工作负载的测量和评定

长期处于应激状态而又适应不良者可导致疾病。人类经常遇到的心理、社会性应激源除了生活事件以外,长期工作负载过重也是其中之一。本文通过对24名在监护病房工作的护士的工作负载的测量介绍了在西方国家常用的工作负载的测量和评定方法。     

社会应激对成年后进行群体隔离的大白鼠的行为的影响

本文观察了在成年后进行群体隔离的大白鼠与群居鼠在摄食、饮水、睡眠等方面的行为差异。着重观察了社会应激对成年后进行群体隔离的动物的行为的影响,以研究群体隔离时动物的年龄与过去生活经验是不是动物在社会应激时发生的行为改变的关键因素。 结果表明:群居与隔离两种环境对动物摄食、饮水和体重无明显影响,但隔离动物睡眠时间较群居动物短。即使在成年后进行群体隔离、社会应激对隔离动物的摄食、饮水、睡眠和攻击性行为的影响也比群居组明显。但进行群体隔离时动物的年龄和隔离前有较长时间的群居生活经验可大大减轻社会应激时行为反应的强度,也可使适应过程发生得快些。这说明早期环境和过去生活经验的重要性。社会应激影响饮水和摄食的方式随年龄而改变,年龄较大的群居鼠对社会应激的适应可能比年龄较轻的群居鼠差。     

秒回?信息通讯技术时代的职场通讯压力

职场通讯压力是指员工想要快速回复基于信息通讯技术(information and communication technology, ICT)的工作消息而体验到的紧迫性, 现有研究对其成因及影响路径的探讨较为零散且缺乏系统性认识。基于工作要求-资源模型并结合努力-恢复模型, 讨论作为工作要求的ICT使用以及作为个人要求/资源的个体因素对职场通讯压力的前因作用; 探讨职场通讯压力因阻碍恢复活动而对员工身心健康以及工作和家庭领域产生的消极影响, 以期增进对职场通讯压力的全面了解, 丰富现有研究对ICT使用后果的认识, 并为未来研究的展开以及员工职业心理健康干预实践提供参考。     

人格类型对应激反应影响的实验研究(实验室应激源部分)

本研究以EPQ为依据选择高神经质和低神经质2组共24名被试,以有时间压力的心算和复杂辨别反应操作为紧张性刺激,在进行作业的同时记录被试的呼吸频率、呼吸流量、脉率、指端血管容积和皮肤电反应等五项生理指标,并检测尿内儿茶酚胺分泌量。通过对人格类型、作业成绩、作业难度主观评价、紧张性情绪体验,以及对尿内儿茶酚胺分泌量和五项生理指标的综合分析,以研究人格类型对应激反应影响的程度和途径。结果表明,在两组被试作业成绩无显著差异的情况下,在对作业难度主观评价和情绪体验的程度上,高神经质组高于低神经质组。在平静状态下,高神经质组去甲肾上腺素分泌量高于低神经质组;应激状态下,高神经质组的儿茶酚胺反应强度和变化幅度均明显高于低神经质组。高神经质组的五项生理指标均比低神经质组有较大的变化幅度。儿茶酚胺分泌量与脉率有明显的正相关。另外,通过与自然应激源部分的实验结果比较,发现实验室与现场应激的效果基本一致。     

The assessment of gender role stress for Chinese

The present study aimed to extend the generality of the construct of gender role stress (GRS) to Chinese samples. Specific objectives included (1) devising Chinese versions of the Masculine Gender Role Stress Scale (MGRS) and Feminine Gender Role Stress Scale (FGRS) developed by Eisler and his colleagues (2) examining the relationship between GRS and gender role orientation, and (3) evaluating the concurrent validity of GRS by correlating it with a measure of health adjustment. Fifty-one male and 58 female Chinese college students in Hong Kong participated in Study 1, which aimed to develop Chinese versions of the two GRS scales. Similar to Americans, Chinese male students scored higher on the MGRS scale, but lower on the FGRS scale than Chinese female students. Students' scores on the two GRS scales were independent from their global ratings of stereotypic masculinity and femininity. A second sample, consisting of 46 male and 73 female Chinese nurses, was recruited for Study 2, which evaluated the association between GRS and health adjustment. As hypothesized, a high level of MGRS or FGRS was positively related to a high level of health and mental health disturbances for both male and female nurses.This study was funded in part by the Asia Scholarship for Research on Women 1992/93 of the United Board for Christian Higher Education. The authors would like to thank Professor Richard M. Eisler for his permission to translate the MGRS and FGRS scales into Chinese, and the Association of Hong Kong Nurses for their assistance in data collection.     

三种心理测量理论的信度观

目前,心理测量领域中主要存在三大理论派别。本文分别对这三种理论即经典测验理论、可概括性理论和项目反应理论作了简要介绍,着重分析这三种理论的信度观。文章讨论了这三种信度观的理论基础和研究方法,比较了它们的异同,指出经典测验理论存在的一些不足及概化理论和项目反应理论所作的改进。概化理论是对经典测验理论的扩展,它用多维的信度指标（概化系数）替代了经典测验理论的信度系数,项目反应理论则从信息量的角度出发,用项目信息函数、测验信息函数等指标更具体深入地反映项目、测验的测量可靠程度。     

Teacher stress and guidance work in Hong Kong secondary school teachers

Major sources of stress in Hong Kong teachers were investigated, with specific reference to guidance work as a potential source of stress. A survey of 415 secondary school teachers revealed that guidance-related aspects of work constituted a major dimension of stress, with guidance teachers, female teachers, younger teachers and junior teachers perceiving more stress than their counterparts in this dimension. Workload and time pressure were perceived as the most stressful aspects of work for all teachers. Results also showed an association between stress and job satisfaction, and biographical variables. Implications of the findings for teachers doing guidance work in Hong Kong and internationally are discussed.     

体操运动员比赛时尿内儿茶酚胺的排出量

测量了37名体操运动员在比赛前和训练前的血压和脉率,并测了25名运动员赛前、赛后和训练后尿内儿茶酚胺的排出量。结果发现男子组赛前舒张压比训练前为高。比赛后尿内去甲肾上腺素排出量男女组均显著高于比赛前,男子组训练后尿内去甲肾上腺素排出量比比赛后略低,而女子组则比比赛后有明显降低。说明男子组去甲肾上腺素的排出增加与情绪的关系较少,而女子组则与情绪关系较密切。赛后肾上腺素排出量男女组均有明显增加,训练后排出量均比比赛后排出量低。女子组在赛前、赛后、训练后肾上腺素排出量均比男子组为低,但差异未达显著水平。比赛中发挥好的肾上腺素排出量倾向较低。     

入手术室时的情绪状态和某些心理、生理机能的联系及其和针麻效果的关系

情绪活动和某些生理机能或心理过程的关系很久以来就已进行过大量的研究。外科手术前患者的情绪状态及其相应的生理机能的变化,也曾受到注意。患者在意识清醒状态下进行针麻手术,他的情绪状态对针麻过程及其效果的作用如何,这种情绪状态和某些心理、生理机能有什么联系?这是针麻临床上和理论上应予探讨的问题之一。本工作试图综合分析患者的情绪状态和与之伴随的某些生理生化指标变化,以探讨
