Evaluation of the Trans Women Connected Mobile App for Changes in Sexual Health-related Behavior Among Transgender Women

The study is a 2-arm cluster randomized controlled trial to be conducted with 450 trans women to assess the effectiveness of the Trans Women Connected mobile app. Those in the treatment arm will be provided with the Trans Women Connected app, to be downloaded to their own device, and asked to use it during a month period. Those in the control arm will be asked to download a general health app and use it during a month period. Participants will complete brief online surveys at baseline, immediately following the app-use period (1-month post baseline), and at 3- and 6-months following baseline. The baseline and follow-up assessments will collect data on demographic characteristics, measures related to our primary and secondary outcomes, and psychosocial measures. The primary outcome measures are self-reported sexually transmitted infection (STI)/HIV testing and sex without a condom, with secondary measures including sexual risk behaviors, health care visits, perceived social support/connectedness, pre-exposure prophylaxis (PrEP) use, self-efficacy in negotiation/communication, and comfort with gender identity and appearance. In addition, process data, such as forum content, and usage data will be collected and analyzed.
