Human Trafficking Research Hub (HTRH)
Human Trafficking Research Hub
A Community of Scholars, Clinicians, and Survivors
The question about the role of coercive bonding in experiences of human trafficking was the initial inquiry that led to the founding of the HTRH. The pursuit of this research question since 2017 taught the HTRH team that relationships are key to human trafficking entry, exit, prevention, and the treatment of its consequences.
The HTRH team is continuing to study the coercive mechanisms that entrap people in human trafficking. Equally, the consequences of traffickers’ coercion, the treatments that can address those consequences, and the quality and type of relationships that can prevent and disrupt human trafficking and help heal its impact are also a focus of our research.
At the HTRH, we believe that the pursuit of research is best done in an environment that develops the science about human trafficking in relation to personal, professional, and community development goals.
At a Personal Level
All our team members have a vested interest in the issue of human trafficking. To learn more about what brought each HTRH member to this work, take a look at our bios.
At a Professional Level
Students and others interested in developing their knowledge and ability to research human trafficking will find an environment in the HTRH where they can contribute to and grow with the team. To read about the philosophy of the HTRH, we invite you to take a look at an article written by John Minahan, PhD.
At a Community Level
The HTRH aims to address the mental health and psychological consequences of human trafficking through research methods that prioritize collaboration with community partners. This includes utilizing approaches like participatory action research (PAR), consensual qualitative research (CQR), and theories of liberation psychology to ensure that survivors and local organizations actively shape research questions, interpret findings, and develop interventions. To read about HTRH’s partnership with communities, we invite you to take a look at an article written by Stacy Reed-Barnes, PsyD.
