Risk Factors of Obesity in Veterans of Recent Conflicts: Need for Diabetes Prevention.

PURPOSE OF REVIEW: To identify factors associated with obesity in veterans of the recent, Operation Enduring Freedom (OEF), Operation Iraqi Freedom (OIF), and Operation New Dawn (OND) war conflicts. RECENT FINDINGS: Over 44% OEF/OIF/OND veterans are obese (BMI > 30 kg/m2), which exceeds the national obesity prevalence rate of 39% in people younger than 45. Obesity increases morbidity, risk for type 2 diabetes (T2D), and mortality as well as decreases quality of life. A scoping review method was used to identify factors associated with obesity in young veterans. Military exposures, such as multiple deployments and exposure to combat, contribute to challenges in re-integration to civilian life in all veterans. Factors that contribute to increased risk for obesity include changes in eating patterns/eating disorders, changes in physical activity, physical disability, and psychological comorbidity. These conditions can contribute to a rapid weight gain trajectory, changes in metabolism, and obesity. Young veterans face considerable challenges related to obesity risk. Further research is needed to better understand young veterans' experiences and health needs in order to adapt or expand existing programs and improve access, engagement, and metabolic outcomes in this vulnerable population.

Functional Brain Alterations Associated With Cognitive Control in Blast-Related Mild Traumatic Brain Injury.

OBJECTIVES: Research on the cognitive sequelae of mild traumatic brain injury (mTBI) suggests that, despite generally rapid recovery, difficulties may persist in the domain of cognitive control. The goal of this study was to examine whether individuals with chronic blast-related mTBI show behavioral or neural alterations associated with cognitive control. METHODS: We collected event-related functional magnetic resonance imaging (fMRI) data during a flanker task in 17 individuals with blast-related mTBI and 16 individuals with blast-exposure without TBI (control). RESULTS: Groups did not significantly differ in behavioral measures of cognitive control. Relative to the control group, the mTBI group showed greater deactivation of regions associated with the default mode network during the processing of errors. Additionally, error processing in the mTBI group was associated with enhanced negative coupling between the default mode network and the dorsal anterior cingulate cortex as well as the dorsolateral prefrontal cortex, regions of the salience and central executive networks that are associated with cognitive control. CONCLUSIONS: These results suggest that deactivation of default mode network regions and associated enhancements of connectivity with cognitive control regions may act as a compensatory mechanism for successful cognitive control task performance in mTBI.

Complexity of the Relationships of Pain, Posttraumatic Stress, and Depression in Combat-Injured Populations: An Integrative Review to Inform Evidence-Based Practice.

BACKGROUND: Understanding the complex interrelationships between combat injuries, physical health, and mental health symptoms is critical to addressing the healthcare needs of wounded military personnel and veterans. The relationship between injury characteristics, pain, posttraumatic stress disorder (PTSD), and depression among combat-injured military personnel is unique to modern conflicts and understudied in the nursing literature. AIM: This integrative review synthesizes clinical presentations and relationships of combat injury, PTSD, depression, and pain in Operation Enduring Freedom (OEF) and Operation Iraqi Freedom (OIF) United States military service members and veterans. METHODS: A literature search was conducted using relative key terms across databases to identify peer-reviewed publications between 2001 and 2016 that examined health outcomes of combat-injured persons in OEF and OIF. The quality of evidence was evaluated and results synthesized to examine the association of combat injury as a risk factor for PTSD, the relationship of PTSD and depression pre- and postinjury, and pain management throughout care. RESULTS: Twenty-two articles were included in this review. Greater injury and pain severity poses risks for developing PTSD following combat injury, while early symptom management lessens risks for PTSD. Depression appears to be both a contributing risk factor to postinjury PTSD, as well as a comorbidity. LINKING EVIDENCE TO ACTION: Findings demonstrate a compelling need for improvements in standardized assessment of pain and mental health symptoms across transitions in care. This integrative review informs nurse researchers and providers of the clinical characteristics of pain, PTSD, and depression following combat injury and offers implications for future research promoting optimal surveillance of symptoms.

Deployment and Adverse Pregnancy Outcomes: Primary Findings and Methodological Considerations.

Objective To characterize the pregnancy outcomes of women Operation Enduring Freedom/Operation Iraqi Freedom (OEF/OIF) Veterans including prevalence of preterm delivery, low birth weight, and macrosomia, and to highlight methodological limitations that can impact findings. Methods A retrospective cohort study was conducted starting in 2014 analyzing data from the 2009 to 2011 National Health Study for a New Generation of US Veterans, which sampled Veterans deployed and not deployed to OIF/OEF. All pregnancies resulting in a live birth were included, and categorized as occurring among non-deployers, before deployment, during deployment, or after deployment. Outcomes included preterm birth, low birth weight, and macrosomia. The association of deployment with selected outcomes was estimated using separate general estimating equations to account for lack of outcome independence among women contributing multiple pregnancies. Adjustment variables included maternal age at outcome, and race/ethnicity. Results There were 2276 live births (191 preterm births, 153 low birth weight infants, and 272 macrosomic infants). Compared with pregnancies before deployment, pregnancies among non-deployers and those after deployment appeared to have greater risk of preterm birth [non-deployers: odds ratio (OR) = 2.16, 95 % confidence interval (CI) 1.25, 3.72; after deployment: OR = 1.90, 95 % CI 0.90, 4.02]. A similar pattern was observed for low birth weight. No association of deployment with macrosomia was detected. Discussion Compared with non-deployers, those who eventually deploy appear to have better pregnancy outcomes prior to deployment, but this advantage is no longer apparent after deployment. Non-deployers may not be an appropriate reference group to study the putative health impacts of deployment on pregnancy outcomes.

White matter abnormalities are associated with chronic postconcussion symptoms in blast-related mild traumatic brain injury.

Blast-related mild traumatic brain injury (mTBI) is a common injury among Iraq and Afghanistan military veterans due to the frequent use of improvised explosive devices. A significant minority of individuals with mTBI report chronic postconcussion symptoms (PCS), which include physical, emotional, and cognitive complaints. However, chronic PCS are nonspecific and are also associated with mental health disorders such as posttraumatic stress disorder (PTSD). Identifying the mechanisms that contribute to chronic PCS is particularly challenging in blast-related mTBI, where the incidence of comorbid PTSD is high. In this study, we examined whether blast-related mTBI is associated with diffuse white matter changes, and whether these neural changes are associated with chronic PCS. Ninety Operation Enduring Freedom/Operation Iraqi Freedom (OEF/OIF) veterans were assigned to one of three groups including a blast-exposed no--TBI group, a blast-related mTBI without loss of consciousness (LOC) group (mTBI--LOC), and a blast-related mTBI with LOC group (mTBI + LOC). PCS were measured with the Rivermead Postconcussion Questionnaire. Results showed that participants in the mTBI + LOC group had more spatially heterogeneous white matter abnormalities than those in the no--TBI group. These white matter abnormalities were significantly associated with physical PCS severity even after accounting for PTSD symptoms, but not with cognitive or emotional PCS severity. A mediation analysis revealed that mTBI + LOC significantly influenced physical PCS severity through its effect on white matter integrity. These results suggest that white matter abnormalities are associated with chronic PCS independent of PTSD symptom severity and that these abnormalities are an important mechanism explaining the relationship between mTBI and chronic physical PCS.

History of loss of consciousness with mild traumatic brain injury affects PTSD symptom presentation in treatment-seeking Iraq/Afghanistan veterans.

OBJECTIVE: This study was conducted (1) to examine differences in post-traumatic stress disorder (PTSD) symptoms, perceived quality-of-life (QoL) and post-concussive symptoms (PCS) among veterans who experienced deployment-related mild traumatic brain injuries (mTBIs) with or without loss of consciousness (LOC) and (2) to test the additive role of PCS on QOL. DESIGN: Two hundred and twelve Iraq/Afghanistan veterans who were admitted to a residential programme for PTSD were assessed shortly following intake. A MANCOVA was conducted to examine QoL, PTSD symptom domains and PCS across the No LOC and LOC groups. Multivariate regression models were conducted to examine whether prevalence of PCS might be uniquely linked with veterans' QoL (physical, psychological and social). RESULTS: When controlling for combat exposure (CE), LOC status was uniquely linked with avoidance symptomatology, Psychological QoL and PCS; LOC status was not significantly linked with other domains of PTSD or QoL. When controlling for CE and PTSD, PCS was similarly linked with QoL in the psychological domain, but not Physical or Social QoL. CONCLUSION/IMPLICATIONS: LOC associated with a mTBI may contribute to behavioural avoidance and poorer psychological well-being among veterans seeking treatment for PTSD. In addition, PCS associated with mTBI may diminish Psychological QoL for veterans seeking treatment for PTSD.

Posttraumatic Psychological Symptoms are Associated with Reduced Inhibitory Control, not General Executive Dysfunction.

Although there is mounting evidence that greater PTSD symptoms are associated with reduced executive functioning, it is not fully understood whether this association is more global or specific to certain executive function subdomains, such as inhibitory control. We investigated the generality of the association between PTSD symptoms and executive function by administering a broad battery of sensitive executive functioning tasks to a cohort of returning Operation Enduring Freedom/Operation Iraqi Freedom Veterans with varying PTSD symptoms. Only tasks related to inhibitory control explained significant variance in PTSD symptoms as well as symptoms of depression, while measures of working memory, measures of switching, and measures simultaneously assessing multiple executive function subdomains did not. Notably, the two inhibitory control measures that showed the highest correlation with PTSD and depressive symptoms, measures of response inhibition and distractor suppression, explained independent variance. These findings suggest that greater posttraumatic psychological symptoms are not associated with a general decline in executive functioning but rather are more specifically related to stopping automatic responses and resisting internal and external distractions.

A Qualitative Study of Potential Suicide Risk Factors Among Operation Iraqi Freedom/Operation Enduring Freedom Soldiers Returning to the Continental United States (CONUS).

OBJECTIVE: A qualitative study among Operation Enduring Freedom/Operation Iraqi Freedom (OEF/OIF) Soldiers was conducted to explore potential constructs underlying suicide according to the interpersonal-psychological theory of suicide (IPTS); these include burdensomeness, failed belonging, and acquired capability. METHODS: Qualitative semistructured interviews were conducted with 68 Soldiers at 3 months post-OEF/OIF deployment. Soldiers were asked about changes in their experiences of pain, burdensomeness, and lack of belonging. The methodology employed was descriptive phenomenological. RESULTS: Transcripts were reviewed and themes related to the IPTS constructs emerged. Soldiers' postdeployment transition experiences included higher pain tolerance, chronic pain, emotional reactivity, emotional numbing and distancing, changes in physical functioning, combat guilt, discomfort with care seeking, and difficulties reintegrating into family and society. CONCLUSIONS: Findings highlight the utility of the IPTS in understanding precursors to suicide associated with transition from deployment, as well as treatment strategies that may reduce risk in Soldiers during reintegration.

All-cause mortality among United States military personnel: Findings from the Millennium Cohort Study, 2001-2021.

PURPOSE: The goal of this study was to estimate all-cause mortality among Operations Enduring Freedom, Iraqi Freedom, and New Dawn era service members and veterans and to identify protective and risk factors for mortality. METHODS: Using 20 years of longitudinal data from the Millennium Cohort Study (2001-2021), sequential Cox proportional hazard models were conducted to examine demographic, military, and health-related characteristics associated with all-cause mortality among service members and veterans. RESULTS: Among 201,619 participants, 3806 (1.9 %) were deceased by the end of the observation period, with an age- and sex-adjusted incidence of 37.6 deaths per 100,000 person-years. Deployed service members had lower all-cause mortality risk than those who did not deploy. Personnel who experienced combat had higher mortality risk compared with those who did not in unadjusted models; this association was nonsignificant after accounting for health-related factors. Enlisted and Army personnel both had a higher mortality risk, while women and Hispanic individuals had a lower risk. Stressful life events, lower physical health related quality of life, problem drinking, and smoking were also associated with greater mortality risk. CONCLUSION: These profiles may be useful for developing preventive education and intervention efforts in military and veteran populations to reduce premature mortality.

Combat experiences, pre-deployment training, and outcome of exposure therapy for post-traumatic stress disorder in Operation Enduring Freedom/Operation Iraqi Freedom veterans.

The association between exposure to multiple potentially traumatic events (PTEs) and subsequent increased risk of post-traumatic stress disorder (PTSD) is well established. However, less is known about the relation between exposure to numerous PTEs, as is typical with military service, and treatment outcome. Furthermore, there has been little research examining military specific protective factors, such as pre-deployment preparedness, on PTSD treatment response. The current study investigated combat exposure and potential moderators of treatment outcome for exposure therapy in Operation Enduring Freedom/Operation Iraqi Freedom (OEF/OIF) veterans with PTSD. One hundred and eleven OEF/OIF veterans diagnosed with PTSD participated in 8 weeks of exposure therapy. Results indicated that increased combat exposure was associated with a reduced rate of change in PTSD symptoms but not depression symptoms. These findings were consistent across two measures of combat exposure. There was preliminary support for the moderating effect of pre-deployment preparedness on the association between combat exposure and treatment response. Together, these findings suggest that increased combat exposure is associated with poor treatment response in veterans with PTSD; however, this can be reduced by elevated pre-deployment preparedness.

Metabolic and quality of life effects of growth hormone replacement in patients with TBI and AGHD: A pilot study.

OBJECTIVE: Traumatic brain injury (TBI), a common cause of adult growth hormone deficiency (AGHD), affects 20% of Veterans returning from Iraq and Afghanistan (OEF/OIF/OND). Growth hormone replacement therapy (GHRT) improves quality of life (QoL) in AGHD but remains unexplored in this population. This pilot, observational study investigates the feasibility and efficacy of GHRT in AGHD following TBI. DESIGN: In this 6-month study of combat Veterans with AGHD and TBI starting GHRT (N = 7), feasibility (completion rate and rhGH adherence) and efficacy (improvements in self-reported QoL) of GHRT were measured (primary outcomes). Secondary outcomes included body composition, physical and cognitive function, psychological and somatic symptoms, physical activity, IGF-1 levels and safety parameters. It was hypothesized that participants would adhere to GHRT and that QoL would significantly improve after six months. RESULTS: Five subjects (71%) completed all study visits. All patients administered daily rhGH injections, 6 (86%) of whom consistently administered the clinically-prescribed dose. While QoL demonstrated numeric improvement, this change did not reach statistical significance (p = 0.17). Significant improvements were observed in total lean mass (p = 0.02), latissimus dorsi strength (p = 0.05), verbal learning (Trial 1, p = 0.02; Trial 5, p = 0.03), attention (p = 0.02), short-term memory (p = 0.04), and post-traumatic stress disorder (PTSD) symptoms (p = 0.03). Body weight (p = 0.02) and total fat mass (p = 0.03) increased significantly. CONCLUSION: GHRT is a feasible and well-tolerated intervention for U.S. Veterans with TBI-related AGHD. It improved key areas impacted by AGHD and symptoms of PTSD. Larger, placebo-controlled studies testing the efficacy and safety of this intervention in this population are warranted.

An interdisciplinary approach to the screening, diagnosis, and treatment of OEF/OIF Veterans with mild traumatic brain injury.

OBJECTIVE: To implement an Integrated TBI Screening Clinic (ITSC) during the mandatory TBI evaluation process at the Department of Veterans Affairs. Referral outcomes were examined regarding Veterans who were determined to need a full neuropsychological evaluation versus those for whom mental health treatment was clinically indicated. Correlations among cognitive measures, posttraumatic stress disorder (PTSD), anxiety, depression, and insomnia symptoms were also examined. METHOD: This study was a retrospective chart review study that included 138 Veterans seen between 2011 and 2014 in a post-deployment primary care clinic. Descriptive statistics and correlations were completed using the: screening Module of the Neuropsychological Assessment Battery (S-NAB), PTSD Checklist-Military version (PCL-M), Beck Depression Inventory-II (BDI-II), Beck Anxiety Inventory (BAI), and Insomnia Severity Index (ISI). RESULTS: 19.8% of Veterans required a referral for a full neuropsychological exam and 72.7% were referred for additional mental health services (with some Veterans being referred to both). Significant correlations were found among higher PTSD, depression, anxiety symptoms, with poorer attention and memory (all p < .05). Only PTSD was significantly correlated with poorer executive functioning (r = 0.19, p < .05). CONCLUSION: Integration of a multidisciplinary neuropsychological screening exam during a primary care visit with OEF/OIF Veterans may assist in better delineating symptoms.

Rationale and design of an efficacy study of Group Prolonged Exposure for PTSD.

INTRODUCTION: Among health problems in the Veteran population, the most common is posttraumatic stress disorder (PTSD) and its effect on the quality of life. Prolonged Exposure therapy, based on emotional processing theory, is a first-line treatment for reducing PTSD symptom severity when delivered in an individual format, and its efficacy is well established. The primary objective of this study is to establish the efficacy of prolonged exposure delivered in a small 3-person group modality. Quality of life should improve with decreases in PTSD symptoms such as sleep disturbance, irritability, and hypervigilance. Stigma is associated with hesitation in seeking treatment and treatment dropout. A secondary objective is to measure the effect of group treatment on reducing the stigma surrounding PTSD. METHODS/DESIGN: This study is a randomized controlled trial testing the efficacy of Group Prolonged Exposure (PE) for reducing PTSD symptom severity and improving quality of life in male Afghanistan and Iraq Veterans. All participants are randomly assigned to receive Group PE or Group Present-Centered Therapy (PCT) for 10-weekly, 90-min sessions. Group PE focuses on processing trauma memories, while the goal of Group PCT is improved psychosocial functioning through management of current stressors. The primary outcome is improvement in CAPS-5 PTSD symptom severity scores and quality of life measures (WHO-QOL and SF-36) from pre-treatment to post-treatment, 3-months post-treatment, and 6-months post-treatment. A secondary outcome is reductions in perceived self-stigma of mental illness based on the Stigma Scale at baseline and follow-up points. This study is designed to expand access to this first-line treatment for PTSD by delivering PE in a small group modality while conforming to the individual PE protocol, with group treatment reducing perceived stigma of mental illness.

OEF/OIF/OND Veterans Seeking PTSD Treatment: Perceptions of Partner Involvement in Trauma-Focused Treatment.

INTRODUCTION: Post-traumatic stress disorder (PTSD) has been linked to a variety of adverse mental and physical health outcomes including distressed relationships. Involving romantic partners in PTSD treatment appears to be a promising new avenue for PTSD treatment; however, additional research is necessary to clarify veteran preferences for inclusion of significant others in treatment and relationship characteristics that may influence such preferences. Accordingly, the present study was designed to evaluate Operation Enduring Freedom/Operation Iraqi Freedom/Operation New Dawn (OEF/OIF/OND) veterans' desire to include romantic partners in trauma-focused care (n = 74) and to explore psychological and relationship variables associated with preference for partner inclusion in PTSD treatment. MATERIALS AND METHODS: This study surveyed male (N = 74) OEF/OIF/OND combat veterans seeking mental health services at a Veterans Health Administration PTSD treatment program. Relationships between PTSD symptoms, romantic relationship functioning, and interest in including their romantic partner in PTSD treatment were examined. RESULTS: Consistent with previous research, OEF/OIF/OND veterans seeking treatment at a specialty PTSD program report low relationship satisfaction. The majority of participants reported that PTSD symptoms interfere with relationship functioning; specifically, numbing symptoms were a significant predictor of PTSD-related relationship impairment. A minority (26%) of participants reported a desire to include their romantic partner in PTSD treatment. Greater behavioral avoidance and communication difficulties were associated with increased interest in including a romantic partner in PTSD treatment. CONCLUSION: We confirmed that OEF/OIF/OND veterans seeking PTSD treatment experience PTSD-related problems in romantic relationships, low-relationship satisfaction, and relationship satisfaction was positively associated with perceived communication and problem-solving skills. A minority of veterans were interested in involving significant others in their PTSD treatment; however, in the present study, veterans were not given information about the various ways that a romantic partner might be involved in treatment, and they were not presented with specific conjoint therapies (e.g., Cognitive-Behavioral Conjoint Therapy for PTSD, Strategic Approach Therapy). For veterans with PTSD, relationship distress, and communication difficulties, conjoint psychotherapies may offer a way of increasing engagement in PTSD treatment by parsimoniously addressing multiple treatment targets at once (PTSD symptoms, relationship distress, communication problems) and providing veteran-centered care.

Knowledge Gaps around Smoking and Nicotine among U.S. Military Veterans Who Smoke and Implications for Practice.

The present study describes the knowledge about smoking and nicotine among a sample of current Iraq-/Afghanistan-era veterans who smoke (N = 117). A majority of participants had knowledge regarding general risks of smoking and benefits of nicotine replacement therapy. However, many participants underestimated their personal cardiovascular and cancer risk as a smoker. Many participants also inaccurately believed that nicotine causes cancer and that nicotine medications work by making one physically sick if used while smoking. These beliefs could lead to reluctance to use nicotine replacement therapy. Discussion of findings offers potential solutions in the form of patient education as well as emphasis on training healthcare providers training on best practices for patient education (beyond simple advice to quit). More nuance and detail in patient education may facilitate increased knowledge about smoking and nicotine among U.S. military veterans with the ultimate goal of increasing cessation rates.

Traumatic Brain Injury and Posttraumatic Stress Disorder: Comorbid Consequences of War.

Scientific literature is reviewed supporting a "consequence of war syndrome (CWS)" in Operation Enduring Freedom/Operation Iraqi Freedom/Operation New Dawn soldiers. CWS constituents include chronic pain and insomnia, other physical complaints, posttraumatic stress disorder (PTSD), anxiety, depression, and neuropsychological deficits. The foundation of CWS lies with the chronic stressors inherent to deployment and the cascade of biological events mediated and maintained by hypothalamic-pituitary-adrenal (HPA) axis dysregulation. Such dysregulation is modified by the individual's specific experiences at war, difficulty reintegrating to post-deployment life, and the onset or exacerbation of the chronic and comorbid physical, emotional, and cognitive disorders. The circuit network between the prefrontal cortex (PFC), amygdala, and hippocampus is particularly sensitive to the consequences of war. The review's specific conclusions are as follows: HPA axis dysregulation contributes to the chronic insomnia and hyperarousal seen in soldiers. There is considerable symptom overlap between PTSD and blast-related head injury, and it is difficult to determine the relative contributions of the two disorders to abnormal imaging studies. In some cases, traumatic brain injury (TBI) may directly precipitate PTSD symptoms. While not intuitive, the relationship between TBI and postconcussion syndrome appears indirect and mediated through PTSD. Blast-related or conventional head injury may have little long-term impact on neuropsychological functioning; contrarily, PTSD particularly accounts for current cognitive deficits. The psychological experience of CWS includes a "war-within" where soldiers continue to battle an internalized enemy. Successful treatment of CWS entails transdisciplinary care that addresses each of the constituent disorders.

Accelerated Changes in Cortical Thickness Measurements with Age in Military Service Members with Traumatic Brain Injury.

Finding objective and quantifiable imaging markers of mild traumatic brain injury (TBI) has proven challenging, especially in the military population. Changes in cortical thickness after injury have been reported in animals and in humans, but it is unclear how these alterations manifest in the chronic phase, and it is difficult to characterize accurately with imaging. We used cortical thickness measures derived from Advanced Normalization Tools (ANTs) to predict a continuous demographic variable: age. We trained four different regression models (linear regression, support vector regression, Gaussian process regression, and random forests) to predict age from healthy control brains from publicly available datasets (n = 762). We then used these models to predict brain age in military Service Members with TBI (n = 92) and military Service Members without TBI (n = 34). Our results show that all four models overpredicted age in Service Members with TBI, and the predicted age difference was significantly greater compared with military controls. These data extend previous civilian findings and show that cortical thickness measures may reveal an association of accelerated changes over time with military TBI.

Demographic, Military, and Health Characteristics of VA Health Care Users and Nonusers Who Served in or During Operation Enduring Freedom or Operation Iraqi Freedom, 2009-2011.

An estimated 60% of all Operation Enduring Freedom / Operation Iraqi Freedom (OEF/OIF) veterans who have left the military had used the US Department of Veterans Affairs (VA) for health care services as of March 31, 2015. What is not known, however, are the differences in demographic, military, and health characteristics between OEF/OIF veterans who use the VA for health care and OEF/OIF veterans who do not. We used data from the 2009-2011 National Health Study for a New Generation of US Veterans to explore these differences. We found that VA health care users were more likely than non-VA health care users to be non-Hispanic black, to be unmarried, to have served on active duty and in the army, to have been deployed to OEF/OIF, and to have an annual income less than $35 000. The prevalence of 21 chronic medical conditions was higher among VA health care users than among non-VA health care users. OEF/OIF veterans using the VA for health care differ from nonusers with respect to demographic, military, and health characteristics. These data may be useful for developing programs and policies to address observed health disparities and achieve maximum benefit for the VA beneficiary population.

Intervention Efficacy in Engaging Black and White Veterans with Post-traumatic Stress Disorder into Treatment.

This study examined racial differences among Black and White Veterans who screened positive for post-traumatic stress disorder (PTSD) but were not in PTSD treatment and were participating in an intervention trial. Operation Enduring Freedom (OEF) and Operation Iraqi Freedom (OIF) Veterans with PTSD but not yet engaged in treatment were recruited and randomly assigned to control or intervention conditions. Intervention participants received a cognitive-behavioral engagement intervention by phone. All participants received follow-up calls to assess symptoms and utilization of treatment. Black and White participants were compared to assess differences in treatment utilization. Intervention session notes were analyzed qualitatively for explanatory themes. Participants of both races who received the intervention had higher PTSD treatment initiation than their respective control groups (Blacks: 85% vs. 58% and Whites: 53% vs. 45%, respectively). However, Blacks completed fewer PTSD treatment sessions compared to Whites overall (M = 2.06 [SD = 2.3] vs. M = 3.77 [SD = 9.9]; p < .05). Within the intervention condition, Blacks were significantly more likely to initiate treatment (odds ratio = 2.3, p < .04), and had a greater reduction in PTSD symptom compared to Whites (PTSD Checklist - Military Version [PCL] scores: 12.75 vs. 9.68). Based on qualitative analysis of intervention session notes, themes emerged that may suggest cultural differences involving social connection, attitudes towards treatment, and the desire to appear "okay." Blacks had a higher initiation rate and greater reduction in PTSD severity but completed fewer treatment sessions than Whites. These are promising results with respect to other studies which demonstrate that Black Veterans are less likely to seek treatment for PTSD.

Sexual revictimization among Iraq and Afghanistan war era veterans.

Research in both civilian and military populations has demonstrated that females who experience childhood sexual abuse (CSA) are more likely to experience sexual assault in adulthood than females who did not experience CSA. Among veteran samples, however, little research has examined previous sexual assault as a risk factor of military sexual assault and post-military sexual assault, and very little research has examined revictimization in male veterans. The purpose of this study was to examine risk of sexual revictimization in a sample of veterans who served during the wars in Iraq and Afghanistan. A sample of 3106 veterans (80.4% male) completed a measure of lifetime exposure to traumatic events, including sexual abuse and sexual assault. Logistic regression analyses were used to examine previous sexual abuse/assault as predictors of later sexual assault; analyses were conducted separately for males and females. In general, previous sexual abuse/assault was associated with later sexual assault in both male and female veterans. These findings have important assessment and treatment implications for clinicians working with veterans.
