Despite its popularity in the USA, the most common communication apprehension (CA) measurement scale, the Personal Report of Communication Apprehension scale (PRCA-24), has been used in just three studies in Japan. Further, validity analyses have not been reported for Japanese samples. This article attempts to analyze the content validity of the PRCA-24 on Japanese college students. Results indicate that the PRCA-24 may be of use in determining some, but not all, types of CA among Japanese students. Suggestions for future CA research in Japan are offered.
