The purpose of this study was to develop Gender Identity Scale (GIS). In previous studies, gender identity was measured as specific gender roles and/or sexual orientation that the person assumed. The new scale, however, was to measure the sense of identity with one's gender, based on the identity theory of Erikson. Participants in the preliminary study were university students, 153 women and 153 men, who completed the new scale. Several models were tested against the data: two factor, four factor, and hierarchical models. The hierarchical model, with two higher-level factors and two lower-level factors each, was the best fit. In order to examine validity of GIS, the new scale, university students, 205 women and 207 men, completed it along with such other scales as gender role, gender acceptance, and self-esteem. In addition, people with gender identity disorder, 120 MTF (male to female) and 155 FTM (female to male), responded to the scale. Results indicated that the scale had adequate validity.
