Development of an object relation–based typology of adolescent sex offenders

Published Online:

The aim of this study was to develop a typology of adolescent sex offenders based on object relations theory and Otto F. Kernberg's model of personality organizations (PO). A secondary objective was to compare the identified subtypes on offense characteristics as well as some psychological variables of adolescent sex offenders. Clinical files from 40 male adolescent sex offenders in treatment were examined. Cluster analysis based on PO and object relations variables identified six subtypes of offenders, in line with Kernberg's PO model. These subtypes differed from one another on various variables pertaining to characteristics of sex offenses, general delinquency, relational/sexual history, and trauma history.
