Despite the growing clinical and research literature dealing with gay, lesbian, and bisexual (GLB) issues, mainstream psychology has tended to ignore much of the work that has been done in this area. This article illustrates how clinical and research writings on GLB issues continue to remain invisible to mainstream psychology in such areas as life span development and aging, teenage suicide, substance abuse, victimization and abuse, and family and couple relationships. It also deals with some of the determinants of well-being among GLB individuals, such as family support, and notes the benefits accruing to mainstream psychology from studying GLB issues. A network of family members within psychology having GLB relatives has been formed--AFFIRM: Psychologist Affirming Their Gay, Lesbian, and Bisexual Family--and is dedicated to supporting its own family members, encouraging other family members to do likewise, supporting research and clinical work on GLB issues, and closing the gap between GLB clinical and research work and mainstream psychology.
