Cognitive-behavioral coping strategies associated with combat-related PTSD in treatment-seeking OEF-OIF Veterans.

Posttraumatic stress disorder (PTSD) is associated with intrusive trauma-related thoughts and avoidance behaviors that contribute to its severity and chronicity. This study examined thought control and avoidance coping strategies associated with both a probable diagnosis and symptom severity of combat-related PTSD in a sample of 167 treatment-seeking Operations Enduring Freedom and Iraqi Freedom (OEF-OIF) Veterans. Within one year of returning from deployment, Veterans completed a survey containing measures of combat exposure, coping strategies, psychopathology, and postdeployment social support. Veterans with a positive screen for PTSD scored higher than Veterans without a positive screen for PTSD on measures of worry, self-punishment, social control, behavioral distraction, and avoidance coping strategies. Worry and social avoidance coping were positively related to PTSD symptoms, and greater perceptions of understanding from others were negatively related to these symptoms. A structural equation model revealed that scores on a measure of postdeployment social support were negatively associated with scores on measures of maladaptive cognitive coping (i.e., worry, self-punishment) and avoidance coping (social and non-social avoidance coping) strategies, which were positively associated with combat-related PTSD symptoms. These results suggest that maladaptive thought control and avoidance coping may partially mediate the relation between postdeployment social support and combat-related PTSD symptoms in treatment-seeking OEF-OIF Veterans. Consistent with cognitive therapy models, these findings suggest that interventions that target maladaptive coping strategies such as worry, self-punishment, and social avoidance, and that bolster social support, most notably understanding from others, may help reduce combat-related PTSD symptoms in this population.

Suicidal ideation in treatment-seeking Veterans of Operations Enduring Freedom and Iraqi Freedom: the role of coping strategies, resilience, and social support.

Recent epidemiologic studies have found an increased risk of suicide among Veterans of Operations Enduring Freedom and Iraqi Freedom (OEF-OIF) with psychiatric disorders. However, little is known about whether variables other than psychiatric conditions, such as coping strategies, resilience, and social support, may be related to suicidality in this population. A total of 167 OEF-OIF Veterans seeking behavioral or primary care services completed a survey containing measures of combat exposure, psychopathology, pain, psychological resilience, social support, and cognitive coping strategies. Thirty-six respondents (21.6%) reported contemplating suicide in the two weeks prior to completing the survey. Compared to suicide non-contemplators, suicide contemplators were older, and more likely to screen positive for depression and posttraumatic stress disorder (PTSD), and to report a deployment-related pain condition or complaint. They also scored higher on measures of worry, self-punishment, and cognitive-behavioral avoidance strategies, and lower on measures of psychological resilience and postdeployment social support. Multivariate analysis revealed that a positive depression screen, and higher scores on measures of self-punishment and cognitive-social avoidance coping were positively associated with suicidal ideation, while higher scores on measures of psychological resilience (i.e., positive acceptance of change) were negatively related to suicidal ideation. Moderator analysis revealed that a positive screen for depression or PTSD significantly diminished the protective effect of postdeployment social support on suicidal ideation. 1 in 5 treatment-seeking OEF-OIF Veterans may contemplate suicide. Interventions to reduce depressive symptoms, and maladaptive cognitive-behavioral coping strategies of self-punishment and cognitive social avoidance, and to bolster psychological resilience may help mitigate suicidality in this population.

Structure of posttraumatic stress disorder symptoms and psychosocial functioning in Veterans of Operations Enduring Freedom and Iraqi Freedom.

Posttraumatic stress disorder (PTSD) is one of the most prevalent psychiatric conditions in Veterans of Operations Enduring Freedom and Iraqi Freedom (OEF-OIF), but little is known about the structure of PTSD symptoms, and associations between PTSD symptom clusters and psychosocial functioning in this population. A total of 272 OEF-OIF Veterans in Connecticut completed a mail survey containing measures of psychopathology, resilience, and psychosocial functioning. Confirmatory factor analyses revealed that the 4-factor dysphoria model, which is comprised of separate re-experiencing, avoidance, dysphoria, and hyperarousal symptom clusters, provided the best representation of PTSD symptom structure in this sample. Dysphoria symptoms were independently associated with a broad range of psychosocial measures, even after controlling for age, combat exposure, and other PTSD symptom clusters. Re-experiencing symptoms were associated with alcohol use problems, and avoidance symptoms were associated with increased psychosocial difficulties and decreased perceptions of postdeployment social support. These results suggest that dysphoria symptoms were strongly related to a broad range of psychosocial measures in this sample of OEF-OIF Veterans. Dysphoria symptoms may deserve special attention in the assessment and treatment of symptomatic OEF-OIF Veterans.

Psychological resilience and postdeployment social support protect against traumatic stress and depressive symptoms in soldiers returning from Operations Enduring Freedom and Iraqi Freedom.

A number of studies have examined the prevalence and correlates of posttraumatic stress disorder (PTSD), depression, and related psychiatric conditions in soldiers returning from Operations Enduring Freedom and Iraqi Freedom (OEF/OIF), but none have examined whether factors such as psychological resilience and social support may protect against these conditions in this population. A total of 272 predominantly older reserve/National Guard OEF/OIF veterans completed a mail survey assessing traumatic stress and depressive symptoms, resilience, and social support. Resilience scores in the full sample were comparable to those observed in civilian outpatient primary-care patients. Respondents with PTSD, however, scored significantly lower on this measure and on measures of unit support and postdeployment social support. A hierarchical regression analysis in the full sample suggested that resilience (specifically, increased personal control and positive acceptance of change) and postdeployment social support were negatively associated with traumatic stress and depressive symptoms, even after adjusting for demographic characteristics and combat exposure. These results suggest that interventions to bolster psychological resilience and postdeployment social support may help reduce the severity of traumatic stress and depressive symptoms in OEF/OIF veterans.

An examination of the relation between combat experiences and combat-related posttraumatic stress disorder in a sample of Connecticut OEF-OIF Veterans.

Combat exposure is an important risk factor for posttraumatic stress disorder (PTSD). However, little research has examined specific combat experiences associated with PTSD and confirmatory factor analytically (CFA)-derived re-experiencing, avoidance, dysphoria, and hyperarousal symptom clusters. A total of 285 predominantly older National Guard/Reservist OEF-OIF Veterans completed an anonymous mail survey that assessed demographics and deployment history, a broad range of combat experiences, PTSD, and unit and postdeployment social support. Personally witnessing someone from one's unit or an ally unit being seriously wounded or killed (β = 0.22), and being exposed to "friendly" fire (β = 0.14) and land mines/traps (β = 0.13) were the only three combat experiences associated with severity of combat-related PTSD symptoms, after adjustment for age, relationship status, unit support, postdeployment social support, and other combat experiences. Differential patterns of associations were observed for specific combat experiences in relation to CFA-derived symptom clusters (e.g., experiencing "friendly" fire was associated with re-experiencing and dysphoria symptoms, but not avoidance and hyperarousal symptoms). Personally witnessing someone from one's unit or an ally unit being seriously wounded or killed (odds ratio [OR] = 4.34; 95% confidence interval [CI] = 1.62-11.61) and being exposed to "friendly" fire (OR = 2.94; 95%CI = 1.16-7.47) emerged as independent predictors of a positive screen for probable PTSD. Results of this study suggest that witnessing someone in one's unit or ally unit being seriously wounded or killed while in a combat zone and being exposed to "friendly" fire are most strongly associated with combat-related PTSD in this sample of OEF/OIF Veterans. Examination of the relation between specific combat experiences and combat-related PTSD in OEF/OIF Veterans may help inform etiologic models of PTSD, and guide prevention and treatment approaches in this population.
