Anger and Posttraumatic Stress Disorder Symptom Severity in a Trauma-Exposed Military Population: Differences by Trauma Context and Gender

Effects of prior deployments and perceived resilience on anger trajectories of combat-deployed soldiers

BACKGROUND

Problematic anger is frequently reported by soldiers who have deployed to combat zones. However, evidence is lacking with respect to how anger changes over a deployment cycle, and which factors prospectively influence change in anger among combat-deployed soldiers.

METHODS

Reports of problematic anger were obtained from 7298 US Army soldiers who deployed to Afghanistan in 2012. A series of mixed-effects growth models estimated linear trajectories of anger over a period of 1-2 months before deployment to 9 months post-deployment, and evaluated the effects of pre-deployment factors (prior deployments and perceived resilience) on average levels and growth of problematic anger.

RESULTS

A model with random intercepts and slopes provided the best fit, indicating heterogeneity in soldiers' levels and trajectories of anger. First-time deployers reported the lowest anger overall, but the most growth in anger over time. Soldiers with multiple prior deployments displayed the highest anger overall, which remained relatively stable over time. Higher pre-deployment resilience was associated with lower reports of anger, but its protective effect diminished over time. First- and second-time deployers reporting low resilience displayed different anger trajectories (stable v. decreasing, respectively).

CONCLUSIONS

Change in anger from pre- to post-deployment varies based on pre-deployment factors. The observed differences in anger trajectories suggest that efforts to detect and reduce problematic anger should be tailored for first-time v. repeat deployers. Ongoing screening is needed even for soldiers reporting high resilience before deployment, as the protective effect of pre-deployment resilience on anger erodes over time.

A Comparison of Group Anger Management Treatments for Combat Veterans With PTSD: Results From a Quasi-Experimental Trial

Difficulty controlling anger is a significant concern among combat veterans with posttraumatic stress disorder (PTSD), yet few controlled studies have examined the efficacy of anger treatments for this population. This study examined the effects of a group cognitive behavioral therapy (CBT) intervention compared with a group present-centered therapy (PCT) control condition in male and female combat veterans with PTSD. Thirty-six combat veterans with PTSD and anger difficulties began group treatment (CBT, n = 19; PCT, n = 17). Separate multilevel models of self-rated anger, PTSD symptoms, and disability were conducted using data from baseline, each of 12 treatment sessions, posttreatment, and 3- and 6-month follow-up time points. Significant decreases in anger and PTSD symptoms were observed over time, but no significant differences between CBT and PCT were observed on these outcomes. A significant interaction of therapy by time favoring the PCT condition was observed on disability scores. Gender differences were observed in dropout rates (i.e., 100% of female participants dropped out of CBT). Findings suggest that both CBT and PCT group therapy may be effective in reducing anger in combat veterans with PTSD. Results also highlight potential gender differences in response to group anger treatment.

Is deployment status the critical determinant of psychosocial problems among reserve/guard soldiers?

A general assumption that deployment is the primary catalyst for psychological and social difficulties may contribute to underrecognition and undertreatment of problems among never-deployed service members (i.e., having no history of ever being deployed). We aimed to determine if ever-deployed (i.e., having a history of at least one deployment) and never-deployed United States Army Reserve and National Guard (USAR/NG) soldiers differed in mental health, substance use, and resiliency factors, and to determine the relative influence of deployment status and each of these factors on poor psychosocial outcomes. We analyzed a subset of data from Operation: SAFETY (Soldiers and Families Excelling Through the Years) (N = 404), an ongoing study examining the health and well-being of USAR/NG soldiers. Bivariate analyses demonstrated that soldiers did not significantly differ across a range of measures on the basis of deployment status (ps > 0.05). In fact, Factor Analyses and Discriminant Function Analysis revealed that deployment status was the least salient factor to psychosocial problems among the measured variables and that the observed variables could not accurately discriminate between ever-deployed and never-deployed soldiers, F(8, 374) = 1.34, p > .05. Measures of mental health and substance use were more salient to psychosocial problems (ps < .05). Measures of resiliency loaded negatively onto psychosocial problems (ps < .05), indicating that they contribute to better well-being. Targeting screening and intervention efforts only on soldiers who have been deployed will miss opportunities to intervene on an equally affected group. Resiliency factors should be considered as intervention targets. (PsycInfo Database Record (c) 2020 APA, all rights reserved).

Problems with Social Acceptance and Social Victimization Predict Substance Use among US Reserve/Guard Soldiers

The effects of negative social interactions/experiences on substance use have largely been studied in civilian populations, but less is known about United States Army Reserve/National Guard (USAR/NG) soldiers-a high-risk group. We examined the associations between problems with social acceptance, social victimization, and substance use among USAR/NG soldiers, and examined potential differences by deployment history. The sample consisted of soldiers who completed baseline and 1-year follow-up assessments (N = 445) of Operation: SAFETY, an ongoing study of USAR/NG soldiers. We examined the effects of baseline problems with social acceptance/social victimization on nonmedical use of prescription drugs (NMUPD), illicit drug use, frequent heavy drinking (FHD), and alcohol problems at follow-up. Significant effects were small in magnitude but consistent in direction. Greater problems with social acceptance were associated with higher odds of NMUPD and illicit drug use. Greater social victimization was associated with higher odds of NMUPD and illicit drug use. There were no differences by deployment history. Problems with social acceptance/social victimization were not associated with FHD or alcohol problems. Problems with social acceptance/social victimization may contribute to drug use among USAR/NG soldiers. Intervention programs should address social issues, regardless of deployment history.

Developing a Measure to Assess Emotions Associated with Never Being Deployed

BACKGROUND

Much research has focused on stress related to deployments; however, a substantial proportion of soldiers never deploy. In a study of 1.3 million veterans, suicide risk was higher among veterans who had never deployed. Thus, not being deployed may have an impact on soldiers' well-being; however, no measures exist to assess emotions regarding non-deployment. We aimed to develop and test an original measure of non-deployment emotions.

METHODS

We examined the Non-Deployment Emotions (NDE) questionnaire, a novel four-item measure of guilt, unit value, unit camaraderie, and unit connectedness in a sample of never-deployed male and female US Army Reserve/National Guard (USAR/NG) soldiers (N = 174). Data are from Operation: SAFETY (Soldiers and Families Excelling Through the Years), an ongoing survey-based study examining the health of USAR/NG soldiers and their partners. The protocol was approved by the Institutional Review Board at the State University of New York at Buffalo. The relationship between each of the items was examined by calculating correlation and alpha coefficients. Latent class analyses tested for the existence of distinct levels of negative emotions related to non-deployment. Negative binomial regression models examined the cross-sectional associations between NDE summary score and each of the following outcomes, separately: anger, anxiety, depression, and post-traumatic stress.

FINDINGS

More than half of never-deployed USAR/NG soldiers expressed negative emotions for having not been deployed. "Guilt," "value," "camaraderie," and "connectedness" were each positively correlated with each other (p < 0.001) and the internal consistency reliability was high (male soldier α = 0.90, female soldier α = 0.93). Latent class analyses revealed a superior three-class model with well-delineated class membership (entropy = 0.93): "Class 1" (low NDE; 47.6%), "Class 2" (moderate NDE; 33.8%), and "Class 3" (high NDE; 18.6%). Regression models demonstrated that greater non-deployment emotions were independently associated with more severe anger (RR = 1.02, 95% CI: 1.01, 1.03, p < 0.001), anxiety (RR = 1.06, 95% CI: 1.01, 1.11, p < 0.05), depression (RR = 1.06, 95% CI: 1.01, 1.11, p < 0.05), and PTSD (RR = 1.10, 95% CI: 1.04, 1.16, p < 0.01).

DISCUSSION

Findings demonstrate that negative emotions regarding non-deployment are prevalent among never-deployed USAR/NG soldiers and that these emotions are related to a mental health. The NDE provides a measure of "guilt," "value," "camaraderie," and "connectedness" specific to non-deployed soldiers and is able to well discriminate between soldiers that have low, moderately, and highly negative non-deployment emotions. These findings suggest that all military personnel, regardless of deployment status, could be at risk for negative outcomes. As with any survey-based study, there is a potential for response bias; however, given the range of responses collected with the NDE, social desirability is unlikely. Further work is needed to confirm our findings in other components of the military and to examine soldiers in the rear detachment.

Assessing the structure and meaningfulness of the dissociative subtype of PTSD

PURPOSE

Studies conducted in the USA, Canada and Denmark have supported the existence of the dissociative PTSD subtype, characterized primarily by symptoms of depersonalization and derealization. The current study aimed to examine the dissociative PTSD subtype in an Eastern European, predominantly female (83.16%) sample, using an extended set of dissociative symptoms.

METHODS

A latent profile analysis was applied to the PTSD and dissociation data from 689 trauma-exposed university students from Slovakia.

RESULTS

Four latent profiles of varying PTSD and dissociation symptomatology were uncovered. They were named non-symptomatic, moderate PTSD, high PTSD and dissociative PTSD. The dissociative PTSD profile showed elevations on depersonalization and derealization, but also the alternative dissociative indicators of gaps in awareness and memory, sensory misperceptions and cognitive and behavioural re-experiencing. The core PTSD symptoms of 'memory impairment' and 'reckless or self-destructive behaviour' were also significantly elevated in the dissociative PTSD profile. Moreover, anxiety and anger predicted membership in the dissociative PTSD profile.

CONCLUSION

The results provide support for the proposal that the dissociative PTSD subtype can be characterized by a variety of dissociative symptoms.
