Summary
A new mobile app prototype, Trans Women Connected, was developed with transgender women to promote HIV prevention. User testing showed high acceptability and significant improvements in PrEP knowledge and social support, indicating mobile health interventions can be effective.
Area of Science:
- Mobile Health (mHealth)
- HIV Prevention
- Health Disparities
Background:
- Transgender women face disproportionately high HIV incidence rates in the U.S.
- Formative research with transgender women informed app design.
- Expert advisory panel of transgender women guided development.
Purpose of the Study:
- To develop and test the usability and acceptability of the Trans Women Connected mobile app prototype.
- To assess the app's potential for promoting HIV prevention among transgender women.
Main Methods:
- A 3-phase prototype development process was employed.
- Included formative research, theory-based app framework, and development of three activities: vision board, PrEP education, and interactive map.
- Usability and acceptability were tested with 16 transgender women using pre/posttests, think-aloud protocols, and open-ended questions.
Main Results:
- High acceptability reported (mean usability/likability rating of 5.9/7).
- Statistically significant increases in self-efficacy for finding LGBTQ+-friendly services, intention to seek online social support, and PrEP knowledge.
- Participants found the app attractive, useful, and all activities were perceived positively.
Conclusions:
- The Trans Women Connected mobile app prototype demonstrates strong usability and acceptability among transgender women.
- Findings support the potential of mobile health interventions for positive health behavior changes.
- Further development and an efficacy randomized trial are ongoing.
