应激影响脑老化的相关学说与机制

应激是机体受到各种内外环境因素刺激时的适应性反应,当反应持续时间过久或长期处于激活状态,则会对机体产生不良影响。目前认为,老化与糖皮质激素的过量分泌所致大脑相关区域的损伤相关,这些区域不仅参与认知与情绪,而且与下丘脑-垂体-肾上腺轴控制的其他活动相关。除此之外,皮质醇基础水平的差异性、皮质醇在脑内的可用性、糖皮质激素受体的失衡及大脑本身的易损性、回弹性等都是应激影响脑老化的参与因素。本文将对应激所致正常或非正常老化过程的相关影响机制与学说进行综述。     

Work stress and employee well‐being: The critical role of Zhong‐Yong

In the pursuit of well‐being at work, work stress is always an inescapable challenge. However, existing research shows that the relationships between work stress and employee outcomes are inconsistent, which indicates that the concept of work stress needs further investigation. Moreover, Zhong‐Yong serves as a cognitive strategy to coping with stress as well as being a pivotal life wisdom and practical rationality. Using a questionnaire survey, this study explores the relationship between work stress, employee well‐being, and Zhong‐Yong beliefs. The work stress was classified into challenge‐ and hindrance‐related stress while emotional exhaustion and job satisfaction were used as well‐being indicators. Using a sample of 394 employees from private enterprises in Taiwan as subjects, the results show that (1) hindrance‐related stress is destructive to employee well‐being; (2) challenge‐related stress is positively associated with emotional exhaustion but has no significant relation with job satisfaction; (3) Zhong‐Yong beliefs mitigate the harm from hindrance‐related stress on employee well‐being; and (4) Zhong‐Yong beliefs weaken the negative effects of challenge‐related stress on emotional exhaustion, and transform challenge‐related stress into eustress for job satisfaction.     

Loss and the Organization of Affect

The present studies evaluated the association between positive affect (PA) and negative affect (NA) following romantic relationship loss experiences, as well as following less stressful romantic relationship situations, given theoretical evidence that the structure of affect may differ following a relationship loss. Across two studies, evidence suggested that the association between NA and PA was more strongly inverse following romantic relationship loss experiences when compared to less stressful relationship experiences. Such findings provide important implications for the study of romantic relationship loss, as well as the treatment of psychopathology following romantic relationship loss.     

Psychotherapeutic Interventions for Symptom Reduction in Veterans With PTSD: An Observational Study in a Residential Clinical Setting

Cognitive processing therapy (CPT) and eye movement desensitization and reprocessing (EMDR) therapy were compared for veterans in a posttraumatic stress disorder (PTSD) residential program (N = 51) who received individual EMDR and group CPT, individual CPT and group CPT, or trauma group exposure (TGE) therapy. Analyses revealed an overall significant difference on posttest measures of the PTSD Checklist for individual EMDR/group CPT and individual CPT/group CPT when compared to TGE, with no significant difference found between EMDR and CPT. Depression scores were significantly decreased between pre- and posttest for patients who received individual EMDR/group CPT. Results support EMDR and CPT as clinically effective and complementary treatments in residential PTSD treatment programs.     

Social integration buffers stress in New York police after the 9/11 terrorist attack

Being socially integrated is regarded as a protective factor enabling people to cope with adversity. The stress-buffering effect reflects an interaction between stress and a social coping resource factor on subsequent outcomes. This study, based on 2943 police officers, examines mental health outcomes among officers who responded to the 9/11 terrorist attack on the World Trade Center. The Wave 1 data collection took place between September 2003 and November 2004 with a follow-up study (Wave 2) conducted from November 2006 through December 2007. A moderated mediation model was specified that uses event exposure as a distal predictor, earlier stress response as a mediator, and later stress response as an outcome, and social integration as a moderator of this relationship. The mediation hypothesis was confirmed, and moderation occurred at two stages. First, there was a multiplicative relationship between exposure levels and social integration: The higher the exposure level, the more stress responses occur, but this effect was buffered by a high level of social integration. Second, Wave 1 stress interacted with social integration on Wave 2 stress: The more the police officers were socially integrated, the lower the Wave 2 stress, which happened in a synergistic manner. The findings contribute to the understanding of mediating and moderating mechanisms that result in health outcomes such as posttraumatic stress disorder or resilience.     

Computer-based written emotional disclosure: the effects of advance or real-time guidance and moderation by Big 5 personality traits

Standard written emotional disclosure (WED) about stress, which is private and unguided, yields small health benefits. The effect of providing individualized guidance to writers may enhance WED, but has not been tested. This trial of computer-based WED compared two novel therapist-guided forms of WED – advance guidance (before sessions) and real-time guidance (during sessions, through instant messaging) – to both standard WED and control writing; it also tested Big 5 personality traits as moderators of guided WED. Young adult participants (n = 163) with unresolved stressful experiences were randomized to conditions, had three, 30-min computer-based writing sessions, and were reassessed six weeks later. Contrary to hypotheses, real-time guidance WED had poorer outcomes than the other conditions on several measures, and advance guidance WED also showed some poorer outcomes. Moderator analyses revealed that participants with low baseline agreeableness, low extraversion, or high conscientiousness had relatively poor responses to guidance. We conclude that providing guidance for WED, especially in real-time, may interfere with emotional processing of unresolved stress, particularly for people whose personalities have poor fit with this interactive form of WED.     

Emotional suppression explains the link between early life stress and plasma oxytocin

Early life stress (ELS) has been found to be associated with lower concentrations of plasma oxytocin (OT) in adulthood. It is not yet clear, however, what mechanisms underlie this association. The goal of the present study was to test the role of emotional suppression as an intervening variable between ELS in childhood and plasma OT. In a nonclinical sample of 90 men, ELS, emotional suppression, and plasma OT were assessed. Emotional suppression was positively associated with ELS (r = 0.37, p < 0.001) and negatively associated with plasma OT concentrations (r = ?0.30, p < 0.01). In contrast, cognitive reappraisal – an alternative emotion regulation strategy – was not correlated with ELS or plasma OT concentrations. Cross-sectional regression analyses revealed that the ELS explained variance in plasma OT via emotional suppression. Moderation analyses revealed that the combination of high ELS and high emotional suppression was associated with the lowest concentrations of plasma oxytocin. These findings are consistent with the view that emotional suppression may be one pathway linking ELS and OT.

Job skill discretion and emotion control strategies as antecedents of recovery from work

Recovery from work protects employees’ health and well-being, and therefore it is important to understand its antecedents. The aim of this study conducted among 183 middle-aged participants drawn from the Finnish Jyväskylä Longitudinal Study of Personality and Social Development was to examine whether job skill discretion and emotion control strategies (emotional rumination and emotional inhibition) are related to psychological aspects of recovery from work (subjective recovery evaluation, psychological detachment and relaxation). The results of hierarchical general linear models confirmed the hypothesis that job skill discretion is positively associated with subjective recovery evaluation and relaxation. As expected, high emotional rumination predicted difficulties in psychological detachment and relaxation. Emotional inhibition moderated the relationship between job skill discretion and psychological detachment: where emotional inhibition was at a moderate level, job skill discretion was positively related to psychological detachment. The findings suggest that not only job characteristics but also individual factors contribute to recovery, revealing practical implications for employees, employers and occupational health care professionals seeking to promote employees’ work ability, health and well-being.
