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.     

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.     

A LONGITUDINAL EXAMINATION OF CONCOMITANT CHANGES IN TEAM LEADERSHIP AND CUSTOMER SATISFACTION

For each of three 1‐year time periods, we examined the relationship between changes in the team leadership of branch managers (as measured by employee ratings) and concomitant changes in customer satisfaction for branches of a regional bank. Specifically, for the time period 2001–2002, we examined concomitant changes in team leadership and customer service satisfaction with 68 branch managers; between 2002–2003 and 2003–2004 we examined these relationships for 46 and 40 of the remaining 68 branch managers, respectively. We expected that improvements (declines) in team leadership ratings would be accompanied by concomitant changes (i.e., improvement or decline) in customer satisfaction ratings. We found that, in 2 of the 3 time periods we examined, improvements (declines) in team leadership were related to improvements (declines) in customer satisfaction. We interpret these findings using the service climate literature.     

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.     

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.

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.     

SELECTING INDIVIDUALS IN TEAM SETTINGS: THE IMPORTANCE OF SOCIAL SKILLS, PERSONALITY CHARACTERISTICS, AND TEAMWORK KNOWLEDGE

Although work is commonly organized around teams, there is relatively little empirical research on how to select individuals in team-based settings. The goal of this investigation was to examine whether 3 of the most commonly used selection techniques for hiring into traditional settings (a structured interview, a personality test, and a situational judgment test) would be effective for hiring into team settings. In a manufacturing organization with highly interdependent teams, we examined the relationships between social skills, several personality characteristics (Conscientiousness, Extraversion, Agreeableness, and Emotional Stability), teamwork knowledge, and contextual performance. Results indicate that each of these constructs is bivariately related to contextual performance in a team setting, with social skills, Conscientiousness, Extraversion, and teamwork knowledge incrementally predicting contextual performance (with a multiple correlation of .48). Implications of these results for selection in team and traditional settings are discussed.     

KNOWLEDGE WORKER TEAM EFFECTIVENESS: THE ROLE OF AUTONOMY, INTERDEPENDENCE, TEAM DEVELOPMENT, AND CONTEXTUAL SUPPORT VARIABLES

This study investigated how autonomy, interdependence, and team development, along with process and contextual support variables, were related to the effectiveness of teams of "knowledge workers." The sample included 231 knowledge workers from 27 work teams. Team members completed surveys measuring the design, process, and contextual factors. Effectiveness measures included multiple key stakeholder evaluations of team performance and self-report measures of attitudinal outcomes. The results suggest that interactions among design, process, and contextual support factors have important implications for team effectiveness. In particular, the positive relationship between team autonomy and team job motivation was reduced as teams worked under more interdependent conditions. This interaction effect also varied across the types of autonomy (e.g., planning-related, product-related, and people-related) the team was given. Results also demonstrated that the relationship between job motivation and team process behaviors (helping, sharing, and innovating) was more positive in teams who were developmental mature. Process behaviors were positively related to effectiveness, but those relationships became more positive in the presence of certain contextual factors (high-quality goals and efficient information transmission), and less positive in the presence of others (feedback and time pressure). Future research needs and practical implications of these results are discussed.     

Inside the leader relationship: constructive controversy for team effectiveness in China

Research is needed to understand the dynamics by which high‐quality leader relationships have their productive effects on followers. This study proposes that these leader relationships do not simply induce compliance but encourage employees and managers to discuss their diverse views open‐mindedly and constructively. Team leaders indicated leader–member relationship with employees who rated their constructive controversy and their team's effectiveness and feelings of respect, support, and reduced stress. Structural equation analysis suggested that leader–member relationship affects employee team productivity and emotions through constructive controversy. The study's findings and previous research were interpreted as suggesting that high‐quality leader relationships coupled with constructive controversy provide a foundation for effective team leadership in China.     

Personality and the Perception of Transformational Leadership: The Impact of Extraversion,Neuroticism, Personal Need for Structure,and Occupational Self‐Efficacy1

This experimental study examined the influence of followers' personal characteristics on their perception of leadership. Participants were 175 students who self‐rated several personality scales (extraversion, neuroticism, personal need for structure, and occupational self‐efficacy) at Time 1. Two weeks later, participants were divided into two groups and were presented a vignette about a transformational or a nontransformational leader. Subsequently, respondents were asked to rate the described leader's behavior on the Multifactor Leadership Questionnaire. Results revealed that followers high in extraversion tended to perceive more transformational leadership, and showed a more positive evaluation of transformational leadership than did followers with low extraversion. Moreover, perceived transformational leadership predicted the acceptance of a leader, but followers' personality traits did not moderate the relationship between perceived transformational leadership and acceptance.     

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.     

A META-ANALYSIS OF TEAMWORK PROCESSES: TESTS OF A MULTIDIMENSIONAL MODEL AND RELATIONSHIPS WITH TEAM EFFECTIVENESS CRITERIA

Drawing from Marks, Mathieu, and Zaccaro (2001) , we proposed that narrowly focused teamwork processes load onto 3 higher-order teamwork process dimensions, which in turn load onto a general teamwork process factor. Results of model testing using meta-analyses of relationships among narrow teamwork processes provided support for the structure of this multidimensional theory of teamwork process. Meta-analytic results also indicated that teamwork processes have positive relationships with team performance and member satisfaction, and that the relationships are similar across the teamwork dimensions and levels of process specificity. Supplemental analyses revealed that the 3 intermediate-level teamwork processes are positively and strongly related to cohesion and potency. Results of moderator analyses suggested that relationships among teamwork processes and team performance are somewhat dependent on task interdependence and team size.     

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.     

Observed Leadership Potential of Personnel in a Team Setting: Big Five traits and proximal factors as predictors

The authors explored implications of Big Five traits and proximal factors for the observed leadership potential of personnel in newly formed teams. Big Five traits were designated as distal factors having indirect links to observed leadership potential via three proximal factors: individual perception of team cohesion, team‐oriented proactivity, and teamwork knowledge. Drawing from implicit personality theory, the authors introduced a team‐leader personality profile as a higher‐order construct for explaining covariation among extraversion, conscientiousness, and emotional stability. A structural analysis of data from 472 personnel supported hypothesized relationships. Specific findings included validation of a team‐leader personality profile and preliminary support for the measure of team‐oriented proactivity that was developed for this study. Implications of the various findings are discussed.     

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.     

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.

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.     

A motivated information processing perspective on the antecedents of empowering leadership

Empowering leadership is an important influence on team effectiveness. This makes the question of what the antecedents of team empowering leadership are an important issue to consider. To address this question, we propose a motivated information processing perspective that holds that engaging in empowering leadership is based on social information processing, and that there are individual differences in how elaborate that information processing is. We argue that a key consideration in shifting control from the leader to the team is the extent to which empowering leadership is driven by leaders’ consideration of their trust in the team (i.e., an instance of social information processing), and that leader need for closure (a trait capturing the disposition to carefully consider decisions and actions) moderates the relationship between leader trust in team and empowering leadership. A survey of N = 156 work teams supported these hypotheses.
