Expanding Mobile Information Service Needs to Improve Quality of Life: A Cross-temporal Comparison of Japanese Students
The purpose of this paper is to identify how the use of mobile information services (MIS) contributes to the quality of life (QoL) of young Japanese users. We examined the relationship between individual life domains and the overall QoL via the bottom-up spillover theory. Questionnaire surveys were conducted online among young Japanese mobile users studying in a university. We obtained data from 107 effective respondents. Comprehensive analyses of the relationships between constructs were conducted using partial least squares structure equation modeling (PLSSEM), which is an analytical method considered appropriate for research models of a non-established nature, many constructs, and a small sample size. The results of this study clearly indicated that the relationship between individual contribution and overall contribution is valid and reliable. Leisure life had the greatest influence on overall contribution among Japanese young adults. Further, there were some changes between 2013 and 2015 with respect to more positive and significant individual life domains, which are as follows in descending order: cultural life, community life, informational life, home-healthcare life, financial life, trustworthy life, health life, and safety life.
