幼儿教师职业承诺对工作绩效的影响:职业幸福感的中介作用

为探索幼儿教师职业承诺和职业幸福感对工作绩效的影响,选取川渝两地幼儿教师328名,用幼儿教师职业幸福感量表(KTOWBS)、教师职业承诺问卷(TOCQ)、教师工作绩效量表(TJPS)进行调查。结果表明:(1)控制学校性质、工作时间、每月收入、教师年龄以及教龄影响后,幼儿教师情感承诺和规范承诺分别对工作绩效有显著的积极影响,继续承诺则对工作绩效有显著的消极影响;(2)幼儿教师职业幸福感在情感承诺、规范承诺和继续承诺对工作绩效的影响中起部分中介作用。以上研究结果对保护和提高幼儿教师工作绩效具有重要理论价值和实践意义。     

工作要求-资源模型与工作倦怠的相互影响

采用间隔六个月的三波纵向设计,对国内263名企业员工的工作倦怠、工作要求、工作资源进行测量,探讨中国文化背景下企业员工工作环境的动态变化和倦怠体验的相互影响及其作用机制。研究结果表明,控制基线水平后,工作要求增量正向影响工作倦怠增量,工作资源增量负向影响工作倦怠增量;而工作倦怠增量进一步对员工所处的微工作环境产生一定的负面影响,导致工作要求进一步增加,工作资源进一步降低,因此易形成“工作环境恶化→工作倦怠加剧→工作环境进一步恶化”的恶性因果关系回路。     

Impacts of exposure to images of ideal bodies on male body dissatisfaction: a review

Research suggests that young men's body dissatisfaction increases when they see images of attractive muscular men. This article provides the first extensive review of experimental studies exposing men to advertisements or commercials featuring idealized male bodies. Impacts on body dissatisfaction were evaluated by calculating and analyzing effect sizes from 15 studies. The effect sizes indicate that exposure to images of idealized male bodies has a small but statistically significant negative impact on men's body dissatisfaction. Three studies suggest that young men who are dissatisfied with their bodies are at increased risk for negative self-evaluations when exposed to idealized images. Two studies suggest that men who are satisfied with their bodies may be protected against negative impacts from seeing such images.     

Defining body deception and its role in peer based social comparison theories of body dissatisfaction

The purpose of the current study was to operationalize the phenomenon of body deception, describe its theoretical importance, and validate its existence in an experimental paradigm. The definition of body deception includes the intentional misrepresentation of information about appearance to others. The present study examined body deception in a controlled experimental study of male and female same-sex peer groups using a series of hierarchical linear models. Ninety male and 90 female undergraduates were randomized to an experimental same-sex peer group or individual control condition. The results suggested that both men and women used body deception among peers, but men's body deception was muscularity driven whereas women's was thinness driven. Body dissatisfaction was significantly predictive of the degree of body deception used by both genders and it was significantly related to peer group membership. An integrated model for the role of body deception in body image disturbance is proposed.     

Examining body dissatisfaction in young men within a biopsychosocial framework

This study examined biopsychosocial factors related to body dissatisfaction in young men within multivariate and moderator contexts. A female sample was included as a gender comparison. Male (n = 111) and female (n = 236) undergraduates filled out self-report questionnaires assessing body mass index (BMI), media influence, a history of weight-related teasing, and socially prescribed perfectionism, along with various indices of body dissatisfaction. Perceived pressure from the media was consistently related to body dissatisfaction in men whereas multiple biopsychosocial variables accounted for body dissatisfaction in women. Socially prescribed perfectionism and a history of weight teasing each moderated the relationship between BMI and male body dissatisfaction, identifying men low in body dissatisfaction. Findings indicate that applying a biopsychosocial framework to the study of body dissatisfaction in men is useful and suggest the need for including other factors, such as male peers and sports involvement, in understanding contributors to male body image.     

Work Engagement: Investigating the Role of Transformational Leadership,Job Resources,and Recovery

While the relationship between job resources and engagement has been well established, a greater understanding of the upstream factors that shape job resources is required to develop strategies to promote work engagement. The current study addresses this need by exploring transformational leadership as an upstream job resource, and the moderating role of recovery experiences. It was hypothesized that job resources would mediate the relationship between transformational leadership and engagement. Recovery experiences were expected to moderate the relationship between resources and engagement. A sample of 277 employees from a variety of organizations and industries was obtained. Analysis showed direct relationships between: transformational leadership and engagement, and transformational leadership and job resources. Mediation analysis using bootstrapping found a significant indirect path between transformational leadership and engagement via job resources. Recovery experiences did not significantly moderate the relationship between job resources and engagement. To date, the majority of published literature on recovery has focused on job demands; hence the nonsignificant result offers insight of a potentially more complex relationship for recovery with resources and engagement. Overall, the current study extends the JD-R model and provides evidence for broadening the model to include upstream organizational variables such as transformational leadership.     

A Reanalysis of Occupation and Suicide: Negative Perceptions of the Workplace Linked to Suicide Attempts

Suicide is the ultimate outcome of poor psychological well-being; however, there is a paucity of research examining the link between occupation and suicide, despite early academic interest and the known importance of work to our everyday lives. We propose that this body of research was abandoned prematurely, and we provide a reanalysis by integrating the Job Characteristics Model and the Conservation of Resources model with extant suicide research. Specifically, we hypothesize that work design characteristics (job autonomy, task variety, physical demands) and threats to personal resources (absence of viewing work-as-career, work-family conflict, family-work conflict, job dissatisfaction) are linked to suicide attempts via depression and suicidal ideation. Utilizing three measurement occasions and 2,855 participants from the AddHealth database, our findings indicate that job autonomy, task variety, work-family conflict, family-work conflict, and job dissatisfaction all indirectly contribute to employees' suicide attempts via depression and suicidal ideation. Thus, negative employee perceptions of the workplace environment have much more severe consequences than is typically examined. Based on these results, we provide recommendations for developing a theoretically derived nomological net around suicidal behavior in an organizational context, and offer strategies for managers and employees to construct a work environment that is conducive to employee well-being.     

幼儿教师胜任力和职业压力对职业幸福感的影响:职业认同和职业倦怠的作用

为探索幼儿教师胜任力、职业压力、职业认同以及职业倦怠对职业幸福感的影响机制,选取四川、重庆、西藏、贵州和北京五地幼儿教师326名,用幼儿教师职业幸福感量表、幼儿教师胜任力问卷、幼儿教师工作压力源问卷、幼儿教师职业认同问卷和教师职业倦怠量表进行调查。结果表明：（1）控制学校性质、每月收入、教师教龄和年龄影响后,幼儿教师职业认同是胜任力提升职业幸福感的中介。（2）幼儿教师职业倦怠和职业认同是职业压力降低职业幸福感的中介,具体包括职业倦怠和职业认同的单独中介效应以及职业倦怠--职业认同的链式中介效应三条路径。（3）幼儿教师胜任力缓解职业压力对职业倦怠的影响;职业压力放大胜任力对职业认同的影响。以上研究结果拓展了职业幸福感的JD-R模型,并对提升幼儿教师职业幸福感具有重要价值。     

心理资本与工作绩效的关系:基于本土心理资本理论的视角

采用问卷调查法,以445名企业员工和MBA学员为调查对象,考察了本土心理资本与适应性绩效的关系。结果表明:(1)本土心理资本对任务绩效和周边绩效均有显著的预测作用;其中事务型心理资本对任务绩效的预测作用较强;而人际型心理资本对周边绩效的预测作用较强。(2)本土心理资本对适应性绩效有显著的正向预测作用;其中事务型心理资本主要影响了压力与应急管理、创新问题解决、岗位持续学习等维度,而人际型心理资本则主要影响了人际与文化适应和岗位持续学习等维度。(3)适应性绩效在事务型和人际型心理资本与周边绩效间起部分中介作用,在事务型心理资本与任务绩效间也起部分中介作用。(4)在控制事务型心理资本的前提下,人际型心理资本对适应性绩效和周边绩效仍有显著的预测作用,显示人际型心理资本的构念具备实证效度。
