The reliability and validity of the Sexual Violence Risk-20 (SVR-20): An International Review. Sexual Offender Treatment, 4(2), 1-14.https://hdl.handle.net/10289/6305This article reports on the current state of research about the most commonly used Structured Professional Judgement (SPJ) guidelines for sexual offender risk assessment, the Sexual Violence Risk-20 (SVR-20). After describing the general characteristics as well as frequently discussed strengths and weaknesses of this risk assessment approach, we give an international overview of the empirical results of the reliability and validity of the SVR-20. We conclude by describing briefly a convergent strategy for sexual offender risk assessment incorporating the SVR-20 and offer some future directions for international research on the SPJ approach.application/pdfenThis article has been published in the journal: Sexual Offender Treatment.
