Using a sample of 289 Iraq/Afghanistan veterans, this study examined the contributions of combat exposure, agency, perceived threat, and guilt to posttraumatic stress disorder (PTSD) symptoms. Regression analyses indicated the four variables (together with demographic variables) accounted for 79% of the variance in PTSD symptoms. Guilt was the most important predictor. In addition, guilt mediated between exposure and PTSD symptoms, perceived threat and PTSD symptoms, and agency and PTSD symptoms. Implications of these findings are discussed. 相似文献

We report here for the first time the development of ‘age-hardened/toughened’ ceramic alloy based on MgO in the bulk polycrystalline form. This route allows for the facile development of a ‘near-ideal’ microstructure characterized by the presence of nanosized and uniformly dispersed second-phase particles (MgFe2O4) within the matrix grains, as well as along the matrix grain boundaries, in a controlled manner. Furthermore, the intragranular second-phase particles are rendered coherent with the matrix (MgO). Development of such microstructural features for two-phase bulk polycrystalline ceramics is extremely challenging following the powder metallurgical route usually adopted for the development of bulk ceramic nanocomposites. Furthermore, unlike for the case of ceramic nanocomposites, the route adopted here does not necessitate the usage of nano-powder, pressure/electric field-assisted sintering techniques and inert/reducing atmosphere. The as-developed bulk polycrystalline MgO–MgFe2O4 alloys possess considerably improved hardness (by ~52%) and indentation toughness (by ~35%), as compared to phase pure MgO. 相似文献

Previous research converges on demonstrating that benevolent sexism (BS) is socially approved, whereas hostile sexism (HS) is socially disapproved. We postulated that a sample of married women would be likely to report that their husbands express hostile sexist attitudes and engage in related actions towards them more in private than public contexts, where they lie concealed from public censure. By contrast, the women would report that their husbands would be likely to express benevolent sexist attitudes and engage in related actions more in public than private contexts, where they are reinforced not only by their target (i.e. wife), but also by significant others and the society at large. We tested these hypotheses with a sample of Black, heterosexually married Zimbabwean women (n = 109, mean age = 31.83). Results supported our hypotheses: the women reported hostile sexist attitudes and actions to be more likely to occur in private than public contexts; on the other hand, they reported benevolent sexist attitudes and actions to be more likely in public than private contexts. We conclude that differences in social approval of BS and HS account for these results. 相似文献

The acceptability and preference of psychological treatments is important in understanding patient treatment seeking, choice, engagement and attrition and possibly treatment response in health care. The acceptability of, and preference for, 14 different types of psychological treatment for posttraumatic stress disorder (PTSD) were investigated in a student population through invitation to participate in a web-based survey. Respondents were asked to rate each treatment on 10 scales and to rank the treatments in order of preference. Respondents were also asked whether they would seek treatment themselves, recommend treatment to friends and family, feel stigmatised by suffering from PTSD, had any prior knowledge of the treatments and if this had been positive or negative and whether they had a history of psychological problems or treatment. A total of 330 respondents completed the survey. A past or current history of psychological problems and treatment was surprisingly high. Almost all respondents indicated that they would seek or recommend treatment in spite of high levels of stigmatisation. Factor analysis of the 10 scales indicated two factors: Endorsement and Discomfort. Rank ordering on preference and Endorsement scores was highly consistent. The highly preferred and endorsed treatments involved cognitive therapy, exposure or psycho-education in spite of high levels of discomfort anticipated with exposure. Treatments involving new technologies, EMDR and psychodynamic psychotherapy received the lowest Endorsement and preference. There was a modest influence of prior knowledge of a treatment. 相似文献

The current study investigated a behavior-analytic treatment, functional analytic psychotherapy (FAP), for outpatient depression utilizing two single-subject A/A+B designs. The baseline condition was cognitive behavioral therapy. Results demonstrated treatment success in 1 client after the addition of FAP and treatment failure in the 2nd. This study highlights the challenges in measuring treatment progress and outcome idiographically in this population. 相似文献

The possible benefits of difficulty: how stress can increase and decrease subjective well-being 总被引:1,自引:0,他引:1
This study explores the effects of stress, trauma, coping and growth orientation on subjective well-being. Based on cognitive stress theory, it was hypothesized that adversity may contribute to increased or decreased well-being, depending on the subsequent meaning these experiences are given. Survey data from Norwegian UN/NATO veterans (N= 142) showed that stress and well-being were negatively associated (r=-0.20, p < 0.05) at the level of zero-order correlations. However, a full structural equation model revealed that the effect of stress on well-being was mediated positively through a problem-focused coping process combined with a growth component. Stress was negatively mediated through an avoidant-focused coping process and a distress component. The effect from stress was fully mediated in the model. The hypothesis that stress can produce both increased and decreased subjective well-being was confirmed. 相似文献

It is currently estimated that up to 40% of Aboriginal youth (aged 13–17) will experience some form of mental health problem within their lifetime. Of greater concern is the evidence that indicates that Aboriginal youth fail to access mental health services commensurate with this need. This is due, in part, to the characteristically monocultural nature of service delivery of existing services. This paper overviews a model that has been developed specifically for the engagement of Aboriginal youth (aged 13–17 years) in mental health settings. Importantly, a mix of urban (N = 43) and rural (N = 68) Aboriginal youth were represented within the sample to determine its efficacy across different language and tribal groups. The model proved to be effective in engaging 97% of Aboriginal youth (n = 108), with only a small number not effectively engaged (n = 3). The model provides a foundation for the further development of evidence‐based models of best practice that have so far provided to be elusive within this complex field. 相似文献

Breslau, Peterson, and Shultz (2008) reported that prior trauma alone, in the absence of PTSD, did not predict an increased PTSD risk, relative to no prior trauma. Only prior trauma that resulted in PTSD predicted an increased PTSD risk following a subsequent trauma. Recently, Cougle, Resnick, and Kilpatrick (2009) proposed that the effect of prior trauma might vary by type of prior trauma, a possibility not considered in Breslau et al. They report that childhood sexual or physical assault, in the absence of PTSD, increased the PTSD risk following a subsequent trauma. This report examines the PTSD effects of prior assaultive violence, using data from Breslau et al. (1998). The study assessed PTSD in relation to up to three events. Analysis was performed on the subset with PTSD assessment for two distinct events, the earliest trauma and a subsequent trauma (n = 967), using as reference persons with no prior trauma (n = 972). Neither prior assaultive violence nor other prior traumas, in the absence of PTSD, influenced the subsequent risk of PTSD. In contrast, prior PTSD increased considerably the PTSD risk of a subsequent trauma. The limitations in Cougle et al. (2009) and in this study and future research directions are discussed. 相似文献

Cognitive-behavioral theory suggests that social phobia is maintained, in part, by overestimates of the probability and cost of negative social events. Indeed, empirically supported cognitive-behavioral treatments directly target these cognitive biases through the use of in vivo exposure or behavioral experiments. While cognitive-behavioral theories and treatment protocols emphasize the importance of targeting probability and cost biases in the reduction of social anxiety, few studies have examined specific techniques for reducing probability and cost bias, and thus the relative efficacy of exposure to the probability versus cost of negative social events is unknown. In the present study, 37 undergraduates with high public speaking anxiety were randomly assigned to a single-session intervention designed to reduce either the perceived probability or the perceived cost of negative outcomes associated with public speaking. Compared to participants in the probability treatment condition, those in the cost treatment condition demonstrated significantly greater improvement on measures of public speaking anxiety and cost estimates for negative social events. The superior efficacy of the cost treatment condition was mediated by greater treatment-related changes in social cost estimates. The clinical implications of these findings are discussed. 相似文献
