Mobile Health Intervention to Increase HIV Testing and Linkage to Care

HIV Clinical Trial

Official title: Mobile Health Intervention to Increase HIV Self Testing and Linkage to Services for High-Risk Men in China

Status Active, not recruiting

Clinical Trial Summary

This 5-year project will test an mobile health approach to improve HIV self-testing (HST) and linkage to HIV-related care among high-risk men in China. HIV-negative men who have sex with men (MSM) will be randomly assigned to an intervention group: access to WeTest-WeLink (a mobile application-based HIV testing health promotion and risk reduction program), or a control group. Participant HST and sexual risk behaviors will be evaluated at baseline and at 6, 12, and 18 months post-baseline.

Clinical Trial Description

The overarching goal of this 5-year research project is to advance the science of mobile health approaches to increase uptake of repeat HIV self-testing (HST) and linkage to HIV-related care with populations that underperform on these steps of the HIV care continuum. The proposed intervention is entitled "WeTest-WeLink" that builds on years of formative work with men who have sex with men (MSM) in China conducted by this team of investigators (R34MH106349), demonstrating promising effects from a pilot RCT and strong indication of intervention acceptability, feasibility, and cultural sensitivity. The intervention uses the "WeChat" mobile app platform, which offers multiple features built into the app that facilitate health information delivery and communication channels (e.g., capacity for private texts, group chats, video sharing, Global Positioning System (GPS), instant messaging, real-time audio and visual communication). Guided by the Information-Motivation-Behavioral (IMB) model and Minority Stress Theory, the study team will employ a user-centered design process to refine and expand app features to support repeat HST uptake, behavioral risk reduction, stigma coping strategies, and self-efficacy to link to HIV care. The study team will use an Effectiveness-Implementation Hybrid Type 1 design consisting of a three site, 2-arm randomized clinical trial (RCT) to test HST and linkage to HIV related care outcomes as well as qualitative research to examine implementation and scalability. The study team will recruit 1,800 HIV negative MSM. Participants will be allocated to the intervention (access to the WeTest-WeLink app) or control group (education about HST and passive referral to HIV care for individuals who test HIV positive). The study team will assess participants at 6, 12, and 18 months to measure intervention effects on primary outcomes of repeated use of HST (including photographic confirmation) and linkage to care for individuals who test HIV-positive. Secondary outcomes include sexual risk behaviors and use of HIV prevention services, and investigators will conduct mediation analysis to examine theoretical mechanisms of behavior change. The study team will qualitatively assess intervention-related process characteristics that enable and/or impede implementation and scalability informed by the Consolidated Framework for Implementation Research (CFIR). This project will provide the first known evidence for a mobile health approach to optimize both HIV testing and linkage to care as part of a single intervention continuum with MSM. Such findings can be crucial for optimizing the care cascade in populations that underutilize HIV services, such as MSM in China and elsewhere in the world where HIV testing and linkage to care services are sub-optimal. ;
