灾后孤儿创伤后应激障碍的发生发展及其认知神经机制

灾后孤儿亲历双重重大创伤, 是创伤后应激障碍(post-traumatic stress disorder, PTSD)的高发群体; 同时, 巨大创伤对其认知功能和行为模式也带来一定程度的影响。本研究拟以灾后孤儿这一特殊群体为研究对象, 考察“PTSD发生发展及其认知神经机制”, 具体如下：(1) 采用序列研究设计, 展开灾后孤儿PTSD流行病学调查, 描述其PTSD发生发展、变化的轨迹和时程特点; (2) 展开横断研究, 考察灾后孤儿认知发展特点, 并通过结构方程模型, 揭示其PTSD发生发展的心理行为机制; (3) 采用眼动和脑电技术展开比较研究, 考察罹患PTSD孤儿的认知神经机制。本研究的研究结果将对今后的灾后孤儿安置及心理援助提供科学建议; 为有针对性地提供心理干预、制定心理干预的总体规划提供科学依据; 力争为今后孤儿的创伤心理的诊断、干预效果评估提供科学客观的指标和方法。     

情感强度不同负性生活事件对个体情感反应和行为选择的影响

采用系列实验方法探讨不同情感强度负性生活事件对个体情感反应和行为选择的影响。结果发现：（1）复合生活事件（1高负性+1低负性）为异类时,个体对复合事件的负性感受比单独1高负性事件更低,选择经历前者,出现平均效应;（2）复合生活事件为同类时,其负性感受比单独1高负性事件更高,选择经历后者,出现累加效应;（3）复合事件有明显的时间特点时,其情感和行为选择受事件发生时间影响,符合峰-终定律。结论：人们对负性生活事件的加工受其特点的影响,加工方式不同。     

Theoretical approaches to psychological trauma: Implications for research and practice

In recent years, a range of counselling and psychotherapy interventions have been developed in work with clients and patients suffering from the psychological effects of trauma. This paper outlines various theoretical models of psychological trauma, selected because they can specifically encompass both the external aetiology (i.e. the traumatic event) and also explain (to a greater or lesser extent) the enormous range of reactions to that event. These models are critically discussed in terms of their implications for counselling practice, and as guides to further research. Examples are given of ways in which the author has drawn on different theoretical frameworks to inform her own therapeutic practice in work with people experiencing post‐traumatic stress disorder.     

How others respond to non‐suicidal self‐injury disclosure: A systematic review

Non‐suicidal self‐injury (NSSI) is an increasing health concern. Despite the potential benefits of disclosing the behaviour, many decide not to do so because of the fear of negative social reactions. In this review, we examined the existing research on reported and perceived reactions to NSSI disclosure with the aim of identifying how an individual who discloses their NSSI perceives others' responses to this disclosure, with the ultimate goal of understanding how these reactions may impact those who disclose their NSSI. Among the initial 275 studies, 10 fit the inclusion criteria. Three studies reported perceived responses by individuals who had disclosed their NSSI; six studies examined self‐reported responses by others; one study focused on disclosures online. Individuals who disclosed their NSSI often received negative responses, which caused them to withdraw from seeking further help. On the other hand, recipients' reactions to NSSI disclosure varied based on NSSI characteristics such as its perceived cause and/or underlying motivation. Results highlight the importance of providing support rather than searching for the underlying drives of NSSI.     

How Did You Like This Course? The Advantages and Limitations of Reaction Criteria in Ethics Education

Ethics courses are most commonly evaluated using reaction measures. However, little is known about the specific types of reaction data being collected (e.g., content relevance, course satisfaction) and how these reaction data relate to improvements in trainee performance (e.g., knowledge, moral reasoning). Using a sample of 381 ethics training sessions, major reaction data categories were identified. Content and course satisfaction were the most frequently collected types of reaction criteria. Furthermore, content relevance (r = .84) and course satisfaction (r = .79) showed strong, positive relationships with performance criteria, whereas content satisfaction demonstrated a moderate, negative relationship (r = –.28). These results and future directions for ethics training evaluation are discussed.     

Brain-derived neurotrophic factor Val66met polymorphism and plasma levels in road traffic accident survivors

Background: Alterations in brain-derived neurotrophic factor (BDNF) expression and release may play a role in the pathogenesis of post-traumatic stress disorder (PTSD). Design: This study evaluated road traffic accident (RTA) survivors to determine whether PTSD and trauma-related factors were associated with plasma BDNF levels and BDNF Val66Met carrier status following RTA exposure. Methods: One hundred and twenty-three RTA survivors (mean age 33.2 years, SD?=?10.6 years; 56.9% male) were assessed 10 (SD?=?4.9) days after RTA exposure. Acute stress disorder (ASD), as assessed with the Acute Stress Disorder Scale, was present in 50 (42.0%) of the participants. Plasma BDNF levels were measured with enzyme-linked immunosorbent assay and BDNF Val66Met genotyping was performed. PTSD, as assessed with the Clinician-Administered PTSD Scale, was present in 10 (10.8%) participants at 6 months follow-up. Results: Neither BDNF Val66Met genotype nor plasma BDNF was significantly associated with the presence or severity of ASD or PTSD. Plasma BDNF levels were, however, significantly correlated with the lifetime number of trauma exposures. Conclusions: In RTA survivors, plasma BDNF levels increased with increasing number of prior trauma exposures. Plasma BDNF may, therefore, be a marker of trauma load.     

Loss Through Betrayal: An Analysis of Social Provision Changes and Psychological Reactions

Results of two retrospective studies suggested that romantic betrayal led to the loss of key aspects of social support from partners, most notably attachment, guidance, and reliable alliance with the partner. Furthermore, specific social provision losses were found to reliably predict recalled and current negative psychological states associated with romantic betrayal. Perceived attachment losses predicted postbetrayal anger and disgust, as well as trauma reactions following betrayal. In addition, a decline in reassurance of one’s worth following betrayal predicted embarrassment about the event, and the degree to which reliable alliance with the partner was lost predicted anxiety and shame.     

Stressful life events and predictors of post-traumatic growth among high-risk early emerging adults

Stressful life events (SLEs) may elicit positive psychosocial change among youth, referred to as post-traumatic growth (PTG). We assessed types of SLEs experienced, degree to which participants reported PTG, and variables predicting PTG across 24 months among a sample of high-risk, ethnically diverse, early emerging adults. Participants were recruited from alternative high schools (n = 564; mean age = 16.8; 65% Hispanic). Multi-level regression models were constructed to examine the impact of environmental (SLE quantity, severity) and personal factors (hedonic ability, perceived stress, developmental stage, future time orientation) on a composite score of PTG. The majority of participants reported that positive changes resulted from their most life-altering SLE of the past two years. Predictors of PTG included fewer SLEs, less general stress, having a future time perspective, and greater identification with the developmental stage of emerging adulthood. Findings suggest intervention targets to foster positive adaptation among early emerging adults who experience frequent SLEs.     

Reflection as a strategy to enhance task performance after feedback

An unanswered question in employee development is how reflection can be used for improving performance in organizations. Drawing from research and theory on dual-process models, we develop and test a reflection strategy to stimulate deeper learning after feedback. Results of two studies (N = 640 and N = 488) showed that reflection combined with feedback enhanced performance improvement on a web-based work simulation better than feedback alone. Reflection without feedback did not lead to performance improvement. Further analyses indicated that the proposed reflection strategy was less effective for individuals low in learning goal orientation, low in need for cognition, and low in personal importance as they engaged less in reflection. Together, these findings provide a theoretical basis for the future study of reflection in organizations and suggest a practical and cost-effective strategy for facilitating employee development after feedback in organizations.
