Literature review
The Unified Theory of Acceptance and Use of Technology (UTAUT) model has been extensively applied in the analysis of mobile healthcare applications to understand user behavior and adoption trends.When examining mobile health apps through the lens of the UTAUT model, researchers investigate how factors such as Performance Expectancy (PE), Effort Expectancy (EE), Social Influence (SI), and Facilitating Conditions (FC) influence users' intentions to use and continue using these applications (1).
The adoption and sustained use of mobile medical applications have become essential facets of modern healthcare, particularly highlighted during health crises such as the COVID-19 pandemic.Several studies provide insights into the factors influencing user engagement with these technologies, often grounding their findings in established behavioral frameworks.This literature review synthesizes relevant research that informs the understanding of user behaviors regarding mobile health applications, focusing on key dimensions such as trust, performance expectancy, social influence, and facilitating conditions.
Celsi and Olson (2) emphasize the role of consumer involvement in attention and comprehension processes, noting that a heightened sense of involvement leads to improved engagement and understanding of health-related information.This idea resonates with the findings of Rai et al. (3), who explore the determinants of consumer mobile health usage intentions.Their research points out that high levels of user involvement and trust in healthcare applications significantly enhance the likelihood of adoption and continued use.
Trust remains a crucial element in healthcare interactions, as highlighted by Harrison and McKnight (4), who provide a comprehensive typology of trust in e-commerce contexts.Their interdisciplinary approach underlines the multifaceted nature of trust and its impact on customer relationships, which is applicable in healthcare settings where patient trust can influence engagement with mobile medical applications.The study by Mayer et al. (5) further elucidates this point by presenting an integrative model of organizational trust, showcasing how mutual trust can foster stronger doctor-patient relationships-a critical factor emphasized in the current study's UTAUT model application.
Cho (6,7) investigates the adoption of smartphone health apps among college students and underscores the importance of postadoption beliefs on the continued use of these applications.Their findings align with the current study, which identifies performance expectancy as a significant determinant of user intention.Similarly, Dutta Bergman (8) finds a correlation between health orientation and satisfaction, which underscores the necessity for healthcare providers to foster effective communication to enhance user experience and satisfaction with mobile health resources.
The impact of social influence is another vital area discussed in the literature.Zhang et al. (9) utilize a modified theory of reasoned action model to understand gender differences in m-health adoption and underscore the effects of social norms on technology acceptance.The current study extends this discussion by revealing the moderating role of doctor-patient trust on social influence, particularly in the context of heightened trust during an epidemic, driven by positive media coverage and risk-sharing initiatives.
Facilitating conditions are also pivotal to technology acceptance.The DeLone and McLean Model (10) of information systems success highlights the importance of various external factors that can affect user satisfaction and system use.The work of Shin et al. (11) on IT service success conditions complements this perspective by examining the duality of success factors in technology adoption.These insights are particularly relevant for app developers and healthcare providers 10.3389/fpubh.2024.1414125Frontiers in Public Health 03 frontiersin.orgaiming to improve the usability and accessibility of mobile medical applications.In summary, the investigated literature provides a robust framework for understanding user intentions towards mobile medical applications, particularly during health crises.The studies reviewed affirm the importance of trust, performance expectancy, social influence, and facilitating conditions.As the landscape of healthcare continues to evolve with digital technologies, these elements will remain critical for fostering user engagement and improving health outcomes through mobile applications.The current study's findings contribute valuable insights to this ongoing dialogue, reinforcing the need for a focus on trust and user experience in digital health strategies.

Principal component analysis
The Table 3 illustrates the information extraction status of the principal components for the research items, as well as the corresponding relationships between the principal components and the research items.From the table, it can be observed that the communalities values for all research items are higher than 0.4, indicating a strong association between the research items and the principal components, enabling effective extraction of information.

Regression analysis
In the linear regression analysis conducted in this study, Performance Expectancy (PE), Effort Expectancy (EE), Social Influence (SI), and Facilitating Conditions (FC) were considered as independent variables, while Behavioral Intention (BI) was the dependent variable.The formulated model is represented as BI = 0.206 + 0.149*PE + 0.108*EE + 0.312*SI + 0.381*FC, with an R-square value of 0.786, indicating that PE, EE, SI, and FC collectively explain 78.6% of the variance in BI.The model successfully passed the F test (F = 193.786,p = 0.000 < 0.05), signifying that at least one of the independent variables significantly impacts BI.Despite the detection of multicollinearity (VIF value >5 but <10), suggestions for addressing collinearity include utilizing ridge regression or stepwise regression.It is recommended to further examine variables with close correlations and consider their removal for a refined analysis.Specifically, the regression coefficient for PE is 0.149 (t = 2.536, p = 0.012 < 0.05), indicating a significant positive influence on BI.For EE, the regression coefficient of 0.108 (t = 1.434, p = 0.153 > 0.05) suggests no significant impact on BI.Conversely, the coefficient for SI is 0.312 (t = 5.724, p = 0.000 < 0.01), implying a significant positive   4).
The linear regression analysis in this study was conducted with doctor-patient trust as the independent variable and Behavioral Intention (BI) as the dependent variable.The model is represented as: BI = 1.738 + 0.552* Doctor-patient trust, with an R-square value of 0.399, indicating that doctor-patient trust can account for 39.9% of the variation in BI.The model successfully passed the F-test (F = 141.899,p = 0.000 < 0.05), confirming that doctor-patient trust significantly influences BI.Further analysis revealed that the regression coefficient for doctor-patient trust is 0.552 (t = 11.912,p = 0.000 < 0.01), indicating a significant positive impact on BI.
In summary, the analysis underscores that doctor-patient trust plays a crucial role in shaping users' Behavioral Intention (BI), with a substantial positive influence.These findings highlight the importance of fostering trust in the doctor-patient relationship to enhance users' intentions towards utilizing mobile health management services (Table 5).
In the conducted linear regression analysis, the independent variable was the situational variable, while the dependent variable was doctor-patient trust.The model formula calculated was: Doctorpatient trust = 2.008 + 0.381 * situational variable.The R-square value of the model indicated to be 0.289, implying that situational variables can account for 28.9% of the variance in doctor-patient trust.The F-test conducted on the model demonstrated statistical significance (F = 86.851,p = 0.000 < 0.05), confirming that the situational variables significantly influence doctor-patient trust.
Further analysis revealed that the regression coefficient for the situational variables is 0.381 (t = 9.319, p = 0.000 < 0.01), signifying a significant positive impact on doctor-patient trust.
Overall, the summary analysis concludes that all situational variables have a significant positive effect on doctor-patient trust.These findings emphasize the substantial impact of situational factors on the development of trust in the doctor-patient relationship (Table 6).
In the conducted linear regression analysis, the independent variable was the situational variable, while the dependent variable was Behavioral Intention (BI).The model formula derived from the analysis is: BI = 2.884 + 0.199 * situational variable.The R-square value of the model, at 0.103, indicates that the situational variable can account for 10.3% of the variance in BI.Upon conducting the F-test on the model, statistical significance was observed (F = 24.667,p = 0.000 < 0.05), affirming that the situational variable indeed impacts BI.
Further analysis revealed that the regression coefficient for the situational variable is 0.199 (t = 4.967, p = 0.000 < 0.01), indicating a significant positive influence on BI.
Overall, the summary analysis underscores that all situational variables hold a significant positive impact on BI.These findings highlight the importance of situational factors in influencing individuals' Behavioral Intentions and emphasize the role of context in shaping decision-making processes (Table 7).

Adjustment effect analysis
The analysis of the adjustment effect is segmented into three models in this study.Model 1 incorporates the independent variable (SI), Model 2 introduces the moderating variable (doctor-patient trust) in addition to Model 1, and Model 3 further includes the interaction term (product term of the independent variable and the moderating variable) on top of Model 2.
In Model 1, the objective is to investigate the impact of the independent variable (SI) on the dependent variable (BI) without considering the influence of the moderating variable (doctor-patient trust).The results displayed in the table reveal that the independent variable (SI) exhibits statistical significance (t = 19.744,p = 0.000 < 0.05), indicating a substantial influence of SI on BI.
The examination of the moderating effect entails two approaches: evaluating the significance of the change in F-value from Model 2 to Model 3, and assessing the significance of the interaction terms in Model 3. In this instance, the moderating effect is analyzed utilizing the second approach.
The table data indicates that the interaction between SI and doctor-patient trust demonstrates statistical significance (t = −2.458,p = 0.015 < 0.05), signifying that when SI exerts an impact on BI, the moderating variable (doctor-patient trust) significantly influences the amplitude of the impact at different levels (Table 8).
The interaction terms of the other three independent variables PE, EE, FC and doctor-patient trust do not show significance, which means that when PE, EE, FC have an influence on BI, the influence amplitude of the regulating variable (doctor-patient trust) remains the same at different levels.

Ridge regression analysis
Ridge Regression analysis is used to address multicollinearity issues in linear regression analysis by introducing k identity matrix units to estimate regression coefficients.This may result in information loss, yet facilitate reasonable estimation of the regression model.
The process includes three main steps:     In the analysis, when PE, FC, SI, and EE are independent variables and Trust is the dependent variable, the ridge trace plot visually indicates the optimal K value.Users can leverage the recommended K value provided by SPSSAU, based on criteria including VIF < =10 and a preference for smaller K values, suggesting K = 0.02 (Figure 2).
From the Table 9, it can be observed that in the Ridge regression analysis, PE, FC, SI, and EE were used as independent variables, while BI was used as the dependent variable, with a K value of 0.020.The model's R-squared value of 0.786 indicates that PE, FC, SI, and EE can explain 78.59% of the variance in BI.The F-test results showed that the model passed the F-test (F = 193.647,p = 0.000 < 0.05), indicating that at least one of PE, FC, SI, or EE has a significant effect on BI.The model formula is represented as: BI = 0.228 + 0.064*PE + 0.374*FC + 0.309*SI + 0.197*EE.The regression coefficient for PE was 0.064 (t = 0.863, p = 0.389 > 0.05), indicating that PE does not have a significant effect on BI.The regression coefficient for FC was 0.374 (t = 8.778, p = 0.000 < 0.01), suggesting that FC has a significant positive influence on BI.Similarly, the regression coefficient for SI was 0.309 (t = 6.342, p = 0.000 < 0.01), signifying a significant positive effect on BI, while the coefficient for EE was 0.197 (t = 2.195, p = 0.029 < 0.05), indicating a significant positive impact of EE on BI.In conclusion, it can be inferred that FC, SI, and EE have significant positive effects on BI, while PE does not have a significant influence on BI.

Lasso regression analysis
From the Table 10, it can be observed that, using PE, FC, EE, and SI as independent variables and BI as the dependent variable for Lasso Regression analysis, the value of K is set at 0.010.The model's R-squared value is 0.748, indicating that PE, FC, EE, and SI can explain 74.76% of the variance in BI.Upon conducting an F-test for the model, it was found that the model passed the F-test (F = 156.229,p = 0.000 < 0.05), suggesting that at least one of PE, FC, EE, or SI has an impact on BI.The model equation is: BI = 0.956 + 0.000*PE + 0.299*FC + 0.199*EE + 0.241*SI.
The regression coefficient value for PE is 0.000 (t = 0.000, p = 1.000 > 0.05), indicating that PE does not have an impact on BI.The regression coefficient value for FC is 0.299 (t = 6.232, p = 0.000 < 0.01), indicating that FC has a significant positive impact on BI.The regression coefficient value for EE is 0.199 (t = 1.636, p = 0.103 > 0.05), indicating that EE does not have an impact on BI.The regression coefficient value for SI is 0.241 (t = 4.347, p = 0.000 < 0.01), indicating that SI has a significant positive impact on BI.In summary, the analysis suggests that FC and SI have a significant positive impact on BI, while PE and EE do not have an impact on BI.
Based on the linear regression analysis, PE, EE, SI, and FC collectively account for 78.6% of the variability in BI, with the model passing the F-test, indicating the presence of at least one significant predictor for BI.Notably, while PE shows a non-significant influence on BI, both SI and FC have significant positive effects.These findings underscore the pivotal roles of SI and FC in determining BI.
In the Ridge regression analysis, PE, FC, SI, and EE explain 78.59% of the variance in BI, with the model passing the F-test.FC, SI, and EE demonstrate significant positive impacts on BI, whereas PE shows no significant effect.This aligns with the linear regression results, emphasizing the influences of FC, SI, and EE on BI.Conversely, the Lasso regression analysis reveals that PE, FC, EE, and SI account for 74.76% of the variance in BI, with the model also passing the F-test.FC and SI exhibit significant positive effects on BI, while PE and EE do not show significant impacts.Though differing slightly from the linear and Ridge regression outcomes, the results reaffirm the significance of FC and SI in relation to BI.By comparing the results from the three distinct regression methods, a comprehensive understanding of the impact of each predictor variable on the dependent variable can be gained.This aids in identifying key factors influencing behavioral intentions and offers deeper insights into the research problem.Ultimately, integrating findings from multiple analysis methods can lead to more robust and insightful conclusions, enhancing the depth and foresight of the study.

Analysis of the impact of the epidemic on doctor-patient trust
During the COVID-19 epidemic, a significant shift in the doctor-patient relationship has been observed.News reports indicate that, unlike the conventional tense and disharmonious relationship, medical staff have treated patients as family members, and patients have viewed medical staff as benefactors.This unprecedented harmony has resulted in an ideal doctor-patient relationship characterized by intimacy, harmony, beauty, and ideal interactions.
In contrast to the prevalent lack of trust between doctors and patients in modern times, patients often harbor suspicions regarding excessive examinations, overmedication, unnecessary surgeries, poor technical skills, and questionable medical ethics.However, the major crisis presented by COVID-19 has fostered a shared sense of destiny between doctors and patients.Confronting a common threat, only by collaborating and fighting together can they overcome the epidemic.In hospitals, patients exhibit a high degree of trust in medical staff and recognize their dedicated service, leading to positive interactions between the two parties.
Additionally, compared to regular healthcare settings, where patient satisfaction tends to be relatively low, makeshift hospitals provide equal access to medical resources regardless of patients' status or social standing.This egalitarian approach contributes to patients' elevated sense of medical experience and satisfaction.
During the epidemic, medical workers have gained widespread attention and recognition from society.The media portrays their professional responsibilities and shares touching stories, positioning them as "national heroes." Within makeshift hospitals, the doctorpatient relationship has reverted to its original simplicity, with patients showing respect towards medical staff, and medical staff providing attentive care.By fulfilling their professional duties, medical workers not only achieve the goal of curing diseases and saving lives but also experience an enhanced sense of professional fulfillment.

Deep causes of doctor-patient trust 7.2.1 The doctor-patient trust crisis as a key driver of tension
In the current doctor-patient relationship, especially in large hospitals such as the well-known top three hospitals, overcrowding and long waiting times have become prevalent.Doctors face immense work pressure, and their medical service attitudes often fall short of expectations.Patients, during their medical journey, often find themselves in a relatively powerless and subordinate position, lacking equality and the right to participate in active dialogues.Their rights and interests are not adequately reflected or respected, leading to distrust in medical technology, ethics, suspicions of doctors' diagnostic and treatment behaviors, and doubts about their motivations.Consequently, medical staff endure not only the high risks and uncertainties of medical practices but also the psychological confusion accompanying patients' lack of understanding, cooperation, and respect.This culminates in the crisis of trust between doctors and patients, resulting in tense doctor-patient relationships.The intensified tension further aggravates the trust crisis, perpetuating disharmony within the medical environment and creating a vicious cycle.In makeshift hospitals during the epidemic, doctors and patients are interconnected within a community of shared destiny.Patients exhibit trust and respect towards medical staff, while medical staff reciprocate with trust and care.This positive interaction fosters a harmonious and friendly state in the doctor-patient relationship, promoting stable trust between the two parties.Ultimately, the doctor-patient relationship revolves around the interactions between individuals.Harmonious coexistence between people depends on mutual trust, as distrust engenders disharmony and potential conflicts.The foundation of a harmonious doctor-patient relationship lies in mutual trust between doctors and patients.Without trust, tension emerges between the two parties.Therefore, the contemporary crisis of doctor-patient trust serves as a significant catalyst for tension between doctors and patients.
