Trial Parameters
Brief Summary
In this study, researchers are examining the best sequence of interventions for posttraumatic stress disorder (PTSD) and tinnitus. Participants will either receive psychotherapy for PTSD first (Cognitive Processing Therapy; CPT), followed by treatment for tinnitus (Cognitive Behavioral Therapy for Tinnitus; CBT-t); or vice-versa. We also aim to identify changes in brain functioning after receiving therapy.
