Understanding The Curvilinear Relationships between LMX Differentiation and Team Coordination and Performance

The leader–member exchange (LMX) literature argues that leaders develop different quality dyadic relationships with members in the same team (i.e., LMX differentiation). Research has generally not found support for a linear (i.e., main effect) relationship between LMX differentiation and team performance; rather, moderators typically determine whether the relationship is significantly positive or negative. Examining linear effect moderators alone, however, does not account for (a) potential curvilinear (i.e., inverted U‐shaped) effects, (b) explanatory mechanisms of how LMX differentiation influences team performance, or (c) moderators of curvilinear effects. Integrating social identity theory with LMX differentiation research, we propose inverted U‐shaped relationships between LMX differentiation and both team coordination (as a mediator) and team performance (as an outcome), and we examine both team size and team power distance orientation as moderators. Using data from 928 employees in 145 teams in 3 organizations, we found an inverted U‐shaped relationship between LMX differentiation and team coordination, which, in turn, partially mediated LMX differentiation's inverted U‐shaped relationship with team performance. Larger teams, or those with higher team power distance orientation, benefit more from LMX differentiation. By integrating social identity theory with LMX differentiation research, we enhance the understanding of the processes by, and conditions under, which LMX differentiation affects team performance both positively and negatively.     

Personality in teams: Its relationship to social cohesion,task cohesion,and team performance

This study continued past research on the relationship between personality composition in teams and social cohesion and team performance (Barrick, Stewart, Neubert, & Mount, 1998). Results from the Barrick et al. sample (N = 50) were compared with data from two new samples, one comprising drilling teams in the US (N = 24), and the other comprising student teams in The Netherlands (N = 25). Furthermore, this study examined the relationship between personality composition and task cohesion, usually considered to be a stronger predictor of team performance than social cohesion. Results partly confirmed the relationships between personality composition, cohesion, and team performance that were found previously. Minimum levels of conscientiousness and agreeableness contributed positively to both task cohesion and team performance. High mean levels of extraversion and emotional stability contributed positively to social cohesion. Some results differed across the three samples, stressing the importance of task characteristics as a factor influencing relationships between team personality, team processes, and team performance. Although significant relationships were found between social cohesion, task cohesion, and performance, cohesion measures did not mediate relationships between personality composition and team performance.     

A multiplex view of leadership structure in management teams

In the hope of complementing the structural perspective in upper echelon research and advancing a fine-grained understanding of dyadic leadership influence in management teams, the current study combines two types of intrateam structures—leadership network and friendship network—to create a multidimensional conceptualization of leadership structure in management teams. Specifically, we propose that management teams with a denser singular leadership network (i.e., a network consisting of many leadership ties that are not coupled with friendship ties) should have lower management team cohesion, which subsequently renders worse business unit performance. To contrast, management teams with a denser multiplex network (i.e., a network consisting of many leadership ties that are coupled with friendship ties) should have higher management team cohesion, which subsequently renders better business unit performance. Guided by structural contingency perspective, we further propose that management team task interdependence will strengthen team cohesion's positive impact on business unit performance. To test the hypothesized model, we collected team-level social network data and multiple-wave survey data from 697 managers nested in 148 hotels (i.e., 148 management teams) owned by a large hospitality company. We also obtained objective performance data for each hotel (i.e., occupancy percentage rate and revenue per available room per day) as the criterion measure. The data supported our hypotheses. The theoretical and practical implications of our findings are discussed.     

A MULTILEVEL INVESTIGATION OF LEADER– MEMBER EXCHANGE,INFORMAL LEADER EMERGENCE,AND INDIVIDUAL AND TEAM PERFORMANCE

This study examines the antecedents and outcomes of informal leader emergence in work teams. Drawing upon research in vertical and shared leadership, we hypothesized that the relationship between leader‐‐member exchange (LMX) quality and employees’ emergence as informal leaders is moderated by team shared vision such that there is a positive (negative) LMX—leader emergence relationship for teams with high (low) shared vision. Informal leader emergence, in turn, was expected to relate to higher individual and team performance. Results based on multisource and multimethod data collected at 3 points in time (361 followers in 74 work teams) provided support for these hypotheses. The findings highlight the role played by formal leaders and team shared vision in jointly promoting or inhibiting informal leader emergence and thereby impacting individual performance and team effectiveness.     

Antecedents and Consequences of Creativity in Teams: When and How Leader Humility Promotes Performance via Team Creativity

The antecedents of team creativity and their effects on team task performance are explored in this study, with a particular focus on how leader humility promotes team creativity and when team creativity can be converted into performance. Hypotheses were tested via a multiple-source and time-lagged study with 341 employees and 104 teams from five different organizations in China. The results showed that leader humility promotes team creativity through team creative efficacy, and leader conscientiousness moderates this indirect effect. Furthermore, team creativity is more positively related to team task performance when teams are more future oriented. The theoretical contributions and management significance of these findings are discussed, followed by a discussion of limitations and directions for future research.     

团队断裂带对团队绩效的影响：团队交互记忆系统的作用

对团队构成与团队绩效关系的认识有助于充分利用团队结构优势、提高团队效能、建立竞争优势。理论界对团队断裂带与团队绩效的关系给予了极大关注, 然而遗憾的是, 研究结果还存在较大分歧。通过明确团队断裂带的属性类别, 探索团队断裂带与团队绩效之间的中介机制, 试图系统解释分歧产生的原因。基于115个实际工作团队配对样本数据的结构方程模型分析表明, 信息相关断裂带通过提高团队交互记忆系统水平促进团队绩效; 社会属性断裂带与团队交互记忆系统或团队绩效都无显著关系。本研究结果有助于深化对团队断裂带内涵及效能机制的认识, 推动团队断裂带理论的发展。     

Testing relations between group cohesion and satisfaction in project teams: A cross-level and cross-lagged approach

Based on a two-dimensional perspective of group cohesion, this study examines the emergence of task cohesion and interpersonal cohesion in project teams and their roles in changes in members’ individual satisfaction with the team. Specifically, we tested a direct-effect and mediation model of the cross-level relationship between team task and interpersonal cohesion and individual satisfaction with the team over time. With a sample of 74 newly created project teams, the hypotheses were tested using a two-wave panel design. Results indicate that task cohesion emerges more strongly than interpersonal cohesion during the first stages of work in project teams. Moreover, the cross-lagged relationship between team interpersonal cohesion and individual satisfaction with the team was mediated by team task cohesion.     

领导集权度与团队成员交换：任务互依性与团队绩效压力的调节作用

从情感互动视角出发,通过三个时间节点对72个团队的问卷调查,探讨了领导集权度对团队成员交换（TMX）及团队绩效的作用机制和边界条件。结果表明：任务互依性和团队绩效压力调节了领导集权度与TMX间的关系,即任务互依性或团队绩效压力越高,领导集权度与TMX之间的负向关系越弱,反之则越强。进一步分析显示,任务互依性和团队绩效压力调节了TMX在领导集权度和团队绩效间关系的中介作用,表现为被调节的中介作用模型。     

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.

Embracing transformational leadership: team values and the impact of leader behavior on team performance

The authors investigated the relationship between transformational leadership behavior and group performance in 218 financial services teams that were branches of a bank in Hong Kong and the United States. Transformational leadership influenced team performance through the mediating effect of team potency. The effect of transformational leadership on team potency was moderated by team power distance and team collectivism, such that higher power distance teams and more collectivistic teams exhibited stronger positive effects of transformational leadership on team potency. The model was supported by data in both Hong Kong and the United States, which suggests a convergence in how teams function in the East and West and highlights the importance of team values.     

Work-to-Life Spillover Effect of Leader–Member Exchange in Groups: The Moderating Role of Group Power Distance and Employee Political Skill

While prior studies have focused on the effect of leader–member exchange (LMX), representing a dyadic differentiated exchange relationship between a leader and followers, on employees’ job-related outcomes, how LMX at the group level influences one’s life domain has been ignored. The present study shifted attention to the relationship between LMX mean and employee life satisfaction as well as the boundary conditions. Using a sample of 471 employees from 53 groups and hierarchical linear modeling, we examined the cross-level main effect of LMX mean on life satisfaction and the moderation of group power distance and individual political skill. The results revealed that LMX mean had a work-to-life spillover effect on employee life satisfaction. Employee political skill positively moderated the relationship between LMX mean and life satisfaction, whereas group power distance negatively moderated the relation. Theoretical and practical implications were further discussed.     

Foreign Language Training Transfer: Individual and Contextual Predictors of Skill Maintenance and Generalization

Foreign language proficiency is a critical skill in which many U.S. military personnel receive extensive training. However, very little research has examined the factors associated with the successful transfer of this training. This study therefore investigates the impact of individual and contextual variables on two different types of foreign language skill transfer measures in a military context. Archival data were analyzed from 133 U.S. Army Special Forces (Green Berets) teams, including 919 Soldiers who had completed job-required foreign language training. Results indicate that initial skill acquisition had a positive impact on both the maintenance and generalization of language skills. The posttraining time interval between training and transfer measurement was negatively associated with skill maintenance, suggesting significant skill decay over time. The team context also accounted for significant variability in skill transfer, and the team mean skill level moderated the relationship between individual initial skill and subsequent generalization to job performance.

权力层级与团队绩效关系：权力与地位的一致与背离

本研究致力于探讨在权力与地位不一致的背景下, 权力层级与团队绩效研究的分歧。本研究提出权力层级与团队绩效的关系取决于团队的层级一致性——权力与地位的匹配度。具体地, 当层级一致(权力与地位匹配)时, 权力层级促进团队绩效; 当层级不一致(权力与地位不匹配)时, 权力层级抑制团队绩效。本研究结合问卷、实验和二手数据方法来验证假设, 研究1通过对46个大学生创业实践团队的两阶段问卷调查, 发现层级一致性对权力层级与团队绩效的关系具有调节作用。此后, 研究2通过一项涉及64个团队的实验来揭示因果关系, 发现权力争夺在权力层级和层级一致性的交互与团队绩效的关系中起中介作用。最后研究3通过203个观测值的互联网公司二手数据重复验证了层级一致性的调节作用, 并提升了本研究的生态效度。本研究为权力层级的研究做出了一定的贡献, 并为团队管理提供了启示。     

Selection in Teams: An Exploration of the Teamwork Knowledge,Skills, and Ability Test

In 1994, Stevens and Campion introduced the Teamwork Knowledge, Skills, and Ability test (teamwork KSA test) for selecting employees for team–based organizations. Using experimental data from 57 ad hoc student teams (N = 227), we examined this test's relationship with both the behavior of the assigned leader in a team and the behavior of the other team members, respectively. We found that the teamwork KSA test successfully predicted individual team member behavior as indexed by external raters (r= .31) and peers (r= .34) such that higher scores on the teamwork KSA test related to greater individual effectiveness within the team. The teamwork KSA test was unrelated to the behavior of the assigned leader in the teams studied. Self–efficacy for teamwork was not related to individual behavior in teams, nor did it moderate the relationship between the teamwork KSA test and individual performance in teams. Limitations as well as directions for future research in team selection are discussed.     

When does gender diversity enhance team performance? The dual need for visionary leadership and team tenure

Teams in organizations are becoming more gender diverse as women continue to participate more in the workforce than ever before. Prior theory and research indicate that the characteristics of the team influence whether gender diversity in a team is an asset or a detriment. As such, this research explores a contingency model of the relation between gender diversity and team performance and looks to understand conditions that make this relation positive or negative. Specifically, we examine how leader vision communication (i.e., visionary leadership) affects the relation between gender diversity and team performance. Results from a sample of 595 full-time employees across 106 teams in China indicate that leader vision communication moderates the relation between gender diversity and team performance such that when leader vision communication is low gender diversity decreases team performance and when leader vision communication is high gender diversity has no significant relation with team performance. We also test whether team tenure changes this relationship. Our results suggest that gender diversity improves team performance when both leader vision communication and team tenure are high. The findings in our sample demonstrate that gender diversity can help teams enhance performance, but only when the conditions are right for gender-diverse teams to flourish.     

团队权力分布差异对团队冲突的影响：程序公平和合法性的作用

近年来团队权力分布差异与团队冲突间关系受到了学界较大关注, 但相关研究结果仍存在分歧。通过对70个工作团队的调查, 探讨了团队权力分布差异对团队冲突(任务冲突、关系冲突)作用的边界条件。结果发现, 程序公平调节了两者间关系：当程序公平较高时, 团队权力分布差异与任务冲突、关系冲突负相关; 当程序公平较低时, 团队权力分布差异与任务冲突、关系冲突正相关。此外, 被中介的调节模型分析显示, 团队合法性感知中介了程序公平的上述调节作用。     

The impact of virtuality on team effectiveness in organizational and non-organizational teams: A meta-analysis

We meta-analytically assess the virtuality-team effectiveness relationship using 73 samples of organizational teams (5738 teams) reporting on a wide range of productive (e.g. earnings), performance (e.g. customer ratings), social (e.g. cohesion), and team member (e.g. project satisfaction) outcomes. Our results suggest that in work organizations, virtuality is not a direct input—negative or positive—to team effectiveness. In contrast, using 109 samples of non-organizational teams (5620 teams), we show that virtuality is a significant negative input to team effectiveness. We also meta-analytically assess the issue of results generalizability from non-organizational to organizational settings, and find that overall, results from non-organizational studies largely fail to generalize to organizational virtual teams. Using moderator analysis, we explore a number of study features that may explain the poor results generalizability from non-organizational to organizational studies. We find that results from non-organizational studies using undergraduate students, short team duration, and laboratory settings drive the non-generalizability effect, whereas results from non-organizational studies using graduate students, longer team duration, and classroom settings produce results comparable to those of organizational studies of virtual teams. Theoretical, methodological, and practical implications are discussed.     

A prospective multilevel examination of the relationship between cohesion and team performance in elite youth sport

The purpose of the current research was to (a) develop and establish the factor structure of the Czech and Slovak versions of the Youth Sport Environment Questionnaire (YSEQ; Eys, Loughead, Bray, & Carron, 2009) and (b) examine the relationship between team performance and cohesion with a sample of European elite youth sport teams. At time point one, with 352 elite youth athletes from 22 teams, support was obtained for a two factor structure underlying the YSEQ. Based on data collected at the second (N = 291) and third (N = 246) time points, multilevel analyses revealed that, when controlling for midseason cohesion, midseason team performance significantly and positively predicted task and social cohesion later in the season. Neither task nor social cohesion predicted team performance. In addition to adapting the YSEQ for use in a unique context, these findings reveal the nature of the cohesion-performance relationship in elite youth sport.
