Purpose: The purpose of this study was to compare and examine gender role identity and sexual attitude according to sex among college students. Method: The subjects consisted of 1,118 college students. The tool for gender role identity and sexual attitude was the Korea Gender Role Identity Inventory(KGRII) of Lee, Kim and Koh(2002) and the Sexual Attitude Scale of Koh, Kim and Lee(2005). The collected data was analyzed using descriptive analyzed statistics, $X^2$ test, Lamda, t-test, ANOVA, Sheffe and Pearson correlation with the SPSS WIN 12.0 program. Result: For male students, undifferentiated role identity type, 36.5%, was the most common but for female students, an androgynous role identity type, 39.3%, was most common. The sexual attitude score according to gender role identity type was 2.9 for the undifferentiated type as the highest score. Of both male and female students, the highest sexual attitude score was the undifferentiated type. Sexual attitude according to general characteristics for male students had a significant difference in major field of study and height and for female students weight. Sexual attitude was significantly related to age, height and weight. Conclusion: These results suggest that gender role identity and sexual attitudes are different between the sexes. This study result contributes to providing basic data for sex education and nursing interventions for college students.
