The purpose of this study is to explore the relationship between gender role conflicts and career barriers among middle school boys, and to ensure whether in the relationship between gender role conflicts and career barriers, the Career Decision Self-efficacy felt plays a medium or not. The study finally analyzed the data of 150 middle school boys in Seoul. The results of this study are summarized as follows. First, when we looked at the correlation between major variables, the gender role conflicts showed significant static correlation with the path barrier, and showed significant amulet correlation with the protelege sense. The path setter showed a significant amulet correlation with the path barrier. Second, it is confirmed that the relationship between gender roles conflicts and the barrier to the path is correlated with the direction maker, Gi-young. The study shows that the effects of the Career Decision Self-efficacy on the relationship between gender roles conflicts and career barriers are negatively influenced by the effects placed on middle school boys. The above findings call for counseling strategies to enhance the Career Decision Self-efficacy as a way to lower the perception of the barriers in career counseling that is intended to help middle school boys make career choices and make career decisions.
