Abstract
There is limited information regarding the use of risk assessment tools with aging offender populations. It is known that the likelihood of offending behaviour decreases with age, a small group of men either continue or begin to offend sexually in the later decades of life. The current study investigated the predictive validity of the Static-99 and the Static-99R, in a sample of convicted Australian sex offenders aged 50 and older. A sample of 118 participants was identified, of which 17 (14.4%) re-offended within a follow-up period ranging from four months to 20 years (M = 9.07 years). There were seven recidivists (13.46%) above the age of 60 years (n = 52) and 10 aged 40 to 59.9 years (n = 66). Both the Static-99 and Static-99R demonstrated moderate predictive validity with both age groups. The limitations of this study are discussed as well as recommendations for future research.
