Lifetime Sexual Recidivism of Adult Justice-Involved Individuals: A 30-Year Prospective Longitudinal Study

Area of Science:

• Criminology
• Forensic Psychology
• Longitudinal Studies

Background:

• Debate exists regarding long-term sexual recidivism rates for sex offenders, with older estimates (40-60%) contrasting with newer ones (20-30%).
• Higher historical rates may be attributed to older, higher-risk samples not representative of current populations.

Purpose of the Study:

• To prospectively examine long-term sexual recidivism risk in a cohort of adults incarcerated for sexual offenses.
• To evaluate the predictive accuracy of risk assessment tools (Static-99R, Static-2002R) over extended follow-up periods.

Main Methods:

• A 30-year prospective longitudinal study followed 553 individuals released from Canadian penitentiaries.
• Data collected included cumulative sexual recidivism rates at 5, 10, 20, and 25 years post-release.
• The predictive performance of Static-99R and Static-2002R was assessed using receiver operating characteristic (ROC) analysis.

Main Results:

• Cumulative sexual recidivism rates were 9% at 5 years, 15% at 10 years, 19% at 20 years, and 20% at 25 years.
• Static-99R demonstrated moderate predictive accuracy (AUC = 0.662 for total score, 0.639 for risk level).
• Other factors, such as custody and community re-entry experiences, outperformed Static-99R and Static-2002R in predicting recidivism.

Conclusions:

• Long-term sexual recidivism rates appear to be lower than previously estimated.
• While Static-99R and Static-2002R offer some predictive value, they are less effective than other contextual factors.
• Further research is needed to identify distinct risk and protective factors for short-, moderate-, and long-term recidivism.
