“…Two well-established JSO risk assessment tools that have received major scientific interest (Hempel et al, 2013;Miccio-Fonseca, 2016;Rettenberger, Klein, Martin, & Briken, 2014;Ryan, 2016) are the Juvenile Sex Offender Assessment Protocol II (J-SOAP II; Prentky & Righthand, 2003) and the Estimate of Risk of Adolescent Sexual Offense Recidivism (ERASOR; Worling & Curwen, 2001). The J-SOAP II (or, more exactly, its precursor J-SOAP (Prentky, Harris, Frizzell, & Righthand, 2000)) has been considered the "pioneer of risk assessment tools" for JSOs (Rasmussen, 2013, p. 124). First introduced in 1994 (Prentky et al, 2000), the instrument underwent a series of studies on its factor structure, reliability, and predictive validity, and was published in its current 28-item format in 2003 (Prentky & Righthand, 2003).…”
