Predictors of Symptom Increase in Subsyndromal PTSD Among Previously Deployed Military Personnel.

Introduction: Subsyndromal PTSD (sub-PTSD) is associated with functional impairment and increased risk for full PTSD. This study examined factors associated with progression from sub-PTSD to full PTSD symptomatology among previously deployed military veterans.

Materials And Methods: Data were drawn from a longitudinal survey of Navy and Marine Corps personnel leaving military service between 2007 and 2010 administered immediately before separation (baseline) and ~1 year later (follow-up).

Blast Exposure and Risk of Recurrent Occupational Overpressure Exposure Predict Deployment TBIs.

Introduction: Traumatic brain injury (TBI) has been the leading cause of morbidity and mortality in recent military conflicts and deployment-related TBIs are most commonly caused by blast. However, knowledge of risk factors that increase susceptibility to TBI following an acute, high-level blast is limited. We hypothesized that recurrent occupational overpressure exposure (ROPE) may be one factor that increases susceptibility to mild TBI (mTBI) following blast.

Prevalence of Posttraumatic Stress Disorder and Psychological Comorbidities Among U.S. Active Duty Service Members, 2006-2013.

Among active duty service members, posttraumatic stress disorder (PTSD) diagnoses have increased dramatically since 2000. Because psychiatric comorbidity is more common for PTSD than for other mental health disorders, we examined the prevalence estimates of disorders comorbid or trimorbid with PTSD in this study. The medical records of 523,626 female and male active duty Sailors and Marines who entered the U.

Posttraumatic stress disorder after combat zone deployment among Navy and Marine Corps men and women.

Background: As more women are deployed into combat environments, preliminary findings have been inconsistent regarding gender differences in symptoms of posttraumatic stress disorder (PTSD) following deployment. Very little is known about the experiences of Navy and Marine Corps personnel deployed to combat zones.

Methods: The study population consisted of Navy and Marine Corps personnel who completed a Post-Deployment Health Assessment upon return from deployment to Iraq, Afghanistan, or Kuwait during 2008 and 2009 and a Post-Deployment Health Reassessment approximately 6 months later.

Etiology of depression comorbidity in combat-related PTSD: a review of the literature.

Posttraumatic stress disorder is often diagnosed with other mental health problems, particularly depression. Although PTSD comorbidity has been associated with more severe and chronic symptomology, relationships among commonly co-occurring disorders are not well understood. The purpose of this study was to review the literature regarding the development of depression comorbid with combat-related PTSD among military personnel.

Sex differences in cardiovascular and subjective stress reactions: prospective evidence in a realistic military setting.

Evidence points to heightened physiological arousal in response to acute stress exposure as both a prospective indicator and a core characteristic of posttraumatic stress disorder (PTSD). Because females may be at higher risk for PTSD development, it is important to evaluate sex differences in acute stress reactions. This study characterized sex differences in cardiovascular and subjective stress reactions among military survival trainees.

Implications of psychiatric comorbidity among combat veterans.

Limited research exists regarding the rates of and outcomes associated with psychiatric comorbidity among active duty military personnel. This study investigated the rates of comorbid psychiatric diagnoses among 81,720 U.S.

A prospective study of factors affecting recovery from musculoskeletal injuries.

Purpose: Research suggests the importance of psychosocial factors in recovery from musculoskeletal injuries. The objective of this study was to identify predictors of recovery among U.S.

Predictors of psychiatric disorders in combat veterans.

Background: Most previous research that has examined mental health among Operation Enduring Freedom and Operation Iraqi Freedom (OEF/OIF) combatants has relied on self-report measures to assess mental health outcomes; few studies have examined predictors of actual mental health diagnoses. The objective of this longitudinal investigation was to identify predictors of psychiatric disorders among Marines who deployed to combat in Iraq and Afghanistan.

Methods: The study sample consisted of 1113 Marines who had deployed to Iraq or Afghanistan.

Substance abuse counselor and client reports of mental health screening and enhanced practices.

Objective: The objective of this study was to examine mental health screening practices and attitudes from both counselor and client perspectives in the U.S. Marine Corps substance abuse program.

Anxiety and depression in Marines sent to war in Iraq and Afghanistan.

Although the effects of combat deployment on posttraumatic stress disorder have been extensively studied, little is known about the effects of combat deployment on depression and anxiety. This study examined the factors associated with anxiety and depression in a sample of 1560 US Marines who were deployed to Iraq and Afghanistan. Eleven demographic and psychosocial factors were studied in relation to depression and anxiety.

Mental health and turnover following an initial term of military service.

Objective: This study compared the rates of mental disorders between Marines who re-enlisted and Marines who separated after 1 term, distinguishing between Marines who were and were not recommended for re-enlistment.

Methods: Participants included 28,693 male Marines enlisting for 4-year terms between 2002 and 2003, including 9,338 who re-enlisted after 1 term, 18,177 who voluntarily separated after 1 term, and 1,184 who were not recommended for re-enlistment and separated after 1 term.

Results: Analysis revealed disproportionately high rates of mental disorders among Marines not recommended for re-enlistment (Odds Ratio = 8.

Postcombat outcomes among Marines with preexisting mental diagnoses.

Preexisting mental disorders are not always considered in mental health studies with military populations, even though prior diagnoses may be a risk factor for additional psychiatric harm stemming from combat exposure, as well as postdeployment behavioral problems. The objectives of this study were to investigate postcombat psychiatric and career outcomes among Marines with preexisting mental disorder diagnoses who deployed to combat in Iraq, Afghanistan, or Kuwait from 2002 to 2008. Marines with a preexisting diagnosis were 3.

Psychiatric diagnoses and punishment for misconduct: the effects of PTSD in combat-deployed Marines.

Background: Research on Vietnam veterans suggests an association between psychological problems, including posttraumatic stress disorder (PTSD), and misconduct; however, this has rarely been studied in veterans of Operation Iraqi Freedom or Operation Enduring Freedom. The objective of this study was to investigate whether psychological problems were associated with three types of misconduct outcomes (demotions, drug-related discharges, and punitive discharges.)

Methods: A population-based study was conducted on all U.

Factors associated with antisocial behavior in combat veterans.

The objective of this study was to identify factors associated with antisocial behavior in 1,543 Marines who deployed to combat zones in support of conflicts in Iraq and Afghanistan during 2002-2007. Five factors were associated with antisocial behavior in multivariate analyses: post-traumatic stress disorder (PTSD) symptoms, deployment-related stressors, combat exposure, younger age, and being divorced. PTSD symptoms had a stronger association with antisocial behavior than any other variable.

Psychosocial predictors of military misconduct.

The objective of this longitudinal study was to determine psychosocial predictors of military misconduct in a cohort of Marine Corps war veterans. The study included data from 20,746 male Marines who completed a life history questionnaire during initial basic training and were subsequently deployed to a combat zone. Associations between psychosocial variables, psychiatric diagnoses, and subsequent misconduct outcomes were analyzed using Cox proportional hazards regression.

Correlates of posttraumatic stress disorder symptoms in Marines back from war.

The effect of combat and operational stress on the mental health of military personnel is a major concern. The objective of this study was to identify factors associated with possible posttraumatic stress disorder (PTSD). A questionnaire was completed by 1,569 Marines who deployed in support of conflicts in Iraq and Afghanistan (2002-2007).

Prospective analysis of psychiatric risk factors in marines sent to war.

The objective of this longitudinal study was to identify risk factors for combat-related psychiatric disorders. The sample consisted of 6442 enlisted U.S.

Incidence of insulin-requiring diabetes in the US military.

Aims/hypothesis: The aim of the study was to determine age- and race-related, and overall incidence rates of insulin-requiring diabetes in adults in the US military.

Methods: Electronic records for admissions to US military and Tricare hospitals during 1990-2005 and visits to military clinics during 2000-2005 were identified using the Career History Archival Medical and Personnel System at the Naval Health Research Center, San Diego, CA, USA. Population data were obtained from the Defense Manpower Data Center and Defense Medical Epidemiology Database.

Psychosocial predictors of return to duty among marine recruits with musculoskeletal injuries.

Psychosocial factors may have an important impact on injury recovery and return to work. To explore the influence of psychosocial factors in a cohort of injured military personnel, data were collected from 166 Marine Corps basic training recruits with musculoskeletal injuries. This sample was followed prospectively to determine whether they graduated from basic training or were discharged from the Marines.

Psychiatric diagnoses in historic and contemporary military cohorts: combat deployment and the healthy warrior effect.

Research studies have identified heightened psychiatric problems among veterans of Operation Iraqi Freedom (OIF) and Operation Enduring Freedom (OEF). However, these studies have not compared incidence rates of psychiatric disorders across robust cohorts, nor have they documented psychiatric problems prior to combat exposure. The authors' objectives in this study were to determine incidence rates of diagnosed mental disorders in a cohort of Marines deployed to combat during OIF or OEF in 2001-2005 and to compare these with mental disorder rates in two historical and two contemporary military control groups.
