Background Despite large-scale dissemination and implementation efforts of evidence-based psychotherapy to veterans from Operation Enduring/Iraqi Freedom (OEF/OIF), little is known regarding the factors that contribute to the successful completion of these treatments in this high-risk population. The present study investigated predictors of treatment completion during a standardized exposure-based psychotherapy for PTSD. Methods Ninety-two OEF/OIF combat veterans enrolled in a randomized controlled trial for an eight session exposure-based psychotherapy for PTSD. All participants completed structured clinical interviews and several background and symptom questionnaires. Of the initial 92 participants, 28% of the sample (n = 26) discontinued treatment prior to completion of the trial. Results Predictors of discontinuation of treatment were assessed with a hierarchical logistic regression. Disability status was positively associated with treatment discontinuation, and postdeployment social support was negatively associated with discontinuation. In contrast to previous findings, other factors, such as age and PTSD symptomatology, were not identified as significant predictors. Conclusions The present study suggested that disability status at the start of treatment increases the risk for treatment discontinuation whereas increased social support buffers against discontinuation. Together, these findings highlight the importance of increased assessment and early intervention when these factors are present to potentially reduce treatment discontinuation and improve treatment outcomes in OEF/OIF veterans with PTSD. © Published 2013.

Background Physiological reactivity to trauma-related cues is a primary symptom of PTSD and can be assessed objectively using script-driven imagery paradigms. However, subjective self-reported symptom measures are the most common outcome indices utilized in PTSD treatment trials and clinic settings. We examined physiological reactivity during a short trauma imagery task as an objective index of response to PTSD treatment, optimized for use in routine clinical care settings. Methods Participants were 35 male combat veterans receiving prolonged exposure (PE) therapy in a Veterans Affairs outpatient clinic. In addition to traditional subjective self-reported and clinician-rated symptom measures, patients also completed a script-driven imagery task in which heart rate (HR) and skin conductance (SC) were recorded at three assessment points across treatment. We examined changes in subjective symptom measures and objective trauma-specific physiological reactivity over the course of PE, and investigated the association between pretreatment physiological reactivity and treatment response. Results Patients who completed PE showed significantly diminished HR and SC reactivity to trauma imagery across therapy. Additionally, individuals showing greater trauma-specific HR reactivity at pretreatment showed greater reductions in subjectively reported PTSD symptoms at posttreatment. Conclusions Findings support the utility of physiological reactivity during trauma imagery as an objective outcome measure that has the potential to be incorporated into evidence-based PTSD treatment in routine clinical settings, or prospective studies related to the individualization of care at pretreatment. © 2015 Wiley Periodicals, Inc.
