Lesbian, gay, and bisexual youth are particularly vulnerable to various types of victimization, and it is also likely that psychological consequences of victimization are more severe among youth than among older lesbians, gay men, and bisexuals. The trend toward increased openness and assertiveness on the part of homosexuals puts them in direct conflict with family and peers and with traditional institutions and support systems. The amplified social vulnerability of lesbian, gay, and bisexual youth to victimization is especially problematic because of the distinctive character of their adolescent years. Developmental issues during adolescence are examined, as well as distinctive life stresses, the incidence of suicide, and victimization patterns. Interventions to prevent violence against lesbian, gay, and bisexual youth are discussed, and public policy recommendations are offered. 97 references and 1 table
