Results show that privacy concern, perceived risk, and perceived intrusiveness influenced continuance intention mainly through psychological need satisfaction and enjoyment rather than usage frequency.

摘要

This study examines how multidimensional privacy perceptions relate to continuance intention toward AI tools among older adults. Drawing on Self-Determination Theory, survey data from U.S. adults aged 60 and older who had used AI tools for at least one year (N = 224) were analyzed using serial mediation models across multiple AI tool types. Results show that privacy concern, perceived risk, and perceived intrusiveness influenced continuance intention mainly through psychological need satisfaction and enjoyment rather than usage frequency. In contrast, perceived privacy control showed both psychological associations and tool-specific indirect associations through frequency of use. These findings suggest that privacy in AI contexts is more strongly related to the quality of users’ motivational experience than to the quantity of use, underscoring the role of psychological need support in sustained AI engagement.
