This article reports on a study of 503 African-American, Hispanic, and White non-Hispanic adolescent girls attending public schools in Miami, Florida, The primary objectives of the study were to determine the prevalence of 13 self-reported delinquent behaviors in the sample, to compare these rates among the three groups of students, and to explore the predictive influences of several family factors that correlate with delinquency. It was found that 37.5% of the sample engaged in one or more acts of serious delinquency, with African-Americans reporting they had engaged in significantly more of these behaviors. The best predictors of theft/vandalism were low family pride and family substance abuse for Hispanics, low family communication for African-Americans, and low family pride for White non-Hispanics. The findings indicate that traditional family factors that have been used repeatedly to understand delinquency by male adolescents were not strong predictors of delinquency among the adolescent girls in the sample.
