Age at release has become an increasing focus of study with regard to evaluating risk in the sex offender population and has been repeatedly shown to be an important component of the risk assessment equation. This study constitutes an extension of a study of sex offender outcomes prepared for the Evaluation Branch, Correctional Service of Canada. The entire cohort of 2,401 male federally incarcerated sexual offenders who reached their warrant expiry date (WED) within 1997/1998, 1998/1999, and 1999/2000 fiscal years were reviewed for the study. Sexual and violent reconviction information was obtained from CPIC criminal records over an average of 12.0 years (SD = 1.7) follow-up. This study focused upon the cohort of sex offenders who were 50 years or older at time of release (N = 542). They were stratified according to risk using a brief actuarial scale (BARS) comprising six binary variables. For the most part, older offenders showed low base rates of sexual recidivism regardless of the risk band into which they fell. The exception was a small group of elderly offenders (n = 20) who fell into the highest risk band, and who showed high levels of sexual recidivism. The results of this combination of cross-sectional and longitudinal analyses of elderly sexual offenders may have important implications for offender management, particularly in light of the increasing numbers of offenders in Canada who fall into the over 50 age cohort.
就评估性犯罪者群体的风险而言,释放时的年龄已日益成为研究的焦点,并且一再被证明是风险评估方程的一个重要组成部分。本研究是为加拿大惩教服务局评估处准备的一项性犯罪者结果研究的扩展。对在1997/1998年、1998/1999年和1999/2000财政年度内达到其逮捕令到期日(WED)的2401名联邦监禁男性性犯罪者的整个队列进行了研究。通过加拿大警察信息中心(CPIC)犯罪记录,在平均12.0年(标准差 = 1.7)的随访期内获取了性犯罪和暴力再定罪信息。本研究聚焦于释放时年龄在50岁及以上的性犯罪者队列(N = 542)。使用一个由六个二元变量组成的简短精算量表(BARS)根据风险对他们进行分层。在很大程度上,无论属于哪个风险等级,年龄较大的犯罪者性再犯的基础比率都较低。例外情况是一小群属于最高风险等级的老年犯罪者(n = 20),他们表现出较高的性再犯率。对老年性犯罪者进行的这种横断面和纵向分析相结合的结果可能对犯罪者管理具有重要意义,特别是鉴于加拿大50岁以上年龄队列中的犯罪者数量不断增加。
