Brief report: Parsing the heterogeneity of adolescent girls' sexual behavior: Relationships to individual and interpersonal factors

Clusters of pre-sexual and sexual behaviors were identified in an urban US sample of 546 mid-adolescent girls. No distinct group of girls engaging in sexually risky behavior was revealed. Sexually active girls were older, lived with a single parent, and reported more substance use and depression, but similar levels of conduct problems, impulsivity and deviant peers to girls engaging in pre-sexual behavior.
