In this episode, I talk with Dr. Lori Zoellner about prolonged exposure (PE) therapy, which is a highly effective, evidence-based treatment for posttraumatic stress disorder (PTSD). Dr. Zoellner is a world-renowned expert in trauma and PTSD. Her research and clinical work focus on the development, maintenance, and treatment of PTSD and she came on the show to share her expertise in treating PTSD with PE. Specifically, we talk about the rationale for PE, what changes people can expect to see with treatment, who can benefit from PE, and efforts to optimize PE treatment outcomes.
