Intentions to Use Information Technologies

An integrative model explaining intentions to use an information technology is proposed. The primary objective is to obtain a clearer picture of how intentions are formed, and draws on previous research such as the Technology Acceptance Model (Davis, Bagozzi and Warshaw, 1989) and the Decomposed Theory of Planned Behavior (Taylor and Todd, 1995a). The conceptual model was tested using questionnaire responses from 189 subjects, measured at two time periods approximately two months apart. The results generally supported the hypothesized relationships, and revealed strong influences of both personal innovativeness and computer self-efficacy.
