  • The purpose of this study was to translate and validate the Lesbian, Gay, and Bisexual Identity Scale(LGBIS), which is a scale measuring the multidimensional identities of sexual minorities. For this, we conducted an exploratory factor analysis using a sample of 201 LGBs(homosexuals and bisexuals). Identical to the original scale, eight factors were extracted from the translated scale(i.e., concealment motivation, identity uncertainty, internalized homonegativity, difficult process, acceptance concerns, identity superiority, identity centrality, and identity affirmation), but one item was removed. In addition, the reliability coefficients of the eight factors except for concealment Motivation were satisfactory. The Confirmatory factor analysis revealed that the 8-factor model had a good fit to the data. Finally, to verify the criterion validity, correlation among each eight factor and the scales measuring the identity related scale and the psychological-functioning scale were analyzed. In conclusion, the Korean version of the LGBIS consists of 8 factors and 26 items in total. Also it was found to be a valid measure for LGBS in Korea as well.
