A user’s interaction with an Information System (IS) could transpire in two ways: direct and indirect. While most prior literature examines the direct interaction between a user and the system, few have examined and differentiated between direct and indirect use. In this study, we anchor on the theory of psychological attachment to study the effects of various external social factors on direct-usage and indirect-usage of an organizational IS. Survey results from 102 physicians in a public hospital reveal that punishment and informational influence are significantly related to direct-usage of the Electronic Medical Record System (EMRS) by physicians. Punishment and image are significantly associated with indirect-usage of EMRS.
