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.

关于对老龄化罪犯群体使用风险评估工具的信息有限。众所周知，冒犯行为的可能性随着年龄的增长而降低，一小部分男性在生命的后期要么继续或开始进行性冒犯。当前的研究调查了 Static-99 和 Static-99R 的预测有效性，样本是 50 岁及以上的澳大利亚性犯罪者。确定了 118 名参与者的样本，其中 17 人（14.4%）在四个月至 20 年（M = 9.07 年）的随访期内再次犯罪。60 岁以上（n = 52）7 名（13.46%），40 至 59.9 岁（n = 66）10 名。Static-99 和 Static-99R 对两个年龄组均表现出中等的预测有效性。
