What is it about?

The Static-99, Static-99R, and STABLE-2007 are internationally well-established instruments for the prediction of static and dynamic risks of sexual recidivism in individuals convicted of sexual offenses. This work represents the first meta-analysis to compare the three instruments and their combinations in one analysis.

Why is it important?

Our results suggest that the Static-99R has higher specificity regarding the prediction of the risks of sexual recidivism than the Static-99, indicating a potential advantage in detecting true non-recidivists. The previous notion of incremental validity of the STABLE-2007 could not be confirmed.


The findings may have implications for the current recommendations for assessing the risk of sexual recidivism in the criminal justice system.
