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.     

EFFECTS OF ROTATED LEADERSHIP AND PEER EVALUATION ON THE FUNCTIONING AND EFFECTIVENESS OF SELF-MANAGED TEAMS: A QUASI-EXPERIMENT

In a quasi-experiment of 38 self-managed undergraduate teams, we examined the effects of team designs that differed with respect to the form of member evaluation and team leadership. Relative to teams that relied on external evaluations, teams with peer evaluations had higher levels of workload sharing, voice, cooperation, performance, and member satisfaction. Relative to teams that relied on leader emergence, teams that rotated leadership among members had higher levels of voice, cooperation, and performance. Overall, results of the study demonstrate the potential importance of team-design decisions in self-managed teams.     

The external leadership of self-managing teams: intervening in the context of novel and disruptive events

Relatively little empirical research has been conducted on external leaders of self-managing teams. The integration of functional leadership theory with research on team routines suggests that leaders can intervene in teams in several different ways, and the effectiveness of this intervention depends on the nature of the events the team encounters. External team leaders from 3 organizations first described a series of events (N=117), and leaders and team members then completed surveys to quantitatively describe the events. Results indicated that leader preparation and supportive coaching were positively related to team perceptions of leader effectiveness, with preparation becoming more strongly related to effectiveness as event novelty increased. More active leader intervention activities (active coaching and sense making) were negatively related to satisfaction with leadership yet were positively related to effectiveness as events became more disruptive.     

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.     

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.     

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.     

Attachment style and individual differences in leadership perceptions and emergence

The authors examined whether individuals' approaches to relationships, expressed in terms of attachment styles, was related to how they viewed ideal leadership and to their degree of tendency to emerge as team leaders. Specifically, the authors hypothesized that attachment styles, or cognitive representations of orientation to others, would explain individual differences in leadership perceptions and emergence. Participants were 127 American students in college teams. The authors found that securely attached individuals (n = 81) perceived themselves as more effective team members than did insecurely attached individuals (n = 46) and that fellow team members saw securely attached team members as emerging team leaders significantly more often than they did insecurely attached team members.     

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.     

The role of justice in team member satisfaction with the leader and attachment to the team

This study examined the effects of team decision accuracy, team member decision influence, leader consideration behaviors, and justice perceptions on staff members' satisfaction with the leader and attachment to the team in hierarchical decision-making teams. The authors proposed that staff members' justice perceptions would mediate the relationship between (a) team decision accuracy, (b) the amount of influence a staff member has in the team leader's decision, and (c) the leader's consideration behaviors and staff attachment to the team and satisfaction with the leader. The results of an experiment involving 128 participants in a total of 64 teams, who made recommendations to a confederate acting as the team leader, generally support the proposed model.     

The Relative Contribution of Emotional Competence and Cognitive Ability to Individual and Team Performance

The relative contributions of emotional competence and cognitive ability to individual and team performance, team-member attitudes, and leadership perceptions were examined. Focusing on emotional competencies, we predicted that, although both cognitive ability and emotional competence would predict performance, cognitive ability would account for more variance on individual tasks, whereas emotional competence would account for more variance in team performance and attitudes. We also predicted that emotional competence would be positively related to team attitudes and to both leader emergence and effectiveness. Using a sample of undergraduate business majors who completed tasks alone and as members of teams, our results generally supported the hypotheses. Implications for the reach and impact of work relating emotional competencies to performance are offered.     

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.     

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.     

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.

     

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.     

Contingent leadership and effectiveness of trauma resuscitation teams

This research investigated leadership and effectiveness of teams operating in a high-velocity environment, specifically trauma resuscitation teams. On the basis of the literature and their own ethnographic work, the authors proposed and tested a contingency model in which the influence of leadership on team effectiveness during trauma resuscitation differs according to the situation. Results indicated that empowering leadership was more effective when trauma severity was low and when team experience was high. Directive leadership was more effective when trauma severity was high or when the team was inexperienced. Findings also suggested that an empowering leader provided more learning opportunities than did a directive leader. The major contribution of this article is the linkage of leadership to team effectiveness, as moderated by relatively specific situational contingencies.     

Cognition-based and affect-based trust as mediators of leader behavior influences on team performance

We develop a model in which cognitive and affective trust in the leader mediate the relationship between leader behavior and team psychological states that, in turn, drive team performance. The model is tested on a sample of 191 financial services teams in Hong Kong and the U.S. Servant leadership influenced team performance through affect-based trust and team psychological safety. Transformational leadership influenced team performance indirectly through cognition-based trust. Cognition-based trust directly influenced team potency and indirectly (through affect-based trust) influenced team psychological safety. The effects of leader behavior on team performance were fully mediated through the trust in leader variables and the team psychological states. Servant leadership explained an additional 10% of the variance in team performance beyond the effect of transformational leadership. We discuss implications of these results for research on the relationship between leader behavior and team performance, and for efforts to enhance leader development by combining knowledge from different leadership theories.     

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 Role of Leadership and Trust in Creating Structural Patterns of Team Procedural Justice: A Social Network Investigation

We adopt a social network perspective to investigate the distinct structural patterns (i.e., centralization and density) of procedural justice (PJ) in teams and the antecedent factors that create them. Across 2 longitudinal field studies in which we gathered social network data from 1,008 workers on 138 teams (Study 1) in China and 672 workers on 125 teams (Study 2) in the United States, we found that differentiation in leader–member exchange relationships significantly influenced the centralization and density of PJ within a team by affecting the level of intrateam trust. Specifically, the more differentiated leader treatment team members received, the lower the level of trust within a team, which resulted in more concentrated (high centralization) and fewer (low density) social interactions among members regarding team PJ. Furthermore, differentiated leader treatment of team members was especially damaging to intrateam trust and, in turn, the structural patterns of team PJ when team members were in close proximity and highly sensitive to equity issues.     

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.     

Antecedents of daily team job crafting

This study investigated potential antecedents of team job crafting defined as the extent to which team members engage together in increasing (social and structural) job resources and challenges, and decreasing hindering job demands. Mindful of the teamwork literature, we hypothesized that individual employee factors (self-efficacy for teamwork, daily affect), team features (team cohesion, climate) and the organizational context of teams (engaging leadership and organizational resources for teamwork) relate positively to daily team job crafting behaviour. Data were collected among 46 multi-professional rehabilitation teams whose members completed two daily surveys after their weekly meetings. Multilevel regression analyses showed that self-efficacy for teamwork and team members’ positive affect were positively associated with team job crafting behaviour at the individual (within-team) level. In addition, a team climate characterized by a clear vision of the teams’ targets, supportiveness and innovation and connecting leadership were positively related to daily team job crafting at both the within- and between-team levels of the data. Overall, the study offers novel insights into the antecedents of teams’ daily job crafting behaviours. For practice, the results suggest that actions and interventions conducive to positive team processes offer the most promising route to enhancing team job crafting behaviour.
