Major topics considered include the psychological aspects of the etiology of violence, brain dysfunction in prisoners, methodological problems in the prediction of violence, the psychological treatment of imprisoned offenders, and the prevention of violence. The work emphasizes the fact that there are many types of violence, as well as many causes. Although physical and emotional health are a major factor in violent conduct, it is inappropriate to view violence as a sickness which can be cured. The treatment model may be harmful to most who have committed violent crime; surgery, sedation, and behavior modification have not proven helpful. Several papers suggest that healthy children raised in a decent environment among loving people will rarely commit acts of violence toward others. The capacity for interpersonal violence will increase as society varies from this ideal. An index is provided. For individual papers, see NCJ 87660-72.
