This paper discusses the role of self-efficacy to computer novices through a longitudinal study. The researchers conducted this study by collaborating with three non-government organizations (NGOs) for which funding was received from one government unit and a large local charitable organization. A new model was developed to examine the influence of Internet self-efficacy and outcome expectations on usage intention and perceived user competence. Behavioral modeling training courses were offered to matured adults aged 50 and above in two separate studies over a year. Questionnaires and cognitive knowledge assessments were distributed. In general, the findings in the two studies validated the impacts and antecedents of Internet self-efficacy and outcome expectations on usage intention. Limitations and implications of this study are provided following the sections on research model and hypotheses, design and discussion on findings
