Effects of live exposure on symptoms of posttraumatic stress disorder: the role of reduced behavioral avoidance in improvement 总被引:3,自引:0,他引:3
Although the effectiveness of cognitive-behavioral treatment in posttraumatic stress disorder (PTSD) is well established, few studies examined its effects on individual PTSD symptoms and possible mechanisms of improvement in symptoms. In a previous randomized controlled study [Ba?og lu, M., Salciog lu, E., Livanou, M., Kalender, D., & Acar, G. (2005). Single-session behavioral treatment of earthquake-related posttraumatic stress disorder: A randomized waitlist controlled trial. Journal of Traumatic Stress, 18, 1-11] a single session of behavioral treatment involving self-exposure instructions was highly effective in reducing earthquake-related PTSD. In the present study we examined the effects of treatment on each PTSD symptom and which symptoms improved early in treatment. Because the intervention focused solely on behavioral avoidance, we hypothesized that avoidance would be the first symptom to change and that reduction in avoidance would generalize to all other symptoms. The results showed significant between-groups treatment effect on only behavioral avoidance early in treatment (week 6). At 6 months post-treatment recovery rates ranged from 60% to 89% for 15 PTSD symptoms, including the numbing symptoms. Lack of improvement in avoidance was associated with lack of improvement in 12 symptoms. The critical process in recovery thus appeared to be increased sense of control associated with reduction in avoidance. These findings imply that live exposure to fear cues designed to enhance sense of control might be sufficient for recovery from PTSD. 相似文献

Individuals prefer to receive information that is consistent with their attitudes. Three experiments examined whether attitude strength moderates this selective exposure effect. Experiments 1A and 1B found that participants preferred attitudinally consistent information but that this effect was more pronounced to the extent that the attitude was strongly held. Experiment 2 replicated these findings and ruled out an alternative interpretation that a general tendency to hold strong attitudes rather than issue-specific attitude strength moderates selective exposure. Discussion concerns the implications of these findings and the possibility that other variables moderate the selective exposure effect. 相似文献

Abstract: The argument proceeds from a sense of imminent danger; 9/11 and its sequel challenge our deepest pretensions regarding the universality and self‐evidence of moral/political conviction. The intransigence of such convictions is now an important source of international conflict and terror. It also signifies that the resolution of the disorder that now confronts the international community requires a transformation in our conception of morality itself. In this regard, philosophy has an important task to address. The discussion explores a radical change in our understanding of just war, the distinction between war and peace, the logic of conflict, and similar topics. 相似文献

职业暴露是医务人员最常见的职业伤害,为探求有效的防护方法,对我院2005年至2008年报告的职业暴露进行了分析,结果发现医务人员职业暴露漏报严重,护士发生职业暴露最多(占57.4%),主要为针刺伤(占85.2%),暴露源以乙型肝炎为主(占53.2%)。应加强医务人员标准预防和职业安全知识的教育与培训,建立和健全职业暴露的监测体系。 相似文献

This study examined the relationships among exposure to terrorism, individual differences in adult attachment dimensions, perceived stress, and posttraumatic stress disorder (PTSD). A representative sample of 254 adults who had experienced more than 7 years of ongoing exposure (OGE) to rocket and mortar fire in southern Israel was compared to 308 individuals with no exposure (NE) to terrorism. OGE individuals reported significantly elevated levels of insecure attachment, perceived stress, and PTSD-symptoms as compared to the NE individuals. The associations between perceived stress and PTSD-symptoms were significantly stronger in the OGE group, compared to the NE group. For OGE individuals, the elevated level of perceived stress mediated the association between Attachment Anxiety and PTSD-symptoms. Theoretical and clinical implications of the findings are discussed. 相似文献

纯粹接触效应是指个体接触一个刺激的次数越频繁,个体对该刺激就越喜欢的现象。本文通过两个实验考察刺激的呈现次数与位置对纯粹接触效应的影响。实验1讨论了纯粹接触效应与刺激呈现次数之间的关系,发现刺激的偏好程度和再认成绩在不同的刺激呈现次数水平上都具有显著性差异。实验2讨论了纯粹接触效应与刺激呈现位置之间的关系,结果发现不同呈现位置上刺激的偏好程度不具有显著性差异,而再认成绩之间具有显著性差异。 相似文献

This study examined the role of media body comparison as a mediator of the relationships between psychological factors and sociocultural pressures to be thin and body dissatisfaction in both females and males. Participants were 1,386 females (mean age = 19.37 years) and 1,130 males (mean age = 19.46) from diverse backgrounds who completed a self-report questionnaire. Path analysis was used to test a cross-sectional model in which media body comparison mediated the impact of self-esteem, depressive mood, parent dieting environment, friend dieting, TV exposure, magazine message exposure, weight teasing and body mass index (BMI) on body dissatisfaction. In females, media body comparison partially or fully mediated relationships between self-esteem, depressive mood, friend dieting, magazine message exposure and BMI, and body dissatisfaction. In males, media body comparison was not a significant predictor of body dissatisfaction. This research particularly highlights the need to further examine processes that are involved in the development of body dissatisfaction in males. 相似文献

固定位置区域提示下视觉注意范围等级的ERP研究 总被引:10,自引:0,他引:10
研究视觉空间注意中注意范围的脑内时程的动态变化。被试为 14名青年人 ,使用固定位置的、3种不同直径的线圈作为注意范围的区域性提示 ,祛除空间定位因素的影响 ,记录反应时和事件相关电位 (ERP)数据。结果显示 :提示范围由小到中等时 ,反应时延长 ,而由中等到大范围时 ,反应时缩短 ;提示物和靶刺激诱发ERP的早成分 (N1、P1)不受提示范围大小的调节 ,而其P2、N2的波幅与潜伏期均明显受到提示范围大小的影响。这些结果说明 :①视觉注意诱发的P1、N1成分 ,主要与空间定位信息的加工相关 ;②提示物诱发的P2、N2成分与注意范围相关 ;③在视觉信息加工过程中 ,空间位置的信息要早于其它信息被加工 ,支持视觉信息串行加工观点 相似文献

家族企业高层管理者胜任特征模型 总被引:129,自引:0,他引:129
通过对18名家族企业高层管理者的关键行为事件访谈,建立了家族企业高层管理者胜任特征模型,初步结论是:(1)采用BEI关键事件访谈方法揭示高层管理者胜任特征模型,胜任特征的出现频次和平均等级是较为稳定的指标,最高等级分数受到了访谈长度的影响。研究还发现,胜任特征的平均等级、最高等级都能区分绩效优异和绩效一般的家族企业高层管理者。(2)我国家族企业高层管理者的胜任特征模型包括: 威权导向、主动性、捕捉机遇、信息寻求、组织意识、指挥、仁慈关怀、自我控制、自信、自主学习、影响他人等11项胜任特征。其中,与国外企业高层管理者通用胜任特征模型的9项相一致,与国有企业高层管理者的通用胜任特征模型的5项相一致。而威权导向、仁慈关怀是我国家族企业高层管理者独有的胜任特征。 相似文献
