Young people who have broken the law do not have to become criminals in later life, says a new study.
Helmut Remschmidt and Reinhard Walter of the Department of Child and Adolescent Psychiatry and Psychotherapy at Philipps University in Marburg, Germany in their Marburg Child Delinquency Study studied how how often children who were registered by the police as having committed criminal offenses before age 14 (the age of criminal responsibility in Germany) went on to commit further criminal offenses in adulthood.
They also evaluated potential predictors for delinquent behavior. A control group for the study consisted of persons who had not had any contact with the police relating to criminal offenses.
Information on the subjects' further development with respect to the commission of crimes was obtained from their criminal records.
The evaluation of the data revealed that juvenile delinquents fall into two categories: those who become chronic offenders into adulthood and those who are delinquent only in childhood and/or adolescence, but not in adulthood.
Social and familial risk factors were found to be the best predictors of criminal behavior in adulthood, followed by certain personality traits, such as emotional lability and nervousness.
In general, the risk factors for criminality were found to be the same as those for mental illness, yet three risk factors seem to be specific for criminality: male sex, early onset of aggressiveness, and the negative influence of delinquent peers.
The study was published in the current issue of Deutsches Arzteblatt International.
