年轻的跨性别女性（YTW）是降低艾滋病相关风险的关键人群，但针对她们需求所开发的干预措施却寥寥无几。兼具有效性和广泛覆盖潜力的移动健康干预措施是降低年轻跨性别女性艾滋病风险的一种有前景的策略。
本研究旨在将一种有效的基于小组的干预措施改编为一款移动应用程序——生活技能项目（Project LifeSkills），以降低年轻跨性别女性的艾滋病风险，并测试其可接受性和可用性。
在专家咨询小组的建议以及在以用户为中心的设计环节中收集的年轻跨性别女性的反馈基础上，将基于小组的干预措施改编为一款移动应用程序——生活技能移动版（LifeSkills Mobile）。然后，使用出声思考协议以及事后汇报访谈、屏幕活动记录，并通过研究后系统可用性问卷（PSSUQ）和健康信息技术可用性评估量表（Health - ITUES）对该应用程序的测试版进行可用性评估。
年轻跨性别女性（n = 8；年龄：平均24岁，标准差3岁；少数族裔：7/8，88%）在设计环节中对应用程序原型提供了反馈，然后在可用性试验中对该应用程序的测试版进行了测试（n = 10；年龄：平均24岁，标准差3岁；少数族裔：8/10，80%）。可用性评分（Health - ITUES：平均4.59，标准差0.86；量表范围：1 - 5）以及满意度和可及性评分（PSSUQ：平均4.64，标准差0.90；量表范围1 - 5）都处于良好到优秀的范围。未发现功能性漏洞，所有移动活动都按预期部署。可用性访谈中参与者的反馈表明干预内容在目标人群中具有很好的显著性。参与者关于进一步提高应用程序参与度的建议包括添加动画、添加音频以及减少文字量。
我们得出结论，生活技能移动版应用程序是一款非常可用且具有吸引力的用于年轻跨性别女性艾滋病预防的移动应用程序。
Young transgender women (YTW) are a key population for HIV-related risk reduction, yet very few interventions have been developed to meet their needs. Mobile health interventions with the potential for both efficacy and wide reach are a promising strategy to reduce HIV risk among YTW. This study aims to adapt an efficacious group-based intervention to a mobile app, Project LifeSkills, to reduce HIV risk among YTW, and to test its acceptability and usability. The group-based intervention was adapted to a mobile app, LifeSkills Mobile, with input from an expert advisory group and feedback from YTW collected during user-centered design sessions. A beta version of the app was then tested in a usability evaluation using a think-aloud protocol with debriefing interviews, recordings of screen activity, and assessments of usability via the Post-Study System Usability Questionnaire (PSSUQ) and the Health Information Technology Usability Evaluation Scale (Health-ITUES). YTW (n=8; age: mean 24 years, SD 3 years; racial or ethnic minority: 7/8, 88%) provided feedback on the app prototype in design sessions and then tested a beta version of the app in a usability trial (n=10; age: mean 24 years, SD 3 years; racial or ethnic minority: 8/10, 80%). Both usability ratings (Health-ITUES: mean 4.59, SD 0.86; scale range: 1-5) and ratings for satisfaction and accessibility (PSSUQ: mean 4.64, SD 0.90; scale range 1-5) were in the good to excellent range. No functional bugs were identified, and all mobile activities were deployed as expected. Participant feedback from the usability interviews indicated very good salience of the intervention content among the focal population. Participants’ suggestions to further increase app engagement included adding animation, adding audio, and reducing the amount text. We conclude that the LifeSkills Mobile app is a highly usable and engaging mobile app for HIV prevention among YTW.
