Open Pilot Trial of Adapted Cognitive Processing Therapy for Comorbid PTSD and Opioid Use Disorder

The goal of this open pilot trial is to learn if an adapted version of Cognitive Processing Therapy (CPT), delivered through telehealth, can treat posttraumatic stress disorder (PTSD) in adults who use syringe services programs. The main questions it aims to answer are: * Can the intervention be done in syringe services programs? * Are syringe services program clients and staff open to the intervention? * Can the intervention lower PTSD symptoms and help participants keep taking their medication for opioid use disorder (ex. Buprenorphine or methadone)? Participants will: * Attend 4-18 tele-delivered CPT sessions at the syringe services program * Complete between-session CPT practice with the support of SSP-based "coaches" * Meet with research staff monthly to complete surveys of their PTSD symptoms, drug use, and mental health
