This book, published by two well-known researchers in the field of violence and mental illness, is a well-documented research project using a longitudinal study of males and females born in 1953, who were either born in Stockholm or raised there from the age of 10, until 1983, when the data were collected. The book is part of the Cambridge Criminology Series and focuses on the relationship between criminality and violent behavior among the mentally disordered. The authors divide the subjects into five general groups: 1) those with diagnoses of major mental disorders, 2) those with alcohol- and/or drug-related disorders, 3) those with other mental disorders, 4) those with mental retardation, and 5) all cohort members who had never been admitted to a psychiatric ward or to a special class in school for retarded children. The last group, which was the most numerous, constituted the control or comparison group. The three major mental illnesses included are schizophrenia, major depression, and bipolar disorder.
