Abstract
This study uses data collected by a survey of computer-based medical information system end-users in a large hospital in the southeastern United States. The theoretical model examined using this data links several antecedents to the end-users’ organizational commitment, mediated by computer self-efficacy and outcome expectancy. These antecedents are past computer experience of the end-user, computer staff support for the computer system, ease of system use, and the degree of system use (i.e., percentage of time the system is used by the end-user). The empirical results indicate that past computer experience and the degree of system use positively influence the end-user’s organizational commitment through both computer self-efficacy and outcome expectancy. These also show that computer staff support and ease of system use positively impact the end-user’s organizational commitment through outcome expectancy. From these results, conclusions and implications for practicing managers are discussed.
