Revision and extension of a multidimensional measure of sexual minority identity: The Lesbian, Gay, and Bisexual Identity Scale.

Published: February 14, 2011


Two studies were conducted to investigate a revised and extended version of the Lesbian and Gay Identity Scale (Mohr & Fassinger, 2000): the 27-item Lesbian, Gay, and Bisexual Identity Scale (LGBIS). This revision features more inclusive and less stigmatizing language than the previous version and includes 2 new subscales assessing identity affirmation and centrality. In Study 1, an exploratory factor analysis (n = 297) and a confirmatory factor analysis (n = 357) supported an 8-factor solution assessing acceptance concerns, concealment motivation, identity uncertainty, internalized homonegativity, difficulty with the identity development process, identity superiority, identity affirmation, and identity centrality. Predicted associations with measures of identity-related constructs and psychosocial functioning provided preliminary validity evidence for LGBIS scores in a college student population. Study 2 (N = 51) provided evidence of the test-retest and internal consistency reliability of LGBIS scores. These studies suggest that the LGBIS may offer researchers an efficient means of assessing multiple dimensions of sexual orientation minority identity.
