The aim of this study is to investigate the formation and effects of general computer self-efficacy among business students. Antecedents of computer self-efficacy were investigated, and computer attitudes and MIS intention (defined as one’s intention to select MIS for his or her future study and career) were selected as dependent variables. The results supported that computer knowledge, current computing experiences, computer anxiety, and age affected the formation and development of computer self-efficacy among the sampled students; computer self-efficacy and social norms had strong effects on computer attitudes and MIS intention. Implications for both research and MIS education are also discussed.
