Mobile technology-based interventions show promise for conveying HIV prevention information to Latino men who have sex with men (LMSM) and Latina transgender women (LTGW); however, implementing such interventions can pose serious challenges. To understand how to adapt existing interventions for these populations, we conducted nine focus groups (N = 91 participants, 52 LMSM, 39 LTGW) in Los Angeles, California. We used a rapid assessment process to create narrative reports that we examined using thematic analysis to explore differences across sites and between LMSM and LTGW. Lessons learned: requiring smartphone use could diminish participation of poor participants; sending personalized messages on the same days and times can help participants anticipate receiving study information; working with community partners is essential for building trust; recognizing different language literacies and diverse countries of origin can improve the cultural competency of intervention materials. Addressing these challenges may enhance efforts to address the HIV prevention needs of these communities.

改善基于移动技术的艾滋病预防干预措施的策略，这些措施是针对与男性发生性关系的拉丁裔男性和拉丁裔变性女性

基于移动技术的干预措施显示了向与男性发生性关系的拉丁裔男性（LMSM）和拉丁裔跨性别女性（LTGW）传达艾滋病毒预防信息的希望；但是，实施此类干预措施可能会带来严峻的挑战。为了了解如何使这些人群适应现有的干预措施，我们在加利福尼亚州洛杉矶进行了9个焦点小组（N = 91名参与者，52名LMSM，39名LTGW）。我们使用了快速评估流程来创建叙事报告，并通过主题分析对其进行了研究，以探索站点之间以及LMSM和LTGW之间的差异。经验教训：要求使用智能手机可能会减少贫困参与者的参与；在相同的日期和时间发送个性化消息可以帮助参与者预期接收研究信息；与社区伙伴合作对于建立信任至关重要；认识到不同的语言素养和原籍国可以提高干预材料的文化能力。解决这些挑战可能会加大力度，以满足这些社区的艾滋病毒预防需求。
