RESUMEN
High risk substance misuse, trauma and gang involvement are prevalent in adolescents and often occur with youth involved with the youth punishment system. Evidence suggests that system involvement is related to trauma histories, substance misuse, as well as gang involvement. This study investigated the associations between individual and peer factors and their relationship to problem drug and alcohol use among Black girls involved with the youth punishment system. Data were collected from 188 Black girls in detention at baseline, as well as 3 and 6 month follow up periods. Measures assessed were abuse history, trauma history, sex while using drugs and alcohol, age, government assistance, and drug use. Significant findings from the multiple regression analyses indicated that younger girls were more likely to have a higher prevalence of having a drug problem than older girls at baseline. Having sex while on drugs and alcohol at the 3 month follow up period was correlated with drug use. These findings highlight how individual and peer factors can influence problem substance misuse, their behavior and peer relationships among Black girls in detention.
