Advice networks in teams: the role of transformational leadership and members' core self-evaluations

This article examines the team-level factors promoting advice exchange networks in teams. Drawing upon theory and research on transformational leadership, team diversity, and social networks, we hypothesized that transformational leadership positively influences advice network density in teams and that advice network density serves as a mediating mechanism linking transformational leadership to team performance. We further hypothesized a 3-way interaction in which members' mean core self-evaluation (CSE) and diversity in CSE jointly moderate the transformational leadership-advice network density relationship, such that the relationship is positive and stronger for teams with low diversity in CSE and high mean CSE. In addition, we expected that advice network centralization attenuates the positive influence of network density on team performance. Results based on multisource data from 79 business unit management teams showed support for these hypotheses. The results highlight the pivotal role played by transformational leadership and team members' CSEs in enhancing team social networks and, ultimately, team effectiveness.     

Positive Group Affective Tone and Team Creative Performance and Change‐Oriented Organizational Citizenship Behavior: A Moderated Mediation Model

Despite the vast amount of research on creativity and organizational citizenship behavior (OCB), little knowledge has been accumulated with respect to underlying mechanisms and boundary conditions affecting team creative performance and change OCB. To fill this research gap, this study aims at proposing and testing a moderated mediation model that delineates the relationships among positive group affective tone (PGAT), team reflexivity, team leader transformational leadership, team creative performance, and team change OCB. As hypothesized, PGAT was positively associated with team reflexivity, which in turn significantly predicted team creative performance and change OCB. In addition, the relationship between PGAT and team reflexivity and the indirect effects of PGAT on team creative performance and change OCB through team reflexivity were more pronounced when team leader transformational leadership was high than when it was low. These findings were validated in a post hoc analysis that compared the proposed moderated mediation model with alternative models.     

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。

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.     

团队领导行为与团队心理安全：以信任为中介变量的研究

The Moderating Roles of Perceived Task Interdependence and Team Size in Transformational Leadership’s Relation to Team Identification: A Dimensional Analysis

This study is aimed at investigating perceived task interdependence and team size as contingencies for team leaders’ transformational leadership influence on team identification. Data were obtained from a two-phase survey among 234 employees from ten multinational pharmaceutical subsidiaries in South Korea. Each dimension of transformational leadership by team leaders relates positively to team identification. However, the impact of leadership dimensions on team identification is attenuated by distinct moderator(s): charisma by higher perceived task interdependence, individualized consideration by larger team size, and intellectual stimulation by higher perceived task interdependence or larger team size. This study’s findings help us develop a more nuanced understanding of how transformational leadership operates. This study illustrates that team leaders’ transformational influence on team identification fluctuates, depending on the team structure. Such knowledge may help inform team leader development and team-structuring strategies used by practitioners and may contribute to improving organizational team effectiveness. This is one of the first studies showing evidence that the influence of the dimensions of transformational leadership is contingent upon distinct moderators, thereby contributing to advancing the theory of transformational leadership. Further, this study, by investigating team structure as a contingency of the transformational leadership-team identification relationship, complements previous research that focused on follower characteristics. Additionally, our explicit attention to the team as both the context of leaders’ action and the target of employee identification helps us gain a more concrete understanding of team leadership and team development issues, which are particularly salient in the highly competitive pharmaceutical industry.     

Openness to Experience and Team Creativity: Effects of Knowledge Sharing and Transformational Leadership

This study extends the research on the creative work process in teams by integrating personality traits, knowledge-sharing behavior, and transformational leadership. Analyses of multisource data from 347 members of 53 creative teams in 26 firms reveal the associations between heterogeneity of openness to experience in teams and team creativity (i.e., idea generation and idea development). Further, knowledge sharing mediated the relationships between personality heterogeneity and team creativity. Transformational leadership amplified the relationship between personality heterogeneity and idea development. Theoretical and practical implications are discussed.

在高不确定,高度竞争,高度挑战的任务情景下,领导力在团队中将扮演怎样的角色？变革型领导力与交易型领导力又是如何预测团队任务绩效的？为了回答这些问题,该研究对130名学生被试,31个团队,用ERP沙盘模拟游戏来进行模拟实验。通过高度模拟现实中企业经营的情景,从而提高实验结果的外部效度。实验结果表明,变革型领导力与交易型领导力都能够积极地预测团队任务绩效,消极领导力与任务绩效呈负相关,虽然并没有达到统计学显著水平,但研究结果的方向都支持了实验假设。     

How Do Happy Leaders Enhance Team Success? The Mediating Roles of Transformational Leadership,Group Affective Tone,and Team Processes1

Extending previous research regarding the relationship between leader positive moods and team performance, the present study examined 2 mediating mechanisms that explain the leader positive moods–team performance linkage: transformational leadership, and positive group affective tone. Data were collected from 85 sales teams (85 team leaders, 365 team members). Structural equation modeling analyses were performed to test the hypotheses. The results showed that leader positive moods not only directly enhanced team performance, but also indirectly led to improved team performance through the explicit mediating process (i.e., transformational leadership) and the implicit mediating process (i.e., positive group affective tone). Theoretical and practical implications are discussed.     

Age differences between leader and followers as a moderator of the relationship between transformational leadership and team performance

In a field study of 49 R&D teams in the pharmaceutical industry, the age difference between the team leader and the team members was examined as a moderator of the relationship between transformational leadership and team supervisors' longitudinal ratings of team performance. Data collected from 285 team members and 21 team supervisors showed that this relationship was positive when the leader was older than the other team members, but non‐significant when the leader's age was closer to the mean age of the team members. This finding broadens the still fragmentary knowledge of the conditions under which transformational leadership is likely to have more or less positive effects on team performance.     

Transformational leadership: relations to the five-factor model and team performance in typical and maximum contexts

This study examined the 5-factor model of personality, transformational leadership, and team performance under conditions similar to typical and maximum performance contexts. Data were collected from 39 combat teams from an Asian military sample (N = 276). Results found that neuroticism and agreeableness were negatively related to transformational leadership ratings. Team performance ratings correlated at only.18 across the typical and maximum contexts. Furthermore, transformational leadership related more strongly to team performance in the maximum rather than the typical context. Finally, transformational leadership fully mediated the relationship between leader personality and team performance in the maximum context but only partially mediated the relationship between leader personality and team performance in the typical context. The Discussion section focuses on how these findings, although interesting, need to be replicated with different designs, contexts, and measures.     

Person-supervisor fit,needs-supplies fit,and team fit as mediators of the relationship between dual-focused transformational leadership and well-being in scientific teams

Team-based work structures have become prevalent in science. Scientific teams, however, are characterized by competing individual-level and team-level needs (i.e., by mixed-motive situations). This makes leading scientific teams particularly challenging: Balancing competing individual-level goals and common team-level goals requires a specific type of leadership that simultaneously considers both satisfying individual-level needs as well as team-level needs. The current study addresses this issue by combining the dual-focused model of transformational leadership with person-environment fit theory. Specifically, we investigated needs-supplies fit, person-supervisor fit, and team fit as mediators of the relationship between transformational leadership and scientific team members’ job satisfaction and work-related strain. In doing so, we provide a new perspective on leadership in scientific teams by explicitly differentiating individual-level and team-level effects of transformational leadership. We tested our hypotheses using a three-wave design with a sample of 134 members of 42 scientific teams. The relationships between individual-focused transformational leadership, job satisfaction, and work-related strain were mediated by needs-supplies fit and person-supervisor fit. Team-focused transformational leadership was positively related to job satisfaction and negatively related to work-related strain. Our findings contribute to further clarifying the mechanisms underlying the relationship between transformational leadership and members’ well-being in scientific teams.     

Leading Military Teams to Think and Feel: Exploring the Relations Between Leadership,Soldiers' Cognitive and Affective Processes,and Team Effectiveness

The purpose of this study was to examine the relationships between leadership and military teams' affective and cognitive processes and the subsequent links between these processes and team effectiveness. Soldiers (N = 148) from 32 teams completed questionnaires assessing these variables. Hierarchical linear modeling was used to analyze the data. Transformational leadership was positively associated with cognitive and affective processes, but only active management-by-exception leadership was related to negative affect. Neither form of management-by-exception leadership related to cognitive processes. Positive affect, negative affect, and cognitive processes were all related to team viability. Finally, some mediation effects were observed. Implications of the results for developing leadership in military teams are drawn.     

Principals' transformational leadership and teachers' collective efficacy

The study was designed to test the relationship of principals' transformational, transactional, and laissez-faire leadership with teachers' collective efficacy. Bandura's theory of efficacy applied to the group and Bass's transformational leadership theory were used as the theoretical framework. Participants included 487 French Canadian teachers from 40 public high schools. As expected, there were positive and significant correlations between principals' transformational and transactional leadership and teachers' collective efficacy. Also, there was a negative and significant correlation between laissez-faire leadership and teachers' collective efficacy. Moreover, regression analysis showed transformational leadership significantly enhanced the predictive capabilities of transactional leadership on teachers' collective efficacy. These results confirm the importance of leadership to predict collective efficacy and, by doing so, strengthen Bass's theory of leadership.     

Leader Network Centrality and Team Performance: Team Size as Moderator and Collaboration as Mediator

The social network perspective provides a valuable lens to understand the effectiveness of team leaders. In understanding leadership impact in team networks, an important question concerns the structural influence of leader centrality in advice-giving networks on team performance. Taking the inconsistent evidence for the positive relationship of network centrality and leadership effectiveness as a starting point, we suggest that the positive impact of leader centrality in advice-giving networks is contingent on team needs for leadership to meet communication and coordination challenges, which we argue are larger in larger teams. Developing our analysis, we examine the mediating role of member collaboration in the relationship of leader network centrality and team performance as moderated by team size. Based on a multi-source dataset of 542 employees and 71 team leaders, we found that leader centrality in advice-giving networks related positively to team performance in larger teams but negatively in smaller teams. Results supported the mediated moderation model via member collaboration in smaller teams, but not in larger teams.

     

Transformational leadership and task cohesion in sport: The mediating role of intrateam communication

ObjectivesLittle is known about the mechanisms that might mediate the relationship between transformational leadership behaviors and follower outcomes in the sporting domain. The purpose of this study was to examine whether intrateam communication mediated the effects of transformational leadership behaviors on task cohesion.Design/MethodsA cross-sectional study of university level ultimate frisbee players (N = 199). Participants completed a measure assessing their perceptions of their captain's transformational leadership behaviors. Post-competition, participants completed measures assessing perceptions of intrateam communication and task cohesion within their own team.ResultsMultilevel analyses revealed intrateam communication to partially mediate the relationships between two of the transformational leadership behaviors and task cohesion.ConclusionsIntrateam communication is seen to be a mechanism that explains the relationship between transformational leadership and task cohesion. Overall, the results support and add to the range of positive effects associated with transformational leadership in sport, and are suggestive of interventions that may raise levels of team cohesion.
