The purpose of this study was to examine the relationship among romantic attachment, self-esteem, and love attitudes as perceived by college students(male:149, female:202) in the Seoul and Gyeonggi areas. All respondents submitted their answers on a self-report questionnaire. The measurement instruments were Brennan, Clark, & Shaver'(1998) 'Multi-item Measure of Adult Romantic Attachment', Rosenberg'(1979) Self-esteem Scale, and Hendrick, Hendrick, & Dicke'(1998) 'Love Attitudes Scale'.
