For over 30 years, general cognitive-behavioral programs have contributed to the rehabilitation services offered within His Majesty's Prison and Probation Service in England and Wales. There is an extensive body of international evidence that demonstrates the effectiveness of such interventions as a correctional strategy. However, there is widespread variability of program effects associated with the standards of implementation. Over the last 3 decades, British researchers have produced a steady output of quasi-experimental program evaluations that have contributed to the evidence base. The most recent additions are some of the largest and most rigorous available worldwide. This review documents those evaluations and provides a meta-analysis that statistically aggregates the effects of programs delivered in His Majesty's prisons in England and Wales. We suggest there is sufficient evidence from evaluations of acceptable scientific rigor to conclude that general cognitive-behavioral programs delivered in prisons during the last decade and a half (circa 2006 to 2019) have had a small statistically significant mean reductive effect on general reoffending (odds ratio = 0.91). Program characteristics and implementation factors, including program dose, the scale of service delivery and program integrity, are discussed as possible factors associated with the size of the effect.

对英国和威尔士监狱和缓刑服务的一般认知行为计划的回顾：三十年的准实验评估。


30 多年来，一般认知行为计划为英格兰和威尔士的 His Majesty's Prison and Probation Service 提供的康复服务做出了贡献。有大量的国际证据表明，这种干预措施作为一种矫正策略是有效的。但是，与实施标准相关的程序效果存在广泛的可变性。在过去的 3 年里，英国研究人员稳定地产生了准实验性项目评估，这些评估为证据基础做出了贡献。最近添加的是全球范围内规模最大、最严格的指标。本综述记录了这些评估，并提供了荟萃分析，统计汇总了在英格兰和威尔士陛下监狱实施的项目的效果。我们建议从可接受的科学严谨性评估中得出足够的证据来得出结论，在过去十五年（大约 2006 年至 2019 年）期间在监狱中提供的一般认知行为计划对一般再犯罪有很小的统计学显着平均还原效应（比值比 = 0.91）。讨论了项目特征和实施因素，包括项目剂量、服务交付规模和项目完整性，作为与效果大小相关的可能因素。（PsycInfo 数据库记录 （c） 2024 APA，保留所有权利）。
