Longitudinal association of health behaviors and health-related quality of life with military spouse readiness.

BACKGROUND: Unhealthy behaviors impose costs on health-related quality of life (HRQOL) reducing productivity and readiness among military members (Hoge et al., JAMA 295:1023-32, 2006; Mansfield et al. 362:101-9, 2010). Among married personnel in particular, patterns of spouse health behaviors may play an interdependent role. As a result, the identification of military spouse health factors related to readiness may inform strategies to screen for and identify those in need of greater support and enhance readiness. This study explored behavioral and HRQOL predictors and potential mediators of military spouse readiness utilizing data from the Millennium Cohort Family Study. METHODS: The analytic sample comprised of 3257 spouses of active-duty, non-separated service members who responded to both waves 1 and 2 of the survey. Sample characteristics are described with respect to demographics (e.g., age, sex, race/ethnicity, etc.), readiness measures (i.e., military satisfaction, lost workdays, health care utilization, military-related stress, and satisfaction), health behaviors (i.e., exercise, sleep, smoking, and alcohol use) and HRQOL (Veterans RAND 12-Item Short Form Survey). We conducted multivariate mediation analyses to evaluate the role of mental and physical HRQOL as mediators between the baseline health behaviors and the health readiness outcomes at follow-up, while adjusting for spouse and service member demographics. RESULTS: HRQOL had direct effects for all five readiness outcomes examined. Multiple health behaviors (insomnia, smoking, binge drinking, and exercise) were further significantly associated with spouse readiness outcomes, although most effects were mediated through HRQOL, suggesting this may be a useful index of military spouse readiness. Insomnia was the specific health behavior most consistently associated with poorer readiness across outcomes, and effects were only partially mediated by physical and mental HRQOL. CONCLUSIONS: The results show spouse health behaviors are directly and indirectly (through HRQOL) associated with readiness indicators. This suggests that assessments of modifiable health behaviors (e.g., insomnia symptoms) and mental and physical HRQOL are important indicators of readiness among military spouses and should be used to inform future programs designed to improve population health.

Partner Effects: Analyzing Service Member and Spouse Drinking Over Time.

INTRODUCTION: Excessive alcohol use is a significant problem in the military. Although there is a growing emphasis on family-centered alcohol prevention approaches, little is known about the interplay between partners' drinking behaviors. This study examines how service members and their spouses influence each other's drinking behavior over time and explores the complex individual, interpersonal, and organizational factors that may contribute to alcohol use. METHODS: A sample of 3,200 couples from the Millennium Cohort Family Study was surveyed at baseline (2011-2013) and follow-up (2014-2016). The research team estimated how much partners' drinking behaviors influenced one another from baseline to follow-up using a longitudinal structural equation modeling approach. Data analyses were conducted in 2021 and 2022. RESULTS: Drinking patterns converged between spouses from baseline to follow-up. Participants' own baseline drinking had a small but significant effect on changes in their partners' drinking from baseline to follow-up. Results from a Monte Carlo simulation showed that the longitudinal model could reliably estimate this partner effect in the presence of several potential sources of bias, including partner selection. The model also identified several common risk and protective factors for drinking shared by both service members and their spouses. CONCLUSIONS: Findings suggest that changing the drinking habits of one spouse could lead to a change in the drinking habits of the other, which supports family-centered alcohol prevention approaches in the military. Dual-military couples especially may benefit from targeted interventions because they face a higher risk of unhealthy alcohol consumption.

Longitudinal Patterns of Military Spousal Alcohol Consumption: Findings From the Millennium Cohort Family Study.

OBJECTIVE: Alcohol use in the military is prevalent and has short- and long-term health, safety, and career consequences. Although several studies have examined service members' alcohol consumption, few have focused on alcohol use among military spouses. This study assessed factors at individual, interpersonal, and organizational levels to determine associations with risky alcohol use among military spouses. METHOD: Data from baseline and first follow-up of the Millennium Cohort Family Study were used (N = 5,475; 4,923 female) to model spousal self-reported risky drinking (heavy and/or binge drinking) at follow-up. Predictors included demographic characteristics, spousal adverse childhood experiences and mental health, smoking status, marital status, family satisfaction, social support, military stress, and service member military characteristics. Logistic regression models assessed the adjusted associations between spouse and service member characteristics and spousal risky drinking at follow-up. RESULTS: Among spouses in this sample, 19% were risky drinkers at follow-up. Baseline alcohol use status was associated with risky drinking at follow-up. Most spouses (64.2%) did not change their drinking behavior between baseline and follow-up; those who did change were nearly evenly split between an increasing (17.0%) versus decreasing (18.7%) pattern. Risk factors included male gender, cigarette smoking, elevated symptoms of post-traumatic stress, marital separation, and service member deployment with combat. CONCLUSIONS: Although most military spouses were not engaging in risky drinking, one in five were, with about half of these having moved into the risky drinking category over time. Risky alcohol use among spouses has ramifications for themselves, the service member, and the family unit.

Families serve too: military spouse well-being after separation from active-duty service.

BACKGROUND AND OBJECTIVES: Transitioning from military to civilian life can be challenging for families, but most research focuses only on the service member. We applied a life course model to assess spouse well-being following this important transition. DESIGN: Prospective, longitudinal survey of service members and their spouses. METHODS: We captured three spouse well-being domains: psychological health, physical health, and family relationships. We identified differences between families who separated from service and those still affiliated (N = 4,087) and assessed baseline factors associated with spouse well-being after the family separated from service (N = 1,199). RESULTS: Spouses of service members who had separated from the military (versus those who had not) reported poorer mental health and family relationship quality at baseline and follow-up. After controlling for baseline differences, spouses whose families transitioned experienced a greater increase in PTSD symptoms and a steeper decline in quality of marriage. Spouses of active-duty service members reported greater increases in work-family conflict. Among families who had transitioned, the most consistent predictor of positive outcomes was baseline well-being. Protective factors included having more psychological and social resources and less financial stress. CONCLUSIONS: Several protective and risk factors identified in the study may inform programming for families transitioning from active duty.

Associations between spouse and service member prescriptions for high-risk and long-term opioids: A dyadic study.

BACKGROUND: Estimates suggest approximately 2.4% of service members, and 15% of service members who have engaged in recent combat, report misusing pain relievers in the past year. This study explores the extent to which military spouses' obtainment of opioids is associated with their service member partners' obtainment of opioid prescriptions, in addition to other factors such as service member health, state prescribing patterns, and sociodemographic characteristics. METHODS: Data were drawn from the Millennium Cohort Family Study, a large, longitudinal survey of married spouses of service members from all service branches, and archival data analyzed from 2018 to 2020. The dependent variables were spouse long-term opioid therapy and spouse opioid prescriptions that pose a high risk of adverse outcomes. RESULTS: Seven percent of spouse and service member dyads met the criteria for high-risk opioid use, generally because they had purchased a prescription for a ≥90 Morphine Milligram Equivalents daily dose (76.7% for spouses, 72.8% for service members). Strong associations were found between spouse and service member opioid therapies (OR = 5.53 for long-term; OR = 2.20 for high-risk). CONCLUSIONS: Findings suggest that reducing the number of long-term and high-risk opioid prescriptions to service members may subsequently reduce the number of similar prescriptions obtained by their spouses. Reducing the number of service members and spouses at risk for adverse events may prove to be effective in stemming the opioid epidemic and improve the overall health and safety of military spouses and thus, the readiness of the U.S. Armed Forces.

Addressing Posttraumatic Stress Disorder in Primary Care: Primary Care Physicians' Knowledge, Confidence and Screening Practices Related to PTSD Among Military Populations.

BACKGROUND: Posttraumatic stress disorder (PTSD) is an undertreated psychological condition prevalent among service members and veterans. Members of the military community often raise mental health concerns in primary care settings. However, many primary care physicians (PCPs) lack training in PTSD within the military community and may be underprepared to discuss PTSD or trauma with patients. OBJECTIVES: We assessed PCPs' knowledge of evidence-based PTSD screening and treatment practices, confidence in their abilities to provide clinical care around PTSD, and frequency of asking new patients about their military history. We also examined PCP characteristics related to these measures. RESEARCH DESIGN: We surveyed a national sample of 7426 PCPs to assess their PTSD knowledge, confidence, and military history screening practices. Data were analyzed using weighted multivariable regressions. RESULTS: Forty-three percent of PCPs reported they very often or always screened for military history and, on average, PCPs answered 41% of the PTSD knowledge items correctly. PCPs who rated their PTSD knowledge higher were more confident and more frequently screened for military history, but did not have higher knowledge scores compared with PCPs with lower self-assessed knowledge. Several PCP characteristics, such as sex, years of practice, and practice setting, predicted PTSD measures. CONCLUSIONS: PCPs have gaps in their knowledge and screening practices related to PTSD. The absence of a meaningful correlation of knowledge scores with PCP self-assessed knowledge or confidence suggests PCPs may not accurately rate their own knowledge. Targeted, evidence-based training on effective practices may promote PTSD clinical knowledge.

Demographic Variation in Military Life Stress and Perceived Support Among Military Spouses.

INTRODUCTION: Military spouses play a critical role in supporting military service members, and thus, their experiences may have a significant impact on the well-being, readiness, and resilience of the U.S. Armed Forces. Research suggests that military spouses experience unique stressors as a result of military life, but few studies have assessed demographic factors associated with their experiences of military life and perceived support. MATERIALS AND METHODS: Using data from the Millennium Cohort Family Study, a nationwide survey of 9,872 married spouses of service members with 2 to 5 years of military service, this study examined differences in experiences of military life and perceived support across multiple understudied subgroups of military spouses. Key outcomes included military-related stressors (e.g., deployment-related experiences), perceived social support, and perceived military efforts to provide support. RESULTS: Military life stress and perceived support differed across military spouse, service member, and family characteristics. Results indicated that spouses who are older than age 35 or are married to enlisted service members in the Army, Navy, or Marines are more likely to experience heightened military stress or less perceived social support. Dual-military couples reported experiencing less stress associated with military life and perceiving more social support and support from the military, compared with spouses who have never served in the military. CONCLUSION: These findings may help guide effective channeling of resources and outreach to potentially vulnerable military families.

High-risk and Long-term Opioid Prescribing to Military Spouses in the Millennium Cohort Family Study.

INTRODUCTION: The use and misuse of opioids by active service members has been examined in several studies, but little is known about their spouses' opioid use. This study estimates the number of military spouses who received high-risk or long-term opioid prescriptions between 2010 and 2014, and addresses how the Military Health System can help prevent risky prescribing in order to improve military force readiness. MATERIALS AND METHODS: This study used data from the Millennium Cohort Family Study, a nationwide survey of 9,872 spouses of service members with 2 to 5 years of military service, augmented with information from the military's Pharmacy Data Transaction Service about prescriptions for controlled drugs dispensed to these service members' spouses. Our objectives were to estimate the prevalence of opioid prescribing indicative of long-term use (≥60 day supply or at least one extended-release opioid prescription in any 3-month period) and, separately, high-risk use (daily dosage of ≥90 morphine mg equivalent or total dosage of ≥8,190 morphine mg equivalent, or prescriptions from more than three pharmacies, or concurrent prescriptions). For each of these dependent variables, we conducted bivariate analyses and multiple logistic regression models using information about spouses' physical health, sociodemographic characteristics, substance use behaviors, perceived social support, and stresses associated with military stress, among others. Informed consent, including consent to link survey responses to medical and personnel records, was obtained from all participants. The Naval Health Research Center's Institutional Review Board and the Office of Management and Budget approved the study. RESULTS: Spouses were predominantly female (86%), had not served in the military themselves (79%), and were spouses of enlisted (91%) active duty (86%) service members. Almost half (47.6%) of spouses obtained at least one opioid prescription during the 2-year observation window, and 8.5% had received opioid prescriptions that posed risk to their health. About 7% met the criteria for receipt of high-risk opioid prescriptions, 3% obtained opioids from three or more pharmacies during a 3-month period, and 4% of spouses who received any opioids received both long-term and high-risk prescriptions. Adverse childhood experiences, physical pain, and lack of social support were associated with increased odds of obtaining high-risk opioid prescriptions. CONCLUSIONS: Approximately 48% of military spouses had used Military Health System insurance to fill at least one opioid prescription during the 2-year observation period. The Department of Defense has taken measures to minimize high-risk opioid prescribing, including passing prescribing guidelines in 2017, establishing the controlled drug management analysis reporting tool, establishing a pain management education and training program, and more. These efforts should continue to expand as reducing the numbers of service members and spouses at risk for adverse events may be effective in reducing opioid misuse and improve the overall health and safety of military spouses and thus, the readiness of the U.S. Armed Forces.

Military Life Stressors, Family Communication and Satisfaction: Associations with Children's Psychosocial Outcomes.

Families experience multiple stressors as a result of military service. The purpose of this study was to examine facets of military life and family factors that may impact child psychosocial and mental health functioning. Using baseline data from the Millennium Cohort Family Study, this study examined family demographics and composition (age, number of children), military life stressors (injury, family, and deployment stressors), family communication and satisfaction as assessed by the Family Adaptability and Cohesion Evaluation Scale-IV, parental social functioning assessed via the Short Form Health Survey-36, and child mental health and behavioral functioning (parental reports of clinician-diagnosed mental health conditions such as depression) and an adapted version of the Strengths and Difficulties Questionnaire. Injury- and family-related military stressors were significant indicators of heightened risk for child mental health conditions, whereas greater levels of parental social functioning and family satisfaction were associated with lower risk of child mental health conditions. Differential associations were found in child functioning when military-related variables (e.g., service component), sociodemographic, and family composition factors (number and age of the children in the home) were examined. These findings underscore the importance of examining the "whole child" within the broader ecological and military family context to understand factors associated with children's mental and behavioral health. The results from the present study highlight the complex relationships that may be at play, which, in turn, have considerable implications for the development of policies to support children and families encountering multiple stressors related to a parent's military service.

Association of military life experiences and health indicators among military spouses.

BACKGROUND: The health and well-being of military spouses directly contribute to a robust military force by enabling the spouse to better support the active duty member's career. In order to understand the overall health and well-being of military spouses, we assessed health indicators among military spouses using the Healthy People 2020 framework and examined associations of these health indicators with military experiences and psychosocial factors. METHODS: Using data from the Millennium Cohort Family Study, a U.S. Department of Defense-sponsored survey of 9872 spouses of service members with 2-5 years of military service, we examined attainment of Healthy People 2020 goals for spouses and service members, including healthy weight, exercise, sleep, and alcohol and tobacco use. Multivariable logistic regression models assessed associations of spouse health indicators with stressful military life experiences and social support, adjusting for demographics and military descriptors. The spousal survey was administered nationwide in 2011. RESULTS: The majority of military spouses met each health goal assessed. However, less than half met the healthy weight and the strength training goals. Reporting greater perceived family support from the military was associated with better behavioral health outcomes, while having no one to turn to for support was associated with poorer outcomes. Using the Healthy People 2020 objectives as a framework for identifying key health behaviors and benchmarks, this study identified factors, including military-specific experiences, that may contribute to physical health behaviors and outcomes among military spouses. With respect to demographic characteristics, the findings are consistent with other literature that women are more likely to refrain from risky substance use and that greater education is associated with better overall health outcomes. CONCLUSIONS: Findings suggest that enhanced social and military support and tailored programming for military spouses may improve health outcomes and contribute to the well-being of military couples. Such programming could also bolster force readiness and retention.

Mental Health of Children of Deployed and Nondeployed US Military Service Members: The Millennium Cohort Family Study.

OBJECTIVE: Families experience multiple stressors as a result of military service. The purpose of this study was to investigate the associations among service member deployment experiences, family and military factors, and children's mental health using baseline data from the Millennium Cohort Family Study, a study designed to evaluate the health and mental health effects of military service on families, including children. METHOD: This study examined administrative data on deployment status (combat, noncombat, and no deployments), as well as service member- and spouse-reported data on deployment experiences and family functioning in relation to the mental health of children in the family who were aged 9 to 17 years. RESULTS: Most children were not reported to have mental health, emotional, or behavioral difficulties regardless of parental deployment status. For an important minority of children, however, parental deployments with combat, compared with those with no deployment, were associated with a parental report of attention-deficit disorder/attention-deficit hyperactivity disorder and depression as diagnosed by a clinical provider, after accounting for demographics, psychosocial context, and military factors. Children's odds of a parental report of depression were significantly higher in both the combat and the noncombat deployment groups than in the no deployment group. CONCLUSION: These findings extend our understanding of the association between parental deployments and children's mental health, with implications for services and training mental health providers serving military families.

Prevalence of psychiatric morbidity in United States military spouses: The Millennium Cohort Family Study.

BACKGROUND: Approximately half of US service members are married, equating to 1.1 million military spouses, yet the prevalence of psychiatric morbidity among military spouses remains understudied. We assessed the prevalence and correlates of eight mental health conditions in spouses of service members with 2-5 years of service. METHOD: We employed baseline data from the Millennium Cohort Family Study, a 21-year longitudinal survey following 9,872 military-affiliated married couples representing all US service branches and active duty, Reserve, and National Guard components. Couples were surveyed between 2011 and 2013, a period of high military operational activity associated with Operation Iraqi Freedom and Operation Enduring Freedom. Primary outcomes included depression, anxiety, posttraumatic stress disorder (PTSD), panic, alcohol misuse, insomnia, somatization, and binge eating, all assessed with validated self-report questionnaires. RESULTS: A total of 35.90% of military spouses met criteria for at least one psychiatric condition. The most commonly endorsed conditions were moderate-to-severe somatization symptoms (17.63%) and moderate-to-severe insomnia (15.65%). PTSD, anxiety, depression, panic, alcohol misuse, and binge eating were endorsed by 9.20%, 6.65%, 6.05%, 7.07%, 8.16%, and 5.23% of spouses, respectively. Having a partner who deployed with combat resulted in higher prevalence of anxiety, insomnia, and somatization. Spouses had lower prevalence of PTSD, alcohol misuse, and insomnia but higher rates of panic and binge eating than service members. Both members of a couple rarely endorsed having the same psychiatric problem. CONCLUSIONS: One third of junior military spouses screened positive for one or more psychiatric conditions, underscoring the need for high-quality prevention and treatment services.

Predictors of PTSD 40 years after combat: Findings from the National Vietnam Veterans longitudinal study.

BACKGROUND: Few studies have longitudinally examined predictors of posttraumatic stress disorder (PTSD) in a nationally representative sample of US veterans. We examined predictors of warzone-related PTSD over a 25-year span using data from the National Vietnam Veterans Longitudinal Study (NVVLS). METHODS: The NVVLS is a follow-up study of Vietnam theater veterans (N = 699) previously assessed in the National Vietnam Veterans Readjustment Study (NVVRS), a large national-probability study conducted in the late 1980s. We examined the ability of 22 premilitary, warzone, and postmilitary variables to predict current warzone-related PTSD symptom severity and PTSD symptom change in male theater veterans participating in the NVVLS. Data included a self-report Health Questionnaire survey and a computer-assisted telephone Health Interview Survey. Primary outcomes were self-reported PTSD symptoms assessed by the PTSD Checklist for DSM-5 (PCL 5) and Mississippi PTSD Scale (M-PTSD). RESULTS: Predictors of current PTSD symptoms most robust in hierarchical multivariable models were African-American race, lower education level, negative homecoming reception, lower current social support, and greater past-year stress. PTSD symptoms remained largely stable over time, and symptom exacerbation was predicted by African-American race, lower education level, younger age at entry into Vietnam, greater combat exposure, lower current social support, and greater past-year stressors. CONCLUSIONS: Findings confirm the robustness of a select set of risk factors for warzone-related PTSD, establishing that these factors can predict PTSD symptom severity and symptom change up to 40 years postdeployment.

Assessing and adjusting for non-response in the Millennium Cohort Family Study.

BACKGROUND: In conducting population-based surveys, it is important to thoroughly examine and adjust for potential non-response bias to improve the representativeness of the sample prior to conducting analyses of the data and reporting findings. This paper examines factors contributing to second stage survey non-response during the baseline data collection for the Millennium Cohort Family Study, a large longitudinal study of US service members and their spouses from all branches of the military. METHODS: Multivariate logistic regression analysis was used to develop a comprehensive response propensity model. RESULTS: Results showed the majority of service member sociodemographic, military, and administrative variables were significantly associated with non-response, along with various health behaviours, mental health indices, and financial and social issues. However, effects were quite small for many factors, with a few demographic and survey administrative variables accounting for the most substantial variance. CONCLUSIONS: The Millennium Cohort Family Study was impacted by a number of non-response factors that commonly affect survey research. In particular, recruitment of young, male, and minority populations, as well as junior ranking personnel, was challenging. Despite this, our results suggest the success of representative population sampling can be effectively augmented through targeted oversampling and recruitment, as well as a comprehensive survey weighting strategy.

PTSD and Use of Outpatient General Medical Services Among Veterans of the Vietnam War.

OBJECTIVE: The primary goal of this analysis was to assess whether recent use of outpatient services for general medical concerns by Vietnam veterans varies according to level of posttraumatic stress disorder (PTSD) symptomatology over time. Another goal was to determine whether PTSD symptomatology was associated with veterans' reports of discussing behavioral health issues as part of a general medical visit. METHODS: Self-reported service use data and measures of PTSD were from a nationally representative sample of 848 male and female Vietnam theater veterans (individuals who were deployed to the Vietnam theater of operations) who participated in the National Vietnam Veterans Longitudinal Study, a 25-year follow-up of a cohort of veterans originally interviewed from 1984-1988 as part of the National Vietnam Veterans Readjustment Study. Four categories of PTSD symptomatology course over 25 years were defined, and logistic regression models were used to assess their relationship with recent use of outpatient general medical services. RESULTS: Male and female theater veterans with high or increasing PTSD symptomatology over the period were more likely than those with low symptomatology to report recent VA outpatient visits. Males in the increasing and high categories were also more likely to discuss behavioral health issues at general medical visits. CONCLUSIONS: Vietnam veterans with high and increasing PTSD symptomatology over time were likely to use VA outpatient general health services. Attention to stressors of the aging process and to persistence of PTSD symptoms is important for Vietnam veterans, as is addressing PTSD with other psychiatric and medical comorbidities within the context of outpatient general medical care.

A Prospective Study of Mortality and Trauma-Related Risk Factors Among a Nationally Representative Sample of Vietnam Veterans.

Because Vietnam veterans comprise the majority of all living veterans and most are now older adults, the urgency and potential value of studying the long-term health effects of service in the Vietnam War, including effects on mortality, is increasing. The present study is the first prospective mortality assessment of a representative sample of Vietnam veterans. We used one of the longest follow-up periods to date (spanning older adulthood) and conducted one of the most comprehensive assessments of potential risk factors. Vital status and cause of death were ascertained for the 1,632 veterans who fought in the Vietnam theater (hereafter referred to as theater veterans) and for 716 Vietnam War-era veterans (hereafter referred to as era veterans) who participated in the National Vietnam Veterans Readjustment Study (1987-2011). As of April 2011, 16.0% (95% confidence interval: 13.1, 19.0) of all Vietnam veterans who were alive in the 1980s were deceased. Male theater veterans with a high probability of posttraumatic stress disorder (PTSD) were nearly 2 times more likely to have died than were those without PTSD, even after adjustment for sociodemographic and other characteristics. A high level of exposure to war zone stress was independently associated with mortality for both male and female theater veterans after adjustment for sociodemographic characteristics, PTSD, and physical comorbid conditions. Theater veterans with a high level of exposure to war zone stress and a high probability of PTSD had the greatest mortality risk (adjusted hazard ratio = 2.34, 95% confidence interval: 1.24, 4.43).

Course of Posttraumatic Stress Disorder 40 Years After the Vietnam War: Findings From the National Vietnam Veterans Longitudinal Study.

IMPORTANCE: The long-term course of readjustment problems in military personnel has not been evaluated in a nationally representative sample. The National Vietnam Veterans Longitudinal Study (NVVLS) is a congressionally mandated assessment of Vietnam veterans who underwent previous assessment in the National Vietnam Veterans Readjustment Study (NVVRS). OBJECTIVE: To determine the prevalence, course, and comorbidities of war-zone posttraumatic stress disorder (PTSD) across a 25-year interval. DESIGN, SETTING, AND PARTICIPANTS: The NVVLS survey consisted of a self-report health questionnaire (n = 1409), a computer-assisted telephone survey health interview (n = 1279), and a telephone clinical interview (n = 400) in a representative national sample of veterans who served in the Vietnam theater of operations (theater veterans) from July 3, 2012, through May 17, 2013. Of 2348 NVVRS participants, 1920 were alive at the outset of the NVVLS, and 81 died during recruitment; 1450 of the remaining 1839 (78.8%) participated in at least 1 NVVLS study phase. Data analysis was performed from May 18, 2013, through January 9, 2015, with further analyses continued through April 13, 2015. MAIN OUTCOMES AND MEASURES: Study instruments included the Mississippi Scale for Combat-Related PTSD, PTSD Checklist for DSM-IV supplemented with PTSD Checklist for DSM-5 items (PCL-5+), Clinician-Administered PTSD Scale for DSM-5 (CAPS-5), and Structured Clinical Interview for DSM-IV, Nonpatient Version. RESULTS: Among male theater veterans, we estimated a prevalence (95% CI) of 4.5% (1.7%-7.3%) based on CAPS-5 criteria for a current PTSD diagnosis; 10.8% (6.5%-15.1%) based on CAPS-5 full plus subthreshold PTSD; and 11.2% (8.3%-14.2%) based on PCL-5+ criteria for current war-zone PTSD. Among female veterans, estimates were 6.1% (1.8%-10.3%), 8.7% (3.8%-13.6%), and 6.6% (3.5%-9.6%), respectively. The PCL-5+ prevalence (95% CI) of current non-war-zone PTSD was 4.6% (2.6%-6.6%) in male and 5.1% (2.3%-8.0%) in female theater veterans. Comorbid major depression occurred in 36.7% (95% CI, 6.2%-67.2%) of veterans with current war-zone PTSD. With regard to the course of PTSD, 16.0% of theater veterans reported an increase and 7.6% reported a decrease of greater than 20 points in Mississippi Scale for Combat-Related PTSD symptoms. The prevalence (95% CI) of current PCL-5+-derived PTSD in study respondents was 1.2% (0.0%-3.0%) for male and 3.9% (0.0%-8.1%) for female Vietnam veterans. CONCLUSIONS AND RELEVANCE: Approximately 271,000 Vietnam theater veterans have current full PTSD plus subthreshold war-zone PTSD, one-third of whom have current major depressive disorder, 40 or more years after the war. These findings underscore the need for mental health services for many decades for veterans with PTSD symptoms.

Design and methods of the national Vietnam veterans longitudinal study.

The National Vietnam Veterans Longitudinal Study (NVVLS) is the second assessment of a representative cohort of US veterans who served during the Vietnam War era, either in Vietnam or elsewhere. The cohort was initially surveyed in the National Vietnam Veterans Readjustment Study (NVVRS) from 1984 to 1988 to assess the prevalence, incidence, and effects of post-traumatic stress disorder (PTSD) and other post-war problems. The NVVLS sought to re-interview the cohort to assess the long-term course of PTSD. NVVLS data collection began July 3, 2012 and ended May 17, 2013, comprising three components: a mailed health questionnaire, a telephone health survey interview, and, for a probability sample of theater Veterans, a clinical diagnostic telephone interview administered by licensed psychologists. Excluding decedents, 78.8% completed the questionnaire and/or telephone survey, and 55.0% of selected living veterans participated in the clinical interview. This report provides a description of the NVVLS design and methods. Together, the NVVRS and NVVLS constitute a nationally representative longitudinal study of Vietnam veterans, and extend the NVVRS as a critical resource for scientific and policy analyses for Vietnam veterans, with policy relevance for Iraq and Afghanistan veterans.

Measuring coping behavior in patients with major burn injuries: a psychometric evaluation of the BCOPE.

Burn injuries involve significant physiological, psychological, and social challenges with which individuals must cope. Although the brief COPE (BCOPE) is frequently used, knowledge of its factor structure and construct validity is limited, thus limiting confidence with interpreting results. This study assessed psychometric properties of the BCOPE in hospitalized patients with burn injury. Participants had a major burn injury (n = 362). Measures assessed coping behavior and physical, psychological, and social functioning. Exploratory factorial analysis was conducted to evaluate patterns of coping strategies. To assess construct validity, the BCOPE scale scores were correlated with the distress measures across time points. Exploratory factorial analysis revealed seven factors accounting for 51% of total variance. The pattern matrix indicated four items loaded onto factor 1 (active coping = 0.47-0.80) and four onto factor 2 (avoidant coping = 0.59-0.73). The remaining factors were consistent with original scale assignments reported by Carver (Int J Behav Med 1997;4:92-100). Construct validity of BCOPE scales (active and avoidant) was demonstrated by their association with the Davidson trauma scale, short form-12, and satisfaction with appearance scale. The results indicate that the BCOPE is valid, reliable, and can be meaningfully interpreted. Research using these factors may improve knowledge about interrelationships among stress, coping, and outcome, thus building the evidence base for managing distress in this population.

Peritraumatic heart rate and posttraumatic stress disorder in patients with severe burns.

OBJECTIVE: Previous studies have suggested a link between heart rate (HR) following trauma and the development of posttraumatic stress disorder (PTSD). This study expands on previous work by evaluating HR in burn patients followed longitudinally for symptoms of acute stress disorder (ASD) and PTSD. METHOD: Data were collected from consecutive patients admitted to the Johns Hopkins Burn Center, Baltimore, Maryland, between 1997 and 2002. Patients completed the Stanford Acute Stress Reaction Questionnaire (n = 157) to assess symptoms of ASD. The Davidson Trauma Scale was completed at 1 (n = 145), 6 (n = 106), 12 (n = 94), and 24 (n = 66) months postdischarge to assess symptoms of PTSD. Heart rate in the ambulance, emergency room, and burn unit were obtained by retrospective medical chart review. RESULTS: Pearson correlations revealed a significant relationship between HR in the ambulance (r = 0.32, P = .016) and burn unit (r = 0.30, P = .001) and ASD scores at baseline. Heart rate in the ambulance was related to PTSD avoidance cluster scores at 1, 6, 12, and 24 months. In women, HR in the ambulance was correlated with PTSD scores at 6 (r = 0.65, P = .005) and 12 (r = 0.78, P = .005) months. When covariates (gender, ß-blockers, Brief Symptom Inventory Global Severity Index score) were included in multivariate linear regression analyses, ambulance HR was associated with ASD and PTSD scores at baseline and 1 month, and the interaction of ambulance HR and gender was associated with PTSD scores at 6 and 12 months. Multivariate logistic regression results were similar at baseline and 12 months, which included an HR association yet no interaction at 6 months and a marginal interaction at 1 month. CONCLUSIONS: While peritraumatic HR is most robustly associated with PTSD symptom severity, HR on admission to burn unit also predicts the development of ASD. Gender and avoidance symptoms appear particularly salient in this relationship, and these factors may aid in the identification of subgroups for which HR serves as a biomarker for PTSD. Future work may identify endophenotypic measures of increased risk for PTSD, targeting subgroups for early intervention.
