The long-term impact of homophobic stigmatization on adolescents with lesbian parents has not been explored. This longitudinal study investigated the effects of homophobia experienced during adolescence on problem behavior among emerging adult offspring of lesbian parents. The 72 offspring (37 females and 35 males; all cisgender and 25 years old) were predominantly White, heterosexual, and highly educated. As 17-year-old adolescents, 40.3% (n = 29) reported that they had been treated unfairly because of having lesbian parents. Experienced homophobia during adolescence was indirectly associated with internalizing problems during emerging adulthood through psychological problems during adolescence and meaning in life in emerging adulthood. Adolescent experiences of homophobia were also indirectly related to externalizing problems during emerging adulthood through adolescent psychological problems, but not through meaning in life in emerging adulthood. These findings indicate that long-term effects of homophobic stigmatization during adolescence persist into adulthood. School and community interventions should include all types of families in their diversity appreciation programs.
