BACKGROUND mHealth services enable real-time measurement of information on individuals' biosignals and environmental risk factors; accordingly, research on health management using mHealth is being actively conducted. This study investigates attitudes toward an mHealth personalized healthcare service app (currently in development, featuring wearable devices) among the elderly in South Korea. OBJECTIVE The study aims to identify factors that influence older people's intention to use mHealth and to verify whether the presence of chronic disease moderates the effect of the identified factors on their behavioral intentions. METHODS A cross-sectional study was conducted among 500 participants aged 60 to 75. The research hypotheses were tested using structural equation modeling, and indirect effects were verified through bootstrapping. Bootstrapping was performed 10,000 times, and the significance of the indirect effects was confirmed through the bias-corrected percentile method. RESULTS Of 477 participants, 278 (58.3%) had at least one chronic disease. Performance expectancy (beta=0.453, P=.003) and social influence (beta=0.693, P= CONCLUSIONS To encourage older people to use personalized healthcare services, it is important to clearly demonstrate and emphasize their benefits in terms of healthcare management. The awareness of people around them also plays an important role. In particular, it is necessary to promote such services at the family and community levels; this aspect is particularly important in the Confucian culture. In addition, support from service providers should be strengthened, so that older people trust that they have consistent access to technical support. Overall, if people with chronic diseases have confidence in a wearable device for measuring biosignals, a higher utilization rate could be achieved. |
