BACKGROUND
Young transgender women are a key population to reach 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 young transgender women.
OBJECTIVE
The purpose of this study was to adapt an efficacious group-based intervention to mobile app, Project LifeSkills, to reduce HIV risk among young transgender women, and then test its acceptability and usability.
METHODS
The group-based intervention was adapted to a mobile app, LifeSkills Mobile, with input from an expert advisory group and feedback from young transgender women 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 de-briefing interview, recording of screen activity, and assessment of usability on the Post Study System Usability Questionnaire (PSSUQ) and the Health Information Technology Usability Evaluation Scale (Health-ITUES).
RESULTS
Young transgender women (N=8; mean age 24.1, 87.5% racial/ethnic minority), provided feedback on the app prototype in design sessions and then tested a beta version of the app in a usability trial (N=10; mean age 24.5, 80% racial/ethnic minority). Usability ratings were in the good to excellent range (mean Health-ITUES=4.59, SD=0.86, scale range 1-5) as were ratings for satisfaction/accessibility (mean PSSUQ=4.64, DS=0.90, scale range 1-5). There were no functional bugs identified and all mobile activities deployed as expected. Participant feedback in usability interviews indicates very good salience of the intervention content for the target population. Participant suggestions to further increase app engagement include: animation, audio, and reduced text.
CONCLUSIONS
We conclude that LifeSkills Mobile app is a highly usable and engaging mobile app for HIV prevention among young transgender women.
