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.
