Long Term Recidivism Rates Among Individuals at High Risk to Sexually Reoffend.

Preventive detention provisions in the US and Canada assume we can identify, in advance, individuals at high risk for sexual recidivism. To test this assumption, 377 adult males with a history of sexual offending were followed for 20 years using Canadian national criminal history records and Internet searches. Using previously collected information, a high risk/high need (HRHN) subgroup was identified based on an unusually high levels of criminogenic needs ( = 190, average age of 38 years; 83% White, 13% Indigenous, 4% other). A subgroup of 99 individuals was then identified based on high Static-99R (6+) and Static-2002R (7+) scores. In the HRHN group, 40% reoffended sexually. STATIC HRHN norms overestimated sexual recidivism at 5 years (Static-99R, = 1.44; Static-2002R, = 1.72) but were well calibrated for longer follow-up periods (20 years: Static-99R, = 1.00; Static-2002R, = 1.16). The overall sexual recidivism rate for the subgroup was 52.1% after 20 years, and 74.3% for any violent recidivism. The highest risk individuals (top 1%) had rates in the 60%-70% range. We conclude that some individuals present a high risk for sexual recidivism, and can be identified using currently available methods.
