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.

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.

Organizational citizenship behavior : Comparing perspectives of supervisors and subordinates across four international samples

A total of 431 independent supervisor and subordinate dyads from the United States, Australia, Japan, and Hong Kong evaluated the perceived job role boundary of the subordinate ;, Participants rated the degree to which they agreed that the behavior described in the organizational citizenship behavior (OCB) scale developed by P. M. Podsakoff, S. B. MacKenzie, R. H. Moorman, and R. Fetter (1990) was an expected part of the subordinates job. Each supervisor was paired with only one subordinate, and all participants held the same jobs in the same company but with branches in these 4 nations. The scale used was found to have conceptual equivalence across all subsamples. Results indicated that supervisors had broader definitions of job roles than subordinates. Participants from Hong Kong and Japan were also more likely to regard some categories of OCB as an expected part of the job than were participants from the United States and Australia.

Participative Decision Making and Employee Performance in Different Cultures: The Moderating Effects of Allocentrism/Idiocentrism and Efficacy

The relationship between perceived participative decision making and employee performance was examined in matched samples of employees from the Hong Kong and U.S. branches of one organization. Self...

Collective efficacy versus self-efficacy in coping responses to stressors and control: a cross-cultural study.

This study examined how cultural differences and efficacy perceptions influence the role of job control in coping with job demands. Perceiving higher control mitigated the effects of demands on psychological health symptoms and turnover intentions only among American bank tellers reporting high job self-efficacy. Among American tellers reporting low job self-efficacy, perceived control exacerbated the effects of demands. However, in a matched Hong Kong sample, collective efficacy interacted in the same way with control and demands as job self-efficacy had in the American sample. These differences appear to be explained by the individual attributes of idiocentrism and allocentrism that are linked to the societal norms of individualism and collectivism, respectively.

HOW SIMILARITY TO PEERS AND SUPERVISOR INFLUENCES ORGANIZATIONAL ADVANCEMENT IN DIFFERENT CULTURES

This study tested hypotheses concerning how similarity of personality traits between promotion candidates and their peers and supervisors influences promotion decisions in different work unit cultu...

Psychological contract breaches, organizational commitment, and innovation-related behaviors: a latent growth modeling approach.

This study examined the relationships among psychological contract breaches, organizational commitment, and innovation-related behaviors (generating, spreading, implementing innovative ideas at work) over a 6-month period. Results indicate that the effects of psychological contract breaches on employees are not static. Specifically, perceptions of psychological contract breaches strengthened over time and were associated with decreased levels of affective commitment over time. Further, increased perceptions of psychological contract breaches were associated with decreases in innovation-related behaviors. We also found evidence that organizational commitment mediates the relationship between psychological contract breaches and innovation-related behaviors. These results highlight the importance of examining the nomological network of psychological contract breaches from a change perspective.

Do Customers and Employees Enjoy Service Participation? Synergistic Effects of Self- and Other-Efficacy

Extant research confirms the importance of value cocreation through customer participation (CP), but relatively little is known about whether and how it creates an enjoyable experience for customers and service employees and the consequential outcomes of this positive affective experience. This study applies the concept of flow as an overarching framework and draws theoretical support from social cognitive theory, particularly its extension (i.e., the conceptual model of relational efficacy beliefs), to examine how customers and employees derive enjoyment from CP conditional on their perceived efficacy of themselves (self-efficacy [SE]) and their partners (other-efficacy [OE]) in financial services. Empirical results from 223 client–financial adviser dyads confirm that participation enjoyment, in addition to economic and relational values, mediates the impact of CP on participants’ satisfaction evaluations, with SE positively moderating CPs impact on participation enjoyment. The synergistic effect of SE and OE on participation enjoyment also differs for clients versus financial advisers: Even incongruent levels of SE and OE can enhance participation enjoyment as long as they help validate role expectations of the respective participants.

Theories of Job Stress and the Role of Traditional Values: A Longitudinal Study in China

This study examines how traditionality influences the relationships between job stressors and health. A sample of 496 Chinese employees provided longitudinal questionnaire data, and their health was assessed by collecting blood samples and monitoring blood pressure. The results indicated that the positive relationship between job control and health was stronger among the less traditional workers, whereas the positive relationship between distributive justice and health was stronger among the more traditional workers. Furthermore, traditionality moderated the interactive effects of job demands and perceived control/justice on health. Perceiving higher control mitigated the effects of job demands on upper respiratory infections among low traditionalists, but it exacerbated the effects among the high traditionalists. Perceptions of higher justice mitigated the effects of job demands on emotional exhaustion and immunoglobulin A for high traditionalists but not for low traditionalists. These results suggest that, in the relationship between job demands and psychological and physiological health, concern for equity is an important moderator for individuals with more traditional values, whereas perceived personal control is salutary for health primarily among people with less traditional values.

Improving group decisions by better pooling information: A comparative advantage of group decision support systems

This study compared a group decision support system (GDSS) with face-to-face (FTF) group discussion on characteristics of information exchange and decision quality. Participants given conflicting information tended to share more of their unique data and engaged in more critical argumentation when using the GDSS than when meeting FTF. Conversely, when information was consistent among members, there were no such differences between FTF and GDSS groups. The GDSS groups significantly outperformed the FTF groups in agreeing on the superior hidden profile candidate, especially when there was a lack of prediscussion consensus. Individual-level analyses revealed that members of GDSS groups that did not have a prediscussion consensus tended to experience stronger preference shifts toward the groups consensus decision.
