Brief summary

TechStep is a three-arm, technology-based randomized controlled trial (RCT), with a stepped care approach, among high-risk HIV-negative transgender feminine, transgender masculine, and gender non-conforming youth and young adults for reducing sexual risk behaviors and increasing pre-exposure prophylaxis (PrEP) uptake. Participants are randomized into one of three conditions for a 6-month intervention: Group 1: culturally relevant theory-based text messages (Text+Step); or, Group 2: culturally relevant mobile-enhanced website (WebApp+Step); or, Group 3: informational website control condition with no theoretically based text messages or WebApp.

Detailed description

TechStep is a three-arm, technology-based randomized controlled trial (RCT), with a stepped care approach, among high-risk HIV-negative transgender feminine, transgender masculine, and gender non-conforming youth and young adults for reducing sexual risk behaviors and increasing PrEP uptake. Transgender youth and young adults are enrolled for 9 months in the RCT. During the RCT, 250 participants will be enrolled and randomized to either: (1) text messaging (n=83), (2) WebApp (n=83), or (3) an informational website control (n=83) condition. Participants will include HIV-negative youth and young adults (ages 15-24) who are self-identified transgender feminine, transgender masculine or gender non-conforming. Participants will be recruited from venues in Boston, Houston, Los Angeles, New York, and Philadelphia. There will be four data collection time points: baseline, 3-, 6-, and 9-month. Visits will be conducted in-person at the venues, online, or some combination of in person or online. An ACASI will be completed using online survey tools. An HIV test, sexually transmitted infection (STI) panel, urine screen for recent illicit drug use, and blood microsampling or dried blood spot, for those who report PrEP uptake, to verify PrEP adherence will be collected in-person at the participants local venue, or via mailed self-collection kits. Process data of each participant activity at each step of the intervention, as well as the control intervention, will be collected. The study aims to measure the effects of the information-only (Info) arm compared to a text messaging intervention (Text+Step) to a WebApp intervention (WebApp+Step) for reducing sexual risk behaviors and increasing PrEP uptake.

Interventions

BEHAVIORALText Messaging (Text+Step)

Participants receive three culturally competent, theory-based pre-written messages per day sent on a predetermined schedule. Participants who still exhibit sexual risk and do not uptake and/or adhere to PrEP at the 3-month assessment may also receive eCoaching for up to 12 weeks.

BEHAVIORALWebApp (App+Step)

Participants receive access to a culturally competent password-protected web-based application with transgender-specific resources, support, and health information. Participants who still exhibit sexual risk and do not uptake and/or adhere to PrEP at the 3-month assessment may also receive eCoaching for up to 12 weeks.

BEHAVIORALInformation/No Step

Participants in the Information/No Step intervention will receive access to a static website with information about trans health, HIV/STI information and local resources tailored for transgender persons.

Participant flow

Pre-assignment details

A confirmed negative HIV test was required to enroll in the study. Participants who used a remote enrollment option were offered at-home STI testing which included an HIV test. Participants who did not return at least the HIV test portion of the kit were subsequently and retroactively ineligible for the study, withdrawn, and not considered randomized.

Participants by arm

ArmCount
Text+Step
The TechStep Text+Step messaging intervention is a six-month technology-based culturally competent theory-based text messaging intervention that sends three automated text messages to participants daily to reduce HIV risk and increase PrEP uptake and adherence. Text Messaging (Text+Step): Participants receive three culturally competent, theory-based pre-written messages per day sent on a predetermined schedule. Participants who still exhibit sexual risk and do not uptake and/or adhere to PrEP at the 3-month assessment may also receive eCoaching for up to 12 weeks.
82
WebApp+Step
The TechStep WebApp+Step website intervention is a six-month technology-based intervention that uses peer-to-peer interaction, daily self-monitoring, and tailored content to address barriers to HIV sexual risk reduction and PrEP uptake and adherence. WebApp (App+Step): Participants receive access to a culturally competent password-protected web-based application with transgender-specific resources, support, and health information. Participants who still exhibit sexual risk and do not uptake and/or adhere to PrEP at the 3-month assessment may also receive eCoaching for up to 12 weeks.

Information
The Information/No Step intervention includes nothing more than access to a website with information about trans health, HIV/STI information and local resources tailored for transgender persons. Information/No Step: Participants in the Information/No Step intervention will receive access to a static website with information about trans health, HIV/STI information and local resources tailored for transgender persons.
