This article compares responses of three groups of incarcerated adolescents who admitted to sexual offending in an anonymous survey project on measures of trauma, sexual offending, the relationship between trauma and perpetration, and adjudication status. The first group admitted to sexual offending before the age of 12 only (n = 48), the second after the age of 12 only (n = 130), and the third before and after the age of 12 (n = 65). More than
46% of the
sexually aggressive adolescents began their deviant behaviors before the age of
12.
Level and
complexity of
perpetration acts were more severe for the continuous offenders than for the other groups. Victimization and perpetration were significantly correlated for all three groups. This study supports a social learning hypothesis for the development of sexual offending by adolescents. Implications for research and clinical practice are drawn.
