急性心理性应激对自我参照记忆的影响

已有研究表明急性心理性应激会导致个体的自传体记忆受损,然而急性心理性应激如何影响个体加工当前的自我相关信息,还没有研究结论,本研究旨在丰富和拓展这一领域的研究,从而更加全面深入的了解急性心理性应激对自我相关信息的影响。本研究将自我参照记忆的R/K(记得/知道)范式与特里尔社会应激测试(Trier Social Stress Test:TSST)相结合,考察59名处在不同急性心理性应激状态下的被试自我参照记忆的成绩。结果发现高应激反应组自我参照的R回忆率值显著低于低应激反应组,研究结果发现,被试在特里尔社会应激测试过程中的急性心理性应激反应越强,自我参照的R回忆率越低。结果表明急性心理性应激会抑制个体对当前自我相关信息的加工,削弱了自我参照记忆。     

Coping Style Following Acute Stress in Competitive Sport

Abstract

The purpose of this study was to ascertain coping styles among competitive athletes in response to various acute stressors. Specifically, the authors used a 134-item survey to measure approach and avoidance coping styles, with task-focused and emotion-focused coping tendencies nested hierarchically as subdimensions under each. Australian and U.S. college-aged participants indicated the extent to which they used approach, avoidance, task-focused, and emotion-focused coping strategies (a 4-factor model) in response to selected acute stressors experienced during sport competition. The authors computed confirmatory factor analysis to test the theoretically driven model. The criterion loading of .30 and above for each of the factors reduced the survey to 65 items. Findings indicated stronger links between the 2 approach constructs of task- and emotion-focused coping than between the 2 avoidance constructs of those subdimensions. The goodness-of-fit indices for the 4-factor model were 0.58 and 0.57 for Australian and U.S. samples, respectively, and .71 overall. Concomitant low correlations between the 2 approach (0.18) and the 2 avoidance dimensions (0.43) reflected relatively high residuals between stressors. In general, psychometric analyses suggest that coping style may be more prevalent in some situations than others, lending partial support for the transactional model of coping.     

慢性阻塞性肺疾病急性加重期临床路径应用效果评价

评价临床路径管理在慢性阻塞性肺疾病急性加重期（AECOPD）的应用效果。通过采用回顾性调查,比较进入临床路径（路径组）和没有进入临床路径（对照组）两组患者在住院费用、住院时间及治疗效果3项指标上的差别。结果显示实施临床路径患者（路径组）的平均住院费用、平均住院日等指标均有不同程度的下降,而治愈率有所上升。从而得出临床路径在AECOPD病种的应用能够规范医疗行为,提高医疗护理质量的结论。     

真实急病情境下共情对大学生慈善捐助的影响:有调节的中介效应

基于真实急病情境,采用道德强度、道德认同、共情和慈善捐助问卷对462名大学生进行调查,探讨了共情影响大学生慈善捐助的内在机制。结果显示:(1)女生在真实急病情境下比男生更容易对主人公的不幸事件产生共情反应;大学生真实急病情境下的共情反应随年级关系的疏远而逐渐降低;(2)共情在道德强度与慈善捐助的关系中具有部分中介作用,即道德强度通过共情对慈善捐助产生间接影响;(3)道德认同对共情的中介作用具有调节效应,具体而言,相对于低道德认同的个体,高道德认同的个体表现出更多的慈善捐助,并且共情对道德强度和慈善捐助的中介效应也显著增强。研究结论对于理解慈善捐助的内在机制具有理论价值,对于慈善捐助的教育和干预具有现实启示意义。     

对外科急腹症诊疗中伦理学矛盾的探讨

由于外科急腹症的特殊性,产生了与其他科室不同的伦理学矛盾。本文探讨了急腹症诊疗中存在的伦理学矛盾和相应对策。在急腹症诊疗过程中,要重视伦理学矛盾产生的原因,完善急腹症诊疗中存在的流程问题,自觉实践医学伦理学的知情同意原则,有助于化解医患矛盾,减少医疗纠纷;同时也要减轻医生工作压力,加强团队合作精神。     

直立位机械通气可行性的探讨

机械通气是治疗急性肺损伤／急性呼吸窘迫综合征（ALI／ARDS）的重要措施之一,本文从理论上探讨直立位机械通气的可行性,推测其可能的机制,与肺保护通气策略的关系,尚需要解决的问题,以期证明优于传统机械通气方式。     

急性心理性应激诱发的神经内分泌反应及其影响因素

急性心理性应激源分别通过下丘脑-脑垂体-肾上腺轴(hypothalamus–pituitary–adrenal axis,HPAA)和交感神经-肾上腺髓质轴(sympathetic-adrenal medulla axis)诱发神经内分泌反应。唾液皮质醇被认为是检测急性心理性应激所诱发的HPA轴反应的稳定指标。以特里尔社会应激测试(Trier Social Stress Test,TSST)及其变式作为应激源, 以HPA轴的反应作为应激指标, 影响个体在急性心理性应激情境中发生特异性神经内分泌反应的因素主要包括人口统计学、环境和应激频率三大方面, 未来应加强急性心理性应激所诱发的神经内分泌反应的纵向研究。

Optimism across cultures: In response to the severe acute respiratory syndrome outbreak

Based on our early research, we predicted that the Chinese may be more optimistic and less pessimistic than North Americans in response to negative life events. A survey was conducted to investigate optimism cross culturally in the context of the severe acute respiratory syndrome (SARS) outbreaks in Canada and China. Chinese students in Beijing and European Canadians in Toronto answered questions about their perceptions of SARS. No significant cultural difference was found on dispositional optimism, as measured by the Revised Life Orientation Test (LOT-R). Unrealistic optimism was measured in the context of SARS. Both groups demonstrated unrealistic optimism (i.e. reporting that the self was less likely than an average person to get infected with SARS). Such optimistic bias was stronger among Chinese than among Canadians. Compared to the actual infection rates in Beijing and Toronto, both Chinese and Canadian participants overestimated their own chances of getting infected, indicating that they were being pessimistic. Indeed, Chinese were less pessimistic than Canadians. In addition, even though the Chinese reported more inconvenience brought by SARS than did Canadians, they also reported more positive changes brought by SARS, reflecting the Chinese dialectical views of events. Implications for research on optimism in context are discussed.     

The psychology behind the masks: Psychological responses to the severe acute respiratory syndrome outbreak in different regions

Severe acute respiratory syndrome (SARS) was first reported in China, and spread to 29 regions, affecting over 8000 people worldwide. For the general public, the psychological impact of SARS may have been greater than the physical health danger of the disease. The present paper proposes the influence of psychological factors on people's cognitive, affective, and behavioral responses during the SARS outbreak. The various papers in this special issue of the Journal reveal how people have reacted during the SARS outbreak: People's general coping styles may be related to their health behavior during the outbreak. Cultural differences were evident in the perception of SARS, and individuals' perceptual styles may have influenced their ability to cope with the outbreak. The way in which individuals coped with SARS-related stressful events was different from their usual practices of managing daily stress. Individual differences in the adoption of preventive measures were related to the distinct susceptibility to several social-cognitive biases.
