정보시스템 수용의 외생적 및 내재적 동기의 효과에 대한 개인적 관여도의 조절효과

For the success of information systems(IS), user acceptance is very important. The effect of attitude on intention to use has shown inconsistent results because of the direct effects of extrinsic motivation (i.e., Perceived Usefulness) and intrinsic motivation(i.e., Perceived Enjoyment). To find the mechanisms that regulate the relative strength of direct and indirect effects of those motivations on attitude, this paper adopted the Elaboration Likelihood Model (ELM) for attitude change with personal involvement as the moderating factor. For an empirical exploration, about two hundred samples were collected from the users of a package software. Data analysis using Structural Equation Modeling (SEM) shows that involvement plays a key role for linking perceived usefulness to cognitive attitude and perceived enjoyment to affective attitude. Another point of interest is that the intention to use is not related with any of its supposed antecedents. Our analysis result implies that TAM constructs are not related with intention in isolation but with attitude if we include the personal involvement.
