With the number of displaced people growing worldwide and the increasing Canadian humanitarian response through resettlement, social workers will encounter resettled refugees seeking services. Providing a trauma-informed, culturally based intervention (TICBI) requires a multi-layered approach that begins with pre-planning the intervention process to foster client safety, collaboration, and empowerment. This pre-planning process involves creating a supportive environment where survivors feel safe, understood, and empowered to participate in their recovery. Planning a culturally informed intervention entails understanding how trauma affects the autonomic nervous system (ANS), including survivors’ sympathetic and parasympathetic responses. Traumatic experiences trigger the ANS to enter a state of hyperarousal or hypoarousal, leading to various physical and psychological responses that are interpreted culturally, shaping the assessment and intervention process. Therefore, planning for TICBI is necessary and begins with identifying survivors’ mindsets, which in this book are categorized into three areas: Survival, Therapeutic, and Active, Engaged mindsets, based on where survivors are in their trauma response. This approach enables social workers to reflect on the complex and individualized responses to trauma and the steps needed for the healing process. Pre-planning emphasizes the importance of cultural learning in expressing and understanding trauma. This chapter outlines the essential preparatory steps to provide a TICBI, including assessment and intervention planning.
