Trauma-related correlates of alcohol use in recently deployed OEF/OIF veterans

Associations between symptoms of posttraumatic stress disorder, pain, and alcohol use disorder among OEF/OIF/OND veterans

BACKGROUND

Alcohol use disorder (AUD) is prevalent among Operation Enduring Freedom, Operation Iraqi Freedom, and Operation New Dawn (OEF/OIF/OND) veterans. Pain and posttraumatic stress disorder (PTSD) are highly comorbid and increase risk of AUD. Prior studies linking pain or PTSD to AUD have not explored interactions between pain and PTSD symptoms.

METHODS

OEF/OIF/OND veterans (N = 1230) were recruited from social media websites for a cross-sectional study of health behavior. Pain was assessed using the Pain Outcomes Questionnaire. PTSD symptoms and PTSD symptom clusters were assessed using the Posttraumatic Stress Disorder Checklist for DSM-5. AUD symptoms were assessed with the AUD Identification Test. Linear regression models were used to test for main and interaction effects in the full sample and separately by sex.

RESULTS

Both pain and PTSD symptoms were associated with increased AUD symptomology, though the relationship between pain and AUD was heighted at relatively low PTSD symptoms. With respect to PTSD symptom clusters, re-experiencing and negative cognitions and mood were associated with increased AUD symptomology. Interactions between pain and re-experiencing as well as pain and avoidance were revealed. Results for men mirrored the full sample, while an interaction between pain and negative cognitions and mood was associated with AUD in women.

CONCLUSIONS

Results highlight associations between AUD, PTSD symptoms, and pain among veterans. While the relationship between pain and AUD appeared stronger in the context of low PTSD symptoms, both pain and PTSD symptoms were associated with increased AUD. Clinicians treating veterans with AUD should address the range of potential comorbidities.

Determinants of new-onset alcohol use disorder in U.S. military veterans: Results from the National Health and Resilience in Veterans Study

BACKGROUND

Although veterans are at increased risk of alcohol use disorder (AUD) relative to civilians, few longitudinal studies have examined both risk and protective factors that influence the development of AUD. This study aimed to identify risk and protective factors that contribute to incident AUD.

METHODS

Data were analyzed from the National Health and Resilience in Veterans Study (NHRVS), a nationally representative, prospective cohort study of U.S. veterans. The sample included 1,770 veterans who did not meet criteria for lifetime AUD at Wave 1 and completed at least one follow-up assessment over a 7-year period. Veterans completed self-report measures to assess for risk and protective factors. A multivariable binary logistic regression analysis was conducted to examine baseline factors associated with incident AUD.

RESULTS

A total of 5.9% of veterans without AUD at Wave 1 developed AUD in the 7-year follow-up period. Adult sexual trauma, greater severity of anxious arousal symptoms of PTSD, lifetime history of drug and nicotine use disorders, and higher alcohol consumption at Wave 1 were independently associated with incident AUD. Lifetime drug use disorder (75.9%) and higher alcohol consumption (22.1%) explained the most variance in incident AUD.

CONCLUSION

Approximately 6% of veterans without AUD at Wave 1 developed AUD over a 7-year period. Lifetime drug use disorder and greater alcohol consumption at baseline, as well as trauma-related characteristics (i.e., adult sexual trauma, anxious arousal symptoms), were associated with increased risk of developing AUD. Future research should examine whether treatment of drug use disorder and PTSD symptoms in at-risk veterans may help mitigate risk of developing AUD in this population.

A Review of Military Health Research Using a Social–Ecological Framework

Objective:

We aim to contextualize the growing body of research on the sequelae of military service in the wars in Afghanistan and Iraq. We employ a social–ecological (SE) framework for the taxonomy of military health research and classify risk as arising from the individual, family, community, and the institutional levels. We intend for this review to inform enhanced health promotion efforts in military communities.

Data Source:

Articles reviewed were extracted from Web of Science, PubMed, and Scopus.

Inclusion and Exclusion Criteria:

Research focused on somatic and psychological sequelae of combat deployment published from 2001—the year the war in Afghanistan began—through the end of 2014. We excluded studies of non-US military personnel, other systematic reviews, meta-analyses, book chapters, and theoretical papers.

Data Extraction:

We examined and summarized the aims, participants, methods, study design, SE framework tier, risk factors, and health outcomes.

Data Synthesis:

Studies were categorized according to SE tier, whether they focused on somatic, behavioral, or psychological outcomes, and by risk factor.

Results:

Of the 352 peer-reviewed papers, 84% focused on war’s sequelae on the index military personnel, and 75% focused on mental or behavioral health outcomes—mostly on post-traumatic stress disorder. We find comparatively little research focusing on the family, community, or institutional tiers.

Conclusions:

We know relatively little about how family and community respond to the return of personnel from combat deployment; how family resources affect the health of returning military personnel; and how a war’s persistence presents challenges for federal, state, and local agencies to meet military health-care needs. Such work is especially salient as US troops return home from war—particularly in communities where there are substantial military populations.

Web-based alcohol intervention for veterans: PTSD, combat exposure, and alcohol outcomes

OBJECTIVE

The purpose of the current study was to evaluate the relationship between baseline levels of posttraumatic stress disorder (PTSD), combat exposure, and alcohol outcomes in a sample of Operation Enduring Freedom (OEF) and Operation Iraqi Freedom (OIF) veterans using a web-based self-management intervention (VetChange) for problem drinking.

METHOD

The current study focuses on 523 veterans who participated in a larger randomized clinical trial. Analyses in the current study include (a) multivariable linear regression models to assess the relationship between PTSD, combat exposure, and alcohol variables at baseline, and (b) general linear models accounting for correlated data within subjects to analyze change over time for alcohol outcomes as a function of baseline PTSD symptoms, combat exposure, and covariates.

RESULTS

There was a positive association between PTSD symptom severity and alcohol use and alcohol problem severity at baseline. However, participants with higher baseline PTSD symptoms demonstrated a significantly greater reduction in alcohol use during the intervention and a greater reduction in alcohol problems from baseline to 3-month follow-up. Combat exposure severity was positively associated with alcohol problems at baseline. However, veterans with higher exposure demonstrated a greater reduction in average weekly drinking between end of intervention and follow-up, and otherwise showed changes similar to participants with lower exposure.

CONCLUSIONS

Higher levels of baseline PTSD symptoms and combat exposure severity did not prevent OEF/OIF veterans from achieving positive alcohol outcomes through participation in a self-management web intervention for problem drinking. (PsycINFO Database Record

Latent-level relations between DSM-5 PTSD symptom clusters and problematic smartphone use

Common mental health consequences following the experience of potentially traumatic events include Posttraumatic Stress Disorder (PTSD) and addictive behaviors. Problematic smartphone use is a newer manifestation of addictive behaviors. People with anxiety severity (such as PTSD) may be at risk for problematic smartphone use as a means of coping with their symptoms. Unique to our knowledge, we assessed relations between PTSD symptom clusters and problematic smartphone use. Participants (N = 347), recruited through Amazon's Mechanical Turk (MTurk), completed measures of PTSD and smartphone addiction. Results of the Wald tests of parameter constraints indicated that problematic smartphone use was more related to PTSD's negative alterations in cognitions and mood (NACM) than to PTSD's avoidance factor, Wald χ²(1, N = 347) = 12.51, p = 0.0004; and more to PTSD's arousal compared to PTSD's avoidance factor, Wald χ²(1, N = 347) = 14.89, p = 0.0001. Results indicate that problematic smartphone use is most associated with negative affect and arousal among trauma-exposed individuals. Implications include the need to clinically assess problematic smartphone use among trauma-exposed individuals presenting with higher NACM and arousal severity; and targeting NACM and arousal symptoms to mitigate the effects of problematic smartphone use.

Military sexual trauma, combat exposure, and negative urgency as independent predictors of PTSD and subsequent alcohol problems among OEF/OIF veterans

This study tested a path model of relationships between military sexual trauma (MST), combat exposure, negative urgency, posttraumatic stress disorder (PTSD) symptoms, and alcohol use and related problems. The sample consisted of 86 Operation Enduring Freedom/Operation Iraqi Freedom (OEF/OIF) veterans who reported drinking at least one alcoholic beverage per week. PTSD mediated the relationships between MST and alcohol-related problems, negative urgency and alcohol-related problems, and combat exposure and alcohol-related problems. In addition, negative urgency had a direct effect on alcohol problems. These results indicate that MST, combat exposure, and negative urgency independently predict PTSD symptoms and PTSD symptoms mediate their relationship with alcohol-related problems. Findings support previous literature on the effect of combat exposure and negative urgency on PTSD and subsequent alcohol-related problems. The current study also contributes to the limited research regarding the relationship between MST, PSTD, and alcohol use and related problems. Clinical interventions aimed at reducing emotional dysregulation and posttraumatic stress symptomology may subsequently improve alcohol-related outcomes.

Psychiatric symptoms of Turkish combat-injured non-professional veterans

BACKGROUND

It is well-known that exposure to combat puts individuals at risk for developing adverse psychological problems, including posttraumatic stress disorder (PTSD), depression, anxiety, and health-related behaviour problems and that the presence of combat-related injury increases the risk for psychopathology. Little is known, however, about the consequences of combat among conscripted soldiers fighting against terrorism in their homeland.

OBJECTIVE

The main aim of the current study was to examine the prevalence of probable PTSD, severity of PTSD symptoms, depression, anxiety, and PTSD-related functional impairment among Turkish combat-injured, non-professional veterans. In addition, investigated were also the possible differences among the symptoms of PTSD, depression, and anxiety of the veterans by the frequency of current cigarette and alcohol use.

METHODS

A total of 366 male veterans were assessed by using a demographic information form, which obtained information about injury status and health behaviours, the Posttraumatic Stress Diagnostic Scale (PDS), and the Brief Symptom Inventory (BSI). Symptom frequency and multivariate analysis of variances (MANOVA) were used to analyse the data.

RESULTS

The prevalence of probable PTSD was 46.7% (171) among Turkish veterans while 16.4% experienced severe depression and 18% experienced severe anxiety. "Upset at reminders (65.8%)" was the most common PTSD symptom. "Responsibilities related to home (48.4%)" was the most frequently reported PTSD-related functional impairment. Results indicated that veterans who smoke more than half a pack per day scored significantly higher in severity of PTSD symptoms, depression, and anxiety. Contrary to expectations, there was no significant difference in symptoms of PTSD, depression, and anxiety related to the frequency of current alcohol use.

CONCLUSION

Turkish non-professional veterans with physical injuries have serious psychiatric problems an average of 13 years after a combat experience. Psychiatric and psychosocial services to Turkish non-professional veterans are a substantial and ongoing need.

The moderating role of dysphoria in the relationship between intrusions and alcohol use

Posttraumatic Stress Disorder (PTSD) is frequently comorbid with alcohol use disorders (AUD; Calabrese et al., 2011; McFall, Mackay, & Donovan, 1992). Among several explanations for this comorbidity, the most empirically supported is the self-medication theory which postulates that substances are used to medicate PTSD-related distress (Keane & Wolfe, 1990; Khantzian, 1985; Stewart, 1996). The current study examines the effects of trauma-related distress on alcohol use (total drinking days, drinks per drinking day, heavy drinking days) in a sample of 127 trauma-exposed Veterans following deployment to Iraq or Afghanistan. The dysphoria symptoms of PTSD were used as an indicator of distress, and examined as a moderator in the relationship between intrusion symptoms of PTSD and alcohol use. The proposed moderation model was tested using cross-sectional data from the first month following return from deployment, and at 6 months and at 12 months post-deployment. Results showed that dysphoria symptoms significantly moderated relations between intrusions and total drinking days and heavy drinking days at one month post-deployment; however, a significant pattern was not demonstrated at 6 months and 12 months. Further, dysphoria did not moderate the relation between intrusion symptoms and drinks per drinking day at the three time points. Theoretical and clinical implications are subsequently discussed.

Food insecurity in veteran households: findings from nationally representative data

Objective

The present study is the first to use nationally representative data to compare rates of food insecurity among households with veterans of the US Armed Forces and non-veteran households.

Design

We used data from the 2005–2013 waves of the Current Population Survey – Food Security Supplement to identify rates of food insecurity and very low food security in veteran and non-veteran households. We estimated the odds and probability of food insecurity in veteran and non-veteran households in uncontrolled and controlled models. We replicated these results after separating veteran households by their most recent period of service. We weighted models to create nationally representative estimates.

Setting

Nationally representative data from the 2005–2013 waves of the Current Population Survey – Food Security Supplement.

Subjects

US households (n388 680).

Results

Uncontrolled models found much lower rates of food insecurity (8·4 %) and very low food security (3·3 %) among veteran households than in non-veteran households (14·4 % and 5·4 %, respectively), with particularly low rates among households with older veterans. After adjustment, average rates of food insecurity and very low food security were not significantly different for veteran households. However, the probability of food insecurity was significantly higher among some recent veterans and significantly lower for those who served during the Vietnam War.

Conclusions

Although adjusting eliminated many differences between veteran and non-veteran households, veterans who served from 1975 and onwards may be at higher risk for food insecurity and should be the recipients of targeted outreach to improve nutritional outcomes.

Associations between deployment, military rank, and binge drinking in active duty and Reserve/National Guard US servicewomen

BACKGROUND

Prior studies of mostly male U.S. service members suggest service characteristics such as deployment with combat exposure and lower rank may be a risk factor for alcohol misuse. However, these relationships have not been examined among servicewomen who may be at high risk for experiencing deployment-related stressors and associated health consequences. This cross-sectional report of US servicewomen in the Reserve or National Guard (RNG) and active component (AC) sought to examine these associations.

METHODS

A Midwestern community sample of currently serving and veteran servicewomen (N=1339) completed structured telephone interviews. The Generalized Linear Model was used to examine associations between service characteristics, any binge drinking, and frequency of recent binge drinking after adjusting for demographics.

RESULTS

After adjusting for demographics, deployment to Iraq or Afghanistan was associated with greater odds of reporting a binge drinking episode, compared to no deployment, among servicewomen in the AC but not RNG. Deployment to Iraq or Afghanistan was also associated with more days binge drinking in both groups compared to servicewomen not deployed. Lower ranking servicewomen also reported higher odds of a binge drinking episode and higher frequency of binge drinking in both the RNG and AC.

CONCLUSIONS

Service characteristics including deployment to Iraq or Afghanistan (vs. those not deployed) and lower rank (vs. officers) may be a risk factor for recent binge drinking and higher frequency of binge drinking among servicewomen, after adjusting for demographic covariates. Public health and clinical implications are discussed.
