Factor structure and validation of the juvenile sex offender assessment protocol (J-SOAP).
The Juvenile Sex Offender Assessment Protocol (J-SOAP) was first developed in 1994 in response to the need for a structured method of assessing risk of recidivism among juvenile sexual offenders (R. A. Prentky, B. Harris, K. Frizzell, & S. Righthand, 2000). Over the ensuing years the scale has been subjected to a series of studies that have sought to examine its psychometric properties and its validity. The current paper reports on results from three of these studies, one of which looks at the factor structure of the items. The other two studies examine concurrent validity by looking at J-SOAP Scales 1 and 2 in relation to the Level of Service Inventory-Youth Version with: Youth Level of Service/Case Management Inventory (YLSICMI) (R. D. Hoge & D. A. Andrews, 1996) and other selected variables and discriminant validity by looking at the ability of J-SOAP scales to differentiate between juvenile sex offenders in the community and juvenile sex offenders in residential placement. The revision of the scale is discussed based on the research that has developed the scale and the research that has employed it.
