The purpose of this study was to investigate the relationships among types of self-expression, interpersonal stress events, and stress responses in the first-year university students. An assertive-checklist, an interpersonal stress events scale and a stress response scale was administered to 175 first-year university students. On this basis, a cluster analysis on the scores of self-reported assertive-checklist, students were divided into 3 groups, nonassertive, assertive, and aggressive. The results of analysis of variance revealed that the assertive participants had the lowest interpersonal stress events and stress responses. On the other hand, the aggressive students had the highest interpersonal stress events and stress responses. These results suggested that type of self-expression was related to interpersonal stress events and stress responses.
