Validity of the Juvenile Sex Offender Assessment Protocol—II (J-Soap-II) in a Sample of Urban Minority Youth

Abstract

Despite recent advances in risk assessment procedures, relatively little research has targeted validation of procedures with sexually offending minority youth. The current study used retrospective coding of the Juvenile Sex Offender Assessment Protocol—II (J-SOAP-II; Prentky & Righthand, 2003) with a group of 60 male youth of mostly Latino and African American ethnicity. Correlational and receiver operating curve (ROC) analyses were used to test the J-SOAP-II's relationship with and accuracy in predicting general reoffense, sexual reoffense, and treatment compliance. The J-SOAP-II total score was significantly correlated with all three of these outcome variables, and ROC analyses demonstrated a high degree of accuracy in predicting general (area under the curve [AUC] = .76) and sexual reoffending (AUC = .78). There was mixed support for the J-SOAP-II individual subscales, with Dynamic subscales consistently outperforming Static subscales. The implications of this research for juvenile sex-offender risk assessments are discussed.
