Does knowledge matter to seniors' usage of mobile devices? Focusing on motivation and attachment

Purpose - The purpose of this study is to investigate the relationships among determinant (ease of use), extrinsic (usefulness) and intrinsic motivations (enjoyment), attachment and usage intention regarding seniors' use of mobile devices for tourism. In addition, this study examines the moderating role of knowledge in these relationships. Design/methodology/approach - The researchers collected data via online surveys to reach the target population of this study, 55 years and older adults who had used mobile devices for tourism. The researchers used the partial least squares approach for this study. Findings - The results reveal that ease of use has significant effects on extrinsic and intrinsic motivations. The motivations of usefulness and enjoyment significantly affect attachment, which, in turn, influences usage intention. The relationships between ease of use and usefulness, ease of use and enjoyment and enjoyment and attachment were stronger for the high-knowledge group than for the low-knowledge group. The relationship between usefulness and attachment was stronger for the low-knowledge group than for the high-knowledge group. Research limitations/implications - The findings of this study provide compelling implications for academics and practitioners in the senior tourism field. Originality/value - The compelling insight of this study is the development of a research model that combines an emergent construct of attachment as a mediator and knowledge of technology as a moderator.
