Antecedents for Older Adults' Intention to Use Smart Health Wearable Devices-Technology Anxiety as a Moderator.

The increase in the demands for surveillance of chronic diseases, long-term care, and self-health management has allowed mobile smart health wearable devices to become products with greater business potential in past years. Wearable devices being able to be worn for long periods are the most suitable for 24-h weatherproof monitoring. Nevertheless, most technological products are not developed specifically for older adults. Older adults might be apprehensive and fearful about the use of technological equipment and might appear "technologically anxious", so it was wondered whether older adults could smoothly operate and comfortably use smart wearable device products, and how "technological anxiety" would affect their behavior and attitude towards using these devices. The variables of "technology readiness", "technological interactivity", "perceived usefulness", "perceived ease of use", "attitude", and "intention to use" are therefore discussed in this study. Taking "technological anxiety" as the moderating variable to develop the questionnaire scale, the quantitative research with structural equation model is applied to discuss the older adults' intention to use smart health wearable devices. The questionnaire was distributed to older adults' community care centers, senior centers, and senior learning centers in Taiwan, and to an older adults' group above the age of 60 with experience in using smart bracelets. A total of 200 questionnaires were distributed, and 183 were retrieved, with 166 valid copies. The research results reveal that users with higher technology readiness, and older adult users with higher technological interactivity, present a higher perceived ease of use and perceived usefulness. Technological anxiety would affect users' attitude and further influence the intention to use. The research results could help understand older adults' needs for using smart health wearable devices.
