Veterans' quality of life (QoL) can be drastically affected by posttraumatic stress disorder (PTSD). We compared prolonged exposure therapy (PET) with metacognitive therapy (MCT) in their effects on quality of life (QoL) among veterans with post-traumatic stress disorder (PTSD). Overall, 57 veterans with PTSD were randomly assigned to three groups MCT (N = 17), PET (N = 17), and Control (N = 23). The 36-item short-form survey (SF-36) was used to evaluate QoL pretest, posttest, and after a 3-month follow-up. The MCT was based on the practice of detached mindfulness, controlling rumination/anxiety, and challenging negative beliefs about symptoms. The PET was based on in-vivo and imaginal exposure to trauma-related events, and discontinuation of avoidance-oriented coping strategies. Both MCT and PET groups significantly improved QoL at posttest and follow-up, compared with the control group (P < .001); however, the MCT and PET groups showed no significant difference at posttest (P = .644) or follow-up (P = .646). Our results support the efficacy of PET as the standard for PTSD treatment, while also signifying the effectiveness of MCT at increasing the QoL in war-related PTSD at a 3-month follow-up.

Soldiers have high rates of substance use disorders (SUD), often in the aftermath of stressors experienced during military deployments. There are several factors that protect against SUD. For example, individual factors like perceived resilience and group factors such as unit cohesion may make someone less likely to abuse substances. However, there is little research on the differential influence of these resilience factors on SUD over and above deployment stressors. In this study, we examined the relative effects of perceived resilience, unit cohesion, and deployment stressors on SUD in a sample of 21,449 active duty and reserve soldiers from the U.S. Army (primarily White and male, mean age = 28.66, SD = 7.41) using structural equation modeling. We found that unit cohesion (ß = -.17) and perceived resilience (ß = -.16) had negative effects on SUD over and above deployment stressors. The study findings clarify research on resilience to SUD and have implications for addressing substance use in the military, specifically regarding the importance of building unit cohesion.

This study aims to contribute to an analysis of the well-being of military personnel who are deployed on humanitarian aid missions, taking their work-family (personal life) boundary management into consideration by analyzing the relationship between their preferences and enacted boundaries and military personnel' well-being. Specifically, this study analyzed the boundary fit approach, positing that it is the adjustment between individuals' preferences and enacted boundaries that influences their well-being. Using a sample of 327 military personnel, boundary management profiles were performed, considering the fit between their segmentation preferences and enactment. Furthermore, the relationship between these profiles and the military personnel' well-being was established. The results indicated that misfit profiles were found where the soldiers enacted less segmentation than desired or, on the contrary, more integration than desired, and a profile with a fit between the work-family segmentation they desired and enacted. The military personnel in the fit profile had significantly higher levels of well-being (i.e.,less exhaustion and more work engagement) than those in the misfit profile, who enacted less segmentation than desired. The findings have implications for the design of boundary management literature and future military missions.

The profound development that occurs during the first five years of a child's life may contribute to military families with young children facing unique challenges during reintegration. Yet, little is known about the reintegration experiences of military families with young children, and less so from the perspectives of non-deployed parents and families outside of the US. In this qualitative study, we explored the reintegration experiences of Australian Defense Force (ADF) families with young children (five years and younger). Through written responses to open-ended prompts, ADF service members (n = 9) and their non-deployed spouses (n = 38) reflected on periods of reintegration and discussed their family's adaption during this time. Using thematic analysis, six themes representing the reintegration experiences of these families were generated from the data. Four themes were generated from the combined experiences of service members and non-deployed parents, while a further two themes were generated from the experiences of non-deployed parents only. Relational and parenting challenges were at the forefront of reintegration experiences. These findings offer meaningful implications for practice and research to improve the quality of parent-child relationships and enhance outcomes for military families with young children during reintegration.

The concept of resilience is embedded within military culture and professional identity. To date, temporal changes in individuals' perceptions of their own resilience have not been systematically assessed in highstakes occupational contexts, like the military. The current study examined change in selfreported resilience over time by: (1) examining the longitudinal measurement invariance of the Brief Resilience Scale (BRS); (2) assessing the longitudinal pattern of resilience across a combat deployment cycle; and (3) examining predictors of postdeployment resilience and change in resilience scores across time. U.S. Army soldiers assigned to a combat brigade completed a survey at four time points over the course of a deployment cycle: (a) prior to deployment to Afghanistan; (b) during deployment; (c) immediately following return to home station; and (d) approximately 2-3 months thereafter. The longitudinal measurement invariance of the BRS was established. Growth curve modeling indicated that, on average, self-reported resilience decreased across the deployment cycle, but there was considerable individual variation in the rate of change. Of note, loneliness, as measured during deployment, predicted the rate of change in self-reported resilience over time. Results have implications for the longitudinal analysis of resilience and for the development of interventions with military personnel.

Active service members and Veterans with a combat-related traumatic brain injury (TBI) are four times more likely to attempt suicide than those without a TBI. TBIs are the signature injuries of the Post-9/11 conflicts and Combat Veterans (i.e., current and former service members who deployed in support of a combat mission) with these injuries are entitled to receive the Purple Heart medal. However, potentially tens of thousands of Combat Veterans did not receive, or were denied the Purple Heart during the first decade of the Global War on Terrorism because a TBI was not documented during the deployment. To our knowledge, this is the first study to explore the meaning of the Purple Heart and examine the impact of the Purple Heart on Army Combat Veterans with a combat-related TBI. Findings from this mixed methods study revealed that not receiving the Purple Heart is associated with increased suicide risk and lower quality of life after a brain injury. Additionally, thwarted belongingness, perceived burdensomeness, and perceived military institutional betrayal are associated with increased suicide risk in Army Combat Veterans with a TBI. This mixed methods study provides important insights into how Army culture is perceived and the power of the Purple Heart among this high-risk group of Combat Veterans.

Post-traumatic stress disorder (PTSD) and chronic low back pain (CLBP) are frequently co-morbid. Some research suggests that PTSD and CLBP may share common neurobiological mechanisms related to stress. Traditional biomedical education may be ineffective for PTSD and CLBP, especially when co-morbid. The purpose of this study is to determine if pain neuroscience education (PNE) is more effective than traditional education in reducing PTSD, disability, pain, and maladaptive beliefs in patients with CLBP. Participants with CLBP and possible PTSD/PTSD-symptoms were recruited for this study. Participants were randomly allocated to a PNE group or a traditional education group. The intervention included 30 minutes of education followed by a standardized exercise program once a week for 4-weeks with a 4 and 8-week follow-up and healthcare utilization assessed at 12-months. Forty-eight participants consented for this research study with 39 allocated to treatment (PNE n = 18, traditional n = 21). PNE participants were more likely to achieve a clinically meaningful reduction in PTSD symptoms and disability at short-term follow-up. At 12-months, the PNE group utilized healthcare with 76% lower costs. In participants with CLBP, PNE may reduce hypervigilance toward pain and improve PTSD symptoms. Participants who received PNE were more confident body-tissues were safe to exercise. These beliefs about pain could contribute to a decrease in perceived disability and healthcare consumption for CLBP.

Unit cohesion is the extent to which military service members feel committed to and supported by their military unit or, conversely, feel overlooked, neglected, and/or alienated. Unit cohesion reflects an important aspect of military social support and can act as a protective factor against mental health challenges, particularly in challenging situations. Theoretical suppositions and emerging evidence suggest that different types of unit support, specifically, vertical unit cohesion and horizontal unit cohesion, uniquely matter for service member well-being. Vertical unit cohesion (support from leaders in the unit and other higher-ranking positions) may be of universal importance to service members with implications for career progression and personal wellbeing, while horizontal unit cohesion (support from fellow unit members and peers) may be of importance under certain circumstances. Informed by the psychometric theory of scale development and validation, the dimensionality of unit cohesion theory, and the need for brief, sound measurement tools, this study first examined the psychometric properties of the Army STARRS four-item Vertical Unit Cohesion Scale in a longitudinal analysis with a large, diverse sample of Soldiers from the Pre/Post Deployment Study component of the Army STARRS dataset (N = 10,116). Then, exploratory analyses were conducted to examine the properties of the Horizontal Unit Cohesion Scale and understand the relationship between vertical and horizontal unit cohesion. Strong evidence for the Vertical Unit Cohesion Scale's psychometric soundness was established regarding factor structure, measurement invariance overtime, and construct validity. Conversely, preliminary evidence suggests that the three-item measure of Horizontal Unit Cohesion should be used with caution. Implications for researchers and military leadership are provided.

Stress occurs when conditions burden or exceed an individual's adaptive resources. Military personnel are often tasked with maintaining peak performance under such stressful conditions. Importantly, the effects of stress are nuanced and may vary as a function of individual traits and states. Recent interdisciplinary research has sought to model and identify such relationships. In two previously reported efforts, Soldiers first completed a comprehensive battery of trait assessments across four general domains thought to be predictive of performance: cognitive, health, physical, and social-emotional, and then completed the Decision-Making under Uncertainty and Stress (DeMUS) virtual reality task that probed spatial cognition, memory, and decision-making under stress and variable uncertainty. The present analysis explores whether cognitive, health, physical, and social-emotional trait assessments, as well as physiological state measures, predict or modulate DeMUS performance outcomes under stress. Multiple regression analyses examined the effect of each trait predictor and stress responsiveness on quantitative task performance outcomes. Results revealed that one measure of state stress reactivity, salivary cortisol, predicted lower recognition memory sensitivity. Further, trait measures of healthy eating, agility, flexibility, cognitive updating, and positive emotion predicted enhanced spatial orienting and decision-making performance and confidence. Together, the results suggest that select individual states and traits may predict cognition under stress. Future research should expand to ecologically relevant military stressors during training and operations.

Mental health officers (MHO) in the military often encounter soldiers expressing distress, manifested in threats and attempts at self-harm and suicide. While these behaviors are a significant stressor for therapists, they may also be an opportunity for posttraumatic growth (PTG). We aimed to examine whether the relatively frequent exposure of MHO to soldiers who report thoughts, intentions, and attempts at self-harm and suicide is related to their PTG, as well as tested the contribution of cognitive variables (the centrality of the event and the challenge to core beliefs), and a trait not previously considered in this context, i.e. self-compassion to PTG. Self-report questionnaires were completed by130 Israeli army MHO. Of these, 98.5% reported that they are exposed to self-harm. The questionnaires were collected between the years 2020-2021. The findings show a positive linear relationship, as well as a curvilinear relationship, between PTG and exposure to expressions of self-harm and suicide, the centrality of the event, and the challenge to core beliefs. In addition, self-compassion served as a moderator in the association between exposure and PTG. The study validates the PTG model in a population that has not previously been studied in this context, and may lead to a broader understanding of PTG in this context. They may help in designing dedicated training programs for therapists dealing with reports of self-harm and suicidal behavior.
