The crossover offending section encompasses more than 25 years of research using different methodologies and populations. Although not considered a classification system due to the dynamic nature of the offense pathways, the self-regulation model (SRM) was reviewed due to its clinical utility and relationship to risk. SRM has been validated using several offender populations and methodologies. Due to the limited scope of this chapter, this review focuses on adult sexual offenders, although some juvenile studies are included, where relevant. ( For a discussion of "Etiology and Typologies of Juveniles Who Have Committed Sexual Offenses," see Chapter 2 in the Juvenile section.) Summary of Research Findings
