The DREAM lab, in collaboration with Dr. Marie Karlsson and Dr. Melissa Zielinski, is answering a series of questions about the mechanisms that underlie the benefits of group-based exposure therapy in treating the negative sequelae of sexual violence victimization in a particularly underserved population: incarcerated women. Questions currently being investigated include: a) What are the long-term benefits of participating in this group? b) Are there mediators that explain why some participants benefit more than others, such as changes in tolerance of distressing emotions or reductions in guilt and shame? c) How do aspects of exposure therapy, such as the intensity of expressed emotion, elaboration of story elements, or responsivity of other group members, relate to symptom reductions? d) What are the profiles, psychological and demographic, of participants who benefit most from treatment compared to those who seem to benefit least?
