A study involving 215 college students was undertaken to determine the relationship between assertiveness and communication apprehension by factor analyzing the items on the Rathus Assertiveness Schedule (RAS) and on the Personal Report of Communication Apprehension (PRCA). Six factors emerged from the analysis: apprehensive about speaking, apprehensive about interpersonal communication, preventing others from taking advantage, being candid, being contentious, and making complaints in restaurants. Of the six factors, the first came exclusively from the PRCA, the second from both instruments, and the remaining four exclusively from the RAS. The linkage between assertiveness and apprehension about communication, as measured by these two instruments, appears to be apprehension about interpersonal communication. The findings generally confirm the previously established factor structure of the RAS; however, they challenge the unidimensionality of the PRCA. (FL)
