This study aims to elucidate cognitive and contextual aspects of the EE (Expressed Emotion) concept. The EE levels of both parents of two first admission psychotic patients were rated from the Five Minute Speech Sample (FMSS), and the emotional responses were further analyzed in narratives of family photographs. The attribution model was found to provide an explanatory framework for understanding relatives' expressed emotions (EE) toward a family member suffering from psychotic disturbances. Four case reports indicated that family photographs induced parents to create narratives in which emotions, attributions, and strategies for coping with stressful aspects of the illness came forward as intertwined phenomena. The method can offer more comprehensive data for intervention strategies aiming to alter the prevailing atmosphere and interaction patterns within the high EE family.  相似文献

From the narrative point of view the plot of a story configures time. In psychosis, when experiences remain unnarrated, experience being-in-time is also missing. Once experiences are given narrative form, they can be left behind as a part of individual's personal history, thus enabling present experiences to be narrated. Unnarrated experiences do not accumulate. Narrative history contains, however, enough redundancy to invite you to restory your past in a new way if you need to. Hence, from the narrative point of view, early, family- and network-centered intervention is of special value in cases of acute psychosis.  相似文献

The present study explored the intrinsic event-related potential (ERP) features of the effects of acute psychological stress on the processing of motion-in-depth perception using a dual-task paradigm. After a mental arithmetic task was used to induce acute psychological stress, a collision task was used to evaluate motion-in-depth perception. The error value and average amplitude of late slow waves (SW) were significantly larger for the earlier colliding spheres’ than for the later colliding spheres. The P1 peak latency in the left occipital region was significantly shorter than that of the right occipital region in the motion-in-depth perception task. Compared to the control condition, the estimated value of residual time-to-collision and error value were significantly reduced, and the N1 peak amplitude and the SW averaged amplitude were significantly increased in the stress condition. Longer motion-in-depth time improved discrimination accuracy and decreased the investment of cognitive resources. Acute psychological stress increased behavioral performance and enhanced attention resources on the motion-in-depth perception task together with greater investment of cognitive resources.  相似文献

Serum testosterone and cortisol levels were measured by radioimmunoassay in 14 young male judo competitors, in samples taken 10 minutes before and 45 minutes after two different procedures. The first involved physical exercise and the second competitive fighting. Both procedures were of 5 minutes duration and sessions took place at the same time (between 10:00 A.M. and 12:00 P.M. local time) but on different days. Comparing the two situations over all subjects revealed that testosterone increased after exercise and decreased slightly after Competition. Between subject comparisons suggested that contrary to previous claims, winning or losing did not significantly change the testosterone and cortisol levels. Comparisons of subjects who were members of the Regional Team with individuals who were not part of that group confirmed that members increased their testosterone levels after competition, whereas the nonmembers showed a significant decrease. Moreover, success of the individuals, in their sporting record, correlated positively and significantly with the changes of testosterone observed during the competition. These preliminary results suggest that previous personal experience of success can influence the pattern of the psychoendocrine response to a contest situation.  相似文献

急性应激会增强个体对威胁刺激的注意偏向, 但急性应激是增强了对威胁刺激的注意定向还是损害了对威胁刺激的注意解除还不清楚。本研究采用社会评估冷压任务和点探测任务, 结合事件相关电位技术, 考察急性应激对威胁刺激注意偏向影响的认知机制。在进行社会评估冷压任务后, 应激组个体的状态焦虑和皮质醇浓度显著升高。在注意偏向中, 应激组对威胁刺激的注意解除比控制组更慢, 应激组和控制组在对威胁刺激的注意定向上无显著差异。ERP结果上, 威胁刺激诱发应激组比控制组产生了更负的SPCN, 在N2pc上没有显著差异。应激组和控制组皮质醇增量的差异和N2pc、SPCN的组间差异均有显著正相关。这些结果说明, 急性应激增强对威胁刺激的注意偏向是因为其损害个体对威胁刺激的注意解除, 这可能是因为急性应激损害了与注意解除相关的额-顶网络的功能所致。  相似文献

生活中, 个体会时时关注自己的行为结果并及时做出调整以适应环境的变化。但在应激下个体能否有效地监控行为并做出适应性调整依然未知。本研究招募了52名男性大学生被试, 将其随机分入应激组与控制组, 采用特里尔社会应激测试(Trier Social Stress Test, TSST)诱发个体的应激反应, 并结合错误意识任务(Error Awareness Task, EAT)探索个体急性应激下的错误监控与错误后调整过程。应激指标的结果显示应激组个体在应激任务后唾液皮质醇、心率、应激感知自我报告和负性情绪均显著高于控制组, 表明急性应激的诱发是成功的。行为结果显示应激组的错误意识正确率显著低于控制组, 错误意识反应时显著短于控制组; 进一步地, 应激组个体在意识到错误之后的试次上正确率显著低于未意识到错误之后的试次, 并且应激组个体在意识到错误之后的试次上正确率低于控制组。结果表明急性应激降低了个体对错误反应的监控水平, 即便在辨别出错误反应的情况下, 个体的行为监控与调节也更差。本研究说明急性应激会损伤行为监控系统, 导致个体的行为适应性下降。  相似文献

The study tested the efficacy and tolerability of cognitive processing therapy (CPT) for survivors of assault with acute stress disorder. Participants (N = 30) were randomly allocated to CPT or supportive counseling. Therapy comprised six individual weekly sessions of 90-min duration. Independent diagnostic assessment for PTSD was conducted at posttreatment. Participants completed self-report measures of posttraumatic stress, depression, and negative trauma-related beliefs at pre-, posttreatment, and 6-month follow-up. Results indicated that both interventions were successful in reducing symptoms at posttreatment with no statistical difference between the two; within and between-group effect sizes and the proportion of participants not meeting PTSD criteria was greater in CPT. Treatment gains were maintained for both groups at 6-month follow-up.  相似文献

Anxiety and depression are highly prevalent and disabling mental health disorders, with comorbidity often posing as a barrier to successful treatment outcomes, thus creating a need for more intensive treatment options. Outpatient clinicians are more likely to refer patients with severe symptoms of anxiety and depression to inpatient hospitalizations rather than partial hospital programs (PHPs) or intensive outpatient programs (IOPs), despite evidence that inpatient hospitalization is associated with high costs and other risks following discharge. The present study reviews two case studies of patients who received cognitive-behavioral therapy/dialectical behavior therapy (CBT/DBT)-based IOP treatment in a private New York clinic. We evaluated treatment outcomes for 73 adult patients (50.7% female) with a mean age of 29.10 years (SD = 10.30). At intake, patients averaged 2.15 diagnoses (SD = 0.94, range = 4) and the majority (80.8%) were prescribed psychotropic medication. Treatment was structured and individually tailored, with patients receiving an average of 21.77 hours (SD = 15.06) of psychotherapy over 12.63 treatment sessions (SD = 9.76), across 12.21 days (SD = 9.61). We observed a clinically and statistically significant change in symptoms of anxiety (t = 6.24, p < .001), depression (t = 5.55, p < .001), and suicidality (t = 2.32, p < .05) over the course of the IOP. After completing treatment, 68.1% of participants tapered down to once-weekly treatment. The present study highlights the clinical utility of an IOP and suggests that this approach can be effective for adult patients presenting with severe symptoms of anxiety and/or depression.  相似文献

羧化不全骨钙素(ucOCN)是骨中成骨细胞分泌的特异性蛋白, 因其在调控神经发育、神经可塑性等中的重要角色而受到神经科学领域关注。“骨-脑”串联“对话”是骨内分泌-神经介导的应答系统, ucOCN透过血脑屏障后介导单胺类神经递质、神经内分泌、神经免疫、神经再生及基因表达等机制, 进而作用于海马CA3区、扣带回等脑区功能发挥来调节抑郁发生及改善。而ucOCN作为骨源性力学刺激敏感基因, 运动上调其表达后进入血液循环, 通过介导5-HT/GABA分泌、HPA轴功能、炎症反应、神经营养因子(BDNF等)表达或信号途径(如GSK3β/β-catenin、TLR4/miR-223/NLRP3等)激活等来实现“骨串联脑”, 发挥运动抗抑郁作用。通过对骨源性因子ucOCN介导脑区功能变化从而实现运动抗抑郁的作用机制进行探讨、梳理, 一方面有助于更深入了解骨内分泌功能, 另一方面为抑郁发生、改善和运动抗抑郁研究提供新的理论基础和研究思路。  相似文献

为比较替格瑞洛与氯吡格雷对急性ST段抬高型心肌梗死(STEMI)患者急诊经皮冠状动脉介入术(PCI)术后炎症因子的影响,将176例急性STEMI且行急诊PCI术的患者分为替格瑞洛组(A组)58例、氯吡格雷常规组(B组)58例、氯吡格雷强化组(C组)60例,分别测定术前、术后12小时、术后7天、术后1个月、术后3个月、6个月时炎症因子e反应蛋白(CRP)、白细胞介素-6(IL6)、髓过氧物酶(MPO)、可溶性CD40受体(sCD40L)的含量,比较3组患者各炎症因子在不同时间点有无统计学差异。结果显示c组和A组较B组明显降低(P〈0.05),有统计学意义,而A组较c组稍降低(P〉0.05),但两者无统计学意义。由此可见,替格瑞洛的抗炎作用较常规剂量氯吡格雷作用明显增强,和强化剂量氯吡格雷作用相仿。  相似文献
