Technological advancements have enhanced the delivery of goods and services in both the public and private sectors. The continued diffusion of diverse Internet-based innovations has increased the need for more research on citizen use and perceptions of technology services. In this study, we explore the role of IT mindfulness and extended use of technology on citizen use of e-government related systems’ affordances. To test the proposed model, we administered a survey to 108 U.S. citizens. The results indicate both IT mindfulness and extended use have a significant, positive impact on e-government systems’ related affordances. Implications for research and practice are discussed.
