Differences in risk for Sexual Violence Protocol (RSVP) risk factors among older and adult men who have sexually offended

Ageing has a protective impact on recidivism risk, including for those who offend sexually (Ambroziak, G., Kahn, R. E., Mundt, J. C., Keiser, K. L., & Thornton, D. (2020). Are civilly detained and committed sexually violent persons released after age 60 low risk? Criminal Justice and Behavior, 48(7), 981–998; Doren, D. M. (2006). What do we know about the effect of aging on recidivism risk for sexual offenders? Sexual Abuse: A Journal of Research and Treatment, 18; Harris, G. T., & Rice, M. E. (2007). Adjusting actuarial violence risk assessments based on aging or the passage of time. Criminal Justice and Behavior, 34(3), 297–313). Recent research of the Risk for Sexual Violence Protocol (RSVP) suggests increased age may affect the validity of this guideline, with good predictive performance in samples of men mostly aged under 50 (Davis, M. R., Woods, M., Raymond, B., Ogloff, J. R. P., & McEwan, T. E. (in submission). Does it work?

Convergent and predictive validity of the sexual violence risk-20 and risk for sexual violence protocol with older sexual offenders. Manuscript submitted for publication). This study investigated possible reasons for these contrasting results by investigating age-related differences in risk factor endorsement and the relationships between risk factors. RSVP risk factors in two samples of men with prior sexual offending, older adults aged between 50 and 78 (n = 95) and adults aged between 18 and 46 (n = 139). Few differences were identified in risk factor endorsement or the relationship between risk factors. The younger adult sample were observed to have more risk factors present.
