Study Summary

The current pilot project will evaluate the efficacy of adding Written Exposure Therapy (WET) to a course of repeated IV ketamine infusions in improving PTSD symptoms and maintaining symptom improvement in patients with chronic PTSD. WET is a brief, 5-session evidence-based written trauma-focused therapy without in between-session assignments, with demonstrated efficacy and low dropout rates in patients with PTSD. WET will be administered to all eligible participants; the first WET sessions will be interleaved with the last two ketamine infusions to take advantage of a window of increased neuroplasticity potentially induced by repeated ketamine infusions. WET will be administered on different days as the ketamine infusions.

Primary Outcome

Clinician Administered PTSD Scale for DSM-5 (CAPS-5), assessed at baseline (before the first infusion) and 12 weeks following the start of WET. The Clinician-Administered PTSD Scale (CAPS) is a 30-item structured diagnostic interview designed to measure frequency and intensity of PTSD symptoms. The symptoms are scored in a 0-4 Likert-type scale, total score ranging from 0 to 80, higher score indicates more symptoms
