Post-Traumatic Stress Disorder (PTSD) Clinical Trials

Intrusive traumatic memories frequently trigger severe distress and psychological disorders such as post-traumatic stress disorder (PTSD). Traditional therapies require explicit trauma recall, which often causes severe patient distress and may lead to treatment avoidance. To address this, our study introduces a less aversive intervention that combines unconscious visual processing with bilateral eye movements to reduce intrusive traumatic memories. Utilizing a randomized, three-arm design, we will compare standardized trauma-related images, patient-provided images, and neutral images, all paired with bilateral eye movements. We plan to recruit participants who have experienced severe trauma and report at least 5 intrusive memories per week, with a target final sample of 40 participants per arm. The primary outcome is the frequency of intrusive memories. Secondary and additional outcomes include PTSD severity, as measured by the Clinician-Administered PTSD Scale for DSM-5 (CAPS-5), the PTSD Checklist for DSM-5 (PCL-5), and the Impact of Event Scale (IES), as well as depression, anxiety, borderline symptoms, functional improvement, subjective intervention distress, and dropout rates.
