The effects of leadership style on stress outcomes

The present study manipulated transformational and transactional leadership styles to examine their influence on individuals' performance on a stressful task, and on perceived social support, self-efficacy beliefs, emotions, and stressor appraisals. In addition, this study examined whether these variables mediated the relationship between leadership style and performance. Two hundred fourteen participants viewed video instructions for a stressful task presented by an actor depicting one of three leadership styles (transformational, transactional-contingent reward, and transactional-management by exception). Participants' psychological, emotional, and motivational responses to the videos were assessed prior to their engagement with the task. The transformational leadership condition was associated with enhanced task performance, higher social support perceptions, greater efficacy beliefs, lower negative affect, and lower threat appraisals compared to the transactional conditions. Causal modeling revealed that leadership style had a direct, rather than indirect, effect on task performance. The present research extends leadership research by providing an experimental evaluation of the costs/benefits of transformational and transactional leadership under stressful task conditions. Some of the results parallel those from correlational field studies, thus corroborating transformational leadership theory while other results diverge from theory, but present opportunities for future research.     

Communication and trust are key: Unlocking the relationship between leadership and team performance and creativity

Considerable theoretical and empirical work has identified a relationship between transformational leadership and team performance and creativity. The mechanisms underlying this link, however, are not well understood. To identify the intervening processes inherent in this relationship, we experimentally manipulated the leadership style assigned to 44 teams taking part in a resource-maximization task. Teams were exposed either to a leader using inspirational motivation, intellectual stimulation, or a control condition. Our findings reveal important differences between leadership styles in communication and team outcomes (objective task performance and creativity). These results suggest that different dimensions of transformational leadership should be emphasized depending on the outcome sought. In addition, our results provide evidence for a sequential mediation model where leadership influences team outcomes through overall team communication and trust in teammates. This study suggests mechanisms by which transformational leaders may impact team outcomes, which has implications for team building and leadership training.     

Education TEAM-SIZE EFFECTS ON BUSINESS GAME PERFORMANCE AND DECISION-MAKING BEHAVIORS

The effects of various decision-making team sizes in a complex business game were studied. Firm size was associated with nonlinear performance results and decision curves resulting in differential learning outcomes, learning sources, attrition rates, and decisionmaking behaviors. A three-member format produced the highest learning levels while two-member firms experienced only marginally significant knowledge increases. Single-member firms experienced the most bankruptcies and dropouts. A contingency view of gaming effectiveness is suggested.     

Transformational leadership,job satisfaction,and team performance: A multilevel mediation model of trust

In spite of calls for deliberate differentiation between individual and team levels of analysis, leadership research based on well-grounded theory referring to multiple levels is scarce. We seek to fill this gap by analyzing the relations between transformational leadership, trust in supervisor and team, job satisfaction, and team performance via multilevel analysis. Results are based on a sample of 360 employees from 39 academic teams. Transformational leadership was positively related to followers' job satisfaction at individual as well as team levels of analysis and to objective team performance. The relation between individual perceptions of supervisors' transformational leadership and job satisfaction was mediated by trust in the supervisor as well as trust in the team. Yet, trust in the team did not mediate the relationship between team perceptions of supervisors' transformational leadership and team performance. Implications for theory and research of leadership at multiple levels as well as for practice are discussed.     

Leadership effects on organizational climate and financial performance: Local leadership effect in chain organizations

Leadership research to date has mainly focused on leaders' subjective effects. In this study, we examine the effect of different leadership styles on two financial measures of organizational performance and three measures of organizational climate in 50 supermarket stores of a large supermarket chain in the Netherlands. Our findings show a clear relationship of local leadership with the financial performance and organizational climate in the stores. The findings also show that the leadership styles have differential effects. Charismatic leadership and consideration have a substantial effect on climate and financial performance in the small stores, suggesting the relevance of personal leadership of the store manager in these small stores. Initiating structure leadership had no effect on financial results or organizational climate, either in the small stores or in the large stores. Based on these findings, we have formulated some avenues for further research.     

Different ways lead to ambidexterity: Configurations for team innovation across China,India, and Singapore

In this paper, we transfer the ambidexterity theory of leadership for innovation to a cross-cultural context. We develop a configurational model to explore how combinations of opening leadership, closing leadership, and team initiative differently affect team innovation performance in different cultures. Applying an Asia-centric perspective, our study analyzes cross-cultural heterogeneity of team innovation processes across China, India, and Singapore. Our fuzzy-set qualitative comparative analysis (fsQCA) illuminates cultural differences and the configurational nature of how leadership and team behaviors work together in promoting team innovation performance. We found that configurations for team innovation performance differ across countries, such that an innovation-yielding configuration in one country may be ineffective in another country. Moreover, our findings suggest that alternative, equifinal configurations of leadership and team initiative, rather than just one optimal pathway, are associated with high team innovation performance; and high-performance configurations and low-performance configurations are asymmetric and therefore imply non-linearity of the relationships. The findings provide implications for managers in different cultural contexts as they help identify culture-specific action repertoires to manage innovation processes and promote innovation performance.     

Observing leadership as behavior in teams and herds – An ethological approach to shared leadership research

Both Shared Leadership Theory and evolutionary theories of leadership emphasize the role of team-level patterns of influence on team or group success. Yet, most of the empirical work on the effects of shared leadership assesses the concept through patterns of subjective perceptions of leadership and behavior. Although these studies give us important insights, subjective perceptions of leadership are prone to biases. In this paper, we draw on evolutionary theories of the development of leadership in groups and argue that group-level patterns of observable behavior have a direct effect on team outcomes above and beyond patterns of leadership and behavior perceptions. On the basis of a brief review of ethological assessment methods of leadership in animal groups, we derive implications for team leadership research methods to test hypotheses on team-level influence patterns and performance. Emphasizing the role of influence in terms of interpersonal behavior we formulate implications for the assessment and analysis of verbal and nonverbal behavior in teams. Finally, we discuss how technological advances may be utilized to promote behavioral observations in team leadership research.     

The influence of follower mood on leader mood and task performance: An affective,follower-centric perspective of leadership

Based on the notion that leadership involves affective exchange (Dasborough, Ashkanasy, Tee & Tse, 2009), we hypothesize that a leader's mood and task performance can be determined in part by follower mood displays. In two laboratory experiments, leaders supervised teams where the team members were confederates instructed to display positive or negative moods. Results were that followers' mood influenced leader mood and task performance. Moreover, leaders of positive mood followers were judged to have performed more effectively and expediently than leaders of followers who expressed negative mood states. We replicated these findings in Study 2 and found further that leaders high on neuroticism performed less effectively than their low neuroticism counterparts when interacting with negative-mood followers. Collectively, by demonstrating that follower moods influence leader affect and behaviors, our studies provide support for a core element of the Dasborough et al. (2009) reciprocal affect theory of leadership.     

Developmental stability and leadership effectiveness

Developmental stability is the degree to which we can withstand environmental or genetic stressors during development. Fluctuating asymmetry (FA), concerns the extent to which the right and left side of the body is asymmetrical and is one way to measure developmental stability. Two studies were carried out that examined both the predictive value of leader FA with leadership behaviors and its role in facilitating group performance. The first study examined the hypothesis that a leader's FA is correlated with scores on the Multifactor Leadership Questionnaire (MLQ). The results revealed individuals with a more asymmetrical morphology scored higher on the transformational, but not transactional, dimensions of leadership behavior. A second study examined the hypothesis that asymmetrical morphology and leadership effectiveness would share a positive relationship. In this study participants who led a business game exercise, revealed a positive relationship between FA and self-reported well-being and task satisfaction. Importantly, there was also a positive correlation between the leader's FA score and group performance. The role that developmental stability may play in leadership effectiveness is discussed in the wider context of evolutionary psychology.

Conceptualizing leadership perceptions as attitudes: Using attitude theory to further understand the leadership process

Leadership is one of the most examined factors in relation to understanding employee well-being and performance. While there are disparate approaches to studying leadership, they share a common assumption that perceptions of a leader's behavior determine reactions to the leader. The concept of leadership perception is poorly understood in most theoretical approaches. To address this, we propose that there are many benefits from examining leadership perceptions as an attitude towards the leader. In this review, we show how research examining a number of aspects of attitudes (content, structure and function) can advance understanding of leadership perceptions and how these affect work-related outcomes. Such a perspective provides a more multi-faceted understanding of leadership perceptions than previously envisaged and this can provide a more detailed understanding of how such perceptions affect outcomes. In addition, we examine some of the main theoretical and methodological implications of viewing leadership perceptions as attitudes to the wider leadership area. The cross-fertilization of research from the attitudes literature to understanding leadership perceptions provides new insights into leadership processes and potential avenues for further research.     

The shared leadership of teams: A meta-analysis of proximal,distal, and moderating relationships

The current meta-analysis examines the relationship between shared leadership and team performance. It also assesses the role of team confidence (i.e., collective efficacy and team potency) in this relationship. Mediation analyses supported the hypothesis that team confidence partially mediates the effects of shared leadership on team performance. We also found support for the notion that shared leadership explains unique variance in team performance, over and above that of vertical leadership. Furthermore, a variety of substantive continuous and categorical variables were investigated as moderators of the shared leadership–team performance relationship. Specifically, the relationship between shared leadership and team performance was moderated by task interdependence, team tenure, and whether performance was objectively versus subjectively measured. Finally, results suggest that the approach used when measuring shared leadership can also play a role in the observed validity. Theoretical and practical implications of these findings are discussed.     

The servant leadership advantage: When perceiving low differentiation in leader-member relationship quality influences team cohesion,team task performance and service OCB

How does servant leaders' unique ability to place each follower's needs above their own influence relationships between followers and impact their collective performance? In a study that integrates principles of servant leadership with the social comparison theoretical framework, we tested a group-level model to examine how servant leadership induces low perceived differentiation in leader-member relationship quality (perceived LMX differentiation) within a group, which strengthens team cohesion and in turn positively influences team task performance and service-oriented organizational citizenship behaviors (service OCB). Our sample comprised 229 employees nested in 67 work teams. Structural equation modeling results indicate that servant leadership significantly predicts low perceived LMX differentiation; perceived LMX differentiation is strongly related to team cohesion such that the lower the perceived differentiation, the stronger the team's cohesiveness. And, team cohesion is also strongly related to both the team's task performance and service OCB. Perceived LMX differentiation and team cohesion mediate the effect of servant leadership on both team task performance and service OCB.     

Task Design,Team Context,and Psychological Safety: An Empirical Analysis of R&D Projects in High Technology Organizations

High technology organizations need to develop new products or processes that address the dual goals of exploration and exploitation. The competing viewpoints and the asymmetric nature of market returns associated with these goals in R&D projects can heighten stress levels among project team members and reduce their psychological safety. While current research calls for greater focus on task design for improving psychological safety, we know little about how team contextual factors affect this relationship. This study develops and tests a conceptual framework that examines the moderating role of R&D team contextual factors, namely, relative exploration and project‐organization metric alignment on the relationship between a key task design variable, namely, team autonomy, and psychological safety. Relative exploration captures the extent to which exploration goals are emphasized over exploitation goals in an R&D project, while project‐organization metric alignment measures the extent to which project metrics are aligned with broader organizational metrics. Furthermore, we examine the performance consequences of psychological safety in R&D projects. The empirical analysis is conducted using primary data collected from multiple informants across 110 R&D projects in 34 high technology business units. Our results indicate that relative exploration and project‐organization metric alignment have contrasting moderating effects. Furthermore, the effect of psychological safety on project performance is found to be indirect and mediated through team turnover. Implications of the study findings, limitations, and directions for future research are discussed.     

Inclusive leadership and team innovation: The role of team voice and performance pressure

In today's complex and rapidly changing business environment, team innovation is increasingly critical to the survival and success of organizations. Although the relevant literature highlights the importance of leadership in team innovation, previous studies have mainly focused on transformational leadership and have yielded inconsistent results. To address this void, this study integrates the goal-setting theory into the input-process-output framework and proposes a moderated mediation model to examine the relationship between inclusive leadership and team innovation. The results of hierarchical regression analysis from two survey-based field studies in China demonstrated that team voice mediated the relationship between inclusive leadership and team innovation and performance pressure moderated the direct relationship between inclusive leadership and team voice as well as the indirect relationship between inclusive leadership and team innovation via team voice such that the relationships were stronger when performance pressure was high.     

研发团队共享领导力行为的产生和对创新绩效的作用：基于垂直领导力的影响

 共享领导力是提高多元性、知识型的组织绩效的有效方式，但已有对研发组织领导力理论的研究大都侧重于垂直领导力对创新的影响，对共享领导力关注不足，而共享领导力作为一种随着团队发展而动态形成的领导力类型，已被证明是提高多元性、知识型组织绩效的有效方式；目前将共享领导力作为整体概念的研究思路能从宏观视角把握其作用机制，但不足以从微观层面揭示共享领导力的动态性的产生和作用。        基于领导力行为理论，从7个行为维度对共享领导力和垂直领导力进行解构，考虑垂直领导力的影响，从微观层面研究共享领导力的产生及对创新绩效的作用。运用访谈和参与性观察对4个研发团队进行全生命周期数据收集，通过多案例研究方法和规范的质性分析技术探究共享领导力行为在团队不同发展阶段的形成过程，以及垂直领导力行为对该形成过程的影响。区分创新绩效中的过程绩效、产品绩效和学习绩效，进一步揭示共享领导力和垂直领导力在促进不同创新绩效过程中发挥的不同作用。        研究结果表明，共享领导力不同行为的产生既直接依赖于垂直领导力，又通过依存环境间接依赖于垂直领导力；共享领导力的不同行为并非一次性形成，而是分别产生于团队生命周期的不同阶段，即在团队构建期首先形成跨边界领导行为，在成员磨合期形成激励行为和关怀行为，在规范执行期形成授权行为和变革领导行为；共享领导力行为的这种动态性决定了其直接作用于团队创新的学习绩效和产品绩效，对过程绩效没有直接作用，而垂直领导力行为则对过程绩效具有直接促进作用，并通过共享领导力间接作用于学习绩效。        在理论层面，从共享领导力行为角度分析其产生和作用，从微观层面挖掘其动态特性，解释了共享领导力和垂直领导力在促进创新绩效过程中的替代和互补关系，从而完善共享领导力的动态概念理论，也为后续的动态研究提供新思路。在实践层面，为研发团队管理中依据团队不同阶段和不同类型的创新绩效需求发展不同的共享领导力行为提供理论支持。     

Leadership clarity and team innovation in health care

The relationships among leadership clarity (i.e., team members' consensual perceptions of clarity of and no conflict over leadership of their teams), team processes, and innovation were examined in health care contexts. The sample comprised 3447 respondents from 98 primary health care teams (PHCTs), 113 community mental health teams (CMHTs), and 72 breast cancer care teams (BCTs). The results revealed that leadership clarity is associated with clear team objectives, high levels of participation, commitment to excellence, and support for innovation. Team processes consistently predicted team innovation across all three samples. Team leadership predicted innovation in the latter two samples, and there was some evidence that team processes partly mediated this relationship. The results imply the need for theory that incorporates clarity and not just style of leadership. For health care teams in particular, and teams in general, the results suggest a need to ensure leadership is clear in teams when innovation is a desirable team performance outcome.     

Shared leadership performance relationship trajectories as a function of team interventions and members' collective personalities

We used longitudinal data from 205 members of 53 student teams who competed in a complex business simulation over 10 weeks to test: (1) whether shared leadership and performance were related reciprocally over time; (2) the relative magnitude of those relationships; and (3) whether a shared leadership intervention changes those relationships. We also considered the influence of team members' mean level personality to account for compositional effects. As anticipated, shared leadership and performance were related positively and reciprocally over time. Moreover, the shared leadership to performance relationship grew stronger and positive whereas the performance to shared leadership relationship remained fairly consistent over time. As expected, the intervention positively related to the trajectory of shared leadership. Finally, we did not find evidence for the hypothesized relationships of personality on shared leadership nor the strength of the intervention.     

Transformational leadership in context: Face-to-face and virtual teams

This experimental study examined transformational leadership in the context of traditional teams using face-to-face communication and virtual teams using computer-mediated communication. Thirty-nine leaders led both face-to-face and virtual teams. Repeated-measures analyses revealed similar mean levels of transformational leadership in both team types; however, leader rank order varied across team type. Post hoc analyses revealed that the most effective leaders where those who increased their transformational leadership in virtual teams. Furthermore, analyses at the team level revealed that the effect of transformational leadership on team performance was stronger in virtual than in face-to-face teams. Team-member ratings of transformational leadership were equally linked to project satisfaction in face-to-face and virtual teams. Considered as a whole, our results suggest that transformational leadership has a stronger effect in teams that use only computer-mediated communication, and that leaders who increase their transformational leadership behaviors in such teams achieve higher levels of team performance.     

Charismatic leadership and task feedback: A laboratory study of their effects on self-efficacy and task performance

This article examines the interactive effects of two different leadership styles (charismatic and noncharismatic) and three types of task feedback (internal, external, and no feedback) on individuals' self-efficacy and performance quality over four trials of a manufacturing task. Ninety-nine graduate students manufactured electrical wiring harnesses under the direction of either a charismatic or noncharismatic leader (an experimental confederate). Participants exposed to the charismatic leader had similar task performance regardless of task feedback condition, while participants exposed to the noncharismatic leader differed in their task performance depending on whether or not they received task feedback. Self-efficacy mediated the effect of task feedback and its interaction with charismatic leadership on performance. Explanations and implications of the results are discussed.
