The innovation attributes of relative advantage and complexity were measured using multi-item index scales, which were modified versions of those used in other empirical studies of technology driven innovations (Davis, 1989; Merisavo et al., 2007; Moore and Benbasat, 1991; Pavlou, 2003). Compatibility, the third innovation attribute, was also measured with a multi-item scale. However, in this instance, the scale was originally developed by the researcher to suit the unique requirements of the current research setting. Although the researcher examined several measurement scales for this construct, many of the already established items could not be suitably modified to
