Juvenile delinquency, adult criminality, and adult psychiatric treatment: an epidemiological study.

This report explores some associations among juvenile-delinquency, subsequent criminality, and subsequent psychiatric treatment. A sample of 255 males known to the juvenile court 25 years prior to the study is examined in terms of subsequent documented psychiatric treatment and/or criminal activity. Of the 255 former delinquents, 6% were known later to both criminal justice and psychiatric systems, 6% to psychiatric systems only, 28% to the criminal justice system only, and 60% to neither. Delinquents with later psychiatric histories were twice as likely to be known to the criminal justice system than were those without psychiatric histories. Those with adult psychiatric histories were also significantly younger at the time of their first delinquent offense and committed more juvenile offenses than the nonpsychiatric group. Only 2 of the 16 individuals later known to both systems were diagnosed sociopathic. The findings are discussed.
