The physical and mental health of Australian Vietnam veterans 3 decades after the war and its relation to military service, combat, and post-traumatic stress disorder

The role of military service in preventing depression in China: evidence from a nationally representative longitudinal survey

BACKGROUND

Despite recognition in the West that military veterans experience more mental health issues than the general population, little research has focused on this subject in China. This study examined the associations between male veterans' military experience and depression in China.

METHODS

A sample of 12,914 men including 669 veterans was included in the final analysis and propensity score matching, multivariable regressions and fixed effect model were used.

RESULTS

The military experience was associated with a lower likelihood of depression in male veterans. In the subgroup analysis, military experience was associated with a lower likelihood of depression among married and urban male veterans. Military experience was also associated with a lower likelihood of depression in both "junior college and above" and "below junior college" groups. In contrast, evidence was lacking regarding the associations between military experience and depression for unmarried and rural veterans.

CONCLUSIONS

Individual characteristics could influence the relationship between military experience and depression in male veterans, and the mental health of veterans should be paid more attention and guaranteed.

General Practitioners' Own Traumatic Experiences and Their Skills in Addressing Patients' Past History of Adversities: A Cross-Sectional Study in Portugal

Addressing trauma has been found to be important for primary care patients, as it can improve their health-related outcomes. We aimed to assess how Portuguese general practitioners' (GPs) past history of traumatic events (TEs) and adverse childhood experiences (ACEs) influence their clinical communication skills when addressing their patients' past history of adversities. An online survey was circulated by email to GPs' associations and through GPs' social media groups. A sample of 143 GPs participated in this study. GPs' exposure to ACEs and TEs was assessed using the Childhood Trauma Questionnaire-Short Form and the Life Events Checklist for the DSM-5. To evaluate clinical communication skills, we adapted the Self-confidence Scale and used the Jefferson Scale of Physician Empathy. GPs identified barriers to addressing trauma routinely, including a lack of time (86.7%) and a fear of causing further patient suffering (56.6%). GPs' exposure to TEs and ACEs was positively correlated with scores in some dimensions of self-confidence and empathy (r values varying from 0.170 to 0.247). GPs exposed to traumatic experiences felt more confident when addressing their patients' adversities and were more empathic when conducting therapeutic relationships. This study shows that GPs with a history of traumatic experiences are able to address their patients' adversities; however, they lack proper training and better patient care conditions, such as more time and more resources available for patient guidance.

Grit but Not Help-Seeking Was Associated with Food Insecurity among Low Income, At-Risk Rural Veterans

Rural veterans have poorer health, use healthcare services less often than their urban counterparts, and have more prevalent food insecurity than average U.S. households. Food insecurity and resource use may be influenced by modifiable psychological attributes such as grit and help-seeking behaviors, which may be improved through interventions. Grit and help-seeking have not been previously evaluated among rural veterans. Thus, this cross-sectional study evaluated the hypothesis that grit and help-seeking were associated with food insecurity and the use of resources. Food security, resource use, grit, and help-seeking behavior were assessed among rural veterans (≥18 years) from five food pantries in southern Illinois counties (n = 177) from March 2021 to November 2021. Adjusted multiple regression was used to estimate the relationship between the odds of food insecurity and the use of resources with grit and help-seeking scores. Higher grit scores were significantly associated with lower odds of food insecurity (OR = 0.5, p = 0.009). No other associations were detected. The results provided evidence to inform the content of future educational interventions to improve food insecurity and address health disparities among rural veterans by addressing grit. The enhancement of psychological traits such as grit is related to food security and has the potential to benefit other aspects of well-being.

Use of home care services by older Veterans and dependants in Melbourne, Australia, 2007-2016

LAY SUMMARY

Military service has an impact on health and well-being across the life course. However, there is little research on older Veterans and dependants who use home care to enable them to remain living in the community. The authors analysed data from a Melbourne, Australia, home care organization’s electronic care records to explore the differences between clients supported by the Department of Veterans’ Affairs and clients in the general home nursing population. Results showed the greater needs of and complexity of care utilized by Veterans and dependants. Funding structures and support services need to account for these needs in older age.

The mental health of Vietnam theater veterans-the lasting effects of the war: 2016-2017 Vietnam Era Health Retrospective Observational Study

Mental health data from the 2016-2017 Vietnam Era Health Retrospective Observational Study (VE-HEROeS) were analyzed by cohort, represented by United States Vietnam theater veterans (VTs) who served in Vietnam, Cambodia, and Laos; nontheater veterans (NTs) without theater service; and age- and sex-matched nonveterans (NVs) without military service. The exposure of interest was Vietnam theater service. Surveys mailed to random samples of veterans (n = 42,393) and nonveterans (n = 6,885) resulted in response rates of 45.0% for veterans (n = 6,735 VTs, M_age = 70.09, SE = 0.04; n = 12,131 NTs) and 67.0% for NVs (n = 4,530). We examined self-report data on four mental health outcomes: probable posttraumatic stress disorder (PTSD), depression, psychological distress, and overall mental health functioning. Weighted adjusted odds ratios (aORs) between each outcome and cohort were estimated, controlling for covariates in four models: cohort plus sociodemographic variables (Model 1), Model 1 plus physical health variables (Model 2), Model 2 plus potentially traumatic events (PTEs; Model 3), and Model 3 plus other military service variables (Model 4). Mental health outcome prevalence was highest for VTs versus other cohorts, with the largest aOR, 2.88, for PTSD, 95% CI [2.46, 3.37], p < .001 (Model 4, VT:NT). Physical health and PTEs contributed most to observed effects; other service variables contributed least to aORs overall. Mental health dysfunction persists among VTs years after the war's end. The present results reaffirm previous findings and highlight the need for continued mental health surveillance in VTs.

Intergenerational Transmission of Posttraumatic Stress Disorder in Australian Vietnam Veterans' Daughters and Sons: The Effect of Family Emotional Climate While Growing Up

Posttraumatic stress disorder (PTSD) in military veterans increases the risk of PTSD in their offspring, a concept known as "intergenerational transmission;" however, the mechanism by which this transmission may occur is, as yet, undetermined. The present study included a nonclinical sample of 197 Australian Army veterans of the Vietnam War who were interviewed 17 years before in-person interviews of their adult daughters (n = 163) and sons (n = 120) were conducted. Veterans' PTSD symptoms were assessed using the Mississippi Scale for Combat-Related PTSD. Approximately 17 years later, offspring PTSD symptoms were assessed using the Clinician-Administered PTSD Scale for DSM-IV. In addition, offspring described the family emotional climate during their youth; responses were coded using the Family Affective Attitude Rating Scale (FAARS) to produce scale scores of veterans' negative, positive, and family relationship styles. A path analysis was conducted via structural equation modeling to test for significant path coefficients between veteran PTSD, family emotional climate, and offspring PTSD symptoms. For daughters, significant path coefficients were observed between veteran PTSD scores and FAARS scores, path coefficient = -.268; FAARS scores and offspring CAPS severity scores, path coefficient = -.223; and veteran PTSD scores and daughters' CAPS severity scores, path coefficient = .186. No satisfactory model could be found for sons. The results suggest that a positive emotional climate while growing up may be a significant protective factor against the development of PTSD in veterans' daughters, but other factors remain significant in veteran-to-offspring intergenerational transmission.

A Modeling and Machine Learning Pipeline to Rationally Design Treatments to Restore Neuroendocrine Disorders in Heterogeneous Individuals

Heterogeneity among individual patients presents a fundamental challenge to effective treatment, since a treatment protocol working for a portion of the population often fails in others. We hypothesize that a computational pipeline integrating mathematical modeling and machine learning could be used to address this fundamental challenge and facilitate the optimization of individualized treatment protocols. We tested our hypothesis with the neuroendocrine systems controlled by the hypothalamic–pituitary–adrenal (HPA) axis. With a synergistic combination of mathematical modeling and machine learning (ML), this integrated computational pipeline could indeed efficiently reveal optimal treatment targets that significantly contribute to the effective treatment of heterogeneous individuals. What is more, the integrated pipeline also suggested quantitative information on how these key targets should be perturbed. Based on such ML revealed hints, mathematical modeling could be used to rationally design novel protocols and test their performances. We believe that this integrated computational pipeline, properly applied in combination with other computational, experimental and clinical research tools, can be used to design novel and improved treatment against a broad range of complex diseases.

Trastornos del sueño en emergencias y desastres

Los trastornos del sueño son frecuentes en la población y una causa importante de morbilidad. El objetivo de esta revisión es evaluar las alteraciones del sueño en periodos de emergencia y desastres. A lo largo de la historia, la esfera biopsicosocial y el sueño de las personas ha sido abrumada por múltiples eventos a gran escala, tales como desastres naturales, tragedias provocadas por el hombre, conflictos bélicos, crisis sociales y pandemias, cuya experiencia puede derivar en problemas de salud a corto, mediano y/o largo plazo. En los estudios analizados, se ha observado el impacto negativo de las emergencias y desastres en el sueño, por lo que ha cobrado gran relevancia la difusión y promoción de medidas que incentiven el buen dormir. Debido a la llegada del COVID-19 y a la situación de confinamiento por periodos prolongados en el hogar para prevenir su propagación, han surgido importantes consecuencias a nivel social. Ciertos factores ocupacionales y características de los desastres se asocian a mayor comorbilidad, un alto riesgo de experimentar agotamiento físico, trastornos psicológicos e insomnio en grupos altamente vulnerables, como lo son los profesionales de la salud, rescatistas y socorristas. El insomnio es el trastorno de sueño más frecuente en la población general y su empeoramiento en el contexto de pandemia por COVID-19 representa un nuevo problema en salud pública. Es por ello, que es indispensable promover campañas de prevención de salud física y mental orientados a la pesquisa precoz y manejo de patologías de la esfera psicosocial, dentro de las posibilidades socioeconómicas.

Co-occurrence Pattern of Posttraumatic Stress Disorder and Depression in People Living With HIV: A Latent Profile Analysis

Background: The comorbidity of posttraumatic stress disorder (PTSD) and depression is common among people living with the HIV (PLWH). Given the high prevalence and serious clinical consequences of the comorbidity of these two disorders, we conducted a latent profile analysis to examine the co-occurrence pattern of PTSD and depression in PLWH.

Methods: The data for this cross-sectional study of PLWH were collected from 602 patients with HIV in China. A secondary analysis using latent profile analysis was conducted to examine HIV-related PTSD and depression symptoms.

Results: A four-class solution fits the data best, with the four classes characterized as asymptomatic (42.9%), mild symptoms (33.9%), low to moderate symptoms (19.8%), and high to moderate symptoms (3.4%). The severity of PTSD and depression symptoms was comparable in this solution, and no group was dominated by PTSD or depression.

Conclusion: The absence of a distinct subcluster of PLWH with only PTSD or depression symptoms supports that PTSD and depression in PLWH are psychopathological manifestations after traumatic exposures. Health care staff should pay more attention to the existence of comorbid symptoms of individuals, develop integrated interventions for the symptoms cluster, and evaluate their effectiveness in clinical practice.

Australian military and veterans' mental health care: improving assessment of military personnel and veterans

OBJECTIVE

To describe key practical knowledge and skill components required for clinicians involved with the assessment of military personnel and veterans.

CONCLUSIONS

Assessment of military and veterans' mental health issues involves a tailored history-taking process that includes specific aspects of service, transition and reporting requirements. Recommendations for the detailed assessment of military personnel and veterans are provided. Comorbid conditions, chronic pain and the needs of both women and older veterans are also discussed.

Variation in health service use by veterans with an accepted disability of post-traumatic stress disorder who had a service record post 1975: a cluster analysis

Background

The use of health services is likely to vary among veterans with an accepted disability of post-traumatic stress disorder (PTSD), however, the extent of variation is not known. We aimed to determine the extent and type of health services used by veterans with an accepted disability of PTSD.

Methods

The cohort included veterans who served post 1975, were eligible for all Australian Government Department of Veterans’ Affairs funded health services, had PTSD as an accepted disability prior to July 2015 and were alive at the 30 June 2016. Veterans were assigned to groups based on their use of health services using K-means cluster analysis.

Results

The cohort comprised five clusters involving 2286 veterans. The largest cluster (43%) were a younger, general practitioner (GP) managed cluster who saw their GP quarterly and the psychiatrist twice a year. The second GP cluster (30%) had higher levels of physical comorbidity. The psychiatrist managed cluster (14%) had a mean of 12 psychiatrist visits and one PTSD hospitalisation in the year. The remaining two clusters involved GP and allied healthcare, but no psychologist care. High levels of antidepressant use occurred in all clusters, ranging from 44% up to 69%. The psychiatrist managed cluster had 47% on antipsychotics and 58% on anxiolytics.

Conclusion

Our study highlights the heterogeneity in health service use. These results identify the significant health utilisation required for up to one-sixth of veterans with PTSD and the significant role of primary care physicians in supporting veterans with PTSD.

Consistencies and differences in posttraumatic stress disorder and depression trajectories from the Wenchuan earthquake among children over a 4-year period

BACKGROUND

Posttraumatic stress disorder (PTSD) and depression are the most prevalent mental disorders following disasters, and they often co-occur. The current study investigated trajectories of PTSD and depression among children after exposure to the Wenchuan earthquake and identified factors associated with PTSD or depression trajectories.

METHODS

Three hundred children who were exposed to the Wenchuan earthquake reported PTSD and depression symptoms 4, 16, 29, 40 and 52 months after the disaster, and potential predictors (age, earthquake exposure, prequake trauma and parental relationship) were identified. The PTSD and depression trajectories were identified with latent growth mixture modeling (LGMM), and the predictors were explored with multinomial logistic regression.

RESULTS

Two depression trajectories emerged: resilient (66.2%) and chronic (33.8%). Three PTSD trajectories emerged: resilient (74.9%), recovery (7.5%) and relapsing (17.7%). Overall, 57.3% of the children had low depression and PTSD symptoms over four years. Depression trajectories were significantly predicted by age and parental relationship, while PTSD trajectories were significantly predicted by trauma exposure and prequake trauma experience.

LIMITATIONS

The children's prequake mental health statuses were unknown, and all assessments relied on self-report questionnaires.

CONCLUSION

The postdisaster developmental course of depression was more stable than that of PTSD, and PTSD and depression had different risk factors. Previous studies that focus only on PTSD or depression trajectories may overestimate children's resilient responses. Longer-term postdisaster intervention should pay more attention to depression than to PTSD.

The Mediation Effect of Hyperarousal Symptoms on the Relationship Between Childhood Physical Abuse and Suicidal Ideation of Patients With PTSD

Objective: This study examined the relationship of childhood physical abuse, posttraumatic stress disorder (PTSD), depression, and suicide in patients with PTSD through path analysis. Materials and Methods: A total of 114 patients with PTSD (36 men and 78 women) were recruited and completed psychological assessments including the Childhood Trauma Questionnaire, the scale for suicidal ideation, the clinician-administered PTSD scale for the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition, the PTSD checklist, and the Hospital Anxiety and Depression Scale. Structural equation modeling was used to evaluate the results. We developed a model including childhood physical abuse experience as the causal variable, suicidal ideation as a result variable, and PTSD and depression as mediation variables. PTSD symptoms were divided into four clusters [intrusion, avoidance, negative cognition and mood, and altered arousal and reactivity (hyperarousal)] to determine predictive power for suicide. Results: PTSD symptoms fully mediated the relationship between childhood physical abuse and suicidal ideation. Furthermore, PTSD symptoms fully mediated the relationship between childhood physical abuse and depression. Among the PTSD symptoms, hyperarousal was the only symptom cluster that mediated the relationship between childhood physical abuse and suicidal ideation. The symptom clusters of negative cognition and mood as well as hyperarousal mediated the relationship between childhood physical abuse and depression. Conclusions: This study presents a link between childhood physical abuse and current symptoms in patients with PTSD, and highlights specific PTSD symptom clusters (i.e., hyperarousal, negative cognition and mood) that may increase the risk for psychopathology later in life.

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.

Trauma-Informed Care in Primary Health Settings-Which Is Even More Needed in Times of COVID-19

Included in the general practitioner’s (GP) core competencies is the ability to adopt a person-centered approach, and the use of the biopsychosocial model in their clinical work. Traumatic events (TEs) are frequently experienced within the population and are known to dysregulate the stress response system and to be associated with psychiatric and physical disorders. GPs may feel reluctant to confront TEs for a variety of reasons, such as a lack of sufficient training in trauma-informed care or a fear of causing harm when discussing a patient’s more complicated issues, among others. This perspective paper aims to review the existing studies that support the practice of trauma-informed healthcare and to summarise best practices. Studies have shown that patients appreciate the questions that clinicians ask them about trauma-related issues and that they understand that this can be important for their healthcare. Furthermore, asking about trauma-related issues in a patient-centered and empathic way can result in better doctor–patient relationships, which improves the levels of satisfaction of both the patient and the doctor with the consultation, as well as improved health-related outcomes. As past traumatic experiences increase the risk of developing post-traumatic stress disorder on exposure to a new TE, the onset of the COVID-19 pandemic has led to trauma-informed care becoming even more important if the strategy is to continue to invest in preventive medicine.

Comparing negative health indicators in male and female veterans with the Canadian general population

Introduction

Sex-based information on differences between Canadian veterans and the general population is important to understand veterans’ unique health needs and identify areas requiring further research. This study compared various health indicators in male and female veterans with their Canadian counterparts.

Methods

Health indicators for recent-era Regular Force veterans (released between 1998 and 2015) were obtained from the 2016 Life After Service Survey and compared with the general population in the 2015–16 Canadian Community Health Survey using a cross-sectional approach. Age-adjusted rates and 95% CIs were calculated for males and females separately.

Results

Compared with Canadians, veterans (both sexes) reported higher prevalence of fair or poor health and mental health, needing help with one or more activity of daily living, lifetime suicidal ideation and being diagnosed with mood and anxiety disorders, post-traumatic stress disorder, migraines, back problems, chronic pain, arthritis, ever having cancer, hearing problems, chronic pain and gastrointestinal problems. A higher prevalence of cardiovascular disease (all types) and high blood pressure was observed in male veterans compared with their Canadian counterparts. Within veterans only, males reported a higher prevalence of diagnosed hearing problems and cardiovascular disease compared with females; conversely females reported a higher prevalence of diagnosed migraines, mood, anxiety and gastrointestinal disorders, and needing help with activities of daily living. These sex differences are similar to the Canadian general population. Some similarities in reporting prevalence between male and female veterans (eg, fair or poor mental health, lifetime suicidal ideation, arthritis, asthma, lifetime cancer incidence, chronic pain and diabetes) were not observed in other Canadians.

Conclusion

Male and female veterans differed from comparable Canadians, and from each other, in various areas of health. Further research is needed to explore these findings, and veteran-based policies and services should consider sex differences.

Long-Term Psychological Consequences of World War II Trauma Among Polish Survivors: A Mixed-Methods Study on the Role of Social Acknowledgment

Background

The research on the psychological consequences of World War II (WWII) trauma has predominantly focused on concentration camp and Holocaust survivors. Only a few studies have been undertaken among civilian survivors of WWII.

Objectives

The purpose of this study was to examine the association between perceived social acknowledgment of WWII trauma and the level of post-traumatic stress disorder (PTSD) and depressive symptoms among Polish survivors of WWII by employing a mixed-methods design (i.e., a quantitative analysis supported by qualitative interviews).

Method

In the quantitative part, 123 participants filled out: the list of WWII-related traumatic events, the PTSD Checklist for the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (PCL-5), the shortened version of the Geriatric Depression Scale (GDS), and the Social Acknowledgment Questionnaire (SAQ). In the qualitative part, an interpretative phenomenological analysis (IPA) of participants’ reminiscences of WWII was examined.

Results

Although we observed a direct positive association between the number of WWII-related traumatic events and the intensity of PTSD and depressive symptoms, these relationships changed when we entered the social acknowledgment construct into the model. Specifically, we found that perceived social acknowledgment (general disapproval) was a mediator of the relationship between the number of WWII traumatic events and the intensity of PTSD symptoms only, and not of depressive symptoms. In the qualitative part, three themes relating to traumatic reminiscences emerged among the participants: parental efficacy, parental betrayal, and support from the invader.

Conclusion

Our study showed the significance of the general social acknowledgment in the long-term mental consequences of the WWII trauma in Poland. In addition, the results of our study may be an adjunct to the discussion on the long-term impact of WWII trauma in Poland and the factors that hindered its social recognition.

Development and Trial Implementation of a 30-Day Outpatient Program for Subthreshold PTSD

INTRODUCTION

Posttraumatic stress disorder (PTSD) negatively impacts service members at high rates, causing considerable physical and psychological consequences. Additionally, many service members experience subthreshold PTSD (i.e., experiencing PTSD symptoms that do not meet full diagnostic criteria), which has also been shown to cause significant functional impairment and can be a precursor to the development of full PTSD. Typically, treatment for PTSD at Walter Reed National Military Center facility includes weekly outpatient individual therapy over a three-month period or referral to an intensive outpatient program (IOP), which emphasizes group treatment. Inclusion in these programs is dependent on the severity of symptoms. Service members with subthreshold symptoms do not typically qualify for an IOP, and weekly outpatient therapy does not meet the needs of some service members or their commands.

METHODS

As a result, we developed an alternative program with the intention of allowing service members with subthreshold PTSD to receive treatment and return to full-duty status more rapidly. The program emphasized bi-weekly evidenced-based PTSD therapies treatment adjusted to meet the needs of each service member along with the option of adjunct individual and group treatments.

RESULTS

While this program is ongoing and we have not yet conducted outcome data analyses, the structure and pace of this program have the potential to produce quicker functional improvements, prevent the development of full PTSD symptoms, and reduce long-term or recurring healthcare utilization.

CONCLUSION

Although more research is needed, there exists preliminary empirical evidence of efficacy for an accelerated protocol of biweekly evidence-based therapy for service members with subthreshold PTSD.

Combat, Posttraumatic Stress Disorder, and Smoking Trajectory in a Cohort of Male Australian Army Vietnam Veterans

Background

Whether trauma exposure itself or consequent posttraumatic stress disorder (PTSD) is primarily responsible for smoking and failure to quit remains unclear.

Methods

A cohort of male Australian Vietnam veterans (N = 388) was interviewed twice, 22 and 36 years after their return to Australia using standardized psychiatric diagnostic and health interviews and assessment of combat exposure. The smoking trajectory over time revealed a spectrum of outcomes (never smoked, early quitters, late quitters, and continuing smokers). Analysis used multivariate statistics to assess the relative contributions of combat trauma exposure and PTSD while controlling for potential confounders.

Results

The trajectory of smoking over time revealed that 21.9% of veterans had never smoked, 45.1% had quit smoking by the time of wave 1, 16.2% were current smokers at wave 1 who had quit by the time of wave 2, 2.8% were late adopters who were current smokers, and 13.9% were continuing smokers. Smoking was associated in single-predictor models with demographics, intelligence, combat exposure, PTSD symptom clusters and diagnosis, and alcohol disorders. Multivariate analysis revealed that PTSD, combat, and intelligence were related to the smoking spectrum but, after adding demographics and other Axis I psychiatric diagnoses, only combat remained significant. No PTSD symptom cluster uniquely predicted smoking status.

Conclusions

The results suggest that trauma exposure in the form of military combat may be a more robust predictor of smoking status over time than PTSD. It may be stress itself, rather than poststress disorder, that is more germane to smoking and failure to quit.

Implications

Exposure to traumatic stress and development of PTSD have been implicated separately in the maintenance of smoking. This longitudinal cohort study of smoking in war veterans up to three decades postwar enabled evaluation of traumatic stress exposure in combat and the course of PTSD in smoking and quitting while controlling for intelligence, background disadvantage, and other psychiatric conditions. Combat rather than PTSD emerged as more significant to smoking status, suggesting that it may be the traumatic stress itself rather than the development of a poststress disorder that is more germane to smoking in war veterans.

Spirometric Pulmonary Restriction in Herbicide-Exposed U.S. Vietnam War Veterans

Spirometric restriction in herbicide-exposed U.S. Army Chemical Corps Vietnam War veterans was examined because no published research on this topic in Vietnam War veterans exists. Spirometry was conducted on 468 veterans who served in chemical operations in a 2013 study assessing the association between chronic obstructive pulmonary disease (COPD) and herbicide exposure. Exposure was verified based on blood serum values of 2,3,7,8-tetrachlorodibenzo-p-dioxin. Further, the association between herbicide exposure and spirometry restriction (forced expiratory volume in one second (FEV₁)/forced vital capacity (FVC) ≥ lower limit of normal (LLN) and FVC < LLN) was tested after adjustment for military characteristics, selected anthropometrics, and other predictors using multivariable regression. Spirometric restriction in herbicide sprayers (15.7%, 95% CI: 10.6, 20.9) was almost twice that of nonsprayers (9.91%, 95% CI: 5.9, 13.9) (p = 0.081). While spirometric restriction was not significantly associated with herbicide exposure (adjusted odds ratio (aOR) = 1.64, 95% CI: 0.82, 3.29) despite the greater prevalence of restriction in sprayers versus nonsprayers, spirometric restriction was significantly associated with race/ethnicity (aOR = 3.04, 95% CI: 1.36, 6.79) and waist circumference (aOR = 2.46, 95% CI: 1.25, 4.85). Because restrictive pulmonary disease may result from chemically-induced inflammation or sensitivity, research on chemical exposures and restriction in veterans should continue. Future study should include full pulmonary function testing, targeted research designs, and a wider set of explanatory variables in analysis, such as other determinants of health.

The Value of Physical Symptoms in Screening For Posttraumatic Stress Disorder in the Military

Physical symptoms are highly comorbid with posttraumatic stress disorder (PTSD). As PTSD is underdiagnosed, this study explored the value of self-reported physical symptoms in screening for 30-day PTSD in military personnel. Two physical symptom scales were constructed using items from a 67-item health symptom checklist, clinical interviews were used as the diagnostic reference standard, and diagnostic utility of physical symptoms was compared with the current gold standard screen, the PTSD checklist (PCL). Receiver operating characteristic analyses showed that both a 9-item and a 10-item physical symptom scale were of value in predicting PTSD (areas under the curve 0.81 and 0.85). Importantly, two thirds of PTSD positive personnel missed by the PCL were captured with physical symptoms scales, and when physical symptoms were added to the PCL, prediction was improved (areas under the curve 0.90 to 0.92). Our findings highlight the value of including assessing physical symptoms in PTSD screening.

Posttraumatic Stress Disorder in Older Adults: A Conceptual Review

Objectives: We provide a review of the literature on posttraumatic stress disorder (PTSD) in older adults, focusing largely on older U.S. military veterans in two primary areas: 1) assessment and diagnosis and 2) non-pharmacological treatment of PTSD in late life. Methods: We performed a search using PubMed and Academic Search Premier (EBSCO) databases and reviewed reference sections of selected papers. We also drew on our own clinical perspectives and reflections of seven expert mental health practitioners. Results: Rates of PTSD are lower in older compared with younger adults. The presence of sub-syndromal/partial PTSD is important and may impact patient functioning. Assessment requires awareness and adaptation for potential differences in PTSD experience and expression in older adults. Psychotherapies for late-life PTSD appear safe, acceptable and efficacious with cognitively intact older adults, although there are relatively few controlled studies. Treatment adaptations are likely warranted for older adults with PTSD and co-morbidities (e.g., chronic illness, pain, sensory, or cognitive changes). Conclusions: PTSD is an important clinical consideration in older adults, although the empirical database, particularly regarding psychotherapy, is limited. Clinical Implications: Assessment for trauma history and PTSD symptoms in older adults is essential, and may lead to increased recognition and treatment.

The mental health of sons and daughters of Australian Vietnam veterans

Background

War service increases the risk of post-traumatic stress disorder (PTSD) to combatants, and has been shown to increase the risk of PTSD in their offspring. The extent to which there is an excess compared with the general population is not yet established, nor whether PTSD increases the risk of other psychiatric problems.

Methods

A national sample of 133 sons and 182 daughters of a cohort of 179 Australian Vietnam veterans' families were assessed in person, using structured psychiatric interviews. The prevalence of trauma exposures, DSM-IV (Diagnostic and Statistical Manual of Mental Disorders Fourth Edition) diagnoses and suicidality were compared with the Australian Bureau of Statistics' 2007 National Survey of Mental Health and Wellbeing data matched for age and sex. The risk of mental health problems potentially attributable to PTSD was also assessed.

Results

Sons and daughters were more likely than population expectations to report exposures to natural disasters, fire or explosions and transport accidents, and sons more likely to report exposure to toxic chemicals whereas daughters were more likely to report sexual assault. Sons and daughters had higher prevalences of alcohol and other substance dependence, depression and anxiety, and PTSD, and children's PTSD was associated with substance dependence, depression and suicidal ideation. There were strong associations between children's PTSD and comorbid conditions of substance use disorders, depression and anxiety.

Conclusions

Higher rates of mental health problems in veterans' families, together with comorbidity with PTSD and the link between veterans' and children's PTSD, suggest that the effects of trauma may continue into subsequent generations.

Treatment of military-related post-traumatic stress disorder: challenges, innovations, and the way forward

Post-traumatic stress disorder (PTSD) is one of the common mental disorders in military and veteran populations. Considerable research and clinical opinion has been focused on understanding the relationship between PTSD and military service and the implications for prevention, treatment, and management. This paper examines factors associated with the development of PTSD in this population, considers issues relating to engagement in treatment, and discusses the empirical support for best practice evidence-based treatment. The paper goes on to explore the challenges in those areas, with particular reference to treatment engagement and barriers to care, as well as treatment non-response. The final section addresses innovative solutions to these challenges through improvements in agreed terminology and definitions, strategies to increase engagement, early identification approaches, understanding predictors of treatment outcome, and innovations in treatment. Treatment innovations include enhancing existing treatments, emerging non-trauma-focused interventions, novel pharmacotherapy, personalized medicine approaches, advancing functional outcomes, family intervention and support, and attention to physical health.

Posttraumatic stress disorder: a model of the longitudinal course and the role of risk factors

Posttraumatic stress disorder (PTSD) differs from other anxiety disorders in that experience of a traumatic event is necessary for the onset of the disorder. The condition runs a longitudinal course, involving a series of transitional states, with progressive modification occurring with time. Notably, only a small percentage of people that experience trauma will develop PTSD. Risk factors, such as prior trauma, prior psychiatric history, family psychiatric history, peritraumatic dissociation, acute stress symptoms, the nature of the biological response, and autonomic hyperarousal, need to be considered when setting up models to predict the course of the condition. These risk factors influence vulnerability to the onset of PTSD and its spontaneous remission. In the majority of cases, PTSD is accompanied by another condition, such as major depression, an anxiety disorder, or substance abuse. This comorbidity can also complicate the course of the disorder and raises questions about the role of PTSD in other psychiatric conditions. This article reviews what is known about the emergence of PTSD following exposure to a traumatic event using data from clinical studies.

Posttraumatic Stress Disorder and Cancer Risk: A Nested Case-Control Study

Data regarding cancer risk for individuals who were exposed to traumatic and stressful life events are conflicting. We sought to evaluate the association between posttraumatic stress disorder (PTSD) and the risk of the four most common solid tumors: lung, breast, prostate, and colorectal cancers. We conducted four nested case-control studies using a large UK population-based database. Cases were defined as individuals with any medical code for the specific malignancy. For every case, we used incidence-density sampling to match four controls by age, sex, practice site, and both duration and calendar time of follow-up. Exposure of interest was any diagnosis of PTSD prior to cancer diagnosis. The odds ratios (ORs) and 95% confidence intervals (CIs) for cancer risk associated with PTSD were estimated using multivariable conditional logistic regression and were adjusted for smoking status, obesity, and antidepressant use. The study population included four case groups according to cancer type. There were 19,143 cases with lung cancer (74,473 matched controls), 22,163 cases with colorectal cancer (86,538 matched controls), 31,352 cases with breast cancer (123,285 matched controls), and 27,212 cases with prostate cancer (105,940 matched controls). There was no statistically significant association between PTSD and cancer risk among any of the cancer types: lung, OR = 0.73, 95% CI [0.43, 1.23]; breast, OR = 0.73, 95% CI [0.52, 1.01]; prostate, OR = 1.24, 95% CI [0.87, 1.77]; and colorectal, OR = 1.05, 95% CI [0.68, 1.62]. Our findings indicated that participants in our study with PTSD were not at increased risk of lung, breast, prostate, and colorectal cancers.

Growing up with a father with PTSD: The family emotional climate of the children of Australian Vietnam veterans

A non-clinical sample of male Australian Vietnam veterans, their wives, and adult offspring were interviewed in-person in a national epidemiological study to assess the relationship between the mental ill-health of veterans and the emotional climate of the family while the children were growing up. Veterans were assessed 17 years before their children using standardised psychiatric diagnostic interviews. Family emotional climate was assessed using offspring ratings of parental attachment, and codings of positive and negative family relationship styles based on five minute speech samples provided by the offspring. Sons and daughters had different views of their mothers and fathers, and were less positive towards their fathers particularly if he had posttraumatic stress disorder (PTSD). Veteran PTSD and depression significantly negatively impacted the family emotional climate, while mothers' mental health was not related. Veteran PTSD symptoms were lowest in secure attachment to the veteran and highest in inconsistent attachment for both sons and daughters, but were not related to attachment to the mother. Veteran PTSD was related to daughters' but not sons' perceptions of family emotional climate. The impact of veterans' PTSD on their families' emotional climate is more marked for daughters than sons.

Self-reported physician-diagnosed chronic obstructive pulmonary disease and spirometry patterns in Vietnam Era US Army Chemical Corps veterans: A retrospective cohort study

BACKGROUND

Research on chronic obstructive pulmonary disease (COPD) and herbicide exposure in Vietnam War veterans is limited.

METHODS

Survey data were collected from 3193 US Army Chemical Corps veterans on herbicide exposure and self-reported physician-diagnosed COPD. Three spirometric patterns were used to define airflow obstruction (AFO): (i) FEV₁ /FVC < 70% ("fixed ratio"); (ii) FEV₁ /FVC < lower limit of normal ("LLN"); and (iii) (FEV₁ /FVC < LLN and FVC ≥ LLN and FEV₁ <LLN) or (FEV₁ /FVC<LLN and FEV₁  ≥ LLN) ("specific obstruction"). Associations between herbicide exposure and self-reported COPD and spirometric-AFO were determined using regression.

RESULTS

COPD prevalence varied (self-reports: 20.1%; spirometry: 29.8%, 12.9%, 8.4% by fixed ratio, LLN, and specific obstruction definitions, respectively). Spirometric parameters did not differ by exposure. Self-reported COPD and herbicide exposure were significantly associated (adjusted odds ratio [aOR] = 1.82, 95% confidence intervaI: 1.48,2.24). No association was found between spirometric-AFO and herbicide exposure.

CONCLUSIONS

A significant association was found between herbicide exposure and self-reported physician-diagnosed COPD but not when COPD diagnosis was based on spirometry.

Evaluation of an equine-assisted therapy program for veterans who identify as 'wounded, injured or ill' and their partners

The aim of this study was to evaluate outcomes of an equine-assisted therapy program for Defence Force veterans and their partners across the psychological domains of depression, anxiety, stress, posttraumatic stress, happiness, and quality of life, as well as compare the outcomes of an Individual and Couples program. A non-controlled, within-subjects longitudinal design was utilized with assessment at three time points (pre-intervention, post-intervention, and three months follow-up). Between-subjects analysis with two groups was also conducted to compare the outcomes of the Individual and Couples programs. Participants were recruited from ten programs in 2016 with a total of 47 veterans and partners from both an Individual program (n = 25; veterans only) and a Couples program (n = 22). Outcome measures included the Depression Anxiety Stress Scale-21, Posttraumatic Stress Disorder Checklist for DSM-5, Oxford Happiness Questionnaire, and Quality-of-Life Enjoyment and Satisfaction Questionnaire-Short Form. Paired samples t-tests revealed that within both the Individual and Couples programs, there were significantly fewer psychological symptoms and significantly greater levels of happiness and quality of life at post-intervention compared to pre-intervention. Reduced psychological symptoms were maintained at the three months follow-up for participants of the Couples program only. Independent samples t-tests revealed participants in the Couples program reported significantly less symptoms of depression, stress, and posttraumatic stress disorder (PTSD) at follow-up compared to participants in the Individual program. These results indicate there may only be meaningful benefits for equine-assisted therapy in the reduction of depression, stress, and PTSD symptoms for veterans, if partners are integrated into the intervention.

Five Months Follow-up Study of School-based Crisis Intervention for Korean High School Students Who Experienced a Peer Suicide

BACKGROUND

The purpose of this study was to examine post-traumatic stress, depression, anxiety, and complicated grief in Korean high school students who experienced a peer suicide.

METHODS

A total of 956 students were included in the statistical analysis. One week after a peer suicide, a school-based crisis intervention program was conducted. The cohort was followed-up at one week and five months after a peer suicide. The program consists of screening tests, educational sessions, and further interview with psychiatric specialists for the selected group. Screening tests were conducted for all students to measure the Child Report of Post-traumatic Symptoms (CROPS), the post-traumatic stress symptoms (The University of California at Los Angeles post-traumatic stress disorder [PTSD] reaction index; UCLA-PTSD-RI), the anxiety symptoms (The Korean-Beck Anxiety Inventory; K-BAI), the depressive symptoms (The Korean-Beck Depression Inventory-II; K-BDI-II), and the complicated grief reaction (The Inventory of Complicated Grief; ICG). For statistical analysis, the SPSS Statistics 21.0 program was used.

RESULTS

At baseline and five months follow-ups, 8.6% and 2.9% of the students showed post-traumatic stress symptoms. At five months follow-up, there was a statistically significant decline in the post-traumatic stress symptoms, anxiety, depression, and complicated grief among the 'trauma group.' A higher proportion of the female students showed post-traumatic stress symptoms after the incident of peer suicide than the male students.

CONCLUSION

School-based crisis intervention helps improvement of trauma-related symptoms. It might be an effective way to prevent suicide spreading among students by alleviating trauma-related symptoms.

Factors associated with persistent posttraumatic stress disorder among U.S. military service members and veterans

BACKGROUND

Posttraumatic stress disorder (PTSD) can have long-term and far-reaching impacts on health and social and occupational functioning. This study examined factors associated with persistent PTSD among U.S. service members and veterans.

METHODS

Using baseline and follow-up (2001-2013) questionnaire data collected approximately every 3 years from the Millennium Cohort Study, multivariable logistic regression was conducted to determine factors associated with persistent PTSD. Participants included those who screened positive for PTSD using the PTSD Checklist-Civilian Version at baseline (N = 2409). Participants were classified as having remitted or persistent PTSD based on screening negative or positive, respectively, at follow-up.

RESULTS

Almost half of participants (N = 1132; 47%) met criteria for persistent PTSD at the first follow-up; of those, 804 (71%) also screened positive for PTSD at the second follow-up. Multiple factors were independently associated with persistent PTSD in an adjusted model at the first follow-up, including older age, deployment with high combat exposure, enlisted rank, initial PTSD severity, depression, history of physical assault, disabling injury/illness, and somatic symptoms. Among those with persistent PTSD at the first follow-up, additional factors of less sleep, separation from the military, and lack of social support were associated with persistent PTSD at the second follow-up.

CONCLUSIONS

Combat experiences and PTSD severity were the most salient risk factors for persistent PTSD. Comorbid conditions, including injury/illness, somatic symptoms, and sleep problems, also played a significant role and should be addressed during treatment. The high percentage of participants with persistent PTSD supports the need for more comprehensive and accessible treatment, especially after separation from the military.

Prospective Examination of Early Associations of Iraq War Zone Deployment, Combat Severity, and Posttraumatic Stress Disorder with New Incident Medical Diagnoses

War zone deployment and posttraumatic stress disorder (PTSD) have been associated with morbidity and mortality decades later. Less is known about the associations between these variables and the early emergence of medical disorders in war zone veterans. This prospective study of 862 U.S. Army soldiers (n = 569 deployed; n = 293 nondeployed) examined: (a) associations between Iraq War deployment status (deployed vs. nondeployed) and new medical diagnoses that emerged within six months after return from Iraq among all participants; and (b) associations between combat severity and PTSD symptoms, and new postdeployment medical diagnoses that emerged within 12 months after return from Iraq within deployed participants. New medical diagnoses were abstracted from diagnostic codes associated with clinical outpatient visits recorded within the Department of Defense Standard Ambulatory Data Record database. Combat severity was measured with the Combat Experiences module of the Deployment Risk and Resilience Inventory, and postdeployment posttraumatic stress disorder symptom severity was measured using the PTSD Checklist-Civilian. Neither deployment nor combat severity was associated with new medical diagnoses. However, among deployed soldiers, more severe PTSD symptoms were associated with increased risk for a new medical disorder diagnosis; every 10-point increase in PTSD symptoms increased odds of a new diagnosis by nearly 20% (odds ratio = 1.20). Results suggest that PTSD symptoms are associated with early morbidity in Iraq War veterans.

Veteran and military mental health: the Australian experience

Australia has deployed over 25 000 personnel to recent conflicts in the Middle East and has been involved in peacekeeping missions. Australian veterans report elevated rates of mental health problems such as post-traumatic stress disorder, anxiety disorders, affective disorders and substance use disorders. Veteran healthcare is delivered through publicly funded services, as well as through private services, at primary, secondary and tertiary levels. Some of the challenges involve coordination of services for veterans transitioning from Defence to Veterans' Affairs, service delivery across a large continent and stigma inhibiting service-seeking. Initiatives have been introduced in screening and delivery of evidence-based treatments. While challenges remain, Australia has come a long way towards an integrated and comprehensive approach to veteran mental healthcare.

Post-traumatic stress disorder in adult victims of cluster munitions in Lebanon: a 10-year longitudinal study

OBJECTIVE

This study aims to explore the short-term and long-term prevalence and effects of post-traumatic stress disorder (PTSD) among victims of cluster munitions.

DESIGN AND SETTING

A prospective 10-year longitudinal study that took place in Lebanon.

PARTICIPANTS

Two-hundred-and-forty-four Lebanese civilian victims of submunition blasts, who were injured in 2006 and were over 18 years old, were interviewed. Included were participants who had been diagnosed with PTSD according to the Diagnostic and Statistical Manual of Mental Disorders, 5th Edition (DSM-5) and the PTSD Checklist - Civilian Version in 2006. Interviewees were present for the 10-year follow-up.

MAIN OUTCOME MEASURES

PTSD prevalence rates of participants in 2006 and 2016 were compared. Analysis of the demographical data pertaining to the association of long-term PTSD with other variables was performed. p Values <0.05 were considered statistically significant for all analyses (95% CI).

RESULTS

All the 244 civilians injured by cluster munitions in 2006 responded, and were present for long-term follow-up in 2016. The prevalence of PTSD decreased significantly from 98% to 43% after 10 years (p<0.001). A lower long-term prevalence was significantly associated with male sex (p<0.001), family support (p<0.001) and religion (p<0.001). Hospitalisation (p=0.005) and severe functional impairment (p<0.001) post-trauma were significantly associated with increased prevalence of long-term PTSD. Symptoms of negative cognition and mood were more common in the long run. In addition, job instability was the most frequent socioeconomic repercussion among the participants (88%).

CONCLUSIONS

Psychological symptoms, especially PTSD, remain high in war-affected populations many years after the war; this is particularly evident for Lebanese civilians who were victimised by cluster munitions. Screening programmes and psychological interventions need to be implemented in vulnerable populations exposed to war traumas. Officials and public health advocates should consider the socioeconomic implications, and help raise awareness against the harm induced by cluster munitions and similar weaponry.

The impact of potentially traumatic events on the mental health of males who have served in the military: Findings from the Australian National Survey of Mental Health and Wellbeing

OBJECTIVE

The study investigated the impact of potentially traumatic events on mental health outcomes among males who had ever served in the Australian Defence Force.

METHOD

Data from a nationally representative household survey of Australian residents, the 2007 National Survey of Mental Health and Wellbeing, were used for this study.

RESULTS

Compared with community members, Australian Defence Force males were significantly more likely to have experienced not only deployment and other war-like events but also accidents or other unexpected events, and trauma to someone close. For non-deployed males, Australian Defence Force members were at increased risk of accidents or other unexpected events compared to community members. After controlling for the effect of potentially traumatic events that were more prevalent among all Australian Defence Force members, the increased risk of mental disorders among Australian Defence Force members was no longer evident. For non-deployed males, Australian Defence Force and community members were at comparable risk of poor mental health outcomes. A significant minority of Australian Defence Force members had onset of a mental disorder prior to their first deployment.

CONCLUSIONS

Deployment and other potentially traumatic events among Australian Defence Force members can help to explain their increased vulnerability to mental disorders compared with community members. Providers should routinely enquire about a range of potentially traumatic events among serving and ex-serving military personnel.

Intergenerational transmission of post-traumatic stress disorder in Australian Vietnam veterans' families

OBJECTIVE

To assess the association between parental post-traumatic stress disorder (PTSD) and offspring PTSD and its specificity for other disorders in a non-clinical epidemiological cohort of Australian Vietnam veterans, their partners and their sons and daughters.

METHOD

Veterans were interviewed twice, in 1992-1994 and 2005-2006; partners were interviewed in 2006-2007, and their offspring in 2012-2014. A total of 125 sons and 168 daughters were interviewed from 197 families, 137 of which also included partners who were the mothers of the children. Statistical analysis used multi-level modelling to compute odds ratios and 95% confidence intervals while controlling for clustering effects within families. Parent PTSD diagnoses were examined for associations with offspring trauma exposure, PTSD and other psychiatric diagnoses.

RESULTS

Veteran PTSD increased the risk of PTSD and no other disorder in both sons and daughters; partner PTSD did not. Veteran depression was also a risk factor for sons' PTSD, and alcohol disorder was linked to alcohol dependence in sons and PTSD in daughters, but not when controlling for veteran PTSD.

CONCLUSION

We conclude that PTSD in a Vietnam veteran father increases the risk specifically for PTSD in his sons and daughters.

The Course and Correlates of Combat-Related PTSD in Australian Vietnam Veterans in the Three Decades After the War

Australian male Vietnam veterans (N = 388) were assessed 22 and 36 years after their return to Australia using standardized diagnostic interviews, with added data from Army records and self-report questionnaires. Among veterans who ever had posttraumatic stress disorder (PTSD), 50.3% had a current diagnosis at the second assessment; of those who had a current diagnosis at Wave 1, 46.9% were also current at Wave 2. Late onset occurred for 19.0% of veterans, of whom 60.8% were current at Wave 2. Multivariate analysis compared veterans with no history of PTSD (n = 231) with veterans who had ever had PTSD (n = 157) to assess risk factors for PTSD incidence; and veterans with a history, but not current PTSD (n = 78) with veterans who had current PTSD at the second assessment (n = 79) to assess risk factors for failure to remit. Incidence was associated with lower education, shorter Army training predeployment, higher combat, excess drinking, and help-seeking after return to Australia. Prevalence was associated with having a father who saw combat in World War II, being injured in battle, having a lower intelligence test score, experiencing higher combat, and having a diagnosis of phobia at the first assessment. Only combat was common to incidence and prevalence.

A psychometric evaluation of hierarchical and oblique versions of five variants of the Posttraumatic Growth Inventory

The Posttraumatic Growth Inventory (PTGI; Tedeschi and Calhoun, 1996) is the most commonly used measure of posttraumatic growth. Although the original five factor structure has extensive psychometric support, evidence exists for alternate PTGI models. The current study assessed the validity of oblique and hierarchical factor structures of five PTGI models. Confirmatory factor analyses were performed among a heterogeneous community sample with a diverse trauma history. The oblique models provided a better fit to the data compared with their respective hierarchical models. Three oblique variants provided good fit to the data on two fit indices and all five oblique variants met the recommended criteria for at least one fit index. The 10-item model demonstrated the lowest Expected Cross-Validation Index (ECVI) values and is a brief and useful measure when examining PTGI total scores; however, current results suggest that consideration of the specific subscales may be more meaningful than total scores. Researchers and clinicians interested in subscale scores should consider using the 18- or 21-item variants due to a higher number of items per factor and, therefore, greater factor stability. Future directions in refining and measuring posttraumatic growth are discussed.

Risk of depressive disorder following disasters and military deployment: systematic review with meta-analysis

BACKGROUND

Numerous studies describe the occurrence of post-traumatic stress disorder following disasters, but less is known about the risk of major depression.

AIMS

To review the risk of depressive disorder in people surviving disasters and in soldiers returning from military deployment.

METHOD

A systematic literature search combined with reference screening identified 23 controlled epidemiological studies. We used random effects models to compute pooled odds ratios (ORs).

RESULTS

The average OR was significantly elevated following all types of exposures: natural disaster OR = 2.28 (95% CI 1.30-3.98), technological disaster OR = 1.44 (95% CI 1.21-1.70), terrorist acts OR = 1.80 (95% CI 1.38-2.34) and military combat OR = 1.60 (95% CI 1.09-2.35). In a subset of ten high-quality studies OR was 1.41 (95% CI 1.06-1.87).

CONCLUSIONS

Disasters and combat experience substantially increase the risk of depression. Whether psychological trauma per se or bereavement is on the causal path is unresolved.

Cognitive-behavioral group treatment for veterans diagnosed with PTSD: Design of a hybrid efficacy-effectiveness clinical trial

Despite significant advances in individual treatment approaches for PTSD, knowledge of group approaches has lagged behind. Much of the reason knowledge about group treatment for PTSD has been limited is due to the complexity of conducting randomized controlled trials in the group treatment context. This limited empirical knowledge is unfortunate given the frequency with which group treatment for PTSD is used in clinical settings, including the Department of Veteran Affairs. The goal of this study is to examine the efficacy of a group cognitive-behavioral treatment (GCBT) for PTSD relative to group supportive counseling approach (i.e. group present centered treatment; GPCT). The sample consists of 196 veterans diagnosed with PTSD who are randomly assigned to either GCBT (n=98) or GPCT (n=98). Both treatments are administered by two therapists over the course of 14 sessions. Assessments take place at baseline, mid-treatment, post-treatment and 3-, 6-, and 12-month follow-up. The primary outcome measure is the PTSD symptom severity assessed with a semi-structured diagnostic instrument. Given the substantial rise of veterans presenting for PTSD treatment services, identifying an efficacious group treatment approach is invaluable.

Long-term health effects of Vietnam-era military service: A quasi-experiment using Australian conscription lotteries

This paper estimates the long-term health effects of Vietnam-era military service using Australia's National conscription lotteries for identification. Our primary contribution is the quality and breadth of our health outcomes. We use several administrative sources, containing a near-universe of records on mortality (1994-2011), cancer diagnoses (1982-2008), and emergency hospital presentations (2005-2010). We also analyse a range of self-reported morbidity indicators (2006-2009). We find no significant long-term effects on mortality, cancer or emergency hospital visits. In contrast, we find significant detrimental effects on a number of morbidity measures. Hearing and mental health appear to be particularly affected.

The long-term mental health impact of peacekeeping: prevalence and predictors of psychiatric disorder

BACKGROUND

The mental health outcomes of military personnel deployed on peacekeeping missions have been relatively neglected in the military mental health literature.

AIMS

To assess the mental health impacts of peacekeeping deployments.

METHOD

In total, 1025 Australian peacekeepers were assessed for current and lifetime psychiatric diagnoses, service history and exposure to potentially traumatic events (PTEs). A matched Australian community sample was used as a comparator. Univariate and regression analyses were conducted to explore predictors of psychiatric diagnosis.

RESULTS

Peacekeepers had significantly higher 12-month prevalence of post-traumatic stress disorder (16.8%), major depressive episode (7%), generalised anxiety disorder (4.7%), alcohol misuse (12%), alcohol dependence (11.3%) and suicidal ideation (10.7%) when compared with the civilian comparator. The presence of these psychiatric disorders was most strongly and consistently associated with exposure to PTEs.

CONCLUSIONS

Veteran peacekeepers had significant levels of psychiatric morbidity. Their needs, alongside those of combat veterans, should be recognised within military mental health initiatives.

Health conditions in a cohort of New Zealand Vietnam veterans: hospital admissions between 1988 and 2009

OBJECTIVES

To inform the provision of support to veterans by analysing hospital discharge data, thereby identifying which conditions show an excess risk, require specific management strategies and deserve further investigation.

SETTING

Tertiary level care, including all public and private New Zealand hospitals.

PARTICIPANTS

All New Zealand Vietnam veterans with service between 1964 and 1972.

PRIMARY OUTCOME MEASURES

Standardised hospitalisation ratios (SHRs) were calculated based on the number of first observed hospital admissions for a condition, those expected being based on New Zealand national hospitalisation rates.

RESULTS

The SHR for all causes of hospitalisation was 1.18, 95% CI 1.15 to 1.21, with modest increases for the major common causes, cardio and cerebrovascular disease. Admission rates for chronic renal failure and chronic obstructive pulmonary disease were highest in the 2006-2009 time period. The highest statistically significant hospitalisation risk was for alcohol-related mental disorder, SHR 1.91, 99% CI 1.39 to 2.43.

CONCLUSIONS

Chronic renal failure has limited attribution to veteran service but along with chronic obstructive pulmonary disease has the potential to have high costs both to the individual and the health system. We suggest that routine surveillance of veterans by way of a 'flag' in national and primary care databases would facilitate the recognition of service-related conditions and the appropriate provision of healthcare.

Temporal Associations Among Chronic PTSD Symptoms in U.S. Combat Veterans

The present study examined fluctuation over time in symptoms of posttraumatic stress disorder (PTSD) among 34 combat veterans (28 with diagnosed PTSD, 6 with subclinical symptoms) assessed every 2 weeks for up to 2 years (range of assessments = 13-52). Temporal relationships were examined among four PTSD symptom clusters (reexperiencing, avoidance, emotional numbing, and hyperarousal) with particular attention to the influence of hyperarousal. Multilevel cross-lagged random coefficients autoregression for intensive time series data analyses were used to model symptom fluctuation decades after combat experiences. As anticipated, hyperarousal predicted subsequent fluctuations in the 3 other PTSD symptom clusters (reexperiencing, avoidance, emotional numbing) at subsequent 2-week intervals (rs = .45, .36, and .40, respectively). Additionally, emotional numbing influenced later reexperiencing and avoidance, and reexperiencing influenced later hyperarousal (rs = .44, .40, and .34, respectively). These findings underscore the important influence of hyperarousal. Furthermore, results indicate a bidirectional relationship between hyperarousal and reexperiencing as well as a possible chaining of symptoms (hyperarousal → emotional numbing → reexperiencing → hyperarousal) and establish potential internal, intrapersonal mechanisms for the maintenance of persistent PTSD symptoms. Results suggested that clinical interventions targeting hyperarousal and emotional numbing symptoms may hold promise for PTSD of long duration.
