Abstract: We developed and testified a theoretical model
which explained how transformational mentorship style
influences individual creativity and job satisfaction in the
context of educational research teams in the context of
educational research teams. Our sample included 81
teams consisting of 258 graduate students from the
mainland China. The dyadic data indicated that the LMX
fully mediated the relationship between transformational
leadership and job satisfaction and the intrinsic
motivation fully mediated the relationship between
transformational leadership and creativity. The results of
this present study extended the transformational
leadership theory in the educational research settings,
and shed the light on the mechanism how leadership
style behavior would influence the member’s creativity.
Furthermore, the study had the practical implication for
education management and research management
concerning about how to create the contextual
environment in order to facilitate the members’
individual creativity.

Introduction
The research team is becoming basic unit for
knowledge creation and technology innovation.
Specifically, in educational research team which consists
of mentor and graduate students, besides the goals of
complementing research projects,fostering the potential
young scientists is its primary goal. Therefore, the
relationship between mentor and the graduate students is
a critical kind of interpersonal relationships like leadermember relationship in general teams in organization. In
the same way, the behavior style of mentors will have
great impact on the graduate performance like that of
leaders on team member in other teams. However,
although educational research team is becoming main
force in implementing scientific innovation and
knowledge creation in China, there are few studies to
examine how the mentors’ mentorship style would affect
the performance, especially creative performance of
graduate students. Therefore, to examine the mechanism
of mentorship on mentee’s creative performance would
not only make a new contribute to leadership theory by
testifying the leadership style in the context of
educational research teams, but also deepen the
understanding of how to improve the graduate students’
creativity via the vehicle of the mentorship.
This paper aims to examine how the
transformational mentorship in an educational research
team, affect the creative performance of mentees. Since
the role of the mentors in the educational research team
is quite similar to that of the leaders of general teams in
many ways, and the graduate students/mentees to the
followers. We applied the full range leadership theory to
describe the mentorship style in this study. The full
range leadership style depicts the leadership from lazzi
faire style to transactional and transformational style.
And many empirical studies demonstrate the evidence
that transformational leadership style would positively
affect the follower’s creativity. Therefore, in this study,
we focused on examining how the transformational
mentorship influences the mentee’s creativity in
educational research team.
The paper is organized as follows: the second section
is the literature review of leadership theory, LMX,
intrinsic motivation and individual performance in the
educational research teams and proposal of the
hypotheses; the third section is the methodology, in
which the sample, data collection and measurement are
indicated; the results of the analysis will be presented
next; and the final section is the conclusion and
discussion.

Literature review
2.1Transformational leadership
Leadership is a strategic factor to influence the
individual performance and organizational performance
in various organization settings. It is defined as a process
that includes influencing the task objectives and
strategies of a group or organization, influencing people
in the organization to implement the strategies and
achieve the objectives, influencing group maintenance
and identification, and influencing the culture of the
organization. There are affluent researches from
different perspectives to study leadership.
Leadership styles have been defined as those
behaviors exhibited by leaders which can be measured or
compared [1]. Leadership styles have also been explained
as the processes through which decisions are made
within an organization [2]. Leadership styles may vary
widely along the spectrum of leadership [3]. Different
leadership styles encourage different types of responses
from followers, affecting their productivity, motivation,
and morale, depending upon the context of the
organization.
Full Range Leadership Theory (FRL) identifies
three styles of leadership – transformational leadership,
transactional leadership and passive/avoidant leadership
– as a continuum spectrum with nine sub-dimensions.
Transformational and transactional leadership was first
conceptualized by [4], was further brought to light by [5]
and was then expanded upon by Bass, who studied its
application in business, military, and educational settings
[3, 6, 7]
. Transactional leadership is rooted in mutual
exchanges between leader and follower; they contain
contingent reward and management by exception
behaviors. In contrast, transformational leadership is
those behaviors that inspire followers to go beyond the
quid-pro-quo exchange found in transactional behaviors.
Transformational behaviors inspire a higher level of
motivation and morality [5] and influence followers to
expend additional effort that transcends normal
expectations. Transformational leaders provide a vision
to their followers, transform the individual to the
collective, and provide individual support [7-9] describes
transformational leadership as a process of influence on
the follower, and research has supported the effect on a
follower’s attitudes, beliefs, and values [7, 10]. The
outcomes of transformational leadership are well
documented and include a large cadre of organizational
outcomes and individual follower effects [11].
Transformational leadership style is comprised of
four components defined as “4Is” – charisma leadership
or idealized influence (CL or II), inspirational motivation
–attitude and behavior (IM-A&B), intellectual
stimulation (IS), and individualized consideration (IC) [3].
Research has shown these individual elements are highly
correlated, and the measurement of transformational
leadership should be considered an aggregate set of
behaviors [9, 12-15].
Transformational leader is considered as an
effective leader in industry, military and educational
settings [16], and considerable evidences have testified the
effectiveness of transformational leadership. A number
of studies show that transformational leadership has
positive relationship with individual performance [17-28] ,
team /group performance [29-33], and organizational
performance [34-36] in business setting [17, 21, 23, 29, 30, 34] ,
sports setting[18, 36, 37] , military setting[31] , medical
setting[35], school or academic setting[19, 25, 27], R&D
teams or groups[26, 38, 39] and other organizations[32] using
either field study and experiment or quasi-experiment
study[22].
More recently, some scholars are getting interested
in examining the effect of leadership style to creative
performance [40-45] and organizational innovation [46]. The
relationship between transformational leadership and
individual creativity of followers still needs to further
investigation. Especially, the mechanism of the influence
of transformational leadership on followers’ individual
creativity still remains unclear and worth more studies.
2.2 Transformational leadership and leader-member
exchange
Leader-member exchange (LMX) was first
introduced by Dansereau et al. (1975) as vertical dyad
linkage theory (VDL) [47]. To date, LMX has evolved
into a multidimensional construct [48] and is one of the
most studied and useful approaches to understand the
relationship between leader and followers and to
examine the effects of leadership in groups or
organizations. Briefly, LMX reflects a reciprocal process
in the dyadic linkage between leader and follower, in
which followers hold role expectations of their leaders
and they can reject, embrace, or renegotiate roles
prescribed by their leaders [24] and it is premised on
notions of role making [49], social exchange, reciprocity,
and equity [50].
The high-quality LMX relationship reflects not only
the instrumental transactional exchange but also the
affective bonding accompanied by largely unstated
mutual expectations of reciprocity [24]. We argue that
transformational leadership predicts high-quality LMX
because the charismatic leaders appeal to and influence
the followers by building a strong role model and
articulating a clear vision to convince the followers to
believe that this mission is the right thing to do;
inspirational motivation gets the followers to transcend
their own self-interest for the sake of the group, and it
moves followers to address higher level needs [7] which
will raise the group spirit and team support as well as the
relationship between team leader and followers;
according to social exchange theory, transformational
leader with individual consideration trait treats his
followers individually, build the dyadic social and
affective bonding with his followers, satisfies their needs,
assist and motivate them at the dyadic level, which
predict a high-quality LMX.
Although there is a dearth of empirical research
incorporating both LMX and transformational leadership,
it is believed that the transformational leadership is one
of the major reasons to predict high LMX [24, 51, 52].
In educational research teams (ERT), the mentors
with transformational leadership style assist the graduate
students and treat them individually rather than
collectively and consider the individual developmental
needs. Subsequently, they are more likely to build the
affective bonding with the graduate students. Based on
the reciprocal process of LMX, the mentees who
received the mentor’s individualized mentoring and
respect will response to their mentor in a positive way,
which means a high-quality dyadic relationship, in other
word, the high-quality LMX. Consequently, we posit
that high-quality LMX is beneficial for the individual
academic development (in the current study, we use
academic satisfaction and individual creativity) in ERT,
and transformational leadership rather than transactional
leadership predict high-quality LMX.
Leader–member exchange theory posits that the
quality of the relationship developed between a leader
and a follower is predictive of outcomes at the individual,
group, and organizational level of analysis [53].
Consequently, we propose in the current study that LMX
mediates the relationship between the transformational
leadership and the individual creativity in ERTs.
There are several reasons for postulating a link
between transformational leadership and intrinsic
motivation. According to cognitive evaluation
motivation, controlling aspect of rewards decreases
intrinsic motivation[62]. However, transformational
leaders are known to empower, elevate rather than
control their followers [63]. This is supported to some
extent by data showing that a leadership style that is
supportive and promotes autonomy, which would be
consistent with transformational leadership, enhances
intrinsic motivation [64]. This empowering process is
thought to increase followers' self-efficacy and capacity
for self-determination [63].
Transformational leaders stir individuals to think for
themselves, and to approach old problems in new ways.
The intellectual-stimulation component of
transformational leadership is likely to increase
knowledge, learning, and understanding. Similarly,
charismatic leader raises individuals’ and groups’
expectations about what they can achieve and is likely to
increase the accomplishment and task-orientation
component of intrinsic motivation. Transformational
leader, who is supportive and promotes autonomy, will
enhance intrinsic motivation.
Intrinsic motivation is believed to be positively
related with creativity, and numerous studies have
testified this statement [65-73]. We hypothesize in this
study that intrinsic motivation will be a mediator in the
relationship between transformational leadership and
individual creativity.
2.4 Transformational leadership and outcome
variables
Based on the above, we propose the hypotheses in
this paper as follows:
2.3Transformational leadership and intrinsic
motivation
H1: Transformational mentorship is positively related
with individual creativity and job satisfaction.
Motivations are considered as a psychological
process to do a thing. Besides the external rewards or
punishment which drive people to achieve a goal,
researchers found that sometimes people do things
because of their involvement in the thing itself rather
than external factors. Based on the orientation of focus,
motivation can be distinguished into intrinsic motivation
from extrinsic motivation [54].
H2: LMX mediates the relationship between
transformational mentorship and individual creativity.
Intrinsic motivation is defined as the activation of
goal-oriented behavior within an individual due to
internal factors within a person rather than due some
external factors acting on the individual. It reflects
individuals choosing to engage in activities for the
pleasure that they bring [55]. Intrinsic motivation has been
linked to many other dispositions as well as several
aspects of employee behavior [56-61].
H3: Intrinsic motivation mediates the relationship
between transformational leadership and individual
creativity.
H4: An individual’s job satisfaction is positively related
with his/her individual creativity.

Method
3.1 Sample
The participants for this study are the members in
educational research teams in academic settings. We
collected data from 81 research teams, consisting of 258
valid dyadic responses during three-month investigation.
The average age of the sample is 26.22, ranging from 22
to 33, the average size of the team is 8.18, ranging from
2 to 21. There are 107 female graduate students,
consisting of 41.5% of total sample, and 151 male
graduate students, consisting of 58.5% of total sample.
We collected the measurement of transformational
mentorship, LMX, job satisfaction, intrinsic motivation,
self-evaluated creativity from the graduate students, and
collected the creativity rating of the graduate students
from mentors.
3.2 Measurement
3.2.1Transformational Mentorship
Items taken from the Multifactor Leadership
Questionnaire (MLQ) 5X is used to measure
transformational mentorship, including idealized
influence, inspirational motivation, intellectual
stimulation, and individualized consideration [74]. All the
items were changed as referring to “my mentor”, instead
of “my leader”. Although these subscales are
theoretically distinct, in this study, we make no
distinction among the component factors of
transformational leadership. This is consistent with
recent empirical developments on transformational
leadership, which have repeatedly shown that these
dimensions are highly correlated and reflect the highorder construct of transformational leadership [6, 75, 76].
Ratings are completed on a 1 to 5 scale, with 1
representing “Not at all” and 5 representing “Frequently,
if not always”. In the present study, the reliability
coefficient (Cronbach’s alpha) of the transformational
leadership scale is 0.92.
3.2.2 Leader-member exchange (LMX)
This variable is assessed using seven items based on
the member version of leader-member exchange
questionnaires developed and used in prior research [77-80].
Respondents indicate the extent to which the items
characterized the quality of their dyadic relationship with
their supervisors. Ratings are completed on a 1 to 7 scale,
with 1 representing “to a very low extent” and 7
representing “to a very high extent”. In the present study,
the reliability coefficient (Cronbach’s alpha) of the LMX
scale is 0.902.
3.2.3 Intrinsic motivation
The intrinsic motivation scale in this paper is from
WPI (the Work Preference Inventory) scales with 15
items and 2 components – enjoyment and challenge [81].
Ratings are completed on a 1 to 5 scale, with 1
representing “Not at all” and 5 representing “Frequently,
if not always”. In the present study, the reliability
coefficient (Cronbach’s alpha) of the intrinsic motivation
scale is 0.814.
3.2.4 Outcome variables
Satisfaction on the job is measured using a fiveitem scale developed by Bacharach, Bamberger, and
Conley (1991). This general job satisfaction scale
“emphasizes the match between expectations and
perceived reality for broad aspects of the job taken as a
whole” [82]. This scale is also used in other empirical
studies between LMX and job satisfaction [77].
Appropriate to the context of this study, items are
justified based on the tasks in educational research teams.
Ratings are completed on a 1 to 5 scale, with 1
representing “very dissatisfied” and 5 representing “very
satisfied”. In the present study, the reliability coefficient
(Cronbach’s alpha) of the job satisfaction scale is 0.912.
Based on the measurement of individual creativity
in Farmer et al.’s work, four items are justified to
measure the individual creativity in this study [83].
Ratings are completed on a 1 to 5 scale, with 1
representing “Not at all” and 5 representing “Frequently,
if not always”. In the present study, the reliability
coefficient (Cronbach’s alpha) of the individual
creativity scale is 0.84.
Results: Among the 258 valid respondents, 58.5% are
male, and 41.5% are female. The mean of age and team
size are 24.8 and 8.37, respectively. The descriptive
statistics of and correlations between each variables
measured in this study were presented in Table 1.
The results of the construct validity of each
construct using confirmatory factor analyses are
presented in Table 2. As shown, we tested each construct
with their recommended number of factors, and the good
of fitness shows that all the scales measured the
constructs well.

The univariate correlations between
transformational mentorship and individual creativity
and job satisfaction (provide preliminary evidence to
support Hypothesis 1, which states that transformational
mentorship in ERT has positive relationship with the
mentees’ job satisfaction and individual creativity. To
test the following hypotheses, we use the structural
equation models, whose results are presented in Table 3.
job satisfaction and individual creativity. This model
does not have the direct paths from transformational
leadership to job satisfaction and individual creativity.
Because we speculate there is relationship between job
satisfaction and individual creativity, we add the path
from job satisfaction and individual creativity in
transformational leadership and job satisfaction and
individual creativity in model 1-4. As Table 3 shows, all
fit indexes showed a good fit (2 =1649.154, df =1001,
RMSEA =0.05, GFI = 0.792, TLI = 0.9, and CFI =0.907).
Model 1, our baseline model, represents a fully
mediating model. We specify paths from
transformational leadership to LMX and intrinsic
motivation and from LMX and intrinsic motivation to
Against the baseline model, we nest three nested
models. In model 2, we add to a direct path from
transformational leadership to job satisfaction. Model 3
is also identical to model 1, except for the addition of a

Results
direct path from transformational leadership to individual
creativity. In our third nested model, model 4, we add to
two direct paths from transformational leadership to both
job satisfaction and individual creativity. As shown in
Table 4, the differences between chi-squares are not
significant for model 1 compared with models 2, 3 and 4.
Under the principle of model parsimony, therefore, these
results suggest that model 1 best fits our data. We
conclude that leader-member exchange and intrinsic
motivation mediated the relationship between
transformational mentorship and both job satisfaction
and individual creativity. Model 5 and 6 are alternative
models that are not nested within the above four models.
As shown in Table 4, the alternative models are not as
good as the nested models. Figure 1 shows the path
coefficients between the variables. The coefficient of the
path from transformational leadership to LMX is
significant (β = 0.856, p<0.001), as is the coefficient of
the path from LMX to job satisfaction (β = 0.549,
p<0.001), which supported hypotheses 2. The coefficient
of the path from transformational leadership to intrinsic
motivation is significant (β = 0.448, p<0.001), as is the
coefficient of the path from intrinsic motivation to
individual creativity (β = 0.376, p<0.001), which support
hypotheses 3. In addition, there is significant coefficient
of the path from job satisfaction and individual creativity.

Conclusion and discussion
Mentorship in educational research teams is as
important as leadership in other teams in common
organizational settings. This study investigated the
effectiveness of transformational leadership in a special
context – education research team which is an important
context for developing the potential researchers in the
relevant fields based on human capital theory.
Recently, how transformational leadership affects
performance has begun to attract empirical scrutiny.
Early evidence suggested that transformational
leadership affects performance indirectly via several
mediating mechanisms, like self-efficacy beliefs [23, 84],
affective commitment [85], trust in management [85],
LMX[24], empowerment [86], job characteristics[87] and
intrinsic motivation in sports setting [18]. This study
contributes to the leadership theory by investigating the
conceptual and empirical links between transformational
leadership and leader-member exchange. Another
mediator—intrinsic motivation shows that how
transformational leadership influences on the members’
creativity in a special context.
The findings in the current study are consistent with
the notions that: (1) transformational leadership
behaviors are social currency, nourishing high-quality
LMX; (2) transformational leadership is effective in
most contexts and positively related with the outcome
variables such as job satisfaction; (3) transformational
leaders enhance member receptivity to role-expanding
offers and extra-role behaviors through processes of
personal and /or social identification [24]; (4)
transformational leaders enhance the intrinsic motivation
of members which infers to an enhancement in members’
creativity.
6.
Limitation and future study
Firstly, using the graduate student samples to test a
general theory limits the generalization of the results.
Although we articulate that the investigation is for the
educational research teams, we hope that the results
could be generic across the samples, however, the
sample limits the generalization of this study. In the
future, the framework of the study should be testified in
other team settings,
Secondly, our study was cross-sectional design
which made it difficult to understand the dynamic
process how LMX formed from the beginning and
forged by the leadership behaviors. In the future, the
longitudinal design is needed for understanding the
process. Furthermore, although there are linkages
between transformational leadership and LMX from the
theoretical perspective, the empirical evidences are
limited [24, 51, 52]. This paper adds evidence to this theory
linkage and we also consider that the relationship
between transformational leadership and LMX will be
moderated by the characteristics of individual differences
such as the personality which could be tested in the
future studies.
7.
Practical implications
Overall, our findings suggest that effective leadership
express their transformational behaviors within a
personal,
dynamic relational exchange context [24] in the
educational research teams. Job satisfaction and
individual creativity are the important indexes reflecting
the performance and effectiveness of educational
research teams and leadership style is one of the vital
factors to influence these performance and effectiveness
in ERT. The findings in this study provide evidence to
suggest a transformational leader in ERT because its
effectiveness in building the high-quality LMX and
enhancing the intrinsic motivation of followers, which
are the key process predicting the positive influence on
the outcome variables, in this study, the job satisfaction
and creativity.
Additionally, our findings provide insights into how
high-quality leader-member exchange relationships can
be developed and how it enhances the intrinsic
motivation of followers. The previous LMX literature
focuses strongly on the outcomes of high-quality leadermember exchange, giving less attention to its antecedents.
The extent transformational leadership literature has a
primary focus on performance-enhancing leader
behaviors. The intrinsic motivation literature focuses on
the rewards and external limitation’s influence on the
intrinsic motivation. Our findings suggest that (1)
transformational leadership are instrumental to
developing high-quality LMX relationships [24]; and (2)
the appropriate leadership – the transformational
leadership also enhances the intrinsic motivation of
followers. For the educational implication, results of this
study shed some lights on how to create a nurturing
context to increase the members’ creativity via
leadership behaviors in order to better the quality of
higher education.
