Although research on aggressive men and boys has been plentiful, much less attention has been directed toward aggression in girls and women. The increasing number of young women who find themselves living violent lives, both as perpetrators and victims, has led to urgent calls for more information on understanding what causes, what perpetuates and what can be done about this problem. Addressing this need, Girls and Aggression presents a range of interdisciplinary perspectives on risk and protective factors, developmental pathways and intervention principles specific to the problem of aggression and violence in the lives of young women. Contributions come from the fields of psychology, criminology, education, and sociology, and use both qualitative and quantitative methodologies to explore the issues. Girls and Aggression will be of interest to academic researchers and mental health practitioners alike by providing an up-to-date and comprehensive view of this important and underexplored area.
