After theory of reasoned action, Davis (1986, 1993) and Davis, Bagozzi, and
Warshaw (1989) proposed the Technology Acceptance Model to account for how
perceived ease of use, perceived usefulness, and attitudes predict behavio
ral intention to use computers. This study combined these factors with meas
ures from Bandura's self efficacy theory (computer self efficacy and comput
er anxiety; Bandura, 1977, 1986) in conjunction with assessments of current
computer experience. A total of 147 undergraduates completed a series of q
uestionnaires at the beginning and end of a 13-week semester. A multiple re
gression analysis revealed that self-reported word-processor usage over a 1
3-week period was predicted by levels of usage at the beginning of the seme
ster, expected usage, and perceived usefulness. Initial levels of usage and
perceived usefulness were both predicted by levels of computer anxiety. A
combination of the variables formulated by the Technology Acceptance Model
and self efficacy theory account for 45% of the variance in self-reported c
omputing behavior over a 13-week period. The theoretical implications are d
iscussed. (C) 1999 Elsevier Science Ltd. All rights reserved.
