Testing a Peer-led Trauma-focused Intervention for Significant Others of Those With BPD

This project involves developing and piloting a peer-led intervention focused on posttraumatic stress symptoms for the family members and significant others of people with borderline personality disorder. The project involves collaborating with The Sashbear Foundation who will be delivering the trauma response program (TRP) that was developed by the investigative team to its network. In phase 1 of this project, the investigators will evaluate the first delivery of the TRP at The Sashbear Foundation and solicit feedback from peer-facilitators and recipients who consent to research participation. In phase 2 of this project, the investigators will evaluate the efficacy, acceptability, and safety of the delivery of the next two to four TRPs delivered at The Sashbear Foundation consisting of up to approximately 10 group members (maximum number of TRP recipient research participants in phase 2 is 40).
