Bullying at School is the definitive book on bully/victim problems in school and on effective ways of counteracting and preventing such problems. On the basis of the author's large-scale studies and other research, it is known that bullying is a serious problem in all societies that have been studied so far, and that more than 15 percent of the school population in primary and secondary/junior high schools are involved, either as bullies or victims. The facts about bullying, its causes and consequences, are presented in clear and straightforward language. The book is a milestone in the study of bullying at school in that it offers a scientifically evaluated intervention program. The results of this extensive research are remarkable: a reduction of bully/victim problems by 50 percent or more a considerable drop in antisocial behavior such as vandalism, theft, drunkenness, and truancy clear improvements in the "social climate" of the classroom and student satisfaction with school life. The book gives practical advice to school principals, teachers, and parents on how to implement a "whole school approach to bullying," and contains a valuable guide to help teachers and parents recognize if a child is being victimized or bullies others. Bullying at School is essential reading for all who are involved with children and young people.
