Lifetime and current prevalence of specific psychiatric disorders among Vietnam veterans and controls

A protocol for a randomized controlled trial of exposure and response prevention for veterans with obsessive compulsive disorder

BACKGROUND

Obsessive compulsive disorder (OCD) is effectively treated with exposure and response prevention (ERP), yet very few veterans receive ERP for OCD within the Veterans Health Administration (VHA). Veterans are a clinically complex population, and no prior research has evaluated the effectiveness of ERP in veterans with OCD or comorbid OCD and posttraumatic stress disorder (PTSD). Given the limited accessibility of ERP-trained providers within VHA, assessment of video telehealth (VTH) delivery of ERP is warranted.

METHODS

A sample of 160 veterans with OCD (80 diagnosed with comorbid PTSD) will be randomly assigned to receive up to 16 sessions of ERP or a stress management training control delivered via VTH. Assessments will occur at baseline, posttreatment, and 6-month follow-up. The primary outcome will evaluate the impact of ERP on participants' functioning, and secondary outcomes will include quality of life and OCD symptoms. At posttreatment, qualitative interviews with veterans, clinicians, and administrators will explore barriers and facilitators to treatment delivery, and the implementation potential of ERP.

CONCLUSIONS

Results will provide direction for the treatment of OCD and comorbid PTSD in veterans, as well as guidance for future implementation efforts for ERP within VHA.

Effects of trauma history on cancer-related screening, diagnosis, and treatment

Trauma has substantial effects on human health and is recognised as a potential barrier to seeking or receiving cancer care. The evidence that exists regarding the effect of trauma on seeking cancer screening, diagnosis, and treatment and the gaps therein can define this emerging research area and guide the development of interventions intended to improve the cancer care continuum for trauma survivors. This Review summarises current literature on the effects of trauma history on screening, diagnosis, and treatment among adult patients at risk for or diagnosed with cancer. We discuss a complex relationship between trauma history and seeking cancer-related services, the nature of which is influenced by the necessity of care, perceived or measured health status, and potential triggers associated with the similarity of cancer care to the original trauma. Collaborative scientific investigations by multidisciplinary teams are needed to generate further clinical evidence and develop mitigation strategies to provide trauma-informed cancer care for this patient population.

Substance Use in U.S. Vietnam War Era Veterans and Nonveterans: Results from the Vietnam Era Health Retrospective Observational Study

Background: Substance use (SU) is associated with physical injury and mental health disorders in older persons, but recent research has scarcely examined SU in U.S. Vietnam-era veterans who are mostly in or near their eighth decade of life. Objectives: We compared the prevalence of self-reported lifetime and current SU and modeled current usage patterns in a nationally representative sample of veterans versus a matched nonveteran cohort. Methods: Cross-sectional, self-reported survey data were analyzed from the 2016-2017 Vietnam Era Health Retrospective Observational Study (VE-HEROeS) (n = 18,866 veterans, n = 4,530 nonveterans). We assessed lifetime and current alcohol and drug use disorders; lifetime and current use of cannabis, opioids, stimulants, sedatives, "other drugs" (psychedelics, prescription or over-the-counter drugs not prescribed/used as intended); and current SU patterns (alcohol-use-only, drug-use-only, dual-SU, no SU). Weighted descriptive, bivariable, and multivariable statistics were calculated. Covariates in multinomial modeling included sociodemographic characteristics, lifetime cigarette smoking, depression, potentially traumatic events (PTEs), and current pain (SF-8^TM). Results: Prevalence of lifetime opioid and sedative use (p ≤ .01), drug and alcohol use disorders (p < .001), and current "other drug" use (p < .001) were higher in veterans versus nonveterans. Current use of alcohol and cannabis was high in both cohorts. In veterans, very severe/severe pain, depression, and PTEs were highly associated with drug-use-only (p < .001) and dual-SU (p < .01), but these associations were fewer for nonveterans. Conclusion: This research confirmed existing concerns over substance misuse in older individuals. Vietnam-era veterans may be at particular risk due to service-related experiences and later-life tribulations. Era veterans' unique perceptions toward healthcare assistance for SU may need greater provider focus to maximize self-efficacy and treatment.

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

PURPOSE

The COVID-19 pandemic has had a profound impact on mental health around the world. Although there have been reports that the incidence of eating disorders (EDs) has increased during the pandemic, few longitudinal studies have examined recent changes in EDs. Men and women with military histories may be particularly vulnerable to EDs, underscoring the importance of investigating the impact of the COVID-19 pandemic on EDs in this population.

METHOD

We examined whether early-pandemic (Time 1; T1) posttraumatic stress disorder, depression, anxiety, and stress symptoms were associated with change in probable ED diagnostic status 1 year later (T2). We also investigated relationships from early pandemic mental health symptoms to change in ED diagnostic status from T1 to T2 via pandemic-related life circumstance pathways (health, financial, social, etc.). Participants included a population-based sample of 372 U.S. veterans who completed the T1 and T2 surveys.

RESULTS

Early pandemic mental health was significantly and positively associated with probable ED diagnostic status. Social and health satisfaction as well as physical health pandemic impacts mediated the associations between mental health symptoms and ED diagnostic status.

DISCUSSION

Findings highlight the importance of bolstering social connection, health-promoting behaviors, and access to ED treatment among veteran men and women impacted by the COVID-19 pandemic.

PUBLIC SIGNIFICANCE

The COVID-19 pandemic has had a profound impact on mental health, including eating disorders (EDs). We found that early pandemic mental health symptoms were significantly associated with changes in U.S. veterans' ED diagnostic status 1 year later. Mental health symptoms increased ED diagnoses via their impact on social and health satisfaction, as well as physical health impacts of the pandemic. Findings highlight the importance of increasing social connection, health-promoting behaviors, and ED treatment access among veteran men and women, who may be particularly vulnerable to EDs, during the COVID pandemic.

The 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.

Behavioral Epidemic of Loneliness in Older U.S. Military Veterans: Results From the 2019-2020 National Health and Resilience in Veterans Study

OBJECTIVE

This study aimed to characterize the current prevalence of loneliness, and the relation between loneliness severity and mental and physical health conditions, suicidality, and functional measures in a predominantly older sample of U.S. military veterans.

METHODS

This cross-sectional study used data from the National Health and Resilience in Veterans Study, which surveyed a nationally representative sample of U.S. veterans (N = 4,069; mean age = 62) from November 2019 through March 2020. Veterans were classified into one of 3 groups based on their current level of loneliness (hardly ever, sometimes, often) on an adapted version of the Revised UCLA Loneliness Scale. A comprehensive range of mental and physical health, and functioning variables were assessed using valid and reliable self-report assessments.

RESULTS

A total of 56.9% of veterans endorsed feeling lonely sometimes (37.2%) or often (19.7%). Loneliness severity was independently associated with a range of mental health (odds ratios [ORs] = 1.21-33.30), physical health (ORs = 1.21-6.80), and functional difficulties (d's = 0.09-0.59). Relative to hardly ever feeling lonely, feeling lonely often or sometimes was associated with a more than 12- and three-fold greater likelihood of current suicidal ideation (29.0% versus 7.3% versus 1.5%), even after adjustment for sociodemographic, military, and psychiatric risk factors.

CONCLUSIONS

Loneliness is highly prevalent in U.S. military veterans, with more than half endorsing feeling lonely sometimes or often, and 1-of-5 reporting feeling lonely often. Loneliness severity was independently associated with a broad range of mental and physical health and functional measures, ias well as suicidal ideation. Results underscore the importance of loneliness as a transdiagnostic prevention and intervention target in the U.S. veteran population.

Reciprocal effects between depressive symptoms and pain in veterans over 50

OBJECTIVE

Depression and chronic pain are major problems in American veterans, yet there is limited long-term research examining how they relate to one another in this population. This study examined the relationship between depressive symptoms and pain in U.S. veterans aged 50+.

METHODS

This study used data on veterans from the 2002-2016 waves of the Health and Retirement Study (n = 4,302), a large-scale observational study of Americans aged 50+. Measures included a short form of the Center for Epidemiologic Studies Depression scale and two items assessing the presence and degree of pain. Analyses included random intercept cross-lagged panel models (RI-CLPM).

RESULTS

In the RI-CLPM, there were roughly equivalent cross-lagged effects between depressive symptoms and pain. There was also evidence that depressive symptoms and pain have a trait-like component and that these trait-like characteristics are associated.

CONCLUSIONS

These findings indicate that depressive symptoms and pain in veterans are stable characteristics in American veterans over 50. There appear to be reciprocal effects between the two, whereby deviations in one's typical depressive symptoms predict subsequent deviations in one's pain level and vice-versa; however, the size of these effects is very small. These findings suggest that clinicians should treat both depressive symptoms and pain, rather than assume that treatment benefits in one domain will lead to major benefits in another.

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 (β=0.23) and lifetime PTSD symptom severity (β=0.19), particularly re-experiencing symptoms (β=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 (β=0.15) and QOL (β=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.

Differences in functional and structural social support among female and male veterans and civilians

PURPOSE

Social support is an important correlate of health behaviors and outcomes. Studies suggest that veterans have lower social support than civilians, but interpretation is hindered by methodological limitations. Furthermore, little is known about how sex influences veteran-civilian differences. Therefore, we examined veteran-civilian differences in several dimensions of social support and whether differences varied by sex.

METHODS

We performed a cross-sectional analysis of the 2012-2013 National Epidemiologic Survey of Alcohol and Related Conditions-III, a nationally representative sample of 34,331 respondents (male veterans = 2569; female veterans = 356). We examined veteran-civilian differences in functional and structural social support using linear regression and variation by sex with interactions. We adjusted for socio-demographics, childhood experiences, and physical and mental health.

RESULTS

Compared to civilians, veterans had lower social network diversity scores (difference [diff] = - 0.13, 95% confidence interval [CI] - 0.23, - 0.03). Among women but not men, veterans had smaller social network size (diff = - 2.27, 95% CI - 3.81, - 0.73) than civilians, attributable to differences in religious groups, volunteers, and coworkers. Among men, veterans had lower social network diversity scores than civilians (diff = - 0.13, 95% CI - 0.23, - 0.03); while among women, the difference was similar but did not reach statistical significance (diff = - 0.13, 95% CI - 0.23, 0.09). There was limited evidence of functional social support differences.

CONCLUSION

After accounting for factors that influence military entry and social support, veterans reported significantly lower structural social support, which may be attributable to reintegration challenges and geographic mobility. Findings suggest that veterans could benefit from programs to enhance structural social support and improve health outcomes, with female veterans potentially in greatest need.

Depression and/or PTSD Comorbidity Affects Response to Antidepressants in Those With Alcohol Use Disorder

Objective: Depression and post-traumatic stress disorder (PTSD) highly co-occur with alcohol use disorder (AUD). The comparative effects of noradrenergic vs. serotonergic antidepressants on drinking and depressive outcomes for those with AUD and co-occurring depression and/or PTSD are not well known. Methods: This study was an analysis of a randomized control trial of 128 patients with AUD who had co-occurring depression and/or PTSD. They were randomized to treatment with paroxetine vs. desipramine and naltrexone vs. placebo leading to four groups: paroxetine plus naltrexone, paroxetine plus placebo, desipramine plus naltrexone, and desipramine plus placebo. Outcomes were percent of drinking days, percent heavy drinking days, drinks per drinking day (Time Line Follow-back Method), and depressive symptoms (Hamilton Depression Scale). Groups compared were (1) depression without PTSD (depression group; n = 35), (2) PTSD without depression (PTSD group; n = 33), and (3) both depression and PTSD (comorbid group; n = 60). Results: There were no overall significant differences in drinking outcomes by medication in the entire sample, and no significant interaction when diagnostic groups were not considered. However, when diagnostic groups were included in the model, the interactions between time, diagnostic group, and medication (desipramine vs. paroxetine) were significant for percent drinking days (p = 0.042), and percent heavy drinking days (p = 0.036); paroxetine showed better drinking outcomes within the depression group, whereas desipramine showed better drinking outcomes in the PTSD and comorbid groups. Regarding depressive symptoms, paroxetine was statistically superior to desipramine in the total sample (p = 0.007), but there was no significant interaction of diagnostic group and medication. Naltrexone led to a decrease in craving but no change in drinking outcomes. Conclusions: The results of this study suggest that drinking outcomes may respond differently to desipramine and paroxetine depending on comorbid MDD and/or PTSD.

Donepezil and cognitive remediation therapy to augment treatment of alcohol use disorder related mild cognitive impairment (AUD-MCI): An open label pilot study with historical controls

BACKGROUND

Pharmacological and psychosocial interventions have only modest efficacy for Alcohol Use Disorder (AUD), and continued alcohol use has brain effects on neurocognition, which place heavy drinkers at increased risk of early onset dementia. The most common neurocognitive deficits are in the domains of executive function and memory, and these deficits may impact AUD treatment outcomes. AUD related Mild Cognitive Impairment (AUD-MCI) is a diagnosis in DSM-V and ICD-10. Donepezil, a cholinesterase inhibitor, is currently FDA approved for treatment of dementia, and recent preclinical research suggests anticholinesterase agents may treat alcoholism. Another approach to cognitive recovery is Cognitive Remediation Therapy (CRT). Recent research supports CRT efficacy in schizophrenia and related disorders, and some research suggests that CRT could improve neurocognition in substance abuse disorders (SUDs). This is the first report of an open-label clinical trial that combined donepezil with CRT to improve neurocognitive and clinical outcomes in the early phase of AUD recovery. Methods: Eleven older male US Veterans with AUD-MCI as determined by Level II neurocognitive criteria and who had recently relapsed participated in an open-label trial of 13 weeks of donepezil combined with CRT. They were compared with matched historical control samples on neurocognitive and clinical outcomes. Results: Participants had excellent adherence to donepezil and CRT. Neurocognitive improvements were highly significant on a composite score of learning and memory and executive function measures (p < .0001) and was significantly better than historical matched controls (p < .001). On a Clinical Global Impression scale, 90.9% of participants had a good clinical recovery compared with 59.5% of historical matched controls (p <.052). Conclusions: AUD-MCI has not received much research attention but is of considerable public health importance. Findings in this open-label trial of donepezil + CRT should encourage further investigation into the clinical benefit of this combined treatment for AUD-MCI.

Transitions in alcohol use over time: a survival analysis

Background

The current study examined the predictors of the onset of alcohol use as well as predictors of remission and relapse, both from heavy drinking and from alcohol dependence. Similarities and differences in both clinical and psychosocial predictors across the transitions were examined.

Methods

A sample of men from the Vietnam Era Twin Registry (N = 1769) completed an assessment of lifetime drinking history, which allowed age markers for starting and stopping different drinking patterns. The men also completed various assessments regarding personality, alcohol motives, and psychiatric diagnoses. Survival analyses were used to examine the predictors of the three transitions of onset, remission, and relapse for the phenotypes of heavy drinking and of alcohol dependence, censoring the individuals who had not yet experienced an event.

Results

As expected, predictors of onset for drinking, heavy drinking, and alcohol dependence were largely consistent and included externalizing symptomology, nicotine dependence, and cotwin history of drinking as risk factors. Predictors of remission from heavy drinking, somewhat similarly to remission from alcohol dependence, included the risk factor of externalizing disorders but also, as predicted, included more risk and protective factors in the psychosocial realm that were not predictors of onset. Contrary to our prediction, relapse to heavy drinking and alcohol dependence were predicted largely by unique psychosocial risk and protective factors including social and coping motives.

Conclusion

Current findings extend the findings of past research to remission and relapse in the later decades of life and have implications for treatment of alcohol use problems.

A Descriptive Study of Transgender Active Duty Service Members in the U.S. Military

Purpose: Department of Defense policy prohibits, with limited exceptions, transgender individuals from serving in their affirmed gender in the U.S. Military, citing potential impact on unit cohesion and military readiness. To date, however, little is known about the sociodemographic profile and health of transgender military personnel. Methods: U.S. Military personnel who self-identified as transgender completed anonymous online measures of demographics and military service. Participants also completed measures of health, mood, eating pathology, and risk behaviors. Results: One hundred ninety-five service members (mean age: 28.9±7.2 years, 48.7% transmale, 70.3% non-Hispanic White, 7.83±5.9 years in service) completed the survey. The majority of respondents first identified as transgender before military accession. Most had disclosed their gender identity to their command and providers, and had undertaken steps toward gender affirmation. The sample as a whole reported above average physical health, with mood symptoms within normal ranges and few reported risk behaviors. Analyses of covariance indicated that transmales reported significantly better mental health and psychosocial functioning compared with transfemales. Conclusion: In light of current policy that precludes, with limited exceptions, transgender individuals from serving in the U.S. Military in their affirmed gender, the current study provides an initial sociodemographic profile of this understudied population and indicates that transgender service members report above average physical health and few risk behaviors. Preliminary analyses indicated that transfemales in the military may be at higher risk for mental health concerns, compared with transmales. Additional research is needed to elucidate risk and protective factors among transgender service members.

Post-Traumatic Stress Disorder among Survivors of the September 11, 2001 World Trade Center Attacks: A Review of the Literature

Prior reviews of 9/11-related post-traumatic stress disorder (PTSD) have not focused on the civilian survivors most directly exposed to the attacks. Survivors include those individuals who were occupants of buildings in or near the World Trade Center (WTC) towers, those whose primary residence or workplace was in the vicinity, and persons who were on the street passing through the area. This review reports published information on the prevalence of and risk factors for PTSD, as well as comorbidities associated with PTSD among 9/11 survivors. Articles selected for inclusion met the following criteria: (1) full-length, original peer-reviewed empirical articles; (2) published in English from 2002-2019; (3) collected data from persons directly exposed; (4) adult populations; and (5) focused on non-rescue or recovery workers (i.e., survivors). Data were extracted with focus on study design, sample size, time frame of data collection post-9/11, PTSD assessment instrument, and PTSD prevalence, risk factors, and comorbidities. Our review identified the use of cross-sectional and longitudinal designs, finding multiple direct comorbidities with PTSD, as well as the prevalence and persistence of PTSD. Future research would benefit from incorporating more mixed methods designs, and exploring the mediating mechanisms and protective factors of the known associations of PTSD among the 9/11 survivor population.

Perceived Stress in Relation to Obsessions and Compulsions in South Asian Adults: Moderating Role of Socio-demographic Characteristics

This study examines perceived stress associated with obsessions and compulsions (OC) in a normative sample of adults. The aim was to discover whether socio-demographic characteristics (i.e., gender, marital status, employment status, age and education) had a moderating effect on perceived stress and OC symptoms. The participants were 362 Pakistani adults (M age = 26.82 years, SD = 4.75; males = 188, females = 174) and the findings were based on a demographic questionnaire, the perceived stress scale (Cohen et al., in Applied multiple correlation/regression analysis for the behavioral sciences, Taylor & Francis, London, 1983), and the Padua inventory of obsessive compulsion disorder symptoms (Burns et al., in Behav Res Ther, 34(2), 163-173, 1996). A series of stepwise regression analyses showed that socio-demographic characteristics (employment status, age, and education) significantly moderated the relationship between perceived stress and OC symptoms. The current findings have implications for clinicians and researchers in generating effective stress management programs and learning mechanism for managing OC symptoms, particularly in the context of socio-demographic characteristics.

Mental disorders and medical conditions associated with causing injury or death: A population-based study

The aim of the present study is to examine mental disorders and medical conditions associated with causing harm to another person in the general adult population. The sample (n=22,138) was drawn from a cross-sectional survey designed to characterize mental health needs in France. Twelve-month DSM-IV axis I mental disorders and medical conditions, and lifetime occurrence of potentially traumatic events were assessed with the Composite International Diagnostic Interview-SF Overall, 2% (n=430) of the sample reported having injured or killed someone. Causing harm was associated with male gender, lower education level, and being unemployed. The great majority (85%) of those who caused harm had experienced two or more additional potentially traumatic events. When adjusting for gender, employment status, education and number of events experienced, causing harm was associated with certain anxiety disorders, drug dependence and lifetime suicide attempt but not with major depression or post-traumatic stress disorder. Furthermore, causing harm was not associated with medical conditions in multivariate analyses. These results highlight the need for clinicians to be particularly attentive to the psychological burden that may be experienced by those who have harmed or killed someone.

The association of insomnia and sleep apnea with deployment and combat exposure in the entire population of US army soldiers from 1997 to 2011: a retrospective cohort investigation

Since 2001, the United States has been engaged in the longest and most expensive overseas conflict in its history. Sleep disorders, especially insomnia and obstructive sleep apnea (OSA), are common in service members and appear related to deployment and combat exposure, but this has not been systematically examined. Therefore, the incidence of clinically diagnosed insomnia and OSA from 1997 to 2011 in the entire population of US Army soldiers was determined and associations of these disorders with deployment and combat exposure examined. This observational retrospective cohort study linked medical, demographic, deployment, and combat casualty data from all active duty US Army soldiers serving from 1997 to 2011 (n = 1 357 150). The mediating effects of multiple known comorbid conditions were considered. From 2003 to 2011, there were extraordinary increases in incidence of insomnia (652%) and OSA (600%). Factors increasing insomnia risk were deployment (risk ratio [RR] [deployed/not deployed] = 2.06; 95% confidence interval [CI], 2.04-2.08) and combat exposure (RR [exposed/not exposed] = 1.20; 95% CI, 1.19-1.22). Risk of OSA was increased by deployment (RR [deployed/not deployed] = 2.14; 95% CI, 2.11-2.17), but not combat exposure (RR [exposed/not exposed] = 1.00; 95% CI, 0.98-1.02). These relationships remained after accounting for other factors in multivariable analyses. A number of comorbid medical conditions such as posttraumatic stress disorder and traumatic brain injury mediated a portion of the association between the sleep disorders and deployment. It is essential to determine underlying mechanisms responsible for these very large increases in insomnia and OSA and introduce effective preventive measures.

Post-Traumatic Stress Disorder is Associated with further Increased Parkinson's Disease Risk in Veterans with Traumatic Brain Injury

OBJECTIVE

Determining if traumatic brain injury (TBI) and post-traumatic stress disorder (PTSD) are risk factors for Parkinson's disease (PD). This constitutes a research priority for the Veterans Administration (VA) with implications for screening policy and prevention.

METHODS

Population-based, matched case-control study among veterans using VA health care facilities from October 1, 1999, to September 30, 2013. We identified 176,871 PD cases and 707,484 randomly selected PD-free matched controls. PD, TBI, and PTSD were ascertained by validated International Classification of Disease 9th revision (ICD)-9 code-based algorithms. We examined the association between both risk factors and PD using race-adjusted conditional logistic regression.

RESULTS

The overall study cohort prevalence for TBI_mild , TBI_non-mild , and PTSD was 0.65%, 0.69%, and 5.5%, respectively. Both TBI and PTSD were significantly associated with PD in single-risk factor race-adjusted analyses (conditional odds ratio [cOR] = 2.99; 95% confidence interval [CI]: 2.69-3.32), 3.82 (95% CI: 3.67-3.97), and 2.71 (95% CI: 2.66-2.77) for TBI_mild , TBI_non-mild , and PTSD, respectively). There was suggestive positive interaction observed with comorbid PTSD/TBI in dual-risk factor analyses, with significant 2.69-fold and 3.70-fold excess relative PD risk in veterans with TBI_mild and TBI_non-mild versus those without TBI when PTSD was present versus 2.17-fold and 2.80-fold excess risk when PTSD was absent.

INTERPRETATION

Our study was the first to demonstrate that both TBI and PTSD are independently associated with increased relative PD risk in a diverse nationwide cohort of military service veterans, and the first to suggest a potential modest synergistic excess risk in those with comorbid TBI/PTSD. Longitudinal research is needed to confirm these suggestive findings. ANN NEUROL 2020 ANN NEUROL 2020;88:33-41.

Comorbidity in post-traumatic stress disorder: A population-based study from the two largest cities in Brazil

BACKGROUND

This study investigated the patterns of comorbidity between PTSD and depression, other anxiety disorders, alcohol-related disorders using the DSM-IV and ICD-10 criteria. The temporal sequence of the comorbid diagnoses was also investigated.

METHODS

We used data from a large population-based survey carried out between 2007 and 2008 in the two largest cities in Brazil: São Paulo and Rio de Janeiro.

RESULTS

Diagnoses of depression, other anxiety disorders, and alcohol-related disorder were more prevalent in the people with PTSD than in those without PTSD. Using the DSM-IV criteria, approximately 67% of cases presenting PTSD were also diagnosed with another mental disorder. The diagnosis category of other anxiety disorders presented the highest proportion of comorbidity (53%). Depression was found in 34% person with PTSD whilst alcohol-related disorders were observed in 7%. Considering the temporal relationship, the onset of comorbid depression was uniformly distributed through the periods before, within the same year and after PTSD's onset. When other anxiety disorders were comorbid with PTSD, in almost 90% of the cases the other anxiety disorders preceded PTSD. For comorbidity between of alcohol-related disorders and PTSD, in 50% of the cases alcohol-related disorders preceded the diagnosis of PTSD.

LIMITATIONS

The cross-sectional design imposes limitations on establishing a temporal relationship between the onset of psychiatric disorders due to memory bias.

CONCLUSIONS

Our findings indicate that among individuals presenting comorbid PTSD and other anxiety disorders, this diagnosis tend to precede PTSD. Comorbid cases are more frequent and more severe, and this should be taken into account in therapeutic research and clinical practice.

Implementation and evaluation of depression screening in patients with recently diagnosed coronary artery disease

Introduction

Patients with coronary artery disease (CAD) are at an increased risk for depression. Additionally, comorbid depression in patients with CAD is associated with increased mortality and worse cardiac outcomes. Screening this patient population for depression is recommended but is not routinely done in practice. The purpose of this quality improvement initiative was to implement a protocol to screen patients with CAD for depression using the Patient Health Questionnaire (PHQ-9). Primary objectives were to determine the frequency of positive depression screens and the frequency of acceptance of mental health (MH) service referral.

Methods

Patients with CAD were screened for depression using the PHQ-9 during a hospital admission to the inpatient cardiology unit at the Clement J. Zablocki Veterans Affairs Medical Center. All patients were rescreened for depression at 4 and 8 weeks after discharge. Patients with positive screens for depression were offered referral for MH services, and reasons for decline were documented.

Results

Of the 36 patients screened for depression, 14 (39%) screened positive for depression, including 10 patients at baseline (28%), 3 additional patients (8%) at week 4 after discharge, and 1 additional patient (3%) at week 8 after discharge. Of the 14 patients who screened positive for depression, 3 patients (21%) accepted MH service referral. The most commonly reported reason for declining referral was no perceived benefit.

Discussion

The results of this initiative support the utility of using the PHQ-9 for depression screening in patients with recently diagnosed CAD and offering MH service referral for treatment of comorbid depression.

The Association of Childhood Experience of Peer Bullying with DSM-IV Psychiatric Disorders and Suicidality in Adults: Results from a Nationwide Survey in Korea

BACKGROUND

Few studies have examined the association between childhood bullying and adulthood mental disorders based on the Diagnostic and Statistical Manual of Mental Disorders (DSM) criteria. We investigated the association of childhood peer bullying with Diagnostic and Statistical Manual of Mental Disorders, fourth edition (DSM-IV) psychiatric disorders and suicidality in adults.

METHODS

A total of 5,102 respondents aged 18 or over completed the Korean version of the Composite International Diagnostic Interview for DSM-IV psychiatric disorders and a questionnaire for suicidal ideas, plans, and attempts. We evaluated peer bullying using an item in the Adverse Childhood Experiences International Questionnaire. Logistic regression analyses were used to identify the association between victimization of peer bullying, adult psychiatric disorders, and suicidality.

RESULTS

Around 8.8% of the general population in Korea reported the experience of being bullied when growing up. Bullying experience was associated with an increase in the adulthood prevalence of nicotine use disorders (adjusted odds ratio [aOR], 2.47; 95% confidence interval [CI], 1.75-3.49), alcohol use disorders (aOR, 1.93; 95% CI, 1.49-2.51), mood disorders (aOR, 4.23; 95% CI, 3.01-5.94), and anxiety disorders (aOR, 2.89; 95% CI, 1.89-4.43) after adjusting for sociodemographic variables. Among anxiety disorders, the OR for post-traumatic stress disorder (aOR, 9.95; 95% CI, 5.62-17.63) was notably high. Frequent victimization (many times) was significantly associated with suicidality even after adjusting for sociodemographic variables and lifetime prevalence of psychiatric disorders, whereas occasional victimization (once or a few times) was not.

CONCLUSION

Childhood bullying experience was associated with adult psychiatric disorders and suicidality. The findings indicated the importance of the early detection and management of childhood peer bullying to reduce detrimental adulthood consequences.

Four Decades after War: Incident Diabetes among Women Vietnam-Era Veterans in the HealthViEWS Study

OBJECTIVES

We analyzed long-term differences in incident diabetes associated with military service in a warzone among women who served during the Vietnam War era.

METHODS

For HealthViEWS, the largest later-life study of women Vietnam War-era U.S. veterans, a population-based retrospective cohort who served during 1965-1973 completed a health interview in 2011-2012. This cohort included women deployed to Vietnam, near Vietnam, or who served primarily in the United States. We hypothesized a warzone exposure gradient: Vietnam (highest exposure), near Vietnam, and the United States (lowest exposure). We used an extended Cox regression to test for differences in incident diabetes by location of wartime service.

RESULTS

Of 4,503 women in the analysis, 17.7% developed diabetes. Adjusting for demographics and military service characteristics, hazard of incident diabetes was significantly lower initially in the Vietnam group compared with the U.S. group (hazard ratio, 0.33; 95% confidence interval, 0.15-0.69). However, lower diabetes hazard in the Vietnam group was not constant over time; rather, hazard accumulated faster over time in the Vietnam group compared with the U.S. group (hazard ratio, 1.38; 95% confidence interval, 1.11-1.72). No significant difference in diabetes hazard was found between the near Vietnam and U.S. groups. Older age during military service, minority race/ethnicity, and lower military rank were associated with a higher diabetes hazard.

CONCLUSIONS

Women deployed to a warzone might have protective health factors that lower risk for diabetes early in their military career, but delivery systems for long-term health should consider that a lower risk for chronic diseases like diabetes can wane quickly in the decades that follow warzone service.

Accuracy of Anxiety Disorder Not Otherwise Specified Diagnosis in Older Veterans

We examined the accuracy of the anxiety not otherwise specified (anxiety NOS) diagnosis in 61 patients, using data from older Veterans screened for a large trial of cognitive behavioral therapy for late-life generalized anxiety disorder. We compared the anxiety NOS diagnoses based on the electronic medical record to diagnoses obtained via a gold standard structured diagnostic interview conducted for this trial. We found concordance of the anxiety NOS diagnosis in only 2 participants (3%). Most patients (77%) met diagnostic criteria for a specific Diagnostic & Statistical Manual of Mental Disorders, Fourth Edition (DSM-IV) anxiety disorder, including generalized anxiety disorder, posttraumatic stress disorder, panic disorder, and/or social anxiety disorder, on the basis of a structured diagnostic interview. The erroneous diagnosis of anxiety NOS is a barrier to patients receiving appropriate evidence-based care for specific anxiety-related and trauma-related disorders. Undertreated anxiety can result in poorer health outcomes, overutilization of medical services, and increased health care costs. Accurate diagnosis of anxiety disorders is foundational to evidence-based treatment; thus, it is imperative that patients presenting with anxiety symptoms receive proper diagnostic assessment to facilitate access to the appropriate evidence-based mental health services.

Ten-Year Prevalence of Cognitive Impairment Diagnoses and Associated Medical and Psychiatric Conditions in a National Cohort of Older Female Veterans

OBJECTIVE

Veterans are at risk for dementia because of elevated general risk factors and exposure to military risk factors; however, few studies have focused on female veterans despite their growing numbers. We sought to characterize the 10-year prevalence of cognitive impairment (i.e., mild cognitive impairment and dementia) and associated conditions in older female veterans.

METHODS

Data were extracted from Veterans Health Administration medical records of 168,111 female veterans aged 65 and older. Cognitive impairment (CI) diagnoses were defined using International Classification of Diseases, Ninth Revision (ICD-9) codes or dementia medication prescriptions. Medical comorbidities and psychiatric conditions were determined using ICD-9 codes occurring within 2years of CI diagnosis or the last recorded medical encounter for veterans without CI.

RESULTS

Ten-year prevalence was 1.8% (3,075) for mild cognitive impairment (MCI) diagnoses and 8.1% (13,653) for dementia diagnoses. Prevalence increased with age (MCI age 65: 1.4%; age 85+: 2.7%; dementia age 65: 2.5%; age 85+: 17.7%); 37.3% had dementia subtype diagnoses, with Alzheimer's disease being the most prevalent (72.7%). 47.7% of veterans with CI had at least one medical comorbidity, whereas 22.5% had at least one psychiatric condition.

CONCLUSION

Few studies have characterized the prevalence of cognitive impairment in female veterans despite the expected increases in CI and impending demographic shifts in the military. The high prevalence of medical and psychiatric conditions in female veterans with CI highlights their healthcare burden and emphasizes the need for further investigations into the prevention, treatment, and care of cognitive impairment in this understudied population.

Psychiatric Care of the Post-September 11 Combat Veteran: A Review

BACKGROUND

Post-September 11, 2001 combat veterans represent a growing cohort of patients with unique mental health needs, particularly around post-traumatic stress disorder (PTSD) and traumatic brain injury (TBI). The United States (US) remains engaged in conflicts around the globe, so this patient cohort will continue to grow in number. With around 40% of American combat veterans from Iraq and Afghanistan seeking mental health care outside of the Veterans Affairs, understanding the psychiatric needs of the post-September 11 combat veteran is an important goal for all psychiatrists. These patients are relevant to consultation-liaison (C-L) psychiatrists because of their high comorbidity of conditions such as TBI, obstructive sleep apnea, insomnia, and chronic pain. This article reviews the current literature on mental health care for the post-September 11 combat veteran, emphasizing PTSD and TBI treatment, and culling evidence-based recommendations from randomized controlled trials of combat veterans. Emphasis is also placed on the Veterans Affairs/Department of Defense Clinical Practice Guidelines. The authors also bring unique clinical expertise of having served on active duty as psychiatrists for the US Army, including in a combat zone, and both currently work in a Veterans Affairs Iraq and Afghanistan combat veteran mental health clinic.

OBJECTIVE

This review outlines useful treatment approaches for PTSD and TBI and briefly covers the comorbid conditions of major depression, chronic pain, and substance use disorders. This review will prepare C-L psychiatrists to care for this challenging patient cohort.

Obsessive-Compulsive Tendencies in a Sample of Veterans With Posttraumatic Stress Disorder

Obsessive-compulsive disorder (OCD) is considered one of the most debilitating disorders worldwide. Data suggests that trauma may be a significant source of not only posttraumatic stress disorder (PTSD), but also OCD. An epidemiologic study of the general population found the risk for OCD to be increased 10-fold in persons with PTSD. The National Vietnam Veterans Readjustment Study found the prevalence of OCD to be 5.2% in war-zone veterans and other studies highlighted PTSD-OCD comorbidity rates ranging from 41% to 70%. However, the frequency of diagnosed OCD is low among veterans (0.6%), and veterans with OCD receive little mental healthcare after diagnosis (mean: 3.8 sessions). The present study examined obsessive-compulsive (OC) tendencies in a sample of veterans with PTSD seeking treatment in a Veterans Affairs (VA) PTSD program between 2011 and 2013. Of the 318 veterans with PTSD included in the current study, 125 (36%) also reported OC tendencies. Data analyses revealed that participants with PTSD who showed evidence of OC tendencies demonstrated more severe PTSD symptoms, higher anxiety sensitivity, and lower cognitive flexibility than participants with PTSD without comorbid OC tendencies; no differences regarding posttraumatic growth were found between the two groups. This is a preliminary study aiming to assess OC tendencies in a sample of veterans with PTSD and expand on the limited existing literature on OCD-PTSD comorbid presentation among veterans.

Prevalence and Treatment of Obsessive-Compulsive Disorder in Veterans and Active-Duty Service Members: A Systematic Review

The prevalence and treatment of obsessive-compulsive disorder (OCD) in veterans and active-duty military remains unclear. We systematically reviewed literature on OCD diagnosis and treatment in U.S. Veterans and active-duty military to obtain a prevalence estimate, describe treatment approaches for OCD in veterans, and evaluate use of Exposure and Response Prevention (ERP). Eight terms were used to identify studies in PubMed, PsychINFO and SCOPUS up to March 13, 2018; additional articles were identified from reference lists of 19 included studies, 16 addressing prevalence, and 3 addressing treatment. OCD prevalence is lower in studies employing electronic medical records databases than in studies using OCD assessments, suggesting underrecognition of OCD in clinical settings. Higher prevalence was seen with OCD screening tools than with diagnostic interviews. Lower OCD prevalence was seen in active-duty individuals than in veterans. Two case studies showed a decrease in OCD symptoms following ERP. Additional studies with larger samples and controlled designs examining ERP are needed.

Military-related risk factors in female veterans and risk of dementia

OBJECTIVE

To determine whether diagnoses of traumatic brain injury (TBI), posttraumatic stress disorder (PTSD), and depression, alone or in combination, increase dementia risk among older female veterans.

METHODS

This cohort study included data from 109,140 female veterans ≥55 years of age receiving care from Veterans Health Administration medical centers in the United States between October 2004 and September 2015 with at least 1 follow-up visit. TBI, PTSD, depression, and medical conditions at study baseline and incident dementia were determined according to ICD-9-CM codes. Fine-Gray proportional hazards models were used to determine the association between military-related risk factors and dementia diagnosis, accounting for the competing risk of death.

RESULTS

During follow-up (mean 4.0 years, SD 2.3), 4% of female veterans (n = 4,125) developed dementia. After adjustment for demographics and medical conditions, women with TBI, PTSD, and depression had a significant increase in risk of developing dementia compared to women without these diagnoses (TBI-adjusted subdistribution hazard ratio [adjusted sHR] 1.49, 95% confidence interval [CI] 1.01-2.20; PTSD adjusted sHR 1.78, 95% CI 1.34-2.36; and depression-adjusted sHR 1.67, 95% CI 1.55-1.80), while women with >1 diagnosis had the highest risk for dementia (adjusted sHR 2.15, 95% CI 1.84-2.51).

CONCLUSIONS

We found that women with military-related risk factors had an ≈50% to 80% increase in developing dementia relative to women without these diagnoses, while female veterans with multiple risk factors had a >2-fold risk of developing dementia. These findings highlight the need for increased screening of TBI, PTSD, and depression in older women, especially female veterans.

Sleep Disturbance, Diabetes, and Cardiovascular Disease in Postmenopausal Veteran Women

PURPOSE OF THE STUDY

To compare the prevalence and cardiometabolic health impact of sleep disturbance among postmenopausal Veteran and non-Veteran participants in the Women's Health Initiative (WHI).

DESIGN AND METHODS

The prevalence of five categories of sleep disturbance--medication/alcohol use for sleep; risk for insomnia; risk for sleep disordered breathing [SDB]; risk for comorbid insomnia and SDB (insomnia + SDB); and aberrant sleep duration [SLD]--was compared in 3,707 Veterans and 141,354 non-Veterans using logistic or multinomial regression. Cox proportional hazards models were used to evaluate the association of sleep disturbance and incident cardiovascular disease (CVD) and Type 2 diabetes in Veterans and non-Veterans.

RESULTS

Women Veterans were more likely to have high risk for insomnia + SDB relative to non-Veteran participants. However, prevalence of other forms of sleep disturbance was similar across groups. Baseline sleep disturbance was not differentially associated with cardiometabolic health outcomes in Veteran versus non-Veteran women. Risks for SDB and insomnia + SDB were both linked to heightened risk of CVD and diabetes; SLD was consistently linked with greater risk of CVD and diabetes in non-Veterans but less strongly and consistently in Veterans.

IMPLICATIONS

Efforts to identify and treat sleep disturbances in postmenopausal women are needed and may positively contribute to the attenuation of cardiometabolic morbidity risk. Increased awareness of women Veterans' vulnerability to postmenopausal insomnia + SDB may be particularly important for health care providers who treat this population.

The effect of military deployment on mental health

Public concern about soldiers' mental health has increased over the last decade. Yet the large literature on the mental health problems of returning soldiers relies primarily on self-reported measures that may suffer from non-response bias, usually refers to older conflicts, and focuses mainly on specific diagnoses such as PTSD. Another challenge is that the differences between soldiers and non-soldiers are not necessarily causal, instead possibly reflecting an underlying propensity towards active military service. Using the objective measures of hospitalizations and the purchase of mental health medication, this paper is the first to investigate the effect of recent military deployments on a broader measure of mental health, for a full population of Danish soldiers and a comparison group of eligible men. We exploit a panel of Danish health administrative records and use propensity score matching process, using unique observables such as ability tests. Matching is helpful in both reducing the selection bias from observables and determining pre- and post-deployment period for the comparison group. Then, we estimate the effect of deployment in a difference-in-differences setting, controlling for time trends and other omitted variables affecting both groups. Overall, we find a significant and long-lasting adverse effect of military deployment on soldiers' mental health, regardless of the comparison groups and underlying assumptions.

The Relevance of Bionian Thinking to the Treatment of PTSD Patients

Analysts who conduct trauma-focused treatments have much to learn from Wilfred Bion's contributions to the understanding and treatment of PTSD. Concepts such as catastrophe and catastrophic change can illuminate the subjective experience of PTSD patients, the beta screen concept sheds light on dissociative phenomena, and, as shown in a clinical vignette, the analyst can use his alpha function to transform the patient's fragmented raw material into alpha elements. A second clinical vignette shows how during a cognitive intervention the analyst can impart this alpha function to the patient and use his reverie to help the patient assimilate previously intolerable fragments into a coherent narrative. Finally, the idea of knowing mental pain (Bion's K) is discussed in relation to the processing of traumatic memories.

Relationship of War-Zone Coping Strategies to Long-Term General Life Adjustment Among Vietnam Veterans: Combat Exposure as a Moderator Variable

In this study, we examined long-term general life adjustment among members of one trauma-exposed population, Vietnam veterans, using data from a nationally representative sample. Our particular concern was the relationship between coping strategies used in the war zone and the outcomes of achievement, life satisfaction, and lifetime adaptation (the latter defined in terms of the absence of psychosocial problems in core life domains) as a function of level of combat exposure. Hierarchical multiple regression analyses supported a hypothesized quadratic interaction between problem-focused coping and the outcomes of achievement and lifetime adaptation, with this form of coping most strongly related to adjustment (positively) at moderate levels of combat exposure. One aspect of emotion-focused coping, the use of wishful thinking, likewise interacted in a quadratic manner for the dependent variable of achievement, exhibiting its strongest association with adjustment (negatively) at moderate levels of combat exposure. The importance of interactions between coping and stressors, especially quadratic interactions, is emphasized.

Can social policy influence socioeconomic disparities? Korean War GI Bill eligibility and markers of depression

PURPOSE

The Korean War GI Bill provided socioeconomic benefits to veterans; however, its association with health is unclear; we hypothesize GI Bill eligibility is associated with fewer depressive symptoms and smaller disparities.

METHODS

Data from 246 Korean War GI Bill eligible veterans and 240 nonveterans from the Health and Retirement Study were matched on birth year, southern birth, race, height, and childhood health using coarsened exact matching. Number of depressive symptoms in 2010 (average age = 78 years) was assessed using a modified, validated Center for Epidemiologic Studies-Depression Scale, dichotomized to reflect elevated depressive symptoms. Regression analyses were stratified into low (at least one parent < 8 years schooling/missing data, n = 167) or high (both parents ≥ 8 years schooling, n = 319) childhood socioeconomic status (cSES) groups.

RESULTS

Korean War GI Bill eligibility predicted fewer depressive symptoms among individuals from low cSES backgrounds [β = -0.64, 95% confidence interval (CI) = (-1.18, -0.09), P = .022]. Socioeconomic disparities were smaller among veterans than nonveterans for number of depressive symptoms [β = -0.76, 95% CI = (-1.33, -0.18), P = .010] and elevated depressive symptoms [β = -11.7, 95% CI = (-8.2, -22.6), P = .035].

CONCLUSIONS

Korean War GI Bill eligibility predicted smaller socioeconomic disparities in depression markers.

Depression and anxiety symptoms in male veterans and non-veterans: the Health and Retirement Study

OBJECTIVES

We examined whether veteran status was associated with elevated depression and anxiety symptoms in men aged 50 and older after adjusting for sociodemographic factors.

METHODS

Participants were 6577 men aged 50 years and older who completed the 2006 wave of the Health and Retirement Study (HRS). Forty-nine percent of participants were veterans. A randomly selected subset of participants completed the HRS Psychosocial Questionnaire (N = 2957), which contained the anxiety items. Elevated depression and anxiety symptoms were determined based on brief versions of Center for Epidemiologic Studies--Depression Scale (CES-D total score ≥ 4) and Beck Anxiety Inventory (BAI total score ≥ 12).

RESULTS

Elevated depression and anxiety symptoms were found in 11.0 and 9.9% of veterans, respectively, compared with 12.8 and 12.3% of non-veterans. Veteran status was not associated with increased odds of anxiety or depression symptoms in the multivariable-adjusted logistic regression analyses. Additional analyses indicated that Vietnam War veterans were more than twice as likely as World War II or Korean War veterans to have elevated depression symptoms (OR = 2.15, 95% CI: 1.54-3.00) or anxiety symptoms (OR = 2.12, 95% CI: 1.28-3.51).

CONCLUSIONS

In a community-based sample of men aged 50 and older, veteran status was not associated with the presence of elevated depression and anxiety symptoms. Rather, these symptoms were associated with age, ethnicity, education, and medical conditions. Among veterans, cohort effects accounted for differences in psychiatric symptoms. Including younger cohorts from the Global War on Terror may yield different results in future studies.

Correlates of major depressive disorder with and without comorbid alcohol use disorder nationally in the veterans health administration

BACKGROUND AND OBJECTIVES

This study assesses medical and psychiatric comorbidities, service utilization, and psychotropic medication prescriptions in veterans with comorbid major depressive disorder (MDD) and alcohol use disorder (AUD) relative to veterans with MDD alone.

METHODS

Using cross-sectional administrative data (fiscal year [FY]2012: October 1, 2011-September 30, 2012) from the Veterans Health Administration (VHA), we identified veterans with a diagnosis of current (12-month) MDD nationally (N = 309,374), 18.8% of whom were also diagnosed with current (12-month) AUD. Veterans with both MDD and AUD were compared to those with MDD alone on sociodemographic characteristics, current (12-month) medical and psychiatric disorders, service utilization, and psychotropic prescriptions. We then used logistic regression analyses to calculate odds ratio and 95% confidence interval of characteristics that were independently different between the groups.

RESULTS

Dually diagnosed veterans with MDD and AUD, relative to veterans with MDD alone, had a greater number of comorbid health conditions, such as liver disease, drug use disorders, and bipolar disorder as well as greater likelihood of homelessness and higher service utilization.

CONCLUSIONS AND SCIENTIFIC SIGNIFICANCE

Dually diagnosed veterans with MDD and AUD had more frequent medical and psychiatric comorbidities and more frequently had been homeless. These data suggest the importance of assessing the presence of comorbid medical/psychiatric disorders and potential homelessness in order to provide appropriately comprehensive treatment to dually diagnosed veterans with MDD and AUD and indicate a need to develop more effective treatments for combined disorders.

Association of eating disorder symptoms with internalizing and externalizing dimensions of psychopathology among men and women

OBJECTIVE

A large body of factor analytic research supports the idea that common mental disorders are organized along correlated latent dimensions termed internalizing and externalizing. Eating disorders (EDs) have been associated with both internalizing (mood and anxiety disorders) and externalizing (substance use, antisocial personality disorder) forms of psychopathology. Previous studies found that EDs are most strongly related to internalizing disorders. However, no previous factor analytic studies of EDs and the internalizing/externalizing dimensions have evaluated if EDs align with these spectra similarly for men and women. We examined the location of anorexia nervosa (AN), bulimia nervosa (BN), and binge eating disorder (BED) symptoms within this model of psychopathology among a sample of veterans, a population traditionally understudied in EDs.

METHOD

Data were from two studies of veterans and their intimate partners (N = 453 men and 307 women). Participants were administered the Structured Clinical Interview for DSM-IV without skip-outs. Lifetime symptom severity scores were used in confirmatory factor analytic models.

RESULTS

A model with AN, BN, and BED symptoms loading onto the distress subfactor of the internalizing domain fit the data best in the full sample and the male and female subsamples. This model was statistically equivalent for men and women.

DISCUSSION

All three EDs loaded onto distress, indicating that these conditions overlap with psychopathology characterized by negative affect. Investigating latent dimensions of psychopathology is one approach to identifying common factors that partially account for patterns of comorbidity among psychiatric disorders, which may aid in translating research findings into clinical practice.

The influence of diagnosis on psychotherapy missed opportunities in a veteran population

OBJECTIVE

Canceled or unattended psychotherapy sessions are a source of concern for patients, providers, and health-care systems. Veterans are particularly likely to experience mental health problems, and yet they are also especially susceptible to variables leading to premature termination of services.

METHOD

This study examined a large (n = 2285) sample of veterans receiving psychotherapy services to determine if mental health diagnosis had an impact upon missed psychotherapy opportunities.

RESULTS

There were differential cancelation rates for individuals with different classes of disorder, and the total number of appointments a person scheduled changed the nature of the effect.

CONCLUSIONS

Health-care administrators and treatment providers should consider the specific effects of individuals with differing diagnoses when planning courses of treatment and coordinating care.

The anatomy of primary care and mental health clinician communication: a quality improvement case study

BACKGROUND

The high prevalence of comorbid physical and mental illnesses among veterans is well known. Therefore, ensuring effective communication between primary care (PC) and mental health (MH) clinicians in the Veterans Affairs (VA) health care system is essential. The VA's Patient Aligned Care Teams (PACT) initiative has further raised awareness of the need for communication between PC and MH. Improving such communication, however, has proven challenging.

OBJECTIVE

To qualitatively understand barriers to PC-MH communication in an academic community-based clinic by using continuous quality improvement (CQI) tools and then initiate a change strategy.

DESIGN, PARTICIPANTS, AND APPROACH

An interdisciplinary quality improvement (QI) work group composed of 11 on-site PC and MH providers, administrators, and researchers identified communication barriers and facilitators using fishbone diagrams and process flow maps. The work group then verified and provided context for the diagram and flow maps through medical record review (32 patients who received both PC and MH care), interviews (6 stakeholders), and reports from four previously completed focus groups. Based on these findings and a previous systematic review of interventions to improve interspecialty communication, the team initiated plans for improvement.

KEY RESULTS

Key communication barriers included lack of effective standardized communication processes, practice style differences, and inadequate PC training in MH. Clinicians often accessed advice or formal consultation based on pre-existing across-discipline personal relationships. The work group identified collocated collaborative care, joint care planning, and joint case conferences as feasible, evidence-based interventions for improving communication.

CONCLUSIONS

CQI tools enabled providers to systematically assess local communication barriers and facilitators and engaged stakeholders in developing possible solutions. A locally tailored CQI process focusing on communication helped initiate change strategies and ongoing improvement efforts.

[Emotional Profile of a Group of Colombian Military Victims of Landmines or Improvised Explosive Devices]

INTRODUCTION

Antipersonnel Mines (MAP) and Improvised Explosive Devices (IEDs) are frequently used in Colombia as an armed resource without the need for direct combat. The Department of Antioquia has the highest number of events associated with the detonation of such battle techniques. There are no studies on the psychological effects that appear as a result of accidents with Antipersonnel Mines and IEDs in the military population.

OBJECTIVE

To establish the psychological profile of a group of military victims of MAP and AEI, and a control group of soldiers who were not victims from the analysis of four emotional variables (depression, anxiety, anger and stress).

METHODS

The research was conducted using a case-control design in a .quantitative, comparative, descriptive and cross-sectional study.

PARTICIPANTS

A sample of 80 soldiers assigned to the Seventh Division of the National Army of Colombia at Medellin, Antioquia. The sample included a group of 30 military cases and 50 soldiers as controls.

RESULTS

The anxiety state, trait anxiety, state anger, and trait anger variables showed statistically significant differences between groups. There were no significant differences in the variables depression and stress between groups variables. There was no depression, anxiety, or stress in either of the two groups, but there were clinically significant levels of anger in both groups.

Diagnostic specificity and mental health service utilization among veterans with newly diagnosed anxiety disorders

OBJECTIVE

This study examined rates of specific anxiety diagnoses (posttraumatic stress disorder, generalized anxiety disorder, panic disorder, obsessive-compulsive disorder, social anxiety disorder, and specific phobia) and anxiety disorder not otherwise specified (anxiety NOS) in a national sample of Veterans and assessed their mental health service utilization.

METHOD

This study used administrative data extracted from Veteran Health Administration outpatient records to identify patients with a new anxiety diagnosis in fiscal year 2010 (N = 292,244). Logistic regression analyses examined associations among diagnostic specificity, diagnostic location, and mental health service utilization.

RESULTS

Anxiety NOS was diagnosed in 38% of the sample. Patients in specialty mental health were less likely to receive an anxiety NOS diagnosis than patients in primary care (odds ratio [OR] = 0.36). Patients with a specific anxiety diagnosis were more likely to receive mental health services than those with anxiety NOS (OR = 1.65), as were patients diagnosed in specialty mental health compared with those diagnosed in primary care (OR = 16.29).

CONCLUSION

Veterans diagnosed with anxiety NOS are less likely to access mental health services than those with a specific anxiety diagnosis, suggesting the need for enhanced diagnostic and referral practices, particularly in primary care settings.

Increased risk of alcohol dependency in a cohort of National Guard troops with PTSD: a longitudinal study

Studies show high rates of co-morbid post-traumatic stress disorder (PTSD) and alcohol use disorder (AUD) but there is no consensus on the causal direction of the relationship. Some theories suggest AUD develops as a coping mechanism to manage PTSD symptoms and others that AUD is a vulnerability factor for PTSD. A third hypothesis posits independent developmental pathways stemming from a shared etiology, such as the trauma exposure itself. We examined these hypotheses using longitudinal data on 922 National Guard soldiers, representing a subsample (56%) of a larger pre- and post-deployment cross-sectional study of New Jersey National Guard soldiers deployed to Iraq. Measures included the PTSD Checklist (PCL), DSM-IV-based measures of alcohol use/misuse from the National Household Survey of Drug Use and Health and other concurrent mental health, military and demographic measures. Results showed no effect of pre-deployment alcohol status on subsequent positive screens for new onset PTSD. However, in multivariate models, baseline PTSD symptoms significantly increased the risk of screening positive for new onset alcohol dependence (AD), which rose 5% with each unit increase in PCL score (AOR = 1.05; 95% CI = 1.02-1.07). Results also supported the shared etiology hypothesis, with the risk of a positive screen for AD increasing by 9% for every unit increase in combat exposure after controlling for baseline PTSD status (AOR = 1.09; 95% CI = 1.03-1.15) and, in a subsample with PCL scores <34, by 17% for each unit increase in exposure (AOR = 1.17; 95% CI = 1.05-1.31). These findings have implications for prevention, treatment and compensation policies governing co-morbidity in military veterans.
