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.     

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.     

差异化变革型领导对知识分享与团队创造力的影响:社会网络机制的解释

差异化变革型领导是团队领导领域的最新议题,现有的研究局限于探讨其社会心理方面的作用机制。本文从社会网络机制出发解释差异化变革型领导对团队知识分享及团队创造力的影响。基于65家企业的225个工作团队样本的结构方程模型分析表明,团队一致性变革型领导正向影响团队交流网络密度从而提高团队知识分享;个体差异性变革型领导正向影响团队成员交流网络密度差异性从而降低团队知识分享;团队知识分享正向影响团队创造力。本文的证据表明,在中国情境下,差异性团队领导行为不利于创造稠密的团队交流网络,以及团队知识分享,从而不利于提升团队创造力水平。     

An examination of when and how leader political skill influences team performance in China: A cultural value perspective

This study examined the relationship between leader political skill and team performance, as well as the mediating (team cohesion) and moderating (power distance) variables of the relationship. Our theoretical model was tested using data collected from employees in a food service company. Analyses of multisource and lagged data from 59 teams and 276 members indicated that leader political skill was positively related to team performance via team cohesion. Further, both the relationship between leader political skill and team cohesion and the indirect relationship between leader political skill and team performance were stronger when teams exhibited lower power distance.     

The shared leadership process in decision-making teams

The present study examined the process of shared leadership in 45 ad hoc decision-making teams. Each team member's leadership behavior (n = 180) was assessed by behaviorally coding videotapes of the teams' discussions. The within-team patterns of leadership behavior were examined using cluster analysis. Results indicated that the likelihood of a team experiencing a full range of leadership behavior increased to the extent that multiple team members shared leadership, and that teams with shared leadership experienced less conflict, greater consensus, and higher intragroup trust and cohesion than teams without shared leadership. This study supports previous findings that shared leadership contributes to overall team functioning, and begins to delineate the extent to which team members may naturally share leadership.     

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.     

Perceived shared understanding in teams: The motivational effect of being ‘on the same page’

This study examines the role of perceived shared understanding with regard to team performance, taking into account the motivational mechanisms (i.e., group potency and team effort) involved in this relationship and the moderating role of task routineness. Using a multisource approach and a team‐level design, we collected data from 101 teams (i.e., 381 members and their 101 immediate superiors) working in a Canadian public safety organization. The results support the mediating role of group potency and team effort in the relationship between perceived shared understanding and team performance. Moreover, the results show that the relationship between team effort and team performance is moderated by task routineness, such that this relationship is stronger when task routineness is high. On the whole, the findings of this study help to better understand why and under what circumstances perceived shared understanding may enhance team performance.     

Shared leadership and team effectiveness: The examination of LMX differentiation and servant leadership on the emergence and consequences of shared leadership

This study examined the effects of leader–member exchange (LMX) differentiation on team-shared leadership and team effectiveness. Drawing on the group engagement model, we suggested that LMX differentiation negatively affects team-shared leadership and team effectiveness (i.e., team performance and team organizational citizenship behavior [OCB]). Servant leadership weakens the negative effects of LMX differentiation on shared leadership. We tested our predictions using data from a sample of 336 salespersons nested in 110 sales teams in China. We found that shared leadership mediated the relationships between LMX differentiation with both team performance and team OCB. In addition, servant leadership moderated the relationship between LMX differentiation and shared leadership and the indirect relationship between LMX differentiation with both team performance and team OCB.     

Different roles of shared and vertical leadership in promoting team creativity: Cultivating and synthesizing team members’ individual creativity

Drawing on the componential model of creativity (Amabile), we examined how shared leadership and a formally appointed leader's transformational leadership jointly cultivate team creativity in two studies. We conducted an experiment with a sample of 109 undergraduate students (32 teams) enrolled in a business plan competition (Study 1) and a field survey based on multisource, time-lagged data collected from 251 full-time employees working on 64 research and development teams (Study 2). The results from both studies revealed that shared leadership enhanced team members’ individual creative self-efficacy and individual creativity, which in turn improved team creativity. Moreover, the results from Study 2 showed that a formally appointed leader's use of different transformational leadership behaviors had different impacts on individual and team creativity. Individual-focused transformational leadership strengthened the positive effect of shared leadership on team members’ average individual creativity, whereas group-focused transformational leadership facilitated the translation of teams with high average individual creativity into teams with high levels of team creativity. The theoretical and practical implications of the findings are discussed.     

The building blocks of shared leadership: The interactive effects of diversity types,team climate,and time

Despite the wealth of empirical studies and recent meta-analyses demonstrating the positive performance effects of shared leadership, knowledge regarding antecedents is limited. We draw upon a collective approach to leadership identity construction theory and team diversity in order to understand the member attributes that impact leadership sharing. We suggest that both informational/functional and social categorization diversity types are important dimensions when considering shared leadership antecedents. First, we suggest functional diversity will result in higher levels of shared leadership but will only be realized when teams elicit a cooperative climate. Second, we suggest that gender diversity, a salient social category, will have a negative impact on shared leadership, particularly in a low cooperative climate. We further hypothesize these effects will change over time as the positive effects of functional diversity strengthen and the negative effects of gender differences weaken. We test our hypotheses, including the impact on team performance, in a time-lagged sample of 267 undergraduate students in 73 teams competing in a complex business simulation and a constructive replication with 142 MBA students in 41 teams. Theoretical and practical implications are discussed.     

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.     

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.     

The effects of situational goal orientation and cultural learning values on team performance and adaptation to change

In this paper, we examine the unique effects of situational goal orientation and cultural learning values on team adaptation to change and the moderating role of cultural learning values in the relationship between goal orientation and team performance and adaptation. To do this, we conducted an experiment using a 2 × 2 × 2 repeated-measures factorial design, consisting of high and low levels of learning values, situational goal orientation (i.e., learning goals and performance goals). The experimental task involved two phases: we looked at team performance in Phase 1 and team adaptation to change in Phase 2. Forty 3-person teams were randomly assigned to four experimental conditions and all teams engaged in a complex bridge-planning task. Performance was measured in terms of the quality of the planned bridge. Results showed independent effects of situational goal orientation and cultural learning values on team performance and adaptation to change. Cultural learning values also moderated the relationship between goal orientation and performance and adaptation to change. Finally, the combination of learning goals and high learning values resulted in the highest levels of initial team performance (Phase 1) and adaptation to change and improved performance (Phase 2), as compared to all other examined conditions.     

Demographic faultlines: a meta-analysis of the literature

We propose and test a theoretical model focusing on antecedents and consequences of demographic faultlines. We also posit contingencies that affect overall team dynamics in the context of demographic faultlines, such as the study setting and performance measurement. Using meta-analysis structural equation modeling with a final data set consisting of 311 data points (i.e., k [predictor-criterion relationships]), from 39 studies that were obtained from 36 papers with a total sample size of 24,388 individuals in 4,366 teams, we found that sex and racial diversity increased demographic faultline strength more than did diversity on the attributes of functional background, educational background, age, and tenure. Demographic faultline strength was found to increase task and relationship conflict as well as decrease team cohesion. Furthermore, although demographic faultline strength decreased both team satisfaction and team performance, there was a stronger decrease in team performance than in team satisfaction. The strength of these relationships increased when the study was conducted in the lab rather than in the field. We describe the theoretical and practical implications of these findings for advancing the study of faultlines.

Substitutes for leadership in anaesthesia teams and their impact on leadership effectiveness

In this study we aim to increase our understanding of leadership in anaesthesia teams by investigating the relationship between substitutes for leadership, leadership behaviour, and team performance in situations with varying levels of routine and standardization. The present study relied on video recordings of 12 anaesthesia teams in a simulated setting with the occurrence of a nonroutine event. Clinical team performance was measured by the speed of adequate team reaction to this event. The leadership behaviours observed were coded either as content oriented (e.g., information transmission) or structuring (e.g., assigning tasks). Results showed that leadership behaviour changed depending upon the level of routine of a situation, the degree of standardization, and, to some extent, on the experience of team members. Leadership tends to be positively related to team performance during nonroutine and low standardized situations but negatively related to team performance in routine and highly standardized situations. Furthermore, leadership is only slightly related to team member experience. This study improves our understanding of influences of substitutes for leadership on successful leadership behaviour in anaesthesia teams. The findings also lead to suggestions for both further research and the enhancement of team leadership in critical care.     

CEO Ideational Facilitation Leadership and Team Creativity: The Mediating Role of Knowledge Sharing

The development of new ventures is often based on collective creative efforts. We conceptualize team creativity as a process of looking for and exploring new solutions and examine whether and how CEO leadership fosters creativity in top management teams (TMT). Data collected from senior executive teams indicate that CEO ideational facilitation leadership is positively related to team knowledge sharing, which in turn results in enhanced team exploratory behaviors. These findings bear important theoretical implications for ways in which leaders can enhance creativity in teams and augment the entrepreneurial direction of executive teams.

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.     

Establishing team knowledge coordination from a learning perspective

Research has identified the importance of knowledge coordination in high-performing teams. However, little is known on the processes through which these cognitive structures are developed, more specifically on the learning occurring as teams communicate and interact to build new team knowledge. In a multiple-measures experiment, 33 teams with no prior experience in flight simulations were assigned to newly formed dyads to complete 4 successive performance episodes of a flight simulation task, modeling a complex, fast-paced, and high workload task context. The study showed how team learning processes (i.e., team learning behaviors and team reflexivity), driven by task cohesion, and group potency supported coordination development, which in turn predicted team performance.
