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.     

Five-factor model of personality and transformational leadership

This study linked traits from the 5-factor model of personality (the Big 5) to transformational leadership behavior. Neuroticism, Extraversion, Openness to Experience, and Agreeableness were hypothesized to predict transformational leadership. Results based on 14 samples of leaders from over 200 organizations revealed that Extraversion and Agreeableness positively predicted transformational leadership; Openness to Experience was positively correlated with transformational leadership, but its effect disappeared once the influence of the other traits was controlled. Neuroticism and Conscientiousness were unrelated to transformational leadership. Results further indicated that specific facets of the Big 5 traits predicted transformational leadership less well than the general constructs. Finally, transformational leadership behavior predicted a number of outcomes reflecting leader effectiveness, controlling for the effect of transactional leadership.     

Charismatic leadership,environmental dynamism,and performance

Most studies relating charismatic leadership to performance have limitations concerning selection of criterion measures and investigation of moderators. Therefore, this study examines relationships between charismatic leadership and multiple performance outcomes under different levels of environmental dynamism (i.e., level of environmental uncertainty, degree of technological change) and per type of Chief Executive Officer (firm owner versus managing director). Results revealed that charismatic leadership was positively related to common-source and multi-source perceptual performance outcomes (i.e., subordinates' positive work attitude) and to organization profitability, but unrelated to organization liquidity and solvency. The relationship between charismatic leadership and perceptual performance was stronger under conditions of environmental uncertainty than under conditions of environmental certainty. Furthermore, charismatic leadership was more strongly related to organization profitability for firm owners than for managing directors who do not own their firm. The results are discussed and several potentially fruitful avenues for future research on charismatic leadership and employee as well as organizational performance are presented.     

Transformational and transactional leadership: a meta-analytic test of their relative validity

This study provided a comprehensive examination of the full range of transformational, transactional, and laissez-faire leadership. Results (based on 626 correlations from 87 sources) revealed an overall validity of .44 for transformational leadership, and this validity generalized over longitudinal and multisource designs. Contingent reward (.39) and laissez-faire (-.37) leadership had the next highest overall relations; management by exception (active and passive) was inconsistently related to the criteria. Surprisingly, there were several criteria for which contingent reward leadership had stronger relations than did transformational leadership. Furthermore, transformational leadership was strongly correlated with contingent reward (.80) and laissez-faire (-.65) leadership. Transformational and contingent reward leadership generally predicted criteria controlling for the other leadership dimensions, although transformational leadership failed to predict leader job performance.     

Transformational leadership,diversity climate,and job satisfaction in selected South African companies

This study investigated the relationship between transformational leadership, diversity climate, and job satisfaction in a selection of South African companies. Participants were a convenience sample of 263 employees from the Gauteng Province (white?=?69.3%). They completed measures for transformational leadership, diversity climate, and job satisfaction. Structural Equation Modelling analysis revealed transformational leadership to directly predict job satisfaction and diversity climate, and to mediate the relationship between transformational leadership and job satisfaction. Moreover, transformational leadership directly and positively predicted quality of workplace diversity climate. Future leaders and managers should leverage an organisation’s diversity climate for job satisfaction applying transformational leadership strategies.     

Predicting unit performance by assessing transformational and transactional leadership

How do leadership ratings collected from units operating under stable conditions predict subsequent performance of those units operating under high stress and uncertainty? To examine this question, the authors calculated the predictive relationships for the transformational and transactional leadership of 72 light infantry rifle platoon leaders for ratings of unit potency, cohesion, and performance for U.S. Army platoons participating in combat simulation exercises. Both transformational and transactional contingent reward leadership ratings of platoon leaders and sergeants positively predicted unit performance. The relationship of platoon leadership to performance was partially mediated through the unit's level of potency and cohesion. Implications, limitations, and future directions for leadership research are discussed.     

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.     

Leadership predictors of innovation and task performance: Subordinates' self‐esteem and self‐presentation as moderators

This study examined self‐related subordinate variables as moderators of relationships between supervisors' leadership behaviours (transformational as well as active‐corrective transactional leadership) and subordinates' innovative behaviour and task performance. Based on behavioural plasticity and self‐monitoring theory, we hypothesized that these associations would be moderated by subordinates' organization‐based self‐esteem and by their propensity to modify self‐presentation, a major facet of the self‐monitoring construct. Field survey data (N=161) collected in research and development, marketing and human resources departments of several German companies revealed that transformational leadership positively predicted both criteria, whereas active‐corrective transactional leadership negatively predicted innovation. As hypothesized, transformational leadership related more strongly and positively to innovation for subordinates low in organization‐based self‐esteem. When subordinates were low in self‐presentation propensity, active‐corrective transactional leadership was negatively, and transformational leadership was positively associated with task performance.     

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.     

Bases of social power,leadership styles,and organizational commitment

Affective organizational commitment reflects the extent to which organizational members are loyal and willing to work toward organizational objectives (Meyer & Allen, 1997). In particular, affective organizational commitment holds very important implications at all organizational levels (e.g., turnover rates, performance, and citizenship behavior). Whereas previous research has evinced the positive influence of transformational and charismatic leadership styles on affective commitment toward the organization (Bass & Avolio, 1994), little is known with regard to the nature of this relationship. In line with the interpersonal power/interaction model, the present investigation aimed to investigate the mechanism at play between transformational leadership style and affective organizational commitment. Specifically, we hypothesized that transformational leadership style would increase affective organizational commitment through its effect on willingness to comply with soft bases of power. In two studies, we subjected the foregoing hypotheses to empirical scrutiny. In Study 1, the proposed mediation model was empirically supported with Italian employees in the public sector. Attesting to the robustness of our findings, Study 2 replicated the findings of Study 1 with Italian employees from the public and private sectors. In addition, Study 2 replicated Study 1 using a different measure of transformational leadership. Both Study 1 and Study 2 provided results consistent with our hypotheses. Specifically, the present paper reports empirical evidence that (1) the more participants report having a transformational leader, the more willing they become to comply with soft (but not harsh) power bases, (2) in turn, greater willingness to comply with soft (but not harsh) power bases increases one's affective organizational commitment. These findings provide additional support for the interpersonal power/interaction model and pave the way for new research directions.     

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.     

HR practices as a mediator between organizational culture and transformational leadership: Implications for employee performance

Studies pertaining to human resource (HR) management in India have revealed a variety of factors that significantly affect employee performance not the least of which are organizational culture and leadership issues. The present study posits firm level HR practices as a mediator between organizational culture and transformational leadership whose outcomes are hypothesized as lower levels of individual employees’ intention to quit the organization and higher level of performance. For this purpose, data were collected from mangers/executives (N=357) and subjected to multivariate analysis. The results reveal that culture and leadership are significant predictors of intention to quit and employee performance. The results also show that HR practices are important mediators in transmitting the influence of the predictor variables to the criterion variables.     

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.     

Gender makes the difference: The moderating role of leader gender on the relationship between leadership styles and subordinate performance

Using a predominantly male research and development (R&D) sample and a predominantly female customer service personnel sample, we investigated how authoritarian and benevolent leadership styles interact with leader gender to influence subordinate performance (i.e., task performance, citizenship behavior, and creativity). Our research extends role congruity theory (Eagly & Karau, 2002) by adopting  and  attribution principles to offer a more comprehensive framework for explaining how leader gender affects the impact of leadership styles on subordinate performance. Our results suggest that the negative relationship between authoritarian leadership and subordinate performance is stronger for female than for male leaders and that the positive relationship between benevolent leadership and subordinate performance is stronger for male than for female leaders. Accordingly, in addition to leaders’ engaging in gender-role congruent behaviors, a useful strategy is to adopt behaviors that are perceived as a positive deviation from their gender role.     

The utility of transactional and transformational leadership for predicting performance and satisfaction within a path‐goal theory framework

In a test of hypotheses derived from the integration of principles of path‐goal theory ( House, 1996 ) and transformational leadership theory ( Bass, 1985 ), data collected from 179 high school teachers and their principals were examined with hierarchical regression analysis. Augmentation analysis indicated that transactional leadership had a stronger role in explaining unique criterion variance beyond the contribution of transformational leadership, than did transformational leadership relative to transactional leadership. In addition, both the transactional and transformational leadership had a negative interactive relationship for predicting the outcome of performance, such that leader vision and leader intellectual stimulation were more positively correlated with employee performance when leader use of contingent reward was low. These augmentation effects, in conjunction with the findings of negative moderation, suggest that transactional leadership may have greater potential predictive value than previously assumed.     

Follower moral reasoning influences perceptions of transformational leadership behavior

Transformational leadership reflects charismatic, but ethical, influence on followers. However, leadership ultimately occurs through the perceptual and attribution processes within followers. Accordingly, the perception and evaluation of transformational leadership is likely to be influenced by followers' moral reasoning, which is the ability that allows individuals to identify and interpret ethically‐salient issues in social environments. As predicted by social‐cognitive principles of self‐schemas, observers' moral reasoning positively related to the perception and positive evaluation of transformational leadership behavior, but not to positive affective reactions towards that behavior. These same relationships did not occur for the perception and evaluation of transactional leadership behavior. Implications for whistle‐blowing behavior, organizational ethics, and the measurement of transformational leadership are discussed.     

Development and test of a model linking safety-specific transformational leadership and occupational safety

The authors developed, tested, and replicated a model in which safety-specific transformational leadership predicted occupational injuries in 2 separate studies. Data from 174 restaurant workers (M age = 26.75 years, range = 15-64) were analyzed using structural equation modeling (LISREL 8; K. G. J?reskog & D. S?rbom, 1993) and provided strong support for a model whereby safety-specific transformational leadership predicted occupational injuries through the effects of perceived safety climate, safety consciousness, and safety-related events. Study 2 replicated and extended this model with data from 164 young workers from diverse jobs (M age = 19.54 years, range = 14-24). Safety-specific transformational leadership and role overload were related to occupational injuries through the effects of perceived safety climate, safety consciousness, and safety-related events.     

Relations and effects of transformational leadership: a comparative analysis with traditional leadership styles

This study has two main goals: (a) to compare the relationship between transformational leadership and other important leadership styles (i.e., democratic versus autocratic or relations- and task-oriented leadership) and (b) to compare the effects of transformational leadership and the other styles on some important organizational outcomes such as employees' satisfaction and performance. For this purpose, a sample of 147 participants, working in 35 various work-teams, was used. Results show high correlations between transformational leadership, relations-oriented, democratic, and task-oriented leadership. On the other hand, according to the literature, transformational leadership, especially high levels, significantly increases the percentage of variance accounted for by other leadership styles in relevant organizational outcome variables (subordinates' performance, satisfaction and extra effort).     

The two faces of transformational leadership: empowerment and dependency

Followers' identification with the leader and the organizational unit, dependence on the leader, and empowerment by the leader are often attributed to transformational leadership in organizations. However, these hypothesized outcomes have received very little attention in empirical studies. Using a sample of 888 bank employees working under 76 branch manages, the authors tested the relationships between transformational leadership and these outcomes. They found that transformational leadership was positively related to both followers' dependence and their empowerment and that personal identification mediated the relationship between transformational leadership and followers' dependence on the leader, whereas social identification mediated the relationship between transformational leadership and followers' empowerment. The authors discuss the implications of these findings to both theory and practice.
