Abstract
Several research efforts over the last decade have attempted to augment the basic technology acceptance model (TAM) by identifying and testing determinants of the two key predictor beliefs of the modelóperceived usefulness and perceived ease of useóand by identifying other extraneous variables that moderate various model relationships. This research is an attempt in the same direction. It addresses some key gaps and inconsistent findings in the TAM literature to further contribute to the refinement of TAM. In this endeavor, this research draws from social cognitive theory (SCT), computer self-efficacy (CSE), technology acceptance model (TAM), and the risk management literature to develop an extended TAM that includes new relationships between the model constructs and personal innovativeness and general and specific computer self-efficacy. The research will be conducted as a survey in the context of the personal digital assistant (PDA) technology.
