Influencing factors of continuance intention of medical applications for the elderly.

Medical application is an effective extension of traditional medicine, which can provide users with convenient medical health and management services. However, how to improve the continuous acceptance and use of medical applications and relieve medical pressure has become an urgent issue to be explored. This study was intended to reveal the factors influencing the continuance intention of medical applications among the elderly. This study integrated the Value-Based Adoption Model, technology acceptance model, expectation confirmation theory, and trust model to construct an acceptance model for the continuous use of medical applications in the elderly. Quantitative empirical research was carried out by questionnaire survey and structural equation model. The results showed that confirmation significantly affected perceived ease of use and perceived usefulness. The perceived value, trust, satisfaction, perceived ease of use and perceived usefulness had a direct and significant positive effect on the continuance intention of medical applications in the elderly. In addition, perceived usefulness and perceived ease of use had a positive effect on satisfaction and trust. Meanwhile, perceived usefulness, perceived trust and value play a mediating role to some extent. However, the impact of privacy concern on perceived value and continuance intention was not significant. This study has expanded the technology acceptance model and its application, which can provide relevant improvement and optimization measures for medical application developers, providers, managers and researchers. It is expected to improve the user's continuance intention of medical applications, promoting the healthy and sustainable development of mHealth.
