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.     

Day-level transformational leadership and followers’ daily level of stress: a moderated mediation model of team cooperation,role conflict,and type of communication

This study contributes to the literature on leadership by linking day-level transformational leadership behaviour with employees’ daily level of stress. A first-stage moderated mediation framework consisting of team cooperation, role conflict, and type of daily communication is introduced to specify how and when leaders’ transformational behaviour is related to followers’ daily stress. Two hundred five participants took part in a diary study over five consecutive working days and provided information on their leaders’ transformational behaviour, team cooperation, role conflict, type of communication with supervisors, as well as information on their daily level of stress. Results show that transformational leader behaviour is significantly related to followers’ level of stress on a day-to-day basis. This relationship is mediated by team cooperation, but not by role conflict. The type of communication moderates this mediation framework. If only indirect means of communication are used, the negative indirect relation between transformational leader behaviour via team cooperation on daily stress is strengthened. The results are discussed in the context of leadership literature, and the implications for future research as well as practice are presented.     

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.     

Team Proactivity as a Linking Mechanism between Team Creative Efficacy,Transformational Leadership,and Risk‐Taking Norms and Team Creative Performance

Despite the growing body of research on creativity in team contexts, very few attempts have been made to explore the team‐level antecedents and the mediating processes of team creative performance on the basis of a theoretical framework. To address this gap, drawing on Paulus and Dzindolet's (2008) group creativity model, this study proposed team creative efficacy, transformational leadership, and risk‐taking norms as antecedents of team creative performance and team proactivity as an intervening mechanism between these relationships. The results of team‐level regression analyses conducted on the leaders and members of 103 Korean work teams showed that team creative efficacy and risk‐taking norms were positively associated with team creative performance. Furthermore, the relationships between team creative efficacy and team creative performance and between risk‐taking norms and team creative performance were mediated by team proactivity. These findings offer new insights regarding the antecedents and the mediator of creative performance in team contexts and important implications for theory and practice.     

When is educational specialization heterogeneity related to creativity in research and development teams? Transformational leadership as a moderator

The authors examined conditions under which teams' educational specialization heterogeneity was positively related to team creativity. Using a sample of 75 research and development teams, the authors theorized and found that transformational leadership and educational specialization heterogeneity interacted to affect team creativity in such a way that when transformational leadership was high, teams with greater educational specialization heterogeneity exhibited greater team creativity. In addition, teams' creative efficacy mediated this moderated relationship among educational specialization heterogeneity, transformational leadership, and team creativity. The authors discuss the implications of these results for research and practice.

Transformational and transactional leaderships,empowerment climate,and innovation performance: A multilevel analysis in the Chinese context

Innovation through creativity is an important factor in the success and competitive advantage of organizations. Theory and research suggest that both leadership and organizational climate have important consequences for individual creativity. However, researchers have rarely considered the interactive effects of leadership and organizational climate. This study taking a “Substitute for Leadership” perspective, develops and tests the idea that empowerment climate affect the relationship between leadership and followers' creative performance. Data were collected from 93 teams, including 465 team members and 93 team supervisors, in a large multinational company based in China. Hierarchical linear modelling was used to examine the hypothesized cross-level model. As expected, transformational leadership and team empowerment climate were positively related to subordinates' creative performance and transactional leadership was negatively related to subordinates' creative performance. In addition, the relationship between leadership and subordinates' creative performance was moderated by team empowerment climate. The study resulted in the implication of several major variables for explaining individual creativity in the Chinese context.     

Self‐Engagement Moderates the Mediated Relationship Between Organizational Constraints and Organizational Citizenship Behaviors Via Rated Leadership

We examined self‐engagement in job performance in a moderated mediation model where engagement moderated the relationship between organizational constraints and ratings of leadership effectiveness, and ratings of leadership effectiveness mediated the relationship between organizational constraints and organizational citizenship behaviors (OCBs). University employees representing diverse occupations completed measures of self‐engagement, organizational constraints, and leader effectiveness. Supervisors provided ratings of OCB. Tests of mediated moderation using random coefficient modeling revealed that leadership mediated the relationship between constraints and OCB for highly engaged employees. Results are discussed in terms of highly engaged workers being attuned to stressors in the work environment that may compromise performance, potentially blaming leaders for the presence of these obstacles, thus causing withdrawal of effort on nonessential performance tasks.     

Transformational Leadership and Creative Problem‐Solving: The Mediating Role of Psychological Safety and Reflexivity

Previous research has pointed to the importance of transformational leadership in facilitating employees' creative outcomes. However, the mechanism by which transformational leadership cultivates employees' creative problem‐solving capacity is not well understood. Drawing on theories of leadership, information processing and creativity, we proposed and tested a model in which psychological safety and reflexivity mediate the effect of transformational leadership and creative problem‐solving capacity. The results of survey data collected at three points in time indicate that transformational leadership facilitates the development of employees' creative problem‐solving capacity by shaping a climate of psychological safety conducive to reflexivity processes. However, the findings also indicate that psychological safety is related both directly and indirectly, through reflexivity, to employees' creative problem‐solving capacity. This study sheds further light on the ways in which transformational leaders help to develop and cultivate employees' capacity for creative problem‐solving.     

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.     

Leading by example: the case of leader OCB

The importance of leading by personal example or role modeling for effective leadership has been recognized in many leadership theories. However, leaders' ability to influence group behavior through exemplary behavior has received little attention in empirical work. This study explores leading by example through theoretical development and empirical testing of a moderated mediation model of the potential effects of leader organizational citizenship behavior (OCB). This model suggests that a leader's OCB may promote group OCB directly and indirectly by enhancing the group's belief that OCB is worthy. It also specifies the moderators of the direct and indirect effects of leader OCB on group OCB. Data from 683 members of 67 intact work groups, 67 group managers, and their supervisors support the hypothesized model. The theoretical and practical implications of these findings are discussed.     

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.     

Antecedents and Consequences of Creativity in Teams: When and How Leader Humility Promotes Performance via Team Creativity

The antecedents of team creativity and their effects on team task performance are explored in this study, with a particular focus on how leader humility promotes team creativity and when team creativity can be converted into performance. Hypotheses were tested via a multiple-source and time-lagged study with 341 employees and 104 teams from five different organizations in China. The results showed that leader humility promotes team creativity through team creative efficacy, and leader conscientiousness moderates this indirect effect. Furthermore, team creativity is more positively related to team task performance when teams are more future oriented. The theoretical contributions and management significance of these findings are discussed, followed by a discussion of limitations and directions for future research.

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.

Transformational leadership and customer service: A moderated mediation model of negative affectivity and emotion regulation

Integrating theories from leadership, emotion management, affectivity, and customer service, this study examines how transformational leadership leads to favourable customer intentions via the mediation of service employees' emotion regulation, job satisfaction, and their service performance and via the moderation of employee negative affectivity. Results obtained from data of 204 matched sets of managers, service employees, and customers show that the effect of transformational leadership on amplification of pleasant emotions was conditioned on service employees' negative affectivity. Employee service performance partially mediated the effect of job satisfaction on customer outcomes. Finally, overall results reveal that transformational leadership and amplification of pleasant emotions were more strongly related to the customer outcomes, as mediated through the intervening variables in the model, when negative affectivity was high than when negative affectivity was low. Results have implications for how service workers with negative affectivity can manage their emotions to achieve effective service outcomes through interactions with a leader, how the effect of transformational leadership can be bounded, and how transformational leadership and emotion regulation are relevant to customer service.     

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.     

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.
