Abstract
Using the overarching framework of the risk/needs/responsivity principles of Andrews and Bonta (2006), this chapter identifies the criminogenic needs that have been emerged most consistently as treatment targets for juveniles who have sexually offended (JSOs). Empirical studies supporting the selection of each domain are presented and the assessment tools that have the most research support with JSOs are described and evaluated. The treatment needs reviewed are: hypersexuality and sexual deviance; age and gender sexual preferences; antisocial behavior; callous-unemotional trait; aggressive fantasies and behavior; intimacy and friendships; and victimization. We recommend that clinicians assessing JSOs either generate their own batteries from the reviewed tools or select instruments using different methods that have been created to assess all of the critical domains.
