Abstract: Integrity is the center of leadership. Leadership style has a theoretical or contextual foundation that has a
relationship with integrity. This study aims to analyze the continuum of integrity in leadership style. Five
leadership styles, including adaptive leadership, servant leadership, transformational leadership, ethical
leadership, and authentic leadership, are examined in relation to integrity. The research conducted with
literature review method in the form of context, theory, instrument, and character of leadership style that have
a relationship with integrity. The results showed ethical leadership has the highest degree of continuum
integrity while adaptive leadership has the lowest degree of continuum integrity. In the public sector,
especially the government, it is more favorable to develop ethical leadership.
1 INTRODUCTION
The development of the corruption level in Indonesia
remains on ranks 89th in the world and yet still far
behind Singapore (3) and Malaysia (69) based on the
Corruption Perception Index (CPI) report in 2018
(Transparency International, 2019). Despite the
increasing number of arrests from elite politicians by
the Indonesian anti-corruption commission, the level
of Indonesian state political corruption stays high
(Mietzner, 2015). It shows that there is an error in the
party's financial system (Mietzner, 2015), also due to
unclear leadership (Von Luebke, 2010).
Weak leadership extends corruption. Various
literature relates to corruption with weak leadership
(Imhonopi and Ugochukwu, 2013; Owoye and
Bissessar, 2014). Leadership becomes the spearhead
of corruption eradication, in addition to a support
system.
One of the main characters in leadership is
integrity (De Braine and Verrier, 2007; Grahek,
Thompson and Toliver, 2010; Mihelic, Lipicnik and
Tekavcic, 2010; Liborius, 2017). Integrity has to be
based on morally justifiable principles. One does not
have integrity as a virtue by taking any value as a
reference. Integrity means acting on the ideas that
exist in the value system, adherence to moral and
ethical principles, healthy moral character, honesty,
personal value systems and values that are
implemented (Storr, 2004; Goldman Schuyler, 2010;
Bauman, 2013).
Previous studies have linked leadership style with
the character of integrity, transformational leadership
with integrity (Harrison, 2011; Clarke, 2013;
Liborius, 2017), ethical leadership with integrity
(Mihelic, Lipicnik and Tekavcic, 2010; Engelbrecht,
Heine and Mahembe, 2017), and authentic leadership
with integrity (Leroy, Palanski and Simons, 2012;
Peus et al., 2012). A study by Arredondo Trapero &
Maldonado de Lozada, (2010) only compared the
degree of integrity of transformation leadership with
transactional leadership. This study is in the form of
analyzing the continuum of integrity from the five
existing leadership styles, namely authentic
leadership, adaptive leadership, servant leadership,
transformational leadership, and ethical leadership.
2 METHOD
This study utilizes the literature review method as
many as 40 previous journals that have been selected
due to the links with the concept of integrity. First, the
structure of the first review and the content or context
of the leadership style were extracted to summarize
the relationship with integrity. Second, we consider
the theory or approach that explains the leadership
style of its purpose to describe the theory that
develops into the leadership style integrity behavior.
Third, reviewing leadership style measurement
instruments that provide insight into integrity.

3 LITERATUR REVIEW
The use of integrity in the leadership literature varies.
Some integrity discussions define integrity as a
common moral concept, while others interpret it as
honesty, trust, and authenticity (Bauman, 2013).
Another discussion claims that "moral character" is
an important characteristic of an effective leader.
Integrity has a prevalent meaning in regard to
moral honesty and/or integrality. Integrity in the
philosophy has two general meanings namely i) one's
personal integrity consistently acts based on
commitment, regardless of its ethical content, and ii)
individuals who have a solid commitment to
appreciate others and consistently behave
respectfully (Bauman, 2013). Previous studies also
linked integrity with leadership (Storr, 2004;
Goldman Schuyler, 2010; Day et al., 2014; Zaker,
Nawaz, and Khan, 2016). In brief, integrity regarding
moral concepts can be seen in Table 1 below:

Various theories of leadership and academic
literature occasionally seem difficult for practitioners
to comprehend due to the complex
conceptualizations, unclear terms, and variety (Van
Wart, 2013). Development of effective leaders and
leadership behaviors is a major concern in all types of
organizations (Day et al., 2014).
There are various styles of leadership produced by
several studies, including servant leadership,
transformational leadership, adaptive leadership,
ethic leadership, and authentic leadership. The
servant leadership style was coined by Greenleaf
(1970), and transformational leadership by Bass
(1985), adaptive leadership by Heifetz (1994), ethic
leadership began by Cuila (1998) and the
development of transformational leadership became
authentic leadership by Chan (2005).
In servant leadership, one is striving to be both a
leader and a servant (Greenleaf, 1970). Servant
leadership provides the perspective of the leader and
his behavior (van Dierendonck, 2011). Focus on
follower issues, empathy, empowering, developing
capacity, and caring for followers. It is in contrast to
transformational leadership that gives attention to
charismatic and effective. Transformational
leadership emphasizes on intrinsic motivation and
follower development, which is in line with the needs
of the current working group, which wants to be
inspired and empowered to succeed during
uncertainty (Riggo and Bernard M, 2010).
In adaptive leadership, instead of seeing leaders as
saviors who solve people’s problems, they
conceptualize leaders as people who play the role of
mobilizing people to overcome difficult issues. An
adaptive leader encourages others to confront tough
challenges, giving them the necessary place or
opportunity to acquire new ways in dealing with the
inevitable changes upon perceptions, assumptions,
attitudes, beliefs, and behaviors that they may face
when controlling real problems (Useem, 2010) —
whereas authentic leadership uses an intrapersonal
approach, showing sincere leadership, leading from
beliefs, and originals, not copies. This perspective
emphasizes the life experience of a leader and the
meaning attached to these experiences as important
for the development of authentic leaders (Northouse,
2010).
4 RESULT AND DISCUSSION
The utilization of integrity in various leadership
literature varies. Some people describe integrity as a
common moral concept, while others define it in more
details and relate it with honesty, trust, and
authenticity (Bauman, 2013). There was an emerging
idea which stated that “moral character" as a key
characteristic of effective leaders and it did not use
the word "integrity," another discussion of ethics and
morality is included when developing leadership
theory (Bauman, 2013). The discussion on the
Continuum of integrity in leadership style begins by
looking at the concepts/lessons, approaches/theories,
instruments, and characters of each leadership style.
Adaptive leadership is concerning on how leaders
drive people to adapt, to confront and deal with
problems, challenges, and changes (Yukl and
Mahsud, 2010). Adaptive leadership focuses on the
Integrity in Leadership Style Context: A Review
63
adaptations that people need to respond to changing
environments. As for some techniques can be applied
such as create a personal link with everyone; act fast,
don't wait for perfection; make the organization the
top priority and set direction by giving people
freedom of creation (Useem, 2010).
Adaptive leadership is more focus on followers.
Adaptive leadership deals with how people shift and
adapt to new circumstances. It can be seen as a
practice of mobilizing people to overcome difficulties
and developing challenges "(Heifetz, Grashow, and
Linsky, 2009). The purpose of adaptive leadership is
to push people to transform and discover new ways of
life so they can do well and grow. In short, adaptive
leadership is the behavior of the leaders and the
actions they lead to push others to outgrow and
resolve important changes in their lives.
The situational approach can explain the strategies
and behaviors that encourage learning, creativity, and
adaptation in complex organizational systems.
Adaptive leadership is described as a complex
process that appears to produce an adaptive change in
social systems (Northouse, 2018). In brief, adaptive
leadership can be seen in Table 2.

The next leadership style is servant leadership.
This leadership style lacks institutional power and
control (Greenleaf, 1970). Servant leadership is
unique because it makes altruism a major component
of the leadership process in line with the degree of
integrity (Brewer, 2010). Servant leadership operates
from altruistic patterns. These leaders have a high
level of integrity, and the compatibility between the
values held and enforced provides a basis for moral
authority (Parris and Peachey, 2013). These leaders
also invite supervision from others who have
permission to question their motives and challenge
leaders to use power based on their position
(Whittington, 2017).
Servant shows strong moral behavior towards
followers, organizations, and other stakeholders
(Ebener and O'Connell, 2010). Everyone can learn to
be a serving leader. This shows the relationship with
the integrity of the leader. The relationship of
followers with leaders includes ethical and belief
aspects. Trust is built with utmost honesty and
openness, keeps actions consistent with values, and
shows trust in followers (Focht and Ponton, 2015).
Various questionnaires have been developed to
measure servant leadership (Van Dierendonck and
Nuijten, 2011; Gini and Green, 2014; Liden et al.,
2015). Servant Leadership Questionnaire (SLQ)
arranged by measuring seven main dimensions of
servant leadership; conceptualization, emotional
healing, prioritizing followers, helping followers
grow and succeed, behave ethically, empower, and
create value for society (Liden et al., 2015). The
various questionnaires use judgments about the
integrity, authenticity, and stewardship of leaders.
Characteristics include trust, integrity, comfort
with ambiguity, and openness to change. Integrity and
humility are very important to turn into serving
leaders who in turn are needed to "empower, and
develop others in carrying out the tasks and processes
of vision, goal setting and leading (Spears, 2010;
Beekun, 2012; Mittal and Dorfman, 2012; Davis,
2017). Broadly speaking, servant leadership can be
seen in Table 3.
In the Transformational leadership style, the
research focus has been developed since the early
1980s. Transformational leadership is part of the
paradigm of "New Leadership," which interest in
charismatic and affective (Rolfe, 2011).
Transformational leaders play an important role in
accelerating change; followers and leaders are
engaged in the transformation process.
Transformational leadership is more expanded and
refined based on giving more attention to the needs of
followers than the needs of leaders, by suggesting that
transformational leadership can be applied to
situations where results are not positive (Riggo and
Bernard M, 2010).

stewardship, commitment to
people growth, and building.
Bass (1985) argues that transformational
leadership encourages followers to do more than
expected by (a) increasing the level of follower
awareness regarding the importance and goals value
that is determined and idealized, (b) getting followers
to go beyond themselves - interests for the team or
organization, and (c) mobilize followers to meet
higher level requirements. The elaboration of the
dynamics transformation process is provided in
transformational and transactional leadership models
(Bass, 1985).
Transformational leadership can be judged
through the use of the Multifactor Leadership
Questionnaire (MLQ), which evaluates leader
behavior in seven areas; ideal influence (charisma),
intellectual stimulation, inspirational motivation,
individual consideration, contingent gifts, exception-
management, and laissez-faire (Northouse, 2018).
The results showed that transformational leaders
are considered to have more integrity and are more
effective than non-transformational leaders
(Arredondo Trapero and Maldonado de Lozada,
2010). Transformational leaders, especially those
who have the inspirational motivation and intellectual
stimulation, are more likely to behave ethically in
organizational activities (Harrison, 2011; George
Ogbonna, 2013; Hutchinson and Jackson, 2013;
Mccleskey, 2014; Banks et al., 2016). In brief,
transformational leadership is seen in Table 4.

The following leadership style is authentic
leadership. Authentic leaders are able to assess
ambiguous ethical issues, view from a variety of
perspectives, and align decisions with their own
moral values. Authentic leaders have the potential to
act ethically because they have an internalized moral
perspective and commitment to core ethical values
((Gardner et al., 2011; Avolio and Mhatre, 2012).
Dedication to this moral life is demonstrated through
efforts to achieve integrity behavior from time to time
and serves as an important antecedent of ethical
leadership and authentic leadership behavior.
The definition of authentic leadership has been
proposed by previous research (Yukl and Mahsud,
2010; Avolio and Mhatre, 2012). The definitions are
diverse but emphasize the importance of the leader's
integrity. The authentic leader has positive core
values (e.g., honesty, fairness, kindness,
accountability, and optimism) that motivate them to
do what is right and fair for their followers. These
leaders create special types of relationships that
include high mutual trust, transparency, shared goals,
and an emphasis on the welfare and development of
the followers.
The behavior of the core components includes
keeping the leader's actions consistent with the values
adopted and actual, articulating interesting visions,
modeling appropriate behavior, and expressing
optimism and encouragement when there are
problems in achieving task objectives (Peus et al.,
2012; Northouse, 2018 ). Most researchers described
authentic leaders as being honest with themselves and
showing a high level of moral integrity (Luthans &
Avolio, 2003). The moral integrity of authentic
leaders is established when their values are aligned
with their behavior in the course of time and cross
various situational challenges.
The instrument developed in the form of
Authentic Leadership Questionnaire (ALQ) was
created by Walumba and the colleagues (Walumbwa
et al., 2008). ALQ identifies and measures four main
authentic leadership’s components; self-awareness,
internalized moral perspectives, balanced processing,
and relational transparency (Walumbwa et al., 2008;
Northouse, 2018). In addition, researchers have
discovered that authentic leadership is affected by a
leader's positive psychological capacity, moral
reasons, and critical life events. Furthermore,
authentic leadership has several positive features
(Leroy, Palanski, and Simons, 2012). An outline of
authentic leadership is shown in Table 5.

The last explanation about ethical leadership. One
of the earliest writings focusing on ethical leadership
began in 1996, then appeared in ethics as the Heart of
Leadership (Ciulla, 1998). Ethical leadership uses an
ethical theory which serves a set of fundamental
guide for leaders in the decision-making process,
especially about how they have to act and how to be
morally feasible (Northouse, 2018).
Eisenbeiss' study (2012) analyzed the similarities
between Western and Eastern moral philosophies and
ethical principles of world religions, from ethical
leadership, has four central ethical orientations: (1)
human orientation, (2) responsibility orientation
responsibility and sustainability, (3) justice
orientation, and (4) moderation orientation. The
principle of leadership leads to integrity.
Empirical studies have also shown a joint
relationship between leader integrity and work
engagement through the mediating role of ethical
leadership (Engelbrecht, Heine, and Mahembe,
2017). The constructs of ethical leadership think
about the long-term consequences, weaknesses, and
benefits of the decisions they make in organizations
(Brown and Mitchell, 2010; Lawton and Páez, 2015).
Ethical leaders are humble, strive for justice, care
for the greater good, take responsibility, and
appreciate each individual (Mihelic, Lipicnik and
Tekavcic, 2010). Ethical leaders set high ethical
standards and act accordingly. Ethical leaders
influence organizational ethical values through
behavior. Leaders function as role models for their
followers and demonstrate the limits of behavior set
in an organization (Northouse, 2018). Ethical
leadership is considered honest, courageous,
trustworthy, and promotes integrity. The more leaders
"walk the talk," by translating internalized values into
action, the higher the level of trust and respect that
results from the followers.
The ethical leadership measurement developed by
Craig and Gustafson (1998), namely the Perceived
Leader Integrity Scale (PLIS), which is extracted
from utilitarian ethical theory. The PLIS seeks to
evaluate the leader's ethics by measuring the extent to
which coworkers see it acting according to rules that
will generate the greatest good for the greatest
number of people. An outline of ethical leadership
can be seen in Table 6.

Based on the explanation of the various leadership
styles that exist from adaptive leadership to ethical
transformation, the conclusions can be drawn
regarding the continuum of integrity from the aspects
of the concept, theory, instrument, and character.
Ethical leadership has the highest degree of integrity
based on existing literature studies. They are starting
from the concept of the formation of ethical
leadership that refers to moral values. This is related
to integrity. Likewise, the developing theories,
instruments, and characters that were raised by
several previous researchers. Ethical leadership and
authentic leadership have basic similarities, so
authentic has a high degree of integrity. In contrast to
adaptive leadership which focuses more on adjusting
to the internal and external environment, the
connectedness with the concept of integrity is quite
low, so it has a low degree of integrity.
Servant leadership focuses on the service to their
followers whereas transformational leadership
focuses on inspiring their followers to achieve their
desired vision. Based on the theory and formed
instruments and characters, transformational
leadership has a fairly high degree of integrity
compared to servant leadership. According to the
existing concepts, theories, instruments, and
characters, the continuum of integrity in leadership
style can be designed as shown below.

5 CONCLUSIONS
Yahaya & Ebrahim's (2016) empirical study proved
that there is a correlation between leadership style and
organizational commitment. This encourages
organizations to develop leadership styles that are
appropriate for their conditions. Another empirical
study by Arredondo Trapero & Maldonado de Lozada
(2010) pointed out different levels of integrity in
testing different leadership styles. The leader style
shows the main values that are carried on the leader.
There is a continuum of the leadership of the highest
leadership style in ethical leadership. In public
services, especially the government sector needs to
encourage ethical leadership. Further research may
conduct empirical studies by testing the continuum of
integrity in leadership.
