ABSTRACT

TRUSTING IT ARTIFACTS:
HOW TRUST AFFECTS OUR USE OF TECHNOLOGY

By

ANTHONY OSBORN VANCE

9/13/2008

Committee Chair: Dr. Detmar Straub

Major Department: Computer Information Systems

Despite recent interest in the role of trust in Information Systems, the potential of IS
to foster trust in business relationships remains largely untapped. In order to better realize this
potential, this dissertation examines three areas of IS trust research for which research is
particularly limited: (1) the IT artifact as a target of trust, (2) IS-based source credibility as an
antecedent of trust, and (3) the effect of anonymity on trust in online environments. The
objective of this dissertation is to examine the effects of IS on trust in each of these areas. To
do so, a multi-paper dissertation format is adopted in which each area examined constitutes a
distinct, though complimentary, study. Together, these studies further research on how IS can
enhance trust in business relationships.
