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.     

Trait conscientiousness,leader‐member exchange,job satisfaction and organizational citizenship behaviour: A test of an integrative model

Competing theoretical models were tested, linking organizational citizenship behaviour (OCB) to trait conscientiousness, job satisfaction and leader‐member‐exchange (LMX) quality. Meta‐analytic structural equation modelling results provide strongest support for a model wherein more conscientious employees display more OCB, which enhances LMX quality, leading to greater job satisfaction. In‐turn, employees reciprocate their higher job satisfaction by demonstrating more OCB. Beyond supporting the view that OCB represents employee reciprocation for the satisfying job experiences typically stemming from higher‐quality LMX, our findings help to legitimize the notion that OCB may be used, particularly by more conscientious employees, as a means of nurturing higher‐quality LMX and to gain access to more satisfying job experiences.     

Transformational Leadership and Organisational Citizenship Behaviour: A Moderated Mediation Model of Leader‐Member‐Exchange and Subordinates' Gender

Transformational leadership (TL) enhances follower Organizational Citizenship Behavior (OCB) as mediated by leader‐member exchange (LMX). However, the strength of the positive associations among TL, LMX and OCB is subject to significant variability. Accordingly, we draw on several theories (self‐identity, role congruency, self‐concept, and social exchange) to propose that followers' gender moderates the relationships between all three of these variables. We argue differences in societal expectations and/or underlying motivation combine to make leadership of lesser importance to OCB among females than males. Using 202 supervisor‐subordinate dyads from Taiwan, a moderated mediation model of TL‐LMX‐OCB, with subordinate gender as a moderator, was tested. As hypothesised, each of the positive associations among TL, LMX and OCB were weaker for females than for males, thus accounting for some of the variability in the strength of the associations typically observed. Relatedly, although LMX fully mediated the TL‐OCB relationship in the entire sample, this effect was not observed among female subordinates. Further research is required to assess the degree to which these findings apply beyond the Confucian Asian societal cluster.     

A Structural Equation Model of the Effects of Negative Affectivity,Leader-Member Exchange,and Perceived Job Mobility on In-role and Extra-role Performance: A Chinese Case

In this paper, we contrast the effects of leader-member exchange (LMX) with the effects of perceived job mobility on in-role performance and organizational citizenship behavior (OCB). We further model negative affectivity as the antecedent of both LMX and perceived job mobility and suggest that LMX and perceived job mobility mediated the relationship between negative affectivity and performance. We obtained matching data from supervisor and subordinates in a major battery manufacturing company in southern China. Subordinates provided the negative affectivity, perceived job mobility, and LMX assessment, and their immediate supervisors provided the in-role performance and OCB assessment. Results from a structural equation analysis show that both LMX and perceived job mobility predicted OCB. Instead of being a direct antecedent of OCB, the relationship between negative affectivity and OCB is found to be mediated by LMX and perceived job mobility. Theoretical implications of the results are discussed.     

Differences between follower and dyadic measures of LMX as mediators of emotional intelligence and employee performance,well-being,and turnover intention

Both leader and follower emotional intelligence (EI) have been posited in the literature to influence leader–member exchange (LMX). We collected data from 203 independent leader–follower dyads working in the insurance industry in Malaysia and examined relationships between leader and follower trait-EI and follower outcomes mediated through LMX. We added a further dimension to our study by comparing results using follower and then a dyadic measure of LMX. We found that leader EI predicted a dyadic measure of LMX, whilst only follower EI predicted a follower measure of LMX. As hypothesized, leader EI had both direct and indirect effects on follower job performance. By contrast, follower EI demonstrated both direct and indirect effects on follower well-being. We found a dyadic measure of LMX to be a stronger predictor of follower job performance, well-being, and turnover intention than a follower only measure. Our results suggest that significant relationships between leader and follower trait EI and LMX depend on whether follower or dyadic measures of LMX are used. The study draws attention to the importance of emphasizing the level at which EI effects are expected to operate in LMX.

Help yourself by helping others: The joint impact of group member organizational citizenship behaviors and group cohesiveness on group member objective task performance change

This paper examines how a group member's individual‐targeted citizenship behavior (OCBI) and organization‐targeted citizenship behavior (OCBO) interact with a salient group‐level contextual variable, group cohesiveness, to foster positive change for that group member, starting with job self‐efficacy change, and followed by objective task performance change. Over a span of 6 months, we engaged in multilevel, multisource, multistage data collection and surveyed 587 members in 83 work groups. Our results indicate that a group member's OCBI, in comparison with OCBO, is more positively related to his or her job self‐efficacy change. Group cohesiveness was found to attenuate the relationship between a group member's OCBI and job self‐efficacy change, and conversely, to accentuate the relationship between a group member's OCBO and job self‐efficacy change. Furthermore, a group member's job self‐efficacy change mediated the interactive effects of the group member's OCBI and group cohesiveness (as well as the group member's OCBO and group cohesiveness) on his or her objective task performance change.     

Job definition discrepancy between supervisors and subordinates: The antecedent role of LMX and outcomes

This study proposed that leader–member exchange (LMX) might encourage an employee to define job breadth close to or beyond the level of his/her supervisor's expectation (enlargement effect), while simultaneously fostering a reduction in supervisor–subordinate definition discrepancy on job content (congruence effect). Using data from 184 subordinate–supervisor dyads in Taiwan, we examined the relationships among LMX, job definition discrepancy, in‐role/extra‐role behaviour, and performance rating. Results showed that LMX was positively related to employee relative job breadth and the supervisor–subordinate congruence on job content, supporting the existence of enlargement effect and congruence effect. Additionally, employee relative job breadth was positively related to extra‐role behaviour and the congruence on job content was positively related to in‐role behaviour. However, neither in‐role nor extra‐role behaviour was related to performance rating. Theoretical and practical implications are discussed.     

Leader–Member Exchange (LMX) and Performance: A Meta‐Analytic Review

This paper reports a meta‐analysis that examines the relationship between leader–member exchange (LMX) relationship quality and a multidimensional model of work performance (task, citizenship, and counterproductive performance). The results show a positive relationship between LMX and task performance (146 samples, ρ = .30) as well as citizenship performance (97 samples, ρ = .34), and negatively with counterproductive performance (19 samples, ρ = ?.24). Of note, there was a positive relationship between LMX and objective task performance (20 samples, ρ = .24). Trust, motivation, empowerment, and job satisfaction mediated the relationship between LMX and task and citizenship performance with trust in the leader having the largest effect. There was no difference due to LMX measurement instrument (e.g., LMX7, LMX‐MDM). Overall, the relationship between LMX and performance was weaker when (a) measures were obtained from a different source or method and (b) LMX was measured by the follower than the leader (with common source‐ and method‐biased effects stronger for leader‐rated LMX quality). Finally, there was evidence for LMX leading to task performance but not for reverse or reciprocal directions of effects.     

Teacher organizational citizenship behaviours and job efficacy: Implications for student quality of school life

The present study investigated the impact of teachers' organizational citizenship behaviours (OCBs) on student quality of school life (SQSL) via the indirect effect of job efficacy. A measure of teacher OCBs was developed, tapping one dimension of individual‐focused OCB (OCBI – student‐directed behaviour) and two dimensions of organization‐focused OCB (OCBO – civic virtue and professional development). In line with previous research suggesting that OCBs may enhance job efficacy, as well as studies demonstrating the positive effects of teacher efficacy on student outcomes, we expected an indirect relationship between teachers OCBs and SQSL via teachers' job efficacy. Hypotheses were tested in a multi‐level design in which 170 teachers and their students (N=3,057) completed questionnaires. A significant proportion of variance in SQSL was attributable to classroom factors. Analyses revealed that the civic virtue and professional development behaviours of teachers were positively related to their job efficacy. The job efficacy of teachers also had a positive impact on all five indicators of SQSL. In regards to professional development, job efficacy acted as an indirect variable in the prediction of four student outcomes (i.e., general satisfaction, student–teacher relations, achievement, and opportunity) and fully mediated the direct negative effect on psychological distress.     

HOW LEADER–MEMBER EXCHANGE INFLUENCES EFFECTIVE WORK BEHAVIORS: SOCIAL EXCHANGE AND INTERNAL–EXTERNAL EFFICACY PERSPECTIVES

In this article, we propose and test an integrative theory of leader–member exchange (LMX) that extends our understanding of the mechanisms affecting LMX and important organizational outcomes. We argue that LMX enhances job performance and organizational citizenship behaviors (OCBs) through 2 sets of processes. As a result of a social exchange process, high LMX managers encourage reciprocal obligations. These obligations are manifested as subordinate commitment to their supervisors. This commitment, in turn, prompts more OCBs and higher job performance. Through a second process, high LMX supervisors enhance their subordinates’ self‐efficacy and means efficacy, thereby improving job performance. Results of a field study support our predictions. Theoretical and practical implications and directions for future research are discussed.     

Understanding The Curvilinear Relationships between LMX Differentiation and Team Coordination and Performance

The leader–member exchange (LMX) literature argues that leaders develop different quality dyadic relationships with members in the same team (i.e., LMX differentiation). Research has generally not found support for a linear (i.e., main effect) relationship between LMX differentiation and team performance; rather, moderators typically determine whether the relationship is significantly positive or negative. Examining linear effect moderators alone, however, does not account for (a) potential curvilinear (i.e., inverted U‐shaped) effects, (b) explanatory mechanisms of how LMX differentiation influences team performance, or (c) moderators of curvilinear effects. Integrating social identity theory with LMX differentiation research, we propose inverted U‐shaped relationships between LMX differentiation and both team coordination (as a mediator) and team performance (as an outcome), and we examine both team size and team power distance orientation as moderators. Using data from 928 employees in 145 teams in 3 organizations, we found an inverted U‐shaped relationship between LMX differentiation and team coordination, which, in turn, partially mediated LMX differentiation's inverted U‐shaped relationship with team performance. Larger teams, or those with higher team power distance orientation, benefit more from LMX differentiation. By integrating social identity theory with LMX differentiation research, we enhance the understanding of the processes by, and conditions under, which LMX differentiation affects team performance both positively and negatively.     

Supervisors' upward exchange relationships and subordinate outcomes: testing the multilevel mediation role of empowerment

This study empirically examined the proposition that supervisors' exchange relationships with their own supervisors (i.e., leader-leader exchange, or LLX) are related to their subordinates' work-related outcomes through 3 mechanisms: (a) leaders modeling their LLX to develop and maintain their exchange relationships with their subordinates (i.e., leader-member exchange, or LMX), (b) motivating the team and its members, captured by team and individual empowerment, and (c) facilitating the relationships between LMX and individual outcomes. Analyses of multisource and lagged data from 104 team supervisors and 577 subordinates showed that LMX mediated the positive relationship of LLX on subordinates' individual empowerment. Furthermore, team empowerment and individual empowerment sequentially mediated the positive relationships between LLX and subordinates' job satisfaction and job performance. The authors also found that the indirect relationships of LMX with job satisfaction and job performance via individual empowerment were stronger when LLX was higher. Theoretical and practical implications of these findings are discussed.     

Collective‐efficacy as a mediator of the relationship of leaders' personality traits and team performance: A cross‐level analysis

The relationship between a leader's personality and his team's performance has been established in organisational research, but the underlying process and mechanism responsible for this effect have not been fully explored. Both the traditional multiple linear regression and the multilevel structural equation model approaches were used in this study to test a proposed mediating model of subordinates' perception of collective efficacy between leader personality and team performance. The results show that the team leader's extraversion and conscientiousness personality traits were related positively to both the team‐average (individual) perception of collective efficacy and team performance, and the collective efficacy mediated the relationship of the leader's personality traits and team performance. This study also discusses how Chinese cultural elements play a role in such a mediating model.     

Reciprocal Relationships between Leader–Member Exchange (LMX) and Job Satisfaction: A Cross‐Lagged Analysis

While previous research has mainly emphasised the importance of leader–member exchange (LMX) to job satisfaction, there is a lack of research on reciprocal relationships between job satisfaction and LMX. In this study, we not only suggest that good LMX increases job satisfaction, but that job satisfaction can also enhance high‐quality supervisor–employee relationships. A full cross‐lagged panel analysis was used to test reciprocal relationships between LMX and job satisfaction. Employees (N= 279) of a large information technology company filled out questionnaires at two times, with a time lag of 3 months. In line with our predictions, findings revealed a positive relationship between LMX and job satisfaction both at Time 1 and Time 2. Moreover, LMX at Time 1 predicted the increase of job satisfaction at Time 2, and job satisfaction at Time 1 predicted the increase of LMX at Time 2. The results demonstrate the need to consider reciprocal relationships between job satisfaction and LMX when explaining employees' workplace outcomes. Our findings are discussed in terms of positive psychology theory.     

THE ROLE OF JOB EMBEDDEDNESS ON EMPLOYEE PERFORMANCE: THE INTERACTIVE EFFECTS WITH LEADER–MEMBER EXCHANGE AND ORGANIZATION‐BASED SELF‐ESTEEM

Although job embeddedness was originally conceptualized to explain job stability or “why people stay” in their organizations, this investigation examines the role of job embeddedness as a hypothesized moderator of relationships among leader–member exchange (LMX), organization‐based self‐esteem (OBSE), organizational citizenship behaviors (OCBs), and task performance. Findings from 2 studies involving 367 employees and 41 supervisors, 1 in a telecommunications company and another in a manufacturing setting, support hypotheses concerning job embeddedness as a moderator of the relationship between (a) LMX and task performance within a telecommunication sample and LMX and OCBs in a sample of manufacturing employees, and (b) OBSE and OCBs in a manufacturing sample. Further, a hypothesized 3‐way interaction involving job embeddedness, LMX, and OBSE on task performance was found in a sample of manufacturing employees. The implications of these findings for studying and managing job embeddedness in relation to employee performance are discussed.     

Re-examining Citizenship: How the Control of Measurement Artifacts Affects Observed Relationships of Organizational Citizenship Behavior and Organizational Variables

We examined the impact that measurement artifacts (antithetical items that overlap counterproductive work behavior (CWB), agreement response, halo in supervisor ratings) in organizational citizenship behavior (OCB) measures has on observed relationships between OCB and 15 predictors. Respondents were 146 employees and their supervisors who completed surveys that included OCB measures with and without artifacts. Predictors (conscientiousness, emotional stability, empathy, distributive justice, procedural justice, role ambiguity, role conflict, leader–member exchange, affective organizational commitment, job satisfaction, negative and positive emotion, turnover intention, CWB, and task performance) were chosen that related to OCB in prior meta-analyses. Results with the OCB scale with artifacts were consistent with meta-analyses, whereas results with the artifact-controlled OCB scale were not, suggesting that accepted conclusions about OCB’s relationships with many other variables should be reexamined.     

The effects of transformational leadership behaviours on follower outcomes: An identity-based analysis

The aim of this study was to explore two of the mechanisms by which transformational leaders have a positive influence on followers. It examined the mediating role of follower's leader and group identification on the associations among different transformational leader behaviours and follower job satisfaction and supervisor-rated job performance. One hundred and seventy-nine healthcare employees and 44 supervisors participated in the study. The results from multilevel structural equation modelling provided results that partially supported the predicted model. Identification with the leader significantly mediated the positive associations between supportive leadership, intellectual stimulation, personal recognition, in the prediction of job satisfaction and job performance. Leader identification also mediated the relationship between supportive leadership, intellectual stimulation, personal recognition, and group identification. However, group identification did not mediate the associations between vision leadership and inspirational communication, in the prediction of job satisfaction and job performance. The results highlight the role of individualized forms of leadership and leader identification in enhancing follower outcomes.     

Revisiting the mediating role of leader–member exchange in transformational leadership: the differential impact model

Transformational leadership (TFL) has been proposed as an essential antecedent of leader–member exchange (LMX), which in turn affects outcomes in organizations. We extend this mediation hypothesis in two ways by proposing a differential impact model, which we test on three organizational outcomes: employee job satisfaction, employee organizational commitment, and leader effectiveness. First, we extend LMX’s mediational impact—which has previously only been tested for employee outcomes—to leader effectiveness. Second, we argue that this mediation will be stronger for outcomes that are more proximal rather than distal to dyadic relations between leader and followers (high proximity: job satisfaction; medium proximity: organizational commitment; low proximity: leader effectiveness). Meta-analytic structural equation modelling based on 132 studies revealed that LMX mediates TFL’s relationships with employee outcomes (more strongly for job satisfaction than for commitment), but not with leader effectiveness, whereas TFL showed a stronger direct link to leader effectiveness. The findings suggest that TLF and LMX contribute differentially to organizational outcomes depending on their proximity to dyadic relations between leaders and followers. The differential impact model uncovers leadership effectiveness processes, integrates influential leadership theories, and highlights the importance of distinguishing between different outcome measures and the processes facilitating them.     

How leaders stimulate employee learning: A leader–member exchange approach

This study investigated how leader–member exchange (LMX), goal setting, and feedback are related to employee engagement in learning activities. Two different mechanisms were proposed: a mediating mechanism holding that LMX elicits specific leader behaviours (i.e., goal setting and feedback) which would mediate the LMX‐learning relationship, and a moderating mechanism, holding that LMX would strengthen the effect of these leader behaviours. A sample of 1,112 employees from 7 organizations completed questionnaires that measured LMX, goal specificity, feedback, and self‐reports of employee engagement in learning activities. The 233 direct leaders of these employees completed questionnaires that measured goal difficulty and leader ratings of employee engagement in learning activities. Multi‐level analysis showed that goal difficulty and goal specificity mediated the relationship between LMX and employee engagement in learning activities, and that LMX moderated the relationship of goal difficulty with employee engagement in learning activities. With these findings, the present study contributes to the literatures on LMX, goal setting, and employee development.
