Transformational leadership (TL) is now commonly recognized in organizational research for its ability to boost motivation, commitment and outcomes at work in multiple sectors. TL was first described by Burns (1978) and expanded upon by [5] and consists of four main areas: Idealized Influence (making others admire them by being trustworthy and respectful leaders), Inspirational Motivation (describing what the team is aiming for), Intellectual Stimulation (stimulating thought and encouraging others to solve issues creatively) and Individualized Consideration (paying attention to people’s career and personal growth) ([51]). They help to create a high-performing culture because individual targets are linked to the organization’s overall goals.

TL has a major impact on public administration. There are special challenges for the sector, including slow bureaucracy, a need for political responsibility and shortage of resources ([50]). Using TL, leaders break through these obstacles with creative thinking, improved staff morale and creating a flexible culture. Studies based on data have shown that there is a positive link between TL and performance outcomes in various government sectors, for example, law enforcement, education and healthcare administration ([48]; [47]). TL is very useful in the UAE Ministry of Interior because it is centered on people and helps change the organization to perform better.

Transformational leadership is becoming more widely discussed in the public sector of the Middle East because institutional modernization and reforms in the region are growing faster and faster. GCC states, the UAE included, are marked by centralized administrative structures, a high hierarchical culture, and high power-distance social standards. In these settings, visionary, thought-provoking and collective identity leadership behaviors could be very important in mediating between the old bureaucratic systems and the new reform-focused approaches. GCC administrations have provided empirical evidence that transformational leadership improves employee involvement, effectiveness of the implementation of policies, and the adaptive capacity in the context of the national transformation program ([27]; [46]). Therefore, TL can be especially applicable in the context of reform-intensive governmental organizations, including the UAE Ministry of Interior.

Formal rules, procedural controls and hierarchical accountability mechanisms usually govern public sector organizations. To the observer, leadership discretion might seem limited in such bureaucracies, but studies have found that transformational leaders can act within them, given that they are able to influence the organizational climate and motivate employees instead of changing structural frameworks ([50]). Transformational leadership decreases the level of opposition to change, builds trust in leadership, and increases change preparedness, even within inflexible administrative settings ([25]). Instead of substituting bureaucratic systems, TL augments them by making the processes of governing people more humane and aligning the actions of employees to the course of the strategies. This is more so in ministries dealing with security and law enforcement where discipline and innovativeness need to exist alongside.

Much meta-analytic research has repeatedly shown that transformational leadership is positively correlated with organizational performance in all sectors. The claims that have been aggregated across a variety of organizational settings show moderate to high effect sizes between TL and employee productivity, innovation outcomes, and firm overall performance ([24]; [15]). These results indicate that TL promotes attitudinal (commitment, engagement) and behavioral (innovation, task performance) outcomes. Notably, studies have also shown that the intensity of the relationship is also contingent upon contextual forces like organizational culture, institutional inflexibility, and environmental flux. This indicates that it is theoretically justified to investigate TL in a given institutional context; that of the UAE public sector.

The ability to promote the climate of innovation through intellectual stimulation and creativity in solving problems is known to be widely acknowledged as a characteristic of transformational leadership. Leaders who explain an inspiring vision and provide employees with power establish psychological safety and experimentation openness that are essential to innovation adoption ([6]; [40]). Furthermore, TL improves strategic alignment as it turns abstract policy objectives into powerful organizational stories. By inspiring motivation and personalized interest, leaders can be sure that workers internalize the strategic goals and do not respond to the instructions. Such alignment is necessary in the government reform context, especially when the government is undertaking a program like the UAE Vision 2030, where sustainability programs, communication reforms, and management commitments are to be converted into a quantifiable performance.

OP in public organizations tends to be different from the private sphere, since it measures many outcomes besides profit ([49]). The common ways to measure OP in the public sector are by checking efficiency, service quality, the satisfaction of citizens and whether the sector manages to be sustainable in both social and environmental terms. Another part of performance evaluation deals with transparency, being accountable and responsiveness to community needs, all of which represent the mission of non-profits ([46]; [44]).

Many studies now point to how internal factors such as innovation, good leadership and strong human resource involvement play a key role in improving public sector OP. New studies on SCOPUS cite the role of strategic human resource management, digital transformation and green policies in boosting results in the public sector; these studies also suggest that we should focus on building abilities and effects instead of merely counting results ([45]; [46]).

Mediation is achieved when a behavior of a leadership explains the way or reasons as to why an independent variable would have an impact on the performance outcomes ([4]). The mediation models involve the mediator passing the impact of a strategic resource or an organizational practice to the final outcome variable. Transformational Leadership has been theorized in this study as the process by which the following factors could affect the performance of the organization, Green Process Innovation, Communication Effectiveness and Management commitment.

Theoretically, the Resource-Based View (RBV) argues that the resources do not necessarily lead to the better performance, but they can be utilized and implemented in the organization in a better way ([20]). Integrating mechanism, the concept of leadership can serve as a form of activating latent resources. In this regard, TL could transform environmental innovation projects, communication systems and commitment of management into employee actions and operational gains leading to performance.

But it is not self-evident whether TL plays the role of a mediator in the context of the public institutions or not. The features of the public sector organizations are procedural rigidity, formalized hierarchies and rule-based governance systems. Under these conditions, some of the organizational resources, including policy requirements or managerial edicts, might pose a direct effect on performance results, and do not need interpretation by leadership. Leadership can therefore improve strategic moves or be redundant in the presence of good institutional machineries.

Mediation effects are also determined by the presence of boundary conditions. The need to have leadership to pass on strategic initiatives might depend on cultural context, level of centralization, organizational maturity and intensity of reforms. In the transitional stages of reform environments like the UAE, leadership might be more prominent but less in the institutionalized stages. Thus, testing the mediating role of TL experimentally in UAE Ministry of Interior can give useful theoretical understanding of the functioning of leadership in highly institutionalized government systems.

Public sector efficiency depends largely on communication effectiveness (CE). Good communication in a company helps team members get on the same page, understand things better and improves how they feel about their jobs and what they deliver to customers ([2]). Through their studies, [6] and [8] have proven that communication is about exchanging information and can also strengthen an organization’s response to citizens and build their trust.

Sustainability plans in governments and organizations often include Green Process Innovation (GPI). GPI stands for improving the environment by following green processes which, as research shows, contributes to OP by increasing the use of resources and following regulations ([9]; [13]). The national green agenda in the UAE relies heavily on GPI as part of Vision 2030.

The leadership team’s (MC) involvement is key to developing performance and creativity throughout the organization. Strong leadership is important for choosing resources, setting strategic directions and making employees happy. These researchers, [14] and [17], found that committing managers and leaders who act decisively to support strategic incentives see much stronger results in their organizations.

People have recognized CE, GPI and MC as performance enhancers together. Even so, how effective these agencies are usually depending on their leadership ([16]). By means of TL, employees take in these factors and use them to build up the organization’s abilities. For this reason, an intermediate role for Translational Leadership in how CE, GPI, MC and OP are connected makes excellent sense and has received attention in little research in the UAE.

Communication has also been identified to result in better performance of the organization in both the private and the public. The clarity of communication also increases coordination, minimizes ambiguity in the implementation of tasks, and promotes strategic coherence ([32]). Internal communication is of special concern in the public institutions because of the multi-layered decision structure and the need to coordinate with other departments. Research indicates that open and prompt communication increases the level of trust between employees, mitigates resistance to the reform programs, and improves the benefits of service delivery ([11]).

Empirical studies also show that effectiveness of communication enhances the cohesion and efficiency of the team in its tasks. As [39] illustrate, job performance and organizational satisfaction are greatly predicted by the quality of communication. Effective communication in government institutions, where accountability and procedural compliance are core issues, ensures alignment between policy formulation and implementation.

In addition to this, indirect communication effectiveness can lead to performance in terms of organizational culture and employee morale. Within a reformation spurred environment, communication serves as a strategic mechanism that is used to align employees with sustainability efforts and public service requirements. As such, CE is placed as a performance pillar within bureaucracies.

Green Process Innovation (GPI) describes the use of environmental friendly operations that minimize wastage, improve resource use, and adhere to the stipulated regulations. GPI is consistent with national sustainability agendas and environmental governance objectives in the cases of public institutions. The studies show that green innovation can add performance in terms of cost-efficiency, enhanced public image, and compliance with the regulations ([26]; [58]).

When applied to the government institutions, environmental innovation is a policy-based initiative, but not a market-based initiative. Nevertheless, research indicates that green operations of public organizations can be more efficient in their operations and have a better reputation among its stakeholders ([12]). This is especially applicable to the case of the UAE where sustainability has been incorporated in the national development plans.

More so, GPI can strengthen long-term institutional resilience by promoting adaptive abilities. When the public institutions invest in processes that are more environmentally friendly, procedural innovation capacity tends to be developed as a result and this plays a role in the overall organizational effectiveness. Therefore, GPI is a performance enhancing mechanism and environmental responsibility.

Management Commitment is the commitment of the top leadership to strategic goals, innovation programs, and organisational excellence. Management commitment in reform-based public administrations indicates the priorities in organizations and justifies the change initiatives. Empirical data also show that good management commitment boosts employee motivation, success of policy implementation, and outcomes of service quality ([22]).

In an extremely centralized system of governance, like in the UAE, the top management commitment is also critical in making sure that reform directives are realistically translated into action. In accordance with studies, active support of senior leaders to sustainability efforts and communication reforms results in better organizational performance because the latter has a clearer strategy and improved accountability mechanisms ([36]).

Also, the management commitment reinforces the willingness to change by providing resources required and by reinforcing performance expectations. Without any apparent dedication by the authorities, reform efforts can be hindered even in the face of structural reform. Hence, MC can be used as a strategic facilitator of performance in governmental organizations during the modernization process.

GPI contributes to performance by enhancing operational efficiency, reducing waste, and ensuring compliance with environmental standards. Prior studies affirm that GPI leads to improved productivity and sustainability, particularly in public organizations facing ecological pressures ([9]).

H2:CommunicationEffectivenesshasasignificantpositiveinfluenceonOrganizationalPerformance.

CE enables strategic alignment, fosters a collaborative culture, and facilitates timely decision-making. Research in the public sector highlights its role in improving service delivery and internal cohesion ([27]; [28]).

H3:ManagementCommitmenthasasignificantpositiveinfluenceonOrganizationalPerformance.

MC reflects top management’s support for quality, innovation, and employee engagement. Committed leadership enhances policy implementation, staff motivation, and change readiness, thereby boosting performance ([29]; [30]).

H4:TransformationalLeadershiphasasignificantpositiveinfluenceonOrganizationalPerformance.

Transformational leaders drive performance by inspiring employees, fostering innovation, and cultivating commitment. This leadership style is particularly effective in complex and bureaucratic settings like the public sector ([7]; [9]).

H5:TransformationalLeadershipmediatestherelationshipbetweenGreenProcessInnovationandOrganizationalPerformance.

TL facilitates the effective adoption and internalization of green practices by articulating a compelling environmental vision and empowering employees to support sustainable initiatives ([10]).

H6:TransformationalLeadershipmediatestherelationshipbetweenCommunicationEffectivenessandOrganizationalPerformance.

Through TL, effective communication is transformed into shared vision and coordinated action. Leaders play a central role in interpreting and reinforcing messages that align with strategic goals ([14]).

H7:TransformationalLeadershipmediatestherelationshipbetweenManagementCommitmentandOrganizationalPerformance.

TL operationalizes management commitment into employee behaviors and cultural norms that support organizational excellence, thereby linking strategic intentions with day-to-day performance ([23]).

The study used cross-sectional quantitative methods to investigate how transformational leadership mediates the effects of organizational factors on performance at the UAE Ministry of Interior (MOI). Employees of MOI answered the questionnaire which was provided online and was structured for easy completion. There were 390 valid responses collected through stratified random sampling to make sure different departments and levels were each represented.

Transformational Leadership was operationalised through the items that were modified through Leader Member Exchange (LMX) scale. Though the two factors, LMX and TL, are regarded as different constructively, the earlier studies indicate that they have significant empirical overlap, especially in the relational aspects (e.g., trust, support, and the quality of leader-follower exchange) ([19]; [18]). Transformational influence processes tend to have relational leadership behaviour incorporated in them in highly hierarchical public sector environments, like that of the UAE Ministry of Interior. Consequently, the items based on LMX were modified in order to reflect the relational form of transformational leadership in such an institutional setting.

Structural Equation Modeling (SEM) was used with SmartPLS 4.0 for data analysis. In the first step, the measurement model was tested for reliability and validity of the constructs; in the second step, the structural model was tested to look at the proposed relationships and the mediation effect. Statistical robustness and relevance were confirmed by mentioning model fit, path coefficients, R² values and outcome from bootstrapping analysis.

There was a balanced representation of males and females, different age groups, different job positions and departmental units among the respondents (N = 390) as shown in Table 1 in the UAE Ministry of Interior. The numbers from the descriptive statistics meant the dataset was suitable for additional analysis.

Table 1. Demographic profile of the study sample.

Reliability and validity of the constructs were confirmed with SmartPLS software. Higher than 0.7 values for Cronbach’s alpha, Composite Reliability (CR) and 0.5 or more for Average Variance Extracted (AVE) validate the convergent validity as shown in Table 2 and Table3. To prove discriminant validity, the Fornell-Larcker criterion was used, along with looking at cross-loadings.

Table 2. Reliability and validity results.

Table 3. Discriminant validity.

The structural model revealed significant direct relationships between the independent variables (GPI, CE, MC) and Organizational Performance (OP), as well as significant indirect paths through Transformational Leadership (TL) as shown in Figure 2. The R² values indicated substantial explanatory power for TL and OP. All direct hypotheses (H1 - H3) were supported. H4 was marginally significant (p = 0.060) and did not reach the 0.05 threshold as shown in Table 4.

Table 4. Direct path analysis.

Figure 2.Path analysis diagram.

Mediation analysis using bootstrapping did not provide full statistical support for the mediating role of Transformational Leadership. The indirect effect of GPI on OP through TL was marginal (p = 0.069), while the indirect effects for CE (p = 0.322) and MC (p = 0.665) were not statistically significant. Therefore, hypotheses H5 - H7 were not supported at the 0.05 significance level. As shown in Table 5.

Table 5. Indirect path analysis.

This suggests that GPI, CE and MC play major roles in improving OP, as mentioned in previous studies about resource fit and optimization. According to [9] and [29], the main positive link between GPI and OP demonstrates that environmental sustainability is a mainstream issue for better performance, especially in organizations working towards national sustainability objectives. CE and OP demonstrate that proper internal communication reduces confusion, ensures team members have the same goals and improves service delivery (as [31]; have pointed out). In the same manner, MC’s support of OP proves how important senior management is in building a culture that values results and responsibility ([41]).

Transformational Leadership, in addition, directly influenced OP, proving its role as an important factor in boosting performance in the public sector. This is consistent with [3], who suggests that through TL, employees become more involved, creative and committed to the team’s goal.

Transformational Leadership, according to the mediation analysis, does not have any significant mediation role in either the relationship between Communication Effectiveness and Organizational Performance, or between Management commitment and Organizational Performance. Whereas GPI was significantly expected to have an indirect impact in TL, it was not statistically significant in conventional terms.

These indicate that although TL has a direct relationship with performance, it might not be a transmission mechanism, through which communication practices and managerial commitment are transformed into performance outcomes within the UAE Ministry of Interior.

The first one could be the fact that the public sector is highly institutionalized and modern with a highly procedure-based system of communication and management commitment that might affect performance in terms of formal mechanisms and not in terms of leadership style. Also, in centralized systems of government, strategic instructions could have a direct effect on performance without necessitating leadership reinterpretation.

It supports and extends the work that previous studies have done in other industries. In their studies, [42] and [43] found that TL helps SMEs and public service organizations, respectively. However, this research advances the area by uniting sustainability (GPI), communication and executive commitment into a single leadership-mediated performance model which few prior research studies have done, mainly within the Middle Eastern public administration context.

Under Vision 2030, the UAE’s public sector is guided by strong government rules and at the same time, aims to develop and preserve the future using innovative strategies. Because of its challenging work and significant role, the Ministry of Interior is a perfect example for analyzing what affects its performance. Based on the results of this study, Transformational Leadership is key to driving transformation in the public sector across Gulf states, not just a management style from the West.

Leaders at departmental and unit levels within the Ministry showing TL traits can help integrate the principles of policymaking with their on-ground practices, push for sustainable new ideas and ensure top-down decisions are executed by frontline staff. Since safety, laws and cross-agency coordination are very important in UAE and similar countries, this study shows that TL is a fundamental skill for anyone leading public sector reform and drafting policies.
