突发公共卫生事件下心境障碍的特点与应对

突发公共卫生事件会给较大范围的人群造成相当的心理压力和情绪问题。突发事件发生时,社会心理因素对突发事件控制效果和进程的影响越来越显著,因疫情、疾病、生活、工作以及社会和人际关系等因素而致的情绪问题非常突出。突发事件时情绪问题的表现有疑病、恐慌、焦虑、抑郁和强迫心理等,对此应采取相应的对策,而不同群体如罹患人群、隔离人群、家属、普通就医者及一般公众的情绪问题有其独特的表现和应对措施。突发事件为情绪问题的研究提供了广阔的前景。     

青少年自我复杂性的测量及其压力缓冲作用探讨

研究主要探讨了青少年自我复杂性的测量及其压力缓冲作用。结果表明,Rafaeli-Mor等人（1999）的成分测量法能更有效地评价自我复杂性;累积压力下,更高数量的自我维度意味着青少年更高的满意度;当前压力下,自我维度的高数量/高重叠使青少年的自我清晰、连贯,较少产生抑郁;高数量/低重叠意味着自我分裂,青少年易受消极事件的影响;低数量/高重叠表明自我相对简单或狭隘,青少年难以应付生活的高压力;自我复杂性是影响弹性的主要因素之一     

‘I never talked about,ever’: A comprehensive process analysis of a significant client disclosure event in therapy

Aims: The present study was intended to examine how a particular client disclosure came about and what made it important to the client. Method: A client‐identified significant therapy event involving disclosure of childhood abuse was analysed using Comprehensive Process Analysis (CPA), a qualitative interpretive method for examining the process, effects and context of significant events in therapy. Results: The analysis identified therapist invitation and client universalisation as the key elements of the disclosure event. The context analysis showed how the event linked to the client's symbolisation of her fear earlier in the session and in the previous session. The client gained insight into how the earlier abuse had affected her life, linking it to the victimisation that was her primary reason for seeking therapy, and to her relationship with her mother. The therapist facilitated the event by following up the client's hints, trusting the strength of the alliance, and staying close to the client's frame of reference. Conclusion: The findings suggest that the initial significance of an invited disclosure event may diminish for a client over the course of therapy.     

5-HTTLPR与抑郁相关性的研究动态

摘 要 5-HTTLPR是5-羟色胺转运蛋白基因启动子区域上的多态性位点,对其转录效率具有调节作用。5-HTTLPR基因型与抑郁存在相关,但必须把二者的关系置于一个多基因与环境交互作用的框架下考察。一方面,环境因素的作用不容忽视：S等位基因携带者暴露于负性生活事件时,表现出更多情绪问题,更易发生抑郁。另一方面,CYP2C9、BDNF等基因与5-HTTLPR有交互作用,共同影响抑郁的发生。此外,年龄、性别等因素会对研究结果造成混淆。未来研究应侧重于对机制的探讨。     

Factors affecting medial temporal lobe engagement for past and future episodic events: an ALE meta-analysis of neuroimaging studies

Remembering the past and envisioning the future are at the core of one's sense of identity. Neuroimaging studies investigating the neural substrates underlying past and future episodic events have been growing in number. However, the experimental paradigms used to select and elicit episodic events vary greatly, leading to disparate results, especially with respect to the laterality and antero-posterior localization of hippocampal and adjacent medial temporal activations (i.e., parahippocampal, entorhinal and perirhinal cortices, amygdala). Although a central concern in today's literature, the issue of hippocampal and medial temporal lobe laterality and antero-posterior segregation in past and future episodic events has not yet been addressed extensively. Using the activation likelihood estimation (ALE) procedure (Turkeltaub, Eden, Jones, & Zeffiro, 2002), we performed a meta-analysis of hippocampal and adjacent medial temporal coordinates extracted from neuroimaging studies examining past remembering and future envisioning. We questioned whether methodological choices could influence the laterality of activations, namely (1) the type of cue used (generic vs. specific), (2) the type of task performed (recognition vs. recall/imagine), (3) the nature of the information retrieved (episodic vs. "strictly" episodic events) and (4) the age of participants. We consider "strictly" episodic events as events which are not only spatio-temporally unique and personal like episodic events, but are also associated with contextual and phenomenological details. These four factors were compared two-by-two, generating eight whole-brain statistical maps. Results indicate that (1) specific cues tend to activate more the right anterior hippocampus compared to the use of generic cues, (2) recall/imagine tasks tend to recruit more the left posterior parahippocampal gyrus compared to recognition tasks, (3) (re/pre)experiencing strictly episodic events tends to activate more the bilateral posterior hippocampus compared to episodic events and (4) older subjects tend to activate more the right anterior hippocampus compared to younger subjects. Importantly, our results stress that strictly episodic events triggered by specific cues elicit greater left posterior hippocampal activation than episodic events triggered by specific cues. These findings suggest that such basic methodological choices have an impact on the conclusions reached regarding past and future (re/pre)experiencing and their neural substrates.     

Stressful Events and Temperament Change during Early and Middle Adolescence: The TRAILS Study

This project investigates how stressful events are related to deviations from normative temperament development during adolescence. Temperament traits were assessed at ages 11 and 16 years. Life‐event data was captured using an interview (total n = 1197). Normative changes were found in all traits. A linear trend was found between the experience of stressful events and temperament development. Adolescents exposed to stressful events showed smaller decreases in fear and shyness, stronger decreases in effortful control and affiliation and smaller increases in high intensity pleasure. Exposure to stressful events was related to increases in frustration instead of decreases. Our results show that whereas normative development is mostly in the direction of maturation, adolescents who experienced stressful events showed less maturation of their temperament.

What constitutes traffic event severity in terms of human danger perception?

This study focuses on the severity gradation of non-collision events. Earlier theoretical work has suggested that a proper severity measure for an event should reflect the risk of personal injury, which is often split into two components, including the risk of a collision and the potential consequences had the collision taken place. While a great number of severity measures have been suggested, most of them fail to address both components, thus resulting in counter-intuitive event gradations and inconclusive outcomes in validation studies. Conversely, it has been shown that human observers often show very good agreement when given a task to rank traffic situations by their severity or level of danger. The aim of this study is to investigate in depth how human judgements of the severity of traffic situations can be expressed by means of objective safety indicators. In this study, a set of video-recorded traffic situations, in which a cyclist passes straight through an intersection while a left or right-turning motor vehicle crosses the cyclist’s path, were analysed. Binary logistic regression was used to develop models assessing the most important traffic severity indicators associated with human feelings of danger. The results showed that the initial conditions of a traffic event, defined as a start of an evasive action, contain the most important information for explaining its severity. Moreover, variables related to both proximity and collision consequences are important and should be integrated into severity measures.     

Why did this happen to me? Religious believers’ and non-believers’ teleological reasoning about life events

People often believe that significant life events happen for a reason. In three studies, we examined evidence for the view that teleological beliefs reflect a general cognitive bias to view the world in terms of agency, purpose, and design. Consistent with this hypothesis, we found that individual differences in mentalizing ability predicted both the tendency to believe in fate (Study 1) and to infer purposeful causes of one’s own life events (Study 2). In addition, people’s perception of purpose in life events was correlated with their teleological beliefs about nature, but this relationship was driven primarily by individuals’ explicit religious and paranormal beliefs (Study 3). Across all three studies, we found that while people who believe in God hold stronger teleological beliefs than those who do not, there is nonetheless evidence of teleological beliefs among non-believers, confirming that the perception of purpose in life events does not rely on theistic belief. These findings suggest that the tendency to perceive design and purpose in life events—while moderated by theistic belief—is not solely a consequence of culturally transmitted religious ideas. Rather, this teleological bias has its roots in certain more general social propensities.
