Caffeine Use in Military Personnel With PTSD: Prevalence and Impact on Sleep

ABSTRACTBackground: Caffeine use is highly prevalent among active duty military personnel and can be beneficial to performance in the short term. However, regular caffeine use has been found to contribute to sleep disturbances, which are elevated among the significant number of military personnel with posttraumatic stress disorder (PTSD). The current study is the first to examine caffeine use and its relationship with sleep disturbances in military personnel seeking treatment for PTSD. Participants: Active duty military personnel (N = 366) who had returned from deployments to Afghanistan or Iraq and were seeking treatment for PTSD. Methods: Pearson correlations were used to examine the relationships between caffeine use, sleep disturbances, and PTSD symptom clusters. Results: The majority of the sample (89%) reported some caffeine use, with coffee being the largest contributor to total caffeine intake. Contrary to hypotheses, higher caffeine use was associated with lower insomnia symptom severity; follow-up analysis indicated that this was due to elevated insomnia symptom severity in those reporting no caffeine use. Caffeine use was not associated with any other measures of sleep disturbance or with PTSD symptoms. Conclusions: Caffeine use was not associated with greater reported sleep disturbances in this sample, possibly because those with elevated insomnia symptom severity abstained from any caffeine, or because insomnia symptoms were elevated in this sample.

Treatment of Adolescent PTSD: The Impact of Prolonged Exposure Versus Client-Centered Therapy on Co-Occurring Emotional and Behavioral Problems.

The present study evaluated secondary emotional and behavioral outcomes among adolescents who received prolonged exposure (PE-A) or client-centered therapy (CCT) for posttraumatic stress disorder (PTSD) in a randomized controlled trial. Participants were 61 adolescent girls (age: M = 15.33, SD = 1.50 years) with sexual abuse related PTSD seeking treatment at a community mental health clinic. Multilevel modeling was employed to evaluate group differences on the Youth Self-Report (YSR) over acute treatment and 12-month follow-up. Both treatment groups showed significant improvements on all YSR scales from baseline to 12-month follow-up. Adolescents who received PE-A showed significantly greater reductions than those receiving CCT on the Externalizing subscale (d = 0.70), rule-breaking behavior (d = 0.63), aggressive behavior (d = 0.62), and conduct problems (d = 0.78). No treatment differences were found on the Internalizing subscale or among other YSR problem areas. Both PE-A and CCT effectively reduced many co-occurring problems among adolescents with PTSD. Although PE-A focuses on PTSD and not on disruptive behaviors, PE-A was associated with greater sustained changes in externalizing symptoms, supporting broad effects of trauma-focused treatment on associated problem areas.

The impact of social support, unit cohesion, and trait resilience on PTSD in treatment-seeking military personnel with PTSD: The role of posttraumatic cognitions

BackgroundThe personal resources of social support, unit cohesion, and trait resilience have been found to be associated with posttraumatic stress disorder (PTSD) severity among military personnel. However, the underlying mechanisms of these relationships are unclear. We hypothesized that negative posttraumatic cognitions, which are associated with PTSD, mediate the relationships between these personal resources and PTSD. MethodsThe relationship between PTSD symptom severity and a latent factor comprised of social support, unit cohesion, and trait resilience was evaluated using cross-sectional data from 366 treatment-seeking active duty military personnel with PTSD following deployments to or near Iraq or Afghanistan. Structural equation modeling (SEM) was used to test whether posttraumatic cognitions mediated this relationship. ResultsThe SEM model indicated that (1) a robust latent variable named personal resources (indicated by social support, unit cohesion, and trait resilience) was negatively associated with PTSD severity; (2) personal resources were negatively associated with negative posttraumatic cognitions; (3) negative posttraumatic cognitions fully mediated the association between personal resources and PTSD severity. The final SEM mediation model showed a highly satisfactory fit [χ2 (22) = 16.344, p = 0.798; χ2/df = 0.743; CFI = 1; RMSEA = 0.000]. ConclusionsThese findings suggest that among active duty military personnel seeking treatment for PTSD, personal resources (social support, unit cohesion, and trait resilience) may mitigate PTSD severity by reducing negative posttraumatic cognitions.

Predicting engagement in psychotherapy, pharmacotherapy, or both psychotherapy and pharmacotherapy among returning veterans seeking PTSD treatment.

Both pharmacotherapy and psychotherapy are effective treatments for posttraumatic stress disorder (PTSD). Better understanding factors that are associated with engaging in these different treatment options may improve treatment utilization and outcomes. This issue is especially important among veterans returning from Iraq and Afghanistan, given high rates of those seeking PTSD treatment. This study examined potential predictors of the type of treatment (psychotherapy, pharmacotherapy, or both) 232 returning veterans (92% male, mean age = 33.38) engaged in within 1 year of seeking treatment at a VA PTSD clinic. Results indicated that 32.3% of returning veterans engaged in pharmacotherapy only, 23.7% engaged in psychotherapy only, and 44.0% engaged in both. Veterans who engaged in pharmacotherapy only or in both pharmacotherapy and psychotherapy had higher pretreatment PTSD and depression symptoms than did those who engaged in psychotherapy only. History of pharmacotherapy treatment was associated with engagement in pharmacotherapy only or both pharmacotherapy and psychotherapy, as compared with psychotherapy only. Treatment engagement type was not significantly associated with differences in age, gender, race/ethnicity, service branch, alcohol use/misuse, history of psychotherapy, distance from the VA, or PTSD service connection. Implications for enhancing PTSD treatment engagement are discussed. (PsycINFO Database Record

Psychometric analysis of the PTSD Checklist-5 (PCL-5) among treatment-seeking military service members.

The Posttraumatic Stress Disorder Checklist (PCL-5; Weathers et al., 2013) was recently revised to reflect the changed diagnostic criteria for posttraumatic stress disorder (PTSD) in the fifth edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-5; American Psychiatric Association, 2013). We investigated the psychometric properties of PCL-5 scores in a large cohort (N = 912) of military service members seeking PTSD treatment while stationed in garrison. We examined the internal consistency, convergent and discriminant validity, and DSM-5 factor structure of PCL-5 scores, their sensitivity to clinical change relative to PTSD Symptom Scale-Interview (PSS-I; Foa, Riggs, Dancu, & Rothbaum, 1993) scores, and their diagnostic utility for predicting a PTSD diagnosis based on various measures and scoring rules. PCL-5 scores exhibited high internal consistency. There was strong agreement between the order of hypothesized and observed correlations among PCL-5 and criterion measure scores. The best-fitting structural model was a 7-factor hybrid model (Armour et al., 2015), which demonstrated closer fit than all other models evaluated, including the DSM-5 model. The PCL-5's sensitivity to clinical change, pre- to posttreatment, was comparable with that of the PSS-I. Optimally efficient cut scores for predicting PTSD diagnosis were consistent with prior research with service members (Hoge, Riviere, Wilk, Herrell, & Weathers, 2014). The results indicate that the PCL-5 is a psychometrically sound measure of DSM-5 PTSD symptoms that is useful for identifying provisional PTSD diagnostic status, quantifying PTSD symptom severity, and detecting clinical change over time in PTSD symptoms among service members seeking treatment.

Physical Activity Moderates the Association Between Pain and PTSD in Treatment-Seeking Veterans.

Posttraumatic stress disorder (PTSD) and pain are frequently comorbid conditions that can result in bidirectional exacerbations. Initial research suggests physical activity may prevent PTSD symptoms or assist with recovery. Unfortunately, Veterans with PTSD are less likely to engage in physical activity, often citing pain as a primary reason. The current study examines the potential role of physical activity as a moderator of the pain and PTSD relationship. Data were collected from 239 Veterans who were seeking PTSD treatment at a Veterans Affairs (VA) hospital between 2006 and 2013. Veterans completed the Clinician-Administered PTSD Scale (CAPS) to measure PTSD severity and self-report inventories to measure pain and physical activity. Multiple moderated linear regressions were used to examine the influence of physical activity on the relationship between pain and PTSD symptoms. Pain severity and interference were associated with more severe PTSD. Physical activity did not have main effects on PTSD severity. However, it did moderate the relationship between PTSD and pain, such that those who were active, despite high levels of pain severity or pain interference, had fewer PTSD symptoms. For Veterans seeking treatment for PTSD, physical activity was particularly salient for those reporting high levels of pain severity and intensity. While assessment of pain is recommended with all Veterans, it may also be beneficial to evaluate physical activity in those with prominent pain complaints. Further examination of the role of exercise in integrated care for pain and PTSD is warranted.

Does Reintegration Stress Contribute to Suicidal Ideation Among Returning Veterans Seeking PTSD Treatment?

Although posttraumatic stress disorder (PTSD) and other psychiatric symptoms are well-established risk factors for suicidal ideation among returning veterans, less attention has been paid to whether the stress of reintegrating into civilian society contributes to suicidal ideation. Utilizing a sample of 232 returning veterans (95% male, mean age = 33.63 years) seeking PTSD treatment, this study tested whether reintegration difficulties contribute to suicidal ideation over and above the influence of PTSD symptoms, depression symptoms, and potential substance misuse. Logistic regressions indicated that reintegration stress had a unique effect on suicidal ideation over and above PTSD and depression symptoms. Reintegration stress interacted with substance misuse to predict suicidal ideation, such that the effect of reintegration stress on suicidal ideation was much larger for those with potential substance misuse. Exploratory analyses also examined which types of reintegration difficulties were associated with suicidal ideation, and found that difficulty maintaining military friendships, difficulty getting along with relatives, difficulty feeling like you belong in civilian society, and difficulty finding meaning/purpose in life were all significantly associated with suicidal ideation, beyond the effects of psychiatric symptoms and potential substance misuse. Findings highlight the importance of addressing reintegration stress for the prevention of suicide among returning veterans. Implications for treatment are discussed.

Obstructive Sleep Apnea and Posttraumatic Stress Disorder among OEF/OIF/OND Veterans.

This study examined: (a) the relationship between self-reported posttraumatic stress disorder (PTSD) symptoms and risk of obstructive sleep apnea (OSA) in a younger, Iraq and Afghanistan (OEF/OIF/OND) veteran sample seeking treatment for PTSD; and (b) the relationships between PTSD symptom scores and each risk factor of OSA (snoring, fatigue, high blood pressure/BMI). Participants were 195 Iraq and Afghanistan veterans presenting to a VA outpatient PTSD clinic for evaluation. Veterans were 21 to 59 years old (mean 33.40, SD 8.35) and 93.3% male (n = 182). Logistic regressions were run to examine whether veterans with greater PTSD symptom severity had an increased probability of screening as high risk for OSA, even after controlling for known risk factors (older age, positive smoking status, and use of CNS depressants). Of 159 veterans screened, 69.2% were assessed as being at high risk for OSA. PTSD symptom severity increased the risk of screening positive for OSA. PTSD symptom severity increased risk of screening positive for snoring and fatigue, but not high blood pressure/BMI. OEF/OIF/OND veterans with PTSD screen as high risk for OSA at much higher rates than those seen in community studies and may not show all classic predictors of OSA (i.e., older and higher BMI). This study is the first to suggest that the Berlin may be a useful screener for OSA in a younger OEF/OIF/OND veteran population with PTSD. Screening of younger veterans with PTSD for OSA should be standard care, and polysomnography and OSA interventions should be readily available to younger veterans.

Resilient but addicted: The impact of resilience on the relationship between smoking withdrawal and PTSD

Nicotine use is common among people with posttraumatic stress disorder (PTSD). Resilience, which is reflected in one's ability to cope with stress, has been shown to be associated with lower cigarette smoking and posttraumatic stress symptoms, but relationships among these three variables have not been examined. This study investigates the relationships of resilience and nicotine withdrawal with each other and in relation to PTSD symptoms. Participants were 118 cigarette smokers with PTSD seeking treatment for PTSD and nicotine use. Data were randomly cross-sectionally sampled from three time points: week 0, week 12, and week 27 of the study. Hierarchical multiple regression analyses revealed main effects of both resilience and nicotine withdrawal symptoms on PTSD severity, controlling for the sampled time point, negative affect, and expired carbon monoxide concentration. Consistent with prior research, PTSD severity was higher among individuals who were less resilient and for those who had greater nicotine withdrawal. There was an interaction between resilience and nicotine withdrawal on self-reported PTSD severity, such that greater resilience was associated with lower PTSD severity only among participants with low nicotine withdrawal symptoms. Among individuals with high nicotine withdrawal, PTSD severity was high, regardless of resilience level. These results suggest that resilience is a protective factor for PTSD severity for those with low levels of nicotine withdrawal, but at high levels of nicotine withdrawal, the protective function of resilience is mitigated.

Post-Traumatic Stress Disorder and Quality-of-Life Outcomes of Veterans Seeking Treatment in a Residential Rehabilitation Treatment Program

The purpose of this study was to determine the clinical utility of the Quality of Life Inventory (QOLI) in a sample of veterans with post-traumatic stress disorder (PTSD). Limited research has examined the quality of life of veterans with combat- and non-combat-related PTSD seeking treatment at a Veterans Affairs Medical Center (VAMC) residential rehabilitation treatment program (RRTP). This study investigated the difference in PTSD symptom severity and quality of life following successful completion of an RRTP using the PTSD Checklist (PCL) and the QOLI, and whether there is a differential treatment effect due to type of trauma exposure (i.e., combat-related and non-combat-related event). Findings suggest that veterans completing treatment at a VAMC RRTP demonstrate overall significant decreases in PTSD symptoms and improvement in their quality of life, with type of trauma exposure having no significant effect on treatment outcome.

The Role of Alcohol Expectancies in Drinking Behavior among Women with Alcohol Use Disorder and Comorbid Posttraumatic Stress Disorder

Understanding how alcohol expectancies relate to alcohol use among individuals with concurrent alcohol use disorder (AUD) and Posttraumatic Stress Disorder (PTSD) is important to understanding and treating this comorbidity. This study examined the role of positive and negative alcohol expectancies and PTSD symptoms in drinking behavior in a comorbid female sample. Participants were women (n = 33; 56% Caucasian) seeking AUD and PTSD treatment in an outpatient community co-occurring disorders program. Hypotheses related to drinking days and alcohol problems outcomes were evaluated using negative binomial hierarchical regression. PTSD symptoms were associated with fewer reported days of alcohol-related problems. Negative expectancies related to negative changes in social behavior associated with drinking days and cognitive and motor impairment associated with problems. Both the general positive expectancies score and specific global positive change subscale were uniquely associated with drinking and alcohol-related problems days after controlling for PTSD symptom severity and negative expectancies scores. Results suggest that both negative and positive expectancies about alcohol’s effects are important correlates of drinking behavior among women with AUD and PTSD, with positive expectancies playing a potentially more salient role on use and consequences than symptom severity and negative expectancies.

Associations Between Perceived Social Reactions to Trauma‐Related Experiences With PTSD and Depression Among Veterans Seeking PTSD Treatment

The Social Acknowledgment Questionnaire (SAQ; Maercker & Mueller, ) is a measure of trauma survivors' perceptions of social acknowledgment and disapproval from others, and these factors are shown to be associated with posttraumatic stress disorder (PTSD) among civilian trauma survivors. This study seeks to validate the structure of the SAQ among U.S. military veterans and test the hypothesis that family and general disapproval are associated with PTSD and depression among veterans. Participants were 198 U.S. veterans who experienced military trauma and completed an intake evaluation through a Veterans Affairs PTSD treatment program. Structural equation modeling (SEM) results supported a well-fitting 3-factor model for the SAQ that was similar to prior studies in capturing the constructs of social acknowledgment, general disapproval, and family disapproval. SEM results also showed that all 3 of the SAQ factors were associated with veterans' depression (-.31, .22, and .39, respectively), whereas only general disapproval was related to veterans' PTSD. This is the first study of which we are aware to investigate the factor structure of the SAQ in a veteran sample and to investigate the relationship between SAQ factors and trauma survivors' depression. Results build upon prior findings by showing the importance of positive and negative social reactions to veterans' traumatic experiences.

Treatment-Seeking Barriers for Veterans of the Iraq and Afghanistan Conflicts Who Screen Positive for PTSD

Barriers associated with the decision not to seek treatment for symptoms of combat-related posttraumatic stress disorder (PTSD) were examined. Participants were 143 military men and women who served in Operation Enduring Freedom or Operation Iraqi Freedom (OEF/OIF) and who screened positive for posttraumatic stress disorder (PTSD), as assessed by the PTSD Checklist-Military Version, and who had not sought treatment for PTSD. During a cognitive-behavioral telephone intervention, participants were asked about their beliefs concerning seeking PTSD treatment. Four categories of beliefs were associated with the decision to seek treatment, including concerns about treatment (40%), emotional readiness for treatment (35%), stigma (16%), and logistical issues (8%). This work suggests areas for intervention efforts to minimize barriers to treatment for PTSD for OEF/OIF veterans.

Ethnic differences in symptoms among female veterans diagnosed with PTSD

Among U.S. male Vietnam veterans, Hispanics have been shown to have higher rates of posttraumatic stress disorder (PTSD) than African Americans and non-Hispanic Whites (Kulka et al., 1990). In terms of gender, Tolin and Foa's (2006) meta-analysis suggested women experience higher rates of PTSD than men. This study examined ethnic differences in PTSD and other symptomatology among 398 female veterans (63% non-Hispanic White, 28% Hispanic, 9% African American) seeking treatment for PTSD from 1995 to 2009 at a Veterans Administration (VA) behavioral health clinic. The following symptom clusters were examined: anxiety/PTSD, depression, anger/hostility, and psychotic/dissociative symptoms. Few differences were found among the groups, suggesting the 3 ethnic groups studied were more similar than different. African American female veterans, however, scored higher on measuring ideas of persecution/paranoia, although this may reflect an adaptive response to racism. These findings warrant further investigation to elucidate this relationship.

Demographic and social adjustment characteristics of patients with comorbid posttraumatic stress disorder and alcohol dependence: Potential pitfalls to PTSD treatment

The present study examined the demographic and social adjustment characteristics of a sample seeking treatment for comorbid posttraumatic stress disorder (PTSD) and alcohol dependence (AD). Using descriptive statistics, we compared the characteristics of this group to those of a sample seeking treatment for PTSD alone and to another sample seeking treatment for AD alone. Results indicated that compared to the PTSD alone and AD alone samples, a greater percentage of the comorbid sample was unemployed, with low income and living without the support of a spouse or intimate partner. Further, participants in the comorbid sample were less likely than those in the PTSD alone sample to have received more than a high school education, though the comorbid and AD samples were comparable on education level. These results are discussed with attention to how poor social adjustment may place comorbid AD–PTSD patients at greater risk for premature termination of therapy, particularly when that treatment is focused on alleviating PTSD symptoms. Suggestions are made to enhance retention of these difficult patients in treatment programs.

Racial differences on psychological measures in combat veterans seeking treatment for PTSD.

In this article, we examined racial differences in psychometric data on 4 commonly used self-report inventories administered to a group of 206 combat veterans evaluated at a Veterans Affairs Medical Center outpatient posttraumatic stress disorder (PTSD) treatment program. Patients completed the Beck Depression Inventory, Mississippi Scale for Combat-Related PTSD, Dissociative Experiences Scale (DES), and Minnesota Multiphasic Personality Inventory-2 (MMPI-2). Black veterans showed greater elevations than White veterans on the DES, and the F-K index and Scales 6 and 8 of the MMPI-2. In addition, normative data are presented for the entire sample on each measure. Results suggest that, consistent with studies using the original MMPI, these patients endorse severe levels of psychopathology across a broad range of symptoms, including depression and disturbed thinking. Implications for clinical practice and future research are addressed.
