Supervisor undermining and driving errors in truck drivers: A moderated mediation model

The present study focuses on the detrimental impact of supervisor undermining behaviors at work on driving errors for truck drivers, arguing for the mediating role of burnout. Moreover, this research highlights the moderating role of general self-efficacy in the relationships between supervisor undermining and burnout, and between burnout and driving errors, respectively. The data collected from a sample of 190 Romanian drivers supported a moderated mediation model in which burnout partially mediates the relation between supervisor undermining and driving errors, while self-efficacy moderates both aforementioned relationships. The conditional indirect effect of supervisor undermining on driving errors was significant when self-efficacy was low and non-significant when self-efficacy was high. Overall, our results emphasize the negative impact that supervisor undermining and burnout have on driving errors, while also highlighting the buffering effect of self-efficacy.     

Using video-supported reflection in peer groups to increase instructional effectiveness

This article reports upon the findings of research that explored change in teachers’ reflective thought and practice on a core set of complex teaching practices after the teachers participated in video-supported reflection model. Five 4th–7th grade teachers participated in the model that paired video-supported collaborative reflection with a research-based observation instrument, Classroom Assessment Scoring System (CLASS). Classroom observation data was collected by video and scored to determine change in teaching practice. All video-supported collaborative dialogue sessions between peers were videotaped and transcribed. Findings point to the developmental process necessary when learning to critically reflect upon and enact complex instructional practices that are not already prominent in practice. Individual development of practice progressed as the collaborative dialogue group expanded their capacity for describing, understanding, and evaluating practice based upon a new schema of effective practice, intentionally enacting change resulting in significant increases in teacher performance.     

Self-compassion mediates the link between dependency and depressive symptomatology in college students

Depression is highly prevalent among college students and is associated with significant morbidity and mortality. Dependency is among the known personality traits that predict an elevated risk for depression. Prior research has focused on the depressogenic role of self-critical thoughts among destructive overdependent (DO) individuals but has not considered other internal processes (such as self-compassion) that might influence mental health. The current report examined whether self-compassion had either moderating or mediating effects on the links between dependency and depression in college students. In a cross-sectional study, 85 college students completed measures of dependency, self-compassion, and depressive symptoms. Analyses suggested that self-compassion mediated both the effect of DO on depressive symptoms and the effect of healthy dependency (HD) on lower depressive symptoms; self-compassion did not moderate links between dependency and depressive symptoms. Our exploratory findings suggest that positive self-schema (in the form of self-compassion) may contribute to the downstream mental health effects of both adaptive HD and maladaptive DO.     

青少年偏差行为的同伴选择和影响效应:基于纵向社会网络的元分析

以22篇纵向社会网络分析研究文献(30项独立样本研究,27746个被试)为对象,使用元分析技术探讨青少年偏差行为的同伴选择和同伴影响效应假设。结果发现:(1)同伴选择和同伴影响效应都显著,但同伴影响效应显著大于同伴选择效应;(2)青少年发展阶段在同伴选择和同伴影响过程中存在显著的调节效应。在同伴选择过程中,青少年早期阶段不显著,而中、晚期阶段显著;在同伴影响过程中,青少年早、中期显著,晚期阶段不显著。(3)偏差行为类型在同伴选择和同伴影响效应中的调节效应不显著。(4)网络数量在同伴影响过程中存在显著的调节效应,随着网络数量增加同伴影响效应越可能成立。结论,中晚期青少年会基于偏差行为相似性选择朋友,早中期青少年会受朋友的影响而产生偏差行为。     

青少年抑制控制与同伴拒绝:身体攻击、关系攻击的中介作用

选取1589名青少年(平均年龄15.22±0.36岁)为被试,考察身体攻击、关系攻击在抑制控制与同伴拒绝间的中介作用。结果发现,(1)抑制控制与身体攻击、关系攻击、同伴拒绝之间均存在显著负相关,身体攻击、关系攻击与同伴拒绝之间存在显著正相关;(2)身体、关系攻击在抑制控制与同伴拒绝之间发挥中介作用;相比关系攻击,身体攻击的中介效应更强。该结果表明抑制控制对于同伴拒绝的作用既存在直接效应,又可通过身体攻击、关系攻击的中介效应实现,身体攻击、关系攻击的中介效应存在差异。     

Emotional intelligence and job performance: The mediating role of work-family balance

In this study, we examine the dynamics between emotional intelligence, work-family balance, and job performance. A review of the literature to date has shown distinct relationships between emotional intelligence to job performance and work-family balance to job performance. We utilize a sample of 233 respondents to empirically test our set of hypotheses that contend work-family balance mediates the relationship between emotional intelligence and job performance. Our results support these hypotheses. Practical implications and directions for future research are discussed.     

Experimental Power for Indirect Effects in Group-randomized Studies with Group-level Mediators

Mediation analyses have provided a critical platform to assess the validity of theories of action across a wide range of disciplines. Despite widespread interest and development in these analyses, literature guiding the design of mediation studies has been largely unavailable. Like studies focused on the detection of a total or main effect, an important design consideration is the statistical power to detect indirect effects if they exist. Understanding the sensitivity to detect indirect effects is exceptionally important because it directly influences the scale of data collection and ultimately governs the types of evidence group-randomized studies can bring to bear on theories of action. However, unlike studies concerned with the detection of total effects, literature has not established power formulas for detecting multilevel indirect effects in group-randomized designs. In this study, we develop closed-form expressions to estimate the variance of and the power to detect indirect effects in group-randomized studies with a group-level mediator using two-level linear models (i.e., 2-2-1 mediation). The results suggest that when carefully planned, group-randomized designs may frequently be well positioned to detect mediation effects with typical sample sizes. The resulting power formulas are implemented in the R package PowerUpR and the PowerUp!-Mediator software (causalevaluation.org).     

Big Five traits and relationship satisfaction: The mediating role of self-esteem

This study examined the mediating role of self-esteem in the association between Big Five traits and relationship satisfaction. Using data of 237 heterosexual couples and the Actor-Partner Interdependence Mediation Model (APIMeM), self-esteem mediated the association between Big Five traits and relationship satisfaction. We also tested the directionality of the association using longitudinal data of 141 couples. Results indicate that only agreeableness (and neuroticism marginally) predicts relationship satisfaction two years later, but relationship satisfaction predicted partner’s extraversion. Further, significant indirect effects emerged between relationship satisfaction, self-esteem, and later neuroticism. These results underline the importance of studying Big Five traits and self-esteem conjointly when studying relationship satisfaction. Furthermore, testing for alternative longitudinal associations elucidates the role of romantic relationships in personality development.
