In 2002, I developed the Gay Affirmative Practice Scale (GAP) while pursuing my PhD at the University of Texas at Austin. The GAP has 30 items that comprised two 15-item domains: the belief domain and the behavior domain. The scale can be administered as a 30 item scale or with only one of the 15-item domains. The scale has been subjected to rigorous reliability and validity testing and is considered the only measure developed to assess this construct (that of Gay Affirmative Practice). The scale has been used by practitioners, researchers, educators, & students in several different disciplines and countries. I make it available at no cost to those who wish to use it in research & practice. If you would like to use it, please complete the form at this link.
Additional information about the GAP and its psychometric properties can be found in this article:
