Emerging data suggest that few veterans are initiating prolonged exposure (PE) and cognitive processing therapy (CPT) and dropout levels are high among those who do start the therapies. The goal of this study was to use a large sample of veterans seen in routine clinical care to 1) report the percent of eligible and referred veterans who (a) initiated PE/CPT, (b) dropped out of PE/CPT, (c) were early PE/CPT dropouts, 2) examine predictors of PE/CPT initiation, and 3) examine predictors of early and late PE/CPT dropout. We extracted data from the medical records of 427 veterans who were offered PE/CPT following an intake at a Veterans Health Administration (VHA) PTSD Clinical Team. Eighty-two percent (n = 351) of veterans initiated treatment by attending Session 1 of PE/CPT; among those veterans, 38.5% (n = 135) dropped out of treatment. About one quarter of veterans who dropped out were categorized as early dropouts (dropout before Session 3). No significant predictors of initiation were identified. Age was a significant predictor of treatment dropout; younger veterans were more likely to drop out of treatment than older veterans. Therapy type was also a significant predictor of dropout; veterans receiving PE were more likely to drop out late than veterans receiving CPT. Findings demonstrate that dropout from PE/CPT is a serious problem and highlight the need for additional research that can guide the development of interventions to improve PE/CPT engagement and adherence.

After returning from an extended combat deployment to Iraq, 348 National Guard soldiers were administered the PTSD Checklist (PCL-M), and the Beck Depression Inventory II (BDI-II) followed, on average, 3 months later by structured diagnostic interviews including the Clinician-Administered PTSD Scale (CAPS) for the Diagnostic and Statistical Manual of Mental Disorders (4th ed.). There were 6.5% of the soldiers who met diagnostic criteria for posttraumatic stress disorder (PTSD) based on structured interview. The predictive validity of the PCL was examined and contrasted with the predictive validity of the BDI-II in identifying soldiers meeting CAPS diagnosis for PTSD. The best identified PCL cut scores produced between 65% and 76% false positive errors when used as the sole source for identification of enduring PTSD. Comparison of prediction between the PCL and the BDI-II in identifying PTSD suggested that both instruments may be operating through tapping generalized distress rather than specific aspects of the disorder.

OBJECTIVE Although women in the military are exposed to combat and its aftermath, little is known about whether combat as well as pre-deployment risk/protective factors differentially predict post-deployment PTSD symptoms among women compared to men. The current study assesses the influence of combat-related stressors and pre-deployment risk/protective factors on womens risk of developing PTSD symptoms following deployment relative to mens risk. METHOD Participants were 801 US National Guard Soldiers (712 men, 89 women) deployed to Iraq or Afghanistan who completed measures of potential risk/protective factors and PTSD symptoms one month before deployment (Time 1) and measures of deployment-related stressors and PTSD symptoms about 2-3 months after returning from deployment (Time 2). RESULTS Men reported greater exposure to combat situations than women, while women reported greater sexual stressors during deployment than men. Exposure to the aftermath of combat (e.g., witnessing injured/dying people) did not differ by gender. At Time 2, women reported more severe PTSD symptoms and higher rates of probable PTSD than did men. Gender remained a predictor of higher PTSD symptoms after accounting for pre-deployment symptoms, prior interpersonal victimization, and combat related stressors. Gender moderated the association between several risk factors (combat-related stressors, prior interpersonal victimization, lack of unit support and pre-deployment concerns about life/family disruptions) and post-deployment PTSD symptoms. CONCLUSIONS Elevated PTSD symptoms among female service members were not explained simply by gender differences in pre-deployment or deployment-related risk factors. Combat related stressors, prior interpersonal victimization, and pre-deployment concerns about life and family disruptions during deployment were differentially associated with greater post-deployment PTSD symptoms for women than men.

Since 2006, the Veterans Health Administration (VHA) has instituted policy changes and training programs to support system-wide implementation of two evidence-based psychotherapies (EBPs) for posttraumatic stress disorder (PTSD). To assess lessons learned from this unprecedented effort, we used PubMed and the PILOTS databases and networking with researchers to identify 32 reports on contextual influences on implementation or sustainment of EBPs for PTSD in VHA settings. Findings were initially organized using the exploration, planning, implementation, and sustainment framework (EPIS; Aarons et al. in Adm Policy Ment Health Health Serv Res 38:4–23, 2011). Results that could not be adequately captured within the EPIS framework, such as implementation outcomes and adopter beliefs about the innovation, were coded using constructs from the reach, effectiveness, adoption, implementation, maintenance (RE-AIM) framework (Glasgow et al. in Am J Public Health 89:1322–1327, 1999) and Consolidated Framework for Implementation Research (CFIR; Damschroder et al. in Implement Sci 4(1):50, 2009). We highlight key areas of progress in implementation, identify continuing challenges and research questions, and discuss implications for future efforts to promote EBPs in large health care systems.

IMPORTANCE Posttraumatic stress disorder (PTSD) is a relatively common mental health condition frequently seen, though often unrecognized, in primary care settings. Identifying and treating PTSD can greatly improve patient health and well-being. OBJECTIVE To systematically review the utility of self-report screening instruments for PTSD among primary care and high-risk populations. EVIDENCE REVIEW We searched MEDLINE and the National Center for PTSDs Published International Literature on Traumatic Stress (PILOTS) databases for articles published on screening instruments for PTSD published from January 1981 through March 2015. Study quality was rated using Quality Assessment of Diagnostic Accuracy Studies (QUADAS) criteria. STUDY SELECTION Studies of screening instruments for PTSD evaluated using gold standard structured clinical diagnostic interviews that had interview samples of at least 50 individuals. FINDINGS We identified 2522 citations, retrieved 318 for further review, and retained 23 cohort studies that evaluated 15 screening instruments for PTSD. Of the 23 studies, 15 were conducted in primary care settings in the United States (n = 14,707 were screened, n = 5374 given diagnostic interview, n = 814 had PTSD) and 8 were conducted in community settings following probable trauma exposure (ie, natural disaster, terrorism, and military deployment; n = 5302 were screened, n = 4263 given diagnostic interview, n = 393 were known to have PTSD with an additional 50 inferred by rates reported by authors). Two screens, the Primary Care PTSD Screen (PC-PTSD) and the PTSD Checklist were the best performing instruments. The 4-item PC-PTSD has a positive likelihood ratio of 6.9 (95% CI, 5.5-8.8) and a negative likelihood ratio of 0.30 (95% CI, 0.21-0.44) using the same score indicating a positive screen as used by the Department of Veterans Affairs in all of its primary care clinics. The 17-item PTSD Checklist has a positive likelihood ratio of 5.2 (95% CI, 3.6-7.5) and a negative likelihood ratio of 0.33 (95% CI, 0.29-0.37) using scores of around 40 as indicating a positive screen. Using the same score employed by primary care clinics in the Department of Veterans Affairs to indicate a positive screen, the 4-item PC-PTSD has a sensitivity of 0.69 (95% CI, 0.55-0.81), a specificity of 0.92 (95% CI, 0.86-0.95), a positive likelihood ratio of 8.49 (95% CI, 5.56-12.96) and a negative likelihood ratio of 0.34 (95% CI, 0.22-0.48). For the 17-item PTSD Checklist, scores around 40 as indicating a positive screen, have a sensitivity of 0.70 (95% CI, 0.64-0.77), a specificity of 0.90 (95% CI, 0.84-0.93), a positive likelihood ratio of 6.8 (95% CI, 4.7-9.9) and a negative likelihood ratio of 0.33 (95% CI, 0.27-0.40). CONCLUSIONS AND RELEVANCE Two screening instruments, the PC-PTSD and the PTSD Checklist, show reasonable performance characteristics for use in primary care clinics or in community settings with high-risk populations. Both are easy to administer and interpret and can readily be incorporated into a busy practice setting.

This study evaluated the impact of a course of prolonged exposure or cognitive processing therapy on mental health and medical service utilization and health care service costs provided by the Department of Veterans Affairs (VA). Data on VA health service utilization and health care costs were obtained from national VA databases for 70 veterans who completed prolonged exposure or cognitive processing therapy at a Midwestern VA medical center. Utilization of services and cost data were examined for the year before and after treatment. Results demonstrated a significant decrease in the use of individual and group psychotherapy. Direct costs associated with mental health care decreased by 39.4%. Primary care and emergency department services remained unchanged.

Evidence-based psychotherapies for PTSD are often underused. The objective of this mixed-method study was to identify organizational and clinic factors that promote high levels of reach of evidence-based psychotherapies for PTSD 10 years into their dissemination throughout the Veterans Health Administration. We conducted 96 individual interviews with staff from ten outpatient PTSD teams at nine sites that differed in reach of evidence-based psychotherapies for PTSD. Major themes associated with reach included clinic mission, clinic leader and staff engagement, clinic operations, staff perceptions, and the practice environment. Strategies to improve reach of evidence-based psychotherapies should attend to organizational and team-level factors.

Shannon M. Kehle-Forbes; Emily Hagel Campbell; Brent C. Taylor; Joel Scholten; Nina A. Sayer

Objective: To examine whether a traumatic brain injury (TBI) diagnosis was associated with increased outpatient service utilization and associated costs among Iraq and Afghanistan (Operation Enduring Freedom [OEF]/Operation Iraqi Freedom [OIF]/Operation New Dawn [OND]) War veterans with posttraumatic stress disorder (PTSD) who used Veterans Health Affairs (VHA) care in a 1-year period. Setting: N/A. Participants: OEF/OIF/OND veterans with a diagnosis of PTSD and/or TBI who utilized VHA services during fiscal year 2012 (N = 164 644). Design: Observational study using VHA administrative data. Main Measures: Outpatient VHA utilization (total and by category of care) and associated costs (total and by VA Health Economic Resource Center cost category). Results: Veterans in the comorbid PTSD/TBI group had significantly more total outpatient appointment than veterans with PTSD but no TBI. This pattern held for all categories of care except orthopedics. The comorbid TBI/PTSD group (
