An examination of the potential core symptoms of posttraumatic stress disorder: What is integral after removing general psychopathology & distress? J Psychiatr Res 2024; 174:46-53. [PMID: 38613942 DOI: 10.1016/j.jpsychires.2024.04.015] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/16/2023] [Revised: 03/28/2024] [Accepted: 04/03/2024] [Indexed: 04/15/2024]
Abstract
Many confirmatory factor analyses (CFA) have examined the structure of posttraumatic stress disorder (PTSD) with some suggesting increased complexity (i.e., 6+ factors), while others suggesting a more refined structure (i.e., 2-factors). These competing PTSD structures may be due to conflation of non-trauma specific symptoms that have been added overtime. However, none of these studies examined if all symptoms being examined are specific to PTSD or potentially more related to general distress and psychopathology. The current study re-evaluated the structure of PTSD using bifactor exploratory factor analysis (EFA) to identify the construct's core symptoms. Data for EFA models were taken from a sample of Veterans (N = 694) attending outpatient therapy for PTSD and were cross-validated using CFA in a sample of 297 Veterans attending residential treatment. Clinician Administered PTSD Scale for DSM-5 (CAPS-5) at pre-treatment was used across sample. Factor analyses resulted in a 2-factor, bifactor model comprised of eight total items. Model fit was robust, RMSEA = 0 [0.000, 0.036]; robust CFI = 1; robust TLI = 1.017. The bifactor analytic approach captured what might be the core structure of PTSD, which were pathognomonic symptoms of PTSD (Factor one). A distinct second factor related to depression was also found. In identifying this structure, the model eliminates redundancies and lesser performing items and differentiates depressive reactions as potentially distinct and separate. Overall, these findings may assist in future research of PTSD by determining the unique elements of the construct within a veteran sample versus associated features, general psychological distress, and comorbid psychopathology.

Impact of PTSD treatment on postconcussive symptoms in veterans: A comparison of sertraline, prolonged exposure, and their combination. J Psychiatr Res 2024; 173:64-70. [PMID: 38503135 DOI: 10.1016/j.jpsychires.2024.03.011] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/30/2023] [Revised: 02/29/2024] [Accepted: 03/07/2024] [Indexed: 03/21/2024]
Abstract
Many Veterans who served in Iraq and Afghanistan struggle with posttraumatic stress disorder (PTSD) and the effects of traumatic brain injuries (TBI). Some people with a history of TBI report a constellation of somatic, cognitive, and emotional complaints that are often referred to as postconcussive symptoms (PCS). Research suggests these symptoms may not be specific to TBI. This study examined the impact of PTSD treatment on PCS in combat Veterans seeking treatment for PTSD. As part of a larger randomized control trial, 198 Operation Iraqi Freedom, Operation Enduring Freedom, Operation New Dawn (OIF/OEF/OND) Veterans with PTSD received Prolonged Exposure Therapy, sertraline, or the combination. Potential deployment related TBI, PCS, PTSD and depression symptoms were assessed throughout treatment. Linear mixed models were used to predict PCS change over time across the full sample and treatment arms, and the association of change in PTSD and depression symptoms on PCS was also examined. Patterns of change for the full sample and the subsample of those who reported a head injury were examined. Results showed that PCS decreased with treatment. There were no significant differences across treatments. No significant differences were found in the pattern of symptom change based on TBI screening status. Shifts in PCS were predicted by change PTSD and depression. Results suggest that PCS reduced with PTSD treatment in this population and are related to shift in depression and PTSD severity, further supporting that reported PCS symptoms may be better understood as non-specific symptoms.

Abstract
PURPOSE OF REVIEW This review discusses the current and projected landscape of psychedelic-assisted therapy (PAT), with a focus on clinical, legal, and implementation considerations in Department of Defense (DoD) and Department of Veterans Affairs (VA) healthcare systems. RECENT FINDINGS 3,4-Methylenedioxymethamphetamine (MDMA)- and psilocybin-assisted therapy have shown promising outcomes in efficacy, safety, tolerability, and durability for PTSD and depression, respectively. MDMA-assisted therapy is already approved by the Food and Drug Administration (FDA) on an Expanded Access ("compassionate use") basis for PTSD, with full approval projected for 2024. Psilocybin-assisted therapy is projected to be FDA-approved for depression soon thereafter. Other psychedelics are in earlier stages of development. The VA is currently conducting PAT clinical trials. Although there are clear legal pathways for the VA and DoD to conduct PAT trials, a number of implementation barriers exist, such as the very high number of clinical hours necessary to treat each patient, resource requirements to support treatment infrastructure, military-specific considerations, and the high level of evidence necessary for PAT to be recommended in clinical practice guidelines. Ongoing considerations are whether and how PAT will be made available to VA and DoD beneficiaries, feasibility and cost-effectiveness, and ethical safeguards that must be implemented to prioritize access to PAT given the likelihood of extremely limited initial availability. However, with imminent FDA approval of PATs and considerable national interest in these treatments, DoD and VA policymakers must be prepared with clearly delineated policies and plans for how these healthcare systems will approach PAT.

Associations of health care staff burnout with negative health and organizational outcomes in the U.S. military health system. Soc Sci Med 2023; 330:116049. [PMID: 37418990 DOI: 10.1016/j.socscimed.2023.116049] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/17/2022] [Revised: 06/09/2023] [Accepted: 06/26/2023] [Indexed: 07/09/2023]
Abstract
RATIONALE Burnout is a personal and occupational phenomenon that has been associated with negative physical and psychological outcomes in medical staff. Additionally, there are implications for healthcare organizations, as those staff who are burned out are more likely to have lower productivity or leave the organization. As with the Covid-19 pandemic, future national emergencies and potentially large-scale conflicts will require similar and likely even larger scale responses from the U.S. Military Health System, thus it is important to understand burnout in this population so that the readiness of the staff and the military can remain at a high level. OBJECTIVE This assessment was designed to examine levels of burnout among United States Military Health System (MHS) staff working at Army installations and the factors that influence the development of burnout. METHODS Anonymous data was collected from 13,558 active-duty U.S. Soldiers and civilian MHS employees. Burnout was measured using the Copenhagen Burnout Inventory and the Mini-Z. RESULTS Results showed nearly half of staff who responded (48%) reported being burned out, an increase since last measured in 2019 (31%). Factors related to increased burnout included concerns about work/life balance and workload, low job satisfaction and feeling disconnected from others. Burnout was associated with increases in adverse physical and behavioral health (BH) outcomes. CONCLUSIONS Results indicate that burnout is a common problem across MHS Army staff and is related to significant adverse health consequences for the individual and reduced retention of staff for the organization. These findings highlight the need to address burnout through policies that standardize health care delivery policies and practices, providing support to leadership to promote a healthy workplace, and individual support to those who experience burnout.

Calibrating the Alcohol Use Disorders Identification Test-Consumption (AUDIT-C) for detecting alcohol-related problems among Canadian, UK and US soldiers: cross-sectional pre-deployment and post-deployment survey results.

Abstract
OBJECTIVES Excessive alcohol use can bring about adverse health and work-related consequences in civilian and military populations. Screening for excessive drinking can help identify individuals at risk for alcohol-related problems who may require clinical interventions. The brief validated measures of alcohol use such as the Alcohol Use Disorders Identification Test (AUDIT), or abbreviated AUDIT-Consumption (AUDIT-C), are often included in military deployment screening and epidemiologic surveys, but appropriate cut-points must be used to effectively identify individuals at risk. Although the conventional AUDIT-C cut-points ≥4 for men and ≥3 for women are commonly used, recent validation studies of veterans and civilians recommend higher cut-points to minimise misclassification and overestimation of alcohol-related problems. This study aims to ascertain optimal AUDIT-C cut-points for detecting alcohol-related problems among serving Canadian, UK and US soldiers. DESIGN Cross-sectional pre/post-deployment survey data were used. SETTINGS Comprised Army locations in Canada and UK, and selected US Army units. PARTICIPANTS Included soldiers in each of the above-mentioned settings. OUTCOME MEASURES Soldiers' AUDIT scores for hazardous and harmful alcohol use or high levels of alcohol problems served as a benchmark against which optimal sex-specific AUDIT-C cut-points were assessed. RESULTS Across the three-nation samples, AUDIT-C cut-points of ≥6/7 for men and ≥5/6 for women performed well in detecting hazardous and harmful alcohol use and provided comparable prevalence estimates to AUDIT scores ≥8 for men and ≥7 for women. The AUDIT-C cut-point ≥8/9 for both men and women performed fair-to-good when benchmarked against AUDIT ≥16, although inflated AUDIT-C-derived prevalence estimates and low positive predictive values were observed. CONCLUSION This multi-national study provides valuable information regarding appropriate AUDIT-C cut-points for detecting hazardous and harmful alcohol use, and high levels of alcohol problems among soldiers. Such information can be useful for population surveillance, pre-deployment/post-deployment screening of military personnel, and clinical practice.

Abstract
Background: Soldiers are resilient to just war events, such as killing enemy combatants and life-threatening experiences, but these same soldiers appear to struggle with unjust war events, such as killing a noncombatant or being unable to help civilian women and children in need. This study is the first to examine how just and unjust war experiences are associated with clinical health service outcomes. Methods: Two samples of soldiers in different stages of readjustment from deployment were drawn from a longitudinal, survey-based study of a US Army brigade. Measures included items related to combat events, mental health utilization, perceived mental health need, PTSD, depression, and functional impairment. Results: After controlling for other kinds of combat events, just war events (i.e., life-threatening events and killing enemy combatants) predicted outcomes in soldiers who are less than three months post-deployment, but only predicted 2 of 26 outcomes in soldiers one year post deployment. In contrast, unjust war events were found to be robust predictors of short-term and long-term outcomes related to mental health need and utilization, even after controlling for exposure to other combat events. Conclusions: The results extend previous longitudinal research that suggests that exposure to unjust war events carry a heavier long-term mental health burden than other types of events. Additionally, Soldiers exposed to unjust war events had an unmet need for care one year post deployment that was not directly tied to PTSD or depression. The results question the emphasis on life-threat within mental health pathogenesis models.

Abstract
BACKGROUND For decades confirmatory factor analysis (CFA) has been the preeminent method to study the underlying structure of posttraumatic stress disorder (PTSD); however, methodological limitations of CFA have led to the emergence of other analytic approaches. In particular, network analysis has become a gold standard to investigate the structure and relationships between PTSD symptoms. A key methodological limitation, however, which has significant clinical implications, is the lack of data on the potential impact of item order effects on the conclusions reached through network analyses. METHODS The current study, involving a large sample (N = 5055) of active duty army soldiers following deployment to Iraq, assessed the vulnerability of network analyses and prevalence rate to item order effects. This was done by comparing symptom networks of the DSM-IV PTSD checklist items to these same items distributed in random order. Half of the participants rated their symptoms on traditionally ordered items and half the participants rated the same items, but in random order and interspersed between items from other validated scales. Differences in prevalence rate and network composition were examined. RESULTS The prevalence rate differed between the ordered and random item samples. Network analyses using the ordered survey closely replicated the conclusions reached in the existing network analyses literature. However, in the random item survey, network composition differed considerably. CONCLUSION Order effects appear to have a significant impact on conclusions reached from PTSD network analysis. Prevalence rates were also impacted by order effects. These findings have important diagnostic and clinical treatment implications.

Pathways to mental health care in active military populations across the Five-Eyes nations: An integrated perspective. Clin Psychol Rev 2021; 91:102100.

Abstract
Military service is associated with increased risk of mental health problems. Previous reviews have pointed to under-utilization of mental health services in military populations. Building on the most recent systematic review, our narrative, critical review takes a complementary approach and considers research across the Five-Eyes nations from the past six years to update and broaden the discussion on pathways to mental healthcare in military populations. We find that at a broad population level, there is improvement in several indicators of mental health care access, with greater gains in initial engagement, time to first treatment contact, and subjective satisfaction with care, and smaller gains in objective indicators of adequacy of care. Among individual-level barriers to care-seeking, there is progress in improving recognition of need for care and reducing stigma concerns. Among organizational-level barriers, there are advances in availability of services and cultural acceptance of care-seeking. Other barriers, such as concerns around confidentiality, career impact, and deployability persist, however, and may account for some remaining unmet need. To address these barriers, new initiatives that are more evidence-based, theoretically-driven, and culturally-sensitive, are therefore needed, and must be rigorously evaluated to ensure they bring about additional improvements in pathways to care.

Abstract
IMPORTANCE The definition of posttraumatic stress disorder (PTSD) changed markedly between the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition (DSM-IV) and DSM-5, creating challenges for studies and in medical settings spanning this transition. OBJECTIVE To evaluate the ability to compare and assess PTSD, based on DSM-IV and DSM-5 criteria, using PTSD Checklists (PCLs). DESIGN, SETTING, AND PARTICIPANTS This diagnostic study was conducted with survey data collected in October 2019, from the Millennium Cohort Study, a population-based US military cohort study. The population for the present study was restricted to a subset of initial web responders of the 2019 survey cycle, randomly assigned to 1 of 4 survey groups. EXPOSURES Each group received the DSM-IV and DSM-5 PCL (PCL-Civilian [PCL-C] version and PCL for DSM-5 [PCL-5]). PCL instruments were counterbalanced to control for order effects. MAIN OUTCOMES AND MEASURES Survey data were used to assess PTSD (using the PCL-C and PCL-5), major depressive disorder (using the Patient Health Questionnaire), generalized anxiety (using the Generalized Anxiety Disorder scale), and problem drinking (using the Patient Health Questionnaire). Demographic and military characteristics included age, sex, race/ethnicity, marital status, education, service branch, pay grade, enrollment panel, and military service status. RESULTS Among the 1921 participants (mean [SD] age, 50.1 [12.5] years), 1358 (70.7%) were men, 1638 (85.3%) were non-Hispanic White individuals, 1440 (75.0%) were married, and 1190 (61.9%) had at least a bachelor's degree; 295 (15.4%) had probable PTSD according to DSM-IV criteria with PCL-C compared with 286 (14.9%) using DSM-5 criteria with PCL-5 (κ = 0.77). There was substantial agreement between PCLs for probable PTSD based on DSM-IV criteria (295 [15.4%] with PCL-C; 316 [16.4%] with PCL-5; κ = 0.80) and DSM-5 criteria (286 [14.9%] with PCL-5; 258 [13.4%] with PCL-C; κ = 0.77). Estimated PTSD sum scores showed excellent agreement with observed scores. Using an established crosswalk, PCL-5 sum scores estimated with the PCL-C were similar to observed PCL-5 scores. Of the 17 corresponding items between the 2 instruments, 16 had substantial agreement. Appending 2 additional PCL-C items to the PCL-5 did not significantly alter estimates. The PCL-C and PCL-5 had nearly identical associations with comorbid conditions. CONCLUSIONS AND RELEVANCE The findings of this diagnostic study suggest that PTSD can be successfully assessed and compared over time with either PCL instrument in veteran and military populations.

Association of Combat Experiences With Suicide Attempts Among Active-Duty US Service Members. JAMA Netw Open 2021; 4:e2036065.

Abstract
Importance There is uncertainty about the role that military deployment experiences play in suicide-related outcomes. Most previous research has defined combat experiences broadly, and a limited number of cross-sectional studies have examined the association between specific combat exposure (eg, killing) and suicide-related outcomes. Objective To prospectively examine combat exposures associated with suicide attempts among active-duty US service members while accounting for demographic, military-specific, and mental health factors. Design, Setting, and Participants This cohort study analyzed data from the Millennium Cohort Study, an ongoing prospective longitudinal study of US service members from all military branches. Participants were enrolled in 4 phases from July 1, 2001, to April 4, 2013, and completed a self-administered survey at enrollment and every 3 to 5 years thereafter. The population for the present study was restricted to active-duty service members from the first 4 enrollment phases who deployed in support of the wars in Iraq and Afghanistan. Questionnaire data were linked with medical encounter data through September 30, 2015. Data analyses were conducted from January 10, 2017, to December 14, 2020. Exposures Combat exposure was examined in 3 ways (any combat experience, overall combat severity, and 13 individual combat experiences) using a 13-item self-reported combat measure. Main Outcomes and Measures Suicide attempts were identified from military electronic hospitalization and ambulatory medical encounter data using the International Classification of Diseases, Ninth Revision codes. Results Among 57 841 participants, 44 062 were men (76.2%) and 42 095 were non-Hispanic White individuals (72.8%), and the mean (SD) age was 26.9 (5.3) years. During a mean (SD) follow-up period of 5.6 (4.0) years, 235 participants had a suicide attempt (0.4%). Combat exposure, defined broadly, was not associated with suicide attempts in Cox proportional hazards time-to-event regression models after adjustments for demographic and military-specific factors; high combat severity and certain individual combat experiences were associated with an increased risk for suicide attempts. However, these associations were mostly accounted for by mental disorders, especially posttraumatic stress disorder. After adjustment for mental disorders, combat experiences with significant association with suicide attempts included being attacked or ambushed (hazard ratio [HR], 1.55; 95% CI, 1.16-2.06), seeing dead bodies or human remains (HR, 1.34; 95% CI, 1.01-1.78), and being directly responsible for the death of a noncombatant (HR, 1.81; 95% CI, 1.04-3.16). Conclusions and Relevance This study suggests that deployed service members who experience high levels of combat or are exposed to certain types of combat experiences (involving unexpected events or those that challenge moral or ethical norms) may be at an increased risk of a suicide attempt, either directly or mediated through a mental disorder.

Abstract
Objective: Studies examining posttraumatic growth (PTG) rely on surveys evaluating PTG in relation to prior traumatic experiences, resulting in psychometric problems due to the linkage of the dependent and independent variables. Few studies have assessed PTG following combat deployment while also controlling for mental health problems.Method: Longitudinal data on PTG, combat experience, and mental health were examined among U.S. Millennium Cohort Study deployers (n = 8732). Scores from a short-form (SF) version of the PTG inventory assessing current-state beliefs (C-PTGI-SF) independent of any predictor variables were assessed at time 1 (T1), before deployment, and change in scores were assessed approximately 3 years later after deployment at time 2 (T2). All participants screened negative for posttraumatic stress disorder (PTSD) and depression at T1.Results: Combat deployment severity was associated with a worsening of C-PTGI-SF scores at T2 among participants with moderate C-PTGI-SF scores at T1. A positive screen for comorbid PTSD/depression was associated with a worsening of C-PTGI-SF scores at T2 among participants with moderate or high C-PTGI-SF scores at T1. At T2, a strong inverse correlation was found between C-PTGI-SF scores and PTSD (r = -0.38) and depression (-0.41). Only 5% of participants who screened positive for a mental health problem at T2 (23/517) also experienced positive growth.Conclusions: These results challenge the clinical utility of the PTG construct. While PTG may be a useful framework for supporting trauma recovery on an individual basis, PTG does not appear to be distinct and independent from the negative psychological impact of traumatic experiences.

Abstract
Objective: Rates of behavioral health disorders and potential protective factors in U.S. Special Operations Forces (SOF) have not been well studied, including differences between Operators and Support personnel, despite very high levels of combat exposure in these military personnel. The present study examined the prevalence of endorsed behavioral health problems and protective factors within a large sample of SOF personnel. Method: Anonymized data from 16,284 active duty SOF Service members from the 2016 Preservation of the Force and Family (POTFF) needs survey were analyzed. Results: Overall, the prevalence of PTSD (7.6%), depression (8.4%), alcohol misuse (12.8%), and nicotine use (28%) were comparable or lower than reported in conventional military populations. There were significant differences between Operators and Support personnel in a number of demographic and service-related variables. Operators also endorsed more direct combat exposure and scored higher on resilience and social support, and reported better quality and quantity of sleep. There were no significant group differences in rates of PTSD and depression, except lower odds (adjusted OR = 0.81) for alcohol problems in Support personnel (11.6%) compared to Operators (14.0%), p <.001, 95% CI [0.72, 0.91]. Conclusions: SOF personnel experience considerably higher exposure to combat deployments than conventional forces, yet the data from this study showed comparable or lower levels of behavioral health conditions. Although Operators were somewhat more likely than Support personnel to experience alcohol problems, they showed enhanced resilience, social support, and sleep health. Alcohol misuse is one potential target for preventive health efforts.

Abstract
BACKGROUND The current study examines the unique and interactive effects of posttraumatic stress disorder (PTSD) symptoms and days using alcohol, opioids, and marijuana on PTSD symptoms, suicidal ideation, and suicidal behavior up to 1 year, later in a high-risk sample of military personnel not active in mental health treatment. METHODS Current and former military personnel at risk for suicide (N = 545; M age = 31.91 years, standard deviation = 7.27; 88.2% male) completed self-report measures of PTSD symptoms, past 30 days heavy alcohol use, opioid use, marijuana use, and current suicidal ideation via telephone at baseline and 1, 3, 6, and 12 months later. PTSD symptoms and the substance use variables (and relevant covariates) were entered as predictors of changes in PTSD symptoms, the likelihood of suicidal ideation, suicidal ideation severity, and the likelihood of suicidal behavior during the 11-month follow-up period. RESULTS PTSD symptoms predicted PTSD symptoms 1 month later. PTSD symptoms and marijuana use predicted the likelihood of suicidal ideation 1 month later and suicidal behavior during the 11-month follow-up period. The interaction between PTSD symptoms and marijuana use significantly predicted increased PTSD symptoms over time and suicidal behavior. At high, but not low levels of PTSD symptoms, more days using marijuana predicted increased PTSD symptoms over time and the likelihood of suicidal behavior. CONCLUSIONS Results suggest marijuana, especially for military personnel experiencing elevated PTSD symptoms may negatively impact suicidal thoughts and behavior. These results are relevant to suggestions that medical marijuana could be used in treating or augmenting treatment for PTSD.

Abstract
Large health care systems are seeking to reduce variation in care delivery and improve outcomes. This column describes the U.S. Army health care system's transformation to a service line management model and the impact on behavioral health care between 2013 and 2017. An evaluation found a promising association between the service line model and greater use of standard outpatient clinical programs, more frequent engagement of patients with serious conditions, and less use of inpatient services. The observational nature of these preliminary findings does not permit causal inferences; however, the service line model may help health care systems reduce variation between geographically distinct care delivery locations and improve performance.

Abstract
Importance Meta-analyses of treatments for posttraumatic stress disorder (PTSD) suggest that trauma-focused psychotherapies produce greater benefits than antidepressant medications alone. Objective To determine the relative efficacy of prolonged exposure therapy plus placebo, prolonged exposure therapy plus sertraline hydrochloride, and sertraline plus enhanced medication management in the treatment of PTSD. Design, Setting, and Participants The Prolonged Exposure and Sertraline Trial was a randomized, multisite, 24-week clinical trial conducted at the Veterans Affairs Ann Arbor Healthcare System, Veterans Affairs San Diego Healthcare System, Ralph H. Johnson Veterans Affairs Medical Center, and Massachusetts General Hospital Home Base Veterans Program between January 26, 2012, and May 9, 2016. Participants and clinicians were blinded to pill condition, and outcome evaluators were blinded to assignment. Participants completed assessments at weeks 0 (intake), 6, 12, 24, and 52 (follow-up). Participants (N = 223) were service members or veterans of the Iraq and/or Afghanistan wars with combat-related PTSD and significant impairment (Clinician-Administered PTSD Scale score, ≥50) of at least 3 months' duration. Analyses were on an intent-to-treat basis. Intervention Participants completed up to thirteen 90-minute sessions of prolonged exposure therapy by week 24. Sertraline dosage was titrated during a 10-week period and continued until week 24; medication management was manualized. Main Outcomes and Measures The primary outcome was symptom severity of PTSD in the past month as assessed by the Clinician-Administered PTSD Scale score at week 24. Results Of 223 randomized participants, 149 completed the study at 24 weeks, and 207 (180 men and 27 women; mean [SD] age, 34.5 [8.3 years]) were included in the intent-to-treat analysis. Modified intent-to-treat analysis using a mixed model of repeated measures showed that PTSD symptoms decreased significantly during the 24 weeks (sertraline plus enhanced medication management, 33.8 points; prolonged exposure therapy plus sertraline, 32.7 points; and prolonged exposure therapy plus placebo, 29.4 points; β,-9.39; 95% CI, -11.62 to -7.16; P < .001); however, slopes did not differ by treatment group (prolonged exposure therapy plus placebo group, -9.39; sertraline plus enhanced medication management group, -10.37; and prolonged exposure therapy plus sertraline group, -9.99; P = .81). Conclusions and Relevance No difference in change in PTSD symptoms or symptom severity at 24 weeks was found between sertraline plus enhanced medication management, prolonged exposure therapy plus placebo, and prolonged exposure therapy plus sertraline. Trial Registration ClinicalTrials.gov Identifier: NCT01524133.

Postconcussive symptoms (PCS) following combat-related traumatic brain injury (TBI) in Veterans with posttraumatic stress disorder (PTSD): Influence of TBI, PTSD, and depression on symptoms measured by the Neurobehavioral Symptom Inventory (NSI). J Psychiatr Res 2018; 102:8-13.

Abstract
Mild traumatic brain injury (mTBI) is commonly reported in recent combat Veterans. While the majority resolve, some Veterans develop postconcussive symptoms (PCS). Previous research suggests these symptoms are not specific to head injury and are often associated with psychiatric symptoms. The current study examines the relative contributions of posttraumatic stress, depressive symptoms, and TBI on postconcussive symptoms, and explores whether the relationship remains after controlling for symptom overlap. Two hundred eighteen combat Veterans from Operation Iraqi Freedom (OIF), Operation Enduring Freedom (OEF), and Operation New Dawn (OND) provided the data for this study as part of a baseline evaluation for inclusion into larger treatment study for posttraumatic stress disorder (PTSD). Participants completed the Brief Traumatic Brain Injury Screen (BTBIS), Neurobehavioral Symptom Inventory (NSI), PTSD Checklist-Stressor Version (PCL-S), Beck Depression Inventory-II (BDI-II). Significant differences in NSI total score between individuals with and without history of TBI were not found. A series of regression analyses demonstrated that Depression and PTSD were significant predictors of NSI score even after removal of NSI symptoms that overlap with PTSD or depression. TBI status was also a significant predictor of PCS in most models, but its relative contribution was much smaller than that of depression and PTSD. Within PTSD symptoms, hyperarousal cluster was a significant predictor of NSI scores. Findings demonstrate that depression and PTSD are related to PCS beyond similarities in construct. Further, within a primarily PTSD treatment-seeking population, these psychiatric symptoms appear to be a stronger contributor than TBI.

Measuring Aggregated and Specific Combat Exposures: Associations Between Combat Exposure Measures and Posttraumatic Stress Disorder, Depression, and Alcohol-Related Problems. J Trauma Stress 2018; 31:296-306. [PMID: 29603393 DOI: 10.1002/jts.22273] [Citation(s) in RCA: 33] [Impact Index Per Article: 5.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/30/2017] [Revised: 12/27/2017] [Accepted: 01/05/2018] [Indexed: 11/09/2022]
Abstract
Research has shown combat exposure to be associated with negative mental health outcomes. Different combat exposure measures are not composed of the same combat experiences, and few combat exposure measures have been directly compared to another measure. Furthermore, research about the unique associations between specific combat experiences and mental health is lacking. We investigated associations between new-onset posttraumatic stress disorder (PTSD), new-onset depression, and alcohol-related problems and two commonly used measures of combat among a sample of 20,719 recently deployed U.S. military personnel. A 13-item measure assessed both direct and indirect combat exposures, and a 5-item measure assessed only indirect exposures. Both combat measures were associated with all outcomes in the same direction (e.g., PTSD, odds ratio [OR] = 2.97 vs. 4.01; depression, OR = 2.03 vs. 2.42; alcohol-related problems, OR = 1.41 vs. 1.62, respectively, for the 5- and 13-item measures). The 13-item measure had a stronger association with some outcomes, particularly PTSD. Each specific item had significant bivariate associations with all outcomes, ORs = 1.43-4.92. After adjusting for other combat exposures, items assessing witnessing abuse, feeling in danger, and knowing someone injured or killed remained associated with all outcomes, ORs = 1.18-2.72. After this adjustment, several items had unexpected protective associations with some mental health outcomes. Results indicated these two combat exposure measures were approximately equally effective for determining risk for negative mental health outcomes in a deployed population, despite having different content. Additional research is needed to replicate and understand how specific combat exposures affect health.

Abstract
BACKGROUND Posttraumatic stress disorder (PTSD) can have long-term and far-reaching impacts on health and social and occupational functioning. This study examined factors associated with persistent PTSD among U.S. service members and veterans. METHODS Using baseline and follow-up (2001-2013) questionnaire data collected approximately every 3 years from the Millennium Cohort Study, multivariable logistic regression was conducted to determine factors associated with persistent PTSD. Participants included those who screened positive for PTSD using the PTSD Checklist-Civilian Version at baseline (N = 2409). Participants were classified as having remitted or persistent PTSD based on screening negative or positive, respectively, at follow-up. RESULTS Almost half of participants (N = 1132; 47%) met criteria for persistent PTSD at the first follow-up; of those, 804 (71%) also screened positive for PTSD at the second follow-up. Multiple factors were independently associated with persistent PTSD in an adjusted model at the first follow-up, including older age, deployment with high combat exposure, enlisted rank, initial PTSD severity, depression, history of physical assault, disabling injury/illness, and somatic symptoms. Among those with persistent PTSD at the first follow-up, additional factors of less sleep, separation from the military, and lack of social support were associated with persistent PTSD at the second follow-up. CONCLUSIONS Combat experiences and PTSD severity were the most salient risk factors for persistent PTSD. Comorbid conditions, including injury/illness, somatic symptoms, and sleep problems, also played a significant role and should be addressed during treatment. The high percentage of participants with persistent PTSD supports the need for more comprehensive and accessible treatment, especially after separation from the military.

Abstract
BACKGROUND Current clinical practice guidelines (CPGs) for posttraumatic stress disorder (PTSD) offer contradictory recommendations regarding use of medications or psychotherapy as first-line treatment. Direct head-to-head comparisons are lacking. METHODS Systemic review of Medline, EMBASE, PILOTS, Cochrane Central Register of Controlled Trials, PsycINFO, and Global Health Library was conducted without language restrictions. Randomized clinical trials ≥8 weeks in duration using structured clinical interview-based outcome measures, active-control conditions (e.g. supportive psychotherapy), and intent-to-treat analysis were selected for analyses. Independent review, data abstraction, and bias assessment were performed using standardized processes. Study outcomes were grouped around conventional follow-up time periods (3, 6, and 9 months). Combined effect sizes were computed using meta-analyses for medication versus control, medication pre-/posttreatment, psychotherapy versus control, and psychotherapy pre-/posttreatment. RESULTS Effect sizes for trauma-focused psychotherapies (TFPs) versus active control conditions were greater than medications versus placebo and other psychotherapies versus active controls. TFPs resulted in greater sustained benefit over time than medications. Sertraline, venlafaxine, and nefazodone outperformed other medications, although potential for methodological biases were high. Improvement following paroxetine and fluoxetine treatment was small. Venlafaxine and stress inoculation training (SIT) demonstrated large initial effects that decreased over time. Bupropion, citalopram, divalproex, mirtazapine, tiagabine, and topiramate failed to differentiate from placebo. Aripiprazole, divalproex, guanfacine, and olanzapine failed to differentiate from placebo when combined with an antidepressant. CONCLUSIONS Study findings support use of TFPs over nontrauma-focused psychotherapy or medication as first-line interventions. Second-line interventions include SIT, and potentially sertraline or venlafaxine, rather than entire classes of medication, such as SSRIs. Future revisions of CPGs should prioritize studies that utilize active controls over waitlist or treatment-as-usual conditions. Direct head-to-head trials of TFPs versus sertraline or venlafaxine are needed.

Abstract
OBJECTIVE The study sought to identify the extent to which posttraumatic stress disorder (PTSD) diagnoses are recorded in the electronic health record (EHR) in Army behavioral health clinics and to assess clinicians' reasons for not recording them and treatment factors associated with recording or not recording the diagnosis. METHODS A total of 543 Army mental health providers completed the anonymous, Web-based survey. Clinicians reported clinical data for 399 service member patients, of whom 110 (28%) had a reported PTSD diagnosis. Data were weighted to account for sampling design and nonresponses. RESULTS Of those given a diagnosis of PTSD by their clinician, 59% were reported to have the diagnosis recorded in the EHR, and 41% did not. The most common reason for not recording was reducing stigma or protecting the service member's career prospects. Psychiatrists were more likely than psychologists or social workers to record the diagnosis. CONCLUSIONS Findings indicate that for many patients presenting with PTSD in Army behavioral health clinics at the time of the survey (2010), clinicians did not record a PTSD diagnosis in the EHR, often in an effort to reduce stigma. This pattern may exist for other diagnoses. Recent Army policy has provided guidance to clinicians on diagnostic recording practice. An important implication concerns the reliance on coded diagnoses in PTSD surveillance efforts by the U.S. Department of Defense (DoD). The problem of underestimated prevalence rates may be further compounded by overly narrow DoD surveillance definitions of PTSD.

Abstract
The cumulative strain of 14 years of war on service members, veterans, and their families, together with continuing global threats and the unique stresses of military service, are likely to be felt for years to come. Scientific as well as political factors have influenced how the military has addressed the mental health needs resulting from these wars. Two important differences between mental health care delivered during the Iraq and Afghanistan wars and previous wars are the degree to which research has directly informed care and the consolidated management of services. The U.S. Army Medical Command implemented programmatic changes to ensure delivery of high-quality standardized mental health services, including centralized workload management; consolidation of psychiatry, psychology, psychiatric nursing, and social work services under integrated behavioral health departments; creation of satellite mental health clinics embedded within brigade work areas; incorporation of mental health providers into primary care; routine mental health screening throughout soldiers' careers; standardization of clinical outcome measures; and improved services for family members. This transformation has been accompanied by reduction in psychiatric hospitalizations and improved continuity of care. Challenges remain, however, including continued underutilization of services by those most in need, problems with treatment of substance use disorders, overuse of opioid medications, concerns with the structure of care for chronic postdeployment (including postconcussion) symptoms, and ongoing questions concerning the causes of historically high suicide rates, efficacy of resilience training initiatives, and research priorities. It is critical to ensure that remaining gaps are addressed and that knowledge gained during these wars is retained and further evolved.

Abstract
BACKGROUND Inconsistent findings between studies of gender differences in mental health outcomes in military samples have left open questions of differential prevalence in posttraumatic stress disorder (PTSD) among all United States Army soldiers and in differential psychosocial and comorbid risk and protective factor profiles and their association with receipt of treatment. METHODS This study assesses the prevalence and risk factors of screening positive for PTSD for men and women based on two large, population-based Army samples obtained as part of the 2005 and 2008 U.S. Department of Defense Surveys of Health Related Behaviors among Active Duty Military Personnel. RESULTS The study showed that overall rates of PTSD, as measured by several cutoffs of the PTSD Checklist, are similar between active duty men and women, with rates increasing in both men and women between the two study time points. Depression and problem alcohol use were strongly associated with a positive PTSD screen in both genders, and combat exposure was significantly associated with a positive PTSD screen in men. Overall, active duty men and women who met criteria for PTSD were equally likely to receive mental health counseling or treatment, though gender differences in treatment receipt varied by age, race, social support (presence of spouse at duty station), history of sexual abuse, illness, depression, alcohol use, and combat exposure. CONCLUSIONS The study demonstrates that the prevalence of PTSD as well as the overall utilization of mental health services is similar for active duty men compared with women. However, there are significant gender differences in predictors of positive PTSD screens and receipt of PTSD treatment.

Abstract
IMPORTANCE Posttraumatic stress disorder (PTSD) is a disabling psychiatric disorder common among military personnel and veterans. First-line psychotherapies most often recommended for PTSD consist mainly of "trauma-focused" psychotherapies that involve focusing on details of the trauma or associated cognitive and emotional effects. OBJECTIVE To examine the effectiveness of psychotherapies for PTSD in military and veteran populations. EVIDENCE REVIEW PubMed, PsycINFO, and PILOTS were searched for randomized clinical trials (RCTs) of individual and group psychotherapies for PTSD in military personnel and veterans, published from January 1980 to March 1, 2015. We also searched reference lists of articles, selected reviews, and meta-analyses. Of 891 publications initially identified, 36 were included. FINDINGS Two trauma-focused therapies, cognitive processing therapy (CPT) and prolonged exposure, have been the most frequently studied psychotherapies for military-related PTSD. Five RCTs of CPT (that included 481 patients) and 4 RCTs of prolonged exposure (that included 402 patients) met inclusion criteria. Focusing on intent-to-treat outcomes, within-group posttreatment effect sizes for CPT and prolonged exposure were large (Cohen d range, 0.78-1.10). CPT and prolonged exposure also outperformed waitlist and treatment-as-usual control conditions. Forty-nine percent to 70% of participants receiving CPT and prolonged exposure attained clinically meaningful symptom improvement (defined as a 10- to 12-point decrease in interviewer-assessed or self-reported symptoms). However, mean posttreatment scores for CPT and prolonged exposure remained at or above clinical criteria for PTSD, and approximately two-thirds of patients receiving CPT or prolonged exposure retained their PTSD diagnosis after treatment (range, 60%-72%). CPT and prolonged exposure were marginally superior compared with non-trauma-focused psychotherapy comparison conditions. CONCLUSIONS AND RELEVANCE In military and veteran populations, trials of the first-line trauma-focused interventions CPT and prolonged exposure have shown clinically meaningful improvements for many patients with PTSD. However, nonresponse rates have been high, many patients continue to have symptoms, and trauma-focused interventions show marginally superior results compared with active control conditions. There is a need for improvement in existing PTSD treatments and for development and testing of novel evidence-based treatments, both trauma-focused and non-trauma-focused.

Abstract
OBJECTIVE To characterize the indirect associations of combat exposure with post-deployment physical symptoms through shared associations with post-traumatic stress disorder (PTSD), depression and insomnia symptoms. METHODS Surveys were administered to a sample of U.S. soldiers (N = 587) three months after a 15-month deployment to Iraq. A multiple indirect effects model was used to characterize direct and indirect associations between combat exposure and physical symptoms. RESULTS Despite a zero-order correlation between combat exposure and physical symptoms, the multiple indirect effects analysis did not provide evidence of a direct association between these variables. Evidence for a significant indirect association of combat exposure and physical symptoms was observed through PTSD, depression, and insomnia symptoms. In fact, 92% of the total effect of combat exposure on physical symptoms scores was indirect. These findings were evident even after adjusting for the physical injury and relevant demographics. CONCLUSION This is the first empirical study to suggest that PTSD, depression and insomnia collectively and independently contribute to the association between combat exposure and post-deployment physical symptoms. Limitations, future research directions, and potential policy implications are discussed.
