CSE - computer self-efficacy; PIIT - personal
innovativeness in the domain of IT; EOU - ease of use; PU
- perceived usefulness; PBC - perceived behavioral control;
AFF - affect; INT - future intentions
As can be seen in Table 4, most of the rela-
tionships taken from DTPB and TAM received at
least partial support, although there were excep-
tions. Affect was found to have a moderate and
significant influence on long term intentions at
both Time 1 and Time 2, suggesting that people
will expect to do things that they enjoy doing.
Perceived usefulness exerted a moderate and
significant influence on affect and a moderate
(Time 2) or strong (Time 1) influence on inten-
tions. Thus, the influence of perceived usefulness
was only partly mediated by affect.
Perceived ease of use exerted a strong influence
on affect at both Times 1 and 2, but the relative
influence declined somewhat at Time 2. This result
is consistent with other studies that have found
that the direct influence of EOU tends to decrease
over time (e.g., Venkatesh et al., 2003). At Time
2, perceived ease of use exerted a moderate and
significant influence on perceived usefulness; this
effect was not significant (at the p < 0.05 level) at
Time 1. This result is consistent with most prior
research, suggesting that the influence of ease of
use on usefulness becomes stronger with direct
experience.
Perceived behavioral control showed no sig-
nificant influence on intentions at Time 1, but a
significant influence at Time 2. Thus, for this group
of individuals, control beliefs have a stronger effect
following greater experience with the behavior.
