As computers have increasingly provided new channels of communication, scholars have taken an interest in computer-mediated communication (CMC) in general and the impact of personality traits and other antecedents of preference for face-to-face or computer channels. Research is hampered, however, by the lack of standardized measures of CMC-related concepts. Three studies (N = 914) were undertaken to develop and validate a measure of affect for using communication channels. Findings of the studies provide strong evidence of the internal consistency and both construct and predictive validity of the scale.

Research was conducted to test the effectiveness of a skills‐based program as a method for reducing anxiety during public speaking. Twenty‐five Japanese college sophomores were exposed to a systematic approach for developing a presentation that was theoretically linked to mechanisms to reduce communication apprehension (CA). Students gave four presentations that were graded by both teacher and peer evaluation. Results indicated that the experimental group reported a significantly greater drop in public speaking anxiety than did a control group of 86 students.
