The purpose of this study was to investigate the relationship between the romantic attachment and interpersonal problems of college students. The subjects of this study were 220 college students in Seoul and A-san. The romantic attachment was assessed by the multi-item measure of adult romantic attachment (Brennan et al., 1998) and the interpersonal problems were assessed by KIIP (Cho & Park, 2005). The major findings of this study were as follows: First, 44.5% of the subjects were classified as fearful, 26.8% as secure, 18.6% as dismissing, and 10.0% as preoccupied. Second, a significant difference among romantic attachment groups was found with the fearful group reporting a higher level of interpersonal problems than the secure and dismissing groups. Gender was a significant factor on independent problem in interpersonal problems. Third, avoidance and anxiety of romantic attachment dimensions were positively correlated with interpersonal problems. There was a gender difference in the relationship between avoidance of romantic attachment dimension and overgenerous in interpersonal problems. Avoidance of romantic attachment dimension in female students was negatively correlated with overgenerous in interpersonal problems.
