The dark side of girlhood: recent trends, risk factors and trajectories to aggression and violence.

Introduction: Over the past two decades, rates of aggressive behavior have increased disproportionately for girls as compared to boys. However research on aggressive and violent behavior has focused primarily on boys and consequently we know relatively little about what places girls at risk, what protects them, and how those who become involved in aggressive behavior navigate a path toward adulthood.

Method: In this paper we review recent trends on girls' involvement in aggressive behavior, briefly discuss risk and protective factors, and summarize current thinking on developmental trajectories.

Psychopathy and offending from adolescence to adulthood: a 10-year follow-up.

This study examined the predictive validity of the Hare Psychopathy Checklist: Youth Version (PCL:YV) from adolescence to early adulthood. The authors coded the PCL:YV using file information and collected criminal record information over a 10-year follow-up period on 157 boys, ages 12 through 18, referred to Youth Forensic Psychiatric Services for assessment in 1986. The risk for violence into early adulthood was greater among those with high PCL:YV scores than among those with low scores, even after controlling for conduct disorder, age at first offence, and history of violent and nonviolent offending.
