Validation of the Life Role Salience Scale in a South African setting

This study aimed to validate the Life Role Salience Scale (LRSS) in a South African context. Respondents were 300 working adults (72.3% = women; 57.9% = non-white; mean age = 35.12 years, SD = 10.25 years; mostly from the finance sector = 35.6%). Confirmatory factor and exploratory factor analyses were conducted to determine the LRSS’s factor structure and reliability of scores from the scale for the South African sample. Results yielded five factors emerging from the analyses: Homecare role reward value and homecare role commitment; marital role reward value and marital role commitment; occupational role commitment; occupational role value reward; and parental role reward value. The reliability of scores from the LRSS ranged from 0.79 (parental role reward value) to 0.95 (homecare role reward value and homecare role commitment). The LRSS shows validity for research use in South Africa.     

基于结构方程模型的有调节的中介效应分析

有调节的中介模型是中介过程受到调节变量影响的模型。指出了目前有调节的中介效应分析普遍存在的问题：当前有调节的中介效应检验大多使用多元线性回归分析,忽略了测量误差;而基于结构方程模型(SEM)的有调节的中介效应分析需要产生乘积指标,又会面临乘积指标生成和乘积项非正态分布的问题。在简介潜调节结构方程(LMS)方法后,建议使用LMS方法得到偏差校正的bootstrap置信区间来进行基于SEM的有调节的中介效应分析。总结出一个有调节的中介SEM分析流程,并有示例和相应的Mplus程序。文末展望了LMS和有调节的中介模型的发展方向。     

Renegotiating Identity: A Phenomenological Investigation of the College Transition for Former High School Athletes No Longer Engaged in Varsity Competition

A breadth of research has examined the influence of athletic identity on college student-athlete experiences (e.g., Harrison et al., 2011; Lally & Kerr, 2005). In addition, scholars have investigated role transition among college student-athletes at the end of their eligibility (e.g., Taylor & Ogilvie, 2001; Wylleman & Lavallee, 2004). However, despite that 97% of high school athletes will not participate collegiately (National Collegiate Athletic Association, 2016), little attention has been paid to identity renegotiation among college students who discontinued sport participation after high school. The present study was designed to fill this gap by addressing the impact of sport disengagement on former high school athletes no longer engaged in varsity competition during the first year of college. In-depth, semi-structured interviews were conducted with 13 university freshmen at three time points: the end of the first month, the end of the first semester, and the end of the first year. Commonalities among participants’ transition experiences were identified. Findings yielded three major themes, role transition, identity renegotiation, and reflection and projection, each being facilitated by the building of camaraderie. Findings deepen current understanding of role transition and identity renegotiation and offer directions for future research related to sense of self during the college transition.     

青少年公正世界信念对抑郁的影响:感恩和自尊的序列中介作用

为探讨青少年公正世界信念与抑郁的关系,以及感恩和自尊在二者关系中的作用机制,采用公正世界信念问卷(BJW)、感恩问卷(GQ-6)、自尊量表(SES)和流调中心用抑郁量表(CES-D)对1049名高中学生进行调查。结果发现:(1)青少年公正世界信念、感恩和自尊两两之间呈显著正相关,且三者均与抑郁呈显著负相关。(2)青少年公正世界信念通过感恩和自尊的中介作用对抑郁产生影响,且该中介效应包含了三条中介路径——感恩的简单中介效应,自尊的简单中介效应,以及感恩→自尊的链式中介作用。研究结果揭示了青少年公正世界信念对抑郁产生影响的内部心理机制,为引导青少年更好地利用公正世界信念提升感恩和自尊的水平以及更好地促进心理健康发展提供了有益建议。     

Transformational leadership and team performance in sports teams: A conditional indirect model

This study tests how transformational leadership fosters team performance through team cohesion and how that relationship is moderated by previous team performance and leadership consensus. We computed a moderated-mediation model based on a sample of 690 professional players in 59 top professional teams in interactive team sports leagues (basketball, handball, roller hockey, and indoor football/soccer) in Spain. Our findings suggest that transformational leadership indirectly influences objective team performance through the mediation role of team cohesion and that this indirect effect is more prominent when the level of previous performance is higher. We also found that the indirect effect of transformational leadership on team performance via cohesion is stronger in teams with higher consensus regarding their coaches' leadership. Overall, our results demonstrate the importance of integrating dispersion and contextual variables into research models, in particular, previous performance and leadership consensus.     

基于正则化的探索性中介分析:原理与应用

探索性中介分析被定义为从变量集合中筛选潜在中介变量的方法,该方法能在缺乏理论基础的情况下帮助研究者从数据中挖掘潜在中介机制,提供模型构建上的指导。本文介绍了一种基于正则化的探索性中介分析方法XMed(exploratory mediation analysis via regularization)。相比于传统探索性中介分析方法,XMed具有检验力更高、所需样本量更小、能高效地处理高维数据等优点,在认知神经科学、临床心理学等心理学领域有较大的应用潜力。本文主要介绍XMed的原理和实现过程,并通过实例分析展示该方法的应用。

Social‐cognitive mediators of the relation of environmental and emotion regulation factors to children's aggression

Tested a theoretical model in which social cognitions about aggression partially mediated the relation of environmental and emotion regulation factors to children's aggressive behavior. An ethnically diverse sample of 778 children (57% girls) in grades 4–6 from both urban and suburban schools participated. Measures included exposure to aggression (seeing/hearing about aggression, victimization), emotion regulation (impulsivity, anger control), social cognitions about aggression (self‐evaluation, self‐efficacy, retaliation approval, aggressive fantasizing, caring about consequences), and aggressive behavior. Results supported the hypothesis that social cognitions mediate the relations of exposure to aggression and anger control to aggressive behavior. Also, social cognitions about direct and indirect aggression differentially predicted the respective behaviors with which they are associated. That is, social cognitions about direct aggression were mediators of direct aggressive behavior, whereas social cognitions about indirect aggression were mediators of indirect aggressive behavior. Finally, gender moderated the relations among the variables such that for girls, retaliation approval beliefs were a strong mediator, whereas for boys, self‐evaluation was more important. Aggr.
