The test construction procedures included the selection of questionnaire items based upon constructs of the Homosexual Identity Formation Model, establishment of interrater and interitem reliability for those items, and refinement of the GIQ through two pilot tests. The GIQ is a brief measure that may be used by clinicians and researchers for identifying gay males in the various stages of homosexual identity formation. This article describes the development of the Gay Identity Questionnaire (GIQ) which was derived from tenets of the Homosexual Identity Formation (HIF) model proposed by Cass in 1979.
