The purpose of this study is to explore the effects of Narrative Exposure Therapy (NET) (Schauer, Neuner, & Elbert, 2011) on the post-traumatic symptomatology and sequelae of Latinx immigrants with complex trauma. NET was developed to meet the unique needs of individuals from non-western cultures who have experienced repeated trauma. It is an evidenced-based trauma-focused treatment characterized by the integration of emotional processing through imaginal exposure, and the documentation of past trauma through the creation of a comprehensive autobiographical narrative. The study provides an overview of NET and its empirical evidence, explores the burden of PTSD in Latinx communities, and illustrates key processes in the delivery of this treatment through a session by session analysis of how NET was implemented. Treatment considerations are demonstrated via the hybrid case example of “Ana” who serves as a vivid portrayal of a Latina psychotherapy client with PTSD consistent symptomatology stemming from both interpersonal violence and the immigration process. Ana’s composite case example is comprised of actual disguised psychotherapy cases this clinician has treated, as well as clinical examples of severe trauma found in relevant psychological literature. Demonstrating Ana’s NET course of treatment provides an avenue for describing relevant clinical issues related to the treatment of immigrant Latinx with PTSD. Using the pragmatic case study research format (Fishman, 2005), Ana’s case material is analyzed through qualitative processes and quantitative measures. It is proposed that the composite case of Ana illustrates that NET has the potential to be helpful in the treatment of Latinx immigrants suffering from PTSD related to interpersonal violence and its sequelae. This composite case study is designed to be a resource for therapists who seek to gain additional understanding of how to provide efficient and effective treatment for PTSD when working with Latinx clients. Additionally, this study provides support of NET as a promising culturally sensitive practice in evidence-based treatments for PTSD. This dissertation concludes with a discussion about future areas of study and recommendations for practice when working with this population.
