Research evidence on bully-victim problems has accumulated rapidly in recent years. From this, there is little doubt that prolonged involvement in bullying, as a perpetrator, victim, or, not uncommonly, as both a perpetrator and target of bullying, conveys risk for many aspects of development. As in many emerging areas of psychological science, diverse research efforts evolved more or less independently, producing a very large and rich body of knowledge, but making it difficult to gain a comprehensive, integrated view of the overall evidence base. Preventing and Treating Bullying and Victimization looks across the sometimes disparate perspectives from school, clinical, and developmental researchers and professionals with an eye towards describing and integrating current knowledge into a guide for evidence-based practices and further research. The authors offer new directions for understanding this complex problem and for enhancing intervention approaches. This edited book will be comprised of three sections: Theoretical Perspectives, Assessment and Intervention, and Recommendations for Policy, Practice, and Research. It will be of interest to a number of professions and disciplines including clinical, developmental, counseling, and school psychologists, social workers, school administrators and educators, and public officials involved in setting policies.
