A rational-emotive group intervention for preventing and coping with stress among safety officers

A stress management and prevention workshop for nonclinical industrial workers using rational-emotive principles with 18 months followup is reported. Twenty-two senior safety officers participated in an intervention program of five weekly meetings aimed at improving cognitive skills and assertiveness mainly by decreasing irrational thought processes. We hypothesized an increase in assertiveness, and a decrease in irrational beliefs, and emotional and cognitive stress symptoms (manifested in somatic complaints and cognitive weariness). Assertiveness improved and somatic complaints and irrationality decreased in the short term. Eighteen months later, cognitive weariness was also reduced. The other improvements were still evident, but not to the same extent as short-term effects. Although the workshop improved rationality, further practice would be needed in the behavioral aspect of stress prevention to achieve long-term improvements in assertiveness.Talma Kushnir, Ph.D., is a social and medical psychologist at the Occupational Health and Rehabilitation Institute, Raanana, Israel, and teaches psychology and health promotion at the Tel-Aviv University Medical School.Ruth Malkinson, Ph.D., fellow and RET trainer and supervisor of the Institute for RET, and teaches at the School of Social Work and Medical School at Tel-Aviv University, Israel.

母性应激对母性行为和心理功能的影响

成为母亲对女性而言是人生经历的特殊阶段, 她们在这个阶段发生的生理和心理的适应性改变对其自身和子代健康具有重要意义。母性应激是阻碍母亲适应性改变顺利进行的重要因素。母性应激会破坏人类母亲和雌性哺乳动物的母性行为、认知功能和情绪调节, 这种影响与糖皮质激素、催产素、催乳素等内分泌系统的调节失常; 母性环路、边缘系统及前额叶皮质等神经环路对刺激的神经反应改变以及神经发生、树突和突触重塑的可塑性变化有关。     

浅析上下班对个体身心健康的影响

在大多数工业化国家，来自社会的各阶层员工每天往返于家庭和单位之问，上下班的耗时性和上下班途中遇到的阻碍可能使人产生紧张状态，对个体的身心产生一定的影响，因此本文就上下班与个体的身心健康的关系进行了粗浅分析，以期使人们对其有更深的认识和把握。     

军事应激下的认知工效学研究

回顾了近20年来军事应激下的有关认知工效学研究,主要包括五部分：基本理论;应激对认知的影响;研究方法;处理应激的方法;总结。其中在研究方法中重点是对已有事故的分析,竞争性游戏和虚拟现实技术。在减少应激对认知不良影响的方法中值得注意的是：对抗应激人员的选拔、对人员的训练和能够对抗应激的人－机系统的开发。对于我军今后类似研究提供了思路和可能入手点     

急性情绪应激对大鼠行为和脑神经颗粒素磷酸化水平的影响

为探讨急性情绪应激对大鼠旷场行为的影响,以及脑神经颗粒素（Neuroganin,NG）变化与应激性行为效应之间的相互关系。以急性不确定性空瓶刺激,建立情绪应激动物模型。将40只雄性SD大鼠随机分为情绪应激组1（ES1,接受情绪应激和旷场测试）、情绪应激组2（ES2,只接受情绪应激）、正常对照组1（C1,无情绪应激,但接受旷场测试）和正常对照组（C2,无情绪应激,也无旷场测试）（n=10）。以旷场行为和高架十字迷宫任务来评定大鼠应激后的行为变化,Western印迹杂交法（Western blotting）测定海马和前脑皮层中的NG含量和磷酸化水平。结果表明：（1） 应激后ES1组的水平活动增加,与C1组比较,差异有显著性, p<0.01;（2）ES1组海马和前脑皮层的NG磷酸化水平高于C1和C2组,差异有显著性, 均为p<0.05; ES2组的前脑皮层NG的磷酸化水平高于C1组,差异有显著性,为p<0.05;（3） 海马的NG磷酸化水平与水平活动之间的相关达显著水平。提示急性情绪应激能导致动物明显的行为改变如焦虑,这种行为改变可能与脑内NG磷酸化水平的变化有关。水平活动可能是反映急性情绪应激的较敏感行为指标,海马NG磷酸化水平可能是预测急性情绪应激所致焦虑或抑郁行为的较敏感生物学指标     

不同应激范式对大鼠行为和脑神经颗粒素含量的影响

为探讨慢性情绪应激、生理应激对大鼠旷场行为和脑神经颗粒素（Neurogranin,NG）含量的不同作用,以及NG含量变化与应激性行为效应之间的相互关系。分别以不确定性空瓶刺激和饮水剥夺,建立情绪应激和生理应激动物模型。将40只雄性SD大鼠随机分为情绪应激组（ES）、生理应激组（PS）、定时饮水组（C1）和正常对照组（C2）（n=10）。以旷场行为任务来评定大鼠应激后的行为变化,Western blotting方法测定海马和前脑皮层中的NG含量。结果表明：应激后四组大鼠海马的NG含量差异无显著性;ES组前脑皮层的NG含量低于C2组,差异具有显著性,p<0.01;PS组的前脑皮层NG含量也下降,但与C2组相比差异无显著性; 应激后ES组、PS组修饰行为多于C2组,差异具有显著性,分别为p<0.01,p<0.05;前脑皮层NG含量与修饰行为之间的相关达显著水平。提示慢性情绪和生理应激均能导致前脑皮层NG含量下降,修饰行为增加,情绪应激作用更显著。修饰行为可能是反映情绪状态的较敏感行为指标,前脑皮层NG水平可能是预测情绪应激所致焦虑或抑郁行为的较敏感生物学指标。     

Reliability of the Chronic Mild Stress paradigm: Implications for research and animal welfare

The Chronic Mild Stress (CMS) model for depression has become central to the empirical literature on depression. There are however inconsistencies in the literature concerning the robustness of the phenomenon of anhedonia following CMS procedures. We report that not only did our procedures (modeled on the original reports) fail to induce an anhedonia, but in fact led to increased sucrose consumption. Furthermore, corticosterone levels following CMS procedures were lower than following control procedures. Given that this is not the first report of such findings, it is important to evaluate whether and which aspects of the experimental methodology are necessary or sufficient to induce the state of anhedonia.     

受灾情况和复原力对地震灾区中小学生创伤后应激反应的影响

进行心理援助之前,对都江堰安龙镇某九年制学校学生进行受灾情况、复原力和创伤后应激反应的测查,目的在于探讨受灾情况和复原力对中小学生创伤后应激反应的独立和交互影响,并为心理援助活动提供参考。结果表明：（1）在震后一个半月之时,该校有32%的学生出现较严重的创伤后应激反应;（2）有亲人遇难的学生在闯入、回避、警觉以及创伤后应激反应的总分上均显著高于无亲人遇难的学生;（3）复原力中的积极认知和信任两个维度对降低学生创伤后应激反应有比较大的作用;（4）复原力中的社会支持维度能够缓冲亲人遇难带来的负向影响     

Prevalence of mental health problems in Australian university health services

General practice patients report greater mental health problems than the general population, and students attending one university health service have reported greater prevalence rates at the end of the academic year. This study assessed the overall prevalence rate of mental health problems in university students using a cross‐sectional survey design of 1,168 students from three large, predominantly urban, Australian university health services. Approximately half of the students attending university health services reported elevated levels of psychological distress. The majority of severely distressed students had not sought any professional assistance for mental health problems. While there is scope for general practitioners to take a lead role in the identification of mental health problems in tertiary students, adequate treatment pathways need to be available. Implications for the role of universities in prevention work are discussed.     

Mindfulness-Based Stress Reduction in Medical Settings

Meditation, as a psychological intervention, has become of increasing interest to psychologists who conduct clinical research with or provide clinical services to medical populations. Mindfulness-based stress reduction (MBSR) is a manualized program which teaches a variety of meditation techniques and has frequently been used in medical settings with mixed medical populations. The following is a review of the literature, which provides preliminary support for the effectiveness of MBSR in specific medical populations, including persons with chronic pain, cancer and heart disease. Despite these encouraging findings, experts agree that continued research is needed, especially controlled studies with more rigorous methodology.
