This paper examines the influence of contextual specificity when describing technology acceptance. Social cognitive theory provides the basis for adding several independent variables (computer anxiety, prior experience, other's use, organizational support, task structure, and system quality) and one intervening variable (computer-efficacy) to the technology acceptance model (TAM). This extended model was tested using a mail survey and the results are tabulated using partial least squares. The results show that system usage is strongly influenced by computer anxiety, prior experience, other's use, organizational support, task structure, system quality, and perceived usefulness. In addition, perceived usefulness is the strongest mediator in determining system usage. (c) 2004 Elsevier Ltd. All rights reserved.
