Drug abuse and criminal behavior in delinquent boys committed to a training school

To determine drug use or drug abuse status according to DSM-III criteria, the authors interviewed 109 delinquent boys who had been committed to a training school. They categorized each boy as an offender against a person or as an offender against property only. They found that person offenders were significantly older, came from larger communities, abused a greater number of drugs, had higher asocial index scores, and had lower full-scale IQ scores than property-only offenders. The IQ score and the number of drugs abused were the most important variables predicting whether a subject belonged to the person offender or property-only offender group.
