Background: Mobile health services are gradually being introduced to support patients’ self-management of chronic conditions. The success of these services is contingent upon patients’ continuous use of them. Objective: This study aims to develop a model to measure the success of patients’ continuous use of mobile health services for the self-management of chronic conditions. Methods: The proposed model was derived from the information systems continuance model and the information systems success model. This model contains 7 theoretical constructs: information quality, system quality, service quality, perceived usefulness, user satisfaction, perceived health status, and continuous use intention. A web-based questionnaire survey instrument was developed to test the model. The survey was conducted to collect data from 129 patients who used a mobile health app for hypertension management from 2017 to 2019. The questionnaire items were derived from validated instruments and were measured using a 5-point Likert scale. The partial least squares modelling method was used to test the theoretical model. Results: The model accounted for 58.5% of the variance in perceived usefulness (R2=0.585), 52.3% of the variance in user satisfaction (R2=0.523), and 41.4% of the variance in patients’ intention to make continuous use of mobile health services (R2=0.414). The continuous use intention was significantly influenced by their perceived health status (β=.195, P=.03), perceived usefulness (β=.307, P=.004), and user satisfaction (β=.254, P=.04) with the mobile health service. Information quality (β=.235, P=.005), system quality (β=.192, P=.02), and service quality (β=.494, P<.001) had a significantly positive influence on perceived usefulness but not on user satisfaction. Perceived usefulness had a significantly positive influence on user satisfaction (β=.664, P<.001). In a result opposite to the original hypothesis, perceived health status did not negatively influence patients’ intention to continue using the mobile health service but showed a significantly positive correlation. Conclusions: This study developed a theoretical model to predict and explain patients’ continuous use of mobile health services for self-management of chronic conditions and empirically tested the model. Perceived usefulness, user satisfaction, and health status contributed to patients’ intention to make continuous use of mobile health services for self-managing their chronic conditions.

衡量患者持续使用移动医疗服务进行慢性病自我管理的成功率：模型开发和验证

背景：移动医疗服务逐渐被引入以支持患者对慢性病的自我管理。这些服务的成功取决于患者对它们的持续使用。目的：本研究旨在开发一个模型来衡量患者持续使用移动医疗服务进行慢性病自我管理的成功率。方法：所提出的模型来源于信息系统持续模型和信息系统成功模型。该模型包含7个理论结构：信息质量、系统质量、服务质量、感知有用性、用户满意度、感知健康状态和持续使用意愿。开发了一个基于网络的问卷调查工具来测试该模型。该调查收集了 2017 年至 2019 年使用移动健康应用程序进行高血压管理的 129 名患者的数据。问卷项目来自经过验证的工具，并使用李克特 5 点量表进行测量。采用偏最小二乘建模方法对理论模型进行检验。结果：模型解释了感知有用性方差的58.5%（R2=0.585），用户满意度方差的52.3%（R2=0.523），以及患者持续使用手机的意愿方差的41.4%。卫生服务（R2=0.414）。持续使用意愿受其感知健康状态（β=.195，P=.03）、感知有用性（β=.307，P=.004）和用户满意度（β=.254，P=.03）显着影响。 04) 与移动健康服务。信息质量（β=.235，P=.005），系统质量（β=.192，P=.02）和服务质量（β=.494，P<.001）对感知有用性有显着的积极影响，但对用户满意度没有显着的积极影响。感知有用性对用户满意度有显着的积极影响（β=.664，P<.001）。在与原假设相反的结果中，感知健康状况并未对患者继续使用移动医疗服务的意愿产生负面影响，而是呈现出显着的正相关。结论：本研究开发了一个理论模型来预测和解释患者持续使用移动医疗服务进行慢性病自我管理，并对该模型进行了实证检验。感知有用性、用户满意度、
