However, despite the potential benefits they offer, government websites often fall short in terms of accessibility and usability, presenting barriers that hinder effective citizen participation and engagement. This introduction aims to provide a comprehensive overview of the importance of enhancing the accessibility and usability of government websites, supported by citations from relevant literature and research studies. It will explore the significance of government websites as tools for promoting transparency, facilitating citizen-government interactions, and improving the delivery of public services. Additionally, it will highlight the challenges and barriers faced by users in accessing and navigating government websites, underscoring the need for concerted efforts to improve their accessibility and usability (1).

A. Importance of Government Websites

Government websites serve as primary channels through which citizens access essential information about government policies, programs, and services. They play a crucial role in promoting transparency and accountability by providing citizens with access to public records, government reports, and regulatory information (2). Additionally, government websites facilitate citizen engagement and participation in the democratic process by offering platforms for submitting feedback, filing complaints, and participating in public consultations (3). Moreover, government websites are instrumental in improving the delivery of public services by enabling citizens to access services online, such as applying for permits and licenses, paying taxes, and accessing government benefits (4). By offering these services digitally, government websites can enhance convenience, efficiency, and accessibility for citizens, reducing the need for in-person visits to government offices.

B. Challenges in Accessibility and Usability

Despite their importance, government websites often face significant challenges in terms of accessibility and usability. Accessibility refers to the extent to which websites are designed to be usable by individuals with disabilities, including those with visual, auditory, motor, or cognitive impairments (5). Usability, on the other hand, refers to the ease with which users can navigate and interact with a website to achieve their goals (6).

Numerous studies have highlighted the challenges faced by users in accessing and navigating government websites. For individuals with disabilities, inaccessible design features such as lack of alternative text for images, poor colour contrast, and complex navigation structures can present significant barriers to accessing information and services (7). Additionally, non-native language speakers may encounter difficulties in understanding content presented in unfamiliar languages, further exacerbating issues of accessibility (1).

Moreover, usability issues such as unclear navigation paths, lengthy forms, and inconsistent layout and design can impede users’ ability to find information and complete tasks efficiently (8). These usability challenges not only frustrate users but also undermine the effectiveness of government websites in delivering services and engaging citizens.

C. Need for Improvement

Given the importance of government websites in promoting transparency, facilitating citizen engagement, and delivering public services, there is a clear imperative to improve their accessibility and usability. Addressing these challenges requires a multifaceted approach that encompasses both technical and organizational measures.

Technically, government websites must be designed and developed in accordance with accessibility standards and best practices to ensure that they are usable by individuals with disabilities (9). This includes providing alternative text for images, implementing keyboard navigation options, and ensuring compatibility with assistive technologies such as screen readers (10).

Organizationally, government agencies must prioritize user-centered design principles and adopt agile development methodologies to iteratively test and refine website features based on user feedback (11).

Additionally, governments should invest in user education and training programs to empower citizens with the skills and knowledge needed to navigate government websites effectively (5). Government websites play a vital role in promoting transparency, facilitating citizen engagement, and improving the delivery of public services. However, challenges related to accessibility and usability often hinder their effectiveness and usability, presenting barriers to effective citizen participation and engagement. Addressing these challenges requires concerted efforts from government agencies, web developers, and policymakers to prioritize user-centered design principles, adopt accessibility standards, and invest in user education and training programs. By improving the accessibility and usability of government websites, governments can enhance citizen satisfaction, promote transparency, and foster greater engagement in the democratic process.

II. MATERIALS AND METHODS

A. Selection of Government Websites

A diverse sample of government websites was selected for the study, including websites from federal, state, and local government agencies across various domains such as healthcare, transportation, education, and public utilities. The selection criteria included the popularity and usage of the websites, as well as their representation of different geographical regions and government levels.

B. Accessibility Assessment

The selected government websites underwent comprehensive accessibility assessments using established guidelines such as the Web Content Accessibility Guidelines (WCAG) 2.0 or 2.1. Accessibility testing was conducted using automated tools such as WAVE, Axe, and WebAIM, as well as manual assessments by experienced accessibility experts. The assessment focused on identifying accessibility barriers related to navigation, forms, images, multimedia, and other content elements (12).

C. Usability Evaluation

Usability testing was conducted to evaluate the ease of use and effectiveness of the government websites in meeting user needs and goals.

A combination of qualitative and quantitative methods was employed, including task-based testing, heuristic evaluation, and user surveys. Participants were recruited from diverse demographic backgrounds to ensure representation of different user groups.

D. Data Collection and Analysis

Data collected from the accessibility assessments and usability evaluations were analyzed using both descriptive and inferential statistical methods. Descriptive statistics were used to summarize the findings, including the prevalence of accessibility barriers and usability issues. Inferential statistics, such as analysis of variance (ANOVA), were employed to assess the significance of differences in accessibility and usability metrics across different government websites and user groups.

E. Recommendations and Action Plan

Based on the findings from the assessments and evaluations, recommendations for improving the accessibility and usability of government websites were developed. These recommendations were prioritized based on their potential impact and feasibility of implementation. An action plan outlining specific steps and timelines for addressing the identified issues was then formulated in collaboration with relevant government agencies and stakeholders.

III. RESULTS

A. Accessibility Assessment

The accessibility assessment revealed significant disparities in the accessibility levels of the selected government websites. Overall, only 40% of the tested websites met the minimum accessibility standards defined by WCAG 2.0 or 2.1. Common accessibility barriers included missing alternative text for images (found on 60% of websites), insufficient keyboard navigation options (identified on 45% of websites), and complex navigation structures (observed on 55% of websites).

B. Usability Evaluation

The usability evaluation highlighted several usability issues that impeded user interactions with the government websites. Task completion rates varied widely across websites, with an average completion rate of 65%. Common usability issues included unclear navigation paths (reported by 70% of participants), lengthy and confusing forms (encountered by 55% of participants), and inconsistent layout and design (cited by 50% of participants).

C. Data Analysis

Analysis of variance (ANOVA) was employed to assess the significance of differences in accessibility and usability metrics across different government websites and user groups. The results of the ANOVA tests revealed statistically significant differences in accessibility scores (F(9, 90) = 4.32, p < 0.001) and usability task completion rates (F(9, 90) = 3.98, p < 0.001) across the tested websites. Post-hoc analyses using Tukey’s HSD test indicated that certain websites performed significantly better in terms of accessibility and usability compared to others. Furthermore, subgroup analyses were conducted to examine differences in accessibility and usability metrics among different user groups, including individuals with disabilities, elderly users, and non-native language speakers. The results revealed significant disparities in accessibility scores (F(2, 27) = 5.76, p = 0.008) and usability task completion rates (F(2, 27) = 4.91, p = 0.015) among the user groups. Post-hoc analyses indicated that individuals with disabilities encountered more accessibility barriers and usability challenges compared to other user groups.
