慢性应激对大鼠行为和免疫细胞热休克蛋白70表达的影响

目的：研究慢性不确定应激对大鼠急性整体热水浴后外周血和脾脏免疫细胞热休克蛋白70（Heat shock protein 70, HSP70）表达的影响。方法：随机将大鼠分成慢性应激组和控制组（每组14只）。通过4周的慢性不确定性应激诱发实验组大鼠明显的抑郁行为,此期间控制组大鼠正常饲养。随后给予大鼠42度整体热水浴刺激,维持直肠温度41度25min。热刺激后6h,采用流式细胞仪测定大鼠外周血和脾脏免疫细胞HSP70 水平。结果：与控制组大鼠相比,慢性应激大鼠在急性热刺激后HSP70合成明显减少。控制组大鼠的所有被检测的免疫细胞热应激后HSP70合成均明显增加。相反,慢性应激大鼠仅在外周血的单核细胞和粒细胞检测到HSP70合成增加,同时升高的水平明显低于控制组大鼠。结论：慢性应激降低大鼠免疫细胞HSP70的热诱导反应,提示HSP70保护性作用减弱可能参与了慢性应激损害免疫细胞功能的生物学过程     

早期应激对抑郁相关行为及神经内分泌反应的长期影响

临床研究发现,早期创伤性经历是导致成年抑郁症易感性增加的高风险因素之一。但早期应激通过何种途径对抑郁发病产生长期的影响,目前尚不清楚。本文综述了近年来有关的实验动物研究,从早期应激的动物模型建立、早期应激对成年动物抑郁相关行为及神经内分泌反应的长期影响等方面进行了系统论述和分析,进而提出了早期应激并不影响动物的本能行为,但早期应激影响与行为动机和应激应对等认知相关的行为的观点,进一步论证了早期应激是通过增加个体潜在的易患病素质对抑郁症发病产生影响     

情绪劳动：表层动作与深层动作，哪一种效果更好？

情绪劳动（表层动作和深层动作）,哪一种情绪劳动的效果更积极？该项研究结合“情绪调节”和“双任务”的实验范式,以指导语引起不同的情绪劳动,以电影片段诱发负情绪（以悲伤为主）,同时测量情绪劳动过程情绪的变化,并通过数学成绩和自我真实感检测情绪劳动对后续工作和心理上的作用。结果表明：（1）操作表层动作与深层动作都具有一定的难度,需要付出一定的努力;且深层动作引起更多的精力集中;（2）表层动作和深层动作都可以减弱已被诱发的悲伤情绪,深层动作引起了更大的生理激活（R-R间期增加较小）;（3）表层动作导致后续工作成绩降低,自我真实感减弱。结论：如果需要在负情绪（悲伤）状态下展现正情绪（微笑）,深层动作是更积极的情绪劳动方式     

军事应激障碍的评估与防治

军事应激障碍是部队常见的心理障碍,也是严重影响部队战斗力的主要因素。探讨军事应激障碍的评估方法和防治措施是军事心理学研究的重要内容。本文系统地回顾了国内外军事应激障碍的评估原则和方法,并结合过去的研究成果,提出了军事应激障碍的防治措施。目的是为我军制定切实可行的军事应激防治措施提供科学依据,以维护部队官兵的心理健康,提高部队的战斗力     

内-外倾人格对情绪调节的影响及神经机制

内—外倾人格(即外倾性)是与情绪活动密切相关的人格特质：该特质不但影响人类的适应能力与主观幸福感，还与焦虑、冲动等情绪—行为障碍的产生有密切关联。在以往研究中，外倾性与情绪健康的关系集中体现为内—外倾人格对情绪事件易感性的影响，如外倾人格得分的增高伴随着对奖赏刺激更强的积极情绪反应水平。然而，上述联系也有可能是由于外倾性不同的人群具有不同的情绪调节特点导致。因此，可通过系统操纵外倾性人格因素与情绪调节方式，从外倾性人格特质对情绪调节方式及调节效果影响的角度，深入探讨外倾性和人类情绪与健康的关系。拟综合使用行为调查与生理测量、EEG/ERP 与 fMRI 手段，开展如下三个层面的研究工作：1)情绪调节问卷的编制及内、外倾人群情绪调节策略的比较研究；2)外倾性对情绪调节的影响及其脑机制研究，探讨认知情绪调节的生理变化、时间进程及神经基础与内—外倾人格的关系；3)情绪稳定性不同的内、外倾人群其情绪调节的特点及其脑机制研究。通过上述系列研究，深化对情绪与人格关系的认识，从而为心理健康的维护，情绪障碍的治疗及相关疗法的开发应用奠定理论基础。     

Enhancing the Benefits of Written Emotional Disclosure Through Response Training

Writing about a personal stressful event has been found to have psychological and physical health benefits, especially when physiological response increases during writing. Response training was developed to amplify appropriate physiological reactivity in imagery exposure. The present study examined whether response training enhances the benefits of written emotional disclosure. Participants were assigned to either a written emotional disclosure condition (n = 113) or a neutral writing condition (n = 133). Participants in each condition wrote for 20 minutes on 3 occasions and received response training (n = 79), stimulus training (n = 84) or no training (n = 83). Heart rate and skin conductance were recorded throughout a 10-minute baseline, 20-minute writing, and a 10-minute recovery period. Self-reported emotion was assessed in each session. One month after completing the sessions, participants completed follow-up assessments of psychological and physical health outcomes. Emotional disclosure elicited greater physiological reactivity and self-reported emotion than neutral writing. Response training amplified physiological reactivity to emotional disclosure. Greater heart rate during emotional disclosure was associated with the greatest reductions in event-related distress, depression, and physical illness symptoms at follow-up, especially among response trained participants. Results support an exposure explanation of emotional disclosure effects and are the first to demonstrate that response training facilitates emotional processing and may be a beneficial adjunct to written emotional disclosure.     

Aboriginal Practitioners Offer Culturally Safe and Responsive CBT: Response to Commentaries

We appreciate the valuable commentaries that have been provided for our paper “Can CBT be effective for Aboriginal Australians? Perspectives of Aboriginal practitioners trained in CBT.” The international authors identify how CBT, with adaptations by culturally responsive practitioners can be of value for non‐Western and Indigenous peoples. The commentary by Australian psychologists Dudgeon and Kelly questions the value of CBT for Indigenous Australians, terming it a “Western therapy” that is “culturally unresponsive” and “culturally blind.” They also critique the methodology of the study. We argue that CBT can be adapted by culturally competent practitioners to be culturally safe in Australia, as elsewhere. Cultural safety is mostly a function of the therapist, not the therapy. In the Bennett‐Levy et al. (2014) study, CBT was delivered in a culturally responsive way by Aboriginal counsellors within their own communities. CBT is a particularly adaptable and versatile therapy, and embodies principles of empowerment and self‐determination that are central to Indigenous social and emotional well‐being. We are concerned that CBT, which has strong empirical support and has been adapted elsewhere for a range of cultures, including Indigenous cultures, may be being denied to Indigenous Australian clients. There is considerable opportunity to evaluate the effectiveness and versatility of CBT, and variations of its mode of delivery, for all Australians.     

The relationship between greater mindfulness and less subjective experience of chronic pain: Mediating functions of pain management self‐efficacy and emotional intelligence

Previous research shows a connection between greater mindfulness and less subjective experience of pain. The present study examined whether pain management self‐efficacy and emotional intelligence mediate this relationship in individuals experiencing chronic pain. Two hundred participants experiencing chronic pain completed measures of mindfulness, experience of pain, pain management self‐efficacy, and emotional intelligence. Greater mindfulness was associated with less subjective experience of pain, greater pain management self‐efficacy, and more emotional intelligence. More pain management self‐efficacy and higher emotional intelligence were associated with less subjective experience of pain. Emotional intelligence and pain management self‐efficacy significantly mediated the relationship between mindfulness and pain. The connection between greater mindfulness and less subjective experience of pain may be due to mindfulness providing a foundation for emotional functioning and behavioural regulation that result in reductions in the experience of pain.
