Delineating the effects of general and system-specific computer self-efficacy beliefs on IS acceptance

This paper discusses extensions to previous research on computer self-efficacy (CSE) and systems acceptance by examining the impact of multilevel CSE on IS acceptance. Based on the technology acceptance model (TAM), we examined the effects of general and system-specific CSE on perceived ease of use, perceived usefulness, and behavioral intention to use a system. The results of a field experiment indicated that system-specific CSE represented a stronger predictor of perceived usefulness and behavioral intention than general CSE. In contrast, general CSE had a stronger effect on perceived ease of use. The research and practical implications of these findings are discussed. # 2006 Elsevier B.V. All rights reserved.
