Official title

Enhancing the Efficacy of Evidence-Based PTSD Treatment Via Microbiota-Directed Prebiotic Supplementation

Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

Posttraumatic stress disorder (PTSD) is a debilitating psychiatric disorder, which results from exposure to traumatic events. Veterans are more than twice as likely to suffer from PTSD compared to civilians. Current interventions for the treatment of PTSD are evidence-based psychotherapies, such as Cognitive Processing Therapy (CPT). Therefore, we plan to compare Cognitive Processing Therapy (CPT) with and without a novel prebiotic bar designed to beneficially modulate the microbiota to determine the utility of this combined approach to positively impact PTSD symptoms. We will conduct a 12-week randomized, double-blind, placebo-controlled, cross-sectional trial in veterans with PTSD. Participants will be randomized to receive CPT + prebiotic or CPT + placebo. They will be provided a supply of prebiotic or non prebiotic bars for 12 weeks. At three different time points, participants will complete questionnaires and complete questionnaires and produce a stool sample ( weeks 1,2, and 12). All participants will be recruited from the two-week in-person Intensive Outpatient Program (IOP) at the Rush Road Home Program, where they will be receiving CPT.
