Identifying candidate mechanisms of comorbidity in disordered eating and posttraumatic stress disorder symptoms among U.S. veterans: A network analytic approach.

OBJECTIVE: Comorbidity between posttraumatic stress disorder (PTSD) and disordered eating (DE) symptoms is common, reflecting a possible reciprocal relationship between these disorders. Network analysis may reveal candidate mechanisms underlying their comorbidity and highlight important treatment targets. METHOD: Two national samples of U.S. veterans endorsing trauma exposure self-reported PTSD and DE symptoms. The discovery sample included veterans from all service eras (n = 434). The validation sample included recently separated post-9/11 veterans (n = 507). We fit graphical lasso models to evaluate the network structure of PTSD factors based on the seven-factor "hybrid" model and DE symptoms within each sample. We used strength scores to identify the most central symptoms within the networks and identified bridge symptoms connecting PTSD and DE features. We tested for network invariance between self-identified men and women within each sample and across the studies. RESULTS: PTSD and DE symptoms clustered as expected within networks for each sample. The strongest nodes in the networks included both PTSD and DE features. The strongest bridge symptoms in both studies included overevaluation of shape and weight, negative affect, and avoidance. Networks were invariant across men and women in each sample and largely invariant across samples. CONCLUSIONS: Cross-sectional network models of PTSD and DE symptoms largely replicated across national samples of U.S. veterans and between men and women within samples. Cognitive features of both disorders, along with avoidance, may partially underlie comorbidity and represent potential treatment targets.

Associations between DSM-5 posttraumatic stress disorder Criterion E2 endorsement and selected self-destructive behaviors in recent-era veterans: A focus on disordered eating.

Revisions to the posttraumatic stress disorder (PTSD) criteria in the DSM-5 included a new criterion in the alterations in arousal and reactivity cluster (i.e., engagement in reckless and self-destructive behaviors; Criterion E2). Despite its clinical significance, little is known about how this symptom corresponds to engagement in specific direct and indirect self-harm behaviors. We examined associations between E2 and self-reported recent engagement in direct and indirect self-harm behaviors, including disordered eating, which is not included in the prototypical E2 symptom scope, in a trauma-exposed sample of 1,010 recent-era veterans (61.5% self-identified women, 38.5% self-identified men). We also tested whether gender moderated these associations. We repeated analyses in a subsample of participants with clinically elevated PTSD symptoms. Participants self-reported past-month PTSD symptoms (PCL-5) as well as past-month nonsuicidal self-injury, suicidal ideation, suicide planning, fasting, purging, binge eating, compulsive exercise, and problematic alcohol and drug use. We found no evidence for moderation by gender for any of the behaviors examined in the main sample. However, after controlling for gender and demographic covariates, weighted logistic regressions showed small, significant associations between E2 score and direct self-harm behaviors, substance use, purging, and binge eating, aORs = 1.30-1.91. Criterion E2 was linked to behaviors included in the typical symptom scope (self-directed violence, substance use) and those that are not (disordered eating behaviors). Comprehensive screening for self-destructive behaviors, including disordered eating, among veteran men and women who endorse Criterion E2 is indicated.

Emergence of probable PTSD among U.S. veterans over the military-to-civilian transition.

OBJECTIVE: Despite theorizing that posttraumatic stress disorder (PTSD) symptomatology may be exacerbated during the military-to-civilian transition, little research has delved into the trajectory of trauma-related symptomatology or the impact of diverse factors on timing of PTSD onset. To understand risk and protective factors for PTSD during the transition into civilian life, this study examined demographic, experiential, and psychosocial characteristics that may explain variation in PTSD symptoms and timing of onset. METHOD: A nationwide sample representing 48,965 U.S. veterans separating from military service in fall 2016 responded to six Web-based surveys over 3 years. Assessments included PTSD symptoms, stress, warfare exposures, military sexual trauma, moral injury events, resilience, and social support. Multivariable models estimated covariates of positive PTSD screen or symptoms. RESULTS: Trauma exposure during military service was high at 59%. Probable PTSD was detected in 26% of the sample at baseline, with additional cases in each survey wave for an overall rate of 30%. Meeting criteria for probable PTSD covaried with current stress, female gender, and minority race/ethnicity; baseline psychological resilience and concurrent social support mitigated the risk. PTSD symptoms correlated positively with stress levels at current and previous time points. Social support was protective but only when contemporaneous with the PTSD symptoms. CONCLUSIONS: This study illustrates the need for ongoing social support for veterans coping with symptoms of PTSD, life stressors, and postmilitary trauma, suggesting a countervailing influence of psychological resilience and contemporaneous (but not historical) social support on symptom exacerbation.

Gender differences in direct and indirect associations of trauma types with disordered eating in a national U.S. veteran sample.

OBJECTIVE: Disordered eating (DE) in military veterans has been linked to trauma exposure, but the mechanisms underlying this association remain unclear. The current study documented the direct associations of DE with multiple trauma types in a gender-balanced sample of veterans and examined indirect associations of trauma and DE via self-reported PTSD symptoms and concerns about shape and weight. METHOD: Participants included 1,187 veterans (50% women, 46% men, 4% another) from multiple service eras. Sampling weights were applied to enhance representativeness to the national veteran population. RESULTS: Gender-stratified, weighted models revealed associations of premilitary, warfare, and postseparation trauma with DE in men and associations of premilitary, military sexual (MST), and postseparation trauma with DE in women. Monte Carlo estimation of indirect effects showed support for indirect associations of premilitary, warfare, and postseparation-related trauma/stressor exposure with DE via PTSD symptoms among men; postseparation stressors were also indirectly associated with DE via shape and weight concerns. Among women, each trauma type was indirectly associated with DE via shape and weight concerns but not PTSD symptoms. When trauma exposures were examined concurrently, MST and postseparation trauma exposure were uniquely associated with DE via shape and weight concerns among women. Only the indirect association of postseparation trauma/stressor exposure with DE via shape and weight concerns was significant among men. CONCLUSIONS: Findings support the need for gender-specific interventions that target different mechanisms contributing to DE symptoms among veterans.

Mental health literacy in veterans: What do U.S. military veterans know about PTSD and its treatment?

Given military veterans' underutilization of posttraumatic stress disorder (PTSD) treatment, it is important to explore factors that may facilitate or stand in the way of treatment seeking for this population. The purpose of this study was to provide an initial examination of military veterans' mental health literacy as it relates to PTSD and its treatment. One-hundred and 32 post-9/11 veterans were recruited for this web-based study. A vignette-based approach was employed to examine veterans' mental health literacy and relationships between mental health literacy and dimensions of stigma. Consistent with hypotheses, results revealed relatively higher levels of PTSD problem recognition, and lower levels of knowledge about evidence-based treatments and self-help strategies within this veteran sample. Correlational results provided partial support for our hypotheses: Mental health literacy was inversely associated with negative beliefs about mental health problems and treatments, but not significantly related to other dimensions of stigma. This study highlights potential targets for mental health literacy interventions and points to the value of additional research on the role of mental health literacy in veterans' treatment seeking.

The Impact of Posttraumatic Stress Disorder and Moral Injury on Women Veterans' Perinatal Outcomes Following Separation From Military Service.

Posttraumatic stress disorder (PTSD) has been found to lead to several adverse perinatal outcomes in the general population. Preliminary research has found that women veterans with PTSD have an increased prevalence of preterm birth, gestational diabetes, and preeclampsia. Less research has examined the role of moral injury (MI) in perinatal outcomes. This longitudinal survey study examined the impact of PTSD symptoms and MI on prospectively assessed adverse perinatal outcomes among women who became pregnant in the first 3 years after separating from U.S. military service (N = 318). The Moral Injury Events Scale was used to assess the degree to which individuals experienced distress related to transgressions of deeply held moral beliefs, and the Primary Care PTSD Screen for DSM-5 (PC-PTSD) was used to assess PTSD symptoms. Perinatal outcomes included experiencing an adverse pregnancy outcome (e.g., preterm birth, gestational diabetes), postpartum depression and/or anxiety, and perceived difficult pregnancy. Although both PTSD symptoms, adjusted odds ratio (aOR) = 1.16, 95% CI [1.00, 1.35]; and MI, aOR = 1.27, 95% CI [1.06, 1.41], emerged as significant predictors of adverse pregnancy outcomes, only PTSD symptoms were a significant predictor of postpartum depression and/or anxiety, aOR = 1.43, 95% CI [1.22, 1.68], and perception of a difficult pregnancy, ß = .31, when controlling for lifetime trauma exposure, age, socioeconomic status, and ethnic/racial minority status. The results indicate that both PTSD symptoms and MI are associated with adverse perinatal outcomes, supporting the potential need to screen for both PTSD and MI during the perinatal period.

U.S. Military Veterans' Health and Well-Being in the First Year After Service.

INTRODUCTION: This study examined the health and well-being of U.S. veterans during the first year after military service and tested several hypotheses regarding differences in veterans' well-being over time, across life domains, and based on sex, military rank, and deployment history. METHODS: A national sample of 9,566 veterans was recruited from a roster of all separating U.S. service members in the fall of 2016. Veterans' status, functioning, and satisfaction with regard to their health, work, and social relationships were assessed within 3 months of separation and then 6 months later. Analyses were completed in 2019. RESULTS: Health concerns were most salient for newly separated veterans, with many veterans reporting that they had chronic physical (53%) or mental (33%) health conditions and were less satisfied with their health than either their work or social relationships. By contrast, most veterans reported relatively high vocational and social well-being and only work functioning demonstrated a notable decline in the first year following separation. Enlisted personnel reported consistently poorer health, vocational, and social outcomes compared with their officer counterparts, whereas war zone-deployed veterans reported more health concerns and women endorsed more mental health concerns compared with their nondeployed and male peers. CONCLUSIONS: Although most newly separated veterans experience high vocational and social well-being as they reintegrate into civilian life, findings point to the need for additional attention to the health of separating service members and bolstered support for enlisted personnel to prevent the development of chronic readjustment challenges within this population.

An Examination of the Roles of Mental Health Literacy, Treatment-Seeking Stigma, and Perceived Need for Care in Female Veterans' Service Use.

OBJECTIVE: Little is known about the role of mental health literacy in military veterans' treatment-seeking stigma and service use, or the impact of these factors on perceived need for mental health care. In addition, most research has focused on mixed-gender samples. This study examined the relationships among mental health literacy, treatment seeking stigma, perceived need for mental health care, and service use in a national, longitudinal study of female veterans. METHODS: A sample of 171 female veterans were drawn from a larger three-wave prospective national survey conducted between 2014 and 2017. RESULTS: Path analyses revealed that treatment seeking stigma had a direct negative effect on service use and an indirect effect that was mediated by perceived need for care, such that higher treatment seeking stigma was associated with lower perceived need for mental health care. Mental health literacy had an indirect effect on service use via its inverse association with treatment-seeking stigma. In contrast, mental health literacy was not associated with perceived need. CONCLUSIONS: Mental health literacy, treatment-seeking stigma, and perceived need for care affect female veterans' service use in unique ways. Further longitudinal research is needed to better understand these pathways in diverse samples.

Cultural and service factors related to mental health beliefs among post-9/11 veterans.

BACKGROUND AND AIMS: The primary purpose of this study was to examine cultural and demographic predictors of dimensions of anticipated stigma and negative mental health beliefs, known barriers to mental health care utilization, among post-9/11 veterans. METHODS: A cross-sectional survey methodology was used to assess 132 post-9/11 veterans. Bivariate correlations were used to examine associations between military cultural values (self-reliance and emotional control), demographic variables (gender and service characteristics) and dimensions of anticipated stigma and negative beliefs about mental health. Descriptive statistics were used to examine item-level agreement on scales of stigma, mental health beliefs and cultural values to more fully describe these beliefs in this population. RESULTS: Descriptive findings revealed that the most highly endorsed dimension of stigma was anticipated stigma from coworkers. Correlational findings indicated that only exaggerated self-reliance, not emotional control, was positively associated with higher negative beliefs about treatment and treatment-seeking, and not other dimensions of negative beliefs about mental health. Active duty service members and those who deployed reported higher negative beliefs about treatment-seeking, emotional control and self-reliance. In addition, men reported higher negative beliefs about treatments, treatment-seeking and self-reliance than women. CONCLUSION: These results highlight the importance of addressing concerns about self-reliance and mental health treatment in stigma-reduction interventions especially among male, deployed, and active duty service members to reduce stigma and stigma-related barriers to care.

Gender differences in posttraumatic stress symptoms among OEF/OIF veterans: an item response theory analysis.

Establishing whether men and women tend to express different symptoms of posttraumatic stress in reaction to trauma is important for both etiological research and the design of assessment instruments. Use of item response theory (IRT) can reveal how symptom reporting varies by gender and help determine if estimates of symptom severity for men and women are equally reliable. We analyzed responses to the PTSD Checklist (PCL) from 2,341 U.S. military veterans (51% female) who completed deployments in support of operations in Afghanistan and Iraq (Operation Enduring Freedom/Operation Iraqi Freedom [OEF/OIF]), and tested for differential item functioning by gender with an IRT-based approach. Among men and women with the same overall posttraumatic stress severity, women tended to report more frequent concentration difficulties and distress from reminders whereas men tended to report more frequent nightmares, emotional numbing, and hypervigilance. These item-level gender differences were small (on average d = 0.05), however, and had little impact on PCL measurement precision or expected total scores. For practical purposes, men's and women's severity estimates had similar reliability. This provides evidence that men and women veterans demonstrate largely similar profiles of posttraumatic stress symptoms following exposure to military-related stressors, and some theoretical perspectives suggest this may hold in other traumatized populations.

Posttraumatic maladaptive beliefs scale: evolution of the personal beliefs and reactions scale.

The posttraumatic maladaptive beliefs scale (PMBS) was developed to measure maladaptive beliefs about current life circumstances that may occur following trauma exposure. This scale assesses maladaptive beliefs within three domains: (a) threat of harm, (b) self-worth and judgment, and (c) reliability and trustworthiness of others. Items for the PMBS were drawn from a larger preexisting measure that assesses a wide range of personal beliefs and reactions associated with trauma exposure. The construct validity of the PMBS was assessed in two independent samples of interpersonal trauma survivors. This article provides data to support the reliability and validity of the PMBS as an instrument to assess general, rather than trauma-specific, maladaptive beliefs that have relevance for functioning in the aftermath of a traumatic event. Moreover, the measure is sensitive to changes that occur in treatment, and the length of the measure (15 items) is practical for use in clinical settings.

Posttraumatic stress symptomatology as a mediator of the association between military sexual trauma and post-deployment physical health in women.

This study examined posttraumatic stress symptomatology (PSS) as a mediator of the association between military sexual trauma and post-deployment physical health. Relationships were examined in a sample of 83 female veterans of the first Gulf War (1990-1991) approximately 10 years post-deployment. Participants reported on the frequency of sexual harassment and sexual assault experienced during deployment. Physical health was measured using participants' self-reports of pre-deployment and post-deployment symptoms within 7 body systems. Sexual harassment exposure was not found to be associated with PSS-mediated associations with physical health symptoms. However, sexual assault during deployment was found to be associated with PSS and 4 of the 7 health symptom clusters assessed: gastrointestinal, genitourinary, musculoskeletal, and neurological symptoms. Furthermore, PSS was found to be a significant mediator of the sexual assault-physical health relationship in each of these domains, with the indirect path accounting for 74% to 100% of the relationship. The findings from the current study indicate that sexual assault has detrimental associations with physical health and that PSS plays a primary role in that relationship.

Pretrauma problems, prior stressor exposure, and gender as predictors of change in posttraumatic stress symptoms among physically injured children and adolescents.

OBJECTIVE: This study addressed predictors of change in posttraumatic stress symptoms (PTSS) among youths who had experienced physical injuries. The influences of pretrauma internalizing and externalizing problems, prior stressor exposure, and gender were investigated. Additionally, gender was examined as a moderator of the associations between internalizing problems and PTSS, externalizing problems and PTSS, and prior stressor exposure and PTSS. METHOD: Participants were 157 children and adolescents (75% male; age M = 13.30 years, SD = 3.60; 44% Caucasian, 39% African American, 13% Hispanic, and 4% other) admitted to 2 hospitals for physical injuries. Youths and their parents completed measures of PTSS (Child Posttraumatic Stress Reaction Index), internalizing and externalizing problems (Child Behavior Checklist), and prior stressor exposure (Coddington Life Events Scale, Child) during the hospital stay; youths completed up to 3 additional PTSS assessments targeted at 3, 6, and 12 months postinjury. RESULTS: Multilevel regression analyses revealed a significant average decline in PTSS over time (p < .05) that followed a curvilinear trajectory. Externalizing problems, prior stressor exposure, and female gender predicted higher initial PTSS levels (p < .05). Gender moderated the influence of internalizing problems, externalizing problems, and prior stressor exposure on decline in PTSS over time (p < .05). Patterns of recovery for those with high and low levels of each characteristic differed for girls and boys. CONCLUSIONS: Findings suggest targets for clinical consideration, both with respect to identifying subgroups of children and adolescents that may warrant early assessment and monitoring and timing of more directed PTSS treatment intervention.

Cognitive and affective predictors of treatment outcome in Cognitive Processing Therapy and Prolonged Exposure for posttraumatic stress disorder.

This study examined cognitive and affective predictors of treatment dropout and treatment efficacy in Cognitive Processing Therapy (CPT) and Prolonged Exposure (PE) for PTSD. Study participants were women with PTSD from a sexual assault who received at least one session of either treatment (n = 145) as part of a randomized clinical trial. Results revealed that younger age, lower intelligence, and less education were associated with higher treatment dropout, whereas higher depression and guilt at pretreatment were associated with greater improvement in PTSD symptomatology. Results by treatment condition indicated that women with higher anger at pretreatment were more likely to dropout of PE and that older women in PE and younger women in CPT had the best overall outcomes. These findings have implications for efforts to enhance treatment efficacy and retention in CBT treatment protocols.

Personality and fear responses during conditioning: Beyond extraversion.

The personality domain of introversion-extraversion has been theorized to be associated with the strength of fear conditioning, but the literature on this topic has been equivocal. Furthermore, except for extraversion and neuroticism, relationships of the other Big Five personality domains with fear response acquisition have not been explored. In the current study, multi-level modeling was used to examine the relationships of facets of the Big 5 domains to fear response acquisition. Participants were 217 police and firefighter trainees who completed the Revised NEO Personality Inventory (NEO-PI-R; Costa & McCrae, 1992) and a fear conditioning task as part of a larger study. Results indicated that several facets of extraversion have opposing associations with fear response acquisition of an electrodermal response- possibly contributing to the mixed results in the literature. Additionally, facets of other Big Five domains were found to be associated with fear response acquisition.

Deployment stressors of the Iraq War: insights from the mainstream media.

A comprehensive understanding of the stressors of the Iraq War is needed to ensure appropriate postdeployment assessments and to inform empirical inquiries. Yet we are unaware of any published studies that address the range of stressors experienced by this cohort. Thus, in the present study, we report the results of an interpretive literature review of mainstream media reports published from the beginning of the Iraq War in March 2003 to March 2005. This literature revealed a combination of stressors associated with traditional combat, insurgency warfare, and peacekeeping operations. The increasing deployment of National Guard/Reservist personnel, older soldiers, and women highlights additional stressors associated with sexual harassment and assault, preparedness and training, and life and family disruptions. This is a cause for concern as war-zone stressors have been implicated in postdeployment health outcomes, including intimate partner violence and child maltreatment, immediate physical and mental health, and long-term adjustment.

Risk factors for mental, physical, and functional health in Gulf War veterans.

Risk factors associated with war-zone events and circumstances are implicated in the health and adjustment of military veterans. We assessed a national stratified sample of community-residing veterans of the Gulf War (N = 357) using scales from the Deployment Risk and Resilience Inventory, along with an array of mental (posttraumatic stress disorder, depression, and anxiety), physical (symptom and condition indicators especially pertinent to Gulf War illnesses), and functional (both mental and physical dimensions) health outcomes. We found that perceived threat or fear of bodily harm in the war zone and self-reported or perceived exposures to environmental hazards may play a critical role in all measured aspects of health. Moreover, a synergistic effect of these two risk factors was observed in the prediction of mental health and mental health functional status.

Toward gender-aware health care: evaluation of an intervention to enhance care for female patients in the VA setting.

In response to identified deficits in the provision of health care to female patients, we sought to improve healthcare workers' gender awareness- conceptualized as gender-role ideology, sensitivity, and knowledge related to female patients-through the application of a brief computerized educational intervention. This study, conducted in the Veterans Affairs (VA) health-care setting, involved a pretest-posttest equivalent control group design. We evaluated hypotheses using random coefficients regression, a technique that offers a number of advantages relative to repeated-measures ANOVA. Findings revealed significant improvements in sensitivity and knowledge for participants in the treatment condition compared to the control condition. With several exceptions, the intervention was similarly effective across employee groups.

Validation of scales from the Deployment Risk and Resilience Inventory in a sample of Operation Iraqi Freedom veterans.

The Deployment Risk and Resilience Inventory (DRRI) is a suite of scales that can be used to assess deployment-related factors implicated in the health and well-being of military veterans. Although initial evidence for the reliability and validity of DRRI scales based on Gulf War veteran samples is encouraging, evidence with respect to a more contemporary cohort of Operation Iraqi Freedom (OIF) veterans is not available. Therefore, the primary goal of the present study was to validate scales from the DRRI in a large sample of OIF army personnel diversified in occupational and demographic characteristics. In general, results supported the use of these DRRI scales in this population. Internal consistency reliability estimates were quite strong. Additionally, support was obtained for criterion-related validity, as demonstrated by associations with mental and physical health measures, and discriminative validity, as demonstrated by differences between key military subgroups.

Effects of military trauma exposure on women veterans' use and perceptions of Veterans Health Administration care.

BACKGROUND: Few studies have addressed how military trauma exposure, particularly sexual assault and combat exposure, affects women veterans' use and perceptions of Veterans Health Administration (VHA) care. OBJECTIVE: The aim of the present study was to evaluate the effects of military sexual assault and combat exposure on women veterans' use and perceptions of different aspects of VHA care. DESIGN: Cross-sectional telephone survey of a national sample of women veterans. PARTICIPANTS: Women from the VA's National Registry of Women Veterans. MEASUREMENTS: Sociodemographic characteristics, VHA care utilization, perceptions of care. RESULTS: Women veterans with histories of military sexual assault reported more use of VHA services, but less satisfaction, poorer perceptions of VHA facilities and staff, and more problems with VHA services compared to women veterans without histories of sexual assault. Combat exposure was related to more problems with VHA staff, although few other differences were observed for women with and without histories of combat exposure. CONCLUSIONS: Findings provide information on areas that can be targeted with respect to caring for women veterans exposed to military sexual trauma and combat exposure, including improving interactions with VHA staff and the ease of using VHA services.
