新冠疫情期间中小学教师工作-家庭冲突和抑郁:有调节的中介模型

本研究考察新冠疫情期间,工作-家庭冲突是否通过职业倦怠增加中小学教师抑郁水平,以及心理弹性是否调节该中介作用。1127名中小学教师参与线上调查,完成中小学教师工作-家庭冲突问卷、中小学教师职业倦怠问卷、抑郁自评量表及中学教师心理弹性量表。结果发现：(1)大多教师疫情前后工作生活情况、工作-家庭冲突与抑郁的状况变化不大,少数教师疫情期间工作生活情况、工作-家庭冲突与抑郁状况变差或好转;(2)教师工作-家庭冲突与抑郁、职业倦怠呈正相关,三者均与心理弹性负相关;(3)控制额外变量后,职业倦怠是工作-家庭冲突与抑郁间的中介变量,在疫情期间工作生活状态更好、更差以及与疫情前后没有差别的教师中均成立;(4)对于感知疫情后情况更好的教师,心理弹性调节了工作-家庭冲突与职业倦怠的关系。对于感知疫情后情况更差的教师,心理弹性调节了职业倦怠与抑郁的关系。因此,缓解工作-家庭冲突和职业倦怠、提高心理弹性可减少中小学教师抑郁,保持心理健康。     

秒回?信息通讯技术时代的职场通讯压力

职场通讯压力是指员工想要快速回复基于信息通讯技术(information and communication technology, ICT)的工作消息而体验到的紧迫性, 现有研究对其成因及影响路径的探讨较为零散且缺乏系统性认识。基于工作要求-资源模型并结合努力-恢复模型, 讨论作为工作要求的ICT使用以及作为个人要求/资源的个体因素对职场通讯压力的前因作用; 探讨职场通讯压力因阻碍恢复活动而对员工身心健康以及工作和家庭领域产生的消极影响, 以期增进对职场通讯压力的全面了解, 丰富现有研究对ICT使用后果的认识, 并为未来研究的展开以及员工职业心理健康干预实践提供参考。     

职业乐观对组织承诺、求职行为的影响:有调节的中介模型

职业乐观是影响个体职业适应的重要因素之一。尽管以往文献大多认为职业乐观是有利的,然而职业乐观的个体也会出现求职行为,导致对现有工作的专注程度降低的负面影响。为了探讨职业乐观的双刃剑效应及其边界条件,通过2个时间点问卷调查法对581名企业员工进行调查,结果发现:(1)职业乐观对求职行为和组织承诺均有正向影响;(2)易变职业生涯定向在职业乐观对求职行为影响中起中介作用,工作归属感在职业乐观对组织承诺影响中起中介作用;(3)心理授权在职业乐观对易变职业生涯定向的影响中起负向调节作用,在职业乐观对工作归属感的影响中起正向调节作用。     

资源保存理论在组织行为学中的应用：演变与挑战

资源保存理论(conservation of resources theory, COR)是组织行为学研究近30年中被引最高的理论之一。COR的提出源自Hobfoll对临床应激障碍的观察与思考,历经了多次修订后该理论逐步由一个压力–反应模型发展成了一个以个体资源存量及其动态变化解释行为动因的动机理论,形成了一个具有较广泛外延的理论体系。组织行为学是资源保存理论标志性文献的施引文献的核心来源。大量组织行为学研究对COR中的资源损失漩涡、获得螺旋等核心过程进行了实证检验,涉及广泛的研究议题,使COR成为了理解员工心理与行为动因的最具影响力的理论之一。COR在组织行为学中的应用面临一定的挑战,其中有来自认知评价理论、适应理论的观点挑战,也有其作为一个\"跨界理论\"带来的挑战。组织行为学研究在应用COR时应充分尊重其理论要义,避免削足适履。     

居危思变?工作不安全感对创新行为的差异化影响?

企业往往在员工管理和组织创新上处于“两难困境”——难以提供稳定工作但又不得不依赖员工实现组织创新, 这就使得研究员工工作不安全感对创新行为的影响至关重要。企业员工遭遇不同环境威胁带来的工作不安全感时, 创新行为存在差异。本文在威胁焦点下深化工作不安全感概念, 并基于“以变量为中心”和“以人为中心”的研究思路, 探讨其对创新行为的差异化影响过程。首先, 结合环境威胁来源与主观感知, 把工作不安全感分为岗位焦点工作不安全感和人员焦点工作不安全感两个维度, 并将编制测量量表。其次, 期望运用纵向研究设计, 通过分析多时点的员工-主管配对数据, 基于情境调节焦点和工作激情的链式中介作用, 来揭示岗位焦点工作不安全感对创新行为的负向影响, 以及人员焦点工作不安全感对创新行为的倒U型影响。最后, 将采取“以人为中心”的研究思路, 运用潜在剖面分析方法探讨工作不安全感潜在类型及其对创新行为的影响。研究结果将有助于推进工作不安全感的概念和效用研究, 也为企业如何有效促进创新提供对策建议。     

Effects of exposure to muscular and hypermuscular media images on young men's muscularity dissatisfaction and body dissatisfaction

This study examined the effects of exposure to muscular and hypermuscular media images on young men's body images, and the moderating roles of baseline body dissatisfaction (BD) and muscularity dissatisfaction (MD). Men (M age = 21.9, SD = 2.8) were exposed to pictures of muscular (n = 34) or hypermuscular (n = 29) male physiques throughout a 30-min health seminar. In support of the study hypotheses, higher levels of baseline BD and MD were associated with greater post-seminar BD and MD. In addition, MD moderated the effects of the exposure conditions on BD; greater baseline MD was associated with greater post-seminar BD, but only among men who viewed the muscular images. These results speak to the importance of pre-existing muscularity concerns in determining men's reactions to muscular physique images, and suggest that exposure to the media ideal of muscularity, and not muscularity per se, elicits body dissatisfaction in men with pre-existing muscularity concerns.     

The job demand-control(-support) model and physical health outcomes: A review of the strain and buffer hypotheses

Abstract

This review of the Job Demand-Control (JDC) model and the expanded Job Demand-Control-Support (JDCS) model and employees' physical health, focuses on the two prevalent views on these models. According to their view on the models researchers study different hypotheses: (a) the (iso)strain hypothesis, stating that the highest level of ill health is expected when the job is characterized by high demand and low control (and low social sup port), ot (b) the buffer hypothesis, predicting that control (and social support) can buffer the potential negative effects of high demands on physical health. It is argued that these hypotheses reflect theoretical distinct models, and that the practical implications associated with these models differ.

The review of 51 studies on the JDC(S) model reveals that the “strain” hypothesis predominates in studies of all-cause mortality, cardiovascular disease (CVD) related and specific non-CVD related health outcomes. In contrast, the “buffer” hypothesis is most prevalent in research on self-reported (psycho)somatic complaints. For the strain hypothesis as well as the buffer hypothesis the results are equivocal. Working in a high (iso)strain job appears to be associated with an elevated risk for cardiovascular disease and negative pregnancy outcomes, and increased (psycho)somatic complaints. Conclusions on other physical outcomes seem premature, considering the limited number of studies. The buffer hypothesis is supported in the few studies on CVD endpoints and in some studies on (psycho)somatic complaints.

A comparison of the validity of the two hypotheses is problematic, because they are mostly applied to a different set of outcomes. Furthermore, the analyses employed in the testing of the two hypotheses are of a different nature (non-linear versus linear).

The main recommendation for future research is to examine the validity of the strain and the buffer hypothesis concurrently, and to further explore the nature of the relationships.     

Effects of lifestyle and stress on the employee and organization: Implications for promoting health at work

Abstract

This research was designed to determine the extent to which employee health and performance are predicted by lifestyle and stress. Data were collected from 345 employees working in a variety of organizations in southern California. Additionally, supervisors evaluated the work performance of the participating employees whom they directly supervised, and company records of employee health care costs were obtained. Hierarchical multiple regression analyses revealed (a) that physical lifestyle (i.e., exercise pattern, eating habits, and general health practices) predicted unique variance in vitality and positive well-being; (b) that psychosocial lifestyle (i.e., social relations, intellectual activity, occupational conditions, and spiritual involvement) predicted unique variance in vitality, positive well-being, anxiety, depression, lack of self-control, and somatic complaints; (c) that employee stress predicted unique variance in vitality, positive well-being, anxiety, depression, physician visits, somatic complaints, illness absences, and supervisory ratings of job performance, absenteeism and tardiness; (d) that physical lifestyle buffered the adverse consequences of stress for anxiety, depression, physician visits, and company health care costs; and (e) that there was a Physical x Psychosocial Lifestyle interaction for anxiety, depression, and lack of self-control. However, the employee lifestyle factors were not related to supervisory ratings of performance at work. The findings have direct implications for organizational health programs and policies.     

Having the will and finding the way: A review and meta-analysis of hope at work

Critics of the field of positive organizational psychology have expressed reservations with validity and utility of positive constructs, such as hope. The purpose of this article is to systematically review the existing research on hope at work and to determine the ‘true’ relationship between hope and work outcomes by meta-analyzing 133 effect sizes across 45 primary studies based on 11,139 employees. As predicted, we found that the overall corrected mean effect sizes between hope and work performance and employee well-being were positive and statistically significant. Gender and study location were significant moderators of these relationships, with women and US-based studies having stronger hope to work outcomes effects. Taken together, results demonstrate that positive psychology constructs, such as hope, play an important role in understanding and predicting employee behavior.     

Psychological Hardiness and Adjustment to Life Events in Adulthood

Data were collected from 88 persons who had lost their jobs and 227 persons whose youngest child had left home to explore the impact of psychological hardiness on personal distress, adjustment, and coping strategies. Analyses controlling for numerous sociodemographic factors as well as NEO Neuroticism and Extroversion suggested that the interaction between overall hardiness and the experience of differential life events influenced the use of planful problem solving and positive reappraisal as coping mechanisms, as well as influencing levels of positive affect. In addition, a main effect for overall hardiness on several coping strategies, positive affect, and life satisfaction was obtained. Findings also suggested that job loss was a more stressful experience for adults in this study than was the empty nest. These data indicate that hardiness may mediate responses to life events that differ in terms of their predictability and anticipatory nature.
