The scales for the motivational variables were rooted in the Technology Acceptance Model developed by Davis
(1989; 1992) and Saade, Nebebe & Tan (2007). Their scales (attitude toward behaviour, perceived usefulness, and
intrinsic motivation) were replicated in this research study. The items of the original scales were put in a random
order, and participants were invited to give a score on a 5-point Likert scale.
