Efficacy and Neural Mediators of Response to Trauma Management Therapy for PTSD

PTSD Clinical Trial

Official title: Efficacy and Neural Mediators of Response to Trauma Management Therapy for PTSD

Status Completed

Clinical Trial Summary

Social difficulties are serious and frequent complicating factors in the treatment of post-traumatic stress disorder (PTSD). To better understand how treatment of post-traumatic stress disorder impacts neural mechanisms of social cognition, the investigators are examining behavior and brain processes associated with response to Trauma Management Therapy. Understanding the behavioral and neural impact of psychotherapy may contribute to development of more effective treatments for PTSD.

Clinical Trial Description

PTSD is associated with significant interpersonal difficulties that interfere with functioning. As such, this work is intended to evaluate the empirical support for a novel treatment that fills a significant gap in the treatment options available to Veterans with PTSD who suffer with interpersonal difficulties. In this study the investigators will (i) evaluate the efficacy of Trauma Management Therapy (TMT) for treating PTSD-related interpersonal dysfunction, as well as PTSD-related fear and anxiety, and (ii) evaluate neural mediators of clinical improvements associated with TMT.

This work will provide insights into the mechanisms by which treatments may lead to improvements in social functioning, informing both the biological basis of psychotherapy and the development and refinement of alternative therapeutic interventions targeting social impairments.

Treatment seeking Veterans with PTSD will be randomized to one of two treatments: (i) Trauma Management Therapy, consisting of 12 sessions of individualized exposure therapy followed by 24 sessions of group-based social and emotional rehabilitation, or (ii) Exposure + Comparison Treatment Group consisting of 12 sessions of individualized exposure therapy followed by 24 sessions of group-based psychotherapy. Veterans enrolled in both the TMT and EXP+GRP arms will undergo functional neuroimaging as they engage in an emotional image viewing task, as well as two social interaction tasks. Neurobehavioral assessments will be made prior to and following completion of treatment. ;
