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.

Prevalence of Sexual Violence and Intimate Partner Violence Among US Military Veterans: Findings from Surveys with Two National Samples.

BACKGROUND: Sexual violence (SV) and intimate partner violence (IPV) experiences are major social determinants of adverse health. There is limited prevalence data on these experiences for veterans, particularly across sociodemographic groups. OBJECTIVE: To estimate the prevalence of SV before, during, and after military service and lifetime and past-year IPV for women and men, and explore differences across sociodemographic groups. DESIGN: Data are from two national cross-sectional surveys conducted in 2020. Weighted prevalence estimates of SV and IPV experiences were computed, and weighted logistic regression models were used for comparisons across gender, race, ethnicity, sexual orientation, and age. PARTICIPANTS: Study 1 included veterans of all service eras (N = 1187; 50.0% women; 29% response rate). Study 2 included recently separated post-9/11 veterans (N = 1494; 55.2% women; 19.4% response rate). MAIN MEASURES: SV was assessed with the Deployment Risk and Resilience Inventory-2 (DRRI-2). IPV was assessed with the extended Hurt-Insult-Threaten-Scream Tool. KEY RESULTS: Women were more likely than men to experience pre-military SV (study 1: 39.9% vs. 8.7%, OR = 6.96, CIs: 4.71-10.28; study 2: 36.2% vs. 8.6%, OR = 6.04, CIs: 4.18-8.71), sexual harassment and/or assault during military service (study 1: 55.0% vs. 16.8%, OR = 6.30, CIs: 4.57-8.58; study 2: 52.9% vs. 26.9%, OR = 3.08, CIs: 2.38-3.98), and post-military SV (study 1: 12.4% vs. 0.9%, OR = 15.49, CIs: 6.42-36.97; study 2: 7.5% vs. 1.5%, OR = 5.20, CIs: 2.26-11.99). Women were more likely than men to experience lifetime IPV (study 1: 45.7% vs. 37.1%, OR = 1.38, CIs: 1.04-1.82; study 2: 45.4% and 34.8%, OR = 1.60, CIs: 1.25-2.04) but not past-year IPV (study 1: 27.9% vs. 28.3%, OR = 0.95, CIs: 0.70-1.28; study 2: 33.1% vs. 28.5%, OR = 1.24, CIs: 0.95-1.61). When controlling for gender, there were few differences across other sociodemographic groups, with the exception of sexual orientation. CONCLUSIONS: Understanding veterans' experiences of SV and IPV can inform identification and intervention efforts, especially for women and sexual minorities.

The impact of stress and well-being during the COVID-19 pandemic on mental health in U.S. veterans.

The COVID-19 pandemic disrupted life around the globe and negatively impacted mental health (MH), including among military veterans. Building on previous research with U.S. veterans, the present study examined the association between a broad array of pandemic stressors and well-being on MH outcomes. A total of 372 veterans (51.3% women) from all service eras completed measures of posttraumatic stress disorder and depression during early (timepoint 1 [T1]) and peri-pandemic (timepoint 2 [T2]) periods. Pandemic-related stressors and well-being (satisfaction in life domains) were assessed at the peri-pandemic timepoint (T2). Logistic regression analyses were used to investigate associations between stressors and well-being with the likelihood of a probable MH diagnosis at T2 controlling for T1 MH status. More negative physical and MH impacts of the pandemic in addition to fewer positive consequences and lower satisfaction with paid work, finances, health, romantic relationships, and social life were associated with a higher likelihood of a probable T2 MH diagnosis. COVID infection was associated with lower odds of a probable T2 MH diagnosis. There were significant indirect effects, such that physical and MH impacts of the pandemic were associated with T2 MH via well-being. Overall, these findings highlight the role of stress and well-being on MH during a global pandemic. Interventions to address well-being may be important to address veteran MH during other periods of stress. Future research should examine the generalizability of study findings and further investigate factors that contribute to veterans' MH resilience during stressful life experiences.

Gender similarities and differences in associations between weight discrimination, shape/weight concerns, and eating disorder symptoms among post-9/11 veterans.

OBJECTIVE: Weight discrimination, defined as mistreatment of people based on body weight, is associated with body image concerns and eating disorder (ED) symptoms. Military veterans are particularly vulnerable to developing ED symptoms, which may be due to experiences of weight discrimination resulting from the military's strict weight and fitness requirements. However, no previous study has examined these associations among veterans. We investigated relationships between weight discrimination during and after military service and shape/weight concerns and ED symptoms in post-9/11 veterans. Based on evidence for gender differences in weight discrimination, body image, and ED symptoms, we also examined whether gender moderated these associations. METHOD: Participants were randomly selected from the population of post-9/11 U.S. veterans who had been discharged from the military within the previous 18 months. A total of 1494 veterans completed the Everyday Discrimination Scale, Eating Disorders Examination-Questionnaire, and the Eating Disorder Diagnostic Scale-5. RESULT: Women were more likely to report weight discrimination and had higher levels of ED symptoms and shape/weight concerns than men. Weight discrimination in and after leaving the military were positively associated with shape/weight concerns and ED symptoms in the full sample and among men and women. Gender moderated the association between weight discrimination after leaving the military and shape/weight concerns such that the association was stronger among men. DISCUSSION: Both male and female veterans may be vulnerable to developing ED symptoms, in part due to weight discrimination experienced during and after military service. Our findings emphasize the need to address weight discrimination and its consequences in veterans.

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.

The impact of the COVID-19 pandemic on eating disorders in U.S. military veterans.

PURPOSE: The COVID-19 pandemic has had a profound impact on mental health around the world. Although there have been reports that the incidence of eating disorders (EDs) has increased during the pandemic, few longitudinal studies have examined recent changes in EDs. Men and women with military histories may be particularly vulnerable to EDs, underscoring the importance of investigating the impact of the COVID-19 pandemic on EDs in this population. METHOD: We examined whether early-pandemic (Time 1; T1) posttraumatic stress disorder, depression, anxiety, and stress symptoms were associated with change in probable ED diagnostic status 1 year later (T2). We also investigated relationships from early pandemic mental health symptoms to change in ED diagnostic status from T1 to T2 via pandemic-related life circumstance pathways (health, financial, social, etc.). Participants included a population-based sample of 372 U.S. veterans who completed the T1 and T2 surveys. RESULTS: Early pandemic mental health was significantly and positively associated with probable ED diagnostic status. Social and health satisfaction as well as physical health pandemic impacts mediated the associations between mental health symptoms and ED diagnostic status. DISCUSSION: Findings highlight the importance of bolstering social connection, health-promoting behaviors, and access to ED treatment among veteran men and women impacted by the COVID-19 pandemic. PUBLIC SIGNIFICANCE: The COVID-19 pandemic has had a profound impact on mental health, including eating disorders (EDs). We found that early pandemic mental health symptoms were significantly associated with changes in U.S. veterans' ED diagnostic status 1 year later. Mental health symptoms increased ED diagnoses via their impact on social and health satisfaction, as well as physical health impacts of the pandemic. Findings highlight the importance of increasing social connection, health-promoting behaviors, and ED treatment access among veteran men and women, who may be particularly vulnerable to EDs, during the COVID pandemic.

The Posttraumatic Cognitions Inventory (PTCI): Psychometric evaluation in veteran men and women with trauma exposure.

The Posttraumatic Cognitions Inventory (PTCI) is a self-report measure of negative posttraumatic cognitions, which is an important construct in the development and maintenance of posttraumatic stress disorder (PTSD). Evidence for the most appropriate PTCI item and factor structure is mixed, and this measure has not been extensively studied in veterans. The present study examined the psychometric properties of the PTCI in two national samples of veteran men and women. Participants in Sample 1 (veterans from all service eras) and Sample 2 (recently separated veterans) completed the PTCI and additional measures of mental health symptoms. Confirmatory factor analyses indicated that a brief version of the PTCI (PTCI-9; 3-factor, nine-item) was a superior fit relative to other examined factor structures. Consistent with the original conceptualization of the measure, these factors were labeled: Negative cognitions about self, negative cognitions about the world, and self-blame. Scores on the PTCI-9 were differentially associated with the PTSD symptom clusters and with scores on self-report measures of external comorbidities. PTCI-9 scores were higher among individuals with trauma exposure and with a probable PTSD diagnosis. There was evidence of full (Sample 1) and partial (Sample 2) scalar invariance across men and women. Overall, the present study supports the use of the PTCI-9 as a measure of negative cognitions; however, scores may not be specific to PTSD and may represent a global negative thinking style. Even so, the PTCI-9 appears to be a suitable and abbreviated measure that could be used with veterans in research and clinical practice. (PsycInfo Database Record (c) 2023 APA, all rights reserved).

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.

Effects of Intimate Partner Violence During COVID-19 and Pandemic-Related Stress on the Mental and Physical Health of Women Veterans.

BACKGROUND: Little is known about women veterans' intimate partner violence (IPV) experiences during the COVID-19 pandemic or the impacts of pandemic-related stress on their mental and physical health. OBJECTIVES: To identify IPV experiences among women veterans prior to and during the pandemic, pandemic-related stressors, and examine their respective contributions to mental and physical health. DESIGN: National sample of women veterans drawn from a larger web-based longitudinal study. Relationships between recent IPV and pandemic-related stressors were tested with linear regressions, controlling for pre-pandemic IPV and mental and physical health symptoms, demographic, and military-related covariates. PARTICIPANTS: One hundred forty-two women veterans (Mage=58.8 years). MAIN MEASURES: We assessed IPV (CTS-2), PTSD (PCL-5), depression (CESD), anxiety (DASS-A), physical health (PHQ-15), and physical health-related quality of life (SF-12) prior to the pandemic (June 2016-December 2016/January 2017) and during the pandemic study period (March 2020-December 2020/January 2021). We assessed pandemic-related stressors (EPII) during the pandemic study period. KEY RESULTS: Over a third (38.7%) of participants experienced IPV during the pandemic study period (psychological: 35.9%, physical: 9.9%, sexual: 4.2%). Overall rates, frequency, and severity of IPV experience did not significantly differ between the pre-pandemic and pandemic study periods. Few participants tested positive for COVID-19 (4.2%); however, most participants reported experiencing pandemic-related stressors across life domains (e.g., social activities: 88%, physical health: 80.3%, emotional health: 68.3%). IPV during the pandemic and pandemic-related stressors were both associated with greater PTSD and depressive symptoms. Pandemic-related stressors were associated with worse anxiety and physical health symptoms. Neither IPV during the pandemic nor pandemic-related stressors were associated with physical health-related quality of life. CONCLUSIONS: IPV experiences during the pandemic were common among women veterans, as were pandemic-related stressors. Although IPV did not increase in the context of COVID-19, IPV experiences during the pandemic and pandemic-related stressors were linked with poorer mental and physical health.

What next for eating disorder genetics? Replacing myths with facts to sharpen our understanding.

Substantial progress has been made in the understanding of anorexia nervosa (AN) and eating disorder (ED) genetics through the efforts of large-scale collaborative consortia, yielding the first genome-wide significant loci, AN-associated genes, and insights into metabo-psychiatric underpinnings of the disorders. However, the translatability, generalizability, and reach of these insights are hampered by an overly narrow focus in our research. In particular, stereotypes, myths, assumptions and misconceptions have resulted in incomplete or incorrect understandings of ED presentations and trajectories, and exclusion of certain patient groups from our studies. In this review, we aim to counteract these historical imbalances. Taking as our starting point the Academy for Eating Disorders (AED) Truth #5 "Eating disorders affect people of all genders, ages, races, ethnicities, body shapes and weights, sexual orientations, and socioeconomic statuses", we discuss what we do and do not know about the genetic underpinnings of EDs among people in each of these groups, and suggest strategies to design more inclusive studies. In the second half of our review, we outline broad strategic goals whereby ED researchers can expand the diversity, insights, and clinical translatability of their studies.

Associations between probable eating disorders and healthcare use among post-9/11 veteran men and women.

OBJECTIVE: Healthcare use is elevated among individuals with eating disorders (EDs); however, most people with EDs do not receive ED-specific care, likely due to factors such as the cost and availability of treatment as well as stigma. U.S. military veterans historically have been understudied in ED research. We investigated healthcare use and barriers to care among recently separated veteran men and women. METHOD: In this cross-sectional study, 1494 participants completed an online or paper survey assessing ED symptoms, healthcare use, and logistical and attitudinal barriers to care. We estimated logistic regression models to investigate the association of ED status with healthcare use variables and examined gender similarities and differences in barriers to care. RESULTS: Men and women with probable EDs reported low rates of ED treatment but greater healthcare use, during military service and since separating from service, compared to veterans without probable EDs (odds ratios = 1.57-7.05). Large proportions of participants reported that they did not know where to get help for EDs and that treatment is too costly. There were few gender differences in barriers to care (Cramer's V = 0.02-0.32). CONCLUSION: Veterans reported high healthcare use but low rates of ED treatment. Findings underscore the need to increase the reach and accessibility of ED treatment in potentially vulnerable groups.

Disordered eating in sexual minority post-9/11 United States veterans.

OBJECTIVE: It is well documented that sexual minority individuals are more likely to report disordered eating (DE) than those identifying as heterosexual. Although DE is prevalent in veterans, investigation of potential disparities in DE among sexual minority veterans is limited. This study examined rates of DE in post-9/11 United States (U.S.) veterans identifying as sexual minorities and explored their association with discrimination because of marginalized identities. METHODS: A national sample of recently separated post-9/11 U.S. veterans were recruited. Women (N = 805; heterosexual [n = 656]; lesbian [n = 51]; bisexual [n = 98]) and men (N = 558; heterosexual [n = 540]; gay [n = 11]; bisexual [n = 7]) completed a survey assessing eating behaviors, mental health, and military experiences. Weighted correlational and regression analyses were conducted. Analyses in men were exploratory. RESULTS: DE was prevalent across gender and sexual orientation identity groups. Women identifying as bisexual and men identifying as gay reported higher rates of DE and consequent impairment compared to veterans who identified as heterosexual. There were no differences in DE between heterosexual and lesbian female veterans, but lesbian women reported lower DE-related impairment. Experiencing any discrimination in the military was positively related to DE. DISCUSSION: This study found evidence of disparities in DE among sexual minority U.S. military veterans. While the factors contributing to these differences, such as the role of discrimination, are not completely understood, DE is a health concern for sexual minority veterans and requires continued investigation. PUBLIC SIGNIFICANCE: Sexual minority individuals experience disparities in disordered eating; yet, this has not been explored in military veterans. This study found that disordered eating is a significant health concerns for veteran women and men, especially among those identifying as sexual minorities. More research is needed to explore why these disparities exist, such as the role of minority stress, in order to address the unique healthcare needs of these veterans.

The Affective Control Scale: Factor structure and associations with posttraumatic stress symptoms in trauma-exposed male veterans.

OBJECTIVE: Posttraumatic stress disorder (PTSD) is characterized by broad-based difficulties with emotion. However, the extent to which the disorder is associated with fear of particular emotions remains less well understood. The Affective Control Scale (ACS) is a frequently used measure of fear of emotion, but relatively little work has been done to validate this measure, particularly for use in psychiatric research. This study examined the ACS's factor structure and its associations with PTSD symptoms among trauma-exposed male veterans. METHOD: Participants (N = 347) completed online assessments, including the ACS and the PTSD Checklist for the Diagnostic and Statistical Manual of Mental Disorders, fifth edition (DSM-5). RESULTS: The data supported a bifactor structure with 1 general fear of emotion factor and 4 specific fear of emotion factors (i.e., fear of anger, fear of positive affect, fear of depressed mood, and fear of anxiety). Fear of emotion was positively associated with all 4 DSM-5 PTSD symptom clusters. After controlling for general fear of emotion, fear of particular emotion states was associated with some specific PTSD symptoms. CONCLUSION: Both general and specific fears of emotion were associated with specific PTSD symptoms in trauma-exposed veterans. Despite this, results support the use of a modified ACS total score, capturing general fear of emotion, rather than the subscale scores, capturing fear of specific emotions.

Eating disorder measures in a sample of military veterans: A focus on gender, age, and race/ethnicity.

Early detection of eating disorders (EDs) is crucial for both prevention and treatment; however, few ED measures have been validated among older adults, men, and racially/ethnically diverse individuals, who may have varying symptom presentations. We examined the psychometric quality of three self-report ED measures within a diverse sample of U.S. military veterans, a population that may have elevated rates of EDs. Participants (N = 1,187) completed the Eating Disorder Diagnostic Scale-5 (EDDS-5), the Eating Disorder Examination-Questionnaire (EDE-Q), the SCOFF (Sick, Control, One, Fat, and Food) questionnaire, and measures of associated mental health symptoms. We examined proportions of probable EDs and reliability estimates, associations among ED measures, and their relationship with mental health measures for the sample as a whole and based on age, gender, and race/ethnicity. Proportions of probable EDs ranged from 9.9% to 27.7% and were comparable for White, Black, and Latinx participants. Participants aged 40-49 had significantly higher proportions of EDs compared to other age groups, whereas participants aged ≥60 had significantly lower proportions of EDs. Participants with obesity had significantly higher proportions of probable EDs compared to participants with healthy weight or overweight. There was fair to moderate agreement between the ED measures, with varying evidence for psychometric quality across demographic subsamples. Overall, the EDDS-5 performed best in this sample and yielded estimates of probable EDs consistent with expectations. These data add to the growing body of literature on the assessment of EDs and provide insight into measures that may be most useful in research and intervention efforts.

Associations between eating disorder symptoms, employment status, and occupational functioning among female veterans.

BACKGROUND: Eating disorders (EDs) have been shown to negatively impact occupational functioning and may be associated with employment status. Findings have been inconsistent, and depression may mediate this relation. Further, prior research focuses mainly on binge eating disorder's (BED) impact on occupational functioning. We assessed the association between transdiagnostic ED symptoms and occupational functioning and employment status among female veterans, who tend to have high rates of EDs and unemployment but who remain understudied. METHOD: Participants were 198 female veterans (Mage = 54.09) in the New England region who participated in a larger study. They completed a mailed survey including the Eating Disorder Diagnostic Scale, Center for Epidemiologic Studies-Depression Scale, employment status (employed vs. unemployed and out of the workforce), and the Inventory of Psychosocial Functioning to assess occupational functioning. RESULTS: ED symptoms were not significantly related to employment status but were negatively associated with occupational functioning when controlling for body mass index. Depressive symptoms mediated the associations between ED symptoms and both being out of the workforce and occupational functioning, respectively. DISCUSSION: Higher levels of ED symptoms were associated with worse occupational functioning in a female veteran sample. Further, comorbid depressive symptoms may be an important treatment target when addressing occupational health in women experiencing ED symptoms.

The impact of comorbid posttraumatic stress disorder on eating disorder treatment outcomes: Investigating the unified treatment model.

PURPOSE: Many women with eating disorders (EDs) have comorbid posttraumatic stress disorder (PTSD). However, there have been few studies on how comorbid PTSD may impact ED treatment outcomes. METHOD: Participants were 2,809 patients from residential ED treatment facilities who were treated using the Unified Treatment Model (UTM). We investigated whether PTSD diagnosis at admission was associated with changes in Eating Disorder Examination-Questionnaire (EDE-Q) scores, binge eating, self-induced vomiting, and restriction, across three time points, as well as clinically significant improvement and treatment drop-out. RESULTS: Using latent growth models, with time modeled as a second-order polynomial, we found that EDE-Q scores and behavioral symptoms decreased from admission to discharge, but increased from discharge to 6-month follow-up. PTSD diagnosis was associated with higher baseline EDE-Q scores and restriction, and lower binge-eating frequency. PTSD diagnosis was not associated with symptom change over time, treatment dropout, or clinically significant change. DISCUSSION: Although PTSD diagnoses were associated with higher ED symptom levels at admission, PTSD was not associated with worse treatment outcomes, suggesting the UTM is a promising treatment for patients with and without PTSD. Future studies should investigate the impact of ED treatment on PTSD symptoms in order to determine the need for integrated treatments for these comorbid conditions.

Emotion regulation and the association between PTSD, diet, and exercise: a longitudinal evaluation among US military veterans.

Background: Posttraumatic stress disorder (PTSD) is associated with premature onset of chronic health conditions such as cardiovascular disease. Diet and exercise are behavioural contributors to physical health, and research suggests they are influenced by psychiatric symptoms, including PTSD. Objectives: The aim of this study was to examine longitudinal associations between PTSD and exercise and diet quality and to test if emotion regulation strategies contribute to the link between PTSD and these health behaviours. Method: A representative sample of US military veterans (n = 860 at Time 1, n = 503 at Time 2, mean age = 63 years, 91.5% male) were assessed twice over the course of approximately three years. Results: Mediation models revealed that the association between baseline PTSD symptom severity and subsequent diet quality was mediated by emotion suppression (measured at Time 2; indirect B = -.03; 95% CI: -.059 to -.002). Trauma exposure also directly predicted diet quality (B = -.31; p = .003). There were no significant direct or indirect associations between PTSD severity or trauma exposure and exercise engagement. Conclusions: These results suggest that PTSD symptoms are associated with worse diet quality and that the consumption of unhealthy food may be driven by efforts to suppress emotion. This carries implications for understanding and treating medical comorbidities among those with traumatic stress.

Antecedentes: El trastorno de estrés postraumático (TEPT) está asociado con el inicio prematuro de condiciones crónicas de salud, como la enfermedad cardiovascular. La dieta y el ejercicio son contribuyentes conductuales para la salud física y las investigaciones sugieren que están influenciados por los síntomas psiquiátricos, incluyendo al TEPT.Objetivos: El objetivo de este estudio fue el de evaluar las asociaciones longitudinales entre el TEPT y el ejercicio y la calidad de la dieta; asimismo, evaluar si las estrategias de regulación emocional contribuyen al vínculo entre el TEPT y estas conductas de salud.Métodos: Se evaluó a una muestra representativa de veteranos de guerra estadounidenses (n = 860 en el Tiempo 1, n = 503 en el Tiempo 2, edad promedio = 63 años, 91,5% varones) en dos oportunidades en un periodo de tres años.Resultados: Los modelos de mediación mostraron que la asociación entre la severidad de los síntomas del TEPT de base y la calidad subsecuente de la dieta estaba mediada por la supresión de emociones (medidos en el Tiempo 2; B indirecta = −.03; 95% CI: − .059 to − .002). La exposición al trauma también predijo la calidad de la dieta de manera directa (B = = −.31; p = .003). No se encontraron asociaciones, directas o indirectas, entre la severidad del TEPT o la exposición al trauma con el compromiso con el ejercicio.Conclusiones: Estos resultados sugieren que los síntomas del TEPT están asociados a una peor calidad de la dieta y que el consumo de alimentos no saludables puede estar impulsado por esfuerzos para suprimir las emociones. Esto conlleva a implicaciones para comprender y tratar las comorbilidades médicas entre aquellos con estrés traumático.

Latent Class Analysis of Self-directed Violence and Indirect Self-harm Behaviors: Gender Differences and Associations With Mental Health Symptoms.

OBJECTIVE: This study aimed to (1) examine whether the latent class structure of individuals engaging in self-directed violence and indirect self-harm behaviors (eg, substance use, disordered eating) varied by gender in a sample of US veterans, and (2) test the associations of posttraumatic stress disorder (PTSD) and depressive symptoms with the resulting classes. STUDY DESIGN: Cross-sectional data from 3581 veterans, ages 18-50 (51.9% identified as women) were analyzed. Veterans self-reported histories of self-directed violence, substance use, and disordered eating. Latent class analysis and latent class regression were used to explore class structure by gender and examine association of class membership with PTSD and depressive symptoms. RESULTS: A 4-class model was supported in the sample. Class 1 (20.0%) was characterized by substance use and self-directed violent thoughts and behaviors. Class 2 (8.3%) was characterized by substance use, disordered eating, and self-directed violent thoughts and behaviors. Class 3 (12.6%) was distinguished by indirect self-harm behaviors (substance use and disordered eating). Class 4 (59.6%) reflected low likelihood of behavioral dysregulation. Classes were partially invariant across gender; endorsement of substance use behaviors was generally higher for men in each class. Comorbid clinically significant depressive and PTSD symptoms were associated with the class characterized by highest behavioral dysregulation. CONCLUSIONS: Self-directed violent thoughts and behaviors present comorbidly with indirect self-harm in men and women veterans, although patterns of indirect self-harm behaviors differ slightly by gender. Such comorbidity may be associated with more severe presentations of psychiatric concerns.

Posttraumatic stress disorder and eating disorders: maintaining mechanisms and treatment targets.

Many individuals with lifetime histories of eating disorders (EDs) report exposure to interpersonal trauma and posttraumatic stress disorder (PTSD). However, this relationship is not well-understood, and there are no established, evidence-based therapies for the concurrent treatment of EDs and PTSD. This review focuses on studies of the mechanisms associating trauma exposure and/or PTSD with EDs. Possible mechanisms of the trauma-ED association identified from the literature include self-criticism, low self-worth, guilt, shame, depression, anxiety, emotion dysregulation, anger, and impulsivity/compulsivity. ED behaviors may be used as coping strategies to manage PTSD symptoms and negative affect. Avoidance of hyperarousal symptoms by engaging in binge eating, purging, and/or restriction may serve to maintain both the ED as well as the PTSD. Given the evidence of the bidirectional relationship between EDs and PTSD, we describe an integrated cognitive behavioral theory that may account for the persistence of comorbid PTSD and EDs. The integrated model is based on the theoretical models that underpin existing evidence-based treatments for PTSD and ED and incorporates many of the potential mechanisms highlighted to date. The primary aim of the model is to identify potential treatment targets as well as elucidate future directions for research.

Examining the Association between Trauma Exposure and Work-Related Outcomes in Women Veterans.

Women veterans have high rates of trauma exposure, including military sexual trauma (MST), which are associated with numerous health and psychosocial consequences. However, associations between trauma history and work-related outcomes are less well-characterized. We examined whether military-related and non-military trauma types were associated with work-related outcomes and whether posttraumatic stress disorder (PTSD) and depression symptoms mediated these associations. A total of 369 women veterans completed up to two mailed surveys, 12 months apart, assessing trauma exposure, depression and PTSD symptoms, occupational functioning, and employment status (unemployed, out of the workforce, employed). Participants reported high rates of trauma exposure. Nearly half (47.5%) were out of the workforce. Military-related trauma, military sexual assault, and adult sexual assault were associated with worse occupational functioning. Only PTSD symptoms mediated associations between trauma types and occupational functioning. No trauma types were significantly directly associated with employment status; however, PTSD and depression symptoms mediated associations between trauma types and being out of the workforce. Findings can inform screening for military trauma exposures, mental health, and work-related needs among women veterans.
