What Is the Hidden Figure of Delinquency in Girls? Scaling Up From Police Charges to Self-Reports

Research on males shows discrepancies between official records and self-reports of delinquency, thus creating a scaling-up factor. Comparable information for girls is still needed. We investigated discrepancies (scaling up factors) from official records to self-reports in a large sample of girls between ages 12 and 17 (N = 2,450). On average there were three self-reported juvenile female offenders for every individual charged by the police, and for every police charge there were four offenses that were committed. The scaling-up factor was highest in early adolescence, indicating that female offenders at a young age were more likely to stay undetected by the police. The scaling-up factor was significantly lower for African American than white girls: a higher proportion of African American delinquent girls were charged by the police. Racial differences in scaling up were significant only for prevalence, not for frequency of offending. Knowledge about scaling-up factors is important for the design and implementation of intervention programs. We discuss racial differences, implications for justice administration, and practical implications for intervention science.
