Hwang, Soonhee The purpose of this study is to explore the relationships between leadership in college students and speech related variables such as communicative apprehension and communicative traits. According to the examination of domestic studies concerning the leadership and factors related to speech, few studies have focused on these relationships. This study was conducted with 323 engineering students and 131 humanities college students at P University. Findings showed that firstly, there were significant gender and grade differences in leadership of college students. Second, there were significant gender and grade differences in communicative apprehension. Third, there were significant gender differences in verbal aggressiveness. However, there were no significant gender, grade and major differences in argumentativeness. Besides, we found a high correlation among leadership, communicative apprehension and communicative traits. From these findings, it is needed to refine the instructive modules of speech as well as verify their validities.
