A model integrating rationally and socially oriented theories of computer-m
ediated communication (CRM) is developed. It was proposed that technology c
haracteristics, individual differences, Sob position and function, various
situational determinants and organizational factors would positively influe
nce employees' Internet use and attitudes. It was further hypothesized that
the Internet would substitute for more traditional forms of media (telepho
ne, printed matter) during individual's external search behavior. This mode
l was tested quantitatively and qualitatively with the use of a quasi-exper
imental, pretest-posttest design during the facilitated introduction of an
Internet-based CMC system into an organization. A particular focus of the s
tudy was an examination of the communication and information channel choice
s, use, satisfaction and adoption of the Internet-based CMC system by the e
mployees. Qualitative and/or quantitative support was found for all proposi
tions, except Internet substitutability. Key contributions and recommendati
ons for future research are discussed. (C) 2000 John Wiley & Sons, Inc.
