Self‐regulation and well‐being: The influence of identity and motives

The relationship between self‐regulatory capacities and self‐esteem as well as well‐being is examined by a mediation model that views self‐regulation as promoting the development of identity achievement which, in turn, is expected to be associated with well‐being. Among secondary school students (Study 1) identity achievement mediated the association between the self‐regulatory capacity of attention control and self‐esteem. In Study 2 (university students), the mediational effect of identity achievement was found for the relationship between the self‐regulatory capacity of action control and well‐being. Explicit motives moderated this association. In sum, a firm identity enhances well‐being by lending a sense of continuity to one's life. However, explicit motives have a substitution effect by giving direction to life when lacking firm identity commitments. Copyright © 2010 John Wiley & Sons, Ltd.     

The relationship between psychological contract breach and organizational commitment: Exchange imbalance as a moderator of the mediating role of violation

This study tested the mediating role of violation in the relationship between breach and both affective and continuance commitment and the extent to which this mediating role is moderated by exchange imbalance amongst a sample of 103 sales personnel. Results suggest that violation mediated the relationship between breach and commitment. Also, results suggest that perceived exchange imbalance moderates this mediating pathway: Low exchange imbalance increases the mediating role of violation in the case of affective commitment. On the other hand, exchange imbalance failed to moderate the mediating influence of violation in the case of continuance commitment. Results are discussed in view of the importance of a) including both measures of violation and breach in future studies and b) the role of social exchange in explaining psychological contract violation.     

基于不对称区间估计的有调节的中介模型检验

有调节的中介模型是中介过程受到调节变量影响的模型。评介了基于Bootstrap不对称置信区间和贝叶斯不对称可靠区间进行有调节的中介模型检验的3种方法, 包括亚组分析法、差异分析法和系数乘积法。模拟研究发现, 偏差校正的百分位Bootstrap置信区间和无先验信息的贝叶斯可靠区间在有调节的中介模型检验中表现相当, 都优于百分位Bootstrap置信区间的表现。建议使用系数乘积法进行第一阶段或第二阶段被调节的中介模型检验, 使用差异分析法进行两阶段被调节的中介模型检验, 并用一个实际例子演示如何用不对称区间估计检验有调节的中介模型。随后评述了3种有调节的中介模型检验方法在国内心理学的应用现状, 并展望了检验的拓展方向。     

有调节的中介模型检验方法：竞争还是替补?

在心理和其他社科研究领域, 经常遇到中介和调节变量。模型的变量多于3个时, 可能同时包含中介和调节变量, 一种常见的模型是有调节的中介模型。本文检视文献上各种检验有调节的中介模型的方法, 理清方法之间是竞争关系(分清优劣)还是替补关系(分清先后), 在此基础上总结出检验有调节的中介模型的步骤, 并用一个实例进行演示。文中也讨论了有调节的中介模型与有中介的调节模型的联系与区别。     

变革型领导对员工绩效和满意度的影响：心理资本的中介作用及程序公平的调节作用

通过对国内一家企业共785位员工及其直接主管的问卷调查, 考察了下属心理资本在变革型领导与下属工作绩效及满意度之间关系的中介作用以及程序公平对该关系的调节作用。研究结果显示：1)下属的心理资本与其工作绩效和满意度正向相关; 2)下属的心理资本部分中介了变革型领导对下属工作绩效及满意度的正向关系; 3) 下属的程序公平调节了变革型领导对下属心理资本的影响。具体而言, 下属的程序公平感越高, 变革型领导与下属心理资本的正向关系越强, 反之越弱; 4) 进一步地, 程序公平调节了下属心理资本对变革型领导－工作绩效和满意度的中介作用, 即：程序公平感越高, 变革型领导通过心理资本对下属的工作绩效和满意度所产生的作用就越强, 反之越弱。最后讨论了该研究的理论意义和应用价值。     

中介效应的检验方法和效果量测量:回顾与展望

通过中介效应检验方法之间的比较和效果量指标之间的比较,建议放弃将总效应c显著作为中介效应检验的前提条件,放弃基于直接效应c'显著性的完全和部分中介的提法,推荐使用偏差校正的百分位Bootstrap法直接对中介效应ab进行检验,使用κ²、R_med²等中介效果量指标并报告效果量的置信区间。作为示例,用R软件的MBESS软件包对某消防员饮食健康调查进行了中介效应检验和效果量测量。随后展望了中介效应检验方法和效果量测量的拓展方向。     

家庭收入与青少年社会适应：家庭社会资本的中介作用

为了探讨家庭社会资本在家庭收入对青少年社会适应影响中的中介作用,选取了418名农村小学3-6年小学生作为被试,采用家庭经济压力问卷、同伴提名法、学习成绩、孤独感问卷和家庭社会资本问卷进行研究。结果表明：（1）家庭经济压力与学业成就、同伴接纳存在显著的负相关,与孤独感存在显著正相关;（2）家庭经济压力通过家庭社会资本的完全中介作用影响学业成就（中介效应值为–0.14）;（3）家庭经济压力通过家庭社会资本的完全中介作用影响孤独感（中介效应值为0.03）;（4）家庭经济压力通过家庭社会资本的完全中介作用影响同伴接纳（中介效应值为–0.07）。研究得出,家庭收入完全通过家庭社会资本来影响青少年的社会适应。     

Getting Vygotskian about theory of mind: Mediation,dialogue, and the development of social understanding

The ideas of Vygotsky [Vygotsky, L. S. (1987). Thinking and speech. In The collected works of L. S. Vygotsky, (Vol. 1). New York: Plenum. (Original work published 1934.)] have been increasingly influential in accounting for social–environmental influences on the development of social understanding (SU). In the first part of this article, I examine how Vygotskian ideas have to date been recruited to explanations of the development of SU. Next, I present a model of SU development which draws on two implications of Vygotsky’s ideas: the importance of semiotic mediation for mental functioning, and the dialogic nature of the higher mental functions. I then consider the value of the proposed model in accounting for evidence from three areas of enquiry: the typical development of SU in infancy and early childhood, relations between individual differences in SU and social–environmental variables, and atypical development. The model is suggested to be particularly helpful in understanding the transition from intentional-agent to mental-agent understanding, and the role of language in SU. Remaining challenges include a need to specify further the cognitive processes underlying internalization, and to gather more extensive evidence on the roles of typical and atypical social experience in SU development.     

Negative self-focused cognitions mediate the effect of trait social anxiety on state anxiety

The cognitive model of social anxiety predicts that negative self-focused cognitions increase anxiety when anticipating social threat. To test this prediction, 36 individuals were asked to anticipate and perform a public-speaking task. During anticipation, negative self-focused cognitions or relaxation were experimentally induced while self-reported anxiety, autonomic arousal (heart rate, heart rate variability, skin conductance level), and acoustic eye-blink startle response were assessed. As predicted, negative self-focused cognitions mediated the effects of trait social anxiety on self-reported anxiety and heart rate variability during negative anticipation. Furthermore, trait social anxiety predicted increased startle amplitudes. These findings support a central assumption of the cognitive model of social anxiety.     

基于情绪调节模型的教师情绪劳动的中介效应探讨

本研究以Grandey的情绪调节模型为框架,通过问卷调查的方法,探讨正性情绪、负性情绪、情绪劳动以及职业倦怠之间的关系。828名中小学教师的有效数据的回归分析结果显示:基于不同情绪感受的情绪劳动对职业倦怠的影响存在差异;情绪劳动各维度既充当正负情绪均值差距(M_N-P)影响职业倦怠各维度的部分中介变量,又充当正负情绪变异系数差距(CV_N-P)影响去个性化或个人成就感的部分中介变量;表层行为、深层行为在正负情绪均值差距(M_N-P)影响去个性化之间的部分中介效应受到性别的调节。
