Attitude to Use Information and Communication Technology in Older Adults Under "Stay Home" to Prevent COVID-19 Infection

Owing to the global COVID-19 (coronavirus disease 2019) pandemic, many people have been forced to adopt a new lifestyle that makes extensive use of information and communication technology (ICT) under the slogan "Stay Home." Because older adults have been reported to be more resistant to information technology, such rapid changes in their lifestyle would be more difficult for them to accept. However, some senior citizens have used ICT or have improved their ICT skills since the COVID-19 pandemic. Analyzing the current situation of older adults may allow for a detailed analysis of the acceptance process of information technology. In this article, we aim to clarify the mechanism of acceptance and use of information technology among older adults in terms of social conditions, support systems, and the usability and accessibility of interfaces. The results indicated that the transtheoretical model of behavior change in terms of interest and usage status of ICT/IoT services can be used to categorize technology acceptance situations.
