ABSTRACT
Public service motivation (PSM) and civil servant job performance are primary concerns in
government. As a result, utilizing the PSM Model, this study was undertaken to analyze
employee motivation in the public sector. Commitment to the public interest is one of the
model's components. This study aims to look into the link among PSM, organizational
commitment, work performance, and the impact of empowerment and job characteristics. The
study analyzed a data collection of 499 public servants in Ho Chi Minh City, Vietnam, where
public sector organizations are characterized by a culture of high-power distance,
collectivism, and a high level of bureaucracy. The findings show that PSM is positively
affected by empowerment and job characteristics, which in turn can enhance the
organizational commitment and job performance among public servants. At the same time,
the skill variety, task significance, task identity, feedback, and autonomy do not affect the job
performance among public servants.
Keywords: Public service motivation; empowerment; organizational commitment; job
characteristics; job performance, public sector.
1. INTRODUCTION
The essential sector in the national administration is a public organization, which must be
relevant and approved by society. Government agencies are constantly working to enhance
the quality of public services, yet the general public has the impression that government
personnel is less productive than private enterprises (Frank & Lewis, 2004; Liu & Chen,
2021). It indicates that private-sector owners will pressure management agents to focus on
productive efficiency and profitability, given that profit maximization is important to them.
They require the highest potential productivity to achieve it (Aguilera et al., 2021). Public
service motivation (PSM) is vital for community life and organizational management. It is a
noble virtue for creating quality living at all levels and systems (Ritz et al., 2016). As a result,
whether for business or non-profit enterprises, organizational commitment to PSM activities
is essential to enhance organizational performance and attain competitiveness (Clerkin &
Fotheringham, 2017). Furthermore, PSM predicts public employees' job satisfaction, ethical
behaviors, and performance (Chen et al., 2021).
Much research has investigated employee work motivation in the previous few
decades (Islam & Ismail, 2008). Since PSM was first defined as an individual's predisposition
to react to incentives mainly anchored or exclusively in public institutions and organizations
(Perry & Wise, 1990), the field has evolved significantly. However, scholars have found
similar conceptual and practical disagreements and a lack of clarity in the knowledge base
when periodically assessing this proliferation of studies, including various definitions
associated with PSM (Bozeman & Su, 2015; Esteve & Schuster, 2019). The use of different
measurement scales (Coursey & Pandey, 2007; Kim et al., 2013; Perry, 1996; Vandenabeele,
2008; Wright et al., 2013), a debate over the fundamental nature of the concept (e.g., is PSM
a stable state of being or a trait that can be developed over time or reduced through poor
management) (Giauque et al., 2013; Holt, 2019; Van Witteloostuijn et al., 2017; Vogel &
Kroll, 2016), a dispute about the relationship between PSM and other organizational behavior
ideas like altruism and prosocial behavior (Boyd & Nowell, 2020; Breaugh et al., 2018;
Nowell et al., 2016; Piatak & Holt, 2020). PSM is an area with comparable consensus in terms
of relevance and ongoing conceptual and measuring issues (Piatak et al., 2020). Based on
established theories, PSM can yield beneficial outcomes (Huang, 2019), mainly when
government workers' prosocial incentives are bolstered, whereas there is no link discovered
between PSM and public organizations by some scholars (Moynihan & Pandey, 2007a,
2007b). In other words, the outcomes are ambiguous, which might be attributable to the
influence of other factors.
Trying to uncover whether people who work in the public sector (broadly defined) are
motivated by specific public service-oriented reasons and what this entails for public service
organizations and policies. PSM has developed as one of the most important and popular
topics in public administration research over the last two decades, with hundreds of studies
studying what PSM is, how to quantify it, how organizational processes influence PSM, and
how PSM influences both personal and organizational outcomes (Christensen et al., 2017).
More study on how PSM relates to the practice of public administration—what practical
lessons can be gleaned from this vast body of knowledge to guide the employment experience
on the ground—has been requested by academics (Christensen et al., 2017; Ingrams, 2020;
Jensen, Andersen, & Holten, 2019; Jensen & Vestergaard, 2017; Miao et al., 2018; James L.
Perry & Vandenabeele, 2015; Piatak & Holt, 2020; Ripoll, 2019; Ritz et al., 2016;
Vandenabeele et al., 2014; Wright et al., 2013). Despite the current increase in study interest,
primary theoretical problems concerning the relationship between PSM and job performance
in the public sector remain to be addressed. Particularly in the Vietnamese public industry
with strong effects of Confucianism, cultures of harmony, collectivism and face-saving as
well as cultural patterns of obedience, paternalism, and fatalism, which make employees
passive and reluctant to take the initiative and responsibility. Therefore, unlike developed
countries, public sector organizations are characterized by collectivism, high bureaucracy,
and a high power distance culture (Nguyen et al., 2020). It has generated a poor work ethic,
opportunism, carelessness, wastefulness, and arbitrary decision-making.
Vietnam shares many issues in common with other emerging and transitional nations,
including low productivity, widespread corruption, inefficiency, "red tape," and power abuse.
We reply to the requests to investigate causality concerns and the boundaries of PSM by
discovering factors that may be related to PSM. How highly public service motivated civil
servants to perform in public organizations; and whether PSM positively impacts
organizational commitment, which leads to better job performance in the public sector. Then
the findings suggest management recommendations and practices for boosting employee
efforts in public organizations, especially in Vietnam and countries with the same cultural
factors and patterns.
Empowerment
Empowerment is a term that characterizes working situations in which the empowered is
emotionally involved (Echebiri et al., 2020). It is argued that empowerment is achieved by
decentralization, flattening the hierarchy, and more employee engagement. Empowering
employees entails giving them decision-making authority, discretionary power, autonomy,
and flexibility (Norbu & Wetprasit, 2021). Employee empowerment is described as creating
drive and self-efficacy in employees to remove their helplessness (Jung et al., 2020).
Empowerment as a "feeling of authorization to act" may be viewed as a form of power (Smith
et al., 2019). Empowerment is concerned with one's sense of power and allows one to
participate. On the one hand, the majority of the concept studies included looked at
empowerment from three perspectives: 1) antecedents, 2) qualities, and 3) outcomes
(Halvorsen et al., 2020).
On the other hand, previous literature on empowerment showed that two significant
ideas of empowerment have steadily formed through time. These are social-structural and
psychological approaches (Echebiri et al., 2020). The structural approach focuses on the
conduct of leaders who empower others. Empowering leadership is defined as leading by
example, participatory decision making, guiding, informing, and demonstrating care. Another
aspect is psychological empowerment, which is concerned with how empowered employees
feel (Rafique et al., 2021; Wang & Yang, 2021). Furthermore, social–structural empowerment
is concerned with workplace social structures and environmental elements on a broad scale,
while psychological empowerment stresses a psychological standpoint or micro-level
cognition.
Empowering leadership may be antecedents of psychological empowerment, for
instance, individual-level psychological and group-level psychological empowerment
(Cheong et al., 2019). Empowering leadership is conceptualized as how leaders distribute
power from themselves to their subordinates (Echebiri et al., 2020; Thun & Bakker, 2018).
Empowering leadership entails five major actions: leading by example, participatory
decision-making, coaching, educating, and expressing concern/interacting with the team
(Kim, 2019). It implies a growing idea of sharing increasingly extended responsibilities and
essential leadership specialists over work and assets and the assistance needed to handle the
added assignment (Alameri et al., 2019). In the current study, empowering leadership involves
(1) power sharing, (2) motivation support, and (3) growth support (Kim & Beehr, 2020). This
research defined empowerment as a motivating idea that focuses on empowering individuals
and promoting personal growth. Empowerment attempts to instill in followers a proactive,
self-confident attitude and a sense of personal strength and give employees decision-making
participation, coaching, and information (Kim, 2019; van Dierendonck & Nuijten, 2011).
Organizational commitment
The proportional strength of an individual's identification with and engagement in a specific
organization is how organizational commitment is described (Murray & Holmes, 2021; Park,
2020). Traditionally, an organizational commitment was defined as the degree to which an
employee identified with the organization's goals (Ruiz-Palomo et al., 2020). Also, an
emotional connection to an organization is also defined by organizational commitment (Borst
et al., 2020). The organizational commitment of employees can be shown in three ways:
affective commitment, continued commitment, and normative commitment (Pratono et al.,
2019).
On the other hand, organizational commitment is a stage in which an employee
identifies a specific group with specific aims and wants to remain a part of that group
according to (Eliyana et al., 2019). Moreover, they demonstrate employees' commitment to
the organization and the next stage in which organizational members exhibit concern for the
company's success and future development. Work engagement is concerned with job
performance, whereas commitment is concerned with the psychological link that exists
between the person and the organization (Meijerink et al., 2020), which is created as a result
of the employee's relationship with the organization when the organization treats its
employees with respect (Miao et al., 2019). Of interest, this study refers to organizational
commitment to a person's emotional attachment to, identification with, and participation in a
company (Battistelli et al., 2019).
Job performance
Job performance is a variable at the individual level or something that a single person does in
an organization (Qureshi et al., 2019). Reviewing employees' job quality and productivity can
help organizations manage their in-role performance and contribution or whether the
personnel are capable of performing their job responsibilities (Lin & Huang, 2020). Similarly,
performance (in-role behavior) is defined as what is demanded or anticipated as part of the
workers' formally allocated duties and obligations (López-Cabarcos et al., 2020). According
to (Marzec et al., 2020), job performance is defined as an individual's overall expected value
to the organization of discrete behavioral episodes performed over a set period. Job
performance is a level of achievement in which a person from the company completes a task
(Eliyana et al., 2019), referring to scalable activities, behaviors, and results that employees
interact with or contribute to within businesses (Davidescu et al., 2020). Performance is a
result or degree of the overall success of a person in carrying out a task over a specific period
when compared to other alternatives, such as standard work outcomes, targets, or target
criteria that have been set and agreed upon in advance (Pratono et al., 2019). In the current
research, job performance refers to employee behaviors critical to the organization's success
(Talukder et al., 2018).
Empowerment and PSM
Recent research has focused on the potential benefits of servant leadership, finding that it
positively impacts government employees' behaviors and attitudes such as justice perception,
trust, PSM, organizational commitment, organizational citizenship behavior, and performance
appraisal acceptance (Shim & Park, 2019). According to self-determination theory,
empowering leaders may be conceived of as contextual support that ignites workers'
autonomous motivation, inspiring them to speak up (Gao & Jiang, 2019).
The personnel is given sufficient room and discretion by their empowering-style
supervisors, prompting them to take on projects on their own initiative. In today's industry,
empowered leadership has lately been proven to drive proactive behaviors (Wang & Yang,
2021). Recognizing the significant differences between the public and private sectors, it is
argued that public administration scholars should focus on collective approaches to
leadership, which share a common tradition of concern for the goals of leaders and followers.
They concentrate on leader-follower relationships and strategies that emphasize inclusivity
and empowerment, as these theories fit well with the study of prosocial attitudes like public
service (Hameduddin & Engbers, 2022). Empowering leadership increases their autonomy
and motivation at work by providing feedback and opportunity for workers to enhance their
skills and expertise (Gao & Jiang, 2019; Han et al., 2020; Wang & Yang, 2021).
Workers' empowerment might boost job enrichment and their duties and motivation
(Ruiz-Palomo et al., 2020). Because it increases the purpose and meaning of work by giving
employees authority and freedom to make decisions during service delivery, empowered
leadership is the most relevant and effective way to influence service-oriented civic behaviors
(Lin et al., 2019). When frontline service employees affect the service encounter, it results in
customer-focused behaviors such as the capacity and willingness to improve service
performance, leading to higher customer satisfaction (van Esch et al., 2020). Employees are
expected to meet their autonomy, competence, and relatedness. Therefore, empowering
leadership emphasizes autonomy and encouragement. It may help to boost intrinsic
motivation (AlKahtani et al., 2021; Cheong et al., 2019; Kim, 2019; Mutonyi et al., 2020). It
enables employees to respond to customer service requests more rapidly, deal with complaints
more swiftly, and engage more in service encounters (Echebiri et al., 2020). It supposes that
administrative reforms such as empowerment, decentralization, and the reduction of red tape
boost PSM (Liu & Chen, 2021).
Empowerment and Job Characteristics
Job Characteristics
Job characteristics were grouped into diversity, autonomy, operational interaction, knowledge
and skill, and responsibility early in the job characteristics theory, which has drawn attention
since 1965 (Yoon et al., 2020). Job characteristics are the elements of core duty qualities that
convey perceptions about the importance, responsibility, and outcome felt when executing the
job independently. Employees think about the meaning and significance of the job because of
skill variety, task identity, and task significance; autonomy gives them a sense of
responsibility for the job; and feedback gives them a psychological state to perceive the actual
result of business activities (Hwang & Jang, 2020).
Job characteristic model is defined with five core job characteristics of one's position,
including skill variety (the degree to which a job requires the use of multiple skills), task
identity (the degree to which a job requires completion of a whole, from start to finish), task
significance (the degree to which one's job has a significant impact and meaning on other
people's lives or work), task autonomy (the degree to which one's job provides substantial
independence and freedom), and feedback (the degree to which the job provides direct and
clear assessment on how effectively one has performed) (Cai et al., 2019; Garg, 2019; Han et
al., 2021; Howard & Cogswell, 2019; Hwang & Jang, 2020; Issahaka & Lines, 2021; Othman
& Nasurdin, 2019; Wang, 2020).
Job autonomy, task diversity, and skill variety are essential motivating job
characteristics (Zhang & Parker, 2019). Job routineness (predictability), job specificity (the
degree to which job tasks and importance are defined), human resource development, and
feedback are all characterized as job characteristics of public employees (Park, 2020). On the
other hand, job demands and resources are considered two major categories of job
characteristics that may explain employee energy depletion and motivation, respectively
(Amor et al., 2021; Parola et al., 2019). Job demands are elements that need energy to address,
whereas job resources assist employees in meeting these demands (Borst et al., 2020).
However, it is stated that job characteristics should include job autonomy, job security, and
pay (Kim et al., 2021).
Additionally, hours worked, job demands, job control, workplace support, and role
overload are all components of the job characteristics (Creed et al., 2020). Regardless of the
variety, the current study adopts five job characteristics of skills variety, task significance,
task identity, task autonomy, and feedback. The degree of experienced meaningfulness of the
job is determined by the first three characteristics (i.e., skill diversity, task identity, and task
importance). Of the remaining two dimensions, autonomy relates to the degree to which an
individual recognizes how effectively he or she is doing the task, and feedback mentions the
degree to which an individual realizes how effectively he or she is executing the work (Hwang
& Jang, 2020).
Empowerment increases employee motivation by increasing their feeling of meaning
in their job. As a result, work performance increases (Yin et al., 2019). Positive job
characteristics and proactive work behavior are influenced by empowering leadership.
positive outcomes (internal work motivation, quality work performance, job satisfaction, and
low absenteeism) (Allan et al., 2019).
Leaders may help people have a favorable perspective of their occupations, and this
perception serves as a critical mediator for self-generating motivation and goal commitment,
which leads to emotionally organizational outcomes and task performance outcomes (Han et
al., 2020). Relational job design characteristics may impact PSM (Piatak et al., 2020). Intrinsic
motivation is influenced by context, has a sizeable dispositional component, and can be linked
to job characteristics (e.g., autonomy, feedback, skill variety, task identity, and task
significance), with some jobs (frontline jobs) requiring more direct customer interaction and
thus being more motivating than others (back-office jobs) (Ruiz-Palomino & Zoghbi-
Manrique-de-Lara, 2020). However, variables such as age and gender influence PSM levels
between people, and variables such as job characteristics may impact PSM within people
(Parola et al., 2019). Changes in relational job characteristics will be linked to prosocial
motivation, defined as "the desire to help others or invest effort out of care for others." (van
der Voet & Steijn, 2021). Job characteristics can boost work effort and task performance by
activating prosocial motivation and keeping staff naturally engaged while doing assigned
responsibilities (Garg, 2019). Employees and organizations may experience essential
outcomes such as intrinsic motivation, job performance, job satisfaction, and work
effectiveness as a result of job characteristics (i.e., experienced meaningfulness of the work,
responsibility for work outcomes, and knowledge of results) (Hwang & Jang, 2020).
Job characteristics and job performance
Service employees need autonomy and flexibility to respond quickly to clients' unique,
changing expectations (Lin et al., 2019). When the notion of job characteristics is highlighted,
which outlines external activities that might influence employees' work opinions, it results in
internal job satisfaction and improved work performance (Wang & Yang, 2021). The firm
created a reciprocal climate by giving convenient employment features (e.g., job security and
flexibility) in which workers repay an excellent work environment with higher retention and
better job performance (Rahimnia et al., 2019). Also, employee performance is influenced by
factors such as self-determination, job stability, authority, responsibility, and autonomy,
comfortable workplace, advancement prospects, welfare packages, professional
development, job attractiveness, remuneration, effective management-employee
communication, early task distribution, a sense of recognition, and a competitive salary
(Davidescu et al., 2020).
Five core motivational job characteristics include task identity, task significance, skill
variety, job feedback, and autonomy. When they are combined, it creates a job's motivation
potential, which determines positive outcomes such as internal work motivation, positive
attitudes toward the job such as job satisfaction, organizational engagement, job participation,
and performance quality and quantity (Kulikowski et al., 2022) or creativity, organizational
citizenship behaviors, employee health and well-being (Naseer et al., 2020). Job
characteristics influence psychological states, which shape personal and professional
outcomes (Wang & Yang, 2021). As a result, job characteristics are essential environmental
antecedents to proactive work behavior, and job autonomy gives employees flexible work
control by allowing them to adjust in their workplace. Meaningful work is a significant
psychological feature that contributes to increased job satisfaction, better work performance,
and lower turnover (Rai & Maheshwari, 2021). Workers perceive a high level of meaningful
work when their job qualities and duties coincide with their own beliefs and personal identities
and are thus more inclined to participate at work (Allan et al., 2019). Job characteristics
positively and significantly affect performance (Nugroho & Haryanto, 2019) by stimulating
psychological processes to engender an appreciation of the meaning of work and take
responsibility for feedback about work results that lead to greater intrinsic motivation and
improved job performance (Dong et al., 2020).
PMS and organizational commitment
Employees with a high level of PSM are more committed to their organizations and less likely
to leave, exhibit more organizational citizenship and proactive, and innovative behavior, are
more effective at reducing work-related stress and are more likely to demonstrate higher job
performance, according to (Chen et al., 2021). Job satisfaction, organizational commitment,
whistle blowing, citizenship behavior, and perceived internal efficiency are all positively
related to PSM (Asseburg & Homberg, 2020). Individuals with a PSM predisposition have a
variety of norm-based and emotive incentives, including a desire to serve the public interest
and a commitment to government in general (Caillier, 2020). Furthermore, those that follow
PSM have higher work satisfaction, organizational commitment, and organizational
citizenship behaviors (Miao et al., 2019; Parola et al., 2019; White et al., 2022; Wu et al.,
2019).
PSM is the antecedent of organizational commitment, implying that hiring people with
PSM can improve organizational commitment (Liu & Chen, 2021). On the other hand,
employees with a low degree of PSM have little internal incentive to design their employment
to benefit people and society, despite their bosses giving them a lot of autonomy and control
(Chen et al., 2021). In the same vein, it is found that employees who are driven to serve the
public good have higher job satisfaction, organizational commitment, performance, job
crafting, and organizational citizenship behaviors than those who are not (Parola et al., 2019).
A link between three organizational commitment components and four PSM aspects (policy-
making, public interest, compassion, and self-sacrifice) has been discovered by Park (2020).
PMS and job performance
When public employees have a sense of competence, self-determination, personal values that
are consistent with the demands of their work, and the belief that their work tasks impact
organizational outcomes, they are more likely to increase their work efforts (Lim et al., 2021).
High PSM employees are more likely to have higher job satisfaction and performance, are
more likely to report misconduct, are less likely to perceive that red tape is an issue, are less
likely to leave their job, and are more likely to be inventive employees (Bednarczuk, 2021).
PSM is positively connected with job performance within public organizations (Suhartini &
Nurlita, 2019), and public organizations with high numbers of workers with high PSM do not
need to rely on extrinsic motivations and practical incentives to manage people, according to
Stefurak, Morgan, and Johnson (2020).
PSM can potentially affect critical attitudinal and behavioral outcomes. Because
public servants can change their internal emotions and feelings by seeming honest to
consumers, those with high PSM likely to have better customer service performance
(Potipiroon et al., 2019). Employees with high PSM are more likely to work well when their
occupations allow them to live out their values of compassion, self-sacrifice, civic
responsibility, and policymaking (Gross et al., 2019). As previous research has demonstrated,
PSM may boost performance and public sector integrity (Meyer-Sahling et al., 2019). PSM
is an excellent indicator of performance. Employees motivated by public service perform
better and contribute to the achievement of organizational objectives because PSM inspires
them to be more engaged in public service and put more effort into their jobs (Lim et al.,
2021). It is found that prosocial motivation is an essential antecedent of outcomes such as job
satisfaction, intention to leave, effort, and performance (van der Voet & Steijn, 2021). They
do indicate that prosocial motivations can temporarily be simulated to achieve higher levels
of individual performance and effort. While the literature has provided mixed findings
concerning the PSM–job performance relationship, there is evidence that highly PSM
employees put in more work effort because they value public work with meaningful tasks
(Miao et al., 2019). Employees with a high PSM are enthusiastic about working in the public
sector and perform better (Holt, 2019; Liu & Chen, 2021; Sułkowski et al., 2020). PSM
demonstrates higher levels of organizational commitment, job satisfaction, and organizational
citizenship (Parola et al., 2019), and it emphasizes the prosocial motivation that underpins
public service motivated behavior - to "do good."
Organizational commitment and job performance
Employees’ commitment is seen to be a major determinant of job performance (Marzec et al.,
2020). The committed employees respond swiftly to clients' requests, avoid complaints,
improve customer loyalty, and provide excellent service (Ruiz-Palomo et al., 2020). Strongly
committed government servants are expected to stay in their jobs longer, have high job
satisfaction, and provide high-quality work and performance (Park, 2020). Employees with
high organizational commitment are more likely to perform on behalf of their company even
when the resources required to do their duties are lacking (Park, 2020). Job satisfaction and
organizational commitment are regarded to be work attitudes that reflect important workplace
outcomes and contribute to employee performance optimism (Qureshi et al., 2019). Because
of enhanced performance, organizations with more substantial organizational commitment
have higher work satisfaction, higher productivity, and lower turnover rates (Eliyana et al.,
2019; Qureshi et al., 2019).
It is found that value commitment, effort commitment, and retention commitment are
three hidden aspects of normative commitment (Donkor & Zhou, 2020). Affective
commitment is based on emotional relationships with the organization (Masud et al., 2018),
whereas continuation commitment is based on workers' decisions to stay with the company
because of the consequences of quitting. When affective commitment is more than normative
commitment and continuance commitment, job performance is better than vice versa; between
normative commitment and continuance commitment, job performance should be higher
when normative commitment is more remarkable than continuance commitment (Sungu et
al., 2020).
Based on the above literature review, we propose the following hypotheses (as presented in
Figure 1):
H1: Empowerment has a positive relationship with job characteristics.
H2: Job characteristics have a positive relationship with public service motivation.
H3: Empowerment has a positive relationship with public service motivation.
H4: Job characteristics have a positive relationship with job performance.
H5: Public service motivation has a positive relationship with job performance.
H6: Public service motivation has a positive relationship with organizational commitment.
H7: Organizational commitment has a positive relationship with job performance.
3. METHODOLOGY
Data collection
The study was carried out in the local government, using questionnaires reflecting the five
aspects, and public servants in Ho Chi Minh City were asked to fill out the surveys. Despite
the fact that Covid-19 was difficult to collect data on, the survey received 499 answers due to
our best effort. The sampling period was divided into two parts, with 42 samples collected for
pilot testing and 499 collected for official data collection and analysis.
The pilot test was the initial stage of data collecting. The sample size was 42, and the
questionnaires were evaluated to assure high validity before the official survey. The data for
the pilot test was collected exclusively on an internet platform using a Google form on
December 1, 2019. The official data collection began after completing the pilot test. The
authors hoped to acquire a better valid response rate through a face-to-face survey approach.
However, because of the COVID 19 issue, the authors decided to send both online and paper-
based surveys from February 2020 to May 2021. A total of 700 forms were distributed.
Finally, 499 correspondents participated in this study.
Of all the respondents, males account for 58 percent, while females account for 42
percent. 269 public servants (54 percent) hold a bachelor's degree, while 230 have completed
a graduate degree (46 percent). According to the statistics gathered, official positions account
for 92.4 percent of all jobs in public organizations. Table 1 below depicts the demographic
characteristics of the target respondents.
Measure
All of the measurement items of this paper were adopted from prior studies. First, we adopted
four items to measure empowerment, such as “My manager gives me the information I need
to do my work well” (EM1); “. My manager encourages me to use my talents” (EM2); “My
manager helps me to further develop myself” (EM3); “My manager encourages his/her staff
to come up with new ideas” (EM4) (van Dierendonck & Nuijten, 2011).
Second, we adopted the assessment of public service motivation, such as
“Meaningful public service is very important to me” (PSM1); “Seeing people get benefits
from the public programme I have been deeply involved in brings me a great deal of
satisfaction” (PSM2); “I would prefer seeing public servants do what is best for the whole
community even if it harmed my interests” (PSM3); “It is difficult for me to contain my
feelings when I see people in distress” (PSM4); “I am prepared to make enormous sacrifices
for the good of society” (PSM5) (Battaglio & Gelgec, 2017; Coursey & Pandey, 2007).
Third, we adopted five items to reflect the variable of job characteristics. They
included: “My job allows me to perform a variety of tasks that require a wide range of
knowledge, skills, and abilities?” (JC1); “My job allows me to complete a single piece of
work (rather than bits and pieces) from beginning to end” (JC2); “My job has a significant
positive impact on others, either within the organization or the public in general” (JC3); and
“I receive information about my job performance and the effectiveness of my efforts, either
directly from the work itself or from others” (JC4) (Battaglio & Gelgec, 2017).
Fourth, we adopted four items to measure the variable of organizational commitment.
They included: “Being a member of this organization is very captivating.” (COM1); “This
organization has a great deal of personal meaning for me” (COM2); “Too much of my life
would be disrupted if I decided I wanted to leave my organization now” (COM3); and “This
organization deserves my loyalty” (COM4) (Allen & Meyer, 1990; Battistelli et al., 2019).
Finally, the variable of job performance was adopted and included: “I adequately
complete assigned duties” (JP1); “I meet formal performance requirements of the job” (JP2);
“I can make constructive suggestions to the overall functioning of my work group” (JP3); and
“I encourage others to try new and more effective ways of doing their jobs” (JP4) (Talukder
et al., 2018).
All measures were translated into Vietnamese to receive further recommendations
from the group discussion to reflect the Vietnamese context and culture in a government
organization. All items were graded on a five-point Likert scale, with “1” indicating
strongly disagree and “5” indicating strongly agree. Furthermore, the survey was done in
Vietnamese, allowing respondents to comprehend and fill out their comments with ease
completely. The English version of the questionnaire was adapted before being translated into
Vietnamese.
Methodology
The hypotheses were tested using Structural Equation Modeling (SEM). SEM is a statistical
method for examining cause-and-effect relationships involving multiple equations. Partial
Least Square Structural Equation Modelling (PLS-SEM) is suitable for assessing a
complicated model with several concurrent relationships. The PLS-SEM is being extensively
developed in business research, marketing, economic management, and many other social
sciences. Furthermore, this study mainly targets predicting employees’ job performance
affected by PSM, job characteristics, organizational commitment, and empowerment. Also,
this is an appropriate condition for applying PLS-SEM as an SEM prediction method. PLS-
SEM is a suitable choice given the complexity of the model and the scarcity of well-
established literature (Gefen et al., 2000; Peng & Lai, 2012). Furthermore, since certain social
science research lacks distributional assumptions, using PLS-SEM is clearly advantageous
(Hair et al., 2019).
Data analysis
Reliability and validity
Various tests are used to examine the structural analysis. First, Cronbach’s alpha of each
construct is evaluated, and the results are all higher than 0.7, assuring the construct’s
reliability. Then all of the composite reliability of the factors are also above 0.7, which
indicates a high internal consistency (Bagozzi, 1981; Gefen et al., 2000; Hair et al., 2010)
The Average Variance Extracted (AVE) must be greater than 0.5 for convergent
validity, which determines if the latent components are effectively represented by their
observed variables. As one can see in Table 2, all AVEs are above the threshold, ensuring the
convergent validity (Fornell & Larcker, 1981; Hair et al., 2010) and indicating that each
construct explains 50 percent or more of the variance of the items that constitute the construct.
Furthermore, for outer loadings, all variables have outer loadings higher than 0.7, meeting the
theoretical requirement (Henseler, Ringle, & Sarstedt, 2012) and strengthening the scale's
reliability.
The statistical difference between the two constructs is tested for discriminant validity
by evaluating at cross-loadings. According to Hair et al. (2014), All components within a
construct should have greater outer loadings than cross-loadings with another construct. All
cross-loadings values meet the conditions for this criterion. As a result, the square root of
the AVE of a factor must be greater than the highest correlation coefficient of the factor with
other factors, according to the Fornell-Larcker requirement, or the AVE must be greater than
the square of the highest coefficient correlation (Fornell & Larcker, 1981; Hair et al., 2010).
In the results from Table 3, all indicators satisfy this criterion. Heterotrait-Monotrait ratios
(HTMT) were also used to assess discriminant validity, the mean value of all item correlations
across constructs compared to the mean of the average correlations for items measuring the
same construct. It is advised that data be compared to a 0.85 threshold using the HTMT as a
criterion (Clark & Watson, 1995; Kline & Rex, 2011). If the HTMT value is greater than this
threshold, there is a lack of discriminant validity. The discriminant validity of this model is
well-confirmed as all the indicators are less than 0.85 (Table 4).

Discussion
First, this paper reveals that there is a direct impact of empowerment on public service
motivation and job characteristics, which are in line with previous studies (Gao & Jiang, 2019;
Lin et al., 2019; Liu & Chen, 2021; Wang & Yang, 2021). Empowering leadership may
improve job characteristics, encouraging people to stay longer in their jobs and their
organizations. In this line, empowering initiatives balance bureaucratic restraints with
increased job meaning, allowing people to work confidently and efficiently. The findings
show that subordinates consider empowering leadership in terms of intrinsic motivation,
encouragement, and good treatment. When subordinates believe that organizations are their
own, they engage in the organization's service-oriented behaviors. Overall, these results could
be correct for any public sector organization worldwide.
4. CONCLUSION
This study enriches knowledge on public service motivation and its role in enhancing job
performance. Administrative reform can help government agencies increase civil employees'
PSM, boosting public services and organizational commitment. Furthermore, since
empowering leadership favors public organizations, organizations should provide
empowerment training and encourage managers to apply it. Autonomy, fair treatment,
cooperative decision-making, and leading by example should all be part of the training.
According to the current research findings, PSM is an antecedent of organizational
commitment. Organizational commitment will rise if civil servants strengthen their appeal to
public interest commitment. As we all know, transformational leadership, humanity
management, decision-making participation, empowerment, and delegation may all help
public employees increase their organizational commitment and, as a result, their work
performance. Although this study attempted to investigate the public sector organizations in
an emerging market characterized by collectivism, high level of bureaucracy and distance, the
findings have provided strong evidence to support the research hypotheses developed from
previous studies. Therefore, the managerial implications and recommendations could be
applied to any public sector organization.
Limitations and Future Research Directions
Despite the possibility of common method bias caused by self-reports, the statistical and
methodological safeguards used in the current investigation provide reassurance that all
variables exhibited discriminant validity. Because this study is based on cross-sectional data,
it may only be valid for a limited time span. As a result, academics and researchers should
perform longitudinal studies to track changes in behavior over time. Moreover, we just use
one-dimension measurement of the PSM established in developed nations was employed and
modified in this study, aiming for a tight focus. Future studies should consider including other
dimensions to integrate national contextual circumstances in the research design to investigate
the impact of cross-national variations behind the development of social support and
unfavorable workplace behaviors.
