The LifeSkills Mobile app will be evaluated in a randomized controlled trial (RCT) among 5,000 young transgender women (YTW), ages 16-29 in the United States (U.S.). Study findings will demonstrate if the intervention will reduce HIV incidence.

Official Title

Digital, Limited Interaction Efficacy Trial of LifeSkills Mobile to Reduce HIV Incidence in Young Transgender Women


LifeSkills Mobile is an mHealth intervention to promote biobehavioral HIV prevention strategies based on empowerment theory and was developed using a community-based participatory research approach. An RCT assesses the efficacy of the LifeSkills Mobile intervention in comparison to a standard of care (SOC) condition among 5,000 YTW recruited online. At baseline and every 6 months through 12-48 months (depending on when the participant enrolled), enrolled participants will complete an online survey sent via a link to their mobile phone and will be mailed an OraQuick In-Home HIV Test kit. We will also estimate the total and incremental costs of the LifeSkills Mobile intervention relative to SOC, from healthcare sector and societal perspectives.
