Brief Summary

This project will assess whether a digital survivor crowdsourced intervention can increase HIV/STI/HCV testing and overdose prevention kit utilization among survivors of sex trafficking living in New York City. Survivors of sex trafficking have among the highest rates of HIV/STIs/HCV and substance use disorder (SUD), yet they face substantial barriers to care, including lack of information about care and financial and logistical constraints. In addition, there is a lack of public health messaging tailored specifically for survivors of sex trafficking to meet their needs. Citizen science approaches, such as crowdsourcing (i.e., engaging groups of individuals to address public health challenges and share solutions), are scalable, cost-effective tools that can increase HIV/SUD prevention and treatment utilization. Crowdsourcing can be used to engage survivors in developing tailored messaging to promote HIV/STI/HCV testing, overdose prevention, and treatment utilization. Complementing crowdsourcing, specimen self-collection with remote HIV/STI/HCV testing and online delivery of overdose prevention kits to survivors may also increase use of needed healthcare services. Study aims are: 1) develop crowdsourced digital messages to promote HIV/STI/HCV testing uptake and utilization of overdose prevention services for substance use among sex trafficking survivors; 2) in a randomized controlled trial, to compare the survivor-crowdsourced HIV and substance use intervention to existing public health messaging among sex trafficking survivors (n=368) in New York City; and 3) assess the contribution of multi-level factors on reach, effectiveness, adoption, implementation, and maintenance (RE-AIM) outcomes. This work will result in a digital crowdsourced intervention to increase HIV/STI/HCV testing uptake, overdose prevention kit utilization, and linkage to care among survivors of sex trafficking. This project will also result in a crowdsourcing and messaging toolkit that can be broadly distributed to public health and other agencies across the country for their use in designing messaging campaigns for survivors. Findings from this project will lay the groundwork for citizen science-developed HIV and SUD interventions for sex trafficking survivors across the US.

Outcome Measures

Primary Outcomes (2)

  • HIV/STI/HCV testing uptake

    The number of participants who ordered and returned a HIV/STI/HCV test kit from baseline to the 6-month follow-up. It is a dichotomous outcome (yes/no).

    From baseline to the 6 month follow-up

  • Overdose Prevention Kit Uptake

    The number of participants who ordered an overdose prevention kit from baseline to the 6-month follow-up. It is a dichotomous outcome (yes/no).

    From baseline to the 6 month follow-up

Secondary Outcomes (4)

  • Linkage to HIV/STI/HCV care

    From baseline to the 6-month follow-up

  • Linkage to substance use services

    From baseline to the 6 month follow-up

  • HIV/STI stigma

    Baseline, 3 months, and 6 months

  • Substance use stigma

    Baseline, 3 months, and 6 months

Study Arms (2)

Crowdsourced Messaging Intervention

EXPERIMENTAL

The digital crowdsourced intervention will be presented to participants in the intervention arm.

Behavioral: Sex Trafficking Survivor-Developed Digital Crowdsourced Intervention

Standard of Care

NO INTERVENTION

Standard informational materials about HIV/STI/HCV testing and overdose prevention currently used by Departments of Health and other health organizations will be presented to participants in the control arm.

Interventions

Survivors of sex trafficking will participate in crowdsourcing contests to create digital materials to promote HIV/STI/HCV testing and use of overdose prevention kits. Entries will be judged by community and expert judges. Top entries will be selected for the digital intervention and presented to participants in the intervention arm.
