2型糖尿病患者使用E-health管理疾病意愿与影响机制
Type 2 diabetes patients use E-health to manage disease willingness and influence mechanisms
摘要
Abstract
Objective:To comprehensively investigate how the willingness of patients with type 2 dia-betes mellitus to use E-health technologies,such as the application(APP)or Wechat mini-programs and the underlying influencing factors works for its mechanisms.Methods:Based on the extended technology acceptance model,a cross-sectional questionnaire survey was conducted among 559 patients with type 2 diabetes from six provinces or municipalities in the eastern,central,and western regions of China from November to December 2024.The survey aimed to investigate the patients'willingness to use APP or Wechat mini-programs and the influencing factors.Correlation analysis and structural equation modeling methods were used to analyze the influencing factors of patients' willingness to use and to explore the mechanisms.Results:A total of 559 patients were surveyed,with an average willingness score of 10.68(out of a total score of 15).Age and education level were found to be influencing factors of willingness to use,younger age and higher education(high school/college)were significantly associated with stronger willingness to use(P＜0.05).Spearman correlation analysis revealed that perceived usefulness,per-ceived ease of use,disease perception,social support,self-efficacy,and external cues were positively correlated with willingness to use,while perceived barriers were negatively correlated(all P＜0.05).Structural equation modeling demonstrated direct effects of perceived usefulness(β=0.375,P＜0.001),disease perception(β=-0.240,P＜0.001),self-efficacy(β=0.313,P=0.019),social sup-port(β=-0.336,P=0.042),and external cues(β=0.609,P＜0.001)on willingness to use.Per-ceived ease of use indirectly influenced willingness through perceived usefulness(total effect=0.374).Self-efficacy affected usage intention partially mediated by disease perception,external cues influenced intention through perceived usefulness,and perceived barriers impacted intention via perceived useful-ness,with external cues exhibiting the strongest total effect(β=0.672).All these effects were statisti-cally significant(P＜0.05).Conclusion:Patients with type 2 diabetes mellitus have a high willingness to use E-health technologies like APP or Wechat mini-programs,particularly younger individuals and those with high school/college education.Increasing perceived usefulness,self-efficacy,and external promotion can enhance willingness to use.However,higher disease perception and higher social support are associated with decreased willingness to use.Perceived ease of use and self-efficacy can also affect willingness to use through multiple mechanisms.关键词
