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.     

LMX in team-based contexts: TMX,authority differentiation,and skill differentiation as boundary conditions for leader reciprocation

The purpose of the current study is to develop an integrated theoretical model based upon social exchange theory focused on the simultaneous interplay of leader–member exchange (LMX) and team–member exchange (TMX) in team-based contexts. We propose a model that extends current theories related to social exchange by integrating currently independent propositions in the literatures on LMX and TMX, showing how these propositions are contingent on the nature of the team in which leaders and followers are embedded. In a sample of 439 employees on 61 teams, the results show that when it comes to predicting individual performance (a) high TMX quality eliminates the otherwise negative effects of low LMX quality, (b) low authority differentiation weakens the otherwise positive effects of LMX, and (c) high skill differentiation weakens the otherwise positive effects of high LMX quality on performance. We discuss how the role of LMX may be changing in contemporary team-based work contexts relative to what was true in the historical literature when the construct was originally developed.     

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.     

Centrality and charisma: comparing how leader networks and attributions affect team performance

When leaders interact in teams with their subordinates, they build social capital that can have positive effects on team performance. Does this social capital affect team performance because subordinates come to see the leader as charismatic? We answered this question by examining 2 models. First, we tested the charisma-to-centrality model according to which the leader's charisma facilitates the occupation of a central position in the informal advice network. From this central position, the leader positively influences team performance. Second, we examined the centrality-to-charisma model according to which charisma is attributed to those leaders who are socially active in terms of giving and receiving advice. Attributed charisma facilitates increased team performance. We tested these 2 models in 2 different studies. In the first study, based on time-separated, multisource data emanating from members of 56 work teams, we found support for the centrality-to-charisma model. Formal leaders who were central within team advice networks were seen as charismatic by subordinates, and this charisma was associated with high team performance. To clarify how leader network centrality affected the emergence of charismatic leadership, we designed Study 2 in which, for 79 student teams, we measured leader networking activity and leader charisma at 2 different points in time and related these variables to team performance measured at a third point in time. On the basis of this temporally separated data set, we again found support for the centrality-to-charisma model.     

Relative Leader–Member Exchange Within Team Contexts: How and when Social Comparison Impacts Individual Effectiveness

A multilevel model was developed to examine how and when a focal individual's leader–member exchange (LMX) relative to the LMXs of coworkers within the team (relative LMX, or RLMX) influences individual in‐role performance, organizational citizenship behavior (OCB), and job satisfaction. Results, based on a sample of 275 leader–member dyads within 35 teams of a beverage company, largely supported the hypotheses. Specifically, using multilevel polynomial regression analyses, the results showed that self‐efficacy partially mediated the relationship between RLMX and in‐role performance and job satisfaction, and fully mediated the relationship between RLMX and OCB. Furthermore, the results demonstrated that team identification attenuated RLMX's direct effect on self‐efficacy, and indirect effects on in‐role performance and OCB and team supportive behavior attenuated RLMX's direct effect on self‐efficacy and indirect effect on in‐role performance.     

LEADERSHIP EMERGENCE IN AUTONOMOUS WORK TEAMS: ANTECEDENTS AND OUTCOMES

The aim of this study was to investigate (a) personality attributes and cognitive ability ( g ) as determinants of leadership emergence in teams, and (b) the impact of leadership that can emerge from the team leader (operationalized as the team member with the highest leadership score) and other team members (staff) on team performance. Autonomous work team members who had been working together for 13 weeks were studied. Participants were 480 undergraduates in 94 initially leaderless teams of 5 or 6. We found that leadership emergence was associated most strongly with g , followed by conscientiousness, extraversion, and emotional stability. Teams performed best when both the team leader and staff were high in leadership. Furthermore, an effective team leader does not ameliorate the negative affects of a staff low in leadership.     

Meeting the need or falling in line? The effect of laissez-faire formal leaders on informal leadership

We consider the utility of two contrasting theoretical perspectives in explaining how laissez-faire formal leaders and team member motivation to lead (MTL) influences informal leadership and team task performance. The first perspective, functional leadership theory, is the dominant lens used currently to understand informal leadership. However, we suggest that social learning theory offers a compelling alternative account. In a multiwave survey study of 344 members of 72 work teams, we find support for the social learning theory predictions that laissez-faire formal leaders are perceived by team members to engage in less modeling of effective leadership and as a result are negatively associated with informal leadership and team task performance. We do not find support for the functional leadership theory predictions that laissez-faire formal leaders are positively associated with team members’ informal leadership and team task performance, which would be due to an increased perceived need for leadership. The social learning effects are stronger for teams that are lower in member MTL and weaker for teams that are higher in member MTL. These results suggest social learning theory may be preferable to functional leadership theory for understanding informal leadership in teams.     

THE EVOLVING MANAGER STEREOTYPE: THE EFFECTS OF INDUSTRY GENDER TYPING ON PERFORMANCE EXPECTATIONS FOR LEADERS AND THEIR TEAMS

This study examined how external evaluators' assessments of a management team and its leader are impacted by congruence between the leader's gender and the gender typing of the industry in which the team works. We experimentally tested our theory using industries that are either male typed or gender neutral, with teams led by male and female leaders. Results indicate that performance expectations for the team were more favorable when the leader's gender was congruent with the industry's gender typing, but expectations for the leader were not affected by gender congruence. These findings paradoxically suggest that evaluators form performance expectations for teams based upon individual characteristics of their leaders, even when these characteristics have no effect on the conscious assessments of the leaders themselves.     

When and How Does LMX Differentiation Influence Followers’ Work Outcomes? The Interactive Roles of One's own LMX Status and Organizational Context

The fundamental premise of the leader–member exchange (LMX) theory is that leaders’ relationships with their followers vary in quality. Although LMX differentiation (i.e., within‐group variation in the quality of LMX) is generally considered a sound leadership practice, its effects on group members’ work outcomes remain poorly understood. Drawing on LMX and upper echelons theories, this study suggests that employees’ reactions to LMX differentiation depend on the personal LMX status of employees and the characteristics of the organizational context. Analyses of multilevel data collected from 502 employees organized into 135 work groups in 34 firms show that the impact of LMX differentiation on work outcomes is more positive (or less negative) for employees with lower rather than higher LMX. The findings highlight the importance of organizational boundary conditions for these interactions: The negative moderation by one's own LMX status is stronger when top managers decentralize responsibilities to lower hierarchical levels and weaker when top managers impose a shared vision to guide the organization.     

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.     

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.

     

员工为什么乐于助人?多层次的领导–部属交换对帮助行为的影响

基于社会交换理论,以56名直属主管和274名下属的配对数据为样本,考察了多层次的领导–部属交换对个体和团队层次上的帮助行为的影响及作用过程。跨层次分析结果表明:(1)个体层次的人际公平中介了个体和团队层次的领导–部属交换对员工帮助行为的影响;(2)团队层次的人际公平氛围中介了团队平均领导–部属交换对个体和团队层次的帮助行为的影响;(3)领导–部属交换关系差异化对个体和团队层次的领导–部属交换与帮助行为之间的正向关系均具有显著的负向调节作用,即相对于较高的领导–部属交换关系差异化,较低的领导–部属交换关系差异化强化了个体和团队层次的领导–部属交换对帮助行为的影响。     

The role of decision influence and team performance in member self-efficacy, withdrawal, satisfaction with the leader, and willingness to return

This study examines team performance as a moderator of the relationship between decision influence and outcomes relevant to team effectiveness in hierarchical teams with distributed ex pertise. In this type of team staff members have unique roles and make recommendations to the team leader, who ultimately makes the team's final decisions. It is suggested that the positive rela tionship between decision influence and favorable outcomes (e.g., satisfaction) consistently described in the literature is dependent on team performance in this type of team. Specifically, team effec tiveness outcomes are proposed to be consistently more favorable in higher performing than in lower performing teams. Decision influence is proposed to relate positively to member satisfaction with the leader, willingness to return, and self-efficacy and to relate negatively to withdrawal in higher performing teams. The opposite pattern of relationships is expected in lower performing teams. A laboratory study was conducted with 228 undergradu ates performing a computer task as subordinates in 76 four-person teams with a confederate leader. The results generally support the hypotheses and illustrate a dilemma for leaders attempting to manage team effectiveness.     

领导–下属心理资本一致性对周边绩效的影响——工作关系与私人关系的中介作用

本文基于相似吸引理论,考察了领导–下属心理资本一致性能否影响双方的工作关系(领导–下属交换,LMX)和私人关系(领导–下属关系,SSG),继而塑造下属的周边绩效。采用多项式回归和响应面分析技术,对164份领导–下属配对数据进行分析,结果表明：领导–下属心理资本越一致,双方的LMX和SSG越高;在一致情形下,与“低–低一致”相比,”高–高一致”时的LMX和SSG更高。领导–下属心理资本一致性通过LMX、SSG影响下属的周边绩效。以上结果能为如何有效利用心理资本管理领导–下属的人际互动、下属周边绩效提供启发。     

The impact of identity leadership on team functioning and well-being in team sport: Is psychological safety the missing link?

The purpose of this study was to investigate the role of psychological safety in explaining the impact of identity leadership on team performance and athlete well-being. Adopting a cross-sectional survey design, 289 handball players rated the identity leadership skills of their coach, their captain, and the informal leaders in the team, as well as various performance- and well-being-related measures. Structural equation modelling (controlling for the nested structure of our data) revealed that by demonstrating identity leadership, coaches, captains, and in particular informal athlete leaders, all had a unique contribution in strengthening their team members’ identification with their team. By this shared sense of ‘us’, athletes felt psychologically safe in their team to speak up, provide input, and take risks. In line with our hypotheses, this sense of psychological safety acted as a mediator between identity leadership and two subsequent pathways: (1) a team-oriented pathway in which psychological safety inspired good teamwork, which fostered team resilience and, in turn, enhanced athletes’ satisfaction with their team’s performance; and (2) an individual-oriented pathway wherein psychological safety buffered against athletes’ burnout, thereby enhancing their health. In addition to these pathways mediated by psychological safety, the informal leaders directly influenced the performance pathway (with total effect sizes being 10 times larger than those of coaches and team captains), whereas coaches had a direct influence on the health pathway (with total effect sizes being three times larger than those of informal leaders and captains). Given the often-underestimated importance of the informal leaders, sport teams can be recommended to adopt a structure of shared leadership in which team members are encouraged to engage in identity leadership. In conclusion, we found that by nurturing a shared sense of ‘we’ and ‘us’ within the team, leaders are able to foster a psychologically safe environment, which in turn paves the way for an optimal team functioning and a healthier team.     

Supervisors' upward exchange relationships and subordinate outcomes: testing the multilevel mediation role of empowerment

This study empirically examined the proposition that supervisors' exchange relationships with their own supervisors (i.e., leader-leader exchange, or LLX) are related to their subordinates' work-related outcomes through 3 mechanisms: (a) leaders modeling their LLX to develop and maintain their exchange relationships with their subordinates (i.e., leader-member exchange, or LMX), (b) motivating the team and its members, captured by team and individual empowerment, and (c) facilitating the relationships between LMX and individual outcomes. Analyses of multisource and lagged data from 104 team supervisors and 577 subordinates showed that LMX mediated the positive relationship of LLX on subordinates' individual empowerment. Furthermore, team empowerment and individual empowerment sequentially mediated the positive relationships between LLX and subordinates' job satisfaction and job performance. The authors also found that the indirect relationships of LMX with job satisfaction and job performance via individual empowerment were stronger when LLX was higher. Theoretical and practical implications of these findings are discussed.     

Informal Hierarchy and Team Creativity: The Moderating Role of Empowering Leadership

Although there is growing evidence that strong informal influence hierarchies can enhance teams' core task performance, recent theorising suggests that such informal hierarchies may, at the same time, stifle team creativity. The current study draws from the Motivated Information Processing in Groups (MIP-G) model to empirically examine this latter notion. Moreover, we build on functional leadership theories to propose that the link between informal hierarchy strength and team creativity hinges on a formal team leader's empowering leadership. Using a sample of 56 organisational work teams comprising 304 individuals from a wide range of industries, we found that stronger informal influence hierarchies related negatively with team creativity when the formal leader exhibited little empowering behaviour. When the formal leader acted in more empowering ways, by contrast, this negative relationship was dampened. These findings provide new knowledge on the role of informal influence hierarchies for team creativity and advance our understanding of how informal hierarchical relations and formal leadership processes can jointly shape important team outcomes.     

Investigating a process model for leader affective presence,interpersonal emotion regulation,and interpersonal behaviour in teams

Leader affective presence is the tendency of leaders to elicit feelings that are consistent among other individuals, and has been supported as a relevant personality trait for understanding teamwork. Drawing on a model that integrates personality and emotion regulation, this study aimed to expand research on affective presence by proposing team members’ perceptions of leader interpersonal emotion regulation as a process that explains how leader affective presence is related to team member behaviour. In the model, teamness—the perception that interdependence and reflexivity are required in the team—is presented as a boundary condition to the effects of affective presence via emotion regulation. Results of a study conducted with 99 teams showed that team member ratings of leader positive affective presence were linked to their perceptions that leaders had used affect-improving emotion regulation which in turn was associated with greater team citizenship behaviour. Contrariwise, team member ratings of leader negative affective presence were associated with perceived use of affect-worsening emotion regulation by leaders which in turn was associated with lower levels of team citizenship, but only when teams were low in teamness. These findings contribute to understanding how leaders’ individual differences are related to teamwork through affective processes.     

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.     

Are Pre-Assembly Shared Work Experiences Useful for Temporary-Team Assembly Decisions? A Study of Olympic Ice Hockey Team Composition

The purpose of this study was to investigate if pre-assembly shared work experiences among temporary team members facilitate individual and team performance. Archival data from the 2014 Men’s Olympic Ice Hockey Tournament (12 teams, 25 players each) was used in the study. Measures of social network centrality were computed based on the pre-assembly shared work experiences among national team members derived from professional and amateur affiliations. These measures were used to predict objective individual and team performance criteria. Players’ closeness centrality scores, from pre-assembly shared work experience networks, positively predicted their goals, assists, and being involved in more positive than negative plays. Teams with less centralized pre-assembly shared work experience network structures tended to perform better than teams with more centralized pre-assembly shared work experience network structures. Temporary teams are commonly used by organizations to perform tasks that are specific, important, and of short duration. Because temporary teams have little time to develop the shared properties required for effective team functioning, assembly decisions are of paramount importance. The results from this study suggest that centrality measures derived from pre-assembly shared work experiences are useful to consider when assembling temporary teams. Few studies have investigated the impact of pre-assembly shared work experiences on individual and team performance. Using objective data, this study provides evidence that pre-assembly shared work experiences relate to individual and team performance in temporary teams, supporting the need for expanded research in this area.
