An Executive Functioning Composite Does Not Moderate the Relationship Between Combat Exposure and Posttraumatic Stress Disorder Symptom Clusters.

OBJECTIVE: Posttraumatic stress disorder (PTSD) is prevalent among U.S. combat Veterans, and associated with poor health and wellbeing. As combat experiences are likely to significantly modify self-, other-, and society-oriented cognitions and heighten risk for PTSD, examination of related cognitive processes may yield new treatment strategies. The cognitive model of PTSD suggests that persistent threat perceptions contribute to symptom worsening. Thus, cognitive processes of shifting perspectives or generating novel interpretations may be particularly relevant to lessen PTSD symptoms. This cross-sectional study examined executive functioning as a moderator to the relationship between combat exposure and PTSD symptom clusters among post-9/11 Veterans. METHOD: Data from 168 Veterans were drawn from a larger study examining post-deployment mental health and cognitive function. An executive functioning composite derived from Wisconsin Card Sorting Test Perseveration Errors, WAIS-III Similarities, Trail Making Test B, and Stroop Color-Word Inhibition scores was computed. Path analysis was used to test the moderation model. RESULTS: After accounting for age, sex, and estimated premorbid functioning, results indicated that combat exposure was associated with all symptom clusters on the PTSD Checklist-Military. Executive functioning was not significantly associated with the PTSD symptom clusters and did not moderate the relationship between combat exposure and any of the PTSD symptom clusters. CONCLUSIONS: Combat exposure is an important dimension of risk related to PTSD in Veterans that warrants regular screening. Moderation by executive functioning was not observed despite theoretical support. Future work could test methodological and sampling reasons for this finding to determine if theoretical adjustment is necessary.

Exposure to combat experiences: PTSD, somatization and aggression amongst combat and non-combat veterans.

To this date, the prevalence of posttraumatic stress disorder (PTSD) and associated psychological symptom profiles amongst non-combatant community-based veterans in Israel has not been studied. Data were analysed from a web-based survey of veterans via a market research platform during September 2021 and included 522 non-combat (e.g. intelligence, office-based or education corps) veterans and 534 combat (e.g. front-line infantry) veterans. The survey assessed PTSD, depression, anxiety and somatic symptoms in addition to the prevalence of self-reported aggression. A two-way multivariate analysis of covariance indicated that higher PTSD and somatic symptoms were prevalent for those exposed to combat experiences even when not in a combatant role. A logistic regression indicated that of those who did not self-define as aggressive prior to service, those exposed to combat were three times more likely to be aggressive following their service than veterans not exposed to combat. This effect was not demonstrated for combat soldiers compared to non-combat soldiers. Results indicate that mental health outreach would be better targeted towards those who have been exposed to combat-type experiences during their service even in non-combat units. The current study highlights the effect of combat exposure on secondary PTSD symptoms; aggression and somatization.

Does Prior Civilian Trauma Moderate the Relationship Between Combat Trauma and Post-deployment Mental Health Symptoms?

In addition to combat trauma, childhood and adult non-military, interpersonal trauma exposures have been linked to a range of psychiatric symptoms (e.g., alcohol use problems, posttraumatic stress disorder [PTSD], depression symptoms) in veterans. However, few studies simultaneously explore the associations between these civilian and combat trauma types and mental health outcomes. Using a sample of combat-exposed veterans who were previously deployed to Iraq and Afghanistan (N = 302), this study sought to (a) understand the independent associations of civilian interpersonal trauma (i.e., childhood trauma and non-military adult trauma) and combat-related trauma with post-deployment alcohol use, PTSD symptoms, and depressive symptoms, respectively and (b) to examine the interactive effects of trauma type to test whether childhood and non-military adult trauma moderate the association of combat trauma with these outcomes. A path analytic framework was used to allow for the simultaneous prediction of these associations. In the final model non-military adult trauma and combat trauma were found to be significantly associated with PTSD symptoms and depression symptoms, but not average amount of drinks consumed per drinking day. Childhood trauma was not associated with any outcomes (i.e., PTSD symptoms, depression symptoms, average amount of drinks consumed per day). Only combat trauma was significantly associated with average amount of drinks consumed per day. Results underscore the importance of assessing multiple trauma types and considering trauma as a non-specific risk factor, as different trauma types may differentially predict various mental health outcomes other than PTSD. Further, results highlight the noteworthiness of considering co-occurring outcomes within the veteran community. Limitations, future directions, and implications of diversity are discussed.

Combat Exposure and Risk of Suicide Attempt Among Danish Army Military Personnel.

Objective: The aim of this study was to estimate the association between self-reported perceived danger during deployment, measured as combat exposure or witnessing the consequences of war, and post-deployment suicide attempts among military personnel. Furthermore, the effect of post-deployment symptoms of posttraumatic stress disorder (PTSD) and/or depression on the risk of suicide attempts was also evaluated.Methods: This observational cohort study included Danish Army military personnel who returned from deployment in international missions from 1998 to 2016 and had completed a post-deployment questionnaire. Perceived exposure to danger was ascertained by self-report. Data on suicide attempt were retrieved from national registers. Adjusted Cox regression analyses were used to evaluate if military personnel indicating high level of combat exposure were more likely to have attempted suicides post-deployment than military personnel with lower levels of combat exposure.Results: Eighty-three suicide attempts were registered after homecoming among 12,218 military personnel. Perceived higher exposure to combat was associated with the risk of suicide attempt (hazard ratio = 1.08; 95% CI, 1.01-1.16). Furthermore, the association between combat exposure and suicide attempt was fully mediated by post-deployment symptoms of PTSD and/or depression. No association was found between witnessing consequences of war and the risk of post-deployment suicide attempt.Conclusions: This nationwide study found that combat exposure was associated with an increased risk of suicide attempt among military personnel. This association was, however, fully mediated by mental disorders (PTSD and/or depression). These findings suggest that better psychological follow-up of military personnel identified as having PTSD and/or depression may be warranted.

Drinking to Cope with Posttraumatic Stress: A Nationally Representative Study of Men with and without Military Combat Experience.

OBJECTIVE: Posttraumatic stress disorder (PTSD) and hazardous alcohol use are prevalent among trauma survivors. Despite higher rates of both PTSD and hazardous alcohol use among military combat veterans than civilians, scant research has examined whether military combat experience is associated with drinking alcohol to cope with PTSD symptoms. This study tested the hypothesis that compared to trauma-exposed men without combat experience, men with military combat experience would be more likely to endorse drinking alcohol to cope with their PTSD symptoms. Methods: Interview data from N = 11,474 men who reported at least one lifetime traumatic experience were drawn from the National Epidemiologic Survey on Alcohol and Related Conditions (NESARC), a face-to-face interview study that recruited a nationally representative sample of adults living in the United States between 2004 and 2005. Results: Among men endorsing lifetime trauma exposure, men with military combat experience (n = 1,386) were more likely than men without combat experience (n = 10,088) to report drinking alcohol to cope (7.22 vs. 2.61% in unweighted analyses, 6.46 vs. 2.37% in weighted analyses). Total number of lifetime trauma types, lifetime PTSD severity, and lifetime alcohol abuse/dependence were significantly associated with drinking to cope in bivariate and multivariate analyses. Military combat experience was significantly associated with drinking to cope in multivariate analyses adjusting for lifetime PTSD diagnosis. Military combat experience was not significantly associated with drinking to cope in multivariate analyses adjusting for lifetime PTSD symptom count. Conclusions: Although military combat experience was significantly associated with drinking to cope in bivariate analyses, multivariate analyses yielded mixed findings: combat experience was significantly associated with drinking to cope in models adjusting for PTSD diagnosis, but not in models adjusting for PTSD symptom count. Findings highlight the importance of assessing and targeting PTSD symptom-related alcohol use, even in the absence of alcohol abuse/dependence. Results from this preliminary study could inform future research on drinking to cope with PTSD symptoms among military combat veterans and other trauma survivors.

Can military trauma promote psychological growth in combat veterans? Results from the national health and resilience in veterans study.

BACKGROUND: Military combat trauma is often associated with negative outcomes, including high rates of posttraumatic stress disorder (PTSD). Less is known, however, about whether military combat trauma may foster posttraumatic growth (PTG), which has been observed in relation to other trauma types, in representative samples of veterans. METHODS: We analyzed data from veterans who participated in the National Health and Resilience in veterans Study who reported a military-related trauma (n = 210). Participants completed measures of trauma history, combat exposure, PTSD symptoms, PTG, functioning, and quality of life (QOL). Bivariate correlations, regression analyses, analyses of covariance, and fit of linear and quadratic functions were used to examine relationships between PTSD symptom clusters, PTG and its subdomains, and functioning. RESULTS: Number of deployments (ß=0.23) and lifetime PTSD symptom severity (ß=0.19), particularly re-experiencing symptoms (ß=0.37), were independently associated with greater PTG. An inverted-U-shaped quadratic function provided the best fit for the relationship between PTSD symptoms and PTG (R2 =0.22). Greater PTG was associated with greater mental functioning (ß=0.15) and QOL (ß=0.24). LIMITATIONS: The inability to make casual inferences in this cross-sectional study; possible bias related to self-report measures; and the lengthy time period between index trauma and assessment of PTSD and PTG. CONCLUSIONS: PTG is relatively common among combat veterans, particularly among those with PTSD, and is associated with better mental functioning and QOL. Positive psychology interventions to bolster PTG may help promote functional outcomes in this population.

Longitudinal Relationship of Combat Exposure With Mental Health Diagnoses in the Military Health System.

INTRODUCTION: Combat deployment is associated with mental and physical health disorders and functional impairment. Mental health (MH) diagnoses such as adjustment and anxiety disorders have received little research attention but may reflect important postdeployment sequelae. The purpose of this study was to investigate the association of combat exposure with the acquisition of a wide range of mental health diagnoses over 2 years. MATERIALS AND METHODS: This retrospective longitudinal study utilized multiple administrative Military Health System datasets compiled for all individuals who entered active duty in the U.S. Army from FY2005 to FY2011. A total eligible cohort of 289,922 Service members was stratified into three mutually exclusive groups according to their deployment status after 2 years in service: Deployed, Combat-Exposed; Deployed, Not-Combat-Exposed; and Not Deployed. Outcomes of interest were new mental health diagnoses grouped into six categories-posttraumatic stress disorder, anxiety, adjustment, mood, substance use disorders, and any MH diagnosis. Survival analyses over 2 years were conducted and adjusted hazard ratios were calculated. RESULTS: Combat exposure in the first 2 years of military service was associated with significantly higher rates of a wide range of mental health diagnoses over a two-year follow-up period, compared with deployment with no combat exposure and no deployment. Adjusted cumulative failure proportions demonstrated that approximately a third of the Combat-Exposed group, a quarter of the Not-Combat-Exposed, and a fifth of the Not Deployed groups received a MH diagnosis over 2 years. For all groups, cumulative failure proportions and incidence rates were highest for adjustment disorder and lowest for posttraumatic stress disorder diagnoses. CONCLUSIONS: Researchers and providers should be alerted to the impact of combat exposure and the wide range of MH conditions and diagnoses that may represent important postdeployment sequelae.

Military Combat, Posttraumatic Stress Disorder, and the Course of Alcohol Use Disorders in a Cohort of Australian Vietnam War Veterans.

The present study examined the course of diagnosed alcohol use disorders (AUDs) in a cohort of Australian veterans of the Vietnam War (N = 388) who were assessed 22 and 36 years after returning home. Standardized interviews provided data on AUDs, posttraumatic stress disorder (PTSD), other psychiatric diagnoses, and combat exposure. Overall, 148 veterans (38.1%) had no history of alcohol-related diagnoses, 151 veterans (38.9%) had a past AUD diagnosis that was not current at the second assessment point, and 89 veterans (22.9%) had a current AUD diagnosis at the second assessment. Less education, lower intelligence test scores, and misconduct were individual risk factors for AUDs, as were first-interview diagnoses of PTSD, antisocial personality disorder, generalized anxiety, and dysthymia, but not depression; these variables were all nonsignificant after controlling for combat exposure and PTSD. Multinomial regression was used to assess the relative contributions of combat exposure and PTSD to the course of AUDs. Combat exposure and PTSD had different patterns of association with AUDs whereby combat exposure, but not PTSD, was associated with a history of AUDs, odds ratio (OR) = 1.02, but not with current AUDs, whereas PTSD, but not combat exposure, was associated with current AUDs, OR = 3.37. Current numbing and avoidance symptoms were associated with current AUDs, OR = 4.48. The results do not support a mutual maintenance model of PTSD and AUDs but are consistent with a self-medication model, which suggests treatment for PTSD may have beneficial effects on AUDs.

UK military women: mental health, military service and occupational adjustment.

BACKGROUND: Recently, the UK Armed Forces have revised the ground close combat role to include women. AIMS: To assess the potential mental health impact of this initiative we examined gender differences in deployment patterns, work strain, occupational factors, mental health, alcohol use and help-seeking following operational deployment. METHODS: The study was a secondary analysis of self-report survey data; 8799 men (88%) and 1185 women (12%) provided data. A sub-sample (47%, n = 4659) provided data concerning post-deployment help-seeking. The latter consisted of 408 women (8.8%) and 4251 men (91%). RESULTS: With the exception of alcohol misuse, which was significantly lower for women, women reported significantly more common mental disorder symptoms, subjective depression and self-harm. Women were significantly more likely to seek help from healthcare providers. Men were significantly more likely to have deployed operationally and for longer cumulative periods. Subjective work strain, but not job control, was significantly lower for women whose military careers were significantly shorter. Post-traumatic stress disorder (PTSD) symptom intensity was similar to men. CONCLUSIONS: With the exception of PTSD and alcohol misuse, UK military women experience more mental health-related problems than military men. This finding was not related to the more arduous aspects of military service as women served for shorter times, deployed less and for shorter cumulative periods and were less likely to report work-related stress.

Impact of Pre-Existing Migraine and Other Co-Morbid or Co-Occurring Conditions on Presentation and Clinical Course Following Deployment-Related Concussion.

OBJECTIVE: To describe the clinical presentation and early clinical course of a sample of deployed U.S. military service members following concussion, underscoring the impact of pre-existing migraine and other co-occurring conditions. It is important to obtain a comprehensive clinical history to identify evidence of underlying migraine and other health conditions which may contribute to an individual's presenting symptoms influencing early management and outcomes following concussion. Early outcome measures assessed include headache treatment response and fitness for return to duty. BACKGROUND: Acute concussion is reported to result in an array of somatic, cognitive, and behavioral symptoms. It is well established that these symptoms are not specific for concussion and may result from exacerbation of pre-existing or underlying medical conditions and factors. Although most symptoms attributable to concussion resolve within days to weeks, there is evidence that persistent symptoms beyond that specific recovery time may be attributable to factors other than concussion. Military populations are at risk for a number of recognized co-morbid and co-occurring conditions, as well as special situational and psychosocial factors which may influence symptoms and clinical course following concussion. In addition, combat-related concussion frequently occurs in the setting of a blast or military vehicle accidents thus causing concurrent injuries where musculoskeletal injuries may contribute to the clinical presentation. The resultant acute stress reaction, secondary to the traumatic experience associated with concussion, may also cause or aggravate underlying psychological co-morbidities that may influence presenting symptoms. Prior studies identified co-morbidities associated with chronic post-concussive syndrome, which we find are also present during the early phase following deployment-related concussion, thereby influencing presentation and impacting recovery. This retrospective chart review was intended to demonstrate the presence and potential impact of co-morbid and co-occurring conditions contributing to symptoms following concussion, especially migraine due to its high prevalence among post-traumatic headaches. METHODS: Retrospective chart review was performed by the treating neurologist of 40 service members following concussion in the deployed environment. Clinical symptoms and co-morbid and co-occurring conditions including evidence of pre-existing migraine identified during comprehensive neurologic evaluations were collected. Both pre-deployment/pre-traumatic and post-traumatic headache features supporting migraine and early instituted headache management and treatment response are described. Rates of return to duty in this sample were also tabulated. RESULTS: Headaches were the most frequently reported acute symptom following concussion in this deployed service member population (38/40 patients [98%]), followed by insomnia, tinnitus, impaired concentration, nausea, dizziness, anxiety, impaired balance, depression, and hearing loss. Co-occurring acute injuries, acute stress reaction, and recent onset medication overuse were the most frequent co-occurring conditions identified by the treating neurologist as potentially contributing to the service member's presentation. Chronic co-morbidities identified included chronic headache, anxiety/depression, insomnia, and post-traumatic stress disorder. Service members with 3 or more identified co-morbidities or co-occurring conditions were more likely to require evacuation from theater. Pre-deployment headaches were reported by 25/40 [63%] service members, with 5/40 [12.5%] reporting known prior personal history of migraine. Of those reporting pre-deployment headaches, 21/25 [84%] described migraine features and/or triggers, though most [(15/25) 60%] reported as infrequent. Daily post-traumatic headaches were frequent (26/38 [68%]) and associated with typical migraine features and/or triggers. Of those treated with triptans (16/40 patient [42%]), most (12/16 patient [75%]) showed positive treatment response. CONCLUSIONS: Concussion in the deployed settings does not occur in isolation, with co-morbid and co-occurring conditions being common. Presence of multiple co-morbidities appears to influence clinical course and overall recovery. Post-traumatic headaches are often phenotypically fully consistent with migraine, and appear related to pre-existing migraine if supported by detailed pre-deployment headache history suggesting same. Careful and comprehensive history taking and evaluation is invaluable in identifying associated conditions including migraine, potentially helping clinicians with more accurate symptom attribution, diagnoses, and improved clinical management following acute concussion.

Baseline Cognitive Performance and Treatment Outcomes From Cognitive-Behavioral Therapies for Posttraumatic Stress Disorder: A Naturalistic Study.

OBJECTIVE: Approximately 5%-20% of U.S. troops returning from Iraq and Afghanistan have posttraumatic stress disorder (PTSD), and another 11%-23% have traumatic brain injury (TBI). Cognitive-behavioral therapies (CBTs) are empirically validated treatment strategies for PTSD. However, cognitive limitations may interfere with an individual's ability to adhere to as well as benefit from such therapies. Comorbid TBI has not been systematically taken into consideration in PTSD outcome research or in treatment planning guidance. The authors hypothesized that poorer pretreatment cognitive abilities would be associated with poorer treatment outcomes from CBTs for PTSD. METHODS: This study was designed as a naturalistic examination of treatment as usual in an outpatient clinic that provides manualized CBTs for PTSD to military service members and veterans. Participants were 23 veterans, aged 18-50 years, with combat-related PTSD and a symptom duration of more than 1 year. Of these, 16 participants had mild TBI (mTBI). Predictor variables were well-normed objective tests of cognitive ability measured at baseline. Outcome variables were individual slopes of change of the PTSD Checklist for DSM-5 (PCL-5) and the Clinician-Administered PTSD Scale for DSM-5 (CAPS-5) over weeks of treatment, and of pretreatment-to-posttreatment change in PCL-5 and CAPS-5 (ΔPCL-5 and ΔCAPS-5, respectively). RESULTS: Contrary to prediction, neither pretreatment cognitive performance nor the presence of comorbid mTBI predicted poorer response to CBTs for PTSD. CONCLUSIONS: These results discourage any notion of excluding patients with PTSD and poorer cognitive ability from CBTs.

Clinical Correlates of Dream Enactment Behaviors in Previously Deployed OEF/OIF/OND Veterans: An Exploratory Analysis.

OBJECTIVE: Veterans with posttraumatic stress disorder (PTSD) frequently report dream enactment behavior (DEB). Although DEBs are associated with PTSD symptoms, their relationship with other sleep disorders, including REM behavior disorder, warrants reexamination of their clinical correlates. METHODS: The investigators used a cross-sectional, exploratory analysis to compare demographic and clinical characteristics of veterans endorsing regularly occurring DEB compared with those endorsing no or infrequent DEB. The participants comprised a convenience sample of servicemembers who were previously deployed to Operation Enduring Freedom/Operation Iraqi Freedom/Operation New Dawn (OEF/OIF/OND) and enrolled in an ongoing cohort study. RESULTS: Of the 78 eligible participants, 19 (24.4%) endorsed DEBs occurring at least once per week in the past month. Compared with participants who reported no or infrequent DEBs, participants with regularly occurring DEBs had poorer sleep quality, greater PTSD severity, a higher number of reported mild traumatic brain injuries (mTBI) with loss of consciousness, and a higher likelihood of being diagnosed with sleep disorders. After adjustment for global sleep quality, a significant association persisted between DEBs and the number of mTBI with loss of consciousness but not between DEBs and the severity of PTSD symptoms. CONCLUSIONS: These results suggest that mTBI may disrupt neural circuits regulating sleep among OIF/OEF/OND veterans. Prospective, polysomnographic assessment of muscle tone and behavioral events during REM sleep is needed to characterize the physiology of DEBs in this population.

The Buffering Effect of Relationships on Combat Exposure, Military Performance, and Mental Health of U.S. Military Soldiers: A Vantage Point for CFTs.

This study examined the role of cumulative combat experiences with regard to military performance and conduct and mental health among a sample of young soldiers from the Army STARRS dataset (N = 5,283). Higher levels of cumulative combat experiences were directly related to poorer performance and conduct and a greater likelihood of anxiety, depression, and post-traumatic stress disorder (PTSD). Military performance and conduct served as a linking mechanism between combat experiences and mental health. Using moderated mediation structural equation modeling, relationship disruptions were found to exacerbate the adverse effects of combat experiences; conversely, unit cohesion buffered the impact of combat experiences. Implications for military helping professionals include identifying leverage points for intervention, particularly strengthening the social connections of service members within and outside the military.

Stenotrophomonas maltophilia infections: Clinical characteristics in a military trauma population.

Stenotrophomonas maltophilia is a pathogen with unique resistance patterns. We assessed 70 combat casualties with S. maltophilia clinical isolates to examine its role as a nosocomial pathogen in critically-ill trauma patients. Incidence density was 0.36 S. maltophilia infections per 100 patient-days (95% CI: 0.29-0.44). Patients predominantly had blast trauma (97%) and were critically injured (injury severity score [ISS] >25; 80%). Restricting to patients with ISS >15, 50 patients with S. maltophilia infections were compared to 441 patients with infections attributed to other gram-negative bacilli. Patients with S. maltophilia infections had significantly more operating room visits prior to isolation, traumatic or early surgical amputations, longer hospitalization (median 71 vs 47 days), and higher overall mortality (10% vs 2%; P = 0.01). Initial and serial (≥7 days between initial and subsequent isolation) S. maltophilia isolates had high susceptibility to trimethoprim-sulfamethoxazole and minocycline. Evaluation of newer agents awaiting CLSI breakpoints, including moxifloxacin, showed promising results.

Posttraumatic Stress Disorder Severity and Insomnia-Related Sleep Disturbances: Longitudinal Associations in a Large, Gender-Balanced Cohort of Combat-Exposed Veterans.

Few studies have investigated the range and severity of insomnia-related sleep complaints among veterans with posttraumatic stress disorder (PTSD), and the temporal association between insomnia and PTSD severity has yet to be examined. To examine these associations, a large, gender-balanced cohort of veterans (N = 1,649) of the Iraq and Afghanistan conflicts participated in longitudinal assessments of PTSD and insomnia-related symptoms over a period of 2.5 years following enrollment (range: 2-4 years). Data were obtained from multiple sources, including interviews, self-report assessments, and electronic medical record data. Three-fourths (74.0%) of veterans with PTSD diagnoses at Time 1 (T1) reported insomnia-related sleep difficulties on at least half the nights during the past 30 days, and one-third of participants had received a prescription for a sedative-hypnotic drug in the past year. Veterans without PTSD had fewer sleep problems overall, although the prevalence of sleep problems was high among all study participants. In longitudinal, cross-lagged panel models, the frequency of sleep problems at T1 independently predicted increases in PTSD severity at Time 2 (T2), B = 0.27, p < .001, after controlling for gender and relevant comorbidities. Conversely, T1 PTSD severity was associated with increasing sleep complaints at T2 but to a lesser degree, B = 0.04, p < .001. Moderately high rates of sedative-hypnotic use were seen in veterans with PTSD, with more frequent use in women compared to men (40.4% vs. 35.0%). Sleep complaints were highly prevalent overall and highlight the need for increased clinical focus on this area.

Spanish Abstracts by Asociación Chilena de Estrés Traumático (ACET) Gravedad del TEPT y Trastornos del Sueño Relacionados con el Insomnio: Asociaciones Longitudinales en una gran Cohorte, Balanceados por Género. de Veteranos Expuestos al Combate SUEÑO, INSOMNIO Y SEVERIDAD DE TEPT Pocos estudios han investigado el rango y la gravedad de las quejas del sueño relacionadas con el insomnio entre veteranos con trastorno de estrés postraumático (TEPT) y la asociación temporal entre el insomnio y la severidad del TEPT aún no se han examinado. Para examinar estas asociaciones, una gran cohorte de veteranos (N = 1,649) de los conflictos de Irak y Afganistán, balanceados por género, participaron en evaluaciones longitudinales de TEPT y síntomas relacionados con el insomnio durante un período de 2.5 años posteriores a la inscripción (rango: 2-4 años). Los datos se obtuvieron de múltiples fuentes, incluyendo entrevistas, autoevaluaciones y datos de registros médicos electrónicos. Tres cuartos (74.0%) de los veteranos con diagnóstico de TEPT en el tiempo 1 (T1) informaron dificultades de sueño relacionadas con el insomnio en al menos la mitad de las noches durante los últimos 30 días, y un tercio de los participantes habían recibido una prescripción de un fármaco sedante-hipnótico en el último año. Los veteranos sin TEPT tenían menos problemas de sueño en general, aunque la prevalencia de problemas de sueño fue alta entre todos los participantes del estudio. En los modelos longitudinales de panel con retardo cruzado, la frecuencia de los problemas de sueño en T1 predijeron independientemente aumentos en la severidad del TEPT en el Tiempo 2 (T2), B = 0.27, p <.001, después controlar por género y comorbilidades relevantes. Por el contrario, la gravedad del TEPT en T1 se asoció con un aumento de las quejas de sueño en T2 pero en menor grado, B = 0.04, p <.001. Se observaron tasas moderadamente altas de uso de hipnóticos-sedativos en veteranos con TEPT, con un uso más frecuente en mujeres comparadas con hombres (40.4% vs. 35.0%). En general las quejas de sueño fueron altamente prevalentes y destacan la necesidad de una mayor focalización clínica en esta área.

Typologies of Combat Exposure and Their Effects on Posttraumatic Stress Disorder and Depression Symptoms.

The present study identified distinct classes of U.S. military service members based on their combat experiences and examined mental health outcomes and longitudinal growth curves of posttraumatic stress disorder (PTSD) and depression symptoms associated with each class. Participants were 551 active duty service members who screened positive for PTSD and/or depression based on DSM-IV-TR criteria. All participants completed the Combat Experiences Scale at baseline as well as PTSD and depression measures at baseline and at 3-, 6-, and 12-month follow-ups. A latent class analysis identified four classes of service members based on their combat experiences: limited exposure, medical exposure, unit exposure, and personal exposure. Service members in the personal exposure class were characterized by a distinct mental health profile: They reported a higher level of PTSD symptoms at baseline and a higher prevalence of traumatic brain injury and PTSD diagnoses during the course of the study. The limited exposure class was more likely to receive diagnoses of depression and adjustment disorders. All classes except the medical exposure class demonstrated a slight decrease in PTSD and depression symptoms over time. However, participants in the limited exposure class had a larger decrease in PTSD and depression symptoms earlier in care but did not demonstrate superior long-term symptom improvements at 12 months compared to the other groups. These results inform PTSD development models and have implications for the screening and clinical management of combat-exposed service members.

Spanish Abstracts by Asociación Chilena de Estrés Traumático (ACET) Tipologías de Exposición a Combate y sus Efectos en el Trastorno de Estrés Postraumático y Síntomas Depresivos. EXPERIENCIAS TRAUMÁTICAS DE COMBATE, TEPT Y DEPRESIÓN El presente estudio identificó clases distintivas de miembros del servicio militar de los EEUU basados en sus experiencias de combate y examinó los resultados en salud mental y las curvas de crecimiento longitudinal del Trastorno de Estrés Postraumático (TEPT) y síntomas depresivos asociados con cada clase. Los participantes fueron 551 miembros en servicio activo que resultaron positivo para TEPT y/o depresión basado en los criterios DSM-IV-R. Todos los participantes completaron la Escala de Experiencias de Combate así como también medidas de TEPT y Depresión, al inicio y a los 3, 6 y 12 meses de seguimiento. Un análisis de grupos latente identificó cuatro clases de miembros del servicio basados en sus experiencias de combate: exposición limitada, exposición médica, exposición de la unidad, y exposición personal. Los miembros del servicio en el grupo de exposición personal se caracterizaron por un perfil distintivo de salud mental: Ellos reportaron, al inicio, niveles más altos de síntomas de TEPT y prevalencias más altas de diagnósticos de lesión traumática cerebral y TEPT durante el curso del estudio. El grupo de exposición limitada tuvo mayor probabilidad de recibir los diagnósticos de depresión y trastorno de adaptación. Todos los grupos, excepto el grupo de exposición médica, demostraron una leve disminución en los síntomas de TEPT y depresión con el tiempo. Sin embargo, los participantes en el grupo de exposición limitada tuvieron una disminución mayor en síntomas de TEPT y depresión al inicio de la atención, pero no demostraron una mejoría mayor de los síntomas a largo plazo a los 12 meses en comparación con los otros grupos. Estos resultados sirven de base para los modelos de desarrollo de TEPT y tienen implicaciones para la detección y manejo clínico de los miembros en servicio expuestos a combate.

A prediction model of military combat and training exposures on VA service-connected disability: a CENC study.

Background: Research has shown that number of and blast-related Traumatic Brain Injuries (TBI) are associated with higher levels of service-connected disability (SCD) among US veterans. This study builds and tests a prediction model of SCD based on combat and training exposures experienced during active military service.Methods: Based on 492 US service member and veteran data collected at four Department of Veterans Affairs (VA) sites, traditional and Machine Learning algorithms were used to identify a best set of predictors and model type for predicting %SCD ≥50, the cut-point that allows for veteran access to 0% co-pay for VA health-care services.Results: The final model of predicting %SCD ≥50 in veterans revealed that the best blast/injury exposure-related predictors while deployed or non-deployed were: 1) number of controlled detonations experienced, 2) total number of blast exposures (including controlled and uncontrolled), and 3) the total number of uncontrolled blast and impact exposures.Conclusions and Relevance: We found that the highest blast/injury exposure predictor of %SCD ≥50 was number of controlled detonations, followed by total blasts, controlled or uncontrolled, and occurring in deployment or non-deployment settings. Further research confirming repetitive controlled blast exposure as a mechanism of chronic brain insult should be considered.

British military women: combat exposure, deployment and mental health.

BACKGROUND: Internationally, women are about to undertake combat duties alongside their male colleagues. The psychological effect of this policy change is largely unknown. AIMS: To explore the mental health impact of combat exposure among military women. METHODS: Self-report, between-subjects survey data were collected in Iraq and Afghanistan on four occasions between 2009 and 2014 (n = 4139). Differences in mental health, stigmatization, deployment experiences, intimate relationship impact, perception of family support levels, unit cohesion, leadership and help-seeking were compared between deployed men and women. Comparisons were repeated with the study sample stratified by level of combat exposure. Outcomes were examined using logistic regression adjusted for socio-demographic, mental health and military factors. RESULTS: Overall, 4.1% of women and 4.3% of men reported post-traumatic stress disorder (PTSD) (odds ratio (OR) 1.31, 95% confidence interval (95% CI) 0.70-2.46); 22% of women and 16% of men reported symptoms of common mental disorder (CMD) (OR 1.52, 95% CI 1.11-2.08). Women were less likely to report mental health-related stigmatization (OR 0.68, 95% CI 0.53-0.87), negative relationship impact from deployment (OR 0.69, 95% CI 0.49-0.98) and subjective unit cohesion (OR 0.69, 95% CI 0.53-0.90). Help-seeking for emotional problems was similar by gender (OR 1.22, 95% CI 0.84-1.77). Overall, outcomes were minimally impacted by level of combat exposure. CONCLUSIONS: Although women experienced more CMD symptoms, PTSD symptoms were similar by gender. Subject to confirmation of the study findings, women may not require enhanced mental healthcare during deployment for exposure-based conditions such as PTSD when undertaking the ground close combat role.
