Objectives

Examine 25 years of Sex Offender Registration and Notification (SORN) evaluations and their effects on recidivism.

Methods

We rely on methodology guidelines established by the Campbell Collaboration for meta-analyses to systematically synthesize results from 18 research articles including 474,640 formerly incarcerated individuals. We estimate the effect of SORN policies on recidivism from 42 effect sizes and determine if the effect of SORN varies by sexual or non-sexual recidivism when examining arrest or conviction as outcomes.

Results

The random-effects meta-analysis model demonstrated that SORN does not have a statistically significant impact on recidivism. This null effect exists when examining a combined model and when disaggregating studies by sexual or non-sexual offenses, or conceptualizing recidivism by arrest or conviction.

Conclusions

SORN policies demonstrate no effect on recidivism. This finding holds important policy implications given the extensive adoption and net-widening of penalties related to SORN.

性犯罪者登记和通知的有效性：对 25 年调查结果的荟萃分析

目标

检查 25 年来的性犯罪者登记和通知 (SORN) 评估及其对累犯的影响。

方法

我们依靠 Campbell Collaboration 建立的方法指南进行元分析，以系统地综合 18 篇研究文章的结果，其中包括 474,640 名以前被监禁的人。我们从 42 个效应大小估计 SORN 政策对累犯的影响，并在将逮捕或定罪作为结果检查时，确定 SORN 的影响是否因性或非性累犯而异。

结果

随机效应荟萃分析模型表明 SORN 对累犯没有统计上的显着影响。在检查组合模型以及按性犯罪或非性犯罪对研究进行分类时，或通过逮捕或定罪将累犯概念化时，存在这种无效效应。

结论

SORN 政策表明对累犯没有影响。鉴于与 SORN 相关的处罚的广泛采用和净扩大，这一发现具有重要的政策含义。
