The perceived ease of use of an information
technology will have a positive influence on
affect toward using the technology (DTPB,
TAM).
Perceived ease of use of an information
technology will exert a positive influence
on perceived usefulness of the technology
(TAM).
Perceived behavioral control will exert a
positive influence on intentions to use an
information technology (DTPB).
Computer self-efficacy will exert a positive
influence on perceived behavioral control
(DTPB).
Social factors will exert a positive influence
on intentions to use an information technol-
ogy (DTPB).
Although we would anticipate that the influence
of specific self-efficacy would be stronger than
general CSE, general CSE has been shown to
exert a positive influence on perceived useful-
ness of a specific IT (e.g., Compeau & Higgins,
1995a; Compeau, Higgins, & Huff, 1999). The
associated hypothesis is:
H2: Computer self-efficacy will have a positive
influence on perceived usefulness of an informa-
tion technology.
Venkatesh and Davis (1996) posited that
computer self-efficacy should act as a precursor
to perceived ease of use. Individuals who are
confident in their ability to learn to use infor-
mation technologies are likely to view specific
information technologies as easier to use than
their counterparts who are less confident in their
ability to learn. The results from their empirical
testing provided support for this proposition.
Agarwal et al. (2000) also observed a positive
influence of self-efficacy on perceived ease of
use, as did Venkatesh (2000). This leads to the
following hypothesis:
In addition to a direct influence on intentions
as depicted above, there may be additional roles
for perceived behavioral control (PBC). In their
study of technology adoption and use, Mathieson
et al. (2001) argued that perceived resources (a
subset of PBC) included personal assets such
as an individual's expertise. In addition, they
suggested that perceived ease of use would be
influenced by expertise. As a result, Mathieson
et al. (2001) concluded that perceived resources
should influence perceived ease of use, and they
observed empirical support for this relationship.
The resulting hypothesis is:
H3: Computer self-efficacy will exert a positive
influence on perceived ease of use of an informa-
tion technology.
Compeau and Higgins (1995b) argued that
computer self-efficacy should influence affect
toward using an information technology. If an
individual is confident in his or her ability to
learn to use an information technology, he or she
is more likely to have positive affective reactions
to using the technology. In testing this relation,
Compeau and Higgins (1995b) observed a sta-
tistically significant, though small, influence in
a cross-sectional design. Compeau et al. (1999)
further observed that self-efficacy measured at
one point in time exerted an influence on affect
measured one year later. From these findings, the
associated hypothesis is:
H1: Perceived behavioral control will exert a
positive influence on perceived ease of use of an
information technology.
In addition to the potential influence of com-
puter self efficacy (CSE) on PBC, there is evidence
from other research that CSE might influence
additional factors within the DTPB model. If
an individual is confident in his or her ability
to learn to use an information technology, he or
she is more likely to believe that he or she will
be able to put the technology to productive use.
