创伤后心理复原的生理机制

心理复原是个体在经历对生命具有威胁的事件或严重的创伤后仍然能回复到良好适应状况的现象。对心理复原生理机制的研究存在两种研究取向：或从个人能力的角度,或从发展结果的角度。创伤记忆的抑制、大脑的可塑性、神经生物的调节以及基因、气质、情绪调节、认知过程、早期经验等保护因子的影响机制是研究的主要内容。文章最后对今后的研究进行了展望

通过对145名4~5岁儿童进行结构式访谈,调查幼儿假装游戏中假想角色现象的概况,包括假想同伴和角色扮演现象。结果如下:42.7%的儿童有假想同伴,绝大多数是玩具形式,女孩更多有假想同伴;男孩倾向于选择动物类型的假想同伴,而女孩倾向于人物类型;假想同伴绝大多为同性别并且比自己年龄小。44.8%的儿童有角色扮演活动,其中男孩倾向于装扮动画中的英雄人物,女孩倾向于装扮现实人物。     

损毁大鼠双侧内嗅皮质对束缚应激反应的影响

采用大鼠急性束缚应激动物模型,用鹅羔氨酸损毁大鼠双侧内嗅皮质来建立内嗅皮质损伤模型,观察束缚应激1小时后下丘脑室旁核快反应基因c-Fos表达情况以及应激后血浆促肾上腺皮质激素含量的动态变化,并与对照组相比较,探讨内嗅皮质与束缚应激反应的关系。结果表明,损毁内嗅皮质,明显抑制了应激诱导的下丘脑室旁核c-Fos的表达和血浆促肾上腺皮质激素含量的上升。结果提示,内嗅皮质参与调节束缚应激反应时HPA轴功能。

Bridging the Gap: How Supervisors’ Perceptions of Guanxi HRM Practices Influence Subordinates’ Work Engagement

This study aims to provide new insights into the relationship between supervisors' perceptions of guanxi human resource management (HRM) practices and their subordinates' work engagement. We used a three time‐lagged sample from 45 work groups and 205 employees in a state‐owned organisation (Study 1) and cross‐sectional data from 101 work groups and 413 employees in 101 different organisations (Study 2) to test our hypotheses. The results revealed that supervisors' perceptions of guanxi HRM practices were positively related to subordinates' perceptions of guanxi HRM practices, which, in turn, negatively affected subordinates' work engagement. This indirect effect was stronger when group power distance was low or when individual power distance orientation was low.     

Influence of the large–small split effect on strategy choice in complex subtraction

Two main theories have been used to explain the arithmetic split effect: decision‐making process theory and strategy choice theory. Using the inequality paradigm, previous studies have confirmed that individuals tend to adopt a plausibility‐checking strategy and a whole‐calculation strategy to solve large and small split problems in complex addition arithmetic, respectively. This supports strategy choice theory, but it is unknown whether this theory also explains performance in solving different split problems in complex subtraction arithmetic. This study used small, intermediate and large split sizes, with each split condition being further divided into problems requiring and not requiring borrowing. The reaction times (RTs) for large and intermediate splits were significantly shorter than those for small splits, while accuracy was significantly higher for large and middle splits than for small splits, reflecting no speed–accuracy trade‐off. Further, RTs and accuracy differed significantly between the borrow and no‐borrow conditions only for small splits. This study indicates that strategy choice theory is suitable to explain the split effect in complex subtraction arithmetic. That is, individuals tend to choose the plausibility‐checking strategy or the whole‐calculation strategy according to the split size.

Evaluating the Effectiveness of a Group CBT for Parents of ADHD Children

Improvements in parenting skills do not necessarily lead to improvements in child and parent outcomes for children with attention deficit and hyperactivity disorder (ADHD). Cognitive factors such as parental cognitions and parenting self-efficacy may influence such outcomes. Clinical research on the effects of cognitive-behaviour therapy (CBT) on parental cognitions, parenting self-efficacy and mental health in Chinese parents of children with ADHD is lacking. This quasi-experimental study intended to assess the effects of a culturally attuned group CBT treatment on the mental health and quality of life of Chinese parents aged 26–58 years, with children with ADHD in Hong Kong. Participants in the experimental group received group CBT and standard treatment and their counterparts in the control group received standard treatment. Primary outcome variables of mental health and quality of life and process variables including parenting stress, parenting efficacy and dysfunctional attitudes were measured at baseline, post-treatment and 3-month follow-up. Data were analysed using 2?×?3 ANCOVAs, Cohen’s d statistics and multiple mediation analyses. Group by time interactions were found for most outcome variables. Effect size statistics indicated that group CBT had small to moderate effects on most outcome variables at post-treatment and follow-up assessments. The effect of CBT on mental health was mediated by the reduction in parenting stress and the effect of CBT on quality of life was mediated by the reductions in parenting stress and dysfunctional attitudes. Given its potential benefit, it is worth considering incorporating this group CBT programme into interventions for Chinese parents with ADHD children.     

晚期癌症患者静脉管理的重要性

恶性肿瘤作为我国的常见病、多发病,其死亡率高居首位.手术、化疗和放疗成为现代医疗对于癌症的常见治疗手段.中晚期癌症患者作为癌症临床诊疗对象的主体,常伴有各种慢性疾病或营养不良.从而,化疗、中药辅助巩固治疗及营养支持治疗成为中晚期癌症患者临床治疗过程中的主体.治疗方法决定给药途径,静脉输液成为了中晚期癌症患者治疗肿瘤的主要手段之一.然而中晚期肿瘤患者静脉穿刺难度大,易发生输液渗漏和静脉炎等特点,以及各种高浓度强刺激性药物和输液器材对静脉血管造成的损伤,都对中晚期癌症患者的疾病治疗产生了不同程度的不利影响.对于中晚期癌症患者来说,静脉保护的程度直接关系到患者疾病治疗的进程及享受到的生命质量.因此,医护人员应对静脉输液致血管损害的相关因素予以高度重视及时采取血管维护的对策,同时加强对输液患者进行静脉维护知识的宣教,促使其树立静脉护理的意识和能力.     

Traits and stories: links between dispositional and narrative features of personality

Dispositional traits and life narratives represent two different levels of personality that have not previously been empirically linked. The current study tested five hypotheses connecting Big-Five traits to life-narrative indices of emotional tone, theme, and structure. Students (Study 1) and adults (Study 2) completed a self-report measure of the Big-Five traits and provided extended written accounts of either ten (students) or eight (adults) key life-narrative scenes, including life high points, low points, and turning points. Content analysis of the narrative data revealed that for both samples Neuroticism was positively associated with an emotionally negative life-narrative tone, Agreeableness was correlated with narrative themes of communion (e.g., friendship, caring for others), and Openness was strongly associated with the structural complexity of life narrative accounts. Contrary to prediction, however, Conscientiousness was not consistently associated with themes of agency (e.g., achievement, self-mastery) and Extraversion was unrelated to positive narrative tone. The results are discussed in the context of contemporary research and theorizing on the narrative study of lives and the relation of narrative research in personality to more conventional, trait-based approaches.
