Gender differences and conduct disorder among American Indian adolescents in substance abuse treatment.

Studies have found high prevalences of conduct disorder among youth in residential substance abuse treatment programs, but no studies have examined this issue among American Indian adolescents while taking into account gender differences. The Diagnostic Interview Schedule for Children, Youth Version and the Composite International Diagnostic Interview, Substance Abuse Module were used to determine the diagnostic status of 89 American Indian adolescents aged between 13 and 18 years who were admitted to a residential treatment program. Seventy-four percent of the adolescents met full DSM-IV criteria for conduct disorder. More than 85% of the participants met at least one criterion for conduct disorder. Conduct disorder was common among both boys and girls in this sample of American Indian adolescents, but the specific antisocial behaviors displayed and their relationships to other psychiatric disorders varied by gender.
