Servant Leadership: A systematic review and call for future research

Notwithstanding the proliferation of servant leadership studies with over 100 articles published in the last four years alone, a lack of coherence and clarity around the construct has impeded its theory development. We provide an integrative and comprehensive review of the 285 articles on servant leadership spanning 20?years (1998–2018), and in so doing extend the field in four different ways. First, we provide a conceptual clarity of servant leadership vis-à-vis other value-based leadership approaches and offer a new definition of servant leadership. Second, we evaluate 16 existing measures of servant leadership in light of their respective rigor of scale construction and validation. Third, we map the theoretical and nomological network of servant leadership in relation to its antecedents, outcomes, moderators, mediators. We finally conclude by presenting a detailed future research agenda to bring the field forward encompassing both theoretical and empirical advancement. All in all, our review paints a holistic picture of where the literature has been and where it should go into the future.

How and When Servant Leaders Enable Collective Thriving: The Role of Team–Member Exchange and Political Climate

Thriving teams are critical to the effective functioning of an organization. Extending Spreitzer et al.’s (2005) socially embedded model of thriving at work to the team level, this study explores how and when servant leadership promotes collective thriving. Through data collected from 80 teams composed of 520 employees, the study reveals that servant leaders help embed members in high‐quality team–member exchange relationships, which in turn enables their collective thriving. The authors find that a highly political climate is a dual‐stage moderator hindering the positive impact of servant leadership on collective thriving. The findings move forward extant servant leadership and thriving literature. The authors also offer practical implications for how organizations can nurture and reap benefits from thriving teams and the active role of employees in this process.     

Servant leadership,employer brand perception,trust in leaders and turnover intentions: a sequential mediation model

The study aimed to examine the impact of the servant leadership style on employee turnover intentions by investigating the sequential mediating effects of employer brand perception and level of trust subordinates have in their leaders. Results of the study were obtained by analysing data collected from 253 employees working in Indian organizations. The results fully support the hypotheses proposed in the study, illustrating that perceived servant leadership style is negatively associated with employee turnover intentions. Further, servant leadership-turnover intentions relationship is sequentially mediated by employer brand perception and the level of trust subordinates have in their leaders. The study also found that only the servant leadership style followed by leaders was not enough to directly influence the level of trust employees placed in their leaders. A positive and strong employer brand perception emerged as an important mechanism that helped servant leaders gain the trust of their followers. The theoretical and managerial implications are further discussed in the light of these findings.

The servant identity: Influences on the cognition and behavior of servant leaders

This paper approaches the study of servant leadership by concentrating on the identity of servant leaders. An identity is important to one's sense of self and it influences the way a leader cognitively processes socially relevant information and exercises a particular leadership behavior in response to a situation. Unlike existing studies, which typically approach servant leadership as one of a number of possible leadership styles, and which merely describe its characteristics, this paper serves to explain the basis for individuals enacting this mode of leadership. This paper defines and elaborates on the servant identity by showing the psychological factors constituting it. Taking a socio-cognitive approach, the paper offers a theoretical framework for the servant identity. The framework encompasses the cognitive and behavioral disposition of leaders with servant identity and the organizational contexts that influence it. This new angle on servant leadership opens avenues for future research and practice.     

Servant leaders inspire servant followers: Antecedents and outcomes for employees and the organization

Despite widespread adoption of servant leadership, we are only beginning to understand its true utility across multiple organizational levels. Our purpose was to test the relationship between personality, servant leadership, and critical follower and organizational outcomes. Using a social influence framework, we proposed that leader agreeableness and extraversion affect follower perceptions of servant leadership. In turn, servant leaders ignite a cycle of service by role-modeling servant behavior that is then mirrored through coworker helping behavior and high-quality customer service, as well as reciprocated through decreased withdrawal. Using a multilevel, multi-source model, we surveyed 224 stores of a U.S. retail organization, including 425 followers, 110 store managers, and 40 regional managers. Leader agreeableness was positively and extraversion was negatively related to servant leadership, which was associated with decreased follower turnover intentions and disengagement. At the group-level, service climate mediated the effects of servant leadership on follower turnover intentions, helping and sales behavior.     

Country differences in the relationship between leadership and employee engagement: A meta-analysis

Leadership is frequently related to important organizational outcomes such as follower engagement. However, to date we have little insight into the degree to which this relation is contingent upon (a) types of leadership style and (b) national culture. These two issues are addressed in a meta-analysis of 209 independent (257 effect sizes), mainly cross-sectional studies (79%), involving 82,386 participants from 45 countries. The findings show that whereas abusive supervision was negatively associated with work engagement, several leadership styles (e.g., servant, empowering, ethical, and charismatic leadership) have positive correlations with subordinate engagement; some dimensions of national culture (e.g., gender egalitarianism, human orientation, performance orientation, future orientation, and power distance) moderate the leadership–employee engagement relationship. However, the correlations between servant, ethical, and transactional leadership and subordinate engagement are less likely to vary across national cultural characteristics. Notwithstanding the proliferation of leadership–employee engagement literature with more than 200 published articles, a strong reliance on cross-sectional designs have impeded it to gain any solid conclusions about causality due to endogeneity biases. We conclude by providing a detailed future research agenda and discussing how our results can stimulate future leadership research and inform practices with regards to leader development.     

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.     

Assessing global leadership competencies: the critical role of assessment centre methodology

The purpose of this conceptual paper is to examine the use of assessment centre (AC) methodology for addressing the ever-increasing demand for effective talent management of global leaders. Research is reviewed on the most commonly used questionnaire tools for assessing global leadership competencies, which lack the AC’s ability to provide behavioural evidence of leadership competency. A literature search is conducted to identify the extent to which scholarly research to date has examined the use of ACs to measure global leadership competencies. Based on the findings from the review of the literature, the authors recommend further exploration of a leadership AC approach as a ‘best practice’ talent management tool for measuring global leadership competencies. A framework is provided for designing ACs to evaluate and provide developmental feedback on the competencies identified as critical for successful leadership performance in an organization’s global environment.     

Servant leadership

As corporations are eagerly pursuing reengineering and reorganization, leadership functions are changing to champion these efforts. Traditionally, organizations have had a "top-down" management approach, however, there is a gradual shift to other leadership models. Servant leadership is being successfully implemented in many settings. Servant leadership, first popularized by Robert Greenleaf in 1970, puts serving others as the number one priority. Ten characteristics of a servant leader include: Listening, empathy, healing, awareness, persuasion, conceptualization, foresight, stewardship, commitment to the growth of people, and building community. Both servant leadership and the chaos theory have in common the central tenet of relationships. Since America is now approximately 80 percent a "service-economy," servant leadership can greatly benefit the individual employees, as well as help to facilitate the organization's pursuit of its changing strategic plans.     

Same difference? Exploring the differential mechanisms linking servant leadership and transformational leadership to follower outcomes

This paper aimed to provide insights into the different mediating mechanisms through which servant leadership (SL) and transformational leadership (TFL) affect followers. We also investigated environmental uncertainty as a moderator of the effects of servant leadership and transformational leadership. Based on the results of two experimental studies and one field study, we concluded that both SL and TFL were related to organizational commitment and work engagement; however, the manner in which they exerted their influence differed. SL worked primarily through follower need satisfaction, whereas TFL worked mainly through perceived leadership effectiveness. The moderating influence of uncertainty was inconsistent across the studies.     

Blazing new trails or opportunity lost? Evaluating research at the intersection of leadership and entrepreneurship

More than a decade ago, scholars formally conceptualized the potential synergy between leadership and entrepreneurship scholarship. Our work highlights research accomplishments occurring at the interface of these two intellectual areas as well as identifying untapped possibilities for continued research. We highlight how recent efforts have witnessed a mutual exchange of ideas that present opportunities benefiting both fields. Drawing from four key domains of entrepreneurship previously proposed to mutually inform future leadership research efforts, we make suggestions for integrating entrepreneurial opportunities, the roles of individual and entrepreneurial teams, the modes of organizing entrepreneurial ventures, and differing entrepreneurial environments with key trends important to leadership research, such as servant leadership and leader-member exchange theory. Overall, our work provides an assessment of the state of the art surrounding the coalescence of leadership and entrepreneurship research and sets an agenda for the next decade of research at this intersection.     

Measuring exposure to bullying and harassment at work: Validity,factor structure and psychometric properties of the Negative Acts Questionnaire-Revised

Abstract

This study investigates the psychometric properties, factor structure and validity of the revised Negative Acts Questionnaire-Revised (NAQ-R), an instrument designed to measure exposure to bullying in the workplace. By reanalyzing data based on a heterogeneous sample of 5288 UK employees, the results show that the 22-item instrument has a high internal stability, with three underlying factors: personal bullying, work-related bullying and physically intimidating forms of bullying, although the instrument may also be used as a single factor measure. Criterion validity was explored by relating the scores on the NAQ-R to a single-item measure of perceived victimization from bullying, showing high correlations with both the total NAQ-R and scores on the three factors. Targets of bullying scored significantly higher on all 22 items compared to non-targets. The NAQ-R correlated as expected with measures of mental health, psychosocial work environment and leadership, indicating a good construct validity of the instrument. Furthermore, a latent class cluster (LCC) analysis showed that the instrument may be used to differentiate between groups of employees with different levels of exposure to bullying, ranging from infrequent exposure to incivility at work to severe victimization from bullying and harassment. The more commonly used operational criteria can also be used to detect targets of bullying. Hence, the NAQ-R is proposed as a standardized and valid instrument for the measurement of workplace bullying.     

Reviewing Leadership Styles: Overlaps and the Need for a New ‘Full‐Range’ Theory

A central topic in leadership research concerns the impact of leadership style – the pattern of attitudes that leaders hold and behaviors they exhibit. Since the year 2000, several new leadership styles have been proposed to capture important missing aspects beyond the dominant charismatic/transformational and transactional framework. The authors review the emerging literature on these new styles – ideological leadership, pragmatic leadership, authentic leadership, ethical leadership, spiritual leadership, distributed leadership, and integrative public leadership – as well as the recent work on servant leadership. They also comment on the Ohio State studies on leadership, and then discuss the ways in which these many styles overlap with transformational leadership and each other, and issue a call to leadership researchers to collectively develop a new ‘full‐range’ model of leadership that encompasses and distills what is unique about these various styles. The authors argue that such an integrated full‐range model is necessary for research on leadership style to progress.     

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.     

The Authentic Leadership Inventory (ALI): Development and empirical tests

This paper presents the development and preliminary validation of a new measure of authentic leadership, the Authentic Leadership Inventory (ALI). It also assesses the recently developed Authentic Leadership Questionnaire (ALQ). Results indicate some concerns with the ALQ but support the content validity, reliability, factor structure, convergent and discriminant validity, concurrent validity, and freedom from impression management response bias of the ALI. Confirmatory factor analyses also do not support treating authentic or transformational leadership as universally global constructs. Instead, it is argued that future research would better be served by using separate authentic and transformational dimensions (rather than aggregate or global measures) to understand the unique aspects of both leadership constructs.     

Moderating role of subordinates' attitudes on transformational leadership and effectiveness: A multi-cultural and multi-level perspective

We conducted the current multi-cultural, multi-level study with three objectives in mind. First, we examined the association of transformational leadership and leader effectiveness across two different cultures, the United States (U.S.) and Korea, with three followers' attitudes toward their leader (trust in the leader, loyalty, and value congruence) as moderators of this association. Second, we conceptualized followers' collectivistic orientation as a personal value, regardless of their nationality, and tested its moderating effect on the leadership–effectiveness association. Finally, we employed a multi-level approach throughout to examine whether transformational leadership processes, and in contrast individualized leadership, operated at different levels of analysis across different countries. Results from WABA and regression analyses indicated that transformational leadership operated at the individual level of analysis in both samples and was effective across different cultures. Specifically, followers' attitudes served as moderators of the transformational leadership–effectiveness association only in the U.S. sample, while collectivistic orientation had a significant moderating effect in both samples. Results from WABA also indicated that individualized leadership operated at the dyadic level for the U.S. sample and at the individual level for the Korean sample. Several theoretical and practical implications of the results are discussed.     

Economic assumptions and economic context: Implications for the study of leadership

Separated by longstanding differences, mainstream leadership scholarship and economics have rarely conversed. In this paper, we contribute to the emerging conversation between the two fields by (1) summarizing how economic assumptions about leadership may broadly inform leadership scholarship, and (2) offering a framework for conceptualizing the economic context in which leaders operate. We argue that inclusion of economic context in models of leadership antecedents, processes and outcomes is likely to offer rich insights for leadership selection, behavior, performance outcomes, and evaluation. We review recent studies that integrate economics and leadership and further consider how economic approaches both inform and refine current areas of interest to leadership scholars (e.g., shared leadership and values-based ethical, servant, and authentic approaches) and point to new pathways of focus in mainstream leadership (e.g., leader discretion).     

An integrative framework for global leadership competency: levels and dimensions

As developing excellent global leaders should be an urgent priority of companies in the global business world, there has been considerable research in this area. Despite this, there is limited research on the systematic global leadership competency structure reflecting both on its levels and dimensions and on specific competencies. The purpose of this article is to create a theory-based integrative framework that can be used to identify the competencies comprising global leadership. To accomplish this purpose, an integrative literature review was employed on competency theory and global leadership, resulting in the development of an integrative framework for global leadership competency. The framework, with three levels and four dimensions, established in this article contributes to corporations in providing a means of developing company-specific models of global leadership competency. Also discussed are implications for future human resource development research and theory building.
