Background: Recent evidence suggests that event centrality has a prominent association with post-traumatic stress disorder (PTSD) symptoms. However, evidence for this notion thus far has been mostly correlational. We report two studies that prospectively examined the relationship between event centrality and PTSD symptoms. Study 1 Methods: Participants (N?=?1438) reported their most stressful event (“prior event”), along with event centrality, PTSD symptoms, and neuroticism. At Time 2 participants reported their most stressful event since Time 1 (“critical event”), along with measures of event centrality and PTSD symptoms. Study 1 Results: Event centrality for the critical event predicted PTSD symptoms, after controlling for event centrality and PTSD symptoms of the prior event and neuroticism. Study 2 Methods: In the second study (N?=?161) we examined changes in event centrality and PTSD symptoms over a month. Study 2 Results: Using a cross-lagged panel design, results revealed event centrality at Time 1 significantly predicted PTSD symptoms at Time 2, but the reverse was not significant. Conclusions: In two studies, a prospective association between event centrality and PTSD symptoms, but not the reverse, emerged. This evidence implicates event centrality in the pathogenesis and/or maintenance of PTSD symptoms.  相似文献

Researchers have identified peritraumatic emotions as important predictors of who will develop posttraumatic stress disorder (PTSD) symptoms. However, such investigations have not examined full profiles of emotions, perhaps because of the typical emphasis on fear or other Criterion A2 emotions. Such an examination could help us identify which peritraumatic emotions are prominent, and how they relate to important posttrauma outcomes. Thus, the aim of this study was to identify distinct profiles of peritraumatic emotions and their correlates using a comprehensive survey of peri- and posttraumatic reactions. We conducted a latent profile analysis of peritraumatic emotions in 398 undergraduate students who reported a DSM–IV A1 trauma and then compared the resulting profiles on trauma type, PTSD, depression, and posttraumatic cognitions. Six distinct profiles emerged: 3 had consistently low, medium, or high levels across the range of emotions, with 3 others primarily characterized by low shame and guilt, high anger and guilt, and low guilt. These profiles significantly differed in terms of trauma type, PTSD, depression, and posttraumatic cognitions. In particular, profiles with high levels of anger, shame, and guilt were consistently related to overall worse functioning. Importantly, fear and associated emotions did not differentiate between profiles. These results have important implications for the phenomenology of posttrauma emotional reactions and strongly suggest that the clinical assessment of traumatic experiences go beyond fear-based conceptualizations.  相似文献

Traumatic events are highly prevalent in South African society and psychologists who work with survivors of trauma have been identified as particularly at risk of being adversely affected by their work, and experiencing vicarious trauma. This study aimed to explore the experiences of a group of South African psychologists who work predominantly with trauma survivors. Individual semi-structured interviews were conducted with six psychologists (females = 67%). The predominant type of trauma encountered by participants in clinical practice was interpersonal trauma in the form of physical and sexual abuse (83%). Data were analysed using thematic analysis. All participants reported symptoms of vicarious trauma including disruption in cognitive schemas, symptoms characteristic of post-traumatic stress disorder, and somatic symptoms. Participants also reported vicarious post-traumatic growth including an enhanced sense of interpersonal connectedness and positive changes in their philosophy of life and self-perceptions. The findings serve to sensitise psychologists to the impact of working with trauma survivors so as to enhance the efficiency of psychological service delivery to traumatised populations.  相似文献

Theories of posttraumatic stress disorder (PTSD) implicate emotional processes, including difficulties utilizing adaptive emotion regulation strategies, as critical to the etiology and maintenance of PTSD. Operation Iraqi Freedom, Operation Enduring Freedom, and Operation New Dawn (OIF/OEF/OND) veterans report high levels of combat exposure and PTSD. We aimed to extend findings suggesting that emotion regulation difficulties are a function of PTSD, rather than combat trauma exposure or common comorbidities, to OIF/OEF/OND veterans, in order to inform models of PTSD risk and recovery that can be applied to returning veterans. We tested differences in emotion regulation, measured with the Difficulties in Emotion Regulation Scale and Emotion Regulation Questionnaire, among trauma-exposed veterans with (n = 24) or without PTSD (n = 22) and healthy civilian comparison participants (n = 27) using multivariate analyses of covariance, adjusting for major depressive disorder, anxiety disorders, and demographic variables (age, sex, and ethnicity). Veterans with PTSD reported more use of expressive suppression and more difficulties with emotion regulation than veterans without PTSD and healthy comparison participants. Groups did not differ on cognitive reappraisal. Findings suggest the key role of PTSD above and beyond trauma exposure, depression, and anxiety in specific aspects of emotion dysregulation among OIF/OEF/OND veterans. Interventions that help veterans expand and diversify their emotion regulation skills may serve as helpful adjunctive treatments for PTSD among OIF/OEF/OND veterans.  相似文献

The current study extends knowledge regarding the differential impact of natural disasters among White, African American, and Latino survivors of Hurricane Ike through its use of a large, regional sample recruited via representative sampling procedures to examine the associations between cultural identification and disaster impact, including loss, damage, and negative mental health outcomes. Consistent with previous research, results indicated disparities between cultural groups with regard to disaster exposure. Additionally, type of disaster impact was differentially associated with PTSD and depression status dependent on cultural group. Specifically, the extent of personal disaster exposure, property damage, and loss of services made significant contributions to PTSD status among White survivors. African-Americans were more likely than White and Latino Ike survivors to endorse post-disaster PTSD and depression and endorsement of depression was predicted by severity of property damage. With respect to Latino respondents, only the extent of personal disaster exposure significantly contributed to both PTSD and depression status. Implications of the current findings are discussed with regard to future disaster preparedness and response efforts and the implementation and evaluation of community-based disaster resources.  相似文献

In a recent series of studies, it was demonstrated that originally neutral stimuli that were predictive of an electrocutaneous stimulus in a differential aversive conditioning procedure not only acquired “signal-value” but also acquired a negative affective valence. These affective changes were not only evident from the evaluative ratings scales, but also from the data of an affective priming procedure. This response-latency based priming procedure has recently been employed as an indirect and unobtrusive index of stimulus valence (attitudes) (e.g., Fazio, Jackson, Dunton, & Williams, 1995). In the present experiment, the use of the affective priming procedure as an indirect measure of stimulus valence was further explored. Results showed that aversively conditioned stimuli revealed their newly acquired valence in this priming procedure. As predicted, this effect was obtained at the short SOA (300 ms) but not at the long SOA (1000 ms). The significant SOA X Priming interaction suggests that the affective priming procedure is less or not affected by demand effects and (self-presentational) response strategies. This makes the affective priming effect and excellent and unobtrusive measure of affective valence and an interesting alternative to subjective rating scales in situations where demand effects might otherwise influence responding. The results are also related to recent research on conditioning models of the acquisition of anxiety disorders, and to research on the co-occurrence of expectancy learning and affective learning within these models.  相似文献

Attentional interference by threat is associated with PTSD, but the mechanisms of this relationship remain unclear. Attentional interference might be related to increased use of maladaptive thought control strategies, such as suppressing unwanted thoughts (thought suppression) or replacing threatening thoughts with everyday concerns (worry), which increase PTSD risk. Conversely, attentional interference might be associated with reduced use of adaptive strategies, such as talking about threatening thoughts (social control), which decrease PTSD risk. This study tested if thought control strategies mediate the relationship between attentional interference and PTSD. Sixty-one male Vietnam-era veterans completed measures of PTSD symptoms and thought control strategies. Participants also completed a Visual Search Task measuring attentional interference, which required participants to identify a target letter string among a group of threat or neutral words. Attentional interference by threat was related to PTSD symptoms, and mediation analyses revealed significant indirect effects of attentional interference through thought suppression and worry. Attentional interference was related to re-experiencing and avoidance, but not hyperarousal, symptom clusters. Thought suppression was a unique mediator for re-experiencing, whereas thought suppression and worry both mediated the relationship with avoidance. These results offer evidence for maladaptive thought control strategies as a mechanism linking attentional biases for threat to PTSD.  相似文献

Extant military studies show that stigma has a variable association with seeking mental health treatment and mental health distress. Previous studies used a general measure of stigma that does not differentiate between stigma source or type. Stigma source can be either self-perceived or perceived from others, and stigma type can include stigma for disorder or stigma for help-seeking. Civilian literature demonstrates that self-stigma is more detrimental to individual functioning than stigma perceived from others, and prior studies in National Guard service members (NGSMs) show that self-stigma and stigma perceived from unit leaders were associated with lower help-seeking intentions relative to stigma perceived from unit members or family members. No military study has simultaneously explored the associations of demographic and distress variables with various stigma types and sources. To determine if prior mixed findings were due to the use of a general measure of stigma, NGSMs (n = 163) completed demographic and distress measures, as well as stigma source (e.g., self, leader) and type (i.e., general, disorder, help-seeking) assessments. General stigma was positively associated with all stigma types and sources as well as a college education. Disorder stigma was positively associated with stigma from nonmilitary sources, and self-stigma for help-seeking was negatively associated with help-seeking intentions. Likelihood of deploying again was positively associated with disorder and help-seeking stigma when perceived from someone in authority. Given the unique associations observed, future studies should utilize specific measures of stigma when examining factors related to postdeployment functioning.  相似文献

Anger and aggression are common combat-related behavioral health problems. The impact of combat on anger and aggression appears to be largely attributable to symptoms of posttraumatic stress disorder (PTSD). Factors that moderate the purported pathway from combat to anger and aggression are poorly understood. We examined the conditional direct and indirect associations of combat exposure with self-reported anger and aggression using survey data collected from 592 U.S. Soldiers during a combat deployment in Afghanistan. Unit morale was examined as a moderator between combat exposure and PSTD symptoms, as well as the indirect association of combat exposure with anger and aggression via PTSD symptoms, controlling for depression symptoms. Results indicated that unit morale was negatively correlated with PTSD symptoms and self-reported anger and aggressive behaviors. Perceptions of unit morale moderated the direct association of combat exposure with PTSD symptoms. Unit morale also moderated the indirect association of combat exposure with anger and aggression through PTSD symptoms. Unit morale moderated the association of combat exposure with anger and aggression during combat operations by putatively mitigating the deleterious effect of combat on stress-related symptoms. The impact of policy and leadership on soldier and unit morale should be carefully considered given its protective role during combat operations.  相似文献

Distress tolerance (DT), the perceived or actual ability to tolerate negative emotional or physical states, is inversely related to posttraumatic stress disorder (PTSD) symptoms in civilian, community samples. No studies to date have examined the relationship between DT and PTSD in clinical samples of veterans with a comorbid diagnosis of PTSD and a substance use disorder (SUD). Thus, the present study examined the relationship between DT and PTSD in a sample of predominately African American, male veterans (n = 75) diagnosed with comorbid PTSD and SUD (according to a structured clinical interview). Results of hierarchical linear regression models indicated that DT was inversely related to total PTSD symptom severity score, above and beyond depressive symptoms and SUD severity. Of the 4 symptom clusters, DT was inversely associated with intrusions and hyperarousal. These findings are discussed in light of previous work with civilian samples. Determining whether treatment incorporating DT skills would be useful for veterans undergoing PTSD treatment should be evaluated.  相似文献
