Reliability and Predictive Validity of the Juvenile Sex Offender Assessment Protocol-II in an Australian Context.

This study investigated the reliability and predictive validity of the Juvenile Sex Offender Assessment Protocol-II (J-SOAP-II), in an Australian context, and for Australian Indigenous and non-Indigenous youth. Participants were 123 (n = 91 non-Indigenous; n = 32 Indigenous) youth assessed using the J-SOAP-II and followed up over an average period of 4 years. The reliability of the J-SOAP-II was assessed using measures of internal consistency (Cronbach's alphas and inter-item correlations). Receiver operating characteristic (ROC) analyses were conducted to assess the J-SOAP-II's validity in predicting sexual and non-sexual (violent and non-violent) recidivism. Overall, the J-SOAP-II demonstrated moderate to high levels of reliability and weak to moderate levels of validity for predicting sexual and non-sexual (violent and non-violent) recidivism for the whole sample. While the J-SOAP-II total score was significantly associated with non-sexual (violent and non-violent) recidivism for non-Indigenous youth, it was not significantly associated with any of the outcome variables for Indigenous youth. Across all analyses, the dynamic scales of the J-SOAP-II predicted recidivism with greater accuracy than the static scales. However, the static scales had greater accuracy in predicting the risk of sexual recidivism for Indigenous youth. While a reliable measure, these preliminary findings raise questions about the validity of the J-SOAP-II for predicting sexual recidivism for Indigenous and non-Indigenous youth in an Australian context, and warrant further investigation.

Validity of Risk Assessment Instruments Among Juveniles Who Sexually Offended: Victim Age Matters.

Research has identified meaningful subtypes among the heterogeneous population of juveniles who sexually offended (JSO). However, studies that test the validity of risk assessment tools with JSO subtypes are limited. This study compared JSO who offended against a child victim (JSO-C) and JSO who offended against an adolescent/adult victim (JSO-A) with regard to rates of recidivism and the predictive validity of two risk assessment tools (Estimate of Risk of Adolescent Sexual Offense Recidivism [ERASOR] and Juvenile Sexual Offender Assessment Protocol-II [J-SOAP-II]). Data were analyzed from case files of 185 JSO-C and 297 JSO-A aged 12 to 18 years (M = 14.11, SD = 1.44) from a consecutive sample of JSO with contact sexual offenses. A total of 34 (7.1%) juveniles reoffended sexually, with no significant difference between the subtypes. The present results suggest that the ERASOR, particularly the structured professional judgment, and to a lesser degree the J-SOAP-II are better suited to predicting sexual recidivism in JSO-A than in JSO-C.

Long-Term Predictive Validity of the Juvenile Sex Offender Assessment Protocol-II: Research and Practice Implications.

The current study evaluated the predictive validity of the Juvenile Sex Offender Assessment Protocol-II (J-SOAP-II) scores in a sample of juveniles who recidivated sexually or nonsexually as adults. Participants included 166 juveniles who had previously sexually offended and were followed into adulthood for an average of 10.75 years. Results of area under the receiver operating characteristic curve (AUC) analyses supported the predictive validity of the J-SOAP-II Total Score, Scale 1, and Static Score in regard to adult sexual recidivism, and predictive validity was found for all J-SOAP-II scores (except Scale 1) in regard to adult nonsexual recidivism. Implications for future research on the assessment of risk factors and treatment needs for adolescents who commit sexual offenses are discussed.

Are Juveniles Who Have Committed Sexual Offenses the Same Everywhere? Psychometric Properties of the Juvenile Sex Offender Assessment Protocol-II in a Portuguese Youth Sample.

Over the last decade, we have witnessed consistent advances in risk assessment procedures, namely the validation of those used with juveniles who have committed sexual offenses. The adaptation of these instruments into other languages requires research examining the conceptual and metric equivalence of the instruments, not just translation equivalence. Informed by data from 141 boys, aged 13 to 18, the psychometric properties of the Portuguese version of the Juvenile Sex Offender Assessment Protocol-II (J-SOAP-II), regarding reliability and construct validation, are presented and discussed. Factor structure, internal consistency, and interrater reliability were examined, and a reliable factorial structure that was consistent with the original validation of the J-SOAP was found. Scales 2 and 3 had good internal consistency, and Scale 1 had acceptable internal consistency. Results regarding concurrent validity revealed mostly statistically significant correlations. The implications of this research for juvenile sex offender risk assessments are discussed.

Scientific Evolution of Clinical and Risk Assessment of Sexually Abusive Youth: A Comprehensive Review of Empirical Tools.

Risk assessment of sexually abusive youth is a specialty, which ideally includes a clinical assessment (e.g., psychological evaluation) utilizing a validated risk assessment tool. This article reviews tools for assessing sexual improprieties and/or sexually abusive behaviors in youth: JSORRAT-II, J-SOAP-II, J-RAS, AIM2, and MEGA♪,1 and a clinical assessment tool, MIDSA. Untested, structured, clinical checklists with face validity, J-RAT-4 and PROFESOR, are included. The authors also highlight clinical dilemmas using "utility tools" (i.e., polygraph and plethysmograph) with sexually abusive youth. The comprehensive review sustains a twenty-first-century New Paradigm of inclusive ecologically based, developmentally and gender-sensitive assessment tools that definitively and accurately assess risk and protective factors of sexually abusive youth.

The Influence of Age and Sexual Drive on the Predictive Validity of the Juvenile Sex Offender Assessment Protocol-Revised.

The Juvenile Sex Offender Assessment Protocol-Revised (J-SOAP-II) is the most commonly used measure in the assessment of recidivism risk among juveniles who have committed sexual offenses (JSOs), but mixed support exists for its predictive validity. This study compared the predictive validity of the J-SOAP-II across two offender characteristics, age and sexual drive, in a sample of 156 JSOs who had been discharged from a correctional facility or a residential treatment program. The J-SOAP-II appeared to be a better predictor of sexual recidivism for younger JSOs (14-16 years old) than for older ones (17-19 years old), with significant differences found for the Dynamic Summary Scale and Scale III (Intervention). In addition, several of the measure's scales significantly predicted sexual recidivism for JSOs with a clear pattern of sexualized behavior but not for those without such a pattern, indicating that the J-SOAP-II may have greater clinical utility for JSOs with heightened sexual drive. The implications of these findings are discussed.

Changes in J-SOAP-II and SAVRY Scores Over the Course of Residential, Cognitive-Behavioral Treatment for Adolescent Sexual Offending.

Although the Juvenile Sex Offender Assessment Protocol-II (J-SOAP-II) and the Structured Assessment of Violence Risk in Youth (SAVRY) include an emphasis on dynamic, or modifiable factors, there has been little research on dynamic changes on these tools. To help address this gap, we compared admission and discharge scores of 163 adolescents who attended a residential, cognitive-behavioral treatment program for sexual offending. Based on reliable change indices, one half of youth showed a reliable decrease on the J-SOAP-II Dynamic Risk Total Score and one third of youth showed a reliable decrease on the SAVRY Dynamic Risk Total Score. Contrary to expectations, decreases in risk factors and increases in protective factors did not predict reduced sexual, violent nonsexual, or any reoffending. In addition, no associations were found between scores on the Psychopathy Checklist:Youth Version and levels of change. Overall, the J-SOAP-II and the SAVRY hold promise in measuring change, but further research is needed.
