In this workshop for frontline health and social service providers, participants will explore how experiences of trauma and stigma can impact service users’ health and well-being as well as access to health and social services. Through discussion and interactive activities, participants will explore the principles of trauma- and violence-informed care (TVIC), and learn to employ this approach within their practice to challenge the stigma associated with STBBIs, sexuality, and substance use. Participants will gain practical tools and skills to integrate TVIC into their interactions with service users, and into the policies and practices of their organizations in order to contribute to safer and more inclusive sexual health, harm reduction and STBBI-related services. The turnkey workshop resources, including a facilitation manual, a participant workbook and the presentation slides, can help you facilitate a training session in your community.
