Introduction

Over the last decade, mobile health (mHealth) applications have emerged as transformative tools in modern healthcare systems, revolutionizing the way individuals access and manage their health. mHealth refers to the use of mobile devices, such as smartphones and tablets, along with software applications (apps), to support medical and public health practices. These apps can provide a wide range of services, including health education, remote monitoring, medication reminders, appointment scheduling, and telemedicine consultations. By leveraging wireless communication technologies, mHealth bridges gaps in healthcare accessibility, particularly in underserved or remote areas, and empowers patients to take an active role in managing their health. Despite these advancements, challenges remain in ensuring that these digital solutions are user-friendly, culturally appropriate, and tailored to diverse populations.^1,2 For instance, while diabetes-focused apps have demonstrated measurable improvements in glycemic control and overall quality of life,^3,4 ongoing refinement is essential due to evolving technology and changing user expectations. Research highlights that usability, credible content, and opportunities for user feedback are critical factors influencing the successful adoption and clinical impact of mHealth apps.^5,6

The influence of specific demographic factors on user perceptions and engagement with mHealth apps remains only partially understood. While age, gender, and usage frequency are widely acknowledged as critical determinants of user satisfaction, there is limited understanding of how factors like marital status, employment status, and regional characteristics affect the effectiveness of these applications.^7,8 The distinct cultural and social environment of Hail City, Saudi Arabia, provides an ideal setting to investigate how local dynamics influence the acceptance and utilization of mHealth tools. Bridging these gaps is essential for developing digital health solutions that are more personalized and effective in addressing the diverse needs of users.^9,10 For example, studies have shown that women tend to be more proactive in seeking health information and utilizing health technologies compared to men.^11,12 Similarly, older adults may face challenges in adopting mHealth apps due to unfamiliarity with digital tools or concerns about privacy.¹³ Understanding these nuances can help developers design apps that cater to the unique preferences and requirements of different demographic groups.

The Sehhaty app, a comprehensive healthcare platform tailored for residents of Hail City, offers functionalities such as appointment scheduling, medication reminders, telemedicine consultations, and access to health-related information. Previous assessments indicate high user satisfaction, emphasizing its ease of use and ability to meet user requirements.¹⁴ This study evaluates user satisfaction and perceived utility of the app, focusing on demographic variables and user feedback that shape engagement. For instance, 65% of users rely on the app for online appointments, while 40% use it for telemedicine consultations.¹⁵ These statistics highlight the app's widespread adoption and utility in facilitating remote healthcare access. Additionally, the app has been praised for its intuitive interface and well-organized information, which contribute significantly to user comfort and satisfaction. However, some participants noted that while the app facilitates communication with healthcare providers, it could still improve in terms of interactivity.^16,17 Addressing this feedback can further enhance user satisfaction and engagement.

The selection of the health belief model (HBM), theory of planned behavior (TPB), social cognitive theory (SCT), technology acceptance model (TAM), and self-determination theory (SDT) was informed by a systematic review of existing literature on user engagement in digital health applications. HBM was chosen because it emphasizes perceived susceptibility, severity, benefits, and barriers, which are critical factors influencing users’ decisions to adopt mHealth tools.¹⁸ TPB highlights the role of attitudes, subjective norms, and perceived behavioral control in shaping user intentions, making it particularly relevant for understanding engagement behaviors.¹⁹ SCT provides insights into observational learning, self-efficacy, and reinforcement, which are essential for sustained app usage.²⁰ TAM focuses on perceived ease of use and perceived usefulness, two key determinants of technology acceptance identified in prior studies.²¹ Finally, SDT underscores the importance of autonomy, competence, and relatedness in fostering intrinsic motivation, which is crucial for long-term user engagement.²² Together, these theories provide a comprehensive foundation for understanding the psychological, social, and technological dimensions of user engagement in mHealth applications

This research also introduces the Integrated Digital Health Engagement Model (IDHEM), a novel framework integrating psychological, social, and technological dimensions to understand user behavior in digital health contexts. Understanding user satisfaction and perceived utility is crucial because these factors directly influence how users interact with mHealth applications and whether they continue to use them over time. For instance, if users find an app easy to navigate (ease of use) and perceive it as beneficial for managing their health (perceived utility), they are more likely to engage with the app consistently. These insights lay the groundwork for developing mHealth solutions that are not only functional but also tailored to meet the diverse needs of different user groups. Drawing on theories like the HBM, TPB, SCT, TAM, and SDT, IDHEM aims to guide the development of personalized mHealth solutions.^23,24 Specifically, data on how users perceive the app's usability, content organization, and overall value will help refine the components of IDHEM, ensuring that it addresses real-world challenges faced by diverse populations. For example, if the study reveals that older adults struggle with certain app features due to complexity, IDHEM can incorporate strategies to simplify interfaces for this demographic. Similarly, if gender differences emerge in terms of perceived usefulness, IDHEM can guide the development of gender-sensitive interventions. Ultimately, this research emphasizes the importance of continuously assessing and refining digital health tools to ensure their relevance and effectiveness in contemporary healthcare systems.

Structural equation modeling analysis

To investigate the intricate relationships between variables, we utilized SEM, a powerful statistical method that enables the simultaneous analysis of multiple relationships among latent constructs. The SEM model incorporated four key latent constructs: Ease of Use, System Information Arrangement, Perceived Usefulness, and User Satisfaction. These constructs were hypothesized to influence one another in a structured way, as depicted in the path diagram shown in Figure 2. This diagram visually illustrates the hypothesized relationships, demonstrating how each construct directly or indirectly affects User Satisfaction, which is the primary variable of interest.

Figure 2.

Path diagram of the SEM model. SEM: structural equation modeling.

The model showed an excellent fit to the data, supported by the following fit indices: CFI = 0.96, TLI = 0.95, RMSEA = 0.04, and SRMR = 0.03. These values suggest that the model effectively captures the underlying relationships among the constructs. Specifically, CFI and TLI values above 0.90 indicate a good fit, while RMSEA and SRMR values below 0.05 reflect a close alignment between the hypothesized model and the observed data.

The IDHEM model shown in Figure 6 builds upon the findings of the PLS-SEM analysis presented in Figure 2. The SEM results revealed significant relationships between Ease of Use, System Information Arrangement, Perceived Usefulness, and User Satisfaction, highlighting the importance of these constructs in shaping user engagement. For instance, Perceived Usefulness had the strongest total effect on User Satisfaction (β = 0.52, p < 0.001), underscoring its critical role in driving engagement. Similarly, Ease of Use (β = 0.45, p < 0.001) and System Information Arrangement (β = 0.38, p < 0.001) were found to significantly influence satisfaction, emphasizing the need for intuitive design and well-organized information. These findings align with the theoretical underpinnings of HBM, TPB, SCT, TAM, and SDT, which collectively inform the IDHEM framework. Specifically, the SEM model provided empirical support for integrating these theories into a unified framework that captures the complex interplay between psychological, social, and technological factors. IDHEM extends this analysis by incorporating demographic insights and offering practical guidance for tailoring mHealth applications to diverse user populations.

Second, System Information Arrangement also significantly influenced User Satisfaction (β = 0.38, p < 0.001), emphasizing the importance of having well-organized and accessible information within the app to enhance user experience. Lastly, Perceived Usefulness demonstrated the strongest total effect on User Satisfaction (β = 0.52, p < 0.001), highlighting its pivotal role in driving user engagement and satisfaction. This suggests that users who perceive the app as beneficial for managing their health are more likely to be satisfied with its overall functionality and performance. Taken together, these results underscore the interplay of usability, system design, and perceived value in shaping user satisfaction with mobile health applications.

Female	4.70 (0.50)	4.65 (0.55)	4.60 (0.60)

Correlation analysis

A Pearson correlation analysis was performed to examine the relationships between demographic factors and key variables, including Ease of Use, User Satisfaction, and Perceived Usefulness. The findings, outlined in Table 3, illustrate the strength and significance of these associations. For example, age exhibited weak correlations with Ease of Use (r = -0.035, p = 0.519), User Satisfaction (r = 0.033, p = 0.543), and Perceived Usefulness (r = 0.071, p = 0.194), indicating that age has minimal to no impact on these variables. Conversely, gender showed small but statistically significant negative correlations with all three variables: Ease of Use (r = -0.12, p = 0.035), User Satisfaction (r = -0.10, p = 0.045), and Perceived Usefulness (r = -0.15, p = 0.020). These results suggest that gender may influence user perceptions, with female participants generally reporting higher scores compared to their male counterparts. To visually represent these relationships, Figure 4 provides a heatmap of the correlation coefficients. The heatmap employs color gradients to emphasize the strength and direction of the correlations, facilitating the identification of patterns and enabling easier interpretation of the data. Overall, these findings highlight the importance of accounting for demographic factors when evaluating user experiences with mobile health applications, as they can significantly affect perceptions of usability, satisfaction, and utility.

ANOVA and independent samples t-test

To examine the impact of demographic factors on user perceptions of the Sehhaty app, ANOVA and independent samples t-tests were performed to compare group differences across key variables such as Ease of Use, User Satisfaction, and Perceived Usefulness. The results, summarized in Table 4, reveal significant differences based on demographic characteristics. For instance, marital status showed a notable impact on User Satisfaction (F = 4.179, p = 0.006), indicating that individuals with different marital statuses reported varying levels of satisfaction with the app. Similarly, employment status had a highly significant influence on all three variables, with p-values of 0.000 for Ease of Use, User Satisfaction, and Perceived Usefulness. This suggests that employed and non-employed users differ significantly in their perceptions of the app's usability, satisfaction, and overall utility. These findings are further illustrated in Figure 5, which presents bar charts comparing mean scores across demographic groups. The visual representation highlights the magnitude of these differences, emphasizing the importance of considering demographic factors when designing and optimizing mHealth applications to better meet diverse user needs. Collectively, these results underscore the role of individual characteristics, such as marital and employment status, in shaping user engagement and satisfaction with digital health tools.

These findings are consistent with earlier studies that emphasize the importance of usability as a key element in the acceptance and utilization of mHealth applications.^25–28 The intuitive interface and well-organized information contributed significantly to user comfort and satisfaction. Furthermore, users found the app efficient in terms of time required for use, suggesting that it fits seamlessly into their daily routines. These findings underscore the importance of prioritizing user experience in the design of mHealth apps to enhance adoption and sustained engagement.^29,30

The majority of users (88.64%) expressed satisfaction with the app's system information arrangement, indicating it was user-friendly and efficient. Participants appreciated features such as error recovery, consistent navigation, and comprehensive functionality, which are consistent with prior studies emphasizing the importance of robust design in enhancing user experience.^31,32 Moreover, most users (88.38%) found the app highly useful for their health and well-being, improving access to healthcare services and aiding in health management. These results align with studies showing that mHealth apps can significantly improve patient engagement and healthcare outcomes.^33,34 However, some participants noted that while the app facilitated communication with healthcare providers, it could still improve in terms of interactivity.^35,36 Addressing this feedback could further enhance user satisfaction and engagement.

Correlation analysis revealed significant relationships between demographic factors and user perceptions. Notably, age positively correlated with both system information arrangement and perceived usefulness, indicating that older users found the app more beneficial and well-organized.^37,38 Gender also significantly impacted perceived usefulness, with females rating the app higher than males (p = 0.035). These findings align with previous research suggesting that women tend to be more proactive in seeking health information and utilizing health technologies.^39,40 Additionally, marital status, employment status, and frequency of app usage significantly influenced user satisfaction and perceived usefulness, underscoring the need for personalized approaches in app design.⁴¹

The study identified several barriers to frequent app use, including technical issues, lack of internet access, and unfamiliarity with digital tools.⁴² Privacy concerns also emerged as a potential deterrent, consistent with prior research highlighting the importance of robust data protection measures and transparent privacy policies.^43,44 Despite these challenges, regular users reported improved health management and better access to healthcare services, aligning with studies that emphasize the effectiveness of mHealth tools in promoting healthier behaviors and improving patient engagement.^45,46 Addressing these barriers through user education, technical support, and transparent privacy practices can significantly enhance the app's adoption and effectiveness.

This study makes several important theoretical contributions. First, it introduces the IDHEM, which integrates five established theories—HBM, TPB, SCT, TAM, and SDT—to provide a comprehensive framework for understanding user behavior in digital health contexts. This integration addresses a significant gap in the literature by capturing the interplay between psychological, social, and technological factors in a holistic manner. Second, the study highlights the importance of demographic factors in shaping user perceptions and interactions with mHealth apps, offering new insights into how these factors can be incorporated into theoretical models.^34,47 Finally, the findings extend prior research by demonstrating the critical role of Perceived Usefulness in driving User Satisfaction, thereby reinforcing the relevance of TAM in contemporary digital health contexts.

From a managerial perspective, the findings of this study offer valuable guidance for the design and optimization of mHealth applications. First, the results underscore the importance of prioritizing usability and perceived usefulness in app development, as these factors have the strongest impact on user satisfaction. Developers should focus on creating intuitive interfaces and providing features that users perceive as beneficial for managing their health. Second, the study highlights the need for personalized approaches to app design, particularly in addressing the unique needs of different demographic groups.^33,48 For example, interactive features and culturally tailored content can enhance engagement among older adults and male users.^49,50 Third, the identification of barriers such as technical issues, lack of internet access, and privacy concerns provides actionable insights for improving app adoption and effectiveness. By addressing these challenges through user education, technical support, and transparent privacy practices, stakeholders can enhance the overall value and impact of mHealth solutions.

Introduction of the Integrated Digital Health Engagement Model

Findings suggest that tailoring mHealth apps to address demographic differences can enhance user engagement and satisfaction. For instance, incorporating interactive features, such as gamification and real-time feedback, can improve usability among older adults by addressing psychological motivators like autonomy and competence.³⁵ Similarly, personalized content, such as culturally tailored health recommendations or gender-specific messaging, has been shown to increase relevance and adoption among diverse populations.⁵¹ These insights are supported by prior studies indicating that interactive features enhance user motivation and sustained engagement,²⁵ while personalized content fosters a stronger emotional connection with the app.^52–54 The IDHEM (Figure 6) introduced in this study offers a novel approach by integrating elements from established health behavior theories and TAMs. IDHEM combines psychological, social, and technological factors, presenting a holistic framework to understand and enhance user engagement with digital health applications.^18,55,56 By incorporating theories such as the HBM, TPB, SCT, TAM, and SDT, IDHEM not only broadens the understanding of user behavior but also guides the development of more personalized, user-friendly, and effective digital health solutions.^25,35 This comprehensive framework ensures that health apps are not only accessible but also tailored to meet the unique needs and behaviors of diverse user populations

Limitations and future directions

Although this study offers significant insights, it is not without limitations. The cross-sectional approach prevents the establishment of causal relationships, and the reliance on convenience sampling may reduce the findings’ generalizability. To address these issues, future studies should adopt innovative approaches, such as using wearable technology to collect real-time behavioral data or conducting field experiments to test the effectiveness of new app features.⁵⁷ Additionally, the dependence on self-reported survey data may lead to response biases, which should be mitigated in future investigations through triangulation methods, such as combining surveys with interviews or observational studies.⁵⁸ The study was conducted in Hail City, which may have unique cultural and social dynamics influencing the findings. Exploring the applicability of IDHEM in different cultural and regional contexts can provide valuable insights into its scalability and adaptability. For example, cross-cultural studies could reveal whether features like gamification or personalized content have similar impacts in regions with varying levels of digital literacy.⁵⁹ Such investigations would enhance the model's flexibility and ensure its relevance across diverse populations.

Conclusion

The study evaluated user satisfaction and perceived usefulness of the Sehhaty app among residents of Hail City, Saudi Arabia, revealing high satisfaction levels with its ease of use, system information arrangement, and overall utility. These findings highlight the app's potential to enhance healthcare accessibility and management, particularly among younger users, females, and frequent users. Demographic factors such as marital status, employment status, and gender significantly influenced user perceptions, underscoring the need for personalized mHealth solutions. The introduction of the IDHEM provides a novel framework that integrates psychological, social, and technological dimensions to guide the development of more effective digital health tools. Despite these insights, the study has limitations, including its cross-sectional design, reliance on convenience sampling, and self-reported data, which may limit generalizability. Future research should address these gaps through longitudinal studies and randomized sampling to validate findings and explore IDHEM's applicability across diverse cultural contexts. Continuous updates to mHealth applications, informed by real-time feedback and technological advancements, are essential to maintaining relevance and effectiveness. By addressing barriers such as technical issues, privacy concerns, and user resistance, mHealth apps like Sehhaty can further enhance engagement and health outcomes.
