The results of the current study showed that PU positively
affects user attitude. However, PEU did not significantly affect user
attitude. This finding is similar to the conclusion of Davis (Davis
et al., 1989); when users perceive that they can effectively use a
system, the PEU no longer directly affects the use of that system.
In other words, PU is a primary factor and PEU is a secondary factor
in user attitude. Van Raaij and Schepers (Van Raaij & Schepers,
2008) also found that PU has a much stronger positive influence
on actual use behavior than does PEU. This is primarily because
when users decide that a system is useful, they attempt to overcome the difficulties of using the system to increase their task performance. Therefore, new technologies or systems should foremost
fulfill PU; nevertheless, PEU can also significantly increase the
acceptance of and behavioral intention to use new technologies
and systems. Last, user attitude is positively related to behavioral
intention. The results of this study echo the findings of Davis,
Bagozzi, and Warshaw (Davis et al., 1989) that as the practicality
of a technology increases, so do the positive attitudes and behavioral intentions toward, and the likelihood of using that
technology.
