The purpose of this study was to construct a scale to measure the “Gender Identity”, and examine its reliability and validity. First, fifty-six items were rated by 184 male students, and fifty-seven items by 454 female students. Exploratory factor analysis yielded three factors. Three subscales were constructed for both male and female. These subscales were “accepting one's sex or gender”, and “identification with parents”, and “intimacy with the opposite sex”. Each subscale contained ten items. Second, Cronbach's coefficient alpha provided some supports of reliability for each subscale. Third, confirmatory factor analysis provided some supports of validity to create three subscales.
