How does the average practicing psychologist view a gay or lesbian couple wishing to adopt a child? Psychologists (N = 388) from across the United States read and rated 1 of 6 vignettes describing a couple interested in adopting a 5-year-old child. The vignettes were identical except that the couples' sexual orientation was depicted as gay male, lesbian, or heterosexual and the child was either a girl or boy. Results indicated that participants who rated the gay male and lesbian couples with a female child were less likely to recommend custody for these couples than participants who rated the heterosexual couples. Before psychologists provide mental health services to gay and lesbian people and their children, they should complete formal, systematic training on sexual diversity.
