This is a clinic-based, multi-site, randomized, two-arm study to compare the effectiveness of two mobile technologies designed to support PrEP adherence and continuation in cisgender and transgender men who have sex with men (MSM) and transgender women (TGW). All study participants will receive PrEP per standard of care at each of the study sites.
Participants randomized to PrEPmate will receive an interactive bidirectional text-messaging intervention that supports PrEP use through personalized communication between patients and providers. Key components include (1) weekly short message service (SMS) check-ins and a bidirectional SMS messaging platform; (2) customized daily SMS pill-taking reminders; (3) link to online PrEP Basics and videos and testimonials.
Participants randomized to Dot Diary will receive a mobile app that promotes self-management of PrEP use and sexual health. Key components include (1) a digital pill-taking and sexual diary, with pill-taking reminders; (2) sex-positive badges earned via app use; and (3) real-time feedback on protection levels afforded by PrEP. Each participant will be followed for approximately 12 months. Staff at the participating clinics will also participate in in-depth interviews to give feedback on implementation challenges and experiences in the clinic-setting, and experience working with patients using the mobile technologies.

Participants randomized to this study arm will receive the PrEPmate mHealth intervention (bi-directional text messaging with PrEP navigators/clinic staff) to support PrEP adherence and continuation.
PrEPmate is a multi-component mHealth intervention grounded in the information, motivation, behavioral skills (IMB) theory of behavior change and developed through user-centered design. PrEPmate promotes personalized communication between patients and providers through interactive weekly "check-in" messages asking participants how PrEP is going, allowing navigators to identify patients needing more help in taking PrEP, and customized daily pill-taking reminder messages. Trained PrEP navigators reach out to participants who indicate they need assistance via text or phone call and provide tailored support. Additionally, the platform supports 2-way communication between patients and PrEP navigators, including reminders for upcoming clinic visits. Participants are provided links to key information about PrEP (PrEP Basics), and video testimonials of peers taking PrEP. Messages are available in English and Spanish. PrEPmate is aimed at both patients and PrEP navigators.
Experimental: Dot Diary mobile application
Participants randomized to this study arm will download and use the Dot Diary mobile application on a personal device, to support PrEP adherence and continuation.
Device: Dot Diary
Dot Diary is a mobile phone app that integrates an electronic pill-taking and sex diary and delivers real-time feedback on PrEP protection. Using the self-management model to increase self-efficacy and patient empowerment, participants log daily PrEP pill-taking and sexual behaviors in the app, which then provides real-time feedback on the level of protection achieved from PrEP (high, medium, low), and customized instructions on doses of PrEP needed to achieve or maintain high protection. Participants can also view a weekly and monthly calendar, including visualizations of the proportion of sex acts covered by PrEP. Finally, the Dot Diary app incorporates gamification components, including an ability to earn sex-positive badges, to increase engagement. Dot Diary is aimed only at patients.
- PrEP adherence as measured by tenofovir diphosphate levels in dried blood spots [ Time Frame: DBS measured through 12 months ]PrEP adherence will be measured by tenofovir diphosphate (TFV-DP) levels in dried blood spots (DBS). Adequate adherence will be defined as having a TFV-DP ≥ 700 femtomoles/punch in DBS for daily PrEP users, which has been associated with high levels of protection in prior PrEP trials.
- Satisfaction with medical care [ Time Frame: Satisfaction measured through 12 months ]Satisfaction with medical care will be measured by the Consumer Assessment of Health Care Processes and Services (CAHPS), a critical tool for evaluating patient satisfaction and patient-centeredness of care
- Patient engagement [ Time Frame: Patient engagement measured through 12 months ]Patient engagement will be measured by the short-version Patient Activation Measure (PAM).
- PrEP continuation based on medication refills [ Time Frame: PrEP continuation measured through 12 months ]PrEP discontinuation will be defined as having a PrEP interruption of ≥30 days based on medication refill dates using blinded outcome ascertainment of electronic medical and pharmacy refill records.
- Sexual satisfaction [ Time Frame: Sexual satisfaction measured through 12 months ]Sexual satisfaction will be measured by the New Sexual Satisfaction Scale Short Version (NSSS-S), a validated 12-item questionnaire in which patients score their sexual satisfaction on five dimensions (sexual sensations, sexual presence/awareness, sexual exchange, emotional connection/closeness, and sexual activity)
- Adherence self-efficacy [ Time Frame: Adherence self-efficacy measured through 12 months ]Patient-reported adherence self-efficacy will be measured by the self-efficacy scale for PrEP use, which has been validated for PrEP use
