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. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

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.

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 innovation: Integrating team climate principles.

Fostering team innovation is increasingly an important leadership function. However, the empirical evidence for the role of transformational leadership in engendering team innovation is scarce and mixed. To address this issue, the authors link transformational leadership theory to principles of M. A. West's (1990) team climate theory and propose an integrated model for the relationship between transformational leadership and team innovation. This model involves support for innovation as a mediating process and climate for excellence as a moderator. Results from a study of 33 research and development teams confirmed that transformational leadership works through support for innovation, which in turn interacts with climate for excellence such that support for innovation enhances team innovation only when climate for excellence is high.

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.

The ties that bind: The impact of leader-member exchange, transformational and transactional leadership, and distance on predicting follower performance.

The authors examined the linkages between leader-member exchange (LMX), transformational and transactional leadership, and physical distance in predicting performance of 317 followers over a 1-year period. Results from a partial least squares analysis revealed that LMX was related positively to transformational and contingent reward leadership and negatively to management-by-exception. LMX and active management-by-exception positively predicted follower performance, and physical distance moderated leadership-performance relationships. Transformational leadership produced significantly higher follower performance in close versus distant situations, whereas LMX produced high follower performance irrespective of physical distance between leaders and followers.

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.

The bright-side and the dark-side of CEO personality: Examining core self-evaluations, narcissism, transformational leadership, and strategic influence.

This article reports on an examination of the relationships between chief executive officer (CEO) personality, transformational and transactional leadership, and multiple strategic outcomes in a sample of 75 CEOs of Major League Baseball organizations over a 100-year period. CEO bright-side personality characteristics (core self-evaluations) were positively related to transformational leadership, whereas dark-side personality characteristics (narcissism) of CEOs were negatively related to contingent reward leadership. In turn, CEO transformational and contingent reward leadership were related to 4 different strategic outcomes, including manager turnover, team winning percentage, fan attendance, and an independent rating of influence. CEO transformational leadership was positively related to ratings of influence, team winning percentage, and fan attendance, whereas contingent reward leadership was negatively related to manager turnover and ratings of influence.

A multilevel study of leadership, empowerment, and performance in teams.

A multilevel model of leadership, empowerment, and performance was tested using a sample of 62 teams, 445 individual members, 62 team leaders, and 31 external managers from 31 stores of a Fortune 500 company. Leader-member exchange and leadership climate related differently to individual and team empowerment and interacted to influence individual empowerment. Also, several relationships were supported in more but not in less interdependent teams. Specifically, leader-member exchange related to individual performance partially through individual empowerment; leadership climate related to team performance partially through team empowerment; team empowerment moderated the relationship between individual empowerment and performance; and individual performance was positively related to team performance. Contributions to team leadership theory, research, and practices are discussed. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

The power of “we”: Effects of psychological collectivism on team performance over time.

We examined the influences of different facets of psychological collectivism (Preference, Reliance, Concern, Norm Acceptance, and Goal Priority) on team functioning at 3 different performance depictions: initial team performance, end-state team performance, and team performance change over time. We also tested the extent to which team-member exchange moderated the relationships between facets of psychological collectivism and performance change over time. Results from multilevel growth modeling of 66 teams (N = 264) engaged in a business simulation revealed differential effects across facets of psychological collectivism and across different performance measurements. Whereas facets concerned with affiliation (Preference and Concern) were positively related to initial team performance, reliance was negatively related to initial team performance. Goal Priority was a strong predictor of end-state performance. Team-member exchange moderated the relationship between performance change and 3 of the 5 facets of psychological collectivism (Preference, Reliance, Norm Acceptance). Implications for team composition and team training are discussed. (PsycINFO Database Record (c) 2011 APA, all rights reserved)     

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.

Information sharing and team performance: A meta-analysis.

Information sharing is a central process through which team members collectively utilize their available informational resources. The authors used meta-analysis to synthesize extant research on team information sharing. Meta-analytic results from 72 independent studies (total groups = 4,795; total N = 17,279) demonstrate the importance of information sharing to team performance, cohesion, decision satisfaction, and knowledge integration. Although moderators were identified, information sharing positively predicted team performance across all levels of moderators. The information sharing–team performance relationship was moderated by the representation of information sharing (as uniqueness or openness), performance criteria, task type, and discussion structure by uniqueness (a 3-way interaction). Three factors affecting team information processing were found to enhance team information sharing: task demonstrability, discussion structure, and cooperation. Three factors representing decreasing degrees of member redundancy were found to detract from team information sharing: information distribution, informational interdependence, and member heterogeneity.

The relation between leadership style and empowerment on job satisfaction of nurses

OBJECTIVE: The authors explore the relation between leadership style and empowerment and its effect on job satisfaction among the nursing staff of a regional medical center. BACKGROUND: Several empirical studies on transformational leadership-found that transformational leadership behaviors were positively related to work team success and leadership effectiveness. Transformational leadership processes have also been suggested to enhance followers' work-oriented values and shape the self-efficacies of followers. Employee empowerment may be influenced by the perception that the organization cares about its employees' well-being and that their work is valued. Empowering nurses may increase job satisfaction and improve patient care. Leadership style and empowerment influence job satisfaction among workers. METHODS: All nursing department staff were invited to complete a self-report questionnaire with no identifying information. Leadership style was measured using Bass's Multifactor Leadership Questionnaire, empowerment was measured with items from Spreitzer's Psychological Empowerment instrument, and job satisfaction was measured by Warr, Cook, and Wall's job satisfaction questionnaire. RESULTS: Both transformational and transactional leadership were positively related to job satisfaction, as was empowerment. Differences in the contributions of empowerment and leadership style in predicting job satisfaction for licensed and unlicensed workers was evident. CONCLUSION: Designing interventions that allow for the relative influence of leadership style as well as empowerment on varying classifications of nursing personnel may be a more effective strategy and have a greater effect on staff attitudes and behaviors.     

Leader-member exchange and member performance: A new look at individual-level negative feedback-seeking behavior and team-level empowerment climate.

From a basis in social exchange theory, the authors investigated whether, and how, negative feedbackseeking behavior and a team empowerment climate affect the relationship between leader-member exchange (LMX) and member performance. Results showed that subordinates' negative feedbackseeking behavior mediated the relationship between LMX and both objective and subjective in-role performance. In addition, the level of a team's empowerment climate was positively related to subordinates' own sense of empowerment, which in turn negatively moderated the effects of LMX on negative feedback-seeking behavior.

Exploring the dual-level effects of transformational leadership on followers.

We developed a dual-level transformational leadership scale to measure individual-focused behavior at the individual level and group-focused behavior at the group level, and we validated the scale using a sample of 203 members from 60 work groups in a Canadian company. Results show that individual-focused leadership behavior, at the individual level, was positively related to task performance and personal initiative; group-focused leadership behavior, at the group level, was positively associated with team performance and helping behavior. Implications for leadership theory and practice are offered. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Antecedents of team potency and team effectiveness: An examination of goal and process clarity and servant leadership.

Integrating theories of self-regulation with team and leadership literatures, this study investigated goal and process clarity and servant leadership as 3 antecedents of team potency and subsequent team effectiveness, operationalized as team performance and organizational citizenship behavior. Our sample of 304 employees represented 71 teams in 5 banks. Results showed that team-level goal and process clarity as well as team servant leadership served as 3 antecedents of team potency and subsequent team performance and team organizational citizenship behavior. Furthermore, we found that servant leadership moderated the relationships between both goal and process clarity and team potency, such that the positive relationships between both goal and process clarity and team potency were stronger in the presence of servant leadership.

The effects of transformational and change leadership on employees' commitment to a change: A multilevel study.

The effects of transformational leadership on the outcomes of specific change initiatives are not well understood. Conversely, organizational change studies have examined leader behaviors during specific change implementations yet have failed to link these to broader leadership theories. In this study, the authors investigate the relationship between transformational and change leadership and followers' commitment to a particular change initiative as a function of the personal impact of the changes. Transformational leadership was found to be more strongly related to followers' change commitment than change-specific leadership practices, especially when the change had significant personal impact. For leaders who were not viewed as transformational, good change-management practices were found to be associated with higher levels of change commitment.

Work Group Diversity and Group Performance: An Integrative Model and Research Agenda.

Research on the relationship between work group diversity and performance has yielded inconsistent results. To address this problem, the authors propose the categorization-elaboration model (CEM), which reconceptualizes and integrates information/decision making and social categorization perspectives on work-group diversity and performance. The CEM incorporates mediator and moderator variables that typically have been ignored in diversity research and incorporates the view that information/decision making and social categorization processes interact such that intergroup biases flowing from social categorization disrupt the elaboration (in-depth processing) of task-relevant information and perspectives. In addition, the authors propose that attempts to link the positive and negative effects of diversity to specific types of diversity should be abandoned in favor of the assumption that all dimensions of diversity may have positive as well as negative effects. The ways in which these propositions may set the agenda for future research in diversity are discussed. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Transforming service employees and climate: A multilevel, multisource examination of transformational leadership in building long-term service relationships.

This longitudinal field study integrates the theories of transformational leadership (TFL) and relationship marketing to examine how TFL influences employee service performance and customer relationship outcomes by transforming both (at the micro level) the service employees' attitudes and (at the macro level) the work unit's service climate. Results revealed that, at the individual level, managers' TFL was positively related to employee service performance, which, in turn, positively predicted customers' expressed intention to maintain a long-term service relationship with the service employee and manager-reported number of the employee's long-term customers measured 9 months later. In addition, the relationship between TFL and employee service performance was partially mediated by employee self-efficacy. Furthermore, store-level TFL was positively associated with store-level service climate, and service climate further enhanced the relationship between individual-level TFL and employee service performance.

Team reflexivity, development of shared task representations, and the use of distributed information in group decision making.

Decision-making groups often exchange and integrate distributed information to a lesser extent than is desirable for high-quality decisions. One important reason for this lies in group members’ understanding of the decision task—their task representations—specifically the extent to which they understand the importance of exchange and integration of information. The authors hypothesized that a group’s development of a (shared) understanding of the information elaboration requirements of their task is influenced by collective reflection on the task. When not all group members initially realize the importance of information elaboration, team reflexivity increases the degree to which the group understands the importance of information elaboration. In an experiment, the authors showed that team reflection fostered the development of task representations emphasizing information elaboration and subsequent information elaboration and decision quality. When all members initially already held representations emphasizing information elaboration, team reflection promoted elaboration and performance to a lesser degree.
