A study examined the relationship between the personality constructs of self-concept and communication apprehension and the use of self-confrontation (self-viewing of videotaped speeches) as a potential self-concept enhancement strategy. The question of whether the constructs of self-concept and communication apprehension overlap was investigated for both theoretical and empirical support, and both constructs were, additionally, related to the intervening self-confrontation variable. Subjects were 168 college students in a public speaking class who completed a self-concept scale, a report of communication apprehension, and a video confrontation scale at the beginning of the semester (before participating in public speaking activities in class) and again at the end of the semester (after each had delivered four in-class speeches). Each student was shown the videotape of his or her speech performances after each presentation. Results indicated that future speech communication self-concept research might benefit from a reexamination of the construct under consideration. Although self-concept is normally viewed as a "state" variable, the results suggested that the construct might be resistant to change in the limited communciation course context. Communication apprehension, a dimension of self-concept, however, was found to be susceptible to change in this setting. Public speaking appeared to be the intervening variable that invoked the change, while self-confrontation appeared to inhibit the reduction of apprehension. (FL)
