Digital Intervention Delivered Via Street Medicine to Increase HIV and Substance Use Care Among Survivors of Sex Trafficking

Consistent with the goals of RFA-DA-25-018 Engaging Survivors of Sexual Violence and Trafficking in HIV and Substance Use Disorder Services, the objective of this R34 application is to develop and evaluate the CONNECT program for use in a sample of women with a history of sex trafficking to evaluate its feasibility, acceptability, and preliminary efficacy. CONNECT will be delivered in collaboration with the Street Medicine team, which provides health and social services directly to unhoused women in their own environment; who are at high risk for sex trafficking. CONNECT will also be administered with the support of a trained care navigator to provide 1:1 assistance in completing CONNECT and navigating referrals to substance use, HIV/STI, and mental health care. Following (ADAPT-ITT) framework and informed by a Community-Based Participatory Research approach, information from informant interviews (N = 9), focus groups (N = 30), stakeholder interviews (N = 6), and the Community Advisory Board will be leveraged to adapt the intervention. An open trial (N = 12) with a 2-month follow-up will be conducted to demonstrate program feasibility, acceptability, satisfaction, and utility of CONNECT. A randomized pilot trial (N = 60) with a 2-month follow-up will be conducted to examine whether women randomized to CONNECT, relative to control, show change in: treatment engagement outcomes for substance use (e.g., MOUD initiation, therapy for alcohol use), HIV and STI treatment/prevention services (e.g., uptake of PrEP, testing for STI), and/or mental health treatment (e.g., treatment for PTSD). Secondary outcomes of domains relating to motivation to seek treatment aligned with the theory of planned behavior (i.e., attitudes, intentions, self-efficacy, subjective norms, and stigma will be explored. Behavioral outcomes of changes in substance use outcomes (e.g., reduced substance use), HIV and STI risk behaviors, and mental health outcomes (e.g., improvements in PTSD) will also be examined. Mediators (i.e., readiness to change) and moderators (i.e., trauma history) will be examined (exploratory). To prepare for Hybrid Type I efficacy trial, exit interviews will be conducted with participants (N = 20), and practitioners (N = 9) to describe contextual factors that might influence subsequent implementation.
