This study is a longitudinal analysis of STD/HIV exposure among adolescent female offenders in Mississippi, a population that is disproportionately African American, and at higher risk than adolescents in general due to their propensity to engage in a variety of risk-taking behaviors, earlier onset of sexual behaviors, and the greater prevalence of mental disorders, substance abuse disorders, maltreatment, and family dysfunction. Based on social cognitive theory and Fisher and Fisher's (1992) IMB (Information, Motivation, and Behavioral skills) model, we will evaluate a drug abuse related HIV risk reduction intervention and compare outcomes against a STD/HIV information and health education control condition.
