Studies of the effect of individual differences on usage of information systems have yielded mixed results. This study examines the effect of individual differences on the perceived relative advantage (a concept akin to perceived usefulness) of using Group Support Systems (GSS) over traditional face-to-face meetings. Specifically, the current field study investigates the effect of oral and writing communication apprehension, computer anxiety, and personal innovativeness on perceptions of relative advantage of a GSS. Results provide empirical support for the relationships explored and explain about 40% of variance in relative advantage of a GSS meeting vis-a`-vis a traditional face-to-face meeting.
