HIV cohort study, participated in Think-aloud usability testing. Participants viewed a demonstration version of the PL app and narrated their thoughts, impressions, navigation, and comments as they moved through the app functions. A second set of fourteen DC Cohort participants used the PL app for a one-month period of Beta testing to identify any bugs or glitches, then completed an in-depth interview and System Usability Survey (SUS). A majority of participants identified as male and non-Hispanic Black. Qualitative data from the Think-alouds and Beta testing interviews were audio recorded, transcribed and analyzed in Dedoose using an iterative approach. Think-aloud and Beta testing showed that users viewed the app positively and considered it to be user- friendly. Participants particularly liked the daily reminders and ability to communicate with peers with HIV and their HIV care team. Although most participants reported no dislikes, they requested more customization and more resources. The app achieved a high mean SUS score of 76 and high response rates for app features. No bugs or glitches were identified. The version of PL to be used by participants in the DC Cohort was well liked and highly usable, and participant input informed optimization of the app prior to launching the efficacy trial.

通过可用性测试和Beta测试，为华盛顿特区的艾滋病毒感染者策划了一款艾滋病毒移动健康应用程序。

本研究评估了哥伦比亚特区（DC）地区一款针对艾滋病毒感染者（PWH）的移动健康应用程序的可用性，为PositiveLinks （PL）应用程序的实用集群随机疗效试验做准备。来自DC队列（一项多站点纵向前瞻性艾滋病毒队列研究）的14名参与者参加了Think-aloud可用性测试。参与者观看了PL应用程序的演示版本，并讲述了他们在应用程序功能中移动时的想法、印象、导航和评论。第二组14名DC队列参与者使用PL应用程序进行为期一个月的Beta测试，以确定任何错误或故障，然后完成深度访谈和系统可用性调查（SUS）。大多数参与者被认为是男性和非西班牙裔黑人。来自think -aloud和Beta测试访谈的定性数据在Dedoose中使用迭代方法进行录音、转录和分析。Think-aloud和Beta测试表明，用户积极地看待这个应用程序，认为它是用户友好的。参与者特别喜欢每日提醒以及与艾滋病毒感染者及其艾滋病毒护理团队沟通的能力。尽管大多数参与者表示没有不喜欢，但他们要求更多的定制和更多的资源。该应用程序的SUS平均得分为76分，应用程序功能的响应率也很高。没有发现任何错误或故障。DC队列参与者使用的PL版本很受欢迎，可用性很高，参与者的输入在启动功效试验之前通知了应用程序的优化。
