Le stress au travail : du paradigme des risques psychosociaux à celui de la qualité de vie au travail

An action research using three classical models of occupational stress enabled us to verify the impact on the results obtained from the choice of model and paradigm: psychosocial risks versus Quality of work life. Four hundred and thirty-six supermarket employees answered a questionnaire including these three measures of stress, the outcomes (satisfaction, fatigue) and a possible cause (role strain). Our results validate the hypotheses of significant differences in stress prevalence levels according to the model, such as links to the factor and the consequences, as well as the importance of the perception of stress to explain the negative experience.     

Meaning in life and violations of beliefs and goals: reciprocal relations among individuals with congestive heart failure

Background and objectives: In the context of highly stressful experiences, violations of beliefs and goals and meaning in life may have a reciprocal relationship over time. More violations may lead to lowered meaning, whereas higher meaning may lead to lowered violations. The present study examines this relationship among congestive heart failure (CHF) patients.

Design: A cross-lagged panel design was used.

Methods: CHF patients (N?=?142) reported twice, six months apart, on their meaning in life and the extent to which CHF violates their beliefs and goals.

Results: Overall, results were consistent with a reciprocal relationship, showing that greater goal violations led to negative subsequent changes in meaning, whereas greater meaning led to favorable subsequent changes in violations of beliefs and goals.

Conclusions: Meaning in life and violations may contribute to one another, and therefore, in understanding the adjustment process, it is important to consider their interrelationship. The results are also broadly informative regarding the experience of meaning, showing that disruption of beliefs and goals may undermine meaning.     

The perception of team engagement reduces stress induced situation awareness overconfidence and risk-taking

Much research has examined how stress restricts objective Situation Awareness (SA). Little research, however, has focused on SA overconfidence, the notion that an individual may grasp a situation when in fact they do not. Even less SA research has examined the motivational and emotional states of individuals operating in teams in stressful environments. Expanding on recent data suggesting that stress creates SA overconfidence, not simply SA loss, the present experiment manipulated stress levels and the perception of team engagement, which is thought to be a positive motivational state of task-related well-being. Teams of Soldiers were tested in a virtual combat scenario testing shared risk-taking, objective (i.e., collaborative ability to answer SA probes), and subjective SA. Results indicated that the mere perception of above average team engagement reduced stress induced SA overconfidence and risk-taking of teams. These results suggest simple, virtually costless strategies for improving elements of SA that may impact the behavior of teams and potentially improve their decision-making.     

儿童受欺负与急性社会应激中应激反应的关系

研究旨在考察受欺负经历与儿童下丘脑-垂体-肾上腺轴系统应激功能的关系。根据受欺负得分挑选出52名受欺负和未受欺负儿童,考察两类儿童在特里尔社会应激测验(Trier Social Stress Test,TSST)中的皮质醇分泌及主观紧张度的特征差异。结果发现:(1)在TSST中,受欺负者的皮质醇浓度显著高于未受欺负者;(2)两类儿童在TSST中的主观紧张度不存在显著差异。研究结果与慢性应激破坏HPA轴应激功能的过程是从敏化到钝化的理论假说相一致。     

留守儿童生活压力与孤独感、幸福感的关系:心理资本的中介与调节作用

采用问卷法对971名农村儿童进行入户调查,以考察生活压力与留守/非留守儿童孤独感、幸福感的关系以及心理资本在此关系中的作用。结果显示:与非留守儿童相比,留守儿童的生活压力与孤独感较高,心理资本与幸福感较低;生活压力对留守/非留守儿童的孤独感有正向预测性、幸福感有负向预测性,心理资本对此起部分中介作用,且在两群体中的中介过程一致;心理资本仅能有效缓冲生活压力对留守儿童孤独感、幸福感的不利影响。     

Mindful Mates: A Pilot Study of the Relational Effects of Mindfulness‐Based Stress Reduction on Participants and Their Partners

Very little is currently known about how increases in dispositional mindfulness through mindfulness training affect the quality of participants’ romantic relationships, and no previous studies have examined how increases in specific facets of mindfulness differentially contribute to relationship health. Additionally, even less is known about how an individual's development of mindfulness skills affects the relationship satisfaction of his or her romantic partner. Thus, the purpose of this pilot study was to examine associations between changes in facets of mindfulness and relationship satisfaction among participants enrolled in a Mindfulness‐Based Stress Reduction (MBSR) course and their nonenrolled romantic partners. Twenty MBSR participants and their nonenrolled partners (n = 40) completed measures of mindfulness and relationship satisfaction pre‐ and post‐enrolled partners’ completion of an MBSR course. Results indicated that enrolled participants significantly improved on all facets of mindfulness and relationship satisfaction, while nonenrolled partners did not significantly increase on any facet of mindfulness or relationship satisfaction. Moreover, enrolled participants’ increases in Acting with Awareness were positively associated with increases in their own and their nonenrolled partners’ relationship satisfaction, whereas increases in enrolled participants’ Nonreactivity were positively associated with increases in their nonenrolled partners’ (but not their own) relationship satisfaction. These results suggest that increasing levels of mindfulness (particularly specific aspects of mindfulness) may have positive effects on couples’ relationship satisfaction and highlight mindfulness training as a promising tool for education and intervention efforts aimed at promoting relational health.     

Controverse relative à la relation entre le stress et la performance au travail : recherche d’explications

Despite many efforts, the relationship between stress and performance remains very controversial. No relational assumption seems to dominate and empirical results present contradictory observations. Pursuing to clarify this relationship, this study has two objectives: countercheck the relation between stress and performance at work and document the potential moderating effects of commitment and job satisfaction on this relation. From information collected by self-administered questionnaires, the statistical analysis demonstrates the absence of relation between stress and performance in the restoration sector and a negative relation for workers in the health sector. As for the moderating properties of commitment and satisfaction, it appears that these variables do not permit to enlighten the relational ambiguities between stress and performance. The discussion presents supporting explanation to the disparity of results between samples.     

自尊与心理性应激反应的关系：社会认可需求的中介作用

国外研究者认为高自尊个体的内控性高,因此其在心理性应激情境中的反应不那么强烈,而国内研究者从集体文化(中国)考虑,则认为高自尊个体的社会认可需求较高,因此在心理性应激情境中的反应更强烈.本研究采用特里尔社会应激测试作为应激情境,采集41名中国大学生被试在这一情境下的客观参数(心率)作为心理性应激反应的指标,通过问卷测量被试的自尊水平、内控性水平和社会认可需求水平,考察自尊影响心理性应激反应的机制.结果发现被试的自尊水平与应激情境下的心率呈正相关,并且社会认可需求在自尊与心理性应激的关系中起着显著的中介作用.本文从文化差异角度提出自尊预测心理性应激反应的模型可能需要在不同文化背景下来分别探讨.
