The breakthrough idea of technology dependence is developed from mass communication theory as an enhancement to the evolving literature on IS Continuance. Unlike prominent constructs in the continuance literature, dependency as adapted for use here involves conscious user recognition of the benefits from and motivations for technology use, which stands in contrast to typical continuance constructs that presume routinized and nonconscious usage patterns. This study develops, tests and explains emerging dimensions of technology dependency in the context of mobile 3G handset users in a university workplace community. Results provide the basis for development of measures and hypothetical relationships with related variables for future research, and provide a valuable new variable for inclusion in the IS Continuance literature stream.
