perceived burden in spouses of national guard Reserve Service members deployed during operations enduring and iraqi freedom
Journal of Anxiety Disorders, 2011Co-Authors: Catherine M Caska, Keith D RenshawAbstract:Abstract Spouses of combat veterans with posttraumatic stress disorder (PTSD) experience elevated psychological distress. Recent research indicates that spouses’ perceptions of burden may be one mechanism of such distress, but there are several gaps in this literature. No research has examined perceived burden in relation to symptoms other than PTSD or subclinical levels of psychological distress, and very little research has focused on characteristics of spouses that may be related to their perceptions of burden. The current study examined these variables in 130 spouses of Reserve component troops deployed during Operations Enduring/Iraqi Freedom. Spouses’ burden was positively associated with symptoms of PTSD, depression, and anxiety in Service members, regardless of clinical severity. Moreover, burden fully mediated the relation between each type of symptom and spouses’ own psychological distress. Furthermore, levels of burden were significantly related to spouses’ neuroticism, avoidant coping, and self-efficacy, but only avoidant coping remained a significant predictor of burden when accounting for Service members’ distress. These results suggest that a broad range of Service members’ symptoms are related to spouses’ burden and distress, and although individual characteristics of spouses may be related to their perceptions of burden, Service members’ symptoms play a primary role.

associations of coping processes with posttraumatic stress disorder symptoms in national guard Reserve Service members deployed during the oef oif era
Journal of Anxiety Disorders, 2010Co-Authors: Camila S Rodrigues, Keith D RenshawAbstract:Studies have identified coping processes as one potential factor influencing PTSD in veterans. This study examined the associations between coping, combat exposure, and PTSD among 218 National Guard veterans deployed overseas since 2001. Problem-focused coping was unrelated to combat exposure and PTSD symptoms. In contrast, increased levels of emotion focused coping (EFC) were found in veterans who reported higher levels of combat exposure. Moreover, the severity of combat was a curvilinear moderator of the relation between coping process and PTSD, such that EFC was unrelated to PTSD symptom severity at low levels of combat, associated with higher symptom severity at moderate levels of combat, and associated with lower symptom severity at high levels of combat. These findings indicate that the type and severity of trauma may moderate the association of coping and psychological outcomes, and that these associations might not be linear.

bidding strategy of virtual power plant for participating in energy and spinning Reserve markets part ii numerical analysis
IEEE Transactions on Power Systems, 2011Co-Authors: Elaheh Mashhour, S M MoghaddastafreshiAbstract:This paper is to evaluate the presented model in part I for bidding strategy of virtual power plant (VPP) with centralized control in a joint market of energy and spinning Reserve Service. Two test VPPs are introduced and different scenarios are considered for markets prices. At first, the participation of VPP in only energy market is studied. Then, the spinning Reserve market is taken into consideration and the bids of VPP in a joint market of energy and spinning Reserve Service is studied under different scenarios of markets prices and the results are analyzed. In all cases, the results show the effectiveness and the quality of the procedure and validate the proposed model.

bidding strategy of virtual power plant for participating in energy and spinning Reserve markets part i problem formulation
IEEE Transactions on Power Systems, 2011Co-Authors: Elaheh Mashhour, S M MoghaddastafreshiAbstract:This paper addresses the bidding problem faced by a virtual power plant (VPP) in a joint market of energy and spinning Reserve Service. The proposed bidding strategy is a non-equilibrium model based on the deterministic price-based unit commitment (PBUC) which takes the supply-demand balancing constraint and security constraints of VPP itself into account. The presented model creates a single operating profile from a composite of the parameters characterizing each distributed energy resources (DER), which is a component of VPP, and incorporates network constraints into its description of the capabilities of the portfolio. The presented model is a nonlinear mixed-integer programming with inter-temporal constraints and solved by genetic algorithm (GA).

risk and protective factors for difficulty controlling violent behavior in national guard and Reserve Service members
Journal of Interpersonal Violence, 2017Co-Authors: Miranda E Worthen, Carol S Fullerton, Robert K Gifford, Sujit D Rathod, Robert J Ursano, Gregory H. Cohen, Laura Sampson, Sandro Galea, Jennifer AhernAbstract:Violent behavior is an important problem for military Service members and veterans. A representative cohort of U.S. Reserve and National Guard personnel (N = 1,293) were interviewed to assess self-reported problems controlling violent behavior, deployment traumas, posttraumatic stress disorder (PTSD), alcohol abuse, and social support. Poisson regression models were used to estimate the associations of violent behavior with risk and protective factors. Problems controlling violent behavior were uncommon among male (3.3%) and female (1.7%) Service members. Adjusted prevalence ratios (aPR) showed associations between violent behavior and deployment traumas (aPR = 1.67, 95% confidence interval [CI] = [1.34, 2.08]), PTSD (aPR = 9.95, 95% CI = [5.09, 19.48]), and PTSD symptom severity (aPR for each additional PTSD symptom = 1.07, 95% CI = [1.06, 1.09]). Social support was associated with lower prevalence of violent behavior (aPR = 0.62, 95% CI = [0.52, 0.76]). The association between violent behavior and alcoh...

anger problems and posttraumatic stress disorder in male and female national guard and Reserve Service members
Journal of Psychiatric Research, 2014Co-Authors: Miranda E Worthen, Carol S Fullerton, Robert K Gifford, Sujit D Rathod, Robert J Ursano, Gregory H. Cohen, Laura Sampson, Sandro Galea, Jennifer AhernAbstract:: Anger is a common problem among veterans and has been associated with posttraumatic stress disorder (PTSD). This study aimed to improve understanding of how anger and PTSD co-occur by examining gender differences and differences by whether the triggering traumatic event is deployment-related vs. civilian-related in current Service members. A representative cohort of Reserve and National Guard Service personnel (n = 1293) were interviewed to assess for deployment- or civilian-related traumas, PTSD, and anger. The prevalence of self-reported anger problems was estimated among male (n = 1036) and female (n = 257) Service members. Log Poisson regression models with robust standard errors were used to estimate the associations of problems with anger with PTSD and PTSD symptom severity for men and women. Self-reported anger problems were common among male (53.0%) and female (51.3%) Service members. Adjusted prevalence ratios (PR) showed associations between anger and PTSD connected to both civilian- and deployment-related traumas (PR were 1.77 (95% CI 1.52-2.05) and 1.85 (95% CI 1.62-2.12), respectively). PTSD symptom severity was also associated with anger. This study was cross-sectional and so a causal relationship between PTSD and anger cannot be established. Problems with anger are common among male and female current Guard and Reserve members. These findings suggest that anger treatment should be made available to current Service members and that clinicians should assess anger problems irrespective of gender. Future research should examine the effectiveness of anger treatment protocols by gender.
