We investigate the EDT models in a longitudinal survey of undergraduate business students usingMicrosoft Access. Access is an appropriate technology to use because it is similar to other technologies forwhich both ease of use and usefulness beliefs have been examined (e.g., Bhattacherjee & Premkumar,2004; Davis et al., 1989). EDT is not specific to any product or technology, so it should be applicable toMicrosoft Access. The US university students were enrolled in an introductory information systems course.While Access use was required for the course, EDT applies to both mandatory and voluntary contextsbecause satisfaction (unlike constructs like use and intention) can measure IT’s effectiveness or successregardless of any requirements to use the technology (Bhattacherjee & Premkumar, 2004; DeLone &McLean, 2003; Khalifa & Liu, 2004). For example, individuals who are required to use a technology everyday for work may still think it is not a success because they are dissatisfied with it. To make continuanceintention applicable in this mandatory context, we measured the items after the required coursework andreferred to students’ continued use after the course (Bhattacherjee & Premkumar, 2004). Students are anappropriate sample because findings from student-based adoption studies have generally been consistentwith those done in the field (Lee, Kozar, & Larsen, 2003). Also, student subjects have been used in prior ITEDT studies (e.g., Bhattacherjee & Premkumar, 2004; Spreng & Page, 2003). Participants were 48 percentmale with the average age 21. On average, they had used computers for 11 years and their previousAccess experience was 2.9 on a scale of 1 (no experience) to 7 (extensive experience).
