This study used a sample of 293 lesbian, gay, and bisexual youth to examine factors that differentiated youth whose parents knew of their sexual orientation from youth whose parents did not know. Earlier awareness and disclosure of same-gender attractions, greater childhood gender atypicality, and less internalized homophobia were characteristic of youth whose parents were aware of youths sexual orientation. Youth with aware parents reported more past verbal victimization on the basis of sexual orientation from parents, yet more current family support and less fear of future parental victimization on the basis of their sexual orientation.
