Construct validation in leadership research: Explication and illustration

The field of leadership typically employs constructs—variables that cannot be directly measured—in its research. Yet, our measures are rarely subjected to systematic assessment of their construct validity. This paper presents arguments about the importance of the construct validation process and illustrates why such concerns are well founded by examining the most commonly used measure of subordinate-perceived leader–member exchange, the LMX-7 scale. Using bakery workers (N = 379) and employed MBA students (N = 350), discriminant validity was investigated by exploratory factor analysis in the first sample, confirmatory factor analysis in the second sample, and correlation and multiple regression analysis in a subset of the second sample (N = 220). The results suggested poor subordinate LMX-7 discriminant validity and that subordinate LMX-7 scores were substantially predicted by measures of supportive leadership and supervisor satisfaction (R² = .71). Implications for future LMX theory and research are discussed as well as the types of construct validity evidence that we need to gather on our research instruments before and while they are employed in substantive studies of leadership phenomena.     

Abusive supervisory reactions to coworker relationship conflict

This study extends research on abusive supervision by exploring how supervisor reports of conflict with their coworkers are related to abusive behaviors and resulting outcomes. We utilize research on displaced aggression, conflict, and leader–member exchange (LMX) theory to formulate our hypotheses. Results from two samples of 121 and 134 matched supervisor–subordinate dyads support the idea that supervisors experiencing coworker relationship conflict are likely to engage in abusive behaviors directed toward their subordinates and that LMX quality moderates this relationship. Additionally, abusive supervision was associated with decreased work effort and organizational citizenship behaviors (OCB). Results also indicate that in both samples abusive supervision mediates the relationships between supervisor reports of coworker relationship conflict and OCB, and in one sample mediates the association between supervisor-reported coworker relationship conflict and work effort.     

Leader-member exchange and organizational citizenship behaviors: Contextual effects of leader power distance and group task interdependence

In this paper we explore the context of the relationship between leader-member exchange and organizational citizenship behaviors (OCB). We maintain that workgroup leader's power distance and the extent of task interdependence in the group exert cross-level effects on the LMX-OCB relationship. We assert that leader power distance attenuates the relationship between LMX and OCB, and this effect is stronger in workgroups with high degree of task interdependence. Results of hierarchical linear modeling analysis of data gathered from 245 employees nested in 54 workgroups supported our hypotheses. LMX-OCB relationship was weaker in workgroups led by high power distance leaders. Further, the three-way cross-level interaction between LMX, leader power distance and group task interdependence demonstrated that the tendency for LMX to have a stronger positive effect on OCB when leader power distance was low rather than high was more pronounced in high task interdependence teams.     

LMX differentiation: A multilevel review and examination of its antecedents and outcomes

We examine antecedents and outcomes of leader–member exchange (LMX) differentiation, or the variability in LMX patterns within work groups. Individual-level characteristics and behaviors of leaders and followers, group context, and organizational context variables are presented as antecedents. We review and offer theoretical extensions to research examining the outcomes of LMX differentiation at the individual, group, and organizational levels. Our aim is to contribute to a meso-model of leadership and stimulate research that attends to the core element of the LMX model–LMX differentiation.     

Differentiated transformational leadership and knowledge sharing: A cross-level investigation

Building on theories of differentiated leadership and knowledge sharing, this study investigated the influence of dual-level transformational leadership on three group climates, leader–member exchange (LMX), and knowledge sharing. Using data from 275 employees of 71 work groups in five companies, we found that group-focused leadership and individual-focused leadership both facilitated knowledge sharing while the three group climates and LMX acted as mediators at the group level and individual level, respectively. In addition, our analysis showed an interesting finding in Chinese organizations: an innovativeness climate and a fairness climate contributed to an affiliation climate, which in turn promoted knowledge sharing.     

Leader negative feedback-seeking and leader effectiveness in leader-subordinate relationships: The paradoxical role of subordinate expertise

From a motivational perspective of feedback-seeking behavior, we examined the mediating role of leaders' negative feedback-seeking from subordinates in the relationship between the quality of leader-member exchange (LMX) and subordinates' evaluation of leader effectiveness, along with the moderating role of subordinate expertise in the mediated relationship. Using 151 unique matched sets of leader and subordinate reports obtained from 5 large Korean companies, we found that the positive relationship between LMX and leader effectiveness was mediated by leaders' negative feedback-seeking. Additionally, the positive relationship between LMX and leader negative feedback-seeking was stronger when perceived subordinate expertise was lower. Lastly, the indirect effect of LMX on leader effectiveness through leader negative feedback-seeking was stronger when perceived subordinate expertise was lower. These findings were obtained after controlling for leaders' power distance and goal orientations that might influence their motives to seek or avoid feedback. Theoretical and practical implications are discussed.     

Leader-member exchange as a linking pin in the idiosyncratic deals - Performance relationship in workgroups

In the current investigation, idiosyncratic deals (i-deals; individualized work arrangements) are modeled as differentiated resources that shape leader-member exchange (LMX) relationships in workgroups. We integrate literature on leader-member exchange (LMX) with research on i-deals to argue that employee evaluations of i-deals received from the grantor –typically the leader- enhance employee perceptions of LMX, which in turn become instrumental in generating positive performance outcomes. Furthermore, because workgroup characteristics have potential implications on the relationship between a deal grantor and the deal recipient, drawing upon social identity theory of leadership, we reason that the i-deals-LMX relationship is affected by the overall value congruence among the group members. Cross-level moderated mediation analyses on multi source data obtained from 289 employees nested in 60 workgroups showed that the mediational role of LMX in the i-deals to performance outcomes relationship was weaker in high value congruence groups.     

Daily perceptions of relationship quality with leaders: implications for follower well-being

ABSTRACT

We examined how a key relationship at work, an employee’s relationship with their leader, affects employee daily well-being. In a study of 129 employees across a variety of industries, we examined how follower perceptions of their daily leader–member exchange (LMX) quality across a workweek influenced their well-being (n?=?468 observations). Results provided general support for our hypotheses. Specifically, we found that on days when employees perceived a higher quality LMX relationship with their leader, they were more likely to report a sense of belongingness, which was then positively associated with daily reports of vigor and negatively associated with emotional exhaustion. Lagged analyses showed that perceptions of LMX quality were also negatively associated with reports of emotional exhaustion the following workday suggesting that these effects may persist over time. Finally, we found that day-to-day variation in reports of LMX quality attenuated the beneficial effects of LMX on relatedness and vigor supporting our hypothesis that uncertainty related to resource availability may contribute to a threat mindset focused on resource conservation rather than engagement. Implications and future research on leadership and employee well-being are discussed.     

Contextualizing LMX within the workgroup: The effects of LMX and justice on relationship quality and resource sharing among peers

While leader–member exchange (LMX) has evolved, a richer understanding continues to evade scholars due to the sustained focus on the leader–member dyad. We argue that LMX theory remains incomplete until contextual factors surrounding these pivotal relationships are accounted for including the impact of coworker exchange relationships, peer exchange, and perceptions of justice regarding individual LMX relationships. A fully crossed experimental design manipulating participant LMX and distributive justice and coworker LMX and distributive justice was employed to understand how these constructs affect coworker exchange relationships. Support was found for a causal model which specifies that justice moderates the causal relationship between LMX similarity and CWX, which subsequently leads to increased sharing of resources among coworkers. The data suggest that workgroup members are savvy to differences within individual leader–member relationships, where the sharing of resources among peers is determined by their own LMX, the LMX of their coworker and perceptions of justice of their respective LMX levels. These findings are contextualized in extant leadership research and practice.     

The moderating effect of political skill on the demographic dissimilarity — Leader–member exchange quality relationship

LMX theorists have long argued that similarity between supervisors and subordinates will lead to the development of higher quality leader–member exchange (LMX) relationships. However, studies that have examined the impact of similarity on these relationships have found mixed results, suggesting the need for examining moderators. The purpose of the present study was to examine the impact of subordinates' political skill on the relationship between supervisor–subordinate racial similarity/dissimilarity (RSD) and the quality of LMX relationships. The sample consisted of 189 participants in a retail service organization. The results indicate that political skill is a significant moderator, and plays a substantial role in LMX relationship quality for racially dissimilar supervisor–subordinate dyads. The strengths and limitations of the study, and directions for future research are discussed.     

A new model for examining the leader – member exchange (LMX) theory

The theory of leader?–?member exchange (LMX) is re-examined. The concepts of social and economic exchange misused in previous research are clarified. A model that describes the exchange relationships between manager and subordinates is presented. The model challenges the well-accepted positive relationship between high quality of LMXs and organizational performance in previous studies by pointing out that the relationship may lead to negative results. New research propositions based upon the model are offered to encourage further research efforts.     

Investigating the Moderating Effects of Leader–Member Exchange in the Psychological Contract Breach–Employee Performance Relationship: A Test of Two Competing Perspectives

Leader–member exchange (LMX) has been characterized as a form of social support capable of buffering the effects of negative work experiences. However, employees with high‐quality relationships with leaders in the organization may have stronger negative reactions when psychological contracts are breached. Thus, while a social support perspective would suggest that LMX minimizes the adverse impact of psychological contract breach on employee performance, a betrayal perspective proposes that high LMX would aggravate the negative effects. Using cross‐sectional and longitudinal research designs, results across three samples provided support for the betrayal perspective. That is, breach had a stronger negative relationship with organizational citizenship behaviours and in‐role performance under conditions of high LMX. Implications of these results and future research directions are discussed.     

Leader–member exchange and organizational dehumanization: The role of supervisor’s organizational embodiment

This research examined the negative relationship between leader–member exchange (LMX) and organizational dehumanization (i.e., employees’ perceptions that their organization treats them like tools), and specifically the consequences of this LMX–dehumanization relationship on employees’ emotional exhaustion, affective commitment, and voice behaviors. Further, given that supervisors act as representatives of the organization, we argued that these relationships would be stronger for employees identifying their supervisor with the organization (i.e., high supervisor’s organizational embodiment). Across two samples, results showed that high-quality LMX was negatively associated with organizational dehumanization. Further, organizational dehumanization was found to mediate the relationships between LMX and outcomes (i.e., emotional exhaustion, affective commitment, and voice behaviors). Finally, the mediation model was moderated by supervisor’s organizational embodiment. More specifically, the negative effects of LMX on organizational dehumanization and its subsequent outcomes were stronger when leaders were perceived as sharing many characteristics with their organization. This research expands the recent and scarce knowledge on the determinants, boundary conditions and outcomes of organizational dehumanization. Our findings suggest that interpersonal relationships at work and, in particular, very common supervisor-related perceptions should be considered when examining organizational dehumanization.     

Differentiated leader–member exchange,justice climate,and performance: Main and interactive effects

Leaders form different quality leader–member exchange (LMX) relationships with their subordinates. This variable treatment termed LMX differentiation can have negative effects on individuals' behavior and attitudes. In this study, we examined the cross-level main effect of justice climate on task performance and the moderating role of justice climate on the relationship between LMX differentiation and task performance. We tested these two hypotheses using a field study of 90 subordinates nested under 27 supervisors. Procedural justice climate, not distributive justice climate, was found to positively influence subordinate task performance. Further, distributive justice climate, not procedural justice climate, was found to moderate the LMX differentiation–task performance relationship; such that the relationship was positive when distributive justice climate was high and negative when distributive justice climate was low. Findings and future directions are discussed.     

Quantitative and qualitative examination of propositions concerning supervisor–subordinate convergence in descriptions of leader–member exchange (LMX) quality

Two studies were conducted to quantitatively and qualitatively examine supervisor–subordinate differences in perceptions concerning the quality of their LMX relationship. The results provided strong support for a lack of construct convergence between these two perspectives. Specifically, the findings suggest that leaders tend to focus more on task-oriented subdimensions and tend to give them greater weight when evaluating LMX relationships. However, subordinates are more oriented toward the social aspects of the relationship and perceive them as more important. This differential pattern was found to be generalizable across gender, race, and industry types.     

Effects of relational schema congruence on leader-member exchange

Drawing on social exchange processes in leader-member exchange (LMX), we posit that expressive relational schema (ERS) and instrumental relational schema (IRS), which refer to knowledge structures in social exchange processes, act as antecedents of follower-rated LMX. Specifically, we discuss how leader-follower relational schema congruence/incongruence informs follower-rated LMX. Using polynomial regression models, we analyze 205 leader-follower dyads and test the congruent/incongruent effects on follower-rated LMX. The findings show that ERS congruence has a positive effect on follower-rated LMX, while IRS congruence has a negative effect on follower-rated LMX. Results also demonstrate that ERS incongruence impairs more follower-rated LMX than does ERS congruence, and IRS incongruence and IRS congruence have the same follower-rated LMX. Implications for LMX theory and research are discussed.     

When opposites do (and do not) attract: Interplay of leader and follower self-identities and its consequences for leader–member exchange

Employees' self-identities, or the ways in which they define themselves relative to others, have implications for the quality of leader and follower relationships at work. Although self-identity has been examined within the context of transformational and charismatic leadership, its relevance for leader–member exchange (LMX) has received little attention. In this study we integrate LMX and self-identity theories. Doing so proved useful because it was found that leader and follower identities predicted LMX quality, as did the fit between leader and follower identities and interactions among fit at different self-identity levels. LMX quality fully mediated relationships of self-identity fit with job performance, regardless of whether LMX was reported by subordinates or their supervisors. Lastly, we also found that self-identity predicted LMX agreement across supervisors and subordinates. Implications of our findings for theory and practice are discussed.     

Leader–member exchange,shared values,and performance: Agreement and levels of analysis do matter

In this study, we first investigate the levels of analysis at which leader–member exchange (LMX) operates; second, we examine the nature of the LMX–performance relationship when a superior and a subordinate agree as compared to disagree concerning the quality of their exchange; third, we test the effect of superior–subordinate agreement about work values on the LMX–performance relationship; and fourth, we simultaneously consider the effects of LMX agreement–disagreement and values agreement–disagreement on the LMX–performance relationship. Our findings indicate that LMX operates primarily at the independent dyad level of analysis. We also found that LMX and performance are most strongly related and display the strongest dyadic-level effects when superior and subordinate assessments of LMX and values are in agreement.     

Complementary person-supervisor fit: An investigation of supplies-values (S-V) fit,leader-member exchange (LMX) and work outcomes

By applying the supplies-values (S-V) fit approach from the complementary person-environment (P-E) fit literature to the leader-employee perspective, and drawing upon social exchange theory, we examine how fulfillment of different work values is related to Leader-Member Exchange (LMX) and work outcomes. First, polynomial regression analyses combined with response surface analysis of data collected at two time points (N = 316) showed that LMX (Time 2) was higher the more the leader fulfills the employee's work values (Time 1). Second, LMX (Time 2) was higher when leader supplies (Time 1) and employee work values (Time 1) were both high than when both were low. Third, analyses of data from a sub-sample of matched leader-employee dyads (N = 140), showed that LMX (Time 2) played a mediating role on the relation between S-V fit (Time 1) and work outcomes (Time 2). Specifically, we found eight out of 10 relationships between S-V fit (Time 1) and leader-rated task performance and OCB (Time 2) to be fully mediated by LMX (Time 2). LMX (Time 2) partially mediated the relation between S-V fit (Time 1) and job satisfaction (Time 2) as only two out of five relationships were fully mediated.
